Experimental results show that type C machine has the best carding effect, which is not ascribed to single factor control but the integrated design optimization and good performance of wire teeth. In comparison with the teeth design, the wire performance is another important factor that influences the perfommnce of modem high efficient production carding machine.展开更多
