  Abstract:In order to save production cost，the requirements of raw materials with high impurities and short fiber content for card clothing in rotor spinning are introduced，forward solutions are put forward to solve the problems such as reversing of reused cylinder card clothing and deformation of reused flat clothing in card clothing binding from ring spinning.By comparing the yarn quality of soft twist OEC 58.3 tex yarn spun by new card clothing and reused card clothing，it is pointed out that the sharpness of reused cylinder and doffer card clothing is worse than that of new card clothing.The effect of removing impurities can be increased by improving the speed of taker-in，optimizing the gauge of mote knife and small leakage bottom，increasing the cotton droppings，increasing the force of taker-in removing impurities，and reducing the pressure in the cylinder-flat carding area.Doffer-cylinder gauge is small，while increasing the weight per unit of card sliver，reducing tension drafting，which can reduce the production of short fibers.The gauge of reused flat clothing should be tight to increase cleaning efforts.The spinning quality of reused card clothing can meet customers’requirements，and the cost of each machine can be saved about 12，000 yuan.Reused card clothing needs to be combined with many factors，such as the state，raw materials，environment，process，equipment technology and operation level of reused card clothing.
Key Words:rotor spinning；ring spinning；card clothing；card clothing reusing；soft twist OEC 58.3 tex yarn
