Abstract

The invention discloses an environmental-friendly dyeing and finishing process of a real silk fabric. The environmental-friendly dyeing and finishing process of the real silk fabric comprises pretreatment, presetting, cryogenic freezing treatment, dyeing, mordant removal, soaping, color fixing, post-finishing, drying, setting, calendering and winding. By performing pretreatment with helicase and alpha-amylase and by adopting cryogenic freezing treatment before dyeing, the performance of the real silk fabric is fundamentally modified and the dye uptake rate of the fabric is improved; a great amount of alkali substances and inorganic salt are not used in the dyeing process and leveling agent and dispersing agent are added, the dyeing uniformity is improved, the environmental pollution is avoided by using natural dyes and the requirements on the environmental protection are satisfied; since self-cleaning treatment is added during post-treatment, the self-cleaning ability, the wrinkling resistance and the water washing fastness of the fabric are improved; the entire process is environmental-friendly and pollution-free.

Description

technical field

[0001] The invention relates to an environment-friendly dyeing and finishing process for real silk fabrics. Background technique

[0002] Fiber is divided into chemical fiber and natural fiber. Chemical fiber has the advantages of light resistance, wear resistance, easy washing and drying, no mildew, and no moth. It is widely used in the manufacture of clothing fabrics, filter cloth, conveyor belts, hoses, ropes, Fishing nets, electrical insulating wires, medical sutures, tire cords and parachutes, etc. Natural fibers refer to fibers that exist and grow in nature and have textile value. Chemical fibers use natural polymer compounds or artificially synthesized polymer compounds as raw materials. , through the preparation of spinning dope, spinning and post-processing and other processes made of fibers with textile properties.

[0003] Silk is a kind of natural fiber, to be precise, a kind of natural protein fiber. Because of its good moisture absorption, brea...
