Abstract
This study focuses on comparison between Enzyme Wash and Bleach Wash (Traditional vs. Sustainable Washing Machine) the physical and color fastness to rubbing properties of denim garments. For this experiment indigo dyed cotton denim garments (trousers) were chosen which were 98% cotton and 2% spandex and processed by enzyme with the concentration of 2 g/l, and the temperature of 45°C. In another work, enzyme treated denim garments were used for bleach wash with the concentration of 2 g/l, temperature 45°C and those samples have been processed by traditional and sustainable washing machine. After completing process, the sample properties have been compared like rubbing, tearing and tensile properties. After comparing result the color fastness to rubbing of enzyme wash was poor in traditional and sustainable machine and tensile strength, tearing strength properties down in traditional machine but the color fastness to rubbing of bleach wash was good in sustainable machine than traditional machine and a little bit lesser tensile and tearing properties in sustainable process.
Highlights
Sustainability in denim washing has become burning issue
This study focuses on comparison between Enzyme Wash and Bleach Wash (Traditional vs. Sustainable Washing Machine) the physical and color fastness to rubbing properties of denim garments
From view of washed denim garments (Figures 1-4), it has been seen that more enzyme effect by traditional washing machine but good bleach effect seen by sustainable machine
Summary
Popularity of denim garments has been increasing day by day in the world market but in denim industry 100 liters of water are used to wash a single pair of jeans during the production process. This translated into the denim industry consuming around 18 billion liters of water per year. Enzymatic treatment removes size materials, starch, to bring high and low abrasion of denim garments, give a cleaner, smooth surface, increase comfort ability and quality of denim garments which are used to replace chemical and mechanical process [5] [6] [7] [8]. This work was done for looking for the best option for enzyme and bleach wash by sustainable and traditional washing machine
