Drawstring Short Customization Program for Manufacturing Plants with Ultrasonic Welding
Drawstring Short Customization Program for Manufacturing Plants
This programme covers the full path from a drawstring short concept to repeatable bulk supply for manufacturing plants. The build starts from everyday-casual references — drawstring short in fleece-back cotton — then locks fabric weight, wash behaviour and fit tolerance so every reorder matches the approved sample.
Most drawstring short buyers arrive with one of these problems: the fit drifted between sizes, or delivery missed the season drop. The fix is a written spec before bulk: shrinkage allowance, stitch density, colour tolerance and a golden sample kept at the factory.

Quality control
Every bulk lot is compared against the approved sample for shade, hand feel, measurements and wash behaviour. Drawstring Short reorders stay comparable over time because the spec, the lab dip and the golden sample are all on file.
FAQ
How long does sampling take?
A first prototype is typically ready in 12 working days after the tech pack is confirmed, including fabric sourcing if the base cloth is not in our stock library. Revisions add about 3 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.
What file formats do you need for artwork?
Vector files (AI, EPS, PDF) give the best print and embroidery results. For raster artwork please supply at least 300 dpi at the final print size. We digitise embroidery files in-house and return a sew-out photo for approval.
What is the minimum order quantity?
Standard programmes start at 500 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.
