TENCEL™ Lyocell – HV100, the fiber type Lenzing Group introduced at Kingpins Show Amsterdam one year ago, is now running through a network of 11 mills across six countries. That is the headline from Lenzing this week, as the Austria-based fiber producer returns to Amsterdam to show the third iteration of its mill partner collection.

For denim sourcing teams, the significance is straightforward: availability. A specialty fiber confined to a handful of development mills limits who can actually specify it. A wider base of producing mills puts HV100 within reach of cut-and-sew manufacturers and the brands writing the orders — the tier of the supply chain where fabric decisions get locked in.

What is HV100, and what changes for buyers?

TENCEL™ Lyocell is Lenzing's branded lyocell fiber — a cellulosic fiber produced in a closed-loop process that recovers the solvent. The HV100 variant is the new fiber type Lenzing unveiled at the Amsterdam denim show last year.

What's changed in twelve months is scale of adoption. Eleven mills from six countries now work with the fiber, and Lenzing has built its third mill partner collection to prove it out in fabric form. The collection features sample garments showing how the fiber performs and looks in actual production rather than on a spec sheet.

That distinction matters for anyone specifying denim. A sample garment collection built with partner mills signals the fiber has moved past pilot stage into commercially reproducible fabric development — the point where brands can begin sampling against real yardage rather than lab knits.

Who is showing what?

The collection on display at Kingpins this week comes from those 11 partner mills across six countries. Lenzing frames it as a demonstration of accessibility: downstream partners — cut-and-sew manufacturers and brands — can now source HV100-based fabrics from a broader supply base instead of relying on a narrow set of early adopters.

Lenzing is publishing further detail on its Carved in Blue denim blog, its long-running channel for mill and brand profiles around TENCEL-based denim.

The sourcing decision this forces

If you specify lyocell denim, HV100 is now a live option across a multi-mill, multi-country base — which means it belongs in your next round of fabric trialing, not on a watch list.
