Recycled PET Rib Knit Fabric for Bras — Specification, Uses and Sourcing Notes
Recycled PET Rib Knit Fabric for Bras: Specification, Uses and Sourcing Notes
Recycled PET Rib Knit Fabric is the version buyers specify for bras 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
Recycled PET gives rib knit fabric its weight-to-strength ratio. In practice that means the fabric behaves differently in cutting, in finishing and in wear: tighter tolerance is needed on the finished dimension. 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.
