Nylon Polyester Spandex Tri-Blend Antibacterial Anti-Odor Interlock Knit is a double-bed interlock knit developed for Swimwear where chlorine and sunscreen resistance with shape retention decides whether a style succeeds. The base is 55% nylon / 35% polyester / 10% spandex, which gives a cost-balanced hand with better abrasion life than straight nylon. The result is a fabric that delivers Antibacterial Anti-Odor in daily use rather than only in a laboratory.

Why this construction works
Performance comes from three decisions: the yarn, the stitch and the finishing route. 55% nylon / 35% polyester / 10% spandex supplies the base behaviour, a double-bed interlock knit sets how air and moisture move, and finishing is kept deliberately light so the attributes survive washing.

Performance features
- Antibacterial Anti-Odor: stops the bacteria that turn sweat into odour, measured by ISO 20743 antibacterial test.
- Hand and comfort: a cost-balanced hand with better abrasion life than straight nylon.
- Construction benefit: identical faces on both sides, so the fabric stays opaque under tension.
- 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
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.
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.
