Auxetic textile structures
Apparatuses are described that provide for auxetic textile structures. An example auxetic textile structure includes an auxetic layer having an inner surface and an outer surface, wherein the auxetic layer comprises a plurality of high performance yarns. The auxetic textile structure further includes a plurality of dispersed elastic portions at least partially coupled to the inner surface of the auxetic layer, wherein the plurality of dispersed elastic portions in combination with the auxetic layer form a plurality of double layer structures distributed amongst a single layer of the auxetic layer. Each of the dispersed elastic portions comprises a plurality of elastic yarns.
1 . An auxetic textile structure comprising:
an auxetic layer having an inner surface and an outer surface, wherein the auxetic layer comprises a plurality of high performance yarns; and
a plurality of dispersed elastic portions at least partially coupled to the inner surface of the auxetic layer, wherein the plurality of dispersed elastic portions in combination with the auxetic layer form a plurality of double layer structures distributed amongst a single layer of the auxetic layer, and wherein each of the dispersed elastic portions comprises a plurality of elastic yarns.
2 . The auxetic textile structure of claim 1 , wherein the plurality of high performance yarns comprises one or more of ultra-high molecular weight polyethylene (UHMWPE), aramid, metal, glass, basalt, carbon, polybenzoxazole (PBO), polybenzimidazole (PBI), polyether ether ketone (PEEK), polyimide (PI), liquid crystalline polymer (LCP), polyphenylene sulfide (PPS), or a combination thereof.
3 . The auxetic textile structure of claim 1 , wherein the auxetic layer further comprises one or more of a synthetic yarn or a natural yarn.
4 . The auxetic textile structure of claim 1 , wherein the elastic yarns of the dispersed elastic portions have a lower modulus of elasticity than the high performance yarns of the auxetic layer.
5 . The auxetic textile structure of claim 1 , wherein the elastic yarns comprise one or more of spandex, rubber, thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), or a combination thereof.
6 . The auxetic textile structure of claim 1 , wherein the inner surface of the auxetic layer is visible between the plurality of dispersed elastic portions.
7 . The auxetic textile structure of claim 1 , wherein a void space is defined between each of the dispersed elastic portions and the auxetic layer in a first state of the auxetic textile structure.
8 . The auxetic textile structure of claim 7 , wherein the first state comprises an unstressed state devoid of external application of stress.
9 . The auxetic textile structure of claim 7 , wherein the void space is reduced in a second state of the auxetic textile structure.
10 . The auxetic textile structure of claim 9 , wherein the second state comprises a stressed state wherein an external stress is applied to the auxetic textile structure.
11 . The auxetic textile structure of claim 10 , wherein the plurality of dispersed elastic portions are configured to return the auxetic textile structure to the first state after the external stress is removed.
12 . The auxetic textile structure of claim 1 , wherein the auxetic layer comprises a plurality of auxetic segments, the auxetic segments oriented to impart auxetic properties to the auxetic layer.
13 . The auxetic textile structure of claim 12 , wherein the plurality of auxetic segments are disposed in a repeating pattern.
14 . The auxetic textile structure of claim 12 , wherein the pattern is an organized array of repeating bow-tie shaped segments.
15 . The auxetic textile structure of claim 13 , wherein the pattern is an organized array of repeating chevron-shaped segments.
16 . The auxetic textile structure of claim 12 , wherein the plurality of auxetic segments are inconsistently disposed throughout the auxetic layer.
17 . A cut-resistant sleeve comprising a plurality of auxetic textile structures according to claim 1 .
18 . A cut-resistant glove comprising:
one or more auxetic textile structures, wherein each of the auxetic textile structures comprise:
an auxetic layer having an inner surface and an outer surface, wherein the auxetic layer comprises a plurality of cut-resistant yarns; and
a plurality of dispersed elastic portions at least partially coupled to the inner surface of the auxetic layer, wherein the plurality of dispersed elastic portions in combination with the auxetic layer form a plurality of double layer structures distributed amongst a single layer of the auxetic layer, and wherein each of the dispersed elastic portions comprises a plurality of elastic yarns.
19 . The cut-resistant glove or sleeve of claim 18 , wherein at least one of the auxetic textile structures is disposed in a finger portion of the cut-resistant glove.
20 . The cut-resistant glove of claim 18 , wherein the cut-resistant glove further comprises a coating layer, the coating layer comprising one or more of nitrile rubber, natural rubber, polyurethane (PU) rubber, neoprene rubber, polyvinyl chloride (PVC) rubber, wax, latex, or a combination thereof.
