Nylon 66 High Tenacity Spandex Four-Way Stretch Recovery Double Knit is a stable double-knit construction developed for Running Tops where low weight with fast moisture transport decides whether a style succeeds. The base is nylon 66 filament with high tenacity spandex, which gives higher melt point and better abrasion resistance for demanding uses. The result is a fabric that delivers Four-Way Stretch Recovery 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. nylon 66 filament with high tenacity spandex supplies the base behaviour, a stable double-knit construction sets how air and moisture move, and finishing is kept deliberately light so the attributes survive washing.

Performance features
- Four-Way Stretch Recovery: extends in both directions and returns without bagging, measured by ASTM D2594 stretch and recovery.
- Hand and comfort: higher melt point and better abrasion resistance for demanding uses.
- Construction benefit: body and firmness without any need for lining.
- 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 Running Tops, and suited to any programme where low weight with fast moisture transport 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.
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.
