[0031] Embodiment
[0032] Please refer to Figure 1 As shown, the present utility model discloses a waterproof fabric, which includes a surface layer 100, a waterproof layer 200 and a skin-friendly layer 300 connected in sequence.
[0033] Among them, the surface layer 100 is a PRECYCLE fabric with a plain weave design; the waterproof layer 200 is a Jielei film, which is compounded between the surface layer 100 and the skin-friendly layer 300 to play a waterproof role, and the skin-friendly layer 300 adopts a woven structure.
[0034] For details, please refer to Figure 2 As shown, the skin-friendly layer 300 includes a plurality of weaving units 310 connected in sequence, and each weaving unit 310 is woven by a plurality of warps and a plurality of wefts. Among them, the plurality of warps and the plurality of wefts include thermal insulation fibers 311, antibacterial fibers 312, antistatic fibers 313 and at least one pair of elastic fibers 314, and the pair of elastic fibers 314 constitutes the frame of the weaving unit 310, and the thermal insulation fibers 311, antibacterial fibers 312, and antistatic fibers 313 are woven in the frame, and the thermal insulation fibers 311 and the antibacterial fibers 312 are woven adjacent to each other.
[0035] The utility model is woven by a pair of elastic fibers 314 in the warp direction and a pair of elastic fibers 314 in the weft direction to form a frame of the weaving unit 310, which is conducive to improving the elasticity of the fabric and enhancing the skin-friendly feeling, while maintaining a certain degree of stiffness of the fabric through the elastic fibers 314. The functional fibers are woven in the frame to improve the elasticity of the skin-friendly layer 300, thereby improving the skin-friendly feeling; at the same time, the functional fibers of the utility model take into account warmth preservation, antibacterial and antistatic properties, enriching the fabric functions.
[0036] In each weaving unit 310 of the utility model, the thermal insulation fibers 311 in the warp and weft directions are a pair. The thermal insulation fibers 311 are soft in texture and are arranged in the skin-friendly layer 300, which not only plays a role in warmth and breathability, but also improves the skin-friendly feeling. The antibacterial property of the thermal insulation fibers 311 is generally poor and is easily eaten by insects. Therefore, in the utility model, the antibacterial fibers 312 are woven into a pair of thermal insulation fibers 311 in both the warp and weft directions to improve the antibacterial effect.
[0037] Please refer to Figure 2 As shown, in the utility model, there are six warps and six wefts, which are, from left to right, the first warp, the second warp, the third warp, the fourth warp, the fifth warp and the sixth warp; and from top to bottom, the first weft, the second weft, the third weft, the fourth weft, the fifth weft and the sixth weft.
[0038] Specifically, the first warp, the sixth warp, the first weft and the sixth weft are all configured as elastic fibers 314, the second warp, the fourth warp, the second weft and the fourth weft are all configured as thermal insulation fibers 311, the third warp and the third weft are configured as antibacterial fibers 312, and the fifth warp and the fifth weft are configured as antistatic fibers 313. Through the reasonable distribution of each warp and weft, each weaving unit 310 achieves a comprehensive effect among elasticity, warmth, antibacterial and antistatic.
[0039] Please refer to Figure 2As shown, in the present utility model, the weave points of the first warp are warp one-down two-up one-down two-up, the weave points of the second warp are warp two-down one-up two-down one-up, the weave points of the third warp are warp one-up two-down one-up two-down, the weave points of the fourth warp are warp one-down one-up two-down one-down one-up, the weave points of the fifth warp are warp one-up one-down two-up one-down one-up, and the weave points of the sixth warp are warp one-down two-up one-down two-up.
[0040] The elasticity of the antibacterial fiber 312 and the antistatic fiber 313 is generally less than that of the thermal insulation fiber 311. Through this structure, the antibacterial fiber 312 and the antistatic fiber 313 obtain longer warp floats or weft floats, increasing the elasticity of the skin-friendly layer 300. At the same time, it does not affect the contact between the thermal insulation fiber 311 and the skin, ensuring the skin-friendly feeling and the thermal insulation effect.
[0041] Please refer to Figure 3 As shown, in a preferred embodiment, the distance between adjacent wefts is greater than the distance between adjacent warps, that is, the weaving density of the wefts in the weaving unit 310 is less than the weaving density of the warps. In this way, the weft elasticity is improved, the sense of restraint is reduced, and the skin-friendly feeling is enhanced. In a feasible embodiment, the warp density is 120 - 130 threads / dm, and the weft density is 100 - 110 threads / dm.
[0042] The thermal insulation fiber 311, antibacterial fiber 312, antistatic fiber 313, and elastic fiber 314 described in the present utility model can adopt commercially available products, and the present utility model does not make specific limitations. In a feasible embodiment, the thermal insulation fiber 311 of the present utility model is a wool fiber, the antistatic fiber 313 is a carbon fiber, the antibacterial fiber 312 is a copper ion-modified polyacrylonitrile fiber yarn, and the elastic fiber 314 is a polyester fiber. It has good elastic recovery force and strong anti-destruction ability, will not deform, and improves the anti-deformation force of the fabric used.
[0043] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
