Technical Field

The invention belongs to the technical field of knitted fabrics, and particularly relates to a quick moisture absorption and sweat releasing double-faced knitted fabric, and a preparation method and application thereof.

Background

The clothing fabric is mainly woven and knitted fabric, wherein the knitted fabric is continuous fabric with certain width formed by looping and stringing one or more composite yarns, and has the characteristics of high speed and high efficiency.

Polyester fiber, commonly known as "polyester", is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dihydric alcohol, is called PET fiber for short, and belongs to a high molecular compound. Invented in 1941, is the first major variety of current synthetic fibers. The polyester fiber has the advantages of good crease resistance and shape retention, high strength and elastic recovery capability, firmness and durability, crease resistance, no ironing and no hair sticking. The terylene is used as the fiber for clothes, and the fabric of the terylene has the effects of no wrinkle and no ironing after washing.

The Viscose yarn (spun rayon) takes Viscose fiber (Viscose) as a raw material, is one of artificial cotton yarns, has good hand feeling, is smooth and is comfortable to wear. Because of good moisture absorption, comfortable wearing and excellent spinnability, the viscose yarn is often blended and interwoven with cotton, wool or various synthetic fibers and is used for various clothes and decorative textiles.

With the improvement of living standard, the requirements of sports clothes on moisture absorption and sweat releasing are gradually improved, the existing fabric cannot usually release sweat and dry quickly when having better moisture absorption performance, and the existing fabric is easy to cling to the skin after absorbing sweat, so that the feeling of stuffiness and dampness and the feeling of constraint are caused.

For the problem of improving the moisture absorption and sweat releasing performance of the knitted fabric, the following methods are generally adopted in the prior art: chinese patent 202020055264.8 proposes to adopt three kinds of yarns to make the moisture absorption and sweat releasing woven fabric by interweaving, Chinese patent 202010676677.2 proposes to adopt AB yarn to interweave to make the moisture absorption and sweat releasing woven fabric; chinese patent 201921705397.9 adopts a woven fabric to make the moisture-absorbing and sweat-releasing fabric, but the three still have the problems that the fabric application range is limited, the fabric is not suitable for sports clothes and the like. Patent 202010170778.2 proposes sewing a moisture-wicking undergarment using different fabrics. But still has the problems of complex tailoring, complex garment making process and the like. Patent 201810767423.4 proposes that a double-faced fabric with a one-way thread guiding function is prepared by adopting 3 different types of filaments through a double-faced knitting machine, but the problems that the filament garment coverage rate is low, the light transmission is strong, and the filament garment is not suitable for being used as close-fitting single-layer clothes and the like still exist.

Therefore, how to ensure that the knitted fabric meets the special requirements of moisture absorption and sweat releasing on the premise of the existing rapid preparation efficiency becomes a technical problem which needs to be solved urgently in the field.
