P085_0226_ EFFECT OF PROCESS PARAMETERS ON RECOVERY BEHAVIOUR OF POLYESTER-COTTON BLENDED ELI-TWIST AND TFO YARNS

Abstract

The relationship between magnitude of instrumental measurement of the elastic recovery properties and some yarn parameters has been studied. As compared to Eli-Twist yarns, TFO yarns are better in terms of recovery characteristics. In general, yarns with high polyester content in the fibre mix having higher immediate elastic recovery and lower permanent deformation. High amplitude of extension reduces the immediate elastic recovery and delayed elastic recovery. Coarser yarns have high immediate elastic recovery and low permanent deformation.
