80% Nylon 20% Spandex UPF 50+ Sun Protection Interlock Knit combines 80% nylon 6 filament / 20% spandex with a Interlock Knit construction. It is aimed at Yoga Sets that require a soft hand with modest, sustained stretch, and the reason is straightforward: a dry, smooth hand with strong recovery in every direction, so UPF 50+ Sun Protection.

Why this construction works
Performance comes from three decisions: the yarn, the stitch and the finishing route. 80% nylon 6 filament / 20% 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
- UPF 50+ Sun Protection: blocks ultraviolet radiation for outdoor training, measured by AATCC 183 ultraviolet transmittance.
- Hand and comfort: a dry, smooth hand with strong recovery in every direction.
- 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 Yoga Sets, and suited to any programme where a soft hand with modest, sustained stretch 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
Is the performance tested on every lot? Yes. The named test method is repeated on bulk fabric, not only on the approval sample, and the report carries the lot number so results can be traced back.
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.
