Abstract:In order to improve the service life and carding effect of taker-in MCC，the carding characteristics and the states of different wear parts of taker-in MCC are analyzed.The design mechanism of taker-in MCC with high wear-resisting is described in detail from the aspects of material optimization，reasonable design of tooth profile，bevel tooth treatment，tooth tip width optimization，heat treatment process optimization and surface enhancement coating treatment.The performance and spinning effect of the taker-in MCC with high wear-resisting are analyzed by taking carding different fibers with different carding machines as examples.The results show that the friction and wear of the fiber on the tip，front，side and edge of taker-in MCC as well as the chemical corrosion wear will lead to the decrease of the combing efficiency and the shortening of the service life of taker-in MCC.High wear-resisting taker-in MCC rack is smooth in surface，wear resistance，sharpness，flatness and quenching uniformity of the taker-in MCC are greatly improved.The taker-in MCC has the characteristics of good carding effect，little fiber damage and long service life.
Key Words:taker-in；MCC；rack；surface strengthening；wear；high wear-resistance；carding；service life
