Interlock Knit Fabric Sourcing Program for Plus Size Brands: Down Jackets
Interlock Knit Fabric Programme for Plus Size Brands: Down Jackets
This programme covers the full path from a interlock knit fabric requirement to a repeatable bulk supply for plus size brands. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 400 gsm, the finish and the packing, and we hold that specification so every reorder matches the last one. It is built around down jackets, which is where most of the specification detail sits.
The most common failure in interlock knit fabric sourcing is not price — it is drift. A base material changes mill, the shade moves, a plating bath changes and the item quietly stops matching the approved sample. We prevent that with a written spec, an approved counter sample and a golden sample retained at the factory.

What the programme covers
- Specification build from your tech pack or a physical reference sample
- Base material and finish options with costed alternatives
- Sampling, testing and approval against AATCC Test Methods
- Bulk production with in-line inspection and photo reporting
- Packing, documentation and shipment under the agreed Incoterm
Recommended specifications
- Glass — used when strength and abrasion resistance come first
- Nickel Silver — used when strength and abrasion resistance come first
- TPU — selected for colour depth and finish stability
- Ceramic — chosen when the item has to survive repeated laundering

FAQ
How long does sampling take?
14 working days for the first sample, with 3 days per revision round. Plated or dyed-to-match items add a few days.
Do you hold stock for reorders?
Approved specifications are kept on file and, for repeat programmes, base material can be reserved against a rolling forecast.
Can you handle our own artwork or tooling?
Yes. Artwork files or existing tooling can be used; we confirm tolerances in writing before the first production run.
What is the minimum order quantity?
Standard MOQ is 1000 per style per colour. Mixed colourways can be combined on the same spec if the base material is identical.
Send the reference sample or tech pack and we will come back with a costed specification, a sampling timetable and the compliance documents your market requires.
