TPU Sewing Thread for Lingerie — Specification, Uses and Sourcing Notes
TPU Sewing Thread for Lingerie: Specification, Uses and Sourcing Notes
TPU Sewing 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
TPU gives sewing thread its weight-to-strength ratio. 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.
