| Abstract | ||||
| The object of the present work is to study the influence of the progress of cleaning operation on cleaning action, neps per gram and yarn characteristics. The results of industrial evaluations, using three varieties of Egyptian cotton fibers, To produce ring-spun yarns ranged from carded to combed qualities, are presented. For all cotton fibers, comparison of the processing performance of a three cleaning units with Masterclean concept are favourable to the new cleaning unit (MAC). The modern set alone provides up to 64% cleaning efficiency and lower lint loss at 460 kg/hr production. Also, the results emphasize the high trash removal consequently the cards had to handle up to 42% less trash as a results of this the card sliver turned out to be 60% cleaner. On the other hand, cotton tufts and card sliver contained considerably more neps than that processed through the conventional cleaning units. It was found that, within the limits of this study, the cleaning operation had appreciable effect on yarn quality. There were a significant differences in strength, ends down, uniformity and imperfections of ring spun yarn, between the two organization. For cotton fibers with a higher micronaire values, the values, the Masterclean concept achieve a better quality yarns than those obtained from conventional cleaning units. | ||||
