Developed for Swimwear, this Tricot Warp Knit answers the most common brief we receive: chlorine and sunscreen resistance with shape retention. The yarn package is polyester elastane with a bio-based chitosan finish, chosen because it provides a bio-derived antibacterial route for restricted substance sensitive programmes, and the finished cloth is set and tested so that Cooling Ice-Feel.

Why this construction works
Performance comes from three decisions: the yarn, the stitch and the finishing route. polyester elastane with a bio-based chitosan finish supplies the base behaviour, a warp knitted tricot sets how air and moisture move, and finishing is kept deliberately light so the attributes survive washing.

Performance features
- Cooling Ice-Feel: gives an instant cool touch and spreads heat away from the body, measured by contact cool feeling measurement (Q-max).
- Hand and comfort: a bio-derived antibacterial route for restricted substance sensitive programmes.
- Construction benefit: low curl, smooth and stable, which makes it easy to cut and bond.
- 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
Specified mainly for Swimwear, and suited to any programme where chlorine and sunscreen resistance with shape retention is written into the brief. Designers use the same base for matching styles, which keeps colour continuity simple across a collection.

Dyeing, finishing and customisation
Dyeing runs on a controlled recipe with consolidated dye lots to hold shade continuity. Finishing options include wicking, antibacterial, soft touch and anti-pilling, applied after lab trials so the hand approved in sampling is the hand delivered in bulk.
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
Sampling is fast: A4 hand feel cards, laboratory dips and a 5 metre trial roll within a week. Bulk runs in 20-25 days, with inline inspection and a final random inspection before packing.

Frequently asked questions
Can we get recycled content with this construction? In most cases yes. GRS certified recycled nylon or polyester can replace the virgin yarn with full chain of custody documents, usually with no visible change in hand or performance.
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.
