摘　　要：研究碱预处理后,用DMAC(氯化1,1-二甲基-3-羟基氮杂环丁基铵)处理的棉纱进行活性染料染色的可染性,以及影响染色棉纱色强度的因素,结果表明用本法比用DMAC处理而未经碱预处理染色棉纱的色强度高,而且得色率也高。An investigation was made on dyeability of cotton yarn with reactive dyes after the treatment first with alkali and then DMAC(1,1-dimethyl-3-hydroxyazetidinum chloride). The factors affecting the colour yield was also studied. Reasults indicate that the colour yield of dyed yarn pretreated with both of alkali and DMAC is higher than that only with DMAC and conventional process.
