摘要
采用架桥剂PW对棉织物进行预处理,再采用分散彩蓝B进行低温染色。探讨架桥剂PW质量浓度、p H值、焙烘温度和染色温度对染色K/S值的影响。优化的预处理工艺为:架桥剂PW 200 g/L,p H值4,150℃焙烘40 s;处理后较佳的染色温度为90℃。染色棉织物匀染性和色牢度较好,染色温度低,节能环保。
Pretreatment of cotton fabric with bridging agent PW and low temperature dyeing of cotton fabric with Disperse Blue B are carried out. The effects of bridging agent PW concentration, pH value, curing and dyeing temperatures on K/S value are discussed. The optimum finishing process is： bridging agent PW 200 g/L, pH value 4, curing at 150 ℃ for 40 s, and then dyeing at 90 ℃. The results show that the process has advantages of low dyeing temperature, good levelness and fastness of dyed cotton fabric, energy conservation and environmental protection.
