Mulberry Silk Fabric for a Workwear Distributor in Finland
A Workwear Distributor approached us with a mulberry silk fabric requirement for the Finland 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
- Shrinkage that only showed up after the first wash
- A zipper puller that broke under pull test at the warehouse

What we specified
| Item | Mulberry Silk Fabric |
|---|---|
| Client type | A Workwear Distributor |
| Market | Finland |
| Order volume | 20,000 pieces across 2 specifications |
| Base material | Stainless Steel |
| Standard size | 240 gsm |
| Finish | Silicone Wash Finish |
| Sampling rounds | 2 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | GRS |
How it was resolved
- We rebuilt the specification around Stainless Steel and locked the tolerance before bulk.
- The finish was moved to Rainbow Iridescent 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
- 20,000 pieces delivered inside the 8-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- 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.
