Custom Sewing Thread — TPU with Injection Moulding
We supply sewing thread to garment factories and brands, built in TPU with injection moulding for childrenswear and schoolwear. 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 inconsistent sizing between production runs. We lock material, finish, dimension and tolerance before bulk, and prepare REACH and GPSR documentation so the shipment clears instead of sitting at port while your selling season passes.

How we produce it
- Drawing or reference sample review, with size and finish confirmed
- Material selection and a finish sample or strike-off
- Prototype made to the agreed count
- Fit and wash test on the actual garment fabric, then a pre-production sample
- Bulk run with injection moulding applied under controlled settings
- In-line inspection, final AQL 2.5 inspection and packing to your ratio
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
- Childrenswear and schoolwear — tested to the destination's safety standard
- 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 azo dye-free declaration are prepared for the destination market. We ship to Rotterdam or 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
Which compliance documents do you provide?
We prepare azo dye-free declaration and the supporting test reports for the destination market.
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.
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 long does sampling take?
A first sample takes 14 working days, and each revision about 3 days.
