## Title
Article of footwear including knitting a knitted component of warp knit construction forming a seamless bootie

## Abstract

An article of footwear incorporates a seamless bootie or textile upper formed from a knitted component removed from a knitted textile element of unitary warp knit construction. The knitted component may include a first knitted component portion in the form of a seamless bootie and a second knitted component portion associated with the first knitted component portion. In some embodiments the second knitted component portion may be tucked-in or folded into a pocket of first knitted component portion, such as a knitted dynamic fit component portion or a knitted tongue component portion. In some embodiments the second knitted component portion may be wrapped around at least part of the first knitted component portion.

## Background
BACKGROUND
The present embodiments relate generally to methods of making articles of footwear and in particular to methods of knitting a knitted component of warp knit construction for forming a seamless bootie or textile upper.
Articles of athletic footwear generally include two primary elements, an upper and a sole structure. An upper generally provides a covering for a foot that securely receives and positions the foot with respect to the sole structure. The upper may have a configuration that protects the foot. The upper may have a construction that provides ventilation to an interior of the upper, thereby facilitating cooling of the foot and/or removing perspiration from the foot. The sole structure may be secured to a lower surface of the upper and may be generally positioned between the foot and a ground surface during use of the article of footwear. The sole structure may be configured for attenuating impact and other ground surface reaction forces and absorbing energy, i.e., providing cushioning to the foot during use of the article of footwear. The sole structure may provide traction relative to a ground surface. The sole structure may help to control foot motion during use of the article of footwear. The upper and the sole structure may cooperate to provide a comfortable structure that may be suited for a wide variety of ambulatory activities, such as walking and running.
The upper may form a void on the interior of an article of footwear for receiving a foot. The void may have a general size and/or shape of the foot. The upper may have an opening that provides access to the void, such as an ankle opening. The upper may extend over an instep and toe areas of the foot, along medial and lateral sides of the foot, and/or around a heel area of the foot. The upper may include a fastening or closure system, such as a strap or lacing system, that selectively adjusts a size of the opening (e.g., an ankle opening). Such structure enables the wearer to modify certain dimensions of the upper, particularly girth, to accommodate different feet with varying proportions. The upper may include a tongue associated with an opening and/or closure system. For example, a tongue may be disposed between a lacing system and a foot to enhance the comfort of the article of footwear. The upper may include a heel counter to limit movement of the foot in the heel region.
Materials selected for the upper may vary significantly. Textile materials often form at least a portion of the exterior surface and interior surface of the upper. A textile may be defined as any manufacture made from fibers, filaments, or yarns characterized by flexibility, fineness, and a high ratio of length to thickness. Textiles generally fall into one of two categories. A first category includes textiles produced directly from a web or mat of filaments or fibers by randomly interlocking the filaments or fibers to construct non-woven fabrics and felts. A second category includes textiles formed through a mechanical manipulation of yarn, such as a woven or knit fabric.

Seamless Bootie or Textile Upper Article of Footwear Configurations
This section generally describes embodiments of methods for knitting a knitted textile element including a knitted component that is configured to form a seamless bootie or textile upper for an article of footwear.
FIG. 1 is an isometric top front view of an embodiment of an article of footwear 100, also referred to as article 100. In some embodiments, article 100 may take the form of an athletic shoe or sports related footwear including, but not limited to: hiking boots, soccer shoes, football shoes, sneakers, running shoes, cross-training shoes, rugby shoes, basketball shoes, baseball shoes, as well as other kinds of athletic shoes or footwear. In some embodiments, article 100 may take the form of various kinds of non-sports related footwear including, but not limited to: slippers, sandals, high heeled footwear, loafers, as well as any other kind of footwear and/or apparel.
As shown in FIG. 1, in some embodiments article 100 may include an upper 102 and an optional sole structure 104. Sole structure 104 may be secured to upper 102 and extend between the foot and a ground surface when article 100 is worn. In some embodiments, sole structure 104 may be configured to provide traction for article 100. In some embodiments, sole structure 104 may be configured to absorb or attenuate impact or other ground reaction forces when compressed between the foot and the ground surface during walking, running, or other ambulatory activities.
The configuration of sole structure 104 may vary significantly in different embodiments to include a variety of known or newly developed sole structures and/or components. For example, sole structure 104 variously may include an outsole, a midsole, and/or an insole. In some cases, one or more of these components may be optional. In some cases, sole structure 104 itself may be optional. In some cases, the configuration of sole structure 104 may be selected to be suitable for one or more type of ground surface on which sole structure 104 may be used. Example ground surfaces may include, but are not limited to: natural turf, synthetic turf, dirt, sand, gravel, snow, ice, as well as other surfaces.
Upper 102 may be configured to receive and cover a foot. In some embodiments, upper 102 may include an opening 106 that provides entry to an interior of upper 102. For example, as shown in FIG. 1, in some embodiments opening 106 may be an ankle opening.
In some embodiments, upper 102 may include a fastening or closure structure or other provisions for tightening or otherwise adjusting fit characteristics (e.g., girth) of upper 102. For example, in some embodiments upper 102 may include tensioning members, such as lacing members 122 and eyelets 124 for receiving one or more lace or other tensioning member (such as a cable) 126. In this manner, a size of opening 106, and a corresponding girth of upper 102 may be adjusted to customize a fit of upper 102 and article of footwear 100. In some embodiments, lacing members 122 of the closure structure may provide reinforcing edge structure and form an opening having a V-shaped configuration, a U-shaped configuration, or another configuration. In some embodiments, as shown in FIG. 1, a closure structure having a V-shaped configuration may provide improved performance characteristics, such as comfort and fit. For example, in some cases a V-shaped closure configuration may enable tighter closure across a forefoot and/or instep region of upper 102 and article of footwear 100 without causing buckling in the forefoot region of the upper that may result from tightening a closure structure having a square or U-shaped configuration. In other embodiments, a closure system may provide reinforced edge structure at a terminal portion adjacent the forefoot region of upper 102. Those skilled in the art readily will be able to select a shape and configuration of a closure system suitable for desired fit and performance characteristics of upper 102 and article of footwear 100.
In some embodiments, upper 102 may include a tongue 130 (illustrated in phantom in FIG. 1). Tongue 130 may be disposed between a fastening or closure structure and a foot to facilitate comfort and fit. For example, tongue 130 may be disposed between lacing members 122 and a foot—between eyelets 124 and a foot—or between lacing 126 and a foot received in the interior of upper 102. It will be appreciated that a tongue may be optional in some embodiments.
In some embodiments, upper 102 may be substantially formed by a unitary knitted component 140 in the form of a seamless bootie that may extend through each of a forefoot region 142, a midfoot region 144, and a heel region 146, and along both a lateral side 148 and a medial side 150. This is in contrast to many known footwear uppers that are formed from multiple material elements (e.g., textiles, polymer foam, polymer sheets, leather, synthetic leather) that are joined through stitching or bonding, for example. In some embodiments, knitted component 140 may also include tongue 130. Knitted component 140 may form portions of both an exposed exterior surface and an opposite interior surface of upper 102. As such, knitted component 140 may define at least a portion of the void within upper 102. Knitted component 140 also extends under the foot. In some embodiments, article of footwear 100 may include a sole structure, and a portion of knitted component 140 may extend under the foot. In this construction, the knitted component may replace or function as a sock liner.
As described in further detail below, knitted component 140, which may form a substantial majority of upper 102, generally comprises a knit material, such as from a knitted textile element. As such, in some embodiments upper 102 may be substantially flexible and lightweight relative to some other known upper materials. Although some embodiments disclosed herein may illustrate an upper comprised entirely of a knit material, other embodiments of an upper may be only partially comprised of a knit material (or textile material).
In some embodiments, upper 102 may include one or more holes, apertures, perforations, openings, gaps, slots, or other such structures, hereafter generally referred to as holes. Upper 102 may include various groups of holes arranged in various configurations and in various locations, collectively referred to herein as plurality of holes 152. However, in some embodiments such holes may be optional. In some embodiments some holes may extend through the entire thickness of upper 102, while other holes may extend only partially through the thickness of upper 102. The particular number, sizes, shapes, alignment, and configurations of holes within plurality of holes 152 may vary from one embodiment to another. A specific configuration of plurality of holes 152 may be selected to achieve desired performance characteristics of upper 102, such as general or localized breathability of upper 102, and/or a general or localized stretching or pliability characteristic of upper 102. For example, larger numbers and/or larger sizes of holes may provide a greater localized or general pliability and stretching of a fabric. Alternatively, different patterns of holes, such as in'-line, staggered, or offset patterns, may provide different localized and/or general pliability, stretching, and/or ventilation characteristics. A specific configuration of plurality of holes 152 also may be selected to provide aesthetic appeal.
For purpose of reference, upper 102 and/or article of footwear 100 generally may be divided into a forefoot portion 160, a midfoot portion 162, and a heel portion 164. Forefoot portion 160 generally may be associated with a toe box for the toes and joints connecting the metatarsals with the phalanges. Midfoot portion 162 generally may be associated with the instep and/or arch of a foot. Heel portion 164 generally may be associated with the heel of a foot, including the calcaneus bone. Upper 102 also generally may include a lateral side portion 166 and a medial side portion 168. Lateral side portion 166 and medial side portion 168 may be opposing sides of upper 102. One or both of lateral side 166 and medial side 168 may extend through forefoot portion 160, midfoot portion 162, and heel portion 164. Some embodiments further may include a front toe portion 154 as well as a vamp or instep portion 156.
As used in this description, the terms forefoot portion or region, midfoot portion or region, heel portion or region, toe portion or region, and instep portion or region are only intended for purposes of description and are not intended to demarcate precise portions or boundaries of upper 102. Likewise, the terms lateral side (or lateral portion) and medial side (or medial portion) are intended to represent generally two sides of an article, rather than precisely demarcating upper 102 into two halves.
As noted above, upper 102 may be at least partially formed from a knitted component 140. Knitted component 140 may be removed from a knitted textile element that includes an approximately flat, two dimensional, layered construction that is configured to be separated (e.g., cut open) and formed or shaped to extend around the foot. As depicted in FIG. 1, in some embodiments knitted component 140 forms both an exposed exterior or outer side (or outer surface) of upper 102, facing away from the foot, and an interior or inner side (or inner surface) of upper 102 facing inward toward the foot.
As discussed in further detail below, knitted component 140 may be formed of unitary warp knit construction as a part of a larger knitted textile element. In this case, knitted component 140 may be removed from the larger knitted textile element and various features of knitted component 140 may be manipulated and/or treated to form a desired shape of upper 102.
In some embodiments, a single knitted textile element may include multiple knitted components, which may be removed to form separate components. For example, first and second knitted components of a single knitted textile element may correspond to a matching pair of left and right seamless booties or textile uppers for articles of footwear. Alternatively, first and second knitted components of a single knitted textile element may correspond to a seamless bootie or textile upper and an associated tongue or other accessory for an article of footwear. It will be appreciated that a knitted textile element may include addition numbers and/or kinds of knitted components.
Knitted component 140 may impart a variety of features or performance characteristics to upper 102. Knitted component 140 may provide a variety of advantages over some known upper configurations. As noted above, known footwear uppers may be formed from multiple material elements (e.g., textiles, polymer foam, polymer sheets, leather, synthetic leather) that are joined at one or more seams through stitching or bonding, for example. As the number and type of material elements incorporated into an upper increases, the time and expense associated with transporting, stocking, cutting, and joining the material elements may also increase. Waste material from cutting and stitching processes also may accumulate to a greater degree as the number and type of material elements incorporated into the upper increases. Uppers having a greater number of material elements may be more difficult to recycle than uppers formed from fewer types and numbers of material elements. Decreasing the number of material elements utilized in making the upper, therefore, may decrease waste while increasing manufacturing efficiency and recyclability of the upper. To this end, in some embodiments knitted component 140 may form a substantial portion of upper 102, thereby increasing manufacturing efficiency, decreasing waste, and simplifying recyclability.
Embodiments of upper 102 also may utilize one or more reinforced portions. As used in this disclosure, the term reinforced portion refers to any portion of an upper that incorporates any additional material(s) within one or more layers of knitted component 140. A reinforced portion may comprise separated layers of knitted component 140 that are filled with a reinforcing material, such as an insert member. An insert member may be selected based on a desired performance characteristic of the upper, such as leather or plastic for rigidity, or foam rubber for cushioning. An insert member may be located in a particular region of an upper to provide a localized or general performance characteristic to the region or upper. A reinforced portion may impart increased strength and/or reinforcement for the upper, and/or increased cushioning and comfort, depending on the insert material used. For example, in some embodiments a tongue 130 may include a two layer knitted component having an insert member (or reinforcing portion) that is a foam material inserted between two layers of the knitted component. In some embodiments a toe or heel region may include an insert member (or reinforcing portion) in the form of a toe or heel cap that is a rigid material inserted between layers of the knitted component or between a layer and a strap or other knitted structure of the knitted component.
Knitted component 140 may be formed of unitary warp knit construction using a warp knitting machine and a warp knitting process. In some embodiments, a flat warp knitting machine may be used to form a knitted component of unitary warp knit construction. In some embodiments, knitted component 140 may be formed as a tubular textile of unitary knit construction using a warp knitting machine having two sets of needles.
As used herein and in the claims, a knitted component is defined as being formed of “unitary knit construction” when formed as a one-piece element through a knitting process. That is, the knitting process substantially forms the various features and structures of a knitted component without the need for significant additional manufacturing steps or processes. A unitary knit construction may be used to form a knitted component having structures or elements that include one or more courses or wales of yarn or other knit material that are joined such that the structures or elements include at least one course or wale in common (i.e., sharing a common yarn) and/or include courses or wales that are substantially continuous between each of the structures or elements. With this arrangement, a one-piece element of unitary knit construction is provided. In embodiments where a warp knitting process is used to form a knitted component, the knitted component may be formed of unitary warp knit construction and may have structures or elements that include one or more wales of yarn or other knit material that are joined such that the structures or elements include at least one wale in common (i.e., sharing a common yarn) and/or include wales that are substantially continuous between each of the structures or elements.
As used in this disclosure, yarn is generally defined as an assembly having a substantial length and relatively small cross-section that is formed of at least one filament or a plurality of fibers. A filament may have an indefinite length and may be used alone or in combination with one or more other filaments to produce a yarn suitable for use in textiles. Modern filaments include a plurality of synthetic materials such as rayon, nylon, polyester, and polyacrylic, with silk being the primary, naturally-occurring exception. Fibers may have a relatively short length and require spinning or twisting processes to produce a yarn of suitable length for use in textiles. Examples of fibers include cotton and wool. Yarn may be formed of a single filament, which is conventionally referred to as a monofilament yarn, or a plurality of individual filaments grouped together. Yarn may include separate filaments formed of different materials. Yarn may include filaments that are each formed of two or more different materials. Similar concepts apply to yarns formed from a plurality of fibers. Accordingly, yarns may have a variety of configurations that generally conform to the definition provided above. Those skilled in the art will be able to select one or more known or later developed yarn(s) suitable for a desired application based on characteristics of the yarn and a desired performance characteristic of the knitted component 140.
Knitted component 140 may incorporate various types of yarn that impart different properties to separate areas of upper 102 and/or tongue 130. That is, one portion of knitted component 140 may be formed from a first type of yarn that imparts a first set of properties, and another portion of knitted component 140 may be formed from a second type of yarn that imparts a second set of properties. In this configuration, properties may vary throughout upper 102 and/or tongue 130 by selecting specific yarns for different portions of knitted component 140. The properties that a particular type of yarn will impart to a portion of knitted component 140 partially depends upon the materials that form the various filaments and fibers within the yarn. Cotton, for example, provides a soft hand, natural aesthetics, and biodegradability. Elastane and stretch polyester each provide substantial stretch and recovery, with stretch polyester also providing recyclability. Rayon provides high luster and moisture absorption. Wool also provides high moisture absorption, in addition to insulating properties and biodegradability. Nylon is a durable and abrasion-resistant material with relatively high strength. Polyester is a hydrophobic material that also provides relatively high durability.
In addition to materials, other aspects of the yarn(s) selected for knitted component 140 may affect the properties of upper 102 and/or tongue 130. For example, a yarn forming knitted component 140 may be a monofilament yarn or a multifilament yarn. The yarn may include separate filaments that are each formed of different materials. The yarn may include filaments that are each formed of two or more different materials, such as a bicomponent yarn with filaments having a sheath-core configuration or two halves formed of different materials. Different degrees of twist and crimping, as well as different deniers, may also affect properties of upper 102 and/or tongue 130. Accordingly, both the materials forming the yarn(s) and other aspects of the yarn(s) may be selected to impart a variety of properties to separate areas of upper 102 and/or tongue 130.
Generally, a textile may be formed from one or more yarns that are mechanically-manipulated through either an interweaving, intertwining and twisting, or interlooping process, for example. Interweaving is the intersection of two yarns that cross and interweave at right angles to each other. Yarns utilized in interweaving are conventionally referred to as warp and weft. Intertwining and twisting encompasses procedures such as braiding and knotting where yarns intertwine with each other to form a textile. Interlooping involves the formation of a plurality of columns of intermeshed loops, with knitting being a common method of interlooping. A textile element may, therefore, be formed from one of these processes for manufacturing a textile. In some embodiments, a knitted textile element may be formed using a knitting process.
A variety of mechanical processes have been developed to manufacture a textile through knitting. In general, mechanical processes may be classified as either warp knitting or weft knitting. As used in this description, warp knitting refers to a type of knitting method in which a yarn zigzags along the length of the textile, i.e., following adjacent columns or wales of knitting, rather than along a single row or course. For comparison, as used in this description weft knitting refers to knitting across the width of the textile. Various specific sub-types of warp knitting that may be utilized to manufacture a textile include tricot, raschel, and double needle-bar raschel (which further includes jacquard double needle-bar raschel).
In some embodiments, a knitted textile element may be manufactured using a warp knitting process. Thus, in some embodiments a knitted component 140 included in a knitted textile element of warp knit construction may comprise a warp knit material (e.g., knitted component 140 may be a warp knitted component). Using a warp knitted textile element may help reduce the tendency of periphery or exposed edges of knitted component 140 to unravel as a result of knitted component 140 being removed or otherwise separated, e.g., cut out, from a knitted textile element. In an exemplary embodiment, a knitted textile element may be formed of unitary knit construction through a warp knitting process and may include one or more knitted components, including one or more uppers and/or tongues, formed together on the same knitted textile element.
In some embodiments, a knitted textile element may be manufactured using different yarns to form one side and another side. For example, in some embodiments a knitted textile element may be manufactured using different yarns to form an exposed outer side and an inner side. By using distinct yarns on the exposed outer side and the inner side, a knitted textile element can be manufactured to have different knitting configurations on the exposed outer side and the inner side. For example, in some cases a particular configuration of yarns on the exposed outer side may be different from the configuration of yarns on the inner side. These differences can include, but are not limited to, one or more of: differences in knitting patterns, differences in knitted structures, differences in types of yarn used, differences in colors of yarns used, and/or differences in material properties of yarns used (e.g., different materials selected to provide a softer interior or inner side and a durable exposed outer side).
In some embodiments, a knitting configuration for an outer side may be provided to impart a greater degree of durability, strength, and/or wear or abrasion resistance to the exposed outer side of a knitted component 140. For example, a yarn having a heavier denier or being made of a stronger or more durable material may be used for the knitting configuration on the exposed outer side to provide a greater degree of durability, strength, and/or wear or abrasion resistance. Similarly, in some embodiments, a knitting configuration for an inner side may be provided to impart a greater degree of comfort or softness so as to serve as an interior lining of the upper 102. For example, a yarn having a lighter denier or being made of a material that is soft to the touch may be used for the knitting configuration on the interior or inner side to provide a greater degree of comfort or softness. With a desired selection of knitting configurations for each of an exposed outer side and an inner side of a knitted component, desired characteristics may be selectively provided to the upper.
FIGS. 2 to 6 illustrate schematic views of an embodiment of a knitted textile element including knitted components in a pre-removal state or condition. FIG. 2 is a schematic plan view of an embodiment of a knitted textile element 200 including knitted components 230 and 240, pre-removal, in which features of a warp knit stitch and an interlayer warp knit stitch line 214 of the knitted textile element are schematically shown in enlarged detail views 213 and 215, respectively. FIGS. 3 to 6 schematically illustrate knitted textile element 200 in rotational sequence from a medial isometric view to a lateral isometric view, where FIG. 3 is a medial isometric view, FIG. 4 is a medial isometric edge view, FIG. 5 is a lateral isometric edge view, and FIG. 6 is a lateral isometric view. It will be appreciated that FIGS. 3 to 6 are schematic views intended for illustrating certain features of the knitted textile element. FIGS. 2 to 6 illustrate knitted textile element 200 as a continuous knit layer (e.g., a tubular knitted textile element) to facilitate illustration and discussion of certain features, such as features along a common edge of a two-layer knitted textile element (FIGS. 4 and 5), and certain processes that may be used in some embodiments. In some embodiments, however, knitted textile element 200 may not have a general tubular configuration.
Knitted textile element 200 may be a knitting product of a warp knitting machine and warp knitting process. Knitted textile element 200 may be a generally flat, two-dimensional structure that includes a first layer 202 and a second layer 204 that overlays the first layer 202. In some embodiments, knitted textile element 200 may be formed as a tubular textile using a warp knitting machine having two sets of needles. In some embodiments, knitted textile element 200 may be warp knitted in a single knitting process that progresses in a feed direction of arrow 201. In some embodiments, knitted textile element 200 is of unitary warp knit configuration.
In the tubular configuration of FIGS. 2 to 6, first layer 202 and second layer 204 have a common, continuous first surface 206 that initially is exposed as a result of the warp knitting process, and a common second surface 208 that initially is not exposed as a result of the warp knitting process. In particular, exposed first surface 206 of first layer 202 and exposed first surface 206 of second layer 204 are continuous around an outside surface of common edge 210 of tubular knitted textile element 200. Likewise, initially non-exposed second surface 208 of first layer 202 and initially non-exposed second surface 208 of second layer 204 are continuous around an inside or interior side surface of common edge 210. As shown in FIGS. 2 to 6, in some embodiments initially exposed first surface 206 and initially non-exposed surface 208 also may be continuous around a second common edge 212 opposite common edge 210. In some embodiments, initially exposed first surface 206 and initially non-exposed surface 208 may be dis-continuous at second edge 212. It will be appreciated that the term common edge as used in this description refers to a generally continuous layer that transitions between opposite sides along a line or fold, for example by being turned back or folded back onto itself, that serves as a shared boundary or perimeter between the opposite sides to form the common edge, and that does not indicate a discontinuous surface or contour between the opposite sides.
Knitted textile element 200 includes an interlayer knit stitch line between the first layer 202 and second layer 204. For example, as shown in FIG. 2, in some embodiments knitted textile element 200 may include an interlayer knit stitch line 214 located at a periphery of knitted component 240, and an interlayer knit stitch line 232 located at a periphery of knitted component 230. FIG. 2 includes an enlarged schematic view 215 of interlayer knit stitch line 214 between first knit layer 202 and second knit layer 204 at a forefoot portion of knitted component 240. As shown at 215, interlayer knit stitch line 214 includes interlayer knitting stitches between first knit layer 202 and second knit layer 204, where at least one yarn of first knit layer 202 is interlooped with at least one yarn of second knit layer 204 at an interface of first knit layer 202 and second knit layer 204. In some embodiments, multiple yarns of first knit layer 202 and/or multiple yarns of second knit layer 204 may be interlooped at interlayer knit stitch line 214.
Knitted textile element 200 is a textile material from which knitted components 230 and 240 may be removed. Knitted components 230 and 240 may be removed by any known or later developed removal method. For example, knitted components 230 and 240 may be removed or separated by cutting, stamping, or any other method for separating the knitted component from the larger knitted textile element 200 or any excess material of knitted textile element 200. In some embodiments, knitted components 230 and 240 may be removed by separating the knitted components 230 and 240 from textile element 200 using a cutting process or other separating process along interlayer knit stitch line 214. It will be appreciated that, since first knit layer 202 and second knit layer 204 are interconnected along interlayer knit stitch line 214 and interlayer knit stitch line 232 using a warp knitting process, separating knitted textile element 200 along interlayer knit stitch lines 214 and 232 may not cause unravelling of knitted components 230 and 240 along a separated or cut edge.
FIGS. 3 to 6 illustrate a process for removing or separating knitted components 230 and 240 from knitted textile element 200 using optional knitted indicating portions. In some embodiments, knitted components 230 and 240 may be removed or separated from knitted textile element 200 using one or more optional knitted indicating portions. FIG. 3 illustrates a knitted indicating portion 310 provided around an outer periphery or outline of knitted component 230 corresponding to a tongue. FIG. 3 illustrates a knitted indicating portion 312 provided around an outer periphery or outline of knitted component 240 corresponding to a seamless bootie or textile upper, such as knitted component 140 of upper 102 shown in FIG. 1.
Knitted component 230 may be removed or separated from knitted textile element 200 by separating knitted textile element 200 along knitted indicating portion 310. Knitted component 240 may be removed or separated from knitted textile element 200 by separating knitted textile element 200 along knitted indicating portion 312. It will be appreciated that, since first knit layer 202 and second knit layer 204 are interconnected along interlayer knit stitch line 214 and interlayer knit stitch line 232 using a warp knitting process, separating knitted textile element 200 along knitted indicating portions 310 and 312 may not cause unravelling of knitted components 230 and 240 along the separated or cut edge. Moreover, providing knitted indicating portions 310 and 312 along an outer periphery of knitted components 230 and 240 may provide a controlled spacing between interlayer knit stitch lines 214 and 323 and respective separated or cut edges along knitted indicating portions 310 and 312. It will be appreciated that this controlled spacing may further assist in preventing any unravelling of knitted components 230 and 240 along their peripheral edges.
FIGS. 3 to 6 illustrate process for removing or separating knitted components from knitted textile element using a cutting tool 314, such as a knife. FIG. 3 illustrates a process of separating knitted component 240 from knitted textile element 200 by cutting first knit layer 202 of knitted textile element 200 along knitted indicating portion 312 to form separation or cut line 316. Similarly, FIG. 6 illustrates a process of separating knitted component 240 from textile element 200 by cutting second knit layer 204 of knitted textile element 200 along knitted indicating portion 312 to form separation or cut line 616. Since first knit layer 202 and second knit layer 204 are interconnected along interlayer knit stitch line 214, it will be appreciated that in some embodiments first knit layer 202 and second knit layer 204 may be separated or cut in a single simultaneous separating or cutting process.
FIGS. 4 and 5 illustrate processes for separating portions of knitted component 240 to form an opening in knitted component 240. FIG. 4 illustrates a knitted indicating portion 410 (illustrated as double dashed lines) located along common edge 210, and FIG. 5 illustrates a process of separating knitted component 240 along knitted indicating portion 410 using a cutting process to form separation or cut line 510, corresponding to an ankle opening of knitted component 240. Similarly, FIG. 5 illustrates a knitted indicating portion 512 (illustrated as double dashed lines), and FIG. 4 illustrates a process of separating knitted component 240 along knitted indicating portion 512 using a cutting process to form a separation or cut line 412 corresponding to an opening of a closure system. In some embodiments, as shown in FIGS. 4 and 5, knitted indicating portion 410 and/or knitted indicating portion 412 may be substantially formed along straight lines. In some embodiments, knitted indicating portion 410 and/or knitted indicating portion 412 may not be formed along a straight line, but may have regular or non-regular geometric configurations. For example, in some embodiments knitted indicating portion 410 may be a contoured curved line configured to provide a contoured ankle opening. In some embodiments, knitted indicating portion 412 may be a line having a scalloped configuration outlining a series of lacing members. In some embodiments, knitted indicating portion 410 and knitted indicating portion 412 may be continuous, and in some embodiments knitted component 240 may be separated along knitted indicating portions 410 and 412 in a single continuous cutting process or other separating process. In some embodiments, knitted indicating portion 412 may be optional (i.e., no closure structure). Those skilled in the art readily will appreciate various configurations for knitted indicating portions suitable for forming a desired ankle opening and any optional closure structure for a desired upper configuration.
In the configuration of FIGS. 2 to 6, knitted textile element 200 (and, accordingly, knitted components 230 and 240) has a generally flat, two-layer, two-dimensional configuration that comprises one or more yarns knitted together. In some embodiments, knitted textile element 200 may have a generally tubular configuration. In some embodiments, knitted textile element 200 may have an open or discontinuous configuration along a second common edge 212 of knitted textile element 200. In some embodiments, e.g., as disclosed in FIGS. 23 and 24 below, first layer 202 and second layer 204 may have a generally continuous interlayer knitting stitching over at least a portion of an area or region outside a periphery or outline of a knitted component.
Knitted component 240 may include various portions that correspond to portions or regions of a seamless bootie or textile upper 102 as shown in FIG. 1. For example, knitted component 240 may include a forefoot portion 242, a midfoot portion 244, and a heel portion 246 that may correspond to forefoot portion 142, midfoot portion 144, and heel portion 146, respectively, of knitted component 140 of upper 102 in FIG. 1. Likewise, for example, lateral side portion 248 may correspond to lateral side 148 of knitted component 140 of upper 102, and medial side portion 250 may correspond to medial side 150 of knitted component 140 of upper 102.
FIG. 7 is a schematic plan view of knitted component 230 of FIG. 2, post removal, corresponding to a tongue. Knitted component 230 is of unitary warp knit construction. In some embodiments, knitted component 230 may include a first knit layer 202, a second knit layer 204, and an interlayer knit stitch line 232 that defines a perimeter or outline of knitted component 230. Because knitted component 230 is of unitary warp knit construction defined at its perimeter by interlayer knit stitch line 232, knitted component 230 may have a stable knit construction that will not unravel at its perimeter edges when separated and removed from knitted textile element 200. Knitted component 230 may include a knitted indicating portion 234 indicating a separating line for creating an opening 236 in knitted component 230. In this manner, a void or pocket may be formed in an interior of knitted component 230. In some embodiments, knitted component 230 optionally may be turned inside out through opening 236. In this case an initially exposed external surface 206 of knitted component 230 may be interchanged with an initially non-exposed interior surface 208 of knitted component 230. In some embodiments, initially exposed surface 206 may have a different finish and/or aesthetic characteristic than initially non-exposed surface 208. In either case, an optional insert member (not shown), e.g., made of a foam material, may be inserted through opening 236 into an internal void or pocket formed between the first knit layer 202 and the second knit layer 204 of knitted component 230, to modify a cushioning characteristic of the tongue. Knitted component 230 may be provided with plurality of holes 238. In some embodiments, plurality of holes 238 may be provided in first knit layer 202 and in second knit layer 204. In some embodiments, plurality of holes 238 may be optionally provided in either first knit layer 202 or second knit layer 204. Plurality of holes 238 may be formed by knitting process or by separating knitted component 230, e.g., at knitted indicating portions corresponding to plurality of holes 238. It will be appreciated that plurality of holes 238 may provide improved general and/or local ventilation characteristic. Plurality of holes 238 also may provide a desired aesthetic characteristic.
FIG. 8 is a schematic plan view of a knitted component 240 of FIG. 2, post removal, corresponding to a seamless bootie or textile upper of an article of footwear. For example, in some embodiments knitted component 240 may correspond to knitted component 140 of upper 102 in FIG. 1. Knitted component 240 is of unitary warp knit construction. Knitted component 240 generally includes first knit layer 202 forming a medial side of knitted component 240 and second knit layer 204 forming a lateral side of knitted component 240. First knit layer 202 and second knit layer 204 of knitted component 240 are continuous across forefoot portion 242, including common edge portion 210. Knitted component 240 includes an interlayer knit stitch line 214 that interconnects first knit layer 202 and second knit layer 204 along a peripheral portion of knitted component 240. In some embodiments, as shown in FIGS. 2 and 8, interlayer knit stitch line 214 may extend around a front toe portion 254 of knitted component 240, across a bottom portion 256 of knitted component 240, and around heel portion 246 of knitted component 240.
Knitted component 240 may have an ankle opening 810 that is defined by edges 216, corresponding to knitted indicating portion 410 and separation line 510, and a closure structure 221 that is defined by edges 218, corresponding to knitted indicating portion 412 and separation line 512. In some embodiments, closure structure 221 may include lacing members 222 and eyelet holes 224. Lacing members 222 may include reinforced structure of knitted component 240 produced by a knitting configuration or yarn selected to provide a strong, durable textile characteristic. A specific configuration of closure structure 221, e.g., including lacing members 222 and eyelet holes 224, may be provided by selecting a knitting configuration of knitted component 240. For example, in some embodiments an eyelet hole 224 may be formed by selecting a knitting configuration of knitted component 240 including a knitted hole having a desired size and shape. Alternatively, in some embodiments a knitting configuration for an eyelet hole 224 may include a knitted indicating portion that indicates a location for separating knitted component 240 to form eyelet hole 224.
In some embodiments, knitted component 240 as removed or separated from knitted textile element 200 may be directly manipulated or stretched to form a seamless bootie or textile upper in its final form. In some embodiments, however, prior to being manipulated or stretched to form a final seamless bootie or textile upper, knitted component 240 may be inverted, or turned inside-out, to present an alternative finish surface for the seamless bootie or textile upper.
FIGS. 9 to 13 schematically illustrate an optional inversion process for a knitted component 240 of FIG. 8 (i.e., for turning knitted component 240 inside-out post removal). Because knitted component 240 is formed of a unitary warp knit construction, including an exposed peripheral edge that is defined in part by separating (e.g., cutting) along interlayer knit stitch line 214, knitted component 240 generally provides a stable knit construction that will not unravel at the separated peripheral edge. Nevertheless, in some embodiments knitted component 240 may be inverted to interchange the initially exposed exterior surface 206 of the first and second layers 202 and 204 and the initially non-exposed interior surface 208 to present a clean (i.e., unseparated or uncut) portion of the interlayer knit stitch line 214 as an exterior peripheral surface of knitted component 240. As noted above, in some embodiments the initially exposed exterior surface 206 and the initially non-exposed interior surface 208 may have different finishes or other characteristics. Inverting knitted component 240 enables presentation of an initially non-exposed interior surface 208 as a final exposed external surface of knitted component 240 (and resulting article of footwear 100).
FIG. 9 illustrates knitted component 240 in an initial post removal state. For purposes of distinguishing the two surface in this description, in FIGS. 9-13 initially exposed exterior surface 206 is shown without substantial shading and initially non-exposed internal surface 208 is shown with substantial shading. In some embodiments, initially exposed external surface 206 and initially non-exposed internal surface 208 may have same or similar characteristics. In some embodiments, initially exposed external surface 206 and initially non-exposed internal surface 208 may have substantially different characteristics.
FIG. 10 illustrates knitted component 240 with front toe portion 254 inverted, i.e., front toe portion 254 is shown in phantom to schematically illustrate that front toe portion 254 is pushed into an internal void or space between first knit layer 202 and second knit layer 204 of knitted component 240, as indicated by arrow 1010.
FIG. 11 illustrates knitted component 240 with an inverted front toe portion 254 being pulled through ankle opening 810, as indicated by arrow 1110, and heel portion 246 being pushed forward over front toe portion 254, as indicated by arrow 1112.
FIG. 12 illustrates knitted component 240 with front toe and forefoot portions 254, 242 protruding through, and being pulled through ankle opening 810, as indicated by arrow 1210, and heel portion 246 being pushed down over front toe portion 254 and forefoot portion 242, as indicated by arrow 1212. In FIG. 12, the inversion process is substantially complete.
FIG. 13 illustrates knitted component 240 fully inverted, i.e., turned inside-out from its initially removed or separated state. As schematically illustrated by multiple shading in FIGS. 9 to 13, knitted component 240 may have substantially different finish and aesthetic characteristics on the initially exposed external surface (final internal surface) 206 and the initially non-exposed internal surface (final exposed outside surface) 208. In some embodiments, different shading may represent different knitting stitches, such as a loose or tight knitting configuration. In some embodiments, different shading may represent different size or shape of holes, such as large or small knitted holes. In some embodiments, different shading may represent different aesthetic characteristics. In some embodiments, different shading may represent different knitting stitches corresponding to different knitted indicating portions. In some embodiments, different shading may represent different yarn material(s). In some embodiments, different shading may represent different yarn or textile fabric treatment(s), such as yarns treated with a substance that enables material memory and untreated yarns. Those skilled in the art readily will appreciate that, in this manner, any desired surface characteristics may be indicated and provided on either an exposed external surface or an internal surface.
FIGS. 14 to 18 schematically illustrate an embodiment of an article of footwear 100 in the form of a seamless bootie or textile upper 1440. In some embodiments, seamless bootie or textile upper 1440 may correspond to knitted 140 of FIG. 1 or knitted component 240 of FIGS. 2 and 8. FIGS. 14 to 16 illustrate a seamless bootie or textile upper 1440 in rotational sequence from a medial isometric view (FIG. 14), to a bottom isometric plan view (FIG. 15), to a lateral isometric view (FIG. 16); FIG. 17 is a schematic isometric bottom front view of the textile upper; and FIG. 18 is a schematic isometric top front view of the textile upper.
In some embodiments, knitted component 240 may be manipulated to form seamless bootie or textile upper 1440 having a desired configuration, at least including size and shape. In some embodiments, one or more portions of knitted component 240 may be stretched to form seamless bootie or textile upper 1440 having a desired configuration, at least including size and shape. In some embodiments, knitted component 240 may be stretched over a last corresponding to a seamless bootie or textile upper 1440 having a desired size and shape generally corresponding to either a particular foot or a standard foot size. For example, the last may have a desired length, width, girth, and/or volume.
Knitted component 240 may include one or more portions or zones having knitting stitches or a knitting configuration selected to enable the portion to stretch to a desired configuration for seamless bootie or textile upper 1440. For example, in some embodiments a portion or zone of knitted component 240 may be provided with plurality of holes in a stretch zone. In some embodiments, knitted component 240 may include a portion or zone that has loose knitting stitches or a loose knitting configuration to form a stretch zone. In some embodiments, a stretch zone of knitted component 240 may be configured to stretch more than other portions of knitted component 240, i.e., relatively more than other portions of knitted component 240, to facilitate forming the knitted component 240 into seamless bootie or textile upper 1440 having a desired size and shape. In some embodiments, a bottom portion 256 may be a stretch zone.
In FIGS. 14 to 18, knitted component 240 may be provided with a stretch zone 1402 (shown in dark shading). In some embodiments, stretch zone 1402 may be configured to stretch more than some other portions of knitted component 240, such as zone 1404 corresponding to a central bottom portion of seamless bootie or textile upper 1440, while stretching less than some other portions or zones of knitted component 240, such as portions or zones corresponding to plurality of holes 1406 and 1408. For example, corresponding portions 1502 and 1504 (shown with dark shading) of first knit layer 202 and second knit layer 204 of knitted component 240, respectively, may be provided so as to form generally continuous annular stretch zone 1402 around a perimeter of the central bottom portion 256 of knitted component 240. This configuration may facilitate knitted component 240 being stretched to form an asymmetric configuration having a generally symmetrical central bottom portion 256, e.g., having a first material characteristic, and an asymmetrical peripheral base or bottom portion (e.g., stretch zone 1402), having a second material characteristic. In some embodiments, central base portion 256 and peripheral stretch zone 1402 together may generally correspond to a size and shape of a foot, i.e., a foot print, and/or a shape of a sole. The second material characteristic may be different than the first material characteristic (e.g., in addition to a different degree of stretching). It will be appreciated that with this construction a knitted component 240 may be stretched in different ways to achieve one of at least two different possible desired final configurations for seamless bootie or textile upper 1440. For example, knitted component 240 could be stretched to form either a right article of footwear or a matching left article of footwear by controlling a relative amount of stretching of various portions of stretch zone 1402. Alternatively, knitted component 240 could be stretched to form an article of footwear having any one of a narrow, medium, or wide finished width by controlling an amount of stretching of stretch zone 1402. It further will be appreciated that this construction and configuration, including a central base portion 256 and a peripheral stretch zone 1402, may facilitate bonding of seamless bootie or textile upper 1440 to a sole structure having a similar right vs. left foot configuration, and/or a particular size or width.
In some embodiments, knitted component 240 may be treated with a substance for facilitating or enabling material memory upon stretching knitted component 240 to a desired size and shape. For example, in some embodiments, one or more yarns made of a material having inherent material memory may be used in a knitting process for knitting knitted component 240. In some embodiments, one or more yarns of knitted component 240 may be pre-treated with a substance for enabling material memory prior to the knitting process. In some embodiments, at least one portion of a knitted textile element 200 corresponding to at least one portion of knitted component 240 may be pre-treated with a substance for enabling material memory prior to removing knitted component 240 from knitted textile element 200. In some embodiments, portions of knitted component 240 may be treated with a substance for enabling material memory prior to stretching knitted component 240 over a last. In some embodiments, at least a portion of seamless bootie or textile upper 1440 may be treated with a substance for enabling material memory during or after stretching on a last. Examples of substances for enabling material memory include, but are not limited to a thermoplastic polyurethane (TPU) coating, TPU-based coatings, and/or other solutions incorporating TPU. Those skilled in the art readily will be able to select treated yarns, substances, and treatment protocols for facilitating or enabling material memory suitable for achieving a seamless bootie or textile upper 1440 for a desired application.
In some embodiments, knitted component 240 may be heat treated to enable forming the knitted component. For example, knitted component 240 may be heat treated in association with stretching over a last. In some embodiments, knitted component 240 may be heat treated prior to stretching over a last. In some embodiments, knitted component 240 may be heat treated while stretched over a last. In some embodiments, knitted component 240 may be heat treated after removal from a last. In some embodiments, one or more of these heat treatments may be used together. In each case, heat treating a knitted component 240 may facilitate forming the knitted component by stretching one or more portions of knitted component 240 to a desired size, shape, or configuration.
In some embodiments, knitted component 240 may be treated with a substance for facilitating or enabling material memory and heat treated to facilitate forming seamless bootie or textile upper 1440 with a desired size and shape, with material memory.
As shown in FIGS. 15 and 17, after forming by manipulating and/or stretching, a width 1510 of a portion of stretch zone 1502 on a medial side of seamless bootie or textile upper 1440 may be different than a width 1512 of a corresponding portion of the stretch zone 1504 on a lateral side of the seamless bootie or textile upper 1440.
As shown in FIGS. 15 and 17, after forming by manipulating and/or stretching knitted textile 240, a location of interlayer knit stitch line 214 between first knit layer 202 and second knit layer 204 of knitted component 240 may become asymmetrical with respect to medial and lateral sides 248 and 250 of seamless bootie or textile upper 1440. For example, as shown in bottom plan view in FIG. 15, interlayer knit stitch line 214 may have a gentle S-shaped curve that generally follows a contour of the central bottom portion 256 of seamless bootie or textile upper 1440.
As shown in FIGS. 16 and 18, because knitted component 240 is of unitary warp knit construction, with a continuous layer at forefoot portion 242, seamless bootie or textile upper 1440 may have continuous knitting stitch and/or knitting configuration, presenting an aesthetically pleasing appearance at forefoot portion 242. For example, as shown in FIGS. 16 and 18, knitted component 240 may have plurality of holes 1406 having a continuous hole pattern across an entirety of forefoot portion 242, such as a plurality of continuous, parallel, in-line arrays of holes.
As shown in FIGS. 17 and 18, after forming by manipulating and/or stretching knitted component 240, a location of interlayer knit stitch line 214 may extend at least partly around (wrap around) a front toe portion 254 of seamless bootie or textile upper 1440. In some embodiments, knitted component 240 may be inverted (i.e., turned inside-out) so that interlayer knit stitch line 214 is substantially hidden on an interior surface of seamless bootie or textile upper 1440. In some embodiments, however, knitted component 240 may not be inverted and interlayer knit stitch line 214 may be present on an exposed exterior surface at front toe portion 254 of seamless bootie or textile upper 1440. In this case, interlayer knit stitch line 214 still presents a substantially continuous and stable knitted surface at front toe portion 254 of seamless bootie or textile upper 1440. In some embodiments, at least a portion of exposed interlayer knit stitch line 214 at front toe portion 254 may be covered by a sole structure or other finishing treatment.
Seamless bootie or textile upper 1440 may provide an article of footwear 100 without substantial further modification or manufacture. In some embodiments, seamless bootie 1440 may form an article of footwear 100 without any further modification or manufacture. In some embodiments, seamless bootie or textile upper 1440 may form an article of footwear by applying a finishing treatment or process to at least a portion of the bootie. In some embodiments, a finishing treatment may be applied to a bottom surface portion of the bootie to provide durability and/or traction. Examples of such applied or finishing treatment may include, but are not limited to, applying a layer of grip material or direct injection of a grip material, such as a rubber. It will be appreciated that providing seamless bootie or textile upper 1440 with a finishing treatment or process also may provide reinforcing properties to interlayer knit stitch line 214. In some embodiments, providing seamless bootie or textile upper 1440 with a finishing treatment may inject or infuse bonding agent between yarns of first knit layer 202 and second knit layer 204 at interlayer knit stitch line 214 to bind or bond exposed yarn ends or otherwise loose yarn(s) at interlayer knit stitch line 214. Such seamless bootie or textile upper 1440 may form an article of footwear suitable for various activities such as wrestling, dance, aerobic exercise, rock wall climbing, or other activities that use light weight footwear having no separate sole structure assembly.
In some embodiments, seamless bootie or textile upper 1440 may form an article of footwear by adding one or more accessories, such as a tongue or insert member. FIG. 19 is a schematic isometric top front view of an embodiment of an article of footwear 1900 incorporating a seamless bootie or textile upper 1440 of FIGS. 14 to 18, an optional tongue 1930, and an optional sole structure 1904. FIG. 20 is a schematic isometric rear view of article of footwear 1900 of FIG. 19.
Tongue 1930 may be formed from a knitted component. For example, tongue 1930 may correspond to knitted component 230, as shown in FIGS. 2 and 7. As shown in FIG. 19, tongue 1930 may be disposed within an interior space of seamless bootie or textile upper 1440. Tongue 1930 may be configured to be located between a closure structure 221 of seamless bootie or textile upper 1440 and a wearer's foot. Tongue 1930 may be associated with closing region 221 by attaching a front edge of tongue 1930 to seamless bootie or textile upper 1440 adjacent forefoot portion 242 of knitted component 240. Tongue 1930 may include plurality of holes 1910. Tongue 1930 may include an insert member (not shown), such as foam material, disposed between first and second knit layers. Tongue 1930 may be attached to seamless bootie or textile upper 1440 by any suitable known or later developed attaching method, such as by adhesive, thermal bonding, stitching, or other attaching mechanism.
Sole structure 1904 may be any suitable known or later developed sole structure. In some embodiments, as shown in FIG. 19, sole structure 1904 may include front toe portion 1906 that covers at least a portion of interlayer knit stitch line 214 (illustrated in phantom as double dashed lines for purposes of description) located at front toe portion 254 of seamless bootie or textile upper 1440. In some embodiments, sole structure 1904 may wrap around at least part of front toe portion 254 and cover substantially all or an entirety of interlayer knit stitch line 214 at front toe portion 254 (see, e.g., FIG. 1). Sole structure 1904 may be associated with seamless bootie or textile upper 1440 by any suitable known or later developed attaching method, such as by adhesive or other bonding method. It will be appreciated that attaching seamless bootie or textile upper 1440 to sole structure 1904 may provide reinforcing properties to interlayer knit stitch line 214. In some embodiments, attaching by adhesive or other bonding method may infuse adhesive or bonding agent between yarns of first knit layer 202 and second knit layer 204 at interlayer knit stitch line 214 to bind or bond any exposed ends or otherwise loose yarn(s) at interlayer knit stitch line 214.
As shown in FIG. 20, interlayer knit stitch line 214 (shown in double dashed phantom lines for purposes of description) of knitted component 240 generally may be located along a central line between a medial side 250 and a lateral side 248 of knitted component 240 of seamless bootie or textile upper 1440. It will be appreciated that, because knitted component 240 is of unitary warp knit construction, including interlayer knit stitch line 214, knitted component 240 may present a substantially continuous knitting stitch and/or knitting configuration across heel portion 246 of seamless bootie or textile upper 1440. In some embodiments, knitted component 240 may include plurality of holes 2010 having a hole pattern that is substantially continuous across an entirety of heel portion 246. For example, as shown in FIG. 20, plurality of holes 2010 may include a plurality of substantially continuous, parallel, in-line arrays of holes across an entirety of heel portion 246, including interlayer knit stitch line 214. It will be appreciated that this construction may provide a pleasing aesthetic characteristic.
FIG. 21 schematically maps features of an embodiment of a knitted component 2140 of a knitted textile element 2100, pre-removal, to a seamless bootie or textile upper formed from knitted component 2140 post removal. In some embodiments, knitted textile element 2100 may correspond to knitted textile element 200 of FIG. 2, and knitted component 2140 may correspond to knitted component 240 of FIGS. 2 and 8 and/or knitted component 140 of FIG. 1.
In FIG. 21, reference number 2101 identifies a figure of knitted textile element 2100 (hereafter referred to as reference figure 2101) and includes a sequence of section lines 2111-2119 that schematically map various features and characteristics of knitted component 2140 of knitted textile element 2100 across corresponding figures at reference numbers 2102, 2103, 2104, and 2105 (hereafter referred to as reference figures 2102, 2103, 2104, and 2105). Reference figure 2102 illustrates a sequence of cross-sectional views 2121 to 2129 associated with knitted component 2140 of knitted textile element 2100 taken along section lines 2111 to 2119; reference figure 2103 illustrates a medial side view of knitted component 2140; reference figure 2104 illustrates a bottom plan view of knitted component 2140; and reference figure 2105 illustrates a lateral side view of knitted component 2140.

Section line 2111 passes through knitted textile element 2100 above knitted component 2140, outside a peripheral boundary of knitted component 2140 defined by interlayer knit layer 2150. Accordingly, mapping section line 2111 in reference figure 2101 to reference figure 2102 presents a cross-section of knitted component 2100 in the form of a tubular structure 2121 having no physical features associated with knitted component 2140. Likewise, reference figures 2103, 2104, and 2105 present no physical features associated with knitted component 2140 along section line 2111.
Section line 2112 passes through a rear heel portion of knitted component 2140. Mapping section line 2112 in reference figure 2101 to reference figure 2102 presents a cross-section of knitted textile element 2100 in the form of a generally flattened tubular structure 2122 having a single node where interlayer knit stitch line 2150 interconnects first knit layer 2152 and second knit layer 2154 at a distance 2130 from common side edge 2156 of knitted textile element 2100 (see, e.g., common side edge 210 in FIGS. 2 to 6).

Mapping reference figure 2101 to reference figure 2104, illustrating a bottom view of a seamless bootie or textile upper formed from knitted component 2140, it will be appreciated that along section line 2114 a distance 2133 from common edge 2156 of knitted component 2140 to an edge of central bottom portion 2160 and a distance 2134 from the edge of the central bottom portion 2160 to the interlayer knit stitch line 2150 corresponds to the distance 2132 from the common edge 2156 to the interlayer knit stitch line 2150 (distance 2133+distance 2134=distance 2132), and a distance 2146, corresponding to a width of central bottom portion 2160 along section line 2114, equals two times the distance 2134 (distance 2146=2×distance 2134). Similarly, a distance 2147, corresponding to a width of central bottom portion 2160 and peripheral bottom portion 2162 of knitted component 2140 along section line 2114, equals two times the distance 2135 between an edge of peripheral bottom portion 2162 and the interlayer knit stitch line 2150 along section line 2114 (distance 2147=2×distance 2135).
Section line 2115 passes through a midfoot portion of knitted component 2140 at an end of closure system 2170 proximate to forefoot portion 2158. Mapping section line 2115 in reference figure 2101 to reference figure 2102 presents a cross-section of knitted textile element 2100 in the form of a flattened tubular structure 2125 having a single node where interlayer knit stitch line 2150 interconnects first knit layer 2152 and second knit layer 2154 at a distance 2136 from common side edge 2156 of textile element 2100. Mapping reference figure 2101 to reference figure 2104 along section line 2115, it will be appreciated that a distance 2137 from common edge 2156 of knitted component 2140 to an edge of central bottom portion 2160 and a distance 2138 from the edge of central bottom portion 2156 to the interlayer knit stitch line 2150 corresponds to the distance 2136 from common edge 2156 to interlayer knit stitch line 2150 (distance 2137+distance 2138=distance 2136), and a distance 2148, corresponding to a width of the central bottom portion 2160 along section line 2115, equals two times the distance 2138 along section line 2115. Similarly, a distance 2149, corresponding to a width of central bottom portion 2160 and peripheral bottom portion 2162 along section line 2115 equals two times the distance 2139 between an edge of peripheral bottom portion 2162 and the interlayer knit stitch line 2150 along section line 2115 (distance 2149=2×distance 2139).
Section line 2116 passes through forefoot portion 2158 of knitted component 2140. Mapping section line 2116 in reference figure 2101 to reference figure 2102 presents a cross-section of knitted textile element 2100 in the form of a flattened tubular structure 2126 having a single node where interlayer knit stitch line 2150 interconnects first knit layer 2152 and second knit layer 2154 at a distance 2141 from common side edge 2156 of textile element 2100.
Section line 2117 also passes through forefoot portion 2158 of knitted component 2140. Mapping section line 2117 in reference figure 2101 to reference figure 2102 presents a cross-section of knitted textile element 2100 in the form of a tubular structure 2127 having a first node where interlayer knit stitch line 2150 interconnects first knit layer 2152 and second knit layer 2154 at a distance 2142 from common side edge 2156 of textile element 2100, and a second node where interlayer knit stitch line 2150 interconnects first knit layer 2152 and second knit layer 2154 at a distance 2143 from the first node of textile element 2100 along section line 2117.
Section line 2118 touches and extends tangentially with a front edge of forefoot portion 2158 of knitted component 2140. Mapping section line 2118 in reference figure 2101 to reference figure 2102 presents a cross-section of knitted textile element 2100 in the form of a flattened tubular structure 2128 having a single node where interlayer knit stitch line 2150 interconnects first knit layer 2152 and second knit layer 2154 at a distance 2144 from common edge 2156 of textile element 2100.
Section line 2119 passes through knitted textile element 2100 below knitted component 2140, outside a peripheral boundary of knitted component 2140 defined by interlayer knit stitch line 2150. Accordingly, mapping section line 2119 in reference figure 2101 to reference figure 2102 presents a cross-section of knitted textile element 2100 in the form of a flattened tubular structure 2129 having no physical features associated with knitted component 2140. Likewise, reference figures 2103, 2104, and 2105 present no physical features associated with knitted component 2100 and section line 2119.
It will be appreciated that dimensions of knitted textile element 2100 and knitted component 2140 may be selected to provide desired configuration (size and shape), custom fit, and performance characteristics in a seamless bootie or textile upper formed from knitted component 2140.
For example, it will be appreciated that distance 2131 corresponds to a greatest width of knitted textile component 2140, and that distance 2131 thus represents a minimum width of knitted textile element 2100 sufficient to define and make knitted component 2140. Accordingly, in some embodiments a width of knitted textile element 2100 may be selected to substantially equal distance 2131 to minimize an amount material and cost required for making knitted textile element 2100 and knitted component 2140.
Selecting dimensions 2132, 2133, 2134, and 2135 (e.g., at an end of closure system 2170 proximate the ankle opening of knitted component 2140) and dimensions 2136, 2137, 2138, and 2139 (e.g., at an end of closure system 2170 proximate forefoot portion 2158) may provide a desired size and/or custom fit of a seamless bootie or textile upper formed from knitted component 2140. A desired custom fit of the seamless bootie further may be facilitated by selecting a configuration of closure system 2170. For example, providing a V-shaped closure structure 2170 (see, e.g., FIG. 1) with such selected dimensions at an end of closure structure 2170 proximate forefoot portion 2158 may provide a desired size and/or custom fit at that location (e.g., girth), and facilitate further custom fit by facilitating precise tightening tolerances of a lacing system of closure system 2170.
Selecting similar dimensions at other locations of knitted component 2141, such as along section lines 2111 to 2119, similarly may provide a desired sizing and/or custom fit of knitted component 2141 at such locations. For example, selecting dimensions 2141, 2142, and 2143 at forefoot portion 2158 may provide a toe box having a desired sizing and/or custom fit.
Those skilled in the art readily will be able to select dimensions for knitted component 2140 suitable to provide desired sizing and/or a custom fit of a seamless bootie or textile upper formed from knitted component 2140.
Reference figures 2106 to 2109 illustrate further features of a seamless bootie or textile upper formed from knitted component 2140. Reference figure 2106 is a front perspective view of a seamless bootie or textile upper formed from knitted component 2140.
Reference figure 2107 illustrates a cross-section of forefoot portion 2158 taken along section line 2107-2107 in reference figure 2106. In some embodiments, as shown in reference figure 2107, first knit layer 2152 and second knit layer 2154 form a single continuous generally annular (tubular) knitted layer at forefoot portion 2158. In particular, as shown in reference figure 2108, which is an enlarged detail view at interlayer knit stitch line 2150, first knit layer 2152 and second knit layer 2154 provide a continuous knitted layer at interlayer knit stitch line 2150. As shown in reference figure 2108, interlayer knit stitch line 2150 includes at least one yarn of first knit layer 2152 interlooped with at least one yarn of second knit layer 2154. This continuous knitted structure at interlayer knit stitch line 2150 may help prevent unravelling of knitted component 2140 at interlayer knit stitch line 2150. As schematically illustrated in reference figure 2108, post separation or removal of knitted component 2140 from knitted textile element 2100 along interlayer knit stitch line 2150, a small amount of terminal yarn ends resulting from a separating process may be exposed at interlayer knit stitch line 2150. In some embodiments, where knitted component 2140 is inverted prior to forming a seamless bootie or textile upper, exposed yarn ends at interlayer knit stitch line 2150 may be located on an interior side of the seamless bootie or textile upper (as shown in reference figure 2108). In some embodiments, where knitted component 2140 is not inverted prior to forming a seamless bootie or textile upper, exposed yarn ends at interlayer knit stitch line 2150 may be located on an exterior side of the seamless bootie or textile upper.
Reference figure 2109 illustrates a cross-section of a seamless bootie or textile upper taken along section line 2109-2109 in reference figure 2106. In some embodiments, as shown in reference figure 2106, the seamless bootie or textile upper may include a closure system 2170 formed in knitted component 2140 by a separating process, such as shown in FIGS. 3-6. In some embodiments, closure system 2170 may include closure members 2172, eyelets 2174, and lacing 2176. In some embodiments, as shown in reference figure 2109, first knit layer 2152 and second knit layer 2154 form a single continuous knitted layer, where one end of first knit layer 2152 terminates as a knitted closure member 2172 on one side of closure structure 2170, and one end of second knit layer 2154 terminates as a knitted lacing member 2172 on an opposing side of closure structure 2170.
FIG. 22 illustrates a process flow chart 2200 including processes for making an article of footwear using a knitting method according to features of FIGS. 2 to 21. Process 2201 includes knitting a knitted textile element of a unitary warp knit construction. Process 2202 includes removing a knitted component from the knitted textile element. Optional process 2203 includes inverting the knitted component, i.e., turning the knitted component inside out. Process 2204 includes forming the knitted component into a seamless bootie or textile upper for an article of footwear. And optional process 2205 includes associating the seamless bootie or textile upper with one or more additional components, such as a sole structure, a tongue, or an overlay component. Option process 2205 also may include applying a finishing treatment, such as applying a grip material to a bottom surface of a seamless bootie. Those skilled in the art readily will be able to select desired processes for achieving an article of footwear consistent with this description of embodiments.
FIG. 23 is a schematic plan view of another embodiment of a knitted textile element including knitted components, pre-removal, in which features of a warp knit stitch and interlayer knit stitch line of the knitted textile element are shown in detail. FIG. 23 is substantially similar to FIG. 2. Accordingly, the description of features in FIG. 2 is incorporated by reference herein, and this description will be directed to features that may be different in FIG. 23.
FIG. 23 illustrates a knitted textile element 2300 of unitary warp knit configuration including a first knit layer 202 and a second knit layer 204 that overlays first knit layer 202 and that is continuous with first knit layer 202 along common edge 210. In some embodiments, knitted textile element 2300 may include a knitted component 230, corresponding to a tongue, and a knitted component 240, corresponding to a seamless bootie or textile upper. Knitted component 230 and knitted component 240 generally may include features corresponding to knitted component 230 and knitted component 240 as illustrated in FIG. 2 and described above. In FIG. 23, knitted textile element 2300 may include an interlayer knit stitch line 214 interconnecting first knit layer 202 and second knit layer 204 at a peripheral portion of knitted component 240, and an interlayer knit stitch line 232 interconnecting first knit layer 202 and second knit layer 204 at a peripheral portion of knitted component 240.
In some embodiments, however, as shown in FIG. 23, first knit layer 202 and second knit layer 204 of knitted textile element 2300 may be interconnected throughout an interlayer knitted portion 2310 outside a peripheral portion of knitted components 230 and 240 (illustrated by common continuous shading in FIG. 23). For purposes of description, FIG. 23 includes enlarged element 2315 schematically illustrating in cross-section a knitting configuration of knitted textile element 2300 including interlayer knit stitch line 214 and interlayer knitted portion 2310. As schematically illustrated in element 2315, first knit layer 202 and second knit layer 204 may be interconnected throughout interlayer knitted portion 2310 by a plurality of common knitting stitches in which at least one yarn of first knit layer 202 is interlooped with at least one yarn of second knit layer 204. In some embodiments, a plurality of common interlayer knitting stitches may include a series of individual interlayer knitting stitches using different yarns. In some embodiments, a plurality of common interlayer knitting stitches may include a series of interlayer knitting stitches using a common yarn. In some embodiments, as shown at element 2315, interlayer knitted portion 2310 may be contiguous with interlayer knit stitch line 214 between first knit layer 202 and second knit layer 204. In some embodiments, interlayer knitted portion 2310 may be continuous with interlayer knit stitch line 214 between first knit layer 202 and second knit layer 204. In some embodiments, interlayer knitted portion 2310 may include interlayer knit stitch line 214.
It will be appreciated that, in some embodiments knitted textile element 2300, including interlayer knitted portion 2310, may provide improved dimensional stability for knitted components 230 and 240, pre-removal. In some embodiments, textile element 2300 including interlayer knitted portion 2310 may facilitate improved handling during manufacturing processes. In some embodiments, textile element 2300 including interlayer knitted portion 2310 may facilitate removal of knitted components 230 and 240 using a single separation process for both first knit layer 202 and second knit layer 204, that is, a single process for separating a knitted component from first knit layer 202 and second knit layer 204.
FIG. 24 schematically maps features of an embodiment of a knitted component 2440 of a knitted textile element 2400, pre-removal, to a seamless bootie or textile upper formed from the knitted component 2440. FIG. 24 is substantially similar to FIG. 21. In some embodiments, textile element 2400 may correspond to textile element 2300 of FIG. 23, and knitted component 2440 may correspond to knitted component 2140 of FIG. 21. Accordingly, description of features previously described in connection with FIGS. 21 and 23 will not be repeated, and this description will be directed to features that may be different in FIG. 24.
In FIG. 24, features relating to knitted component 2440 are substantially similar to features of knitted component 2140 in FIG. 21. Reference figures 2401 to 2409 are substantially similar to reference figures 2101 to 2109. Section lines 2411 to 2419 in FIG. 24 correspond to section lines 2111 to 2119 in FIG. 21.
Section line 2411 passes through knitted textile element 2400 above knitted component 2440, outside a peripheral boundary of knitted component 2440 defined by interlayer knit layer 2450. In some embodiments, this construction may correspond to interlayer knitted portion 2310 in FIG. 23. Accordingly, mapping section line 2411 in reference figure 2401 to reference figure 2402 presents a cross-section of knitted component 2400 in the form of a flat two-layer structure 2421.

In some embodiments, as shown in reference figure 2407, first knit layer 2452 and second knit layer 2454 form a single continuous generally annular (tubular) knitted layer at forefoot portion 2458. In particular, as shown in reference figure 2408, which is an enlarged detail view at interlayer knit stitch line 2450, first knit layer 2452 and second knit layer 2454 provide a continuous knitted layer at interlayer knit stitch line 2450. As shown in reference figure 2408, interlayer knit stitch line 2450 includes at least one yarn of first knit layer 2452 interlooped with at least one yarn of second knit layer 2454. Moreover, as shown in figure 2408, it will be appreciated that in some embodiments interlayer knit stitch line 2450 may be separated at contiguous interlayer knitted portion 2310. This continuous knitted structure at interlayer knit stitch line 2450 and interlayer knitted portion 2310 may help prevent unravelling of knitted component 2440 at interlayer knit stitch line 2450. As schematically illustrated in reference figure 2408, post separation or removal of knitted component 2440 from knitted textile element 2400 along interlayer knit stitch line 2450 at interlayer knitted portion 2310, a small amount of terminal yarn ends resulting from a separating process may be exposed at interlayer knit stitch line 2450. In some embodiments, where knitted component 2440 is inverted (i.e., turned inside-out) prior to forming a seamless bootie or textile upper, exposed yarn ends at interlayer knit stitch line 2450 may be located on an interior side of the seamless bootie or textile upper (as shown in reference figure 2408). In some embodiments, where knitted component 2440 is not inverted prior to forming a seamless bootie or textile upper, exposed yarn ends at interlayer knit stitch line 2450 may be located on an exterior side of the seamless bootie or textile upper.
Reference figure 2409 illustrates a cross-section of a seamless bootie or textile upper taken along section line 2409-2409 in reference figure 2406.

In some embodiments, closure system 2470 may include lacing members 2472, eyelets 2474, and lacing 2476. In some embodiments, as shown in reference figure 2409, first knit layer 2452 and second knit layer 2454 form a single continuous knitted layer, where one end of first knit layer 2452 terminates as a knitted closure member 2472 on one side of closure structure 2470, and one end of second knit layer 2454 terminates as a knitted closure member 2472 on an opposing side of closure structure 2170.
Seamless Bootie or Textile Upper with Tucked-in Portions Article of Footwear Configurations
This section of the detailed description generally describes embodiments of methods for knitting a knitted textile element including a knitted component having tucked-in portions for incorporating into an upper for an article of footwear. Specifically, this section generally describes embodiments of methods for knitting a knitted textile element including a first knitted component portion that is configured to form a seamless bootie or textile upper and a second knitted component portion that is configured to be tucked-in or folded into an interior pocket of the seamless bootie or textile upper (i.e., the first knitted component portion), where the interior pocket is formed by the first knit layer and the second knit layer of the knitted textile element, and where the tucked-in portion (i.e., the second knitted component portion) is seamlessly associated with the first knit layer and the second knit layer of the seamless bootie or textile upper (i.e., the first knitted component portion) at an opening of the seamless bootie or textile upper that is configured to receive a foot. In some embodiments a tucked-in portion may form a dynamic fit structure of the article of footwear. In some embodiments a tucked-in portion may form a closure structure of the article of footwear, such as a gusseted tongue. In some embodiments, a tucked-in portion may include a pocket formed by the first knit layer and/or the second knit layer for receiving an insert member. In some embodiments, a tucked-in portion may cooperate with one of the first knit layer and the second knit layer of the seamless bootie or textile upper (i.e., the first knitted component portion) to form a pocket for receiving an insert member. For example, in some embodiments an insert member may include a toe cup at a forefoot portion of the article, a heel cup at a heel portion of the article, an arch support at an instep portion of the article, a padded layer for a tongue, and/or another insert member.
FIGS. 25 to 35 illustrate embodiments of a seamless bootie or textile upper including tucked in portions. Embodiments illustrated in FIGS. 25 to 35 are similar in that each includes a seamless bootie or textile upper of unitary warp knit construction, including a tucked-in portion that is continuous with the bootie at a closure structure of the bootie. In some embodiments, the tucked-in portions may provide a dynamic fit structure. In some embodiments, the tucked-in portions may provide a gusseted tongue structure.

FIG. 30 illustrates secondary (inner) knitted component 2562 (shown in phantom) fully inverted, folded, or tucked into primary (outer) knitted component 2560. With this arrangement, knitted component 2562 and knitted component 2560 may form a bootie-in-a-bootie configuration of a textile upper of an article of footwear. In some embodiments, a size and configuration of secondary (inner) knitted component 2562 may be substantially the same as a size and configuration of primary (outer) knitted component 2560. It will be appreciated, however, that in some embodiments a size of secondary (inner) knitted component 2562 may be made slightly less than a size of primary (outer) knitted component 2560 (e.g., for tolerance fit). In some embodiments, primary (outer) knitted component 2560 may be stretched more than secondary (inner) knitted component 2562. Those skilled in the art readily will be able to select a sizing and configuration suitable for a desired seamless bootie or textile upper.
