Role of spinning process variables on dynamic process of hair formation in ring spinning

Yarn hairiness originates in the spinning triangle where individual or bundle of fibres are twisted and consolidated. It was supposed that, in a Z-twist yarn fibres in the left hand fringe were more responsible for the formation of hairs. In this study an attempt was made to verify different theories of hair formation and to study the effect of various processing parameters on the contribution of left hand fringe and right hand fringe of the spinning triangle to the hair length distribution. With the aid of CCD camera, it was planned to capture continuous photographs of spinning triangle to demonstrate the formation of different types of yarn hairiness. It was also planned to study the effect of parameters like traveller, roving hank and TM on the contribution of right hand fringe and left hand fringe of fibres in spinning triangle to the formation of the yarn hairiness and hair length distribution. © 2011 Universal Research Publications.
