Zinc Alloy Non-Woven Interlining for Home Curtains — Specification, Uses and Sourcing Notes
Zinc Alloy Non-Woven Interlining for Home Curtains: Specification, Uses and Sourcing Notes
Zinc Alloy Non-Woven Interlining is the version buyers specify for home curtains 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 non-woven interlining 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.
