Custom Zipper in Polypropylene (PP) with Piece Dyeing for Uniform and Corporate Programmes

Custom Zipper — Polypropylene (PP) with Piece Dyeing

We supply zipper to garment factories and brands, built in Polypropylene (PP) with piece dyeing for e-commerce and small-batch brands. On a trim like this the specification that decides the outcome is tape shrinkage matched to the garment fabric, 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: minimum order quantities far above what a growing brand can absorb, or packing that arrives mixed and unusable on the line. We lock material, finish, dimension and tolerance before bulk, and prepare GB 18401 safety classification with GB/T 29862 fibre labelling so the shipment clears instead of sitting at port while your selling season passes.

How we produce it

1. Drawing or reference sample review, with size and finish confirmed
2. Material selection and a finish sample or strike-off
3. Prototype made to the agreed gauge
4. Fit and wash test on the actual garment fabric, then a pre-production sample
5. Bulk run with piece dyeing applied under controlled settings
6. 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 GRS recycled content claim are prepared for the destination market. We ship to Shanghai or Shenzhen 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 tape shrinkage matched to the garment fabric.
