Abstract

The invention relates to an ultrasonic dyeing process of a polylactic acid/richel/bamboo fiber blended fabric. By virtue of ultrasonic wave, disperse dyes maintain stable particle diameter in dyeing bath; an association body between the dyes is crushed; the dispersion of the dyes is improved; the ultrasonic wave has small influence on the fabric; the breakage strength of the fabric is slightly alleviated under the action of the ultrasonic wave; the fabric fiber surface is not obviously etched. The disperse dyes suitable for the process are relatively wide in types; the dyeing percentage and the K/S value of the disperse dyes are obviously improved; compared with the conventional dyeing process, the K/S value is averagely increased by 16.03; a relatively obvious acceleration effect is achieved for the dyeing of dark colors.

Description

technical field [0001] The invention relates to the field of textiles, in particular to an ultrasonic dyeing process of polylactic acid / Liesel / bamboo fiber blended fabric. Background technique [0002] Ultrasonic dyeing is an environmentally friendly dyeing method. Since the 1940s and 1950s, people have carried out sonochemical research in many fiber dyeing processes. There are mainly ultrasonic dyeing of direct dyes, reactive dyes and vat dyes of cotton fibers, ultrasonic dyeing of acid dyes and direct dyes of wool fibers. [0003] Wang Haiying and others studied the effect of ultrasonic pretreatment on the dyeing performance of PET fabrics. By discussing the influence of ultrasonic frequency, pretreatment time, pretreatment temperature and alkali concentration on the color depth of the treated fabric, the influence on the dyeing performance of PET was found. And optimize the ultrasonic treatment conditions. The experimental results show that after the PET fabric is ultra...
