分散艳蓝BR在涤氨针织物上染色工艺的研究

Study of Dyeing Process of Polyester and Spandex Interweaving Fabric With Disperse Brilliant Blue BR

针对分散艳蓝BR在涤氨交织针织物染色时，染色一次成功率不高的问题，讨论了浴比、染浴pH值和匀染剂种类及用量等因素对分散艳蓝BR在涤氨交织针织物上染色性能的影响。结果表明：涤氨交织针织物染色时，加入匀染剂后织物朋值有所降低，但随着匀染剂用量的加大，氨纶丝上的颜色却随之加深；多功能匀染剂LDM性能较好，优化后的工艺处方为多功能匀染剂LDM用量1．0g／L、染液pH值3．04．5、浴比1：10。

Due to the low one-time success rate of dyeing polyester and spandex interknitted fabric with disperse brilliant blue BR, the effects of dyeing bath ratio, dyeing pH value, kind and amount of levelling agents on the dyeing properties were studied in the process of dyeing polyester and spandex interknitted fabric with disperse brilliant blue BR. The results show that after adding the levelling agent, the fabric K/S values decrease, but with the increasing of leveling agent, the color of the spandex is subsequently deepened; the optimum of levelling agent is multi-functional levelling agent LDM, the optimal process is that the dosage of LDM is 1.0 g/L, dye bath pH is 3.0-4.5, and bath ratio is 1：10.
