Problems solved by technology

At the same time, because it is a composite fiber, dyeing migration between cotton and wool blended fibers is easy to occur during the dyeing process, it is difficult to control the level dyeing property, and the dyeing quality is poor
[0005] Although low-temperature dyeing has lower requirements on equipment and lower energy consumption, the dyeing effect is poor, and the color fixation of the dyed fabric is low. In order to improve the color fixation, a large amount of soda ash and Inorganic salt, which brings great

Abstract

The invention discloses a low-temperature dyeing and finishing technology of cottonette. The technology comprises the following steps: pretreatment; preshaping; modification treatment; dyeing; mordant removing; soaping; color fixing; post-treatment; drying; shaping; calendaring; rolling. According to the technology, pretreatment is carried out through the adoption of helicase and alpha-amylase, and modification treatment is carried out before dyeing, so that the property of the cottonette is fundamentally modified, and the dye-uptake of the fabric is increased; during the dyeing procedure, large quantities of alkaline substances and inorganic salt are not used, and a levelling agent, a low-temperature dyeing accelerant, a migration inhibitor and a dispersing agent are added, so that the dye uniformity is improved; during the whole dyeing process, the temperature is lower than 80 DEG C, and the dyeing process belongs to low-temperature dyeing, so that energy consumption is reduced; self-cleaning treatment is added in post-treatment, so that the self-cleaning capacity, wrinkle resistance and water washable firmness of the fabric are improved; post-treatment is carried out through the adoption of silk fibroin and sericin, so that the pilling resistance and antistatic property of the cottonette are improved; the whole technology is environment-friendly and free of pollution.

Description

technical field [0001] The invention relates to a low-temperature dyeing and finishing process of cotton and wool blended fabrics. Background technique [0002] Fiber is divided into chemical fiber and natural fiber. Natural fiber refers to the fiber that exists and grows in nature and has textile value. Chemical fiber is made of natural polymer compound or artificially synthesized polymer compound. Fibers with textile properties produced by silk and post-processing processes. Chemical fibers have the advantages of light resistance, wear resistance, easy washing and drying, no mildew, and no moths. They are widely used in the manufacture of clothing fabrics, filter cloths, and conveyor belts. , hoses, ropes, fishing nets, electrical insulation wires, medical sutures, tire cords and parachutes etc. [0003] Cotton wool blended fabric is a kind of composite fiber fabric, including cotton fiber and wool fiber, and has the characteristics of cotton fiber and wool fiber at the s...
