Dyeing process of cyclically regenerated high-density polyamide cool fabric

Abstract

The invention discloses a dyeing process of a cyclically regenerated high-density polyamide cool fabric. The dyeing process comprises a coloring stage and a moisture-absorbing and sweat-releasing finishing stage; a dyeing agent adopted in the coloring stage comprises a dyeing auxiliary agent and a dye; after the coloring stage is completed, liquid is discharged, and then a moisture-absorbing and sweat-releasing finishing agent is added for moisture-absorbing and sweat-releasing finishing; the dyeing auxiliary agent comprises an acidic leveling agent, a polyamide fiber dyeing accelerating agent, a pH slipping agent, anti-ultraviolet Rayosan C and anti-ultraviolet DEL; and the moisture-absorbing and sweat-releasing finishing agent comprises a moisture-absorbing and sweat-releasing agent and a slipping agent VS. According to the characteristics of the cyclically regenerated high-density polyamide fabric, the color brightness, the color fastness and the hand feeling of the dyed fabric are improved by adopting the proper dyeing auxiliary agent, dye and moisture-absorbing and sweat-releasing finishing agent and designing a reasonable dyeing process curve, and the fabric is endowed with the better anti-ultraviolet effect and moisture-absorbing and sweat-releasing effect.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing process of recycled high-density nylon cool fabric. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for the function of clothing fabrics. In addition to normal wearing requirements, they also require comfortable wearing, skin tenderness, and no skinny feeling when in contact with the skin. Therefore, in recent years, textile fabrics have shown a development trend of light and thin structure, fashionable style and functional use. In order to resist the hot summer, a kind of "cool skin clothing" as thin as cicada's wings and as light as catkins also came into being. "Cool skin clothing" is made of regenerated high-density nylon fabric (with anti-ultraviolet function and the official mass per square meter of single-layer fabric is not more than 42g / m 2 Textile fab...

AI Technical Summary

Problems solved by technology

For the dyeing process, regenerated nylon fiber has a small fiber radius and irregular shape structure, and the fiber linear density is low, the specific surface area is large, and the adsorption speed of acid dyes is fast, which makes nylon fabrics prone to discoloration during dyeing. Flowers, uneven dyeing and other problems; therefore, how to improve the dyeing process of high-density recycled nylon fabrics plays an important role in the quality of the product
