Case Study: Custom Overlocking Thread for a Car Interior Supplier in the United Arab Emirates

Overlocking Thread for a Car Interior Supplier in the United Arab Emirates

A Car Interior Supplier approached us with a overlocking thread requirement for the the United Arab Emirates 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
• Elastic that lost recovery after three washes
• A spec that lived in an email instead of a tech pack

What we specified

How it was resolved

1. We rebuilt the specification around Neoprene and locked the tolerance before bulk.
2. The finish was moved to Matte Black 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

• 5,000 pieces delivered inside the 6-week window.
• Unit cost held within 3.0% 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.
