It is observed that dry abrasion renders the fabrics less stiff, damp abrasion stiffens them, while the high proportion of polyester fibre in the blend Improves the performance in physical/mechanical properties and abrasion resistance. Determination of a simple paired t-test showed no significant difference between unabraded and abraded (dry and damp). and between the dry-abraded and damp-abraded fabrics with respect to physical/mechanical properties except for compression % at 19 kNm^-2 pressure and frictional residual curvature at 95% confidence interval.</span>
