Abstract
In this study, effect of normal and enzyme wash on the physical properties of indigo dyed 2/1 plain rib cotton fabric was examined. ISO and ASTM standard were followed separately for testing tensile strength, tearing strength, pilling resistance, color fastness to light, color fastness to rubbing, color strength and fabric weight. The fabric samples were subjected to neutral and acid enzyme wash, then the test results were compared with the normal washed samples. Enzyme wash reduced the tensile strength (13% in warp and 16.04% in weft), tearing strength (35.4% in warp and 29.6% in weft), GSM (1.8%), color strength (0.91% lighter) and improved color fastness to rubbing (rating for dry rub 5 and wet rub 1-2) of the sample. On the other hand, normal wash showed lower pilling resistance (grade2). The results are comparable with the results found from similar wash effect on cotton twill fabric.
