Polyester Spandex Graphene Filament Four-Way Stretch Recovery Interlock Knit is a double-bed interlock knit developed for Running Tops where low weight with fast moisture transport decides whether a style succeeds. The base is polyester spandex with graphene modified filament, which gives thermal regulation and far infrared behaviour from the yarn itself. The result is a fabric that delivers Four-Way Stretch Recovery in daily use rather than only in a laboratory.

Why this construction works
Because a double-bed interlock knit is used, the fabric behaves consistently across the roll: identical faces on both sides, so the fabric stays opaque under tension. 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
- Four-Way Stretch Recovery: extends in both directions and returns without bagging, measured by ASTM D2594 stretch and recovery.
- Hand and comfort: thermal regulation and far infrared behaviour from the yarn itself.
- 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
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
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.
What is the minimum for a first order? Development starts at 300 metres per colour, which is enough for a proper wear trial and a small capsule. Bulk pricing improves at 1,000 metres and above per colour.
