Abstract
Fabric and yarn damage caused by small increments of frictional abrasion in an Accelerotor were evaluated for three pairs of matched fabrics. Variables investigated were fiber content, blend level, weave, finish, and amount of abrasion. Quantitative measures of changes in yam and fabric properties were evaluated. Photomicrographs of fabric surfaces, yarns removed from fabrics, and of fabric cross sections were also evaluated.
Fabrics with crease-resistant finishes tended to rank higher in appearance characteristics, while those with the pure finishes tended to rank higher in performance factors related to strength. Crease-resistant finishes did not necessarily accelerate abrasion damage.
Evaluation of abrasion damage generally showed a relationship between increased yarn crimp and increased thread count, between loss in yarn tex and loss in yarn strength, and between loss in fabric strength and loss in yarn strength. A double rupture was observed in the breaking-strength behavior of the durable-press polyester/cotton fabrics after low levels of abrasion. This double rupture disappeared after higher abrasion levels.
