摘　　要：在棉/真丝混纺织物Drimarene活性染料一浴一步法染色中,为提高棉和真丝的同色性,在染浴中加入适量的缓染剂,探讨了缓染剂种类及用量对染色同色性,上染速率和固色率的影响。结果表明,阴离子型缓染剂Lyogen AB可减缓活性染料对真丝纤维的上染速率,改善棉/真丝织物活性染料同浴染色的同色性,且不影响染料利用率。One-bath one-step reactive dyeing of cotton/silk blends was carried out with retarding agents to improve union-color property. Influences of type and dosage of retarding agent on union-color property, dyeing rate and fixation yield were dis- cussed. Results showed that anionic retarding agent Lyogen AB could reduce dyeing rate of reactive dyes onto silk and improve union dyeing without negative effect on utilization ratio of reactive dyes.
