Cupro Fabric for a Lingerie Specialist in Vietnam
A Lingerie Specialist approached us with a cupro 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
- Shrinkage that only showed up after the first wash
- Lead time quoted without the plating or dyeing sub-process
- Elastic that lost recovery after three washes
What we specified
| Item | Cupro Fabric |
|---|---|
| Client type | A Lingerie Specialist |
| Market | Vietnam |
| Order volume | 50,000 pieces across 4 specifications |
| Base material | Cotton |
| Standard size | 400 gsm |
| Finish | Yarn-Dyed Finish |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | RoHS |
How it was resolved
- We rebuilt the specification around Cotton and locked the tolerance before bulk.
- The finish was moved to Silicone Wash 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
- 50,000 pieces delivered inside the 10-week window.
- Unit cost held within 3.0% 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
