Detailed Description

The utility model is further described with reference to the following figures and specific examples.

Example one

This embodiment will be described in detail with reference to fig. 1. The waterproof fabric for the garment comprises a fabric base layer 1, a nanometer chromogenic film layer 2 and a heat-insulating fabric layer 3; the nano chromogenic film layer 2 is a nano film layer which is generated by sputtering on the surface of the fabric base layer 1 by adopting a vacuum deposition technology; the warm-keeping fabric layer 3 is compounded on one side of the fabric base layer 1 far away from the nano chromogenic film layer 2 through an adhesive.

Nanometer color generation refers to sputtering a nanometer film layer on the surface of a fabric by using a vacuum deposition technology, and the interference, diffraction and scattering of natural light on the film can generate thousands of colors by adjusting the structure and the material of the film layer. The nanometer chromogenic film layer 2 is composed of nanometer particles, gaps exist among the particles, and gaseous water molecules can smoothly penetrate through the gaps, so that the nanometer chromogenic film layer improves the waterproof performance of the fabric, and does not have great influence on the air permeability and the moisture permeability of the fabric.

The fabric base layer 1 is a cotton high-density fabric, the cotton high-density fabric is a pure cotton fabric with high warp and weft densities, for example, pure cotton yarns with the fineness of 14.5tex are used as warp and weft yarns, the warp and weft densities are 523.5 pieces/10 cm and 283 pieces/10 cm respectively, and the pure cotton fabric is formed by interweaving two-over-one twill or plain weave.

The warm-keeping fabric layer 3 is formed by interweaving hollow terylene/Viloft blended yarns and aerogel fiber yarns according to a three-primary structure or other single-layer structures. Specifically, in the present embodiment, the fabric is woven in a plain weave.

Viloft (Viloft) fiber is a novel wood pulp cellulose fiber produced by Acordis, and meets the requirements of bionic environment protection. The section of the fabric is unique flat, the flatness is more than 5: 1, and the moisture and sweat on the surface of the skin can be discharged to the outside of the body through the capillary effect formed by the fine grooves and holes on the surface of the fiber through the actions of wicking, diffusion, transmission and the like, so that the skin can breathe freely. The Viloft fibers have good warmth retention and comfort properties. If the yarn is blended with other fibers with circular cross sections, unique moisture-conducting channels can be formed in the yarn body, and the yarn body has excellent wicking and moisture conditioning functions. The Viloft fiber has good strength, elasticity, heat preservation and antistatic performance and good blending and dyeing performance. In the embodiment, Viloft fibers and hollow polyester fibers are mixed, medium-length Viloft fibers and hollow polyester fibers are blended to form yarns, the fineness of the Viloft fibers is 2.22dtex, the fiber length is 51mm, the breaking strength is 2.56cN/dtex, and the elongation at break is 25%; the fineness of the hollow polyester fiber is 2.67dtex, the fiber length is 57mm, the breaking strength is 4.87cN/dtex, and the elongation at break is 32%. In this example, the blend ratio of hollow polyester/Viloft is 65/35. Considering that the product is a warm-keeping fabric and belongs to medium-thickness wool-like fabrics, the yarn is designed to be single yarn with the yarn number of 18.45tex, Z twist and the twist of 750/m. And the single yarns are plied and twisted into a ply yarn for production, and the final finished yarn specification is 18.45tex multiplied by 2, S twist and twist number 600 twist/m.

The nano chromogenic film layer 2 comprises a nano antibacterial film layer 21 and a titanium dioxide film layer 22 in sequence; the nano antibacterial film layer 21 is adjacent to the fabric base layer 1. The nanometer color generation technology realizes the unification of color generation and antibiosis by selecting film layer materials, and develops a thought for the research of the antibacterial fabric. In order to improve the antibacterial performance of the nano chromogenic fabric, a nano antibacterial film layer 21 formed by nano silver or nano zinc oxide is superposed with a loose titanium dioxide film layer 22, the antibacterial function of silver or zinc ions is mainly utilized, and meanwhile, the loose titanium dioxide film layer is added to protect a silver/zinc functional layer, so that the release of the silver/zinc ions is delayed, and the action time of the antibacterial function of the fabric is prolonged.

Further, polyester aerogel fibers are used in the aerogel fiber yarns. The aerogel fiber is prepared by ultrasonically dispersing nano titanium dioxide powder into a mixed solution of ethanol and glycol, adding silica aerogel and a silane coupling agent under the condition of high-speed stirring, uniformly mixing, fully reacting, and drying to obtain aerogel pretreatment powder; blending and melting the aerogel pretreatment powder and PET plastic to obtain spinning; and stretching the spinning, and then drying to obtain the aerogel fiber. The formed aerogel in the polyester aerogel has good dispersibility in fibers, and has good warm-keeping effect through tests, so that the jean fabric can better exert the warm-keeping and cold-proof performances in cold winter. The fineness of the formed aerogel fiber is 1.5-2D, and the length is 38-51 mm.

Example two

This embodiment will be described in detail with reference to fig. 2. The waterproof fabric for clothing according to the embodiment is different from the first embodiment in that: the warm-keeping fabric related to the embodiment is formed by interweaving double-layer binding tissues, wherein the warp yarns are hollow terylene/Viloft blended yarns, and the weft yarns are aerogel fiber yarns.

Specifically, in this embodiment, the warp includes a surface layer warp and an inner layer warp, the surface layer warp includes a surface layer first warp 301, a surface layer second warp 302, a surface layer third warp 303, and a surface layer fourth warp 304, the inner layer warp includes an inner layer first warp 401, an inner layer second warp 402, an inner layer third warp 403, and an inner layer fourth warp 404, the weft includes a surface layer weft and an inner layer weft, the surface layer weft includes a surface layer first weft 311, a surface layer second weft 312, a surface layer third weft 313, and a surface layer fourth weft 314, and the inner layer weft includes an inner layer first weft 411, an inner layer second weft 412, an inner layer third weft 413, and an inner layer fourth weft 414. The surface layer warp yarns and the surface layer weft yarns are interwoven to form a surface layer, and the inner layer warp yarns and the inner layer weft yarns are interwoven to form an inner layer.

Taking weft as a reference, the floating and sinking rule of the first surface layer warp yarn 301 is floating-sinking-floating-sinking-floating, the floating and sinking rule of the first inner layer warp yarn 401 is sinking-floating-sinking, the floating and sinking rule of the second surface layer warp yarn 302 is sinking-floating-sinking-floating, and the floating and sinking rule of the second inner layer warp yarn 402 is sinking-floating-sinking; the floating-sinking rule of the third warp yarn 303 on the surface layer is floating-sinking-floating-sinking-floating, and the floating-sinking rule of the third warp yarn 403 on the inner layer is sinking-floating-sinking; the floating and sinking rule of the fourth warp yarn 304 on the surface layer is sinking-floating-sinking-floating, and the floating and sinking rule of the fourth warp yarn 404 on the inner layer is sinking-floating-sinking-floating. Wherein floating means that the warp yarn is above the weft yarn and sinking means that the warp yarn is below the weft yarn. The double-layer weave increases the thickness of the fabric and improves the heat preservation performance of the fabric. By using the Viloft fibers, the air permeability and the moisture permeability of the fabric are far higher than those of the fabric with a single-layer structure.

The foregoing detailed description of the preferred embodiments of the utility model has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection determined by the claims.
