Leading Turkish denim producer ISKO Denim has launched a new range of fabrics that it claims is "its most revolutionary, responsible" to date.

The R-TWO range uses a blend of reused cotton and recycled polyester to reduce the amount of raw material sourced, and is said to improve sourcing efficiency throughout the entire field-to- fabric production. It also tackles over-sourcing – the leading issue when it comes to waste.

During the processing of raw cotton into yarn, for every 100 kilos of cotton approximately 10% is lost. ISKO collects this and prevents it from becoming waste by adding it back into the spinning process, thereby obtaining cotton that is fully traced, documented and audited.

This verification process has been developed by ISKO in partnership with its yarn supplier Sanko, offering full clarity into the traceability of reused cotton from field to fabric. Recycled polyester comes from clear plastic bottles or, alternatively, it can come from other certified waste: in either case the source material is collected, sorted, stripped of labels and caps, and cleaned. This material is then ground into plastic pellets that can then be re-spun into new fibre filaments, which are then blended with the reused cotton to create R-TWO fabrics.

"The R-TWO programme was developed to keep on delivering a futuristic and innovative sustainable approach, one where ISKO rethinks its sourcing strategies and refuses to source more raw materials than what actually needed," the company explains. 

ISKO is one of the world's largest denim producers with a production capacity of 300 million metres of fabric per year and 2,000 high-tech automated looms. It is part of Sanko Tekstil, the textiles division of the Sanko Group, a conglomerate with interests spanning construction and energy, to packaging, financial services, healthcare and education.
