Problems solved by technology

[0006] Chinese patent CN 1252344C (disclosure date 2006.4.19) discloses silk, wool fabric and its ready-made clothing shape memory agent and its application, including the condensation product of ethylene glycol and epichlorohydrin, polyethylene glycol and terephthalmic The water-soluble resin synthesized by the condensation of isocyanate is used in the shape memory finishing of silk, wool fabric and its ready-made garments, which can keep the concave-convex pattern of the fabric at a level of 4-5, but this method belongs to the post-finishing method, and the shape memory function can only be maintained. about a year
Chinese patent CN 103847160A (disclosure date 2014.06.11) discloses a striped brushed antibacterial anti-wrinkle fabric, which contains a fabric body, stripes and a brushed layer, wherein the fabric contains polyurethane material with a memory function, and the striped brushed antibacterial structure makes the fabric The surface shows a concave-convex structure, which enhances the three-dimensional effect of the fabric, but the fabric contains multi-layer technology, the preparation process is complicated, and the cost is high, so it is not suitable for industrial production
[0007] It can be seen from the above-mentioned prior art that the product forms of shape memory fabrics are currently limited, and shape memory fabrics are often added to conventional fabrics to give new functions to conventional fabrics. There are not many varieties of full shape memory fabrics, especially those with concave-convex three-dimensional Sensitive shape memory fabrics are even rarer

Embodiment 1

[0022] Such as figure 1 As shown, a shape-memory fabric with a concave-convex pattern includes warp threads and weft threads, the warp threads include ground warp and surface warp, and the weft threads include ground weft and surface weft.

[0023] The surface warp and surface weft are PTT fibers, and the surface warp and surface weft are woven with surface weave. The surface weave adopts a diamond-shaped weave with long floating length lines. The basic weave of the diamond-shaped weave is 11 / 33 twill, Rj=Rw=14, where The weft part is interwoven with the surface warp.

[0024] The ground warp and ground weft are natural cotton fibers, which are woven with the inner weave, and the inner weave adopts plain weave with a large warp and weft density.

[0025] Among them, the ground longitude and the ground latitude are one color, the surface longitude and the surface latitude are two colors, and the arrangement ratio of the surface longitude and the surface latitude is 2:1.

Embodiment 2

[0027] Such as figure 2 As shown, a shape-memory fabric with a concave-convex pattern includes warp threads and weft threads, the warp threads include ground warp and surface warp, and the weft threads include ground weft and surface weft.

[0028] The surface warp and surface weft are polyurethane fibers, and the surface warp and surface weft are woven with surface weaves. The surface weave adopts 8 composite twill weaves with long floating lines, and the surface wefts are all interwoven with the surface warp.

[0029] The ground warp and ground weft are natural hemp fibers, which are woven with the inner weave, and the inner weave adopts 1 / 2 right twill weave with a large warp and weft density.

[0030] Among them, the ground longitude and ground latitude are one color, the surface longitude and surface latitude are one color, and the arrangement ratio of surface longitude and surface latitude is 2:2.

Embodiment 3

[0032] Such as image 3 As shown, a shape-memory fabric with a concave-convex pattern includes warp threads and weft threads, the warp threads include ground warp and surface warp, and the weft threads include ground weft and surface weft.

[0033] The surface warp and surface weft are made of PTT fiber or polyurethane fiber. The surface warp and surface weft are woven with surface weave. The surface weave adopts 4 / 4 double flat weave with long floating length, and the surface weft is all interwoven with the surface warp.

[0034] The ground warp and ground weft are natural wool fibers, which are woven with the inner weave, and the inner weave adopts 2 / 2 right twill weave with a large warp and weft density.

[0035] Among them, the inner warp and the inner weft are one color, the outer warp and the outer weft are two colors, and the arrangement ratio of the outer warp and the outer weft is 2:2.

Abstract

The invention provides a shape-memory fabric with concave-convex patterns, including warp and weft, the warp includes the ground warp and the surface warp, the weft includes the ground weft and the surface weft, the ground warp and the surface weft adopt inner weave with a relatively large warp and weft density, and the surface warp The outer warp and weft yarns use shape memory fibers, the inner warp and weft yarns use conventional fibers, and the warp and weft yarns are woven into shape memory fabrics with concave-convex patterns by double weaving of warp and weft. The concave-convex feeling of the shape-memory fabric prepared by the method can be adjusted, the style is changeable, the pattern is unique, the hand feels three-dimensional, and the shape is permanently maintained.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a shape-memory fabric with concavo-convex patterns. Background technique [0002] Today, with the continuous evolution and updating of science and technology, people are pursuing more and more changes in the performance of fabrics. Shape memory fabrics have already entered people's field of vision and are looking for a market. [0003] The original memory fabric is a blended fabric woven with shape memory metal fibers. Because the metal fibers are easily broken after repeated washing and affect the comfort of the fabric, it is gradually eliminated by the market and replaced by a new shape. memory fabric. The new shape fabric has the luster of the original metal fabric, has a softer hand, is washable, and has permanent shape retention. [0004] The main component of the fabric is a two-phase copolymer with memory function, mainly PTT fiber, PET fiber and po...
