Nylon Spandex Silver Ion Yarn UPF 50+ Sun Protection Interlock Knit combines nylon spandex with silver ion filament 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: antibacterial performance that survives repeated home laundering, so UPF 50+ Sun Protection.

Why this construction works
The construction does the work before any chemistry is added. a double-bed interlock knit means identical faces on both sides, so the fabric stays opaque under tension, and that structure is what allows the fabric to blocks ultraviolet radiation for outdoor training under the conditions Yoga Sets actually face.

Performance features
- UPF 50+ Sun Protection: blocks ultraviolet radiation for outdoor training, measured by AATCC 183 ultraviolet transmittance.
- Hand and comfort: antibacterial performance that survives repeated home laundering.
- 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
The first choice for Yoga Sets, where a soft hand with modest, sustained stretch is the requirement that decides the fabric. It also converts cleanly into coordinated pieces in the same programme, since the hand and the shade run together.

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.
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.
