The present disclosure relates to a flexible, bulk-free, resilient band for an article of apparel, and more particularly, relates to forming the resilient band by joining a first sheet of fabric to a second, more resilient, thin sheet of fabric to form a waistband and the like.
Resilient bands, such as waistbands, wristbands, and the like, are commonly used on articles of apparel, such as pants, jackets, and the like, to snugly secure the article of apparel to the wearer.
In general, these bands should snugly synch the article of apparel to the wearer, but remain flexible enough so as to not limit the wearer's full range of movement or feel too tight by the wearer. In addition, it is often desirable for the band to be as thin as possible so as to prevent the band from feeling bulky by the wearer. For example, waistbands on yoga pants must be particularly flexible and bulk-free, yet still secure the pants to the wearer throughout the wearer's full range of motion.
Known waistbands and the like tend to inadvertently compromise, comfort, fit, or the range of motion of the wearer. For example, a commonly used waistband design includes sewing a relatively thick elastic band to a strip of outer fabric to form one or more substantially horizontal seams. While effective as a waistband, this structure tends to feel bulky and not particularly resilient, and it tends to limit the range of motion of the wearer, particularly when used in yoga apparel. Moreover, elastic bands tend to lose some of their elasticity with repeated use over time.
Accordingly, despite the benefits of known resilient band structures used on articles of apparel, there remains a need for a cost effective, durable, light weight, bulk-free resilient band that allows a full range of movement of the wearer without compromising the ability of the band to hold onto its wearer.
The present invention overcomes these and other shortfalls with the known resilient band structures. A resilient band for use with articles of apparel that is formed with a first fabric operably secured to a more resilient elastic, and preferably fabric, structure is disclosed.
Disclosed preferred embodiment includes the fabric and elastic structure first being placed in a stretched position along their longitudinal lengths. They are then operably secured together with fastening structures that are preferably aligned substantially perpendicular to their longitudinal lengths. The resulting resilient band is extremely flexible and comfortable while still allowing it to effectively grasp the wearer throughout the entire range of movement of the wearer.
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features. Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

A resilient band 10 for an article of apparel 12, the band 10 formed with a sheet of first fabric 14 being operably secured to a more resilient sheet of second fabric 16, is shown in
Referring to
The first fabric 14 is preferably a soft, stretchy fabric, such as fleece or the like, that may also form an outer surface 20 of the article of apparel 12. For example,
The second fabric 16 is selected from a group of fabrics that are more resilient than the first fabric 14. It is preferable to encircle the first fabric 14 around the second fabric 16 as best shown in
Preferably, the powermesh fabric used as the second fabric 16 is composed of 70 to 90 percent nylon or polyester with the corresponding remaining material comprising spandex. More preferably, the powermesh fabric is warp knit mesh construction formed of 75 to 85 percent nylon or polyester with the remaining material comprising spandex. Even more preferably, the powermesh fabric is formed of less than 20 percent spandex such as 81 percent nylon or polyester and 19 percent spandex.
Other materials having the general elasticity, resiliency, and light fabric weight of powermesh may also be used. These fabric properties are preferably within the following ranges: Fabric weight of 180 grams per meter squared plus or minus 10 percent, and using the stretch recover properties defined by an industry standard test known as ASTM D2594, the resiliency, or “growth properties,” of the fabric in the length (wales) direction is preferably equal to a maximum 10 percent, with the width (courses) direction equal to a maximum of 5 percent. The corresponding desired elasticity using a 10 pound stretch property test is preferably between 80 to 100 percent in the length (wales) direction, and between 40 to 60 percent in the width (courses) direction.
The first and second fabrics 14, 16, respectively, are operably secured together so as to not unduly limit the stretchability of the resulting resilient band 10 in all directions. For example, and as shown in
Preferably, the first and second fabrics 14, 16 are secured together so as to prevent a substantial continuous seam parallel to the longitudinal length 30 of the resilient band 10. For example, the first and second fabrics 14, 16 may be stitched together with a plurality of spaced-apart, substantially parallely-aligned stitches 40 that may be aligned substantially vertically and perpendicular to the longitudinal centerline 30 of the resilient band 10 as shown in
The resulting stitching pattern will allow the first and second fabrics 14,16 to rest substantially parallel to each other in the stretched position Y shown in
More preferably, the stitching may follow a substantially continuous serpentine pattern 36 along the longitudinal length 30 of the resilient band 10 with cross-over stitching 38 alternating which end to cross-over to the next substantially vertical parallel line 40 of stitching so as to prevent a substantially continuous horizontal seam along the longitudinal length 30 of the resilient band. Even more preferably, the horizontal cross-over stitching 38 extends between two adjacent, substantially vertical and parallel stitching lines 40, with the horizontal cross-over stitching 38 being vertically spaced apart from adjacent cross-over stitching 40 so as to not impede the longitudinal stretching of the resulting resilient band 10, particularly in the direction of the stretched position Y shown in
Referring to
If desired, the draw string 18 may be operably received in the internal pocket 56 with the ends of the draw string 18 extending through openings 58 (
Referring to
If desired, the draw string 18 may be operably received within the internal pocket 56 of this configuration as previously shown and described.
The resulting resilient band 10 is bulk free and easily flexible in all directions, including along the longitudinal length 30 of the band, while still offering superior holding ability through the entire range of motion of the wearer.
The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention. For example, although the disclosed first fabric 14 is described as also serving as the fabric for forming the article of apparel 16, the resilient band 10 of the present invention may be a discrete structure that is separate from the article of apparel 12 to which it is attached. Similarly, the article of apparel may not be a pair of paints, but a jacket or the like with the resilient band forming a wrist-strap, waist strap or the like thereon.
Also, the stitching methods and structures for securing the two fabrics 14, 16 together are for exemplary purposes only. Other securing methods, such as heating, using adhesives, and the like may also be used so long as the resulting securing structures do not unduly limit the range of movement of the resulting resilient band 10 as described. In addition, the disclosed parallely-aligned patterns for securing the two fabrics 14, 16 together need not form straight lines nor be aligned substantially perpendicular to the longitudinal length 30 of the resilient band 10.
Similarly, individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the invention, and all such modifications are intended to be included within the scope of the invention.
