摘要
采用分散金黄E-TD、分散红3B和分散蓝2BLN,对普通涤纶纤维和白竹炭涤纶纤维进行染色,研究染色温度、pH值、分散剂用量对分散染料上染率的影响,探讨这三种染料在竹炭涤纶纤维上的提升性能,并根据染色吸附动力学,计算三种染料在纤维上的染色速率常数和半染时间。结果表明,分散染料染竹炭涤纶纤维时,在120℃以上可获得较高的上染百分率;染色所需的最适pH值为5左右;分散剂用量过高,会导致染料利用率降低;染色速率常数则随着温度的升高而增大。
Dyeing of bamboo charcoal polyester fibers and ordinary polyester fibers with Disperse Golden E-TD,Disperse Red 3B and Disperse Blue 2BLN is carried out.The influences of dyeing temperature,pH value and dosage of dispersant on disperse dye up-take are studied.The building up property of three dyes on bamboo charcoal polyester fibers are investigated,and dyeing rate constant and half-dyeing time are calculated by adsorption dynamics.The results show that a higher dye uptake of disperse dyeings can be achieved at dyeing temperature above 120 ℃ and pH value of 5.The excess amount of dispersant results in lower utilization of the dye,and the dyeing rate constant increases with the increase of dyeing temperature.
