Textile Exchange chief executive Claire Bergkamp has told delegates at the industry body's annual conference in Vancouver that global textile fibre production is growing faster than uptake of preferred materials — and that closing that gap requires firmer demand-side commitments from brands, not just supplier-side progress.

Speaking at the on-going conference in Canada, Bergkamp said industry progress on preferred materials (fibres with lower environmental impact than conventional equivalents, such as organic cotton or recycled polyester) is real but still insufficient to match the growth in global textile fibre production.

"We need more companies coming into the ring with us, making commitments, more people engaged in this work," she said, according to remarks reported from the event.

The intervention matters because Textile Exchange sits at the centre of the standards infrastructure that most major apparel and footwear buyers use to verify their material claims. When its chief executive says demand is the bottleneck, that's a signal aimed squarely at sourcing and sustainability teams at brand level.

What does this change for sourcing teams?

Bergkamp's framing shifts the pressure point from Tier 2 and Tier 3 suppliers (fabric mills and raw material processors) to the brands that set order volumes. Suppliers have shown they can produce certified preferred materials; what they lack is multi-year offtake certainty that justifies capacity investment.

For practitioners, the operational readout is straightforward:

• Volume commitments for preferred materials increasingly need to be long-dated, not annual, if mills are expected to invest.
• Procurement and sustainability functions will need to align material targets with actual order books rather than aspirational pledges.
• Verification through Textile Exchange's standards framework remains the compliance backbone for any preferred-fibre claim.

Where does the new Materials Matter standard fit?

The call for demand certainty comes as Textile Exchange rolls out its Materials Matter standard, the successor framework consolidating its existing material standards. The timing is deliberate: a consolidated standard lowers the administrative cost of participation, but it only moves the market if more companies commit to it.

For brands already certified under legacy Textile Exchange standards, the rollout means migration planning, not reinvention. For those outside the system, Bergkamp's message is that sitting out is now the bigger commercial and reputational exposure.

The decision this forces

The core commercial question Bergkamp has put to the industry is whether brands will convert stated material ambitions into contracted, verifiable demand. Until they do, the gap between fibre production growth and preferred-material uptake will keep widening, and suppliers will keep pricing in that uncertainty.

For sourcing leaders, the actionable step is embedding preferred-material volumes into supplier agreements with the same rigour as price and lead time — because that's the only demand signal that travels all the way down the chain.

The message from Vancouver: the standards exist, the supply base is ready, and the missing input is a firm order.
