Experiments evaluated the changes in low stress mechanical behavior of cotton and cotton/polyester yarns treated with enzymes. Different spinning systems manufactured yarns with different structures. Enzyme treatment conditions were identical for all samples. The treated yarns had a wide range of weight losses, which suggested that such structural parameters as fiber packing density, fiber distribution in the cross section, and fiber orientation might have affected the rate of cellulose erosion. The treated yarns in general showed higher thickness compression and higher compression energy, resulting in a marked improvement in softness. Most treated yarns also showed decreased values for bending stiffness and bending hysteresis. The extent of change in each property depended on the type of spinning system. Based on the changes in mechanical properties, it is predicted that fabrics made from these yarns would be softer and less stiff.
