Problems solved by technology

[0005] Although blended fibers have many advantages, there are still some problems in the notice. For example, if the performance difference of its components is relatively large, then in the dyeing process, the requirements for its technology are relatively high, and continuous research and development must be carried out. The dyeing process of all its components
[0006] At present, there are often some problems in the dyeing process of blended fibers containing nylon: pre-treatment is easy to damage the fiber; creases are prone to occur in pre-treatment, dyeing and other processes; dyeing rate is low, dyeing is not fast; color flowers will appear; Poor staining stability

Abstract

The invention provides a dyeing process of a chinlon-containing blended fiber. The dyeing process comprises the following steps of preforming, pretreatment, drying, dyeing, drying, finished product forming and winding. According to the dyeing process, the preforming is carried out before the pretreatment, so that the phenomenon that crumples appear on the chinlon-containing blended fiber; a high-temperature leveling agent is added in the dyeing procedure, so that the problem that level dyeing effect and penetration dyeing effect are influenced and even color dots and color patches occur caused by the gathering of dyes because the heat stability resistance of fuel is lowered due to temperature increase is prevented, and good dyeing effect is achieved; the final dye-uptake rate of the chinlon-containing blended fiber can achieve 75%, the soaping color fastness of the dyed fiber achieves 5 level, and good water shrinkage and washing fastness and low strength loss of the dyed fiber are achieved.

Description

technical field [0001] The invention relates to the field of chemical fibers, in particular to a dyeing process of blended fibers containing nylon. 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] Nylon is the earliest synthetic fiber variety in the world. Its biggest feature is its high strength and good wear resistance. Its strength and wear resistance rank first among all fibers. [0004] Blended fibers, also known as multi-component fibers, refer to chemical fibers spun...
