The paper provides comparison of properties of 100% cotton yarn with those of two cotton-polyester blended yarns of 50/50 and 20/80 blend ratios. In this regard three types of yarns were produced in the ring frame and for each type two different counts were produced. The blending was carried out in the draw frame. During processing, the settings and parameters were adjusted for optimum performance. After production at each stage samples were collected and investigated. The properties that investigated were count, yarn faults, yarn irregularity and strength. The study showed that, in ring frame it was possible to maintain higher spindle speed and lower twist multiplier for 50/50 & 20/80 blended yarns than 100% cotton yarn. Between 50/50 & 20/80 blended yarns, it was possible to maintain higher spindle speed and lower twist multiplier for 20/80 blend than 50/50 bend. It was observed in all cases that as the percentage of polyester increase the U% i.e. the irregularity in the sliver/yarn decreases. It was also observed that yarn faults decreased with the increase of % of polyester in the yarn. The yarn strength of 50/50 & 20/80 blended yarn was higher than that of 100% cotton and strength of 20/80 was higher than that 50/50 blended yarn.
