Developed for Sports Bras, this Interlock Knit answers the most common brief we receive: controlled support and soft contact at the underband. The yarn package is 90% polyester filament / 10% spandex, chosen because it provides stable dimensions and easy care at a competitive price, and the finished cloth is set and tested so that Compression.

Why this construction works
Performance comes from three decisions: the yarn, the stitch and the finishing route. 90% polyester filament / 10% spandex supplies the base behaviour, a double-bed interlock knit sets how air and moisture move, and finishing is kept deliberately light so the attributes survive washing.

Performance features
- Compression: delivers graduated support while remaining easy to put on, measured by ASTM D2594 stretch and recovery.
- Hand and comfort: stable dimensions and easy care at a competitive price.
- 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
Specified mainly for Sports Bras, and suited to any programme where controlled support and soft contact at the underband 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
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.
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.
