Polyester Spandex Graphene Filament Thermal Brushed Double Knit combines polyester spandex with graphene modified filament with a Double Knit construction. It is aimed at Leggings that require squat-proof coverage and recovery at the knee and seat, and the reason is straightforward: thermal regulation and far infrared behaviour from the yarn itself, so Thermal Brushed.

Why this construction works
Performance comes from three decisions: the yarn, the stitch and the finishing route. polyester spandex with graphene modified filament 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
- Thermal Brushed: traps warm air while staying light enough for active use, measured by ISO 11092 thermal resistance.
- Hand and comfort: thermal regulation and far infrared behaviour from the yarn itself.
- 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 Leggings, and suited to any programme where squat-proof coverage and recovery at the knee and seat 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.
Can the weight and width be changed? Yes. Most programmes run between 140 and 340 GSM, and width can be set between 150 and 180 cm to match your marker. Changing weight changes cover and stretch, so we re-test before confirming.
