Embodiment 1

[0026] A dyeing method for improving the dyeing performance of high-elastic nylon 6 fibers. The specific steps are: before the high-elastic nylon 6 fibers are dyed with acid dyes, first select 4g / L glacial acetic acid and 3g / L acid penetrant, and use a volume ratio of 3: 1 Mix evenly, adjust the pH value to 2 to prepare the pretreatment solution, immerse the fiber in the pretreatment solution, raise the temperature of the pretreatment solution to 100°C, keep it warm for 30 minutes, cool the pretreatment solution to room temperature, take out the fiber, wash and dry it with warm water Dry; the pretreated fiber is immersed in the acid dye solution in the autoclave according to the liquor ratio of 10:1, and the autoclave is heated to 80°C, while the pressure in the autoclave is increased to 150kPa, and the dye solution is kept warm for 40min , then cool the dyeing solution to room temperature, open the autoclave to take out the fiber, and then carry out water washing, soaping, wat...

Embodiment 2

[0028] Before the high-elastic nylon 6 fiber is dyed with acid dyes, first select 4g / L glacial acetic acid and 4g / L acid penetrant, mix them uniformly at a volume ratio of 5:1, and adjust the pH value to 2 to prepare a pretreatment solution. Immerse in the pretreatment solution, raise the temperature of the pretreatment solution to 100°C, keep it warm for 30 minutes, cool the pretreatment solution to room temperature, take out the fiber, wash it with warm water, and dry it; the pretreated fiber is immersed in an autoclave at a bath ratio of 15:1 In the acid dye solution in the acid dyeing solution, the autoclave is heated to 80°C, and the pressure in the autoclave is raised to 150kPa at the same time, and the dye solution is kept warm for 50 minutes, and then the temperature of the dye solution is cooled to room temperature, and the autoclave is opened to take out the fiber and then carry out sequentially It is washed, soaped, washed, and dried to obtain dyed high-elastic nylon...

Embodiment 3

[0030] Before the high-elastic nylon 6 fiber is dyed with acid dyes, first select 5g / L glacial acetic acid and 4g / L acid penetrant, and mix them uniformly at a volume ratio of 5:1, and adjust the pH value to 2 to prepare a pretreatment solution. Immerse in the pretreatment solution, raise the temperature of the pretreatment solution to 100°C, keep it warm for 30 minutes, cool the pretreatment solution to room temperature, take out the fiber, wash it with warm water, and dry it; the pretreated fiber is immersed in an autoclave at a bath ratio of 20:1 In the acid dye solution in the acid dyeing solution, the autoclave is heated to 80°C, and the pressure in the autoclave is increased to 170kPa at the same time, and the dye solution is kept warm for 50 minutes, and then the temperature of the dye solution is cooled to room temperature, and the autoclave is opened to take out the fiber and then carry out sequential treatment. It is washed, soaped, washed, and dried to obtain dyed hi...

Abstract

The invention discloses a dyeing method capable of improving the dyeing performance of high-elastic nylon 6 fibers. The method comprises the steps of dyeing pretreatment, a dyeing process and a color fixing process. According to the dyeing method, the dyeing performance of the high-elastic nylon 6 fibers can be effectively improved, the dyeing rate, the fixation rate, the K / S value and the level dyeing performance of the fibers are remarkably improved, and the washing color fastness, the rubbing color fastness and the light color fastness of fabric are improved. The process is simple and efficient, the usage amount of dye can be remarkably reduced, the method is environmentally friendly, the adopted reagent is efficient in dyeing, bright in color and not prone to fading, and the efficient and lasting dyeing effect can be achieved. On the basis that the dyeing performance of the high-elastic nylon 6 fibers is enhanced, the simplicity, high efficiency and environmental friendliness of the dyeing process are further improved, and wide application of the high-elastic nylon 6 fibers and fabric can be promoted.

Description

technical field [0001] The invention belongs to the field of dyeing technology of high-elastic nylon 6 fibers, and in particular relates to a dyeing method for enhancing the dyeing performance of high-elastic nylon 6 fibers. Background technique [0002] With the improvement of people's requirements for clothing comfort, the application of elastic fibers in the textile field has become more and more extensive, and its application fields have changed from traditional socks, underwear, knitted sweaters, etc. development in other fields. In addition, it also has broad application prospects in the fields of automobile decoration and medical hygiene. [0003] Elastic fiber is a fiber material with a certain fineness that has certain elastic elongation and elastic recovery properties, and can be obtained from a high molecular polymer with a special structure or modified through a certain spinning process. The definition of an elastomer by the American Society for Experimental Ma...
