Analysis Of Different Types Of Washing Effect On Denim Fabric Using Different Concentration Or Parameters And Find Out The Best Concentration Or Parameter Which Gives Best Aesthetics Look & Also Evaluate The Strength Of Denim Goods According To The Physical & Wet Test Result

Abstract

Denim garments is the most preferred of today’s youth. The objective of this research is to provide an extensive overview of enzyme wash, bleach wash, acid wash for garments and find out best physical & chemical test result. The research paper are written for the garments washing professional for detailed casing information. In this research use indigo dyed denim garments and five parameter of  Lava cell NHC Cold (1 g/l, 1.5 g/l, 2 g/l, 2.5 g/l and 3 g/l) for enzyme wash, five parameters of Sodium hypochlorite (1 g/l, 1.5 g/l, 2 g/l, 2.5 g/l and 3 g/l) for bleach wash and five parameters of Potassium permanganate (2 g/l, 5 g/l, 10 g/l, 15 g/l and 20 g/l) for acid wash.

         After Enzyme wash, Bleach wash and Acid wash tasted all of sample according to ISO 105C06:2010 (Color fastness to Washing), ISO 105X12 (Color fastness to rubbing dry/wet), ASTMD-1425 (Tear Strength Warp/Weft). The research test result shows for enzyme wash sample no 5 give better performance and aesthetic look is better than other sample. For Bleach wash after test result sample no 5 shows color fastness to light, appearance after wash and color fastness to rubbing (Dry/Wet) performance better than other 4 samples. After GSM and tear strength test sample no 1 shows best performance than other 4 samples. But in the case of Acid wash after test we got sample no 5 color fastness to light, appearance after wash and color fastness to rubbing (Dry/Wet) performance better than other four samples. After GSM and tear strength test sample no 1 shows best performance than other 4 samples. But sample no 4 shows average result and sample no 5 shows very poor result for tearing test. Because high concentration of Potassium permanganate damage the fabric strength. That’s why in case of Bleach wash and Acid wash try to use medium concentration of Sodium hypochlorite (NaClO) and Potassium permanganate (KMnO₄).
