Briefings

MIT researchers developed a thermoplastic yarn made from two polyethylene variations that mimics stretchy elastic fibers. Unlike conventional spandex-polyester blends requiring separation, this new material can be melted and respun without losing strength or flexibility after ten cycles. The lead researcher Svetlana Boriskina notes the yarn can now be knitted and woven, enabling a potential circular textile economy where garments could be recycled into new yarn.

Key points

• MIT researchers created a thermoplastic yarn from two polyethylene variations that mimics stretchy elastic fibers.
• The yarn retains strength and flexibility after ten cycles of melting and respinning, allowing for knitting and weaving.

Context

This finding addresses the high volume of textile waste in the US, where 81 pounds of clothing are thrown out annually with few recycling options. The breakthrough offers a pathway to reduce this waste by enabling garments to be melted and repurposed into new yarn, supporting a more sustainable circular economy.

Limitations

Evidence covers only the creation and testing of the thermoplastic yarn; it does not include data on actual garment production, market adoption, or environmental impact assessments beyond the recycling cycle.
