The technology

Polygiene StayFresh™‎

Polygiene StayFresh™‎ — antibacterial textile freshness technology, applied by INATURAL.

Polygiene StayFresh™‎ is designed to help textiles stay fresher between washes by inhibiting the growth of odour-causing bacteria on the textile — for garments, towels, uniforms, sportswear, medical and home textiles where freshness between washes matters.

Freshness that starts in the fibre.

How it works

How StayFresh works

Odour often begins when bacteria multiply on textile surfaces after contact with sweat, humidity, or daily use. Polygiene StayFresh™‎ works at the material level to inhibit the growth of odour-causing bacteria — helping the textile stay fresh without relying on perfume or temporary masking.

Because the treatment is integrated into the textile, freshness becomes part of the product — designed to help fabrics stay fresher and comfortable through repeated use and laundering, depending on textile type, application route and test requirements.

Without treatment
Bacteria multiply after contact with sweat and moisture
Odour builds up and returns quickly
Odour can send textiles to the wash early
With Polygiene StayFresh™‎
Bacterial growth inhibited at the fibre
Odour formation reduced, not masked
Fresher for longer between washes
Benefits

Benefits of Polygiene StayFresh™‎

Helps reduce odour formation

Designed to inhibit the growth of odour-causing bacteria on the textile, which produce stale smells.

Fresher between washes

Even with sweat, humidity or repeated use, treated textiles are designed to stay fresher between washes.

Wash when needed

If a textile still smells fresh, it can be used again before washing — where its care label and hygiene rules allow.

Longer use, with good care

Washing when needed and caring for the fibres can help a textile stay in use for longer.

Responsible use

Wash when needed.

When a textile stays fresher between uses, it can be washed when it needs it rather than by habit — within its care label and any hygiene rules. With gentle care, that is intended to help textiles stay in use for longer. It is an intended pathway, not a measured saving: we have not measured water, energy or detergent use. We set out step by step the four-step care cycle that washing when needed depends on.

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 StayFresh across sports towels, training textiles, uniforms and selected performance apparel, with technology selection and validation defined for the intended use.

FAQ

Questions, answered.

It helps inhibit odour-causing bacteria within the textile, reducing odour formation at the source instead of covering it with fragrance.

Yes. It suits towels, sportswear, medical uniforms, hospitality uniforms, workwear, and other categories where freshness between washes matters.

It is designed to help textiles stay fresher between uses, so they can be washed when needed rather than by habit — within the care label and any hygiene rules. We have not measured washing frequency.

Yes. StayFresh can be combined with odour-control technology (OdorCrunch); StayCool is still in development.

The only laboratory evidence INATURAL holds reaches 20 wash cycles, on its own white towel samples, measured in January 2023 against a single bacterial species. It is published in full, with its scope, on the Proof and testing page. For any other textile the answer depends on the fibre, the application route and how the textile is laundered, and it is established on samples of your own fabric before production — we do not carry a figure across from one product to another.

INATURAL publishes its own laboratory evidence in full on the Proof and testing page: one independent report dated January 2023, on INATURAL white towel samples, shown with its method, the single bacterial species it covers, and the fact that the two-year validity stated in it ended in January 2025. The technology descriptions themselves are Polygiene’s. Technical documentation and sample evaluation for your own textile are agreed case by case.
