A production-ready Ponte Roma Knit for Swimwear, specified around chlorine and sunscreen resistance with shape retention. Composition is polyester spandex with charcoal loaded filament, which delivers permanent odour adsorption built into the yarn rather than the finish. Every lot is finished and tested so that Compression is measurable rather than claimed.

Why this construction works
Because a firm ponte roma double knit is used, the fabric behaves consistently across the roll: a clean, structured surface with enough hold for tailored athleisure. That consistency is what lets a factory cut confidently and lets a brand repeat an order a season later with the same result.

- Consistency: GSM and width tolerance are locked per lot and recorded on the inspection sheet.
- Durability: performance is verified after repeated washing, not only as delivered.
Recommended applications
Used for Swimwear and for the accessories around them. chlorine and sunscreen resistance with shape retention is the reason it is chosen, and the fabric bonds, prints and sews on standard machinery without special settings.

Compression fabric prepared for Swimwear production
Dyeing, finishing and customisation
The fabric can be supplied greige, piece dyed or printed. Add-on finishes are selected after a wash durability trial, because a finish that disappears after five washes is worse than no claim at all.
Care instructions
- Machine wash at 30 degrees with mild detergent, no fabric softener.
- Dry away from direct heat and do not tumble dry hot.
- Cool iron on the reverse if needed, and avoid bleach.
Ordering, sampling and quality control
Minimum trial order is 300 metres per colour and bulk production takes 20-25 days once the approval sample is signed. Documentation includes test reports per lot, OEKO-TEX conformity and full construction sheets.

Frequently asked questions
Can the weight and width be changed? Yes. Most programmes run between 140 and 340 GSM, and width can be set between 150 and 180 cm to match your marker. Changing weight changes cover and stretch, so we re-test before confirming.
Is the performance tested on every lot? Yes. The named test method is repeated on bulk fabric, not only on the approval sample, and the report carries the lot number so results can be traced back.
