High-shrinkage three-dimensional wrinkled texture embossed knitted thermal composite fabric and preparation method thereof

Abstract

The invention discloses a high-shrinkage three-dimensional wrinkled texture embossed knitted thermal composite fabric. The composite fabric comprises an inner layer (1), a liner layer (2), a fabric layer (3) and an outer layer (4) which are sequentially connected together by connecting filaments from the interior to the exterior, and is prepared by performing after-treatment on the layers, wherein the inner layer (1) is composed of hygroscopic yarns and cotton yarn fibers; the liner layer (2) is composed of high-shrinkage polyacrylonitrile fibers, high-shrinkage polypropylene fibers and cotton-yarn braiding; the fabric layer (3) is formed by inter-looping silver-based antibacterial polyester fiber yarns and Spandex yarns; the outer layer (4) is composed of hygroscopic yarns and high-shrinkage cationic modification polyester fibers. The knitted composite fabric disclosed by the invention is sturdy in texture, soft in hand feeling, enriched in elasticity, excellent in thermal effect, low in fading possiblity, high in good in wrinkled texture and wear resistance, excellent in stereoscopic impression and obvious in texture embossing effect, has simple preparation process and low cost, and has excellent application prospects.

Description

Technical field [0001] The invention belongs to the technical field of knitted fabrics, and in particular relates to a high-shrinkage three-dimensional wrinkle texture relief warmth-keeping knitted composite fabric and a preparation method thereof. Background technique [0002] The air-layer warm fabric is called a healthy fabric in China, and it is called TechnicalFleece abroad. It is a special double-sided fabric structure. It is made by increasing the machine cylinder pitch and using a special knitted fabric technology to make the fabric double There is a large gap in the middle of the surface, so as to achieve the warmth preservation effect. At the same time, the fabric is light, soft and clean. It is a good autumn and winter warm fabric. However, most of the existing air layer thermal insulation fabric fibers are made for comfort, and the material of the fabric is made relatively soft, but although the comfort has been greatly improved, the texture of the fabric has also bee...

AI Technical Summary

Problems solved by technology

But most of the existing air layer thermal fabric fibers are designed to make the material of the fabric softer in order to consider the comfort, but although the comfort has been greatly improved, the texture of the fabric has also declined, making the fabric The texture of the fabric becomes thinner, the heat preservation effect becomes worse, and the wrinkle resistance and wear resistance are also greatly reduced. The fabric is easy to diverge, sparse, wrinkle and break after wearing it several times

In addition, due to the thin texture, the dyeability is also reduced, and the color depth of the fabric cannot be effectively guaranteed, and it is very easy to lose color and fade.
