Nylon Spandex Silver Ion Yarn Compression Seamless Circular Knit is a seamless circular knit developed for Swimwear where chlorine and sunscreen resistance with shape retention decides whether a style succeeds. The base is nylon spandex with silver ion filament, which gives antibacterial performance that survives repeated home laundering. The result is a fabric that delivers Compression in daily use rather than only in a laboratory.

Why this construction works
The construction does the work before any chemistry is added. a seamless circular knit means tubular production that removes the side seam entirely, and that structure is what allows the fabric to delivers graduated support while remaining easy to put on under the conditions Swimwear actually face.

Performance features
- Compression: delivers graduated support while remaining easy to put on, measured by ASTM D2594 stretch and recovery.
- Hand and comfort: antibacterial performance that survives repeated home laundering.
- Construction benefit: tubular production that removes the side seam entirely.
- 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
The first choice for Swimwear, where chlorine and sunscreen resistance with shape retention is the requirement that decides the fabric. It also converts cleanly into coordinated pieces in the same programme, since the hand and the shade run together.

Compression fabric prepared for Swimwear production
Dyeing, finishing and customisation
Available in piece dyed, yarn dyed or sublimation ready form. Functional finishes such as moisture management, antibacterial, anti-pilling and UV absorption can be applied individually or combined, and each is verified against its test method before bulk release.
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
Trial quantity starts at 300 metres per colour with laboratory dips in five working days. Bulk lead time is 20-25 days after approval, and every lot ships with a test report, a shade check and an inspection record.

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.
