In the carding machine, waste elimination takes place under the taker-in and the carding action takes place between the segment of cylinder and flats. The speed of taker-in affects the elimination of impurities and amount of waste generation. The speed of cylinder affects the degree of carding, waste generation and sliver quality. In general, high cylinder speed results high production. Increasing the cylinder speed is a sensitive operation as it has higher risk of negative influence on waste generation and sliver quality. Exceeding higher cylinder speed can lead to good fiber breakage, good fiber damage and higher neps generation which decreases the quality of card sliver. Again, lower cylinder speed increases the quality of card sliver but reduces the rate of production which is not financially viable. In this paper, it is intended to establish cylindrical speed relationships with card waste and card sliver quality produced by cotton carding machine.
