Evaluation of mechanical properties of oak tasar silk waste/viscose blended knitted fabrics

Abstract

The present study was carried out to investigate the effects of blending oak tasar silk waste with viscose fibre to develop blended yarns for the construction of high quality knitted fabrics. The oak tasar silk waste and viscose blended yarn were prepared on worsted spinning system with three different blend ratios viz. 60:40, 50:50 and 40:60, spun into two different yarn counts (15 Nm and 20 Nm) for each blend ratio. Best four yarns out of total six were selected for further development of Single jersey knitted fabrics using circular knitting machine. The prepared knitted fabrics were evaluated for mechanical properties: breaking load and elongation, bursting strength, fabric growth, fabric stretch, abrasion resistance, snag resistance and thermal insulation. Results revealed that the addition of viscose fibre content improved the bursting strength, elongation percentage, abrasion resistance and snag resistance.
