Study on Hairiness of the Yarn Produced using Cotton and Polyester/Cotton Blended Roving with Different Traveller Number and Twist Level

MURUGESAN, M. | SENTHILKUMAR, T.
The edge fibres of the drafted strand coming from the front roller are either collected as a waste or poorly wrapped over the yarn structure. This poorly wrapped fibers forms hairiness on the surface of the yarn and also increases its protruding length during post spinning process. In this study, hairiness of the yarn were analysed by varying the process parameters that will affect the drafted fibre strand width and hence the amount of poorly wrapped fibres on the yarn surface such as Total draft, break draft, traveller number and twist. The hairiness of the yarn significantly increases while increasing the total draft and break draft. The hairiness of the yarn decreases with increase in the yarn twist level. The increase in traveller weight decreases the amount of hairiness significantly in 50 Ne combed cotton and 50 Ne polyester/cotton blended yarn whereas, in 80 Ne combed cotton yarn, increase in traveller weight significantly increases the yarn hairiness.
