摘　　要：选用耐双氧水的直接混纺染料对纯棉织物进行一浴法退煮漂染色。探讨了染料的耐双氧水性能、氢氧化钠用量和双氧水用量对染色的影响,并与传统的二浴法进行比较。结果表明,一浴法染色织物染色牢度与传统的相当,匀染性也较好,但其K/S值稍低,染料的利用率较小;由于一浴法处理的织物上可能还残留少量棉籽壳,故适用于深色织物的染色。Desizing, scouring, bleaching and dyeing of cotton fabric are carried out in one bath with D-type direct dyes of good stability to hydrogen peroxide. Influences of stabilities to hydrogen-peroxide of the dyes, dosages of sodium hydroxide and hy- drogen peroxide on dyeing results are discussed. The results show that compared with the conventional process, the dyeings with one-bath process feature similar color fastness and better evenness, but a little lower K/S value and utilization ratio of dyes. This one-bath process is suitable for dyeing in deep shade because of a small quantity of residual cotton seed hull on the fabric.
