Stretch Denim Fabric for a Denim Manufacturer in Czechia
A Denim Manufacturer approached us with a stretch denim fabric requirement for the Czechia 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
- Shade drift between the approved lab dip and the bulk lot
- Shrinkage that only showed up after the first wash
- A zipper puller that broke under pull test at the warehouse
What we specified
| Item | Stretch Denim Fabric |
|---|---|
| Client type | A Denim Manufacturer |
| Market | Czechia |
| Order volume | 2,000 pieces across 6 specifications |
| Base material | POM Plastic |
| Standard size | 110 gsm |
| Finish | Yarn-Dyed Finish |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | BSCI |
How it was resolved
- We rebuilt the specification around POM Plastic and locked the tolerance before bulk.
- The finish was moved to Powder Coating 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
- 2,000 pieces delivered inside the 6-week window.
- Unit cost held within 1.5% 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.
