PU Leather Sewing Thread for Dresses — Specification, Uses and Sourcing Notes
PU Leather Sewing Thread for Dresses: Specification, Uses and Sourcing Notes
PU Leather Sewing Thread is the version buyers specify for dresses 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
PU Leather gives sewing thread its drape and hand feel. 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.

Properties that matter in buying

- Mechanical performance — abrasion resistance after 50 cycles or washes.
