Case Study: Custom Core Spun Thread for a Uniform Supplier in France

Core Spun Thread for a Uniform Supplier in France

A Uniform Supplier approached us with a core spun thread requirement for the France 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
• Cartons packed to the factory ratio instead of the buyer's size ratio
• Reorders that quietly changed supplier and changed the hand feel

What we specified

How it was resolved

1. We rebuilt the specification around Bamboo and locked the tolerance before bulk.
2. The finish was moved to Antique Brass Plating after strike-off tests showed better durability.
3. A pre-production sample was approved and retained as the golden reference.
4. Production ran with in-line inspection and a mid-run photo report.
5. Cartons were packed to the client's own barcode and ratio specification.

Result

• 10,000 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

Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
