This fibre blend promises twice the warmth of wool

Developed by the Northern India Textile Research Association (NITRA) in collaboration with industry partners, the 80:20 wool-milkweed blend has demonstrated industrial viability, surpassing 100 per cent wool in thermal insulation, weight reduction, and softness.

“This blend can withstand temperatures as low as minus 50 degrees Celsius and is already attracting export interest,” Textile Ministry sources said. Plans are underway to showcase it at Bharat Tex from February 14 to 17 in Delhi.

Milkweed’s versatility extends across apparel, home textiles, and hygiene products, with the potential to replace conventional fibres in various applications. Ludhiana-based Ganga Acrowools has been engaged to integrate this blend into production.

Despite having a sheep population of over 7.4 crore, India produces 3.69 crore kg of carpet-grade wool annually but remains heavily dependent on imports, spending nearly Rs 1,800 crore in FY 2023-24 to source fine-grade wool like Merino for apparel.

“The quality of domestic wool is generally not superior. While Pashmina is exceptional, its production is limited. We needed a sustainable alternative,” ministry officials stated.

Milkweed is a perennial crop requiring minimal inputs. Once planted, it yields for up to 10 years, with production increasing annually. Farmers cultivating milkweed can earn Rs 1.5-2 lakh per acre, a significant boost over traditional crops like cotton.

Milkweed fibre is derived from silky, hollow filaments inside its seed pods. It offers superior thermal insulation — nearly double that of 100 per cent polyester nonwoven fabric.
