     DETAILED DESCRIPTION 
     The subject matter of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this disclosure. Rather, the inventors have contemplated that the claimed or disclosed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms “step” and/or “block” might be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly stated. 
     At a high level, aspects herein are directed to knit components having one or more apertures formed by an activatable yarn. Generally, the activatable yarn responds to a stimulus (such as thermal energy or an aqueous solution) such that the activatable yarn dissipates, dissolves, melts, and the like thereby forming an aperture in the knit component. The aperture may be positioned between a first knit course and a second knit course that each comprise a stable yarn type. The yarn type is stable as it does not generally respond to the stimulus by dissipating, dissolving, melting, and the like. Generally, the stable yarn type may maintain its structural integrity upon being exposed to the stimulus. That is, if the stable yarn type comprises one or more filaments that are assembled together, this assembly is maintained even after being exposed to the stimulus. Accordingly, the first and second knit courses will remain and form a knit structure surrounding the aperture. By utilizing an activatable yarn type and a stable yarn type to form the aperture, it allows for quick and efficient manufacturing of apertures in knit components. For example, it may remove any post-processing alterations to the knit component (cutting, seaming, and the like) used to form apertures. As a further example, forming an aperture using an activatable yarn type removes the increased manufacturing time that is associated with modifying the knitting rotations on, for example, a circular knit machine used to knit the knit component. 
     Continuing, an aperture may be formed in a knit component based on knitting one or more intermediate knit courses with an activatable yarn type where the one or more intermediate knit courses are positioned between the first yarn course and the second yarn course and may be interlooped with the first yarn course and/or the second yarn course. For example, the activatable yarn type may be a fusible yarn type or a dissolvable yarn type. The activatable yarn may extend throughout the intermediate knit course(s) in a course-wise direction. Additionally, the one or more intermediate knit courses may comprise consecutively knit courses in a wale-wise direction. At any point during the knitting of the one or more intermediate knit courses, the stable yarn types of the first knit course (positioned on a first side the aperture—e.g., below the aperture) and the second knit course (positioned on an opposite side of the aperture—e.g., above the aperture) may be interlooped using, for instance, a tuck stitch or a held stitch. 
     At some point, after the knit component is knit with the activatable yarn type and the stable yarn type, the knit component may be exposed to the stimulus. For example, the knit component may be removed from a knit machine and exposed to steam or water. The activatable yarn will then dissipate, leaving behind the aperture. As described in greater detail below, while the activatable yarn type is described as “dissipating,” it is contemplated that, in some aspects, portions of the activatable yarn type may still be present in the knit component. For instance, the activatable yarn type may have washed away or may have fused to the surrounding stable yarn types. Additionally, portions of the activatable yarn type may not have fully dissipated as the knit component may not have been exposed to enough stimulus or not exposed to the stimulus for an adequate amount of time, which would leave portions of the activatable yarn type still present in the knit component. 
     After the knit component has been exposed to the stimulus, one or more apertures may be formed in the knit component. Specifically, the one or more apertures may be formed in areas once occupied or containing the one or more intermediate knit courses that were knit with the activatable yarn type. As such, the one or more apertures may extend throughout the previously knit intermediate courses in the course-wise direction. Additionally, the one or more apertures may extend in the wale-wise direction, such as in instances where the intermediate knit courses were consecutively knit. 
     As mentioned, the stable yarn type of the first knit course (positioned on the first side of the aperture, e.g., below the aperture) and the second knit course (positioned on the opposite side of the aperture, e.g., above the aperture) may be interlooped using, for instance, a tuck stitch or a held stitch, to form at least in part, for example, a perimeter edge of the aperture. Accordingly, the width of the aperture in the course-wise direction may be defined in part by the interlooping of the stable yarn type of the first knit course and the second knit course. 
     The perimeter edge that defines the aperture may extend through a first, a second, a third, and a fourth area. The first area and the third area of the perimeter edge may be defined by the interlooping (e.g., the tuck or held stitch) of the stable yarn type of the first knit course with the stable yarn type of the second knit course as described above. The second area may be defined in part by one or more knit courses on the first side of the aperture (e.g., below the aperture) being interlooped, while the fourth area may be defined in part by one or more knit courses on the second side (e.g., above the aperture) being interlooped. 
     The present disclosure relies on several terms, so definitions are provided here for the sake of clarity. Throughout this disclosure, an activatable yarn type may be described as “dissipating,” “dissipate,” or “dissipated.” These terms generally refer to a change in a physical state of the activatable yarn type such that the yarn strand disintegrates. To describe this differently, the fibers, filament, and/or filaments of the activatable yarn type may have disintegrated or lost their structural integrity either because they melted or were dissolved. In some aspects, all the fibers, filament, or filaments of the activatable yarn type disintegrate based on being exposed to the stimulus. 
     Examples of an activatable yarn type include a fusible yarn type or a dissolvable yarn type. The term dissipation may be interpreted differently based on whether the activatable yarn type is a fusible yarn type or a dissolvable yarn type. For example, the term “dissipation” with respect to a fusible yarn may refer to fusible yarn melting and/or fusing to the surrounding knit structure. Referring to a dissolvable yarn, the term dissipating may refer to the activatable yarn type dissolving and being washed away. In some aspects, an activatable yarn type has a lower melting point than a stable yarn type. In some aspects, the activatable yarn type may have a melting point from about 40 degrees Celsius to about 160 degrees Celsius. In some aspects, the melting point of the activatable yarn is from about 60 degrees Celsius to about 110 degrees Celsius. Example activatable yarn types include a polyester yarn such as a 33 decitex polyester yarn and/or a 55 decitex polyester yarn, each having a melting point of about 60 degrees Celsius. Further example activatable yarn types include a polyamide yarn such as a 23 decitex polyamide yarn having a melting point of about 110 degrees Celsius. The term “about” used when, for instance, describing numbers or numerical ranges means within ±10% of a designated value unless indicated otherwise. 
     Continuing, the term “dissipation” is not necessarily intended to mean that the activatable yarn type is not present in the knit component. In actuality, portions of the activatable yarn type may remain in the knit component. This may occur, for example, in aspects where the activatable yarn is a fusible yarn and portions of the fusible yarn fuse to the surrounding knit structure. As such, the activatable yarn type may still be present in the knit component even though it has dissipated. Additionally, portions of the activatable yarn type may still be present if the activatable yarn type was exposed to too little of stimulus or was exposed to the stimulus for too little of time. 
     It should be appreciated that while some of the figures depict the activatable yarn type as being absent, this is not intended to communicate that the activatable yarn is entirely absent from the knit component. For example, in some aspects, the activatable yarn may be a fusible yarn such that it fuses to the surrounding knit structure, which is not illustrated herein. As such, in some example aspects, the activatable yarn type is technically present because the fusible yarn may have bonded or fused to surrounding stable yarn types. 
     The term “stimulus” as used herein generally refers to an environmental condition that triggers the activatable yarn type to dissipate. To describe this differently, the physical structure of the fibers, filament, or filaments in the activatable yarn may break down or lose their structural integrity based on being exposed to the stimulus. The stimulus may be any condition, such as an aqueous solution or thermal energy. Example stimuli include water, steam, heat, and the like. 
     The term “stable yarn” type as used herein refers to yarn types that are dimensionally stable when exposed to the stimulus. For example, yarn types are dimensionally stable if they do not dissipate when exposed to the stimulus. In other words, stable yarn types are dimensionally stable because they generally maintain the same filament or fiber count after being exposed to the stimulus. To describe this differently, the stable yarn type maintains its structure despite being exposed to the stimulus. It is contemplated that while the stable yarn type may undergo slight changes, such as shrinking or expanding, the overall structural integrity of the stable yarn type is maintained. As such, the stable yarn type does not respond to the stimulus in the same way that the activatable yarn type responds to the stimulus. Example stable yarn types include a polyester yarn, nylon yarn, cotton yarn, or cotton blend yarn having a higher melting point than an activatable yarn type. In some aspects, the stable yarn type may have a melting point from about 180 degrees Celsius to about 300 degrees Celsius. In some aspects, the stable yarn type may have a melting point from about 220 degrees Celsius to about 300 degrees Celsius. In some aspects, the stable yarn type may have a melting point from about 250 degrees Celsius to about 300 degrees Celsius. 
     The term “first state” as used herein refers to a state of a knit component before it is exposed to a stimulus. The term “second state” as used herein refers the state of the knit component after it has been exposed to a stimulus. 
     The term “course” as used herein refers to a predominantly horizontal row of knit loops (in an upright fabric as knit) that are produced by adjacent needles during the same knitting cycle. The knit course may comprise one or more stitch types such as a loop stitch, a held stitch, a float stitch, a tuck stitch, a transfer stitch, and the like as these terms are known in the art of knitting. The term “wale” as used herein is a predominantly vertical column of intermeshed or interlooped knit loops, generally produced by the same needle at successive (but not necessarily all) courses or knitting cycles. The terms “horizontal” and “vertical” as used herein are relative to an upright fabric as knit in which the heads of knit loops face toward the top of the fabric and the course knit first is oriented toward the bottom of the fabric. 
     The term “held loop” as used herein may include a loop having legs (or a base) that interloop in a first course and a head that interloops in a second course, wherein one or more intermediary courses are arranged between the first course and the second course. Based on this definition, a held loop is generally created by holding a loop in a needle for one or more intermediary courses in a manner that avoids interlooping with the intermediary courses, before eventually interlooping with a stitch in the second course. The term “tuck stitch” as used herein generally refers to a held loop and a tuck loop. The tuck stitch may be created when a needle holding the held loop receives a new yarn segment that passes. The new yarn segment becomes a tuck loop that is included with the needle having the held loop. The term “held stitch” as used herein generally refers to a held loop and a float loop. The float loop may be created when a needle holding a held loop fails to receive a new yarn segment that passes. The term “plating” as used herein means a knit construction where a yarn and one or more plating yarns are knit in the same knit stitch using, for instance, a body yarn feeder and one or more plating yarn feeders. When a particular knit course is described as comprising one or more yarn types, it is contemplated herein that the one or more yarn types are in a plated relationship. 
     The term “integrally knit” as used herein may mean a textile or fabric having a yarn from one or more knit courses being interlooped with one or more knit courses of another area. For instance, a knit course from a first area of a knit component may be integrally knit with a knit course from a second area of the knit component if a yarn from the first area is interlooped with a knit course in the second area. 
     Unless otherwise noted, all measurements provided herein are measured at standard ambient temperature and pressure (25 degrees Celsius or 298.15 K and 1 bar) with the knit component in a resting or non-tensioned state. 
       FIGS. 1 and 2  depict a first state and a second state of a knit component  100  depicted in schematic form.  FIG. 1  includes a magnified photographic view  136  of a portion of a first area  102  when the knit component  100  is in the first state.  FIG. 2  includes a magnified photographic view  138  of the first area  102  when the knit component  100  is in the second state. Additionally, the knit component  100  further comprises a second area  104 . In some aspects, the second area  104  is located between two or more first areas (e.g.,  102 ). 
     The knit component  100  may be any type of knit structure that is knit by a circular or flat-knit machine. For example, the knit component  100  may be any garment, article of footwear, article of headwear, gloves, bag, or the like, that has a knit structure. In some aspects, as described in reference to  FIGS. 11-13 , the knit component  100  can be a knit sock, a knit shirt, or a knit upper. In some aspects, the knit component  100  is integrally knit and forms an entirety of an article. It is also contemplated herein that the knit component  100  may be joined to one or more additional components (knit, woven, nonwoven) to form an article. 
     Referring initially to  FIG. 1 , the first area  102  may comprise a plurality of knit courses. The first area  102  may comprise one or more first knit courses  106 , one or more intermediate knit courses  122 , and one or more second knit courses  108 . The one or more intermediate knit courses  122  may be positioned between the one or more first knit courses  106  and the one or more second knit courses  108 . 
     Each of the plurality knit of courses in the first area  102  may comprise different yarn types, such as a stable yarn type and an activatable yarn type. In some aspects, the one or more first knit courses  106  and the one or more second knit courses  108  are knit with the stable yarn type, such as stable yarn  118 . The one or more intermediate knit courses may be knit with an activatable yarn type, such as activatable yarn  120 . It is contemplated that the one or more first knit courses  106  and the one or more second knit courses  108  may further comprise an activatable yarn type that is plated with the stable yarn type. Additionally, it is contemplated that the one or more first knit courses  106  and the one or more second knit courses  108  may further comprise two stable yarn types, where a first stable yarn type is plated with a second stable yarn type. Thus, in example aspects, the one or more first knit courses  106  and the one or more second knit courses  108  may comprise a first stable yarn type plated with a second stable yarn type and further plated with an activatable yarn type. Any and all aspects, and any variation thereof, are contemplated as being within the scope herein. 
     Continuing, the one or more first knit courses  106  and the one or more second knit courses  108  may be interlooped with the one or more intermediate knit courses  122 . As shown, the stable yarn  118  of the one or more first knit courses  106  may be interlooped with the activatable yarn  120  of the one or more intermediate knit courses  122 , as depicted by reference numeral  124 . The activatable yarn  120  of the one or more intermediate knit courses  122  may further be interlooped with the stable yarn  118  of the one or more second knit courses  108 , as depicted by reference numeral  126 . 
     In some aspects, the stable yarn  118  of the one or more first knit courses  106  may be interlooped with the stable yarn  118  of the one or more second knit courses  108  at one or more intervals, such as at one or more intervals  116   a - e  using, for instance, a tuck stitch or a held stitch. In some aspects, the one or more intervals  116   a - e  may be described as being present at predefined intervals. For instance, a knit machine may be programmed to interloop the one or more first knit courses  106  with the one or more second knit courses  108  at predefined intervals. 
     Based on being exposed to a stimulus, the activatable yarn  120  in the one or more intermediate knit courses  122  may dissipate. As such, the one or more intermediate knit courses  122  in the first area  102  may dissipate as well. For example, as shown in  FIG. 1 , the one or more intermediate knit courses  122  are present along with the one or more first knit courses  106  and the one or more second knit courses  108 . Yet, as shown in  FIG. 2 , the one or more intermediate knit courses  122  are depicted as being absent to form an aperture such as aperture  110   b.    
     Because the one or more intermediate knit courses  122  in the first area  102  dissipate, one or more apertures, such as one or more apertures  110   a - e , are formed in the knit component  100 . In particular, as shown in  FIG. 2 , the one or more apertures  110   a - e  are formed between the one or more first knit courses  106  and the one or more second knit courses  108 . Additionally, the one or more apertures  110   a - e  may be formed between the one or more intervals  116   a - e , where the one or more first knit courses  106  are interlooped with the one or more second knit courses  108  using a tuck stitch or a held stitch. In this way, the one or more apertures  110   a - e  are formed in the first area  102  of the knit component  100 . 
     The first area  102  may include any number of apertures. In some aspects, the one or more apertures  110   a - e  may appear as a mesh or lattice-like structure. Additionally, the one or more apertures  110   a - e  may be physically oriented (height, width, shape, spacing between apertures, patterns, and the like) in any configuration. For example, in  FIG. 2 , the first area  102  depicts the one or more apertures  110   a - e  in a diamond-like pattern. Additionally, it is contemplated that in tubular knit components (e.g., a sock) the first area  102  may extend circumferentially around the tubular portion of the sock. 
     As mentioned, the knit component  100  further comprises the second area  104 . In some aspects, each knit course in the second area  104  comprises a stable yarn type, such as stable yarn  118 . And in some aspects, it is contemplated that the second area  104  may not comprise any activatable yarns. Accordingly, in example aspects, the second area  104  may not include apertures formed by the activatable yarn type. It is contemplated that the knit component  100  may include any number of first areas (e.g.,  102 ) or any number of second areas (e.g.,  104 ). 
       FIG. 3  illustrates a schematic depiction  300  of a first area  302  of an example knit component, such as the knit component  100 . Some features of the schematic depiction  300  may be similar to that shown on a knit programming file (e.g., a bitmap) that is used in knitting the knit component, such as the knit component  100 . The bitmap may be used to instruct a knit machine, such as a circular knit machine or a flat knit machine, to knit the example knit component. 
       FIG. 3  depicts a plurality of knit courses schematically. For example, each horizontal line depicts a knit course. For illustrative purposes, a space is shown between each course, but in reality, the courses would be interlooped. The schematic depiction  300  illustrates one or more first knit courses  306  spaced apart from one or more second knit courses  308  by one or more intermediate knit courses  322 . In actuality, in some aspects, portions of the one or more first knit courses  306  and the one or more second knit courses  308  may be brought together in physical proximity based on the interlooping of their respective yarns at intervals  316   a - e  using tuck stitches or held stitches as indicated by reference numerals  325 ,  326 ,  328 ,  329 , and  330  (shown schematically as vertical lines). For example, as shown in  FIG. 1 , the one or more first knit courses  106  are brought together in physical proximity with the one or more second knit courses  108  at the one or more intervals  116   a - e.    
     While discussed in greater detail below, the schematic depiction  300  includes a first magnified view  342  of an example transition prior to the one or more first knit courses  306 , the one or more second knit courses  308 , and the one or more intermediate knit courses  322 . Similarly, the schematic depiction  300  includes a second magnified view  343  of an example transition after the one or more first knit courses  306 , the one or more second knit courses  308 , and the one or more intermediate knit courses  322 . 
     As discussed below, the example transitions illustrate the dropping in or introduction of various yarn types. It should be appreciated that the dropping in or introduction of the various yarn types may be at any point during the knitting of a particular course. The example transitions also illustrate the dropping out or removal of the various yarn types. It should be appreciated that the dropping out or removal of the various yarn types may be at any point during the knitting of the particular course. It is contemplated that the various yarn types may be cut and secured (e.g., tied) once dropped out. It is further contemplated that the dropping out of the various yarn types may including floating the various yarn types until they are re-introduced. 
     The schematic depiction  300  and the first and second magnified views  342  and  343  illustrate the one or more first knit courses  306 . In some aspects, the one or more first knit courses  306  may comprise a first knit course  340 . The first knit course  340  is depicted as a solid horizontal line to indicate that it may comprise three yarn types, such as a first yarn type, a second yarn type, and a third yarn type. In some aspects, the first yarn type and the second yarn type may be one or more stable yarn types, such that the first yarn type may comprise a body yarn and the second yarn type may comprise a plating yarn. In some aspects, the third yarn type may be an activatable yarn type that is plated with the first yarn type and the second yarn type. As illustrated in the first magnified view  342 , reference numeral  344  indicates an example transition of dropping in or introducing the third yarn type. 
     In an example aspect, the one or more first knit courses  306  may comprise a second knit course  350 . A segment of the second knit course  350  is depicted as a semi-dashed (long-short) horizontal line to indicate that it may comprise two yarn types, such as the second yarn type and the third yarn type in a plated relationship. The segment of the second knit course  350  depicted as the semi-dashed horizontal line may not comprise the first yarn type. It should be appreciated that, in some aspects, the third yarn type may be introduced or dropped in. As shown in the first magnified view  342 , reference numeral  352  depicts an example transition of where the third yarn type may be dropped in or introduced into the second knit course  350 . 
     In some aspects, the first yarn type may be dropped out or removed from the second knit course  350 . Reference numeral  353  illustrates an example transition of where the first yarn type is dropped out or removed. Thus, the segment of the second knit course  350  indicated by the reference numeral  353  may comprise just the first yarn type and the second yarn type without the third yarn type before the third yarn type is introduced at reference numeral  352  and the first yarn type is dropped out. 
     As mentioned, the schematic depiction  300  illustrates the one or more intermediate knit courses  322 . The courses of the one or more intermediate knit courses  322  are depicted with a dashed (even length) horizontal line to illustrate that they may comprise just the third yarn type. In some aspects, the third yarn type may be dropped in or introduced prior to knitting the one or more intermediate knit courses  322 . As shown in the first magnified view  342 , reference numeral  362  depicts an example transition where the third yarn type may be dropped in or introduced prior to the one or more intermediate knit courses  322 . 
     Continuing, reference numeral  364  indicates an example transition of dropping out both the first yarn type and the second yarn type. While  FIG. 3  depicts the example transition (e.g.,  364 ) as a single point, it is contemplated that the first yarn type and the second yarn type may be dropped out or removed sequentially or simultaneously. For example, in one aspect, the example transition may include dropping out or removing the first yarn type before the second yarn type. In another aspect, the example transition may include dropping out or removing the second yarn type before the first yarn type. Based on the dropping out or removing the first yarn type and the second yarn type, the one or more intermediate knit courses  322  may comprise the third yarn type and not the first yarn type nor the second yarn type. To describe this differently, the one or more intermediate knit courses  322  may be knit with the third yarn type and not the first yarn type nor the second yarn type. 
     As mentioned, the schematic depiction  300  illustrates the one or more second knit courses  308 . In some aspects, the one or more second knit courses  308  may comprise a third knit course  370 . A segment of the third knit course  370  is depicted as a semi-dashed (long-short) horizontal line to indicate that it may comprise two yarn types, such as the second yarn type and the third yarn type. The segment of the third knit course  370  depicted as the semi-dashed horizontal line may not comprise the first yarn type. It should be appreciated that, in some aspects, the third yarn type may be introduced or dropped in. As shown in the first magnified view  342 , reference numeral  374  depicts an example transition of where the third yarn type may be dropped in or introduced into the third knit course  370 . 
     In some aspects, the first yarn type may be dropped out or removed from the third knit course  370 . Reference numeral  372  illustrates an example transition of where the first yarn type is dropped out or removed. Thus, the segment of the third knit course  370  indicated by the reference numeral  372  may comprise just the first yarn type and the second yarn type without the third yarn type before the third yarn type is introduced at reference numeral  374  and the first yarn type is dropped out. 
     In some aspects, the one or more second knit courses  308  may comprise a fourth knit course  380 . The fourth knit course  380  is depicted as a solid horizontal line to indicate that it may comprise three yarn types, such as the first yarn type, the second yarn type, and the third yarn type. In some aspects, the third yarn type may be dropped in or introduced into the fourth knit course  380 . As illustrated in the first magnified view  342 , reference numeral  382  indicates an example transition of dropping in or introducing the third yarn type. 
     With continued reference to  FIG. 3 , the schematic depiction  300  shows the one or more intermediate knit courses  322  as being interrupted by the tuck stitches or held stitches  325 ,  326 ,  328 ,  329  and  330  at the one or more intervals  316   a - e . The tuck stitches or held stitches  325 ,  326 ,  328 ,  329  and  330  comprise an interlooping of the one or more first knit courses  306  with the one or more second knit courses  308 . It should be appreciated that the tuck stitches or held stitches  325 ,  326 ,  328 ,  329  and  330  may define in part a perimeter edge of an aperture that is formed after the one or more intermediate knit courses  322  dissipate. 
     The interlooping of yarns at the one or more intervals  316   a - e  may form one or more knit segments  390   a - d  in each of the one or more intermediate knit courses  322 . The length of the one or more knit segments  390   a - d  may include any number of wales in the course-wise direction. By way of example, each of the one or more knit segments  390   a - d  may comprise between 1 wale and 50 wales. It should be appreciated that the length of the one or more knit segments  390   a - d  may correspond to the length of the one or more apertures (e.g., the one or more apertures  110   a - e ) to be formed in the knit component after it has been exposed to a stimulus. It should be appreciated that while  FIG. 3  illustrates four knit segments (e.g.,  390   a - d ) located between the one or more intervals  316   a - e , any number of knit segments may be formed in the one or more intermediate knit courses  322 . 
     As mentioned, the second magnified view  343  illustrates an example transition after the one or more first knit courses  306 , the one or more second knit courses  308 , and the one or more intermediate knit courses  322 . Reference numeral  346  indicates an example transition of dropping out or removing the third yarn type from the first knit course  340 . With respect to the second knit course  350 , reference numeral  354  indicates an example transition of dropping in or re-introducing the first yarn type while reference numeral  356  indicates an example transition of dropping out or removing the third yarn type. 
     With respect to the one or more intermediate knit courses  322 , reference numeral  365  indicates an example transition of dropping in or re-introducing the first and second yarn types, while reference numeral  366  indicates the dropping out or removal of the third yarn type. It is contemplated that dropping in or re-introduction of the first and second yarn types may be sequentially or simultaneously. 
     With respect to the one or more second knit courses  308 , reference numeral  376  indicates an example transition of dropping in or re-introducing the first yarn type in the third knit course  370 . Reference numeral  378  indicates an example transition of dropping out or removing the third yarn type from the third knit course  370 . With respect to the fourth knit course  380 , reference numeral  384  indicates an example transition of dropping out or removing the third yarn type. 
     As mentioned, in some aspects, the one or more first knit courses  306  and the one or more second knit courses  308  are described as comprising the third yarn type. It should be appreciated that, in some aspects, the activatable yarn type may fuse to the surrounding knit structure after it has been activated. This may be advantageous as it may strengthen a perimeter edge of an aperture that will be formed in a knit component (e.g., the knit component  100 ) after it has been exposed to the stimulus. It is contemplated that in some aspects, the one or more first knit courses  306  and the one or more second knit courses  308  may not comprise the third yarn type. 
       FIGS. 4-5  illustrate an example of a knit structure  400  in a first area of the knit component  100 , such as the first area  102  of  FIG. 1 .  FIGS. 4-5  are provided to illustrate the first and second state of the knit structure  400 , respectively. The knit structure  400  illustrates a plurality of knit courses  412  comprising consecutively arranged knit courses and consecutively arranged wales, with knit stitches forming, for instance, a single-jersey knit. 
     The plurality of knit courses may comprise one or more first knit courses  406 , one or more second knit courses  408 , and one or more intermediate knit courses  422  that are positioned between the one or more first knit courses  406  and the one or more second knit courses  408 . These knit courses may be similar the one or more first knit courses  306 , the one or more second knit courses  308 , and one or more intermediate knit courses  322  of  FIG. 3 . For example, in some aspects, the one or more first knit courses  406  may comprise a first knit course  420  and a second knit course  421 . In some aspects, the one or more second knit courses  408  may comprise a third knit course  424 , a fourth knit course  426 , and a fifth knit course  427 . 
     It should be appreciated that the yarn segments of the courses are depicted in a particular manner to more easily distinguish the type of yarns in each of the plurality of knit courses. For instance, the first knit course  420 , the fourth knit course  426 , and the fifth knit course  427  are depicted with a positive slope hatching to illustrate that they may comprise a first yarn type, a second yarn type, and a third yarn type (similar to the yarn types described in  FIG. 3 ). The second knit course  421  and the third knit course  424  are depicted in a stipple to illustrate that they may comprise the second yarn type, and the third yarn type. Additionally, the one or more intermediate knit courses  422  are depicted in a cross-hatching to indicate that they may comprise the third yarn type. 
     The one or more intermediate knit courses  422  are depicted with break lines to convey that the one or more intermediate knit courses  422  may include additional intermediate knit courses arranged between the one or more first knit courses  406  and the one or more second knit courses  408 . Any number of intermediate knit courses may be included in the one or more intermediate knit courses  422 . For example, the one or more intermediate knit courses  422  may include as many courses as a needle will tolerate before the tension of a tuck stitch is too high. By way of example, the one or more intermediate knit courses  422  may comprise from about one knit course to about thirty knit courses, from about one knit course to about 10 knit courses, from about one knit course to about 7 knit courses, or from about one knit course to about 5 knit courses. It should be appreciated that varying the number of knit courses within the one or more intermediate knit courses  422  may be advantageous as it varies a height of an aperture that will be formed in the knit component  100 . To describe this differently, varying the number of consecutively knit intermediate courses determines how far the aperture extends in the wale-wise direction after a stimulus has been introduced. 
     As shown, in some aspects, the first knit course  420  is interlooped with the second knit course  421 . For example, the yarn(s) of the first knit course  420  may be interlooped with the yarn(s) of the second knit course  421 . In some aspects, the third knit course  424  is interlooped with the fourth knit course  426 . For example, the yarn(s) of the third knit course  424  may be interlooped with the yarn(s) of the fourth knit course  426 . And the fourth knit course  426  is interlooped with the fifth knit course  427 . 
     In some aspects, the one or more first knit courses  406  and the one or more second knit courses  408  may be interlooped with the one or more intermediate knit courses  422 . For example, with respect to  FIG. 4 , the second knit course  421  may be interlooped with the one or more intermediate knit courses  422 . Additionally, the third knit course  424  may be interlooped with the one or more intermediate knit courses  422 . 
     In some aspects, the one or more first knit courses  406 , the one or more second knit courses  408  and the one or more intermediate knit courses  422  may be interlooped using a tuck stitch (e.g.,  428 ,  430 , and  432 ) at one or more intervals  416   a - c . Each tuck stitch  428 ,  430 , and  432  may comprise a held loop  442  and one or more tuck loops  444 . Both the held loop  442  and the one or more tuck loops  444  may be interlooped with the yarn(s) in the one or more second knit courses  408 . 
     The one or more tuck loops  444  may comprise any of the yarn type(s) from the one or more first knit courses  406 , the one or more second knit courses  408 , and the one or more intermediate knit courses  422 . For example, as shown in  FIG. 4 , the one or more tuck loops  444  may comprise the yarn types of the second knit course  421 , the one or more intermediate knit courses  422 , the third knit course  424 , and the fourth knit course  426 . The tuck stitches  428 ,  430 , and  432  may be advantageous as it may reinforce a perimeter edge of an aperture that will be formed in the knit component  100  after it has been exposed to a stimulus. 
     As mentioned, each of the tuck stitches  428 ,  430 , and  432  may comprise the held loop  442 . The held loop  442  may include held loop legs  436 ,  438  that extend from a held loop base  440  through the plurality of knit courses  412 . In some aspects, the held loop base  440  may be located in the one or more first knit courses  406 . The held loop legs  436 ,  438  may then extend across the one or more intermediate knit courses  422 . The held loop legs  436 ,  438  may be interlooped with a course in the one or more second knit courses  408 . In an example aspect, as shown in  FIG. 4 , the held loop base  440  may be located in the first knit course  420 . The held loop legs  436 ,  438  may then extend through the first knit course  420 , the second knit course  421 , the one or more intermediate knit courses  422 , the third knit course  424 , and the fourth knit courses  426 . A head of the held loop  442  may then be positioned in the fifth knit course  427 . 
     It is contemplated that, in some aspects, the head of the held loop  442  may be positioned in the fourth knit course  426  or the third knit course  424 . For example, if the head of the held loop is positioned in the fourth knit course  426 , the held loop legs  436 ,  438  may extend through the first knit course  420 , the second knit course  421 , the one or more intermediate knit courses  422 , and the third knit course  424 . As a further example, if the head of the held loop is positioned in the third knit course  424 , the held loop legs  436 ,  438  may extend through the first knit course  420 , the second knit course  421 , the one or more intermediate knit courses  422 , and the third knit course  424 . 
     It should be appreciated that, in some aspects, the one or more intermediate knit courses  422  may have dissipated after exposure to a stimulus, as illustrated in  FIG. 5 . Accordingly, when the knit structure  400  is in the second state, the tuck stitches  428 ,  430 , and  432  may appear to extend across four knit courses (e.g., the first knit course  420 , the second knit course  421 , the third knit course  424 , and the fourth knit course  426 ). Accordingly, in some aspects, at least when the knit component  100  is initially knit, the tuck stitches  428 ,  430 , and  432  are held for at least five knit courses as it includes the one or more intermediate knit courses  422 . 
     In some aspects, the one or more intervals  416   a - c  may comprise any number of wales. As shown,  FIG. 4  depicts the example tuck stitch  430  in a single wale  418 . Accordingly, in some aspects, the one or more intervals  416   a - c  may each comprise a tuck stitch in a single wale. However, it is contemplated that the one or more intervals  416   a - c  may extend across any number of consecutive wales, where each consecutive wale includes a tuck stitch. For example, the number of wales may range from two consecutive wales to thirty consecutive wales. It should be appreciated that knitting consecutive tuck stitches in a plurality of wales may determine the spacing between one or more apertures (e.g.,  410   a - b ) that will be formed in the example knit component  100 . 
     In some aspects, the one or more tuck stitches  428 ,  430 , and  432  may form one or more knit segments  450   a - b . The one or more knit segments  450   a - b  may comprise one or more intermediary wales (e.g.,  411 ,  413 ,  414 , and  416 ). More particularly, the knit segment  450   a  comprises the intermediary wales  411  and  413 , and the knit segment  450   b  comprises the intermediary wales  414  and  416 . It is contemplated that each of the one or more knit segments  450   a - b  may extend across any number of wales. For example, the number of intermediary wales may range from one to forty wales. It should be appreciated that the number of intermediary wales will determine the length of the aperture (e.g., one or more apertures  410   a - b ) in the course-wise direction. 
     With respect to  FIG. 5 , the knit structure  400  has been exposed to the stimulus and the one or more apertures  410   a - b  are formed after the one or more intermediate knit courses  422  dissipate. As such, the one or more apertures  410   a - b  may be formed in the plurality of knit courses  412 . In some aspects, the one or more apertures  410   a - b  may be located between the one or more first knit courses  406  and the one or more second knit courses  408 . As shown, in an example aspect, the one or more apertures  410   a - b  may be positioned between the second knit course  421  and the third knit course  424 . 
     In addition, in some aspects, the one or more apertures  410   a - b  may be located between the interlooping of the first knit course  420  and the fourth knit course  426  at intervals  416   a - c . In some aspects, the one or more apertures  410   a - b  may be located between the one or more tuck stitches  428 ,  430 , and  432 . In some aspects, a perimeter edge of the one or more apertures  410   a - b  may be defined in part by the one or more tuck stitches  428 ,  430 , and  432 . 
     In some aspects, each of the one or more apertures  410   a - b  may have a width of the one or more knit segments  450   a - b . To describe this differently, the one or more apertures  410   a - b  may extend across the one or more intermediary wales (e.g.,  411 ,  413 ,  414 , and  416 ). For example, aperture  410   a  may extend across intermediary wales  411 ,  413 , while aperture  410   b  may extend across intermediary wales  414 ,  416 . The width of each of the one or more apertures  410   a - b  may be determined by the number of wales in each of the knit segments  450   a - b.    
     Turning now to  FIGS. 6-7 , these figures illustrate an alternative example of a knit structure  600  in a first area of the knit component  100 , such as the first area  102  of  FIG. 1 . In particular,  FIG. 6  is provided to illustrate the first state of the knit structure  600 , while  FIG. 7  is provided to illustrate the second state of the knit structure  600 . 
     The knit structure  600  is generally the same as the knit structure  400  as described in  FIGS. 4-5 . For example, the knit structure  600  comprises a plurality of knit courses  612  that are similar to the plurality of knit courses  412 . As such, the knit structure  600  may comprise one or more first knit courses  606 , one or more intermediate knit courses  622 , and one or more second knit courses  608 . In some aspects, the one or more first knit courses  606  may comprise a first knit course  620  and a second knit course  621 . The one or more second knit courses  608  may comprise a third knit course  624 , a fourth knit course  626 , and a fifth knit course  627 . 
     In some aspects, the knit structure  600  may comprise one or more held stitches  628 ,  630 , and  632  at one or more intervals  616   a - c . For example, in some aspects, the one or more first knit courses  606  may be interlooped with the one or more second knit courses  608  using the held stitches  628 ,  630 , and  632  at the intervals  616   a - c . Each held stitch  628 ,  630 , and  632  may comprise a held loop  642  and one or more float loops  660 . The held loop  642  of the held stitch  630  may be similar to the held loop  442  of the tuck stitch  430  described in  FIG. 4 . 
     As mentioned, the held stitches  628 ,  630 , and  632  may comprise the one or more float loops  660 . In example aspects, the second knit course  621 , the one or more intermediate knit courses  622 , the third knit course  624 , and the fourth knit course  626  may comprise a float loop  660  at the one or more intervals  616   a - c.    
     In some aspects, the one or more intervals  616   a - c  may extend across any number of wales. As shown,  FIG. 6  depicts the held stitch  630  in a single intermediary wale  618 . Accordingly, in some aspects, the one or more intervals  616   a - c  may comprise a held stitch in a single wale. However, it is contemplated that the one or more intervals  616   a - c  may extend across any number of consecutive wales. For example, the number of wales may range from two consecutive wales to thirty consecutive wales. It should be appreciated that consecutively knitting held stitches in a plurality of wales may determine the spacing between one or more apertures (e.g.,  610   a - b ). 
     In some aspects, the held stitches  628 ,  630 , and  632  may define the boundaries of one or more knit segments  650   a - b  that extend across one or more intermediary wales (e.g.,  611 ,  613 ,  614 , and  616 ). It is contemplated that each of the one or more knit segments  650   a - b  may extend across any number of consecutive wales. For example, the number of intermediary wales may range from one to forty consecutive wales. It should be appreciated that varying the number of intermediary wales will determine the length of the aperture (e.g.,  610   a - b ) in the course-wise direction. 
     It should be appreciated that while  FIGS. 4-5  depict tuck stitches at the one or more intervals  416   a - c , and while  FIGS. 6-7  depict held stitches at the one or more intervals  616   a - c , any and all variations of held stitches and tuck stitches at one or more intervals are contemplated as being within the scope of this disclosure. 
     Turning now to  FIG. 7 , the knit structure  600  has been exposed to the stimulus and the one or more apertures  610   a - b  are formed after the one or more intermediate knit courses  622  dissipate. As such, the one or more apertures  610   a - b  may be formed in the plurality of knit courses  612 . In some aspects, the one or more apertures  610   a - b  may be located between the one or more first knit courses  606  and the one or more second knit courses  608 . As shown, in an example aspect, the one or more apertures  610   a - b  may be located between the second knit course  621  and the third knit course  624 . In addition, in some aspects, the one or more apertures  610   a - b  may be located between the one or more held stitches  628 ,  630 , and  632 . In some aspects, a perimeter edge of the one or more apertures  610   a - b  may be defined in part by the one or more held stitches  628 ,  630 , and  632 . 
     In some aspects, each of the one or more apertures  610   a - b  may have a width of the one or more knit segments  650   a - b . To describe this differently, the one or more apertures  610   a - b  may extend across the one or more intermediary wales (e.g.,  611 ,  613 ,  614 , and  616 ). For example, the aperture  610   a  may extend across intermediary wales  611 ,  613 , while the aperture  610   b  may extend across intermediary wales  614 ,  616 . 
     Turning now to  FIG. 8 , a portion of a first area  802  of a knit component is illustrated in accordance with aspects described herein. The first area  802  of  FIG. 8  references the knit structure  400  of  FIGS. 5 and 6 , although the first area may have a similar configuration to that shown in  FIG. 7 . The first area  802  of  FIG. 8  is depicted in a second state after the knit component has been exposed to a stimulus. 
     In some aspects, the tension of the tuck stitches  428 ,  430  pulls the one or more first knit courses  406  toward the one or more second knit courses  408 . This results in the first and second knit courses  406 ,  408  being brought closer in proximity. As shown in  FIG. 8 , the tuck stitches  428 ,  430  may cause the first knit course  420  and second knit course  421  to be brought closer in proximity to the third knit course  424  and the fourth knit course  426 , such that the knit courses  420 ,  421 ,  424 , and  426  are adjacent to each other, and the aperture  410   a  in  FIG. 8  assumes a diamond shape. It is contemplated that when the tension of the one or more tuck stitches  428 ,  430  is not high, the one or more first knit courses  406  may not be pulled as close toward the one or more second knit courses  408 . As such, the shape of the aperture  410   a  may appear to have a more rectangular appearance. Any and all aspects, and any variation thereof, are contemplated as being within aspects herein. 
     The aperture  410   a  comprises a perimeter edge  850 . The perimeter edge  850  may comprise one or more areas. In an example aspect, the perimeter edge  850  comprises a first area  810 , a second area  820 , a third area  830 , and a fourth area  840 . The aperture  410   a  may be defined by the perimeter edge  850  that extends from the first area  810  to the second area  820 , from the second area  820  to the third area  830 , from the third area  830  to the fourth area  840 , and from the fourth area  840  back to the first area  810 . 
     In some aspects, the interlooping of various knit courses in the plurality of knit courses  412  may form the one or more areas of the perimeter edge  850 . For example, the first area  810  may be formed by the interlooping of the first knit course  420  and the fourth knit course  426  using the tuck stitch  428  at interval  416   a . The second area  820  may be formed by the interlooping of the third knit course  424  and the fourth knit course  426 . The third area  830  may be formed by the interlooping of the first knit course  420  and the fourth knit course  426  using the tuck stitch  430  at interval  416   b . The fourth area  840  may formed by an interlooping of the first knit course  420  and the second knit course  421 . In example aspects, the second knit course  421  may not be interlooped with the third knit course  424  at the second area  820  or the fourth area  840 . 
     Turning now to  FIG. 9 , a portion of a first area  902  is depicted where apertures  910   a - c  have different heights in the wale-wise direction, in accordance with aspects described herein. As shown, the aperture  910   b  may have a larger height in the wale-wise direction than the aperture  910   a  or the aperture  910   c . To describe this differently, the aperture  910   b  may extend through a greater number of knit courses than the aperture  910   a  or the aperture  910   c.    
     To achieve various heights, the number of the one or more intermediate knit courses can be modified. For instance, a greater number of intermediate knit courses (e.g., the one or more intermediate knit courses  422 ) may increase the height of the one or more apertures  910   a - c . While not shown, a first number of intermediate knit courses comprising the activatable yarn type may be knit in regions  920   a  and  920   c  corresponding to the aperture  910   a  and the aperture  910   c  respectively. A second number of intermediate knit courses comprising the activatable yarn type is knit in a region  920   b  corresponding to the aperture  910   b . The aperture  910   b  has a larger height because the second number of intermediate knit courses in the region  920   b  is greater than the first number of intermediate knit courses in the region  920   a  and in the region  920   c . This is because when the activatable yarn type is exposed to the stimulus, the activatable yarn in the one or more intermediate knit courses will dissipate, thereby forming the aperture  910   b  with a greater height than the apertures  910   a  and  910   c.    
     Turning now to  FIG. 10 , a portion of a first area  1002  having one or more apertures  1010   a - c  of varied widths is depicted in accordance with aspects described herein. The first area  1002  may be similar to the first area  102  of knit component  100 . As shown, the aperture  1010   b  may have a larger width in the course-wise direction than the aperture  1010   a  or the aperture  1010   c . To describe this differently, the aperture  1010   b  may extend along a greater number of wales than the aperture  1010   a  or the aperture  1010   c.    
     To achieve various widths in each of the one or more apertures  1010   a - c , the spacing in regions  1020   a - c  may be increased by knitting the interval  1016   a  further apart from the interval  1016   b . This may determine the course-wise length of the knit segments for any of the intermediate knit courses. Described differently, increasing the number intermediary wales in the knit segments between each of one or more intervals  1016   a - b  may increase the course-wise length of each of the one or more apertures  1010   a - c.    
     For example, a first knit segment in the one or more intermediate knit courses may extend through a first number of intermediary wales in regions  1020   a ,  1020   c . A second knit segment in the one or more intermediate knit courses may extend through a second number of intermediary wales in region  1020   b . To achieve a larger width in the aperture  1010   b  compared to the aperture  1010   a  or the aperture  1010   c , the second number of intermediary wales will generally be greater than the first number of intermediary wales. As such, based on introducing the stimulus, the activatable yarn in the first number of intermediary wales and second number of intermediary wales will dissipate, thereby forming the aperture  1010   b  with a greater width than the aperture  1010   a  or the aperture  1010   c.    
     Additionally, as shown, the one or more apertures  1010   a - c  are spaced apart in the course-wise direction. To space the one or more apertures  1010   a - c  further apart, the number of consecutive wales in each of the intervals  1016   a - b  may be increased. To state it differently, the number of consecutive tuck stitches (or held stitches) in the intervals  1016   a - b  may be increased as shown by the presence of four vertical lines in each of the intervals  1016   a - b . It should be appreciated that varying the length of intervals  1016   a - b  may create a unique aesthetic and different patterns in the first area  1002 . In addition, it may increase or decrease the amount of ventilation. It should be appreciated that, while not shown, the length of each interval within the intervals  1016   a - b  may be varied. In other words, an interval may extend across a greater number of consecutive wales than a different interval. 
     In addition, it is contemplated that a first area within a knit component may have different configurations than another first area. For example, a knit component may have a first area having larger apertures and a different first area with smaller apertures. This may be advantageous as particular regions of the knit component may require greater ventilation than other regions. In addition, in some aspects, a density (e.g., the number of apertures or the spacing between the apertures) of the apertures between the first areas may increase or decrease. Controlling the density of the apertures for each of the first areas (e.g.,  102 ) may increase or decrease the ventilation.
