Polymethylsiloxane/polyacrylate copolymer emulsion was synthesized by a drop-adding monomer emulsion method. The TEM photos demonstrate the core-shell structure of latex particles. The FTIR, ¹H NMR and DSC results indicate that hydrogen-containing polymethylsiloxane reacted with acrylate monomer to lead to chemical bond formation, and no hydrolysis occurred. With this copolymer emulsion as a coating agent for cotton fabric, the fabric is not sticky under 60℃ and has no crack under -10℃. When it is used as a calico-printing adhesive for decorative fabric, the fastness of the fabric under dry and wet friction is in grade of 5 and 4, respectively, and no change in color difference was found in the under-cloth which also did not turn to yellow when sublimation fastness was measured at 200℃.
