Iron Polyester Spandex Fabric for Uniforms — Specification, Uses and Sourcing Notes
Iron Polyester Spandex Fabric for Uniforms: Specification, Uses and Sourcing Notes
Iron Polyester Spandex Fabric is the version buyers specify for uniforms 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 polyester spandex fabric its durability under wash and abrasion. In practice that means the fabric 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.

How to specify it
- Name the base material in the tech pack, not just the item.
