Bonding fails slowly, then all at once

A bonded seam that passes a pull test on day one can delaminate after ten washes if the adhesive, temperature or dwell time drifts. Bonding parameters are set per fabric and logged per lot, and finished pieces go through wash-cycle and peel-strength checks before shipment. Circular-knit bodies are checked for course distortion after laundering, which is where cheap seamless programmes show up as a twisted leg opening. Sizes run XS to 4XL, with cup construction available on seamless bras.

How an order runs

1. 1
   Brief — send sketches, a tech pack, reference samples or product images. We quote and confirm MOQ per style.
2. 2
   Sampling — fitting sample, size-set samples, photo samples and PP samples in about 7 days. Salesman samples take 2–3 weeks.
3. 3
   Revision — samples are revised on your feedback until approved. Sampling and bulk production run on the same technical system, so the approved fit carries into production.
4. 4
   Bulk production — 60–90 days after materials and approvals are confirmed. Fabric and trim lead times are quoted up front.
5. 5
   Inspection — international AQL standard in-house, with third-party inspection supported on request.
6. 6
   Export — export documentation and shipping arranged; custom packaging and private-label trims handled before dispatch.
