Can you believe in India, around 3.9 million tons of domestic post-consumer textile waste comes out annually of which only 4% is recycled. Most of these textile wastes go to landfill and remain there for hundreds of years.
To solve the issue and recycle the waste is a Challenge. The researchers from the Indian Institute of Technology (IIT), Delhi has developed a method to recycle denim waste to knitted garments without compromising quality. Waste denims were recycled into yarns ensuring minimum damage to the fibre properties by optimising the process conditions.
Recycled yarns were then blended into knitted fabric using the seamless whole garment technology. Knitted garments were produced varying the recycled yarn content from 25% to 75%.
The research team led by Prof. Abhijit Majumdar and Prof. B.S. Butola of Textile and Fibre Engineering department found that up to 50% of recycled yarns can be used in knitted clothing without deteriorating the feel of the product.
The research paper has been highlighted in a recent publication of Journal of Cleaner Production. Another key aspect of this research was to quantify the environmental benefits through life cycle assessment (LCA) in the Indian context.
