High-dimensional-stability warm-keeping fabric with sandwich structure

Abstract

The invention relates to the field of special functional fabrics, in particular to a high-dimensional-stability warm-keeping fabric with a sandwich structure. The high-dimensional-stability warm-keeping fabric with a sandwich structure is a woven and knitted composite fabric, and comprises an inner layer woven structure, a middle knitted structure and a surface layer woven structure; the inner layer woven structure is formed by weaving inner warps and inner wefts; the middle knitted structure is formed by knitting looping yarns; the middle knitted structure is provided with a weft plain stitchstructure, and the looping yarns are respectively connected with the surface layer woven structure and the inner layer woven structure. According to the invention, the knitted structure and the wovenstructures are effectively combined to form a woven-knitted-woven three-dimensional fabric structure, the dimensional stability is high, surface and inner surface touch feel is smooth and fresh, thecrease resistance is excellent, and the knitted structure is added between the inner and outer woven structures, so that the fabric body is more fluffy and softer, better in warm-keeping effect and good in air permeability.

Description

technical field [0001] The invention belongs to the field of special functional fabrics and relates to a sandwich structure thermal fabric with high dimensional stability. Background technique [0002] Woven structure and knitted structure are two traditional textile structures, each with advantages and disadvantages. In the woven structure, since the warp and weft exist in an approximately straight line, they exhibit better structural stability, less extensibility, and lower elasticity when subjected to external forces. Difficult to delamination, smooth and smooth surface, good wrinkle resistance, but poor formability; in the knitted structure, because the yarn mainly exists in the form of coils, when subjected to external force, the coils can be deformed and the yarn can slip , showing greater extensibility and higher elasticity, good formability, but poor structural stability. If the two structures are combined, the defects of the single structure will be overcome, and ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides a high dimensional stability thermal fabric of sandwich structure, through the composite fabric structure of weaving-knitting-woven, the organic structure of weaving and knitting solves the problem of existing woven fabrics. Fabrics and knitted fabrics have their own shortcomings, lack of corresponding new fabrics that combine woven fabrics and knitted fabrics, single structure, and unsatisfactory thermal insulation effect
