Interlock Knit Fabric Sourcing Program for Swimwear Brands: Trousers
Interlock Knit Fabric Programme for Swimwear Brands: Trousers
This programme covers the full path from a interlock knit fabric requirement to a repeatable bulk supply for swimwear brands. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 450 gsm, the finish and the packing, and we hold that specification so every reorder matches the last one. It is built around trousers, 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 California Prop 65
- Bulk production with in-line inspection and photo reporting
- Packing, documentation and shipment under the agreed Incoterm
Recommended specifications
- POM Plastic — used when strength and abrasion resistance come first
- PU Leather — selected for colour depth and finish stability
- Copper — chosen when the item has to survive repeated laundering
- Bamboo — selected for colour depth and finish stability

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.
What are the payment and delivery terms?
Standard terms are a deposit with the order and the balance before shipment, under EXW / FOB / CIF / DDP as agreed.
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 happens if a bulk lot fails inspection?
The lot is reworked or remade at our cost. Inspection reports are shared before the balance payment is due.
Share the programme details and we will propose two alternatives — one optimised for unit cost, one for lead time — and let you choose.
