Problems solved by technology

However, this process is complicated, the efficiency is low, and the energy consumption is high.
At the same time, during scouring, alkaline solutions such as hydrosulfite and sodium carbonate are usually used for high-temperature treatment, which will cause greater damage to the fibers.
[0004] In addition, during the dyeing process of chemical fibers, in order to reduce environmental pollution, the use of natural dyes is currently being studied, but natural dyes usually need to be dyed at a lower temperature, and the dyeing effect of natural dyes is poor, and the dyed fabrics are solid. The chromaticity is low. In orde

Abstract

The invention discloses an efficient dyeing and finishing process for a chemical fiber fabric, which comprises the procedures of modification treatment, one-bath scouring dyeing, soaping, fixation, after finishing, drying, sizing, calendering and rolling. According to the invention, pretreatment is carried out by adopting ultrasonic wave; before the procedure of dyeing, the fabric is subjected to low-temperature plasma treatment, and then 2, 3-glycidyl trimethyl ammonium chloride is adopted for carrying out modification treatment on the fiber fabric, so that the degree of dyeing of the fabric is increased, and the difficulty of subsequent dyeing step is lowered; since one-bath scouring dyeing is adopted, the efficiency is increased, and the cost is lowered; in the dyeing procedure, use of a large quantity of alkaline substances and inorganic salt is avoided, nature dye is adopted, and colophony powder is added as a fixing agent, so that the color fixing effect is enhanced, environmental pollution is avoided, and the requirement of green environmental protection is met; furthermore, montmorillonoid is adopted to carry out flame retardant treatment on the fabric, so that the flame retardancy of the fabric is high. According to the invention, a yellowing-resisting reagent is used in the procedure of sizing, so that the final fabric cannot become yellow easily.

Description

technical field [0001] The invention relates to a high-efficiency dyeing and finishing process for chemical fiber 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-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] In the dyeing process of chemical fibers, in order to ensure the quality of dyeing, it is usually necessary to scouring, washing, dehydrating, drying, and setting the fabric before d...
