Problems solved by technology

[0003] Dyeing is an important process in chemical fiber treatment. There are two types of dyeing: high-temperature dyeing and low-temperature dyeing. Generally, the dyeing rate of high-temperature dyeing is relatively high, but there are still many defects in the high-temperature dyeing process. It is easy to damage the fiber wrinkle and reduce the elasticity, and the stability, reproducibility and uniformity of dyeing are not good

Abstract

The invention provides a high-temperature dyeing process for chemical fiber filaments, including pretreatment, presetting, dyeing, reductive soaping, color fixing, softening treatment, drying, setting, calendering, and winding. The present invention adds anti-staining salt S in the dyeing process, and adding anti-staining salt S can greatly improve the degree of damage to the dye by the potential aldehyde groups in the cellulose molecules in the chemical fiber filaments, so that the dyed product has a pure color and light, avoiding The color difference of dyeing is eliminated, the reproducibility and stability of dyeing are better, and high-temperature leveling agent is added to avoid the decrease of fuel heat resistance stability caused by the increase of temperature, which will lead to dye aggregation and affect the effect of level dyeing and penetration. Problems of color spots and stains may even occur, so that the dyeing effect is good; the chemical fiber filaments finally produced by the present invention are evenly dyed, stable, reproducible, elastic, soft, and have a firm dyeing degree.

Description

technical field [0001] The invention relates to the field of chemical fibers, in particular to a high-temperature dyeing process for chemical fiber filaments. Background technique [0002] Chemical fibers are fibers with textile properties that are made from natural polymer compounds or artificially synthesized polymer compounds through the processes of preparing spinning dope, spinning and post-treatment. It has the advantages of light resistance, wear resistance, easy washing and drying, no mildew and no moths. Widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, fishing nets, electrical insulation wires, medical sutures, tire cords and parachutes, etc. [0003] Dyeing is an important process in chemical fiber treatment. There are two types of dyeing: high-temperature dyeing and low-temperature dyeing. Generally, the dyeing rate of high-temperature dyeing is relatively high, but there are still many defects in the high-temperatu...
