Odour Retention Solutions for Swimwear: Care and Service Life Advice
Care instructions decide whether odour retention stays solved for the life of the swimwear, not just until delivery.
What shortens performance
persistent smell after repeated wear even when the garment is clean becomes obvious earlier when the garment is dried hot or washed with softener, because both attack the finish and the elastic. Because the fabric stays wet, stretched and chemically exposed for hours, target checks are made on a worn sample rather than flat fabric alone.
Washing guidance
Wash at 30 degrees inside out with similar colours. Mild detergent preserves the finish applied for odour retention. Keep ISO 20743 and AATCC 100 named in the tech pack so every lot is measured the same way.
Drying and storage
dry flat immediately after training. Where swimwear is worn for pool training and beach use, set tolerances around that range of movement.
Expected service life
With correct care the target of reduction of 99% against Staphylococcus aureus after 10 washes remains approachable for 40-50 home washes, after which routine replacement is reasonable. Any change to nylon and polyester knits at 190-230 GSM with high elastane requires re-testing against reduction of 99% against Staphylococcus aureus after 10 washes before bulk is released.
Supporting the customer
Print clear care wording and mention ISO 20743 and AATCC 100 validation on the product page so claims can be supported if questioned. Past reports from ISO 20743 and AATCC 100 help the mill reproduce the same recipe on the next order.
