DETAILED DESCRIPTION
[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] Embodiment 1
[0021] Combination Figure 1 and Figure 2 , this embodiment is described in detail. The cotton-spandex elastic woven fabric involved in this embodiment is formed by interweaving warp yarns and weft yarns in a double-layer structure, characterized in that the warp yarns include surface warp yarns and inner warp yarns, and the weft yarns include surface weft yarns and inner weft yarns; the surface warp yarns and surface weft yarns are interwoven to form a surface layer 1, and the inner warp yarns and inner weft yarns are interwoven to form an inner layer 2.
[0022] The surface warp yarn and the surface weft yarn are made of the first elastic core-spun yarn, which includes a first elastic core yarn and a first covering fiber layer covering the outside of the first elastic core yarn; the first elastic core yarn is a degradable spandex filament, and the first covering fiber layer is a cotton fiber. Both the degradable spandex filament and the cotton fiber are degradable fibers, so that the surface layer 1 is degradable.
[0023] The inner warp yarn and the inner weft yarn use the second elastic core-spun yarn, which includes the second elastic core yarn and the first covering silk layer covering the outer side of the second elastic core yarn; the second elastic core yarn is a degradable polyester elastic filament, and the first covering silk layer is a PLA / PHBV fiber filament. PLA / PHBV fiber is a new type of biodegradable composite fiber formed by using corn starch to make glucose as the main raw material, culturing a selected microorganism in large quantities, and then extracting a polyester (poly 3-hydroxybutyrate-CO-3-hydroxyvalerate) in the microorganism—PHBV, and then blending and spinning with polylactic acid fiber. Combined with the degradable polyester elastic filament PBST used, the inner layer 2 is also degradable.
[0024] Furthermore, the cross section of the PLA / PHBV fiber filament is Y-shaped, cross-shaped or star-shaped. In this embodiment, the Y-shaped, i.e., clover-shaped, is selected. Since PLA / PHBV fiber is also polyester fiber, its hygroscopicity is poor, combined with the special-shaped cross section, it can have a moisture-conducting effect.
[0025] Furthermore, the surface warp yarns and the inner warp yarns are arranged in a 1:1 order, and the surface weft yarns and the inner weft yarns are arranged in a 1:1 order.
[0026] Specifically, the surface warp yarns include a first surface warp yarn 101, a second surface warp yarn 102, a third surface warp yarn 103, and a fourth surface warp yarn 104; the inner warp yarns include a first inner warp yarn 111, a second inner warp yarn 112, a third inner warp yarn 113, and a fourth inner warp yarn 114; the surface weft yarns include a first surface weft yarn 201, a second surface weft yarn 202, a third surface weft yarn 203, and a fourth surface weft yarn 204; the inner weft yarns include a first inner weft yarn 211, a second inner weft yarn 212, a third inner weft yarn 213, and a fourth inner weft yarn 214;
[0027] Taking the weft yarn as the standard, the floating and sinking rules of the warp yarn are as follows: the floating and sinking rules of the first surface warp yarn 101 are float-float-float-float-sink-float-sink-float-sink-float; the floating and sinking rules of the first inner warp yarn 111 are sink-float-sink-float-sink-sink-sink-sink-sink; the floating and sinking rules of the second surface warp yarn 102 are sink-float-float-float-float-float-sink-float; the floating and sinking rules of the second inner warp yarn 112 are sink-sink-sink-float-sink- Sink-float-sink-sink; the floating and sinking pattern of the third surface warp yarn 103 is sink-float-sink-float-float-float-float-float-float; the floating and sinking pattern of the third inner warp yarn 113 is sink-sink-sink-sink-sink-float-sink-float; the floating and sinking pattern of the fourth surface warp yarn 104 is float-float-sink-float-sink-float-float-float-float; the floating and sinking pattern of the fourth inner warp yarn 114 is sink-float-sink-sink-sink-sink-sink-float. The floating involved refers to the warp yarn being located on the upper side of the weft yarn, which is the warp tissue point, and the sinking is the weft tissue point.
[0028] Embodiment 2
[0029] The cotton-polyurethane elastic woven fabric involved in this embodiment is different from that in the first embodiment in that an antibacterial agent is attached to the surface of the cotton fiber.
[0030] Furthermore, another difference is that the outer side of the first wrapping fiber layer is wrapped with a second wrapping silk layer, and the second wrapping silk layer is ProModal filament. A second wrapping fiber layer is arranged between the second elastic core yarn and the first wrapping silk layer, and the second wrapping fiber layer is biodegradable polyamide 56 fiber. ProModal filament and polyamide 56 fiber are also biodegradable.
[0031] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
