Problems solved by technology

[0003] The purpose of the present invention is to provide a preparation process for wear-resistant and anti-fading knitted fabrics. The composite yarn is prepared by blending wear-resistant fibers and cotton fibers, and then sizing is carried out through a weak acid sizing agent. Since the wear-resistant fiber preparation process is The monomer used is a monomer with a multi-conjugated structure. The polymer formed after polymerization has a high degree of conjugation, which can improve the wear resistance and toughness of the fabric, and solve the problem that is usually encountered in the preparation of the existing wear-resistant fabric. Can use cotton fiber, because the toughness and wear resistance of cotton fiber are strong, it can prevent clothes from wearing and tearing, but its wear resistance still cannot meet the requirements

Abstract

The invention discloses a preparation process of a wear-resistant and anti-fading knitted fabric. The specific preparation process is as follows: add cotton fibers to a sodium hydroxide solution with a concentration of 2%, heat up to 50-60°C and cook for 72 hours, and then wash until neutral After drying, it is blended with wear-resistant fiber filaments to obtain composite yarn; detergent, dispersant, dye and water are added to the dye vat at the same time, and then the composite yarn is added to the dye vat for dip dyeing, then washed in hot water, and The washed composite yarn is dried and knitted to form a knitted fabric; the knitted fabric is added to a sizing agent for sizing treatment to obtain a wear-resistant and anti-fading knitted fabric. In the present invention, composite yarns are prepared by blending wear-resistant fibers and cotton fibers, and then subjected to sizing treatment with a weakly acidic sizing agent. Since the monomers used in the preparation of wear-resistant fibers are monomers with multi-conjugated structures, after polymerization The formed polymer has a higher degree of conjugation, which in turn can improve the wear resistance and toughness of the fabric.

Description

technical field [0001] The invention belongs to the field of fabric preparation and relates to a preparation process of a wear-resistant and anti-fading knitted fabric. Background technique [0002] In workshop operations and construction site operations, since clothing often rubs against hard and rough objects, and high-intensity work processes are prone to sweating, the wear resistance of workers' uniforms determines the wearing life and comfort of clothing. The existing wear-resistant Cotton fiber is usually used in the fabric preparation process. Due to the strong toughness and wear resistance of cotton fiber, it can prevent clothing from wearing out. However, its wear resistance still cannot meet the requirements. At the same time, the existing fabrics are usually made of polyester. Acrylic acid is used as a sizing agent for sizing treatment, so that the surface of the fabric is covered with a layer of sizing agent. The protective effect of the sizing agent is used to e...
