Aluminium Two-Way Separating Zipper for Sportswear — Specification, Uses and Sourcing Notes
Aluminium Two-Way Separating Zipper for Sportswear: Specification, Uses and Sourcing Notes
Aluminium Two-Way Separating Zipper is the version buyers specify for sportswear when the base material is fixed by performance rather than by price. This entry sets out what the material actually changes, which specification to write into the tech pack, and where the cost sits — the three questions that decide whether the item passes bulk approval.
What it is
Aluminium gives two-way separating zipper its durability under wash and abrasion. In practice that means the trim behaves differently in cutting, in finishing and in wear: shrinkage allowance has to be built into the spec. Buyers who specify the material up front avoid the most common failure — an item that looks right on the sample card and behaves differently in bulk.

- Colour fastness — tested to GRS on the actual base material, not on a substitute.
- Mechanical performance — abrasion resistance after 10 cycles or washes.
- Compliance — GRS documentation issued with the shipment.
- Consistency — the approved counter sample becomes the reference for every reorder.

How to specify it
- Name the base material in the tech pack, not just the item.
- Fix the size and tolerance in writing before sampling starts.
- Approve a counter sample made from the actual bulk base material.
- Order the test report against the standard your market requires.
- Retain a golden sample at the factory and a second one with you.
