A Comparative Study Between Conventional & New Sustainable Denim Washing

Abstract

As the faded denim or old look denim is favored by the present youth, washing has become a vital issue for the technologists to change denim attire to satisfy the interest of the existing pattern. The primary elements influencing shoppers when choosing articles of clothing are stylish appearance and design. Denim articles of clothing are oppressed in mechanical washing to get the explicit appearance and handle. The washing and completing cycles are used with the end goal of design and extraordinary plans are applied for various impacts which are very noteworthy for promoting the denim market. Denim also plays a vital role in our economy. The aim of this paper is to find out the effect or changes that occur in the physical properties of denim when it is subjected to conventional wash or sustainable wash. To compare the conventional wash and environment-friendly sustainable wash. In the report, we try to figure out the changes in Tear strength, Tensile strength, GSM, EPI, PPI for denim after wash and before wash, and compared them to each other. Weight loss percentage also include in the report. We used denim fabric (75% cotton, 18 % polyester 7 % Viscose). We take a overall score and test report for sustainable wash and conventional wash. The EMI score for both test are measured with the help of lab. In the conventional score we found that Environment medium impact with the score of 63. Here (0-33 low impact), (34-66 medium impact) above 66 is high impact on environment which is not good for environment. In the sustainable wash the EMI score 47. Which is slightly less than conventional wash. We find Sustainable wash chemical, water impact, chemical consumption are less than conventional wash. We try to find out new technology in denim wash, which will be fruitful for this sector and sustainable wash. In the report we try to figure out after wash and before wash comparison in denim. We see that for GSM weight loss percentage is 2.97% and Tear strength weight loss% for warp way is 16.17% and for weft strength loss is 20.46 % . Tensile strength loss % is 24.7% for warp way and for weft way strength loss % is14.19%. In this paper with the help of our Teacher, we tried to know some upcoming technology which is necessary for denim development, like ,laser machine, ozone machine effect on denim wash. With the use of these machine denim development will be improved in a sustainable way.
