ABSTRACT: At present ring slub carded yarn is very popular to produce value added product for ornamentation purpose in the apparel industry. During spinning different parameters influenced the spinning performance. The main aim of this study was to investigate the effect of spindle speed as well as traveller weight on yarn quality. The Ne 28, Ne 30 and Ne 34 carded slub yarns were produced at the spindle speed of 15,500 rpm, 16,000 rpm, 16,500 rpm, 17,000 rpm and 17,500 rpm on the ring frame with using traveller number 3/0, 4/0, 5/0 and 6/0. The yarn properties like mass variation percentage (CVm%), unevenness (U%), hairiness, yarn breakage rate, yarn imperfection were investigated. It was found that traveller number 5/0 showed lower Um%, CVm% for Ne 28 and Ne 30 carded slub yarn compared to traveller number 3/0 and 4/0. On the other hand traveller number 6/0 showed better Um%, CVm%, thin places (-50%)/km and end breakage% for Ne 34 carded slub yarn compared to traveller number 4/0 and 5/0. It was also observed that increasing end breakage rate as the spindle speed of ring frame was increased.
