Migration Behaviour of Polyester/Viscose Blended Rotor Spun Yarns

B.R. Das, S.M. Ishtiaque and R.S. Rengasamy
Many researchers have reported the fibre migration behaviour of blended ring yarns; but very few researchers have studied the phenomenon of fibre migration in blended spun yarns produced in new spinning systems like; rotor and air-jet spinning. The earlier studies on blended rotor spun yarns were represented by the average behaviour of the different components; which motivated to study the migration behaviour of individual components along with their average behaviour in the rotor spun blended yarns in terms of three parameters, Mean Fibre Position (MFP), Mean Migration Intensity (MMI) and Root Mean Square Deviation (RMSD)-using tracer fibre technique. Five blend proportions; 100% polyester, 67/33 polyester/viscose, 50/50 polyester/viscose, 33/67 polyester/viscose and 100% viscose was considered for analysis of effect of blend proportion on the migration behaviour of rotor spun yarns. Statistical analysis was carried out at 95% confidence level to bring out the specific trend executed by the yarns. Six number of contrasting tracer colours was established and exploited to study the migration behaviour with higher precision. The studied migration behaviour showed that the migration parameters don’t follow any specific trend with increase in the viscose or polyester content. 100% polyester yarn has lower MFP and higher MMI than the 100% viscose yarn. The polyester/viscose 33/67 has highest value of RMSD than the other blends.
