Problems solved by technology

The dyeing method of this fabric is relatively conventional, mainly through the cooperation of disperse dyes, cationic dyes and acid dyes with the pH value and temperature of the dyeing solution, so as to achieve dyeing. There are many chemical materials in the process of this method, and they all need to be configured separately. The measurement requirements of the ingredients are relatively high, the realization is more complicated, and the color fastness has not been effectively improved

Embodiment 1

[0028] 1. 500kg nylon fabric is soaked in the first dye liquor that every liter contains 1.0gHT-33N and 0.05g SunacidOrange GSN (the total weight of the acid dye is 0.05% of the fabric weight), add 1M hydrochloric acid to adjust the pH to 4.0, Then treat at a temperature of 98°C for 40 minutes, and then cool down to below 60°C to discharge the liquid;

[0029] ② Soap the fabric treated in step ① at 40°C for 20 minutes and then drain;

[0030] ③Wash the fabric treated in step ② with water at room temperature first, and then perform acid color fixation at 60°C for 30 minutes after draining;

[0031] ④ Immerse the fabric treated in step ③ in hot water at 35°C containing polymers and wash it for 25 minutes. After draining, wash it with water at room temperature.

Embodiment 2

[0033] 1. Dip 500kg of nylon fabric into the first dye liquor containing 2.0gHT-33N and 3.0g Sunacid OrangeGSN (the total weight of the acid dyestuff is 0.5% of the fabric weight) per liter, add 2M hydrochloric acid agent to adjust the pH to 4.5 , and then treated at a temperature of 98°C for 30 minutes, and then cooled to below 60°C to discharge the liquid;

[0034] ② Soap the fabric treated in step ① at 40°C for 15 minutes before draining;

[0035] ③Wash the fabric treated in step ② with water at room temperature, drain the liquid, and then fix the color with acid at 65°C for 15 minutes;

[0036] ④ Immerse the fabric treated in step ③ in hot water at 35°C containing a special polymer and wash it for 25 minutes. After draining, wash it with water at room temperature.

Embodiment 3

[0038] 1. Dip 500kg of nylon fabric in the first dye liquor containing 1.8g HT-33N and 2.05g SunacidOrange GSN (the total weight of the acid dyestuff is 1.5% of the fabric weight) per liter, add 1.5M hydrochloric acid agent to adjust the pH 4.8, then treat at 100°C for 30 minutes, then cool down to below 60°C to drain;

[0039] ② Soap the fabric treated in step ① at 50°C for 18 minutes and then drain;

[0040] ③Wash the fabric treated in step ② with water at room temperature first, and then perform acid color fixation at 75°C for 20 minutes after draining;

[0041] ④Immerse the fabric treated in step ③ into hot water at 42°C containing a special polymer and wash it for 18 minutes. After draining, wash it with water at room temperature.

Abstract

The invention belongs to the technical field of textile dyeing, and particularly relates to a dyeing method of chinlon. According to the method, final cleaning is performed through high-molecular polymer, so that dyeing of chinlon is realized. The dyeing method is stable in technology, the flow is easy to control, and dyed fabric does not have defects, such as dyeing defects and color spots, and is high in bleeding resistance color fastness, high in washing color fastness and rubbing color fastness are high, and good in quality.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing, and in particular relates to a nylon dyeing method. Background technique [0002] Fibers are divided into chemical fibers and natural fibers. Chemical fibers are fibers with textile properties that are made from natural polymers or artificially synthesized polymers 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 (commonly known as nylon), scientifically known as polyamide fiber, is a kind of chemical fiber and is the first synthetic fiber in the world. Compared with polyester and acrylic fibers, nylon has the advantages of strong wear resistance, low...
