Dyeing and finishing process of recycled high-density nylon cool fabric

Abstract

The invention discloses a dyeing and finishing process for recycled high-density nylon cool fabrics. The dyeing and finishing process includes a pretreatment process, a dyeing process and a setting process carried out in sequence; the pretreatment process includes a cold pad-batch process and flat-width desizing and water washing process; the dyeing process includes a coloring stage and a moisture-wicking finishing stage; the dyeing agent used in the coloring stage includes dyeing auxiliaries and dyes; after the coloring stage is completed, the liquid is drained, and then moisture-wicking finishing agent is added for moisture-wicking finishing ; Dyeing auxiliaries include acid leveling agent, nylon fiber dyeing accelerator, pH slip agent, anti-ultraviolet Leo Mountain C and anti-ultraviolet DEL; moisture-wicking finishing agents include moisture-wicking agent and slip agent VS. In the present invention, by formulating a suitable pretreatment process, dyeing process and setting process, the fabric has the functions of air permeability, moisture permeability, coolness and ultraviolet resistance, and is soft, ultra-thin, and bright in color under the premise of ensuring the dyeing quality and fabric feel. , fashion light sense and other new features.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing and finishing process for 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...

AI Technical Summary

Problems solved by technology

The technical problems in the dyeing and finishing process are: (1) Regenerated nylon fiber has a small fiber radius and irregular shape structure, low fiber linear density, large specific surface area, and fast adsorption of acid dyes, resulting in nylon Fabrics are prone to problems such as colored flowers and uneven dyeing during dyeing; (2) The fiber-to-fiber arrangement density of the fabric is high, and the specific surface area of ​​the fibers is large, and the amount of oil on the monofilament is large, so high polymerization degree is required for warping and weaving. The high-concentration and medium-viscosity sizing size, oil agent, wax, etc. make it difficult to remove the size and oil agent in the micro-air chamber between high-density fibers during desizing
