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 Immerse 500kg of cotton fabric in the first dyeing solution containing 1.0gHT-33N and 0.05g SunacidOrange GSN per liter (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 98°C for 40 minutes, and then cool to below 60°C to drain;

[0029] ②The fabric treated in step ① is soaped at 40℃ for 20 minutes and then drained;

[0030] ③The fabric treated in step ② is washed at room temperature first, and after draining, it is acid-fixed at 60°C for 30 minutes;

[0031] ④The fabric treated in step ③ is immersed in 35°C hot water containing high molecular polymer and washed for 25 minutes. After draining, it is washed at room temperature.

Embodiment 2

[0033] ①Soak 500kg of cotton fabric in the first dyeing solution containing 2.0g HT-33N and 3.0g Sunacid Orange GSN per liter (the total weight of the acid dye is 0.5% of the fabric weight), and add 2M hydrochloric acid to adjust the pH to 4.5 , Then treat it at 98℃ for 30min, then cool to below 60℃ to drain;

[0034] ②The fabric treated in step ① is soaped at 40°C for 15 minutes and drained;

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 specifically relates to a dyeing method of nylon. Background technique [0002] Fibers are divided into chemical fibers and natural fibers. Among them, chemical fibers are fibers with textile properties that are made from natural polymer compounds or synthetic polymer compounds as raw materials, through the preparation of spinning dope, spinning, and post-processing. It has the advantages of light resistance, abrasion resistance, easy to wash and dry, no mildew, no insects, etc. It is widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, fishing nets, electrical insulation wires, medical sutures, tire cord fabrics and parachutes, etc. [0003] Nylon (commonly known as nylon), whose scientific name is polyamide fiber, is one of the chemical fibers and is the first synthetic fiber in the world. Compared with polyester and acrylic, nylon has the advan...
