阳离子改性涤纶毯的染整

Wet processing of easy cation-dyeable polyester blanket

采用阳离子改性涤纶(ECDP)为原料制作毯类织物,在常温常压下用阳离子染料等进行染整加工,其优化工艺为:采用阳离子红X-GRL、阳离子黄X-8GL、阳离子蓝X-BL和匀染剂,染液pH值4.5～5.0,轧余率100%,车速15 m/min;印花使用瓜尔胶为原糊,随后均进行长环悬挂汽蒸(100℃×25 min);后整理可采用5%柔软剂PS和2%蓬松剂PS。结果表明,加工后的阳离子改性涤纶毯织物具有较好的色泽鲜艳度、手感和染色牢度。

The blanket made from easy cation-dyeable （ECDP） polyester was dyed with cationic dyestuff in normal temperature and pressure conditions. Every process of dyes selection, dyeing and printing was analyzed and designed, and applied to largescale production. The optimal process was as follows： dyeing with cationic red X-GRL, cationic yellow X-8GL, cationic blue X- BL and levelling agent,pH value 4.5 - 5.0,pick up 100 %,printing with the same dyes and guar gum, running speed 15 m/ min,hanging steaming at 100 ℃for 25 minutes,and finishing with 5% softener PS and 2% bulking agent PS. The results showed that the treated blanket featured bright color, soft handle and good color fastness.
