摘　　要：在氯铂酸催化下通过硅氢加成合成端羟乙基硅油(di HE-PDMS),并将其与端羟丙基硅油和羟基硅油分别用于硅丙乳液合成,比较了不同活性硅油对硅丙乳液合成的转化率、凝胶率、粒径及其分布、胶膜吸水率和印花织物表面形貌的影响,并测定了织物印花性能。结果表明:以di HE-PDMS为原料合成的硅丙乳液具有纳米级粒径(115.7 nm),高单体转化率(98.60%)和极低凝胶率(<0.01%)。印花织物表面形貌分析显示,硅丙聚合物和羟基硅油合成的硅丙聚合物能较好地对颜料粒子进行包覆,但仍有少量颜料粒子未被端羟丙基硅油合成硅丙聚合物所包覆。硅丙乳液印花的织物具有特别柔软的手感和更高的色牢度。Dihydroxyethyl-terminated polysiloxane （diHE-PDMS） was synthesized from dihydrogenterminated polysiloxane and hydroxyethyl acrylate by hydrosilylation. Subsequently, diHE-PDMS, dihydroxypropyl-terminated polysiloxane and hydroxyl-terminated polysiloxane were applied in the synthesis of silicone-acrylate emulsion. The effect of polysiloxanes with different hydroxyl groups on the monomer conversion, gelation rate, particle size and its distribution and the surface morphology of silicone-acrylate emulsion printed fabrics were studied. Properties of pigment printed cotton fabrics were also investigated. Silicone-acrylate emulsion synthesized using diHE-PDMS possessed small particle size （115.7 nm） and exhibited high monomer conversion （98. 60% ） and extremely low gelation rate （ 〈0.01% ）. Surface morphology analysis of pigment printed fabrics showed that the pigment particles could be coated well when applying silicone-acrylate emulsion using diHE-PDMS and hydroxyl-terminated polysiloxane as the raw materials, and water absorption of their films was low （7.50%）. Whereas a few pigment particles still have not been coated well by the silicone-acrylate copolymer prepared from dihydroxypropyl-terminated polysiloxane, and its water absorption is high （33. 50% ）. Moreover, the addition of polysiloxane could remarkably improve the hand feeling of pigment printed fabrics.
