Denim Fabric for an Airline Catering Supplier in China
An Airline Catering Supplier approached us with a denim 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
- Shrinkage that only showed up after the first wash
- Shade drift between the approved lab dip and the bulk lot
- An interlining that bubbled after the first press

What we specified
| Item | Denim Fabric |
|---|---|
| Client type | An Airline Catering Supplier |
| Market | China |
| Order volume | 10,000 pieces across 6 specifications |
| Base material | Bamboo |
| Standard size | 450 gsm |
| Finish | Rainbow Iridescent Finish |
| Sampling rounds | 3 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | California Prop 65 |
How it was resolved
- We rebuilt the specification around Bamboo and locked the tolerance before bulk.
- The finish was moved to UV Printing 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 8-week window.
- Unit cost held within 1.5% 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
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
