Problems solved by technology

[0004] In the dyeing process of nylon, in order to reduce environmental pollution, natural dyes are currently being studied for dyeing, but natural dyes usually need to be dyed at a lower temperature, and the dyeing effect of natural dyes is poor, and the dyed fabric has a low degree of color fixation. Low, in order to improve the color fixation, a large amount of soda ash and inorganic salts are usually added in the dyeing process, which brings great difficulties to the treatment of printing and dyeing wastewater with high salt content, such as direct discharge will destroy the ecological environment, resulting in soil salin

Abstract

The invention discloses a dyeing and finishing process for polyamide fabric. The provided process comprises pretreatment, pre-setting, modified processing, dyeing, soaping, dye fixation, post-finishing, drying, setting, calendering and rolling. Supersonic waves are employed for pretreatment, fabric is subjected to low temperature plasma processing before the dyeing step, then 2,3-epoxy propyl trimethyl ammonium chloride is employed for modification processing of the fabric, the dyeing degree of the fabric is raised, and difficulty of the subsequent dyeing step is lowered. During the dyeing step, a lot of alkaline substances and inorganic salt are not used, natural dyes are employed, colophony powder is added as a dye-fixing agent, the dye-fixing effect is enhanced, environment pollution is avoided, and green environmental protection requirements are met. Montmorillonite is employed for modification processing and flame retardation processing of the fabric, and thus the flame retardation of the fabric is high. Anti-yellowing reagents are used both in the pre-setting and setting steps, and thus the final fabric is not easy to turn yellow.

Description

technical field [0001] The invention relates to a dyeing and finishing process of nylon fabric. 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-treatment processes. Chemical fibers have the advantages of light resistance, wear resistance, easy washing and drying, no mildew, no moths, etc., and are widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, fishing nets, electrical insulation threads, medical sutures , tire cord and parachute etc. [0003] Nylon fiber, commonly known as nylon fiber, scientific name polyamide fiber, is a kind of chemical fiber, because of its excellent wear resistance, cold resistance, breathability and aging resistance. Therefo...
