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.展开更多
The blending of different fibers is done for the manufacturing of yarn to ensure the presence of multiple properties in the resultant yarn which is impossible if we use only one type of fiber.

Tencel is regenerated cellulosic fiber & flax is natural bast fiber. Tencel shows more versatility than flax. Tencel has a softer feel with a variety of end uses. Tencel is wrinkle-prone and stiff. Tencel shows extreme strength even in wet conditions and at the same time, it is more durable than linen. The most important fact is that the heat dissipation property of flax is 5 times higher than wool & 19 times higher than silk. Linen clothing can lower the body temperature by 3 to 4 degree celsius in hot weather than clothing made of wool and silk. A yarn made of both Tencel & linen (50:50) will contain the properties of both fibers. At the same time, we can make this yarn more aesthetic by incorporating a slub. It was observed that the slub yarn made by blending Tencel and flax fiber shows better properties than the slub yarn of the same count made from the blending of cotton and flax.展开更多
