Abstract: Single jersey cotton knit fabric of 162 GSM was singed both chemically (enzyme treatment) and mechanically. Mechanically singed fabric exhibited more brightness and whiteness than chemically singed fabric and in the same manner chemically singed fabric resulted more yellowness than mechanically singed fabric. The color fastness to washing of the treated fabric experienced almost same results in both of the cases. On the other hand chemically singed fabric focused on prevailing more strength than mechanically singed one which was evaluated by bursting strength test. Eventually the CMC value of the chemically and mechanically singed, and then dyed, fabric remained within acceptable range. Microscopic view of the treated samples was also taken to capture the surface hairiness characteristics.
