According to the interaction mechanism and positive synergic effectivitys of the surfactant, and by means of various research methods, we had optimized the components of spin finishes, such as smooth agent, cohesive agent, emulsifying agent and antistatic agent, and determined spin finishes formula finally. Also, the spin finishes had been produced and applied successfully in commercial production. The developed antistatic agent had a better performance on anti static electricity and smoothness, which had overcome the shortages of static electric interference and roughness in spinning of polyester staple fiber. At the same time, the agent had good humid suitability for solving the problems of the traditional antistatic agent, whose bad antistatic property and absorbing moisture to became sticky in low and high humidities, respectively. This research had formed a whole set of process package technology from the structure and properties of single component in spin finish, screening and optimization of the formula, to the match
