The secret to your success is in our science.

Natural Fiber Welding's patented CLARUS® platform solves the key performance and manufacturing limitation of natural fibers – their physical format.

Using green-chemistry principles and closed-loop processes we engineer performance textiles from virgin and recycled natural fibers.

We built the CLARUS technology platform on the science of “‘welding’” fibers. CLARUS drives extensive intermolecular bonding in natural polymers, effectively lengthening and strengthening natural fibers.

Raw Cotton

Microscopic cross-sectional view of cotton yarn before CLARUS fiber welding: The structure of traditional spun (cotton) staple fiber yarns equates to poor moisture management and slow drying.

Comprehensive Circularity garment-lifespan

Deliver on your sustainability goals with CLARUS. CLARUS makes it possible to manufacture performance apparel with recycled and virgin natural fibers. By retaining the all-natural polymeric properties of the input fibers, what starts as circular by nature can end as circular by nature. The CLARUS technology and resulting products are 100% compatible with future chemical recycling technology that use cellulosic feedstocks. It’s a 360 improvement for your brand, your customers, and the world.

Moisture Management moisture-management

CLARUS changes the game for sweat-wicking with natural textiles. By using hydrogen bonding networks to change the form factor and shape of natural yarns, CLARUS improves the way natural materials absorb, transport, and evaporate moisture — a moisture management breakthrough to rival synthetics. For the first time ever, brands can create all natural, quick-drying apparel.

Improved Strength and Lifespan improved-strength

The CLARUS platform drives extensive hydrogen bonding between natural fibers, resulting in performance-ready yarns and fabrics resistant to fraying, pilling, and abrasion damage. With CLARUS behind your brand, your customers can trust your products are designed to last.
