Control optimization of crimp tension of polyester staple fiber ZHOU Xin-qiang , QIN Zhi-xiao , MA Shao-pu （ SINOPEC Luoyang Branch, Luoyang 471012, China） Abstract ：The importance of accurate measurement and smooth control of the tow tension in staple fiber crimp was analyzed. The key equipments which control the crimp tension such as tension detection device and the vector con- trol of the velocity sensor were introduced. The optimization measures in the actual operation, such as the correct installation of the speed measuring machine, the setting of the high limit value of the speed ratio, the optimization and adjustment of the acceleration / deceleration time were pointed out.
