涤氨针织面料常压染色工艺探讨

Study on the Dyeing Process of Polyester/Spandex Knitted Fabric at Atmospheric Pressure

为降低涤氨针织物的染色温度,采用肉桂酸作为载体进行常压染色。探讨了载体种类、载体用量、pH值、染色时间、染色温度等因素对涤氨针织物染色性能的影响。结果表明在分散红玉DRD用量3%(owf)时的最佳工艺为:肉桂酸载体用量8%(owf),100℃保温染色45min。载体法染色与高温高压法染色相比较,染色织物的K/S值略小,但差别不大。摩擦牢度、皂洗牢度、升华牢度与高温高压法染色织物相同。

In order to reduce the dyeing temperature of polyester/spandex knitted fabric, cinnamic acid was used as a dyeing carri- er on atmospheric pressure dyeing of polyester/spandex knitted fabric with disperse dyes. The influences of the type and dosage of the carrier, pH value, dyeing temperature and time on the dyeing performance of polyester/spandex fabric were investigated. The results showed that the optimal dyeing process as follows： disperse dye 3% （ owf ）, cinnamic acid 8% （ owf ）, dyeing at 100℃ for 45 min. There was little differences on the K/S value between the carrier dyeing and high temperature ＆ pressure process dyeing. There was no difference on rubbing fastness, washing fastness and sublimation fastness between the carrier dyeing and high temperature pressure process dyeing.
