摘　　要：通过研究不同类型的表面活性剂对聚乳酸纤维的分散染料染色,发现两种双子型表面活性剂双八烷基二甲基溴化铵(D821)和双十烷基二甲基溴化铵(D1021)对上染百分率和染色深值的提高有显著作用。双子型表面活性剂不仅提高了分散染料的溶解度,而且提高了聚乳酸纤维对染料的吸附能力,促进了分散染料从染液向纤维转移,从而改善了分散染料聚乳酸纤维的上染性能。相比较而言,D1021比D821具有更好的提高染料溶解度的能力,对纤维的吸附能力也更强。Bisoctyl Dimethyl Ammonium Bromide（D821）and Didecyl Dimethyl Ammonium Bromide（D1021）are two kinds of more effective surfactants in improving dyeing property of PLA fiber dyed with disperse dyes,which are found after different ion kinds of surfactants are selected.There are two aspects of the principle about the two kinds of cationic Gemini surfactant.On the one hand,the surfactant can increase the solubility of disperse dyes in the dye bath,on the other hand,the surfactant has strong adsorption to the PLA fiber,which are beneficial to shift more disperse dyes to PLA fiber from the dye bath.In comparison,D1021 is better in improving the solubility of disperse dye and higher stronger adsorption on PLA fiber than D821.
