Yarn-Dyed Check Fabric for a Bag and Luggage Maker in Switzerland
A Bag and Luggage Maker approached us with a yarn-dyed check fabric requirement for the Switzerland 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
- A zipper puller that broke under pull test at the warehouse
- Reorders that quietly changed supplier and changed the hand feel
What we specified
| Item | Yarn-Dyed Check Fabric |
|---|---|
| Client type | A Bag and Luggage Maker |
| Market | Switzerland |
| Order volume | 100,000 pieces across 3 specifications |
| Base material | Glass |
| Standard size | 400 gsm |
| Finish | Rainbow Iridescent Finish |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | AATCC Test Methods |
How it was resolved
- We rebuilt the specification around Glass and locked the tolerance before bulk.
- The finish was moved to Rose Gold Plating 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 8-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- 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.
