Abstract

The invention relates to a scouring agent formulation and a scouring and dyeing process, which are applied to multi-component fiber mixed fabrics or interwoven fabric in the process of weaving, printing and dyeing, manufacturing, scouring and dyeing in the same bath. The scouring agent comprises fatty alcohol ether, fatty alcohol ether carboxylate, alkyl polyglucoside, LAS, sulfonated succinic acid bisamide salts, SIP, PET, endoglucanase, laccase, protease, pectinase and lipase. The scouring and dyeing process is to add the scouring agent and dye into a scouring and dyeing bath at room temperature, use acetic acid to adjust the pH value of a liquid to be between 3.8 and 5.0, raise the temperature to be between 95 and 130 DEG C at the speed of 1 DEG C per minute, maintain at the temperature for 30 to 60 minutes, reduce the temperature to the room temperature, and exhaust the liquid. The invention has the advantages that the formulation is environment-friendly, saves water, vapor and the scouring and dyeing treatment time, and has low cost, and scoured textiles have good capillary effect, whiteness and dye uniformity.

Description

technical field [0001] The invention relates to a scouring agent formula and a scouring dyeing process for scouring dyeing in the same bath in textile printing and dyeing production, and is suitable for multi-component blended or interwoven fabrics of cellulose fibers, wool, polyester and other chemical fibers. technical background [0002] The production of multi-fiber blended or interwoven fabrics is becoming more and more popular. Through the blending or interweaving of various fibers in different proportions, the properties of various fibers can be complemented, and the fabric can obtain various new looks, new styles, and wearing properties. greatly improved. [0003] The traditional multi-component fabric scouring and dyeing adopts the two-bath method, and the scouring before dyeing is to obtain the required capillary effect and the effect of removing impurities and improving whiteness in a strong alkali bath at a high temperature of 100 °C. However, wool and spandex a...
