Case Study: Custom Polyester Fabric for a Denim Manufacturer in South Africa

Polyester Fabric for a Denim Manufacturer in South Africa

A Denim Manufacturer approached us with a polyester fabric requirement for the South Africa 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
• A spec that lived in an email instead of a tech pack
• MOQ that was quoted per colourway rather than per style

What we specified

How it was resolved

1. We rebuilt the specification around Silicone and locked the tolerance before bulk.
2. The finish was moved to Powder Coating 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

• 100,000 pieces delivered inside the 8-week window.
• Unit cost held within 2.0% of the original quotation.
• Inspection-related rejection stayed under 1.5%.
• The specification is now on file, so reorders reproduce the approved sample.

What we would repeat

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
