摘　　要：通过大量试验,研究和探讨了S—PC盐用于T/C一浴一步法染色时的作用机理,提出S—PC盐是通过其本身在碱性中水解的S_N1反应,使染浴pH值从碱性滑移到酸性,详细分析了各种活性基在一浴一步法染色工艺中受S—PC盐的影响情况,从理论上说明了有关染料的适用性,并探讨了应用该助剂的染色工艺。The action mechanism of salt S-PC when used in one-bath one-step T/ C dyeing was studied through plenty of expts, and it was suggested that the SN1 reaction of the alk. hydrolysis of the salt it self make the dye bath pH glide from alkaline to acid. The influences of the salt on the various active sites in the one-bath one-step dyeing were analysed in details. The suitability of the related dyes was stated the oretically, and the dyeing process with this salt was searched.
