To improve cotton carding quality, the effect of speed ratio between cylinder and taker-in on card sliver, breaker sliver and intermediate sliver were investigated under different speeds of cylinder and taker-in. The parameter correlation between card sliver and breaker sliver, intermediate sliver was analyzed using SPSS. The results showed that when the taker-in speed ranges from 500 r/min to 800 r/min, the length-related parameters changed a little, even under the same taker-in speed with different speed ratios. However, the numbers of nep and impurities had an obvious decreasing tendency with the increase of taker-in speed and cylinder/taker-in speed ratio. In the case when the taker-in speed is in the range of 850 to 900 r/min, the length-related parameters decreased and the numbers of nep and impurities increased remarkably with the increase of taker-in speed and cylinder/taker-in speed ratio.
