Warp knitted fabric containing cotton and processing method for warp knitted fabric

Abstract

The invention discloses a warp knitted fabric containing cotton. The warp knitted fabric containing the cotton is formed by face filaments and middle filaments or face filaments, middle filaments and bottom filaments in a warp knitting mode, wherein the face filaments are polyester filament yarns, the middle filaments are natural fiber yarns, the bottom filaments are spandex stretch yarns, and the natural fiber yarns are processed through spinning, singeing, reeling, concentrated alkaline mercerizing, drying, wet waxing, dry waxing, rewinding and the like. The natural fiber yarns have the advantages of being high in strength, even in yarn evenness, good in wear resistance and the like, and can meet the requirement of warp knitting, and thus the natural fiber yarns can be used on a 28-stitch high stitch length warp knitting machine to serve as raw knitting materials of the warp knitted fabric containing the cotton. The natural fiber yarns contained in the warp knitted fabric containing the cotton have the skin friendly performance, and the warp knitted fabric containing the cotton is suitable for being worn by all people. The invention further discloses a processing method for the warp knitted fabric containing the cotton.

Description

technical field [0001] The invention relates to a warp-knitted fabric, in particular to a cotton-containing warp-knitted fabric and a processing method thereof. Background technique [0002] Velvet fabric has fine texture, soft hand feeling, excellent wearing performance without pilling and color fading, excellent water absorption performance, three times that of cotton products, no irritation to the skin, no allergies, beautiful appearance, rich colors, existing High-grade velvet fabrics are generally made of warp-knitted fabrics. Warp-knitted velvet fabrics have excellent softness due to their fine silk and small flexural modulus. [0003] Coral velvet is a traditional velvet fabric produced by a low-gauge warp knitting machine. Due to its weaving raw materials, its structure is relatively loose and it is easy to shed hair. [0004] Sea-island velvet is a new type of velvet fabric. It is woven with a high-gauge warp knitting machine. The raw materials are sea-island silk,...

AI Technical Summary

Problems solved by technology

[0005] All natural fibers are short fibers, which need to be spun to make yarns. The surface hairiness of cotton yarns is long, and it is easy to fall off and form flying flowers and stains with dust, which can block needle holes and cause fabric defects. Smooth yarn often breaks and cannot weave normally

Conventional mercerized cotton yarns between 60S / 2 and 300S / 2 cannot be directly used for high-gauge warp knitting. The main reasons are as follows: 1. Mercerized yarns feel hard and lack the flexibility of polyester filaments. 2. There are many knots. Due to the stretching, dehydration and slow rewinding of mercerized cotton during mercerizing, a large number of broken ends will be formed, and the pinholes and hanging needles will be blocked during warp knitting. A large number of defects are formed on the cloth surface; 3. There is a lot of hairiness remaining, and flying flowers are formed during warp knitting, which blocks the pinholes; 4. The strength is low, and it cannot bear the tensile and draft strength during warp knitting and warping, and production cannot be realized. Conventional natural fiber high-count yarns are not suitable for weaving on high-gauge warp knitting equipment, so there are no natural fiber short-fiber high-gauge velvet fabrics at this stage
