Problems solved by technology

Among them, acid dyes represented by turquoise blue have more uneven dyeing problems when they are used, resulting in poor quality of finished fabrics and affecting market sales.
This phenomenon is because the dye is dyed too quickly after reaching the coloring condition, resulting in too much local coloring, resulting in uneven coloring as a whole

Embodiment 1

[0011] A kind of dyeing process of nylon fiber, comprises the steps:

[0012] 1) Add baking soda to the water, adjust the PH value to 9.5, add cloth, bath ratio 3:20, add dyes Tianlong Huang, Tianlong Blue and Tianlong Cuilan, mix water and dyes to form a dye solution, dye Tianlong Huang and cloth by weight The ratio is 0.05:1, the dye Tianlong blue and the cloth are 0.05:1 by weight percentage, the dye Tianlong emerald green and cloth is 0.5:1 by weight percentage, and a leveling agent is added to the dye liquor. And cloth is calculated as 0.05:1 by weight percentage;

[0013] 2) After heating the dye liquor to 70°C, add 0.4g / L acid release agent to the dye liquor, adjust the pH value of the dye liquor to 6, heat the dye liquor to 90°C, and keep it warm for 30 minutes.

Abstract

The invention discloses a polyamide fiber dyeing technology which comprises the following steps: 1) adding baking soda to water, adjusting the pH value to be 9.5, adding cloth with a bath ratio of 3:20, adding dye c, telon yellow, telon blue and telon emerald blue, mixing water and the dyes into a dye liquid with the weight ratio of the dye telon yellow to the cloth being 0.05:1, the weight ratio of the dye telon blue to the cloth being 0.05:1, the weight ratio of the dye telon emerald blue to the cloth being 0.5:1, a leveling agent added in the dye liquid and the weight ratio of the leveling agent to the cloth being 0.05:1; and 2) after the dye liquid is heated to 70 DEG C, adding a 0.4g / L acid release agent to the dye liquid, adjusting the dye liquid pH to 6, heating the dye liquid to 90-92 DEG C, and keeping warm for 30 minutes. The polyamide fiber dyeing technology is more even in coloring, and improves the quality of a finished product.

Description

technical field [0001] The invention relates to a dyeing process of nylon fiber. Background technique [0002] Nylon fabric can be dyed into various colors according to actual needs. At present, the demand for nylon fabrics with bright colors is increasing continuously in the market, and the demand for nylon fabrics with emerald blue color is even greater. In the process of dyeing fabrics, acid dyes of corresponding colors need to be used for whatever color needs to be dyed. Among them, acid dyes represented by turquoise blue have more problems of uneven dyeing when they are used, resulting in poor quality of finished fabrics and affecting market sales. This phenomenon is because the dye is colored too quickly after reaching the coloring condition, resulting in too much local coloring, resulting in uneven coloring as a whole. Contents of the invention [0003] The purpose of the present invention is to provide a dyeing process of nylon fiber, the coloring is more unifor...
