Effect of cotton waste and spinning parameters on rotor yarn quality

In this paper, we study the effect of cotton wastes and different spinning parameters on the rotor yarn quality. Statistical models are established to predict a total quality index and the optimum spinning conditions by using maximum cotton waste rate. The results indicate that rotor parameters (diameter, form and speed) have an effect as significant as waste proportion. With optimum spinning conditions, the secondary raw material can be mixed in a proportion between 15% and 25% without hardly noticeable changes in quality.
