Polyester Fabric for a Uniform Supplier in Vietnam
A Uniform Supplier approached us with a polyester fabric requirement for the Vietnam 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
- An interlining that bubbled after the first press
- A compliance document that arrived after the goods were already shipped
- Shrinkage that only showed up after the first wash
What we specified
| Item | Polyester Fabric |
|---|---|
| Client type | A Uniform Supplier |
| Market | Vietnam |
| Order volume | 10,000 pieces across 3 specifications |
| Base material | Glass |
| Standard size | 140 gsm |
| Finish | Enzyme Wash Finish |
| Sampling rounds | 3 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | JIS L Standards |
How it was resolved
- We rebuilt the specification around Glass and locked the tolerance before bulk.
- The finish was moved to Black Nickel 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
- 10,000 pieces delivered inside the 5-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
