In this study, the mechanical behaviour of parent as well as wet spliced cotton denim yarns were compared before and after sizing in order to evaluate the sizing contribution and to predict the effectiveness of sized splices during weaving. The sizes used were natural (CarboxyMethylCellulose size) and synthetic (Acrylic size).It is found that splicing improves the breaking strength of both parent and spliced yarns, while sizing improves the elongation at break of only wet pneumatic spliced yarns. The same results were obtained under cyclical tensioning.

Abstract:

In this study, the mechanical behaviour of parent as well as wet spliced cotton denim yarns were compared before and after sizing in order to evaluate the sizing contribution and to predict the effectiveness of sized splices during weaving. The sizes used were natural (CarboxyMethylCellulose size) and synthetic (Acrylic size).It is found that splicing improves the breaking strength of both parent and spliced yarns, while sizing improves the elongation at break of only wet pneumatic spliced yarns. The same results were obtained under cyclical tensioning.
