A sandwich structure thermal fabric with high dimensional stability

Abstract

The invention relates to the field of special functional fabrics, and relates to a sandwich structure thermal fabric with high dimensional stability. The fabric is a woven and knitted composite fabric, including an inner layer woven structure, a middle knitted structure and a surface layer woven structure; the inner layer The woven structure is woven from the inner warp and the inner weft; the middle knitted structure is woven from looped yarn; the middle knitted structure adopts weft flat stitch structure, and the looped yarn is respectively connected with the surface woven structure and the inner woven structure . The present invention effectively combines the knitted structure and the woven structure to form a three-dimensional fabric structure of woven-knitted-woven, which has high dimensional stability, smooth and smooth touch on both sides, and good wrinkle resistance. The knitted structure is added to make the fabric body more fluffy and soft, with better warmth retention effect and good 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 ...

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
