摘　　要：对涤棉混纺织物分别采用分散染料、直接染料染色,以及分散和直接染料碱性同浴染色,测试染色织物的最大吸收波长λm ax和K/S值等指标,以确定涤棉混纺织物用分散和直接染料碱性同浴染色工艺。结果表明,选择耐碱性的分散和直接染料在高温高压碱性浴中染涤棉混纺织物,对染色织物的λm ax和K/S值影响较小,染色牢度可以达到3级以上。Different dyeing processes were carried out on polyester-cotton blended fabrics with separated disperse and direct dyeing, and same bath alkaline dyeing with disperse/direct dyes respectively. The dyeing properties such as λmax K/S value and color fastness were tested, and same bath alkaline dyeing process was settled. The result shows that high temperature and pressure alkaline bath dyeing with alkaline-stable disperse and direct dyes exerted little influence on λmax, K/S value of dyed polyester-cotton fabric, and color fastness can reach more than 3 grade.
