Long Advance, of Taipei, Taiwan, claimed the Eco Award at this week’s Performance Days digital exhibition and conference (December 1-2), for its LNT-21191-Z4C – a fabric based on post-consumer nylon obtained from tyres.

The tyres are being recycled in a process called ChemCyling developed by BASF. During the conference it was explained that this recycling platform can use both mixed plastic waste from municipal waste collections and discarded automotive tyres. The waste is chemically recycled into a pyrolysis oil which replaces crude fossil oil as a feedstock. The recycled amount is allocated in the product via a certified mass balance approach.

The Long Advance fabric consists of 7% elastane and 93% recycled polyamide, both reducing the need for synthetic fabrics and also ensuring that tyre waste is recycled in a meaningful way.

Drirelease, headquartered in East Brunswick, New Jersey, meanwhile claimed the Performance Days Performance Award for its Dricomfort Geo knitted fabric.

Judges commented that the processing of the various fibres in the knitting process for Dricomfort Geo, in combination with its finishing, makes the reversible interlock fabric – based on 50% recycled polyester, 44% polyester and 6% Lycra – unique.

New pattern and knit designs are possible thanks to a special jacquard knitting process developed by the company and used to process the recycled polyester yarn. The material is said to be light and versatile, and GEO technology also ensures optimal body temperature management. The material provides excellent thermal regulation features through efficient heat management and enhanced moisture transport.
