Custom Sleeve & Knee Sleeve — Cotton Yarn with Ultrasonic Welding
We supply sleeve & knee sleeve to brands, retailers and uniform programmes, made in Cotton Yarn with ultrasonic welding for uniform and corporate programmes. On a piece like this the specification that decides whether it sells or comes back is recovery after repeated stretching, because a bagged sleeve is dead — so that is agreed in writing before bulk, not discovered after the shipment lands. Programmes start at 500 pieces per style.
The failures here are predictable: minimum order quantities far above what a growing brand can absorb, or a supplier who disappears once the deposit is paid. We lock material, construction, measurement and tolerance on a pre-production sample, and prepare GB 18401 safety classification with GB/T 29862 fibre labelling so the container clears instead of missing the season it was bought for.

Packing, testing and delivery
Pieces are packed to the ratio you specify — by size, by colour or by style set — with barcodes applied where the channel needs them. Test reports for azo dye-free declaration are prepared for the destination market. We ship to Shanghai or Shenzhen with invoice, packing list and certificate of origin, and keep the approved reference on file so reorders reproduce the same material, the same construction and the same recovery after repeated stretching.
