Custom Sleeve & Knee Sleeve — Spandex Jersey with Ultrasonic Welding
We supply sleeve & knee sleeve to brands, retailers and uniform programmes, made in Spandex Jersey with ultrasonic welding for denim and workwear programmes. On a piece like this the specification that decides whether it sells or comes back is compression profile, which has to be even along the limb — so that is agreed in writing before bulk, not discovered after the shipment lands. Programmes start at 300 pieces per style.
The failures here are predictable: colour drift between the approved sample and the bulk trim, or a finish that tarnishes or rubs off after washing. 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 CPSIA lead and phthalate testing 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 compression profile.
