Аннотация Young people as well as older people have now great passion for the denim cloth. Today jeans are available in many colors and designs. In this study we tried to reveal the difference in between two types of cellulase enzymes acid and neutral (powder) enzyme. To do this, denim samples were collected and prepared according to the recipe of equal amount of enzyme by varying the liquor ratio. Basically there were no differences found in between acid and powder enzyme on different fastness properties like rubbing, washing, perspiration, light fastness test. But there was a significant difference in weight loss%. Acid enzyme exhibited little bit more enzymatic effect than powder enzyme and it also showed more weight loss % . But the neutral enzyme required less money rather than acid enzyme and no need to control pH, easy to use. Moreover, lower liquor ratio gave higher abrasion. Acid enzyme gave more back staining than neutral enzyme.
