Iron Non-Woven Interlining for Underwear — Specification, Uses and Sourcing Notes
Iron Non-Woven Interlining for Underwear: Specification, Uses and Sourcing Notes
Iron Non-Woven Interlining is the version buyers specify for underwear 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 non-woven interlining its strength and surface character. In practice that means the trim behaves differently in cutting, in finishing and in wear: the finish has to be applied before assembly. 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.

- 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.

- Retain a golden sample at the factory and a second one with you.
