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

[0016] Example 1, add pure salty Na to water at normal temperature (20°C-25°C) 2 CO 3 , make the pH value of the water to 8.8, then add the cloth to be dyed in the water, the specific gravity of the cloth and water is 1 kg: 10 liters, that is, add a cloth with a weight of 1 kg in 10 liters of water. Then add three kinds of dyes, Tianlong Huang, Tianlong Blue and Tianlong Cuilan, in the water, wherein the ratio of dye Tianlong Huang to cloth is 0.045:1 by weight, the dye Tianlong blue to cloth is 0.015:1 by weight, and the dye Tianlong The ratio of green orchid and cloth is 0.24:1 by weight percentage. That is to say, if the added cloth is 1 kilogram, the weight of the added dyes Tianlonghuang is 0.045 kilograms, that of Tianlong blue is 0.015 kilograms, and that of Tianlong emerald blue is 0.24 kilograms. A leveling agent is also added to the dyeing solution, and the ratio of the leveling agent and the cloth is 0.01:1 by weight, that is, 0.01 kg of leveling agent is added to...

Embodiment 2

[0017] Example 2, add pure salty Na to water at normal temperature (20°C-25°C) 2 CO 3 , make the pH value of the water to 9.0, then add the cloth to be dyed in the water, the specific gravity of the cloth and water is 1 kg: 10 liters, that is, add 1 kg of cloth to 10 liters of water. Then add three kinds of dyes, Tianlong Huang, Tianlong Blue and Tianlong Cuilan, in the water, wherein the ratio of dye Tianlong Huang to cloth is 0.045:1 by weight, the dye Tianlong blue to cloth is 0.015:1 by weight, and the dye Tianlong The ratio of green orchid and cloth is 0.24:1 by weight percentage. That is to say, if the added cloth is 1 kilogram, the weight of the added dyes Tianlonghuang is 0.045 kilograms, that of Tianlong blue is 0.015 kilograms, and that of Tianlong emerald blue is 0.24 kilograms. A leveling agent is also added to the dyeing solution, and the ratio of the leveling agent and the cloth is 0.01:1 by weight, that is, 0.01 kg of leveling agent is added to 1 kg of cloth. ...

Embodiment 3

[0018] Example 3, add pure salty Na to water at normal temperature (20°C-25°C) 2 CO 3 , make the pH value of the water to 9.2, then add the cloth to be dyed in the water, the specific gravity of the cloth and water is 1 kg: 10 liters, that is, add 1 kg of cloth in 10 liters of water. Then add three kinds of dyes, Tianlong Huang, Tianlong Blue and Tianlong Cuilan, in the water, wherein the ratio of dye Tianlong Huang to cloth is 0.045:1 by weight, the dye Tianlong blue to cloth is 0.015:1 by weight, and the dye Tianlong The ratio of green orchid and cloth is 0.24:1 by weight percentage. That is to say, if the added cloth is 1 kilogram, the weight of the added dyes Tianlonghuang is 0.045 kilograms, that of Tianlong blue is 0.015 kilograms, and that of Tianlong emerald blue is 0.24 kilograms. A leveling agent is also added to the dyeing solution, and the ratio of the leveling agent and the cloth is 0.01:1 by weight, that is, 0.01 kg of leveling agent is added to 1 kg of cloth. ...

Abstract

The invention discloses a dyeing technology of polyamide fibers, comprising the following steps: (1) adding soda ash Na2CO3 in water until the pH value of the water is 8.8-9.2, adding the cloth in the water with the ratio of the cloth to the water being 1lg:10L, adding dyes telon yellow, telon blue, telon emerald blue to the water and mixing to form a dye liquor, and adding levelling agent to the dye liquor, wherein weight ratio of the telon yellow to the cloth is 0.045:1, the weight ratio of the telon blue to the cloth is 0.015:1, the weight ratio of the telon emerald blue is 0.24:1, and the weight ratio of the levelling agent to the cloth is 0.04:1; and (2) heating up the dye liquor to 70 DEG C, then adding acid-releasing agent to the dye liquor, wherein the ratio of the acid-releasing agent to the water is 0.4g:1L, and the acid-releasing agent is added to the dye liquor at a speed of 0.0067-0.008g / min to reduce the pH value of the dye liquor to 6.5. According to the invention, the technology dyes the cloth uniformly, and greatly reduces the cost of repair or rework.

Description

technical field [0001] The invention relates to a dyeing process, in particular to a nylon fiber dyeing process. Background technique [0002] In recent years, with the growing maturity of the nylon elastic fiber market, nylon fabric products have been used more and more. Due to the needs of customers, nylon fabrics will 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 colo...
