One-bath dyeing of polyester/cotton blend with microencapsulated disperse/neutral fixation reactive dyes
摘要
Abstract
The microencapsulated disperse dyes and neutral fixation reactive dyes were applied in one-bath dyeing of polyester/cotton blend. The stain performance of neutral fixation reactive dyes on polyes⁃ter and microencapsulated disperse dyes on cotton, the effects of dyeing temperature, time, pH, dosage of so⁃dium chloride on dyeing behavior were analyzed. The color fastness of polyester/cotton blend fabrics dyed with neutral fixation reactive dyes and microencapsulated disperse dyes were tested. It was found that the neutral fixation reactive dyes stained less on polyester, and microencapsulated disperse dyes also stained less on cotton. The K/S value of dyed cotton fabric increased with the increasing of dosage of sodium chloride, but the K/S value of dyed polyester fabric decreased with the increasing of dosage of sodium chloride. The results showed that the optimal process was: addition neutral fixation reactive dyes and microencapsulated disperse dyes, NaCl 40 g/L or so, dyeing at 130 ℃ for 60 min under pH=7, the color fastnesses of polyester/cotton blend fibers could meet the demand of wearability.关键词
