Custom Sewing Thread in Slub Cotton with Ultrasonic Welding

Custom Sewing Thread — Slub Cotton with Ultrasonic Welding

We build sewing thread programmes from a tech pack or a physical reference sample. This Slub Cotton version is developed for brands that need a repeatable specification: the same cloth, the same hand feel and the same fit on every reorder. Fabric, trims, ultrasonic welding and packaging are all specifiable, so the garment stays consistent across seasons and across production runs.

Most buyers come to us after one of these problems: minimum order quantities far above what a growing brand can absorb, or inconsistent sizing between production runs. Our response is to fix the specification first — fabric weight, shrinkage allowance, stitch density and tolerance — before a single bulk metre is cut.

Quality control

Every bulk order is checked against the approved sample for shade, hand feel, measurements and workmanship. We record shrinkage, colour fastness and seam strength on the first bulk lot and hold the data as the reference for reorders, so sewing thread batches stay comparable over time. Inspection photos and the measurement report are sent before the balance payment is due.

FAQ

How long does sampling take?

A first prototype is typically ready in 10 working days after the tech pack is confirmed, including fabric sourcing if the base cloth is not in our stock library. Revisions add about 5 days each.

How is shipping handled?

We quote EXW, FOB, CIF and DDP. Consolidated sea freight is the default for bulk programmes, with air or express options when a launch date is at risk.

Can you match a specific colour?

Yes. Send us a Pantone TCX reference or a physical swatch. We return lab dips for approval and hold bulk shade within the agreed tolerance band before cutting.

What is the minimum order quantity?

Standard programmes start at 100 pieces per style and colour. We can split sizes across a size set, and for first orders we often accept a mixed-colour run to help you test the market.
