Developed for Sports Bras, this Rib Knit answers the most common brief we receive: controlled support and soft contact at the underband. The yarn package is 92% GRS recycled polyester / 8% spandex, chosen because it provides bottle-to-fabric traceability with full chain of custody records, and the finished cloth is set and tested so that Four-Way Stretch Recovery.

Why this construction works
Performance comes from three decisions: the yarn, the stitch and the finishing route. 92% GRS recycled polyester / 8% spandex supplies the base behaviour, a rib knit 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: bottle-to-fabric traceability with full chain of custody records.
- Construction benefit: high extension across the width with clean recovery, ideal for cuffs and bands.
- 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
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.
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.
