An increase in the tencel content of tencel/bamboo blended yarns has a significant influence on the overall quality of the yarn in terms of yarn imperfections and mechanical properties, such as strength and elongation. The strength of 100% tencel yarn is more than tencel/bamboo blend yarn and 100% bamboo yarn. Elongation of bamboo yarn is more than 100% tencel yarn and tencel/bamboo blend yarn. Difference in fibre characteristics is the reason for this. When yarn unevenness is taken much difference is not seen. The observed variation is due to the variation induced by machine. It was also noted that the hairiness of bamboo yarn is lower than other yarns, close packing of tencel fibre makes the yarn diameter lesser when compared to pure bamboo and tencel/bamboo blended yarns. 100% bamboo yarn is having lower frictional co efficient than other yarns.
