This paper is focused on the properties of the yarns spun from ring and rotor spinning system, spun using bamboo / cotton blends and used for the development of the denim apparel fabrics. Twenty carded yarn samples of linear densities Ne 10 and Ne 16 were spun in three blend proportions of 70:30 B/C , 50:50 B/C and 30:70 B/C , and also in 100% cotton and bamboo fibers produced using ring and rotor spinning systems. Yarn quality like Unevenness (U %), Imperfections, Single yarn tenacity / elongation, yarn friction and yarn abrasion were evaluated. The experimental results indicated that the 100% bamboo yarns spun on the two spinning systems for both the counts Ne 10 & Ne 16 exhibited better evenness, lower imperfections, higher breaking strength and good abrasion resistance than 100% normal cotton yarns as compared to the other four yarn samples. Whereas among the ring and rotor spinning systems, better evenness, lower imperfections, higher elongation at break and good abrasion resistance were observed in the rotor spun yarns in all the blends as compared to its counterpart ring spinning system. However, single yarn tenacity of the rotor yarns were found to be lower than the ring yarns in all the blends. It is due to its bipartite yarn structure and the presence of wrapper fibers on the sheath of the rotor yarns. Yarn friction in both the counts does not show any significant difference in ring and rotor spinning systems. Among the three blend proportions, 70:30 B/C had resulted better quality characteristics than the other blends in both the spinning systems.
