The Effect of Twist Direction and Number of Twists of Silk Yarn on Plain Fabric Properties Classified by S on S Twist

Abstract

This is a study on the effect of twist direction and number of twists on silk yarn classified by S and S on S to its fabric properties such wrinkle recovery, stiffness, tensile strength, tearing strength and abrasion resistance. The silk yarn 27–29 / 6 Denier (D) were twisted by S at 200 twists and twisted by S on S on 5 levels of 80 / 80, 100 / 80, 120 / 80, 140 / 80 and 160 / 80 twists / meter.
From the results, it was found that fabrics with S on S impart better qualities than fabric produced by yarn twist with S on factors of wrinkle recovery, stiffness, tensile strength, tearing strength and abrasion resistant. The average was 6.73 %, 19.782 %, 2.203 %, 1.654 % and 40.81 % respectively. While on fabric elongation at break with S on S twist has lower qualities than S at 2.245 %.
