Iron Overlocking Thread for Lingerie — Specification, Uses and Sourcing Notes
Iron Overlocking Thread for Lingerie: Specification, Uses and Sourcing Notes
Iron Overlocking Thread is the version buyers specify for lingerie 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
Iron gives overlocking thread its strength and surface character. 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.
Typical specification

Properties that matter in buying
- Dimensional stability — 2% allowance is built into the spec before cutting.
- Colour fastness — tested to OEKO-TEX Standard 100 on the actual base material, not on a substitute.
- Mechanical performance — elastic recovery after 20 cycles or washes.
- Compliance — OEKO-TEX Standard 100 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.

- 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.
