Title: Preparation and pad dyeing performance of ultrafine indigo dye dispersion
Abstract: The preparation process of ultrafine indigo dye dispersion and its pad dyeing performance on cotton fabric are studied.The effect of structure and dosage of dispersant,content of dyes in suspension,as well as dispersion time on indigo size are investigated.As a result,the optimal preparation process of ultrafine indigo dye dispersion is dispersant FPE 30%(on mass of dye),dye 5%,treating 70 min with ultrasonic power 800 W.The optimized pad dyeing process is dye 1%,pick up 70%,padding 3 times,hydrosulfite 3.4%.Compared with conventional indigo dye,the color fastness to abrasion and washing of dyed fabrics with ultrafine indigo dye are improved.
