Increased Interest in Sustainable Fibers is Emerging
Interest in new sustainable fibers for developing advanced products is emerging.
Given the global trade volatility, textile manufacturing countries like India and developed economies like United States are racing to develop cost effective products and processes. Additionally, sustainability is on the front burner to remain competitive and innovative in manufacturing.
The Northern India Textile Research Association (NITRA) has been pioneering efforts to utilize milkweed fibers in developing advanced textile products like insulation wear, army wear, and more.
On July 19, Dr. M. S. Parmar, NITRA Director General, presented farm-to-fabric aspects of milkweed fibers in a meeting organized by the North India Section of the Textile Institute (NISTI), U. K.
Dr. R. A. Lal, Chair of NISTI, opened the event with the history of milkweed cultivation in India and its opportunities for use in advanced textile products.
Dr. Parmar highlighted milkweed’s unique properties and compared the characteristics with cotton and polyester. Milkweed fibers have high moisture regain of about 11%, and its tenacity and length is on par with cotton.
Advanced products like sleeping bags with milkweed insulation have been developed. These products were displayed to the Honorable Narendra Modi, Prime Minister of India, and the public during the Bharat Tex 2025 event. The Prime Minister discussed the medicinal properties of milkweed and encouraged NITRA to develop milkweed products.
NITRA’s collaboration with India’s National Botanical Research Institute will enable productivity improvement. According to Dr. Parmar, the yield per acre is about twice that of cotton and requires less water and other chemical resources.
Being a perennial plant, it is expected to yield fruit through 10 years, with yield increasing progressively from the second year.
In addition to process optimization and product development, NITRA is also engaged with training programs for farmers to grow milkweed plants in the states of Rajasthan, Punjab, and Haryana. NITRA is engaging with social groups such as Ruma Devi Foundation to train ladies in the cultivation and value-addition of milkweed fibers and byproducts.
While NITRA is promoting milkweed fibers, there is growing interest in hemp fibers in the United States. Cotton Incorporated is pushing cotton into hygiene products.
A collaborative effort between the Nonwovens & Advanced Materials Laboratory at Texas Tech University, and Jayalakshmi Textiles in Aruppukkottai, India, has resulted in using low grade cotton to develop value-added textiles. This oil absorbent product has been evaluated in oil fields in the Thiruvarur area and Ennore thermal plant.
While the interest and advancements in these sustainable fibers are encouraging, cost effectiveness in comparison with synthetic fibers is a key factor in enabling commercial success.
