Case Study: Custom Jacket Lining Fabric Interlining Lining for a Security Company in New Zealand

Jacket Lining Fabric Interlining Lining for a Security Company in New Zealand

A Security Company approached us with a jacket lining fabric interlining lining requirement for New Zealand. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive shipping and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.

The challenge

• Inconsistent sizing between production runs
• No reliable way to track a order once it enters production
• Unclear responsibility when a defect shows up after washing

What we specified

How it was resolved

1. We rebuilt the tech pack around Quick-Dry Polyester and locked shrinkage allowance before grading.
2. Decoration was moved to Hangtag and Packaging after strike-off tests showed better wash 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 size ratio specification.

Result

• 800 pieces delivered inside the 5-week window.
• Unit cost held within 3.0% of the original quotation.
• Return rate linked to fit or workmanship stayed under 0.5%.
• The specification is now on file, so reorders reproduce the approved sample.

What we would repeat

Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
