Polyester Fabric for a Lingerie Specialist in China
A Lingerie Specialist approached us with a polyester fabric requirement for the China 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
- Lead time quoted without the plating or dyeing sub-process
- Shade drift between the approved lab dip and the bulk lot
- Elastic that lost recovery after three washes
What we specified
| Item | Polyester Fabric |
|---|---|
| Client type | A Lingerie Specialist |
| Market | China |
| Order volume | 10,000 pieces across 4 specifications |
| Base material | Iron |
| Standard size | 80 gsm |
| Finish | Sandblasted Finish |
| Sampling rounds | 3 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | BSCI |
How it was resolved
- We rebuilt the specification around Iron and locked the tolerance before bulk.
- The finish was moved to Yarn-Dyed 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 4-week window.
- Unit cost held within 4.5% 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.

Tell us the item, the quantity and the delivery window. We will quote it with the sub-processes named, so the lead time you approve is the lead time you get.
