Spandex Fabric for a Sportswear Brand in Portugal
A Sportswear Brand approached us with a spandex fabric requirement for the Portugal market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- A zipper puller that broke under pull test at the warehouse
- An interlining that bubbled after the first press
- MOQ that was quoted per colourway rather than per style
What we specified
| Item | Spandex Fabric |
|---|---|
| Client type | A Sportswear Brand |
| Market | Portugal |
| Order volume | 5,000 pieces across 6 specifications |
| Base material | Polyester |
| Standard size | 110 gsm |
| Finish | Matte Black Coating |
| Sampling rounds | 3 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | GB 18401 |
How it was resolved
- We rebuilt the specification around Polyester and locked the tolerance before bulk.
- The finish was moved to Sandblasted Finish after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
Result
- 5,000 pieces delivered inside the 5-week window.
- Unit cost held within 2.0% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
