Problems solved by technology

[0005] However, due to the low melting point of PLA fiber, high sensitivity to temperature, and easy degradation under strong alkali, the dyeing of PLA fiber is more difficult, and the dyeing of PLA fiber / pearl fiber blended fabric is even more difficult. Therefore, research It is one of the important problems to be solved for PLA fiber / pearl fiber blended fabrics to find out a method that is simple and can be dyed safely and effectively.

Abstract

The invention provides and discloses a dyeing and finishing process of a PLA fiber / pearl fiber blended fabric.The process includes the first step of singeing, the second step of desizing, the third step of souring and bleaching, the fourth step of whitening, the fifth step of presetting, the six step of mercerizing, the seventh step of primary dyeing, the eighth step of secondary dyeing, the ninth step of soaping, the tenth step of drying, the eleventh step of padding, the twelfth step of drying, the thirteenth step of baking, the fourteenth step of setting, the fifteenth step of calendering and the sixteenth step of rolling.By adding the whitening step before the presetting step, the whiteness and overall performance of the fabric are improved without damaging the fabric, and the stability and effectiveness of dyeing, padding, setting and calendering in the subsequent steps are guaranteed; two types of fiber are dyed according to the difference of dyes suitable for PLA fiber and pearl fiber, and the dyeing effect is further optimized.

Description

technical field [0001] The invention relates to a fabric dyeing and finishing process, in particular to a PLA fiber / pearl fiber blended fabric dyeing and finishing process. Background technique [0002] With the enhancement of human awareness of earth protection, energy depletion, safety awareness and clothing hygiene, as well as the large-scale industrial production of PLA resin and the continuous expansion of corn fiber applications, it has been recommended by many experts as "21st Century Environmental Protection". "Recycled material" is an ecological fiber with great development potential. PLA fiber is a synthetic fiber made from corn, wheat and other starches, which are fermented into lactic acid and then polymerized and spun. PLA fiber is made of lactic acid made from starch, which is a natural circulation type and biodegradable fiber. The fiber does not use chemical raw materials such as petroleum at all, and its waste can be decomposed into carbon dioxide and water...
