Influence of yarn structure, sizing ingredients and type of sizing on properties and performance of sized yarns: Part I-evaluation of sizing process using Zweigle G551 weavability tester

摘要

The average and minimum number of abrasion strokes to failure, rate of deterioration in tensile properties when subjected to simultaneous flexion and abrasion, and the effect of cyclic extension on sized yarn strength at different size concentrations have been studied. It is observed that the number of abrasion strokes till break is higher in case of grey ring yarn than that in case of the yarns sized with thin boiling starch(TBS)because the fluff generated on the surface of the grey yarn acts a protective shield. The gain in strength after sizing is greater for yarns.
