Yarn-Dyed Check Fabric for a School Uniform Buyer in Poland
A School Uniform Buyer approached us with a yarn-dyed check fabric requirement for the Poland 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
- A spec that lived in an email instead of a tech pack
- Shade drift between the approved lab dip and the bulk lot
What we specified
| Item | Yarn-Dyed Check Fabric |
|---|---|
| Client type | A School Uniform Buyer |
| Market | Poland |
| Order volume | 100,000 pieces across 2 specifications |
| Base material | Polyester |
| Standard size | 360 gsm |
| Finish | Sandblasted Finish |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | Bluesign |
How it was resolved
- We rebuilt the specification around Polyester and locked the tolerance before bulk.
- The finish was moved to Enzyme 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
- 100,000 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
