摘要
对新开发的耐碱性分散染料,分散橙BROB、分散红900、分散红902及分散蓝825的染色性能进行了研究。研究表明,这类染料具有优异的耐强碱稳定性,在pH值12的NaOH体系中,染色性能稳定,K/S值和色光无明显变化;染料的上染率和提升力高,染色牢度优异,适合于涤纶碱性浴染色,为涤纶织物以及涤棉混纺织物前处理与染色同浴的短流程工艺提供了可能。
The dyeing properties of novel alkaline-stable disperse dyes Disperse R-900, Disperse R-902, Disperse orange B ROB and Disperse B-825 are studied. The results show that novel alkaline-stable disperse dyes feature excellent stability in NaOH solution of pH value 12, good dye uptake and fastnesses without significant change of K/S value and color shade, and are suitable for dyeing polyester in alkaline bath, which provides the possibility for one bath pretreatment and dyeing of polyester/cotton blended or polyester fabrics.
