Brightplus and Leaf Bio unveil two-layer bio-based performance textile

Brightplus and Leaf Bio are introducing a performance textile concept that removes a separate adhesive layer, cutting a conventional three-layer construction down to two. The material will debut at Performance Days in Munich on Oct. 13-14, 2026, as brands look for simpler constructions with more renewable content.

Why it matters: - Performance textiles often force brands to trade off technical performance, material complexity and sustainability. - The new concept aims to simplify construction while increasing the use of bio-based materials in high-performance fabrics. - The approach could help textile brands reduce fossil-based inputs without giving up durability, function or design flexibility.

What happened: - Brightplus and Leaf Bio combined two bio-based technologies to create a performance fabric without a separate adhesive layer. - The new material concept pairs NovaPolyPEF, a 100% bio-based PEF textile platform, with BrightBio, Brightplus’ bio-based functional lamination technology. - The material will be presented at Performance Days in Munich on Oct. 13-14, 2026. - The concept will be shown in the Innovation Corner, with BrightBio at Booth IN21I and NovaPolyPEF at Booth IN22. - More information

The details: - BrightBio film is laminated directly onto the NovaPolyPEF textile. - The film provides both the functional layer and the bond. - That eliminates the need for a separate adhesive layer. - The result changes a conventional three-layer textile structure into two functional layers. - BrightBio is designed as an alternative to conventional fossil-based functional textile coatings. - BrightBio uses certified renewable raw materials, including non-edible biomass side streams and captured CO₂. - BrightBio is designed as a drop-in technology compatible with existing textile production processes. - The concept keeps functional and aesthetic requirements at the center of the material design. - Leaf Bio develops plant-based advanced materials including FDCA and PEF. - Leaf Bio is the official partner of NovaPoly.

Between the lines: - The partnership is not just swapping one material for another; it is trying to rethink the whole layer stack in performance textiles. - That matters because fewer layers can mean simpler manufacturing, fewer inputs and potentially easier scaling. - The use of renewable feedstocks and captured CO₂ also signals a push to lower dependence on fossil-derived materials. - Milja Hannu-Kuure, CEO of Brightplus, said sustainability should not require compromising performance and that the project shows how complementary material technologies can support the transition.

What's next: - The companies will publicly debut the concept at Performance Days in Munich on Oct. 13-14, 2026. - Textile manufacturers and brands can evaluate the material concept at the event and assess whether it fits existing production lines. - The presentation could set up further development or adoption discussions in technical apparel and other performance textile categories.

The bottom line: - Brightplus and Leaf Bio are betting that a simpler, two-layer bio-based construction can deliver performance textiles with less complexity and more renewable content.
