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.
