Cotton Thread Sourcing Program for Denim Mills: Bras
Cotton Thread Programme for Denim Mills: Bras
This programme covers the full path from a cotton thread requirement to a repeatable bulk supply for denim mills. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 3# Gauge, the finish and the packing, and we hold that specification so every reorder matches the last one. It is built around bras, which is where most of the specification detail sits.
The most common failure in cotton thread 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 Bluesign
- Bulk production with in-line inspection and photo reporting
- Packing, documentation and shipment under the agreed Incoterm
Recommended specifications
- Cotton — best balance of cost, availability and test performance
- Neoprene — used when strength and abrasion resistance come first
- Copper — best balance of cost, availability and test performance
- Stainless Steel — chosen when the item has to survive repeated laundering

FAQ
How long does sampling take?
7 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.
What is the minimum order quantity?
Standard MOQ is 3000 per style per colour. Mixed colourways can be combined on the same spec if the base material is identical.
Can you match a physical sample?
Yes. Send the reference and we reverse engineer the specification, then produce a counter sample for approval before any bulk commitment.
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.
