A production-ready Seamless Circular Knit for Running Tops, specified around low weight with fast moisture transport. Composition is polyester spandex with graphene modified filament, which delivers thermal regulation and far infrared behaviour from the yarn itself. Every lot is finished and tested so that Antibacterial Anti-Odor is measurable rather than claimed.

Why this construction works
Because a seamless circular knit is used, the fabric behaves consistently across the roll: tubular production that removes the side seam entirely. That consistency is what lets a factory cut confidently and lets a brand repeat an order a season later with the same result.

Performance features
- Antibacterial Anti-Odor: stops the bacteria that turn sweat into odour, measured by ISO 20743 antibacterial test.
- Hand and comfort: thermal regulation and far infrared behaviour from the yarn itself.
- 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
Used for Running Tops and for the accessories around them. low weight with fast moisture transport is the reason it is chosen, and the fabric bonds, prints and sews on standard machinery without special settings.

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
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.
