Once-wash multiple-active perssad dye mixed base dyeing method for natural silk blend fabric

Abstract

The invention discloses a shower multi-activity dyeing method of silk floss blending fabrics. According to the structure of silk molecule, it uses the cross-linking effect of multi-activity base dye to multi-reaction between silk fiber structure, it decreases the raw fiber rate, at the same time, it uses the caustic soda and soda ash as soda agent, the silk fiber and cotton fiber will properly swell, it is beneficial for dye to permeate into fiber, enhances the homogeneity, reappearing and color quantity of dyeing, the invention can dye silk floss blending fabrics on time.

Description

technical field [0001] The present invention relates to a kind of dyeing method of blended fabric, specifically relate to the dyeing method of TENCEL (TENCEL) and cotton blended fabric, more specifically relate to TENCEL (TENCEL) and cotton blended fabric one-bath multi-reactive group dye Mixed base staining method. Background technique [0002] Since Tencel itself has a high degree of orientation and high crystallinity, and has high metafibrillation and transverse swelling in the wet process, so Tencel (TENCEL) and cotton blended fabrics are prone to metafibrillation during the dyeing process. And problems such as poor fastness and not deep dyeing, especially black, it is difficult to achieve the ideal blackness. With the traditional process, energy is wasted (working hours, water, electricity, steam, dyes), not only the dark fabrics cannot meet the color requirements, but also the excessive use of dyes affects the fastness and increases the amount of sewage discharge, and...

Problems solved by technology

[0002] Since Tencel itself has a high degree of orientation and high crystallinity, and has high metafibrillation and transverse swelling in the wet process, so Tencel (TENCEL) and cotton blended fabrics are prone to metafibrillation during the dyeing process. And problems such as poor fastness and not deep dyeing, especially black, it is difficult to achieve the ideal blackness

With the traditional process, energy is wasted (working hours, water, electricity, steam, dyes), not only the dark fabrics cannot meet the color requirements, but also the excessive use of dyes affects the fastness and increases the amount of sewage discharge, and also increases the production cycle. limited production
