Custom Sewing Thread — Genuine Leather with Ultrasonic Welding
We supply sewing thread to garment factories and brands, built in Genuine Leather with ultrasonic welding for outerwear and jacket programmes. On a trim like this the specification that decides the outcome is tenacity and elongation, which set the stitch strength, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 1000 pieces per style per finish.
The failures here are predictable: unclear responsibility when a defect shows up after washing, or minimum order quantities far above what a growing brand can absorb. We lock material, finish, dimension and tolerance before bulk, and prepare UKCA and REACH documentation so the shipment clears instead of sitting at port while your selling season passes.

Where it is used
- Denim and workwear — hard-wearing finishes that survive industrial washing
- Outerwear and tailoring — matched to the shell fabric so it drapes with the garment

- Bridal and eveningwear — small runs with hand-finished detail
- Uniform and corporate programmes — repeatable spec held on file for reorders
Packing, testing and delivery
Trims are packed to the ratio you specify — by size, by colour or by garment set — with barcodes applied where the line needs them. Test reports for REACH nickel-release test for metal findings are prepared for the destination market. We ship to Felixstowe with the commercial invoice, packing list and certificate of origin, and hold the approved reference so reorders reproduce the same material, the same finish and the same tenacity and elongation.
FAQ
Can you match a reference sample?
Yes. Send the trim and we match material, finish and shade, then confirm on a pre-production sample before bulk.
How do you control colour on reorders?
The approved reference and the bulk standard are retained, and every reorder is checked against them before shipment.
Do you ship to our forwarder?
Yes. We deliver to your nominated forwarder or quote landed cost under the agreed Incoterm.
What is the minimum order?
Programmes start at 1000 pieces per style per finish. Mixed sizes are fine within one style.
