Abstract

The invention relates to the technical field of the chemical fiber dyeing process and provides a dyeing process of a chemical fiber with the efficient anti-decoloring performance. According to the dyeing process, the chemical fiber is pretreated by using a degreaser before dyeing and cleaned through a non-ionic cleaning agent 6501 after pretreatment so that greasy dirt and electrostatic ions attached to the chemical fiber can be removed; since the surface of the chemical fiber has negative charge, sodium sulfate can be added to enhance the ion strength of a solution and accelerate a staining reaction in the dyeing process, and then a dyeing agent can be more firmly adsorbed to the surface of the chemical fiber. According to the dyeing process, the pH value of the dyeing solution is adjusted to 8 before color fixing, active groups in reactive dye molecules can react with hydroxyl and amidogen in the chemical fiber to reach the covalence so that the reactive dye molecules can be tightlyadsorbed to the surface chemical fiber through covalent bonds, the chemical fiber can be prevented from decoloring to some extent, and the color fixing effect is good.

Description

technical field [0001] The invention relates to the technical field of chemical fiber dyeing process, in particular to a chemical fiber dyeing process with high-efficiency anti-bleaching performance. 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. Fiber length, thickness, whiteness, gloss and other properties can be adjusted during the production process. And they have the advantages of light resistance, wear resistance, easy washing and drying, no mildew, no moths and so on. 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. Generally, polymer compounds can be made into solutions or melts, extruded from the pores of the spinneret, and th...
