Effect of Weft Yarn Type and Weaving Parameters on Surface Roughness and Drapeability of Woven Fabric

Comfort is a qualitative feature and one of the requirements that modern garment buyers place on their purchases. The purpose of this work is to study the effect of weft yarn type, weft yarn tension, warp yarn tension, and weft density on drape and surface roughness properties of cotton plain woven fabric. Each factor was treated at two levels such as yarn type (ring-spun and rotor-spun), warp tension (1 kN and 2 kN), weft tension (PFT/B- and PFT/B+T) and weft density (14 picks/centimeter (PPC) and 18 PPC). Full factorial design was used to design the experiment and analyze the results of the experiment. The results of the analysis showed that fabric produced from ring-spun yarn has smoother surface and better drape than fabric produced from rotor spun yarn. As weft and warp yarn tension increased, the surface roughness of the fabric increased and fabric drape decreased. On the other hand, fabric drape decreased as the weft density increased and the surface roughness of the fabric increase as weft density decreased.
