The technology

Polygiene OdorCrunch™‎

Polygiene OdorCrunch™‎ — odour-control textile technology, applied by INATURAL.

Polygiene OdorCrunch™‎ helps textiles resist lingering odours by capturing and neutralising odour molecules on fabric. It targets body odours as well as environmental odours such as cooking fumes, smoke and daily-use smells — helping textiles stay fresher between washes.

Odour control at the molecular level.

How it works

How OdorCrunch works

Odour molecules from sweat, food, smoke, and the surrounding environment can become trapped in textile fibres. Polygiene OdorCrunch™‎ uses silica-based odour-control technology to attract, capture and reduce the impact of those odour molecules on the fabric.

The aim is a textile that stays fresher between uses and can be washed when it needs it — especially useful for sportswear, towels, uniforms, hospitality textiles, home textiles, upholstery, curtains, and other hard-to-launder applications.

Without treatment

Fresher for longer, even between washes
Benefits

Benefits of Polygiene OdorCrunch™‎

Captures body odours

Helps reduce unpleasant smells caused by sweat and repeated use.

Neutralises environmental odours

Targets lingering odours from cooking fumes, smoke and surrounding environments.

Wash when needed

By reducing odour build-up, textiles are designed to stay usable for longer between washes.

Evaluated on your textile

How long odour control lasts depends on the textile, the application and care, and is evaluated on samples before production.

These descriptions of what Polygiene OdorCrunch™‎ does are Polygiene’s, as the technology’s supplier. INATURAL has not measured odour performance on its own products: the one independent laboratory report it holds is antibacterial, carried out in January 2023 on white towel samples against a single bacterial species, and the validity period stated in it has ended. No odour figure is borrowed from another product to fill that gap.

Applications

Great for hard-to-wash textiles

Especially valuable where fabrics cannot be washed after every use — from upholstery to hospitality textiles.

Responsible use

Fewer odour-driven washes.

Odour is often the reason a textile goes into the wash before it is really dirty. By helping fabrics stay fresher between uses, Polygiene OdorCrunch™‎ is designed to support washing when needed — especially for textiles that are hard to wash after every use. With good care, that can help textiles stay in use for longer. We have not measured water, energy, detergent or microfibre savings, so we do not claim them.

For professional programmes

Built for professional programmes

INATURAL works with clubs, academies, teamwear partners and performance-focused organisations to develop textile solutions around real operational needs — from odour management and freshness to thermal comfort and product durability.

Custom programmes can apply OdorCrunch across sports towels, training textiles, uniforms and selected performance apparel, with technology selection and validation defined for the intended use.

FAQ

Questions, answered.

It uses silica-based technology to capture and reduce odour molecules that cling to textile fibres.

It can help reduce body odours and environmental odours such as cooking smells, smoke, and other lingering fabric odours.

No. It is also useful for towels, upholstery, curtains, hospitality textiles, uniforms, and other hard-to-wash applications.

Yes. StayFresh targets odour-causing bacteria, while OdorCrunch captures odour molecules. The right combination depends on the textile and how it is used.

It is designed to support washing when needed: a textile that stays fresher between uses can be washed when it needs it rather than by habit, within its care label and hygiene rules. That is an intended pathway, not a measured saving — we have not measured water, energy or detergent use.
