Colored spun silk dyeing device and colored spun silk dyeing process

Abstract

The invention relates to the technical field of colored spun silk dyeing, in particular to a colored spun silk dyeing device and a colored spun silk dyeing process. According to the method, spun silk fibers are carded and opened, then are modified by using a modifier, are dyed by using a reactive dye and a leveling agent under a weakly alkaline condition, and are dehydrated to remove redundant dyes; then soaping of the spun silk fibers is conducted under certain temperature and time conditions to remove surface dyeing and fix the color, a softening agent and a smoothing agent are added under certain moisture content of the spun silk fibers to increase the softness and smoothness of the spun silk fibers, and tentering and setting are conducted at high temperature. Through the method, the dip dyeing effect of the dye on the spun silk fibers is effectively enhanced; and after dip dyeing of the spun silk fibers is completed, centrifugal dewatering of the spun silk fibers can be immediately achieved in a dye cavity, redundant dye for dip dyeing of the spun silk fibers is removed, waste of the dye is avoided, the dyeing effect of the color spun silk is improved through aftertreatment of the spun silk fibers, and the quality of the color spun silk is guaranteed.

Description

technical field [0001] The invention relates to the technical field of color spinning spun silk dyeing, in particular to a dyeing device and process for color spinning spun silk. Background technique [0002] In the production of colored spinning spun silk, that is, in the production of spun silk fibers, appropriate coloring agents are added during polymerization or spinning, and the coloring agents are evenly dispersed in the spun silk fibers after spinning. The advantage is that coloring and spinning can be carried out continuously. , Uniform coloring, good color fastness, high dyeing rate, short production cycle, low cost and less pollution. [0003] Most of the existing loose fiber dyeing machines have a single structure and function, which can easily cause the spun silk fibers to not be well uniformly colored and scattered, and the dyeing effect is average, and it is easy to cause excess dye liquor to be lost during the transfer and dehydration process of the spun silk ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing loose fiber dyeing machines have a single structure and function, which can easily cause the spun silk fibers to not be well uniformly colored and scattered, and the dyeing effect is average, and it is easy to cause excess dye liquor to be lost during the transfer and dehydration process of the spun silk fibers after dyeing. Waste, and in the existing color spinning silk dyeing process, the strength of the silk fiber itself is greatly affected during the dyeing process
