A Sustainable Denim Washing Process Uses Coconut Husk Instead of Conventional Stone

Received Date:12 October 2023, Accepted Date:30 October 2023, Published Date:05 December 2023


Objectives: The main aim of this study is to ensure sustainability in the garment washing sector by replacing stone wash with coconut husk. Methods: The authors just replace stone with coconut husk in the conventional recipe. Three types of denim fabric have been used to test these experiments. 220-400gsm denim fabric has been chosen for these experiments with 200-300 gm coconut husk. There are different types of sustainable chemicals like Asucel wf (waterless enzyme), Lanzene Row A2 (activator) and Novopol SE 550 powder has been used. Finding and Novelty: Denim washing with coconut husk provides positive feedback, like stone washing. The using of coconut husk reduces the liquor ratio compared to conventional stone denim washing because of absorbency properties of coconut husk. Results reveal the satisfactory values in acid and alkali medium because of good absorbency properties of coconut Husk. After washing with coconut shell meet the minimum requirements of dimensional stability (Length±3%, width±3%) compared to stone denim wash. The tearing strength and tensile strength also meet the minimum requirements (≥30 N and ≥250 N) compared to stone denim washing. Introducing the alternative in denim stone washing, the coconut husk shows a perfect result rather than stone one without compromising the trendy looks.
