Zinc Alloy Overlocking Thread for Shirts — Specification, Uses and Sourcing Notes
Zinc Alloy Overlocking Thread for Shirts: Specification, Uses and Sourcing Notes
Zinc Alloy Overlocking Thread is the version buyers specify for shirts 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
Zinc Alloy gives overlocking thread its drape and hand feel. In practice that means the trim behaves differently in cutting, in finishing and in wear: plating and coating adhesion must be tested on the actual base. 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.
Typical specification

|---|---|
| Base material | Zinc Alloy |

| Usual packing | 200 pieces per polybag, 10000 per carton |
Properties that matter in buying
- Dimensional stability — 3% allowance is built into the spec before cutting.
- Colour fastness — tested to ISO 9001 on the actual base material, not on a substitute.
- Mechanical performance — abrasion resistance after 10 cycles or washes.
- Compliance — ISO 9001 documentation issued with the shipment.
- Consistency — the approved counter sample becomes the reference for every reorder.
Common uses
- Coats
- Footwear
- Blazers
- Sleepwear
- Trousers
- Bedding Sets
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.
