摘　　要：用有机硅及丙烯酸酯单体通过乳液聚合制备了具有核壳结构的共聚物乳液。探讨了聚合条件与单体转化率的关系，用透射电镜照片、红外光谱图对聚合物的结构进行了表征，测试并分析了以该乳液作为印花粘合剂进行涂料印花后棉织物的性能。结果表明，核壳型乳液最佳的合成条件是复合乳化剂用量为6％，引发剂用量为0．6％．反应温度为80～85℃，并且随着聚合物中有机硅含量的增加，印花织物的刚度逐渐减小，织物的颜色性能如L、c及K／S值均显著增加，说明印花后织物的手感柔软，织物的色牢度有相应的提高。The emulsion with core-shell structure was prepared with organosilicon and acrylate monomers through emulsion polymerization. The correlation of polymeric condition and conversion rate of monomers was investigated.The structure of copolymer emulsion was characterized by TEM and FTIR. Pigment printing of cotton fabrics with this emulsion as binder was performed and the properties of the printed fabrics were analyzed. The results show that the optimal polymerization conditions for the core-shell emulsion are as follows ： 6 % compound emulsifier; 0.6 % initiator; reacting at the temperature 80 ～ 85℃. The rigidity of the printed fabrics decreases gradually as the content of organosilicon monomers in the polymer emulsion increases, and the colour data such as L, C and K/S value of the printed fabrics increase significantly, indicating that the primed fabrics have a soft hand and improved colour fastness.
