Seven supply-chain partners will spin 10 demonstration fabrics and run five production trials as part of a Fashion for Good-led project benchmarking mechanically recycled cotton yarns against brand quality targets.

The coalition draws together six brands and one quality specialist:

• Arvind
• Bestseller
• C&A
• Interloop
• Reformation
• Shahi
• Uster (spinning quality expert)

The roster mixes vertically integrated textile manufacturers with global brand owners, reflecting the partnership's stated focus on aligning mill capability with retailer specification.

"Recycled cotton has been talked about as a scale-ready solution for years, but the industry has been working from fragmented data and siloed testing," managing director Katrin Ley said. The project is built to close that gap "with hard evidence" by "plotting real recycler capabilities against real brand quality targets," she added.

What are the two parallel workstreams?

The project splits into a benchmarking track and a production track. Track one will map recycler output against brand specifications across both knit and woven categories, producing a Quality Matrix that flags where recycled content matches market expectations and where further investment is needed.

Track two moves into factory-floor testing. Selected recyclers, working with project partners, will spin 10 demonstration fabrics and conduct five trials focused on quality improvement during production. Outcomes feed back into the benchmarking track so the Quality Matrix reflects measured spinning-floor performance, not catalogue claims alone.

What comes out the other end?

Both tracks feed a Trade-off Analysis that weighs recycled content share against cost and quality performance. Findings will be codified into an open-source Standard Operating Procedure (SOP) covering spinning, followed by a public roadmap outlining the data infrastructure needed to scale recycled cotton across product ranges and geographies.

No regulatory mandate sits behind the SOP. The initiative positions it as a voluntary industry reference, leaving brands to reconcile its protocols with whatever recycled-content documentation scheme their procurement and compliance teams already operate under.

Why does the 10% recycled-content ceiling matter?

Cotton accounts for 19% of global fibre production, a share that gives its recycling economics outsized weight in any brand's circularity plan. Mechanical recycling — the dominant commercial route — shreds cotton-rich textile waste into shorter, weaker fibres.

Most commercially usable yarns can carry only around 10% mechanically recycled content before tensile performance erodes, according to figures cited by Fashion for Good. The coalition argues brands should judge recycled blends on a "fit for purpose" basis, rather than benchmark them solely against virgin cotton specifications.

What does this mean for sourcing teams?

Sourcing teams can expect the roadmap and SOP to land with a clear handover to procurement specifying recycled cotton at yarn level. Sourcing managers will need to pressure-test mill claims against the Quality Matrix benchmarks before locking spinner nominations, particularly for knitwear where fibre-length loss hits pilling and tensile recovery hardest.

Brands without dedicated yarn staff will need to verify whether their Tier 2 spinners carry the fibre-testing capability the SOP is built around — the trade-off an open-source standard is designed to clarify.
