No. 61/169,615, filed Apr. 15, 2009. This application is also related to U.S. patent application Ser. No. 12/759,364, filed on Apr. 13, 2010 of which all of the disclosures are hereby incorporated by reference.


TECHNICAL FIELD
The invention relates in general to towels, and in particular to quick drying towels.
BACKGROUND INFORMATION
Towels are typically used for drying. Accordingly, commercially available towels are designed for maximum absorption. At maximum absorption, it has been observed that commercially available towels weigh more than desirable, and also require longer than desirable drying times. One approach to reducing towel drying times and weight is to reduce the aesthetic properties (e.g., look and feel) of the towels, such as towels' bulk and softness. However, consumers desire aesthetically pleasing towels with quick drying times. Although commercially available towels have been generally adequate for the intended purposes, they have not been entirely satisfactory in all respects.
What is needed, therefore, is an aesthetically pleasing towels with quick drying times.
SUMMARY
In response to these and other problems, in one embodiment, there is a quick dry towel, comprising a woven ground fabric comprising a plurality of warp yarns substantially parallel to each other, a plurality of weft yarns substantially parallel to each other and intersecting the plurality of warp yarns such that the plurality of weft yarns are substantially perpendicular to the plurality of warp yarns; a plurality of pile weave portions extending from the woven ground fabric; a plurality of flat weave portions alternating between the pile weave portions to form a diagonal design extending across a substantial portion of the towel, wherein the pile weave portions comprise terry loop yarns raised above the woven ground fabric to form terry loops where the loop is substantially wider the terry loop yarn, and the terry loop yarns comprise zero twist yarns such that a fabric weight of the towel is less than 350 g/m2.
These and other features, and advantages, will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings. It is important to note the drawings are not intended to represent the only aspect of the invention.
The present disclosure is best understood from the following detailed description when read with the accompanying figures.

DETAILED DESCRIPTION
For the purposes of promoting an understanding of the principles of the present inventions, reference will now be made to the embodiments, or examples, illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications in the described embodiments, and any further applications of the principles of the inventions as described herein are contemplated as would normally occur to one skilled in the art to which the invention relates.
The present disclosure relates generally to towels, and more particularly, to a quick-dry textured towel. FIG. 1A is a diagrammatic view of a quick-dry textured towel 100 according to an embodiment of the present disclosure, FIG. 1B is a diagrammatic view of a surface portion 100A of the quick-dry textured towel 100 of FIG. 1A, and FIG. 2 is a diagrammatic cross-sectional view of a portion of the quick-dry textured towel 100 of FIG. 1A. The quick-dry textured towel 100 includes a lightweight fabric with a textured weave design. The textured weave design is achieved by alternating pile-weave portions 102 and flat-weave portions 104. The alternating pile-weave portions 102 and flat-weave portions 104 can extend along the length and/or width of the towel. The alternating textured weave design may extend substantially over one or both surfaces of the towel 100. The textured weave design can also be in designated areas of the towel 100 to achieve ornamental design. For example, the alternating textured weave design can extend diagonally with respect to the length and/or width of the towel. The textured weave design gives the quick-dry towel 100 a bulky, soft appearance despite its lightweight.
In the depicted embodiment, the pile-weave portions 102 are sandwiched between flat-weave portions 104. The alternating pile-weave portions 102 and flat weave portions 104 extend from a woven ground fabric 106 of the quick-dry textured towel 100. A “woven fabric” can include fabric made by interlacing two or more systems of yarns at essentially right angles to each other. For example, the woven ground fabric 106 can include a set of warp yarns and a set of weft (or filling) yarns intersecting and locked together. The set of warp yarns are substantially parallel to each other and the set of weft yarns are substantially parallel to each other. The set of warp yarns and set of weft yarns are substantially perpendicular to each other. The set of warp yarns are periodically interlaced with the set of weft yarns to form the woven ground fabric 106. The woven ground fabric 106 may be a plain or twill weave construction.
The pile-weave portions 102 include a plurality of pile yarns 102A, and the flat weave portions 104 include a plurality of yarns 104A. As illustrated in FIG. 2, the pile yarns 102A and yarns 104A extend outwardly from at least one surface of the woven ground fabric 106. In the present embodiment, the yarns 102A extend further from the surface of the ground fabric 106 than the yarns 104A. Alternatively, the flat-weave portions 104 may not include yarns 104A, instead comprising the portions of the woven ground fabric 106 that do not have the pile yarns 102A extending therefrom. In yet another alternative, the pile yarns 102A and/or yarns 104A include yarns that extend varying distances from the woven ground fabric 106.
The pile yarns 102A and/or yarns 104A may be formed as additional warp yarns interspersed between the ground warps and interlaced with the weft yarns as known in the art, such that the yarns are tied into the woven ground fabric 106. “Pile” are raised loops or cut loops that form a surface of a pile fabric. A pile fabric is a fabric having tufts protruding from a backing, such as the woven ground fabric 106. In the present embodiment, the pile yarns 102A extend from the ground fabric in the form of one or more terry loops. The yarns 104A can also extend from the ground fabric in the form of one or more terry loops. As illustrated in FIG. 2, the terry loop yarns 104A may comprise a substantially wider loop than the terry loop yarns 102A. Alternatively, the pile yarns 102A and/or yarns 104A may extend from the woven ground fabric 106 in the form of cut ends. The pile yarns 102A of the quick-dry textured towel 100 comprise low-twist yarn. The low-twist yarn may be zero twist yarn. In the depicted embodiment, the pile yarns 102A comprise a zero twist terry yarn. The textured weave design opens up the terry loops to facilitate faster drying.
The quick-dry textured towel 100 comprises any suitable material. In the present embodiment, the towel 100 comprises substantially all cotton, for example, 100% cotton. The towel 100 may comprise other materials, such as polyester or rayon. Alternatively, the quick-dry textured towel 100 comprises one or a combination of combination of cotton, polyester, rayon, silk, wool, and/or other suitable man-made and/or natural materials.
In summary, the quick-dry textured towel 100 includes a lightweight fabric including a plurality of low-twist pile yarns in a texture weave design. The lightweight fabric includes a fabric weight of less than about 350 g/m2. It has been observed that a direct relationship exists between a weight of a towel and its dry rate. For example, Table 1 below compares the quick-dry textured towel 100 of the present disclosure to commercially available towels.

Table 1 provides a dry time, fabric weight, and total size of each towel. The dry time represents the total time required for the towel to dry in minutes. The fabric weight, illustrated in grams per square meter of towel (g/m2), is determined from the total weight and total size of the towel. The total size for the towel represents the length and width of the towel in inches. As evident from Table 1, the quick-dry textured towel exhibits one of the quickest drying times (e.g., 20 minutes) while maintaining the lightest fabric weight (e.g., 345 g/m2). It should be noted that from Table 1 above that while the fabric weight (g/m2) for Towel 1 and 2 are similar, the size, hand feel, loft, bulk, and absorbency of the quick-dry textured towel 100 is superior and significantly different from Towels 1 and 2.
Table 2 below also compares the quick-dry textured towel 100 of the present embodiment to commercially available towels, specifically providing test results related to a weight of each towel while drying.
