Abstract
The formation of belts and their influence on tenacity of rotor-spun yarns have been studied. When two fibers of different lengths are blended together, the longer fiber predominates as belts, with the result that the composition of constituents in the form of belts is changed considerably. An increase in twist density increases the number of belts but has no influence on the composition of constituents in the belts. Neither differences in denier nor in fiber type has any marked influence on the composition of belts in blended yarns. Contrary to the generally-held view, it has been observed that belts can help in enhancing the strength of rotor-spun yarns. When a small percentage of long viscose fiber is blended with a short staple cotton, the blended yarn strength improves due to the reinforcement of the yarn matrix through belts. The influence of belts is most pronounced when the twist factor used is low.
