Problems solved by technology

[0003] Dyeing is an important process in chemical fiber treatment. Dyeing usually adopts high-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. For example, if the temperature is too high, it is easy to make the fiber Damaged creases, reduced elasticity, and poor dyeing stability, reproducibility, and uniformity
At the same time, the energy consumption of high temperature dyeing is relatively high

Abstract

The invention provides a low-temperature dyeing process of a fiber fabric. The low-temperature dyeing process comprises the processes of pretreatment, pre-sizing, dyeing, reduction clearing, fixing, softening treatment, drying, sizing, calendaring and rolling. In the dyeing process, the highest temperature does not exceed 100 DEG C, mild dyeing is carried out by using a gradual warming method and pH value regulation is carried out through a buffer solution, so that a proper acid environment required during the dyeing is satisfied and the dyeing effect is excellent; during the dyeing, a leveling agent is added to ensure that the dyeing is uniform; anhydrous sodium sulphate is added to postpone the dyeing process of the pigment and the temperature rises slowly at the same time, so that the uniform dyeing is ensured; a smoothing agent is added to prevent the scratching and local fibrillation; a penetrant and a diffusant are added to ensure that the penetration and the diffusion of the dyeing are relatively good; by means of the strict control in the aspects of temperature, acid, auxiliaries, time and the like, the low-temperature dyeing process of the fiber fabric has the advantages that the dyeing firmness is high, the dyeing is uniform, the dyeing stability is good and the effect is excellent at low temperature.

Description

technical field [0001] The invention relates to the field of chemical fibers, in particular to a low-temperature dyeing process for fiber fabrics. 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. Dyeing usually adopts high-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. For example, if the temperatu...
