TPU Silk Fabric for Sportswear — Specification, Uses and Sourcing Notes
TPU Silk Fabric for Sportswear: Specification, Uses and Sourcing Notes
TPU Silk Fabric is the version buyers specify for sportswear 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 silk fabric its strength and surface character. In practice that means the fabric 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.

Typical specification
| Item | Silk Fabric |

| Base material | TPU |

Properties that matter in buying
- Dimensional stability — 3% allowance is built into the spec before cutting.
- Colour fastness — tested to ISO 9001 on the actual base material, not on a substitute.
- Mechanical performance — elastic recovery after 50 cycles or washes.
- Compliance — ISO 9001 documentation issued with the shipment.
- Consistency — the approved counter sample becomes the reference for every reorder.

Common uses

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.
