Description

Technical Field

[0001] The present invention relates generally to woven straps and fabrics, and more particularly to multi-layer woven components suitable for use as straps for helmets or other similar articles. Background Art

[0002] The chin strap is an integral part of a safety helmet and headgear designed to secure the helmet in place and provide additional protection against head injuries. The chin strap typically consists of a band that wraps around the wearer's chin and attaches to the side or back of the helmet. The chin strap is made of a soft yet durable material to minimize irritation or discomfort during extended wear. Conventional chin straps for safety helmets are typically made from mono-component yarns with a simple plain weave structure. These mono-component yarns have poor moisture management properties. Consequently, a chin strap with poor moisture management can trap sweat on the wearer's skin, causing discomfort, irritation, and skin irritation. This is particularly problematic during physical activity or in hot and humid environments where sweating is common.

[0003] The inventors have identified many improvements over the prior art and methods, which are the subject of the embodiments described herein. Through applied effort, creativity, and innovation, many of these deficiencies, challenges, and problems have been addressed by developing solutions included in the embodiments of the present disclosure, some examples of which are described in detail herein.

However, the claimed embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. The examples set forth herein are non-limiting examples and are merely examples of other possible examples.

[0031] The present disclosure provides embodiments of multi-layer woven components for dissipating moisture from a wearer's skin surface (e.g., face, scalp, etc.). Embodiments can be configured to have a first side adapted to contact a user's skin surface. The first side includes a plurality of first-type yarns and a plurality of second-type yarns. Embodiments can be configured such that the plurality of first-type yarns in the first side predominate over the plurality of second-type yarns in the first side. Embodiments can be configured such that the second side is opposite the first side, the second side including at least a portion of the plurality of second-type yarns.

[0032] Figure 1 Shown is a cross-sectional view of a multi-layer knitted component 100 according to an exemplary embodiment of the present disclosure.

[0033] In some embodiments, multi-layer knitted component 100 may have a first side 102 and a second side 104. In some embodiments, first side 102 of multi-layer knitted component 100 may be adapted to contact a user's skin surface. Furthermore, second side 104 of multi-layer knitted component 100 may be opposite first side 102 of multi-layer knitted component 100. In some embodiments, first side 102 may further include a plurality of first-type yarns 106 and a plurality of second-type yarns 108. In some embodiments, first-type yarns 106 may predominate over second-type yarns 108 in first side 102.

[0034] like Figure 1 As shown, a plurality of first type yarns 106 may form small gaps that may have passageways for a plurality of second type yarns 108. A plurality of first type yarns 106 and a plurality of second type yarns 108 may be arranged alternately with each other. In some embodiments, first side 102 of multi-layer knitted component 100 may be arranged such that a plurality of first type yarns 106 may predominate over a plurality of second type yarns 108. In some embodiments, the ratio between a plurality of first type yarns 106 and a plurality of second type yarns 108 may vary between 3:1, 4:1, 2:1, and the like. However, a plurality of first type yarns 106 may always be greater than a plurality of second type yarns 108.

[0035] In some embodiments, the plurality of first type yarns 106 may include hydrophobic yarns. In addition, the plurality of second type yarns 108 may include hydrophilic yarns or yarns that are less hydrophobic than the plurality of first type yarns 106 (for simplicity, the first type yarns that are hydrophilic or less hydrophobic than the second type yarns will be simply referred to as "hydrophilic" herein). In some embodiments, the plurality of first type yarns 106 may be multifilament yarns, staple yarns, and low moisture regain yarns. The first type 106 may be treated with a hydrophobic treatment to obtain hydrophobic properties. Therefore, the hydrophobic properties allow less absorption / transfer / retention of moisture in the plurality of first types 106 compared to the plurality of second types 108. In addition, the first type 106 may be treated with auxiliary finishing, shaped fibers, and grafting modifications. In some embodiments, the grafting modifications include polyester, nylon, polypropylene, and the staple yarns include cotton and viscose.

[0036] In some embodiments, the second type 108 can be a multifilament yarn, a staple yarn, and a low moisture regain yarn. The second type 108 can be treated with a hydrophilic treatment to obtain hydrophilic properties. Therefore, the hydrophilic property allows for greater absorption / transfer / retention of moisture in the plurality of second types 108. In addition, the second type 108 can be treated with auxiliary finishing, shaped fibers, and grafting modifications. In some embodiments, the grafting modification includes polyester, nylon, and polypropylene, and the staple yarn includes cotton and viscose. In some embodiments, the plurality of second type yarns 108 including hydrophilic yarns or yarns that are less hydrophobic than the plurality of first type yarns 106 can facilitate the transfer of moisture from the first side 102 of the multi-layer woven component to the second side of the multi-layer woven component.

[0037] In some embodiments, plurality of first type yarns 106 and plurality of second type yarns 108 can facilitate the creation of a potential difference between first side 102 of the multi-layer knitted component and second side 104 of the multi-layer knitted component. Furthermore, the created potential difference can enable moisture droplets 110 received from the user's skin to be transferred from first side 102 of multi-layer knitted component 100 to second side 104. The hydrophilic nature of plurality of second type yarns 108 causes moisture droplets 110 to flow from first side 102 to second side 104 via channels through plurality of second type yarns 108.

[0038] In some embodiments, second side 104 may include at least a plurality of second type yarns 108. Second type yarns 108 are adapted to wick moisture from first side 102 of multi-layer knitted component 100 and evaporate moisture received from first side 102 of multi-layer knitted component 100 to the environment. In an exemplary embodiment, second side 104 includes only plurality of second type yarns 108. In another exemplary embodiment, second side 104 includes both plurality of first type yarns 106 and plurality of second type yarns 108, but plurality of second type yarns 108 predominate over plurality of first type yarns 106.

[0039] Figure 2 A top view of knit structure 200 in a multi-layer knitted component is shown according to an exemplary embodiment of the present disclosure. Figure 3 Cross-sectional views of weft and warp yarns in various exemplary patterns of multi-layer knitted components according to exemplary embodiments of the present disclosure are shown.

[0040] In some embodiments, a plurality of first type yarns 106 and a plurality of second type yarns 108 can be woven as weft yarns 202 and warp yarns 204, respectively, in first side 102 and second side 104 of a multi-layer knitted component. Figure 2 As shown, the weft yarns 202 and the warp yarns 204 can be woven such that the weft yarns 202 are perpendicular to the warp yarns 204. The weft yarns 202 and the warp yarns 204 can alternately float intersections 206 on the first side 102. In some embodiments, the intersections 206 can be points where the weft yarns 202 intersect with the warp yarns 204. In an exemplary embodiment, the weft yarns 202 and the warp yarns 204 can be hydrophobic yarns or hydrophilic yarns.

[0041] In some embodiments, the plurality of first type yarns 106 and the plurality of second type yarns 108 may be woven into weft yarns 202 and warp yarns 204 in a variety of combinations.
