Abstract
Polypropylene(PP) film yarns are generally classified as two types : slit yarn and split yarn. Production of PP film yarn has some advantage over the production of conventional PP filament yarn. In this study, high denier PP split yarn could be produced by introducing a cutting drum m/c in the drawing part of a slit yarn production line. It was possible to produce uniform and extensible PP split yarn and its woven fabric on a water-jet weaving loom. The tensile strength and strain of split yarn are 3.2-3.5 g/d and 11-14%, respectively. In the comparison of tensile test methods of woven fabric, higher value of tensile strength were obtained in the order of KS K 0520, KS K 0753, and KS F 2124. The weft picking condition of PP split yarn and sewing efficiency of its woven fabric, especially for the higher denier yarn and higher tensile strength woven fabric, are better than PP slit yarn and its fabric.
