TPU Polyester Spandex Fabric — Specification, Uses and Sourcing Notes
TPU Polyester Spandex Fabric: Specification, Uses and Sourcing Notes
TPU Polyester Spandex Fabric is the version buyers specify 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 polyester spandex fabric its strength and surface character. 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.

Typical specification
| Item | Polyester Spandex Fabric |
|---|---|
| Base material | TPU |
| Standard size | 450 gsm |
| Common finishes | Antique Brass Plating, Yarn-Dyed Finish, Brushed Silver Finish |
| Processes | Enamel Filling, Anti-Bacterial Finishing, Digital Printing |
| Typical applications | Jeans, Yoga Wear, Lingerie, Skirts |
| Test standard | RoHS |
| Usual packing | 200 pieces per polybag, 2000 per carton |
Properties that matter in buying
- Dimensional stability — 3% allowance is built into the spec before cutting.
- Colour fastness — tested to RoHS on the actual base material, not on a substitute.
- Mechanical performance — pull strength after 50 cycles or washes.
- Compliance — RoHS documentation issued with the shipment.
- Consistency — the approved counter sample becomes the reference for every reorder.

Common uses
- Kidswear
- Bras
- Evening Wear
- Trousers
- Sneakers
- Scarves
How to specify it
- Name the base material in the tech pack, not just the item.
- Fix the size and tolerance in writing before sampling starts.
- Approve a counter sample made from the actual bulk base material.
- Order the test report against the standard your market requires.
- Retain a golden sample at the factory and a second one with you.
