Abstract
Nine multifilament yarns and 18 staple yarns were tested on a modified Walker Abrader using the same low tension for all yarns. To correct all filament yarns to the same fineness (100 den.), multiple strands of filament viscose 100/40 were tested, and a correction factor was obtained. In the same manner, multiple strands of Kuralon 80/2 were tested to obtain a correction factor for staple yarns. The Walker Abrader results for staple yarns were also corrected to 100 den. After the results had been corrected, acetate filament yarn was found to have the lowest abrasion resistance and nylon filament yarn the highest abrasion resistance among the filament yarns. In the staple yarns, acetate 20/1 had the lowest abrasion resistance, and Dacron 60/2 (worsted) had the highest abrasion resistance. Comparing staple and filament yarns, acetate staple 20/1 had the lowest abrasion resistance, and nylon 100/40/2.5 filament had the highest abrasion resistance. In general, the abrasion resistance of filament yarns was greater than the abrasion resistance of staple yarns.
