Could this ‘fibre-welding’ technology be a game changer for sustainable cycling performance kit?

US biotech manufacturer Natural Fiber Welding claims that its Clarus technology gives a “synthetic-like performance but from 100% natural sources”

Remember when cycling kit was invariably made out of wool? Things could get extremely sweaty, and then everything changed with the introduction of lightweight, synthetic fibres... but an Illinois-based biotech firm could be about to take us back but to the future with its patented Clarus technology, which alters 'virgin' (first time use) and recycled plant fibres like cotton to transform into high-performance materials, providing a more sustainable alternative to synthetics.

The technology, according to Natural Fiber Welding (NFW), drives extensive intermolecular bonding in natural polymers, effectively lengthening and strengthening natural fibres. “It uses ionic liquids to swell, mobilise and then reconstruct cellulosic bonds at the molecular level,” NWF explains.

Clarus is designed to make it possible to manufacture performance apparel with recycled and virgin natural fibres: “By retaining the all-natural polymeric properties of the input fibres, what starts as circular by nature can end as circular by nature.”

“When Clarus returns strength and tenacity to recycled fibres, resource demands for virgin fibres are reduced,” reads the Clarus website. 

“Our closed-loop chemistry process enables naturally plentiful materials – like cotton, hemp, and wool – to take new shapes and perform at new levels.

“This means synthetic-like performance but from 100% natural sources.”

Clarus is claimed to be 'game-changing' for its sweat-wicking qualities, with NFW saying: "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”,

NFW also claims Clarus is “a moisture management breakthrough to rival synthetics”. 

The improved strength achieved through fibre-welding is said to increase the garment lifespan: “The Clarus platform drives extensive hydrogen bonding between natural fibres, resulting in performance-ready yarns and fabrics resistant to fraying, piling and abrasion damage.” 

Ralph Lauren is the first clothing brand to bring a product to market using the technology, with the RLS Clarus Polo Shirt debuting at the 2022 Australian Open Tennis Tournament. Californian outerwear company Patogonia, which is very well-regarded for its sustainability initiatives, has also partnered with NFW.

This is a startup in my current home town. I have several friends who work there. I really hope it takes off.

I only wear merino wool jerseys and bib shorts now. Far better body climate than synthetics. Warm when the weather is cold, yet not hot when it's warm. Doesn't stink like lycra stuff and lasts longer than lycra that is worn out after two seasons.

Sounds great, but also expensive. As it's patented I suspect that it'll only be used in top-end clothing - will probably wait for the patent to expire and then buy it cheap in Aldi.

goretex holds patents but licenses its use....a patent in itself doesn't prevent others from using/buying the material. 

through the techno babble its good to see more appraoches to resusing clothing fibres and creating a more sustainable circular economy.

Yes, although it depends on the whims of the patent owner. Gore-Tex is mainly used in high-end equipment, so I'd guess this fabric will be similar.
