Core Spun Thread for a Uniform Supplier in Taiwan
A Uniform Supplier approached us with a core spun thread requirement for the Taiwan 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
- Cartons packed to the factory ratio instead of the buyer's size ratio
- Shade drift between the approved lab dip and the bulk lot
- An interlining that bubbled after the first press
What we specified
| Item | Core Spun Thread |
|---|---|
| Client type | A Uniform Supplier |
| Market | Taiwan |
| Order volume | 20,000 pieces across 4 specifications |
| Base material | Silicone |
| Standard size | 25 mm Width |
| Finish | Rose Gold Plating |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around Silicone and locked the tolerance before bulk.
- The finish was moved to Nickel-Free Electroplating 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 6-week window.
- Unit cost held within 3.0% 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.
