Separate the causes
Stitch pickup failure
Check whether stitches securely engage the intended folded layers and whether thread remains intact.
Split-depth variation
Compare separation depth along the failed edge with the approved hand-sewn sample.
Fabric binding concern
Inspect whether separation propagates beyond the prepared seam zone; review the construction with the mill.
Steps before deciding
- Label the failed edge, lot and exact garment location.
- Retain an intact edge made by the same operation.
- Record split preparation, folded widths and stitch sequence.
- Trial the actual assembly under agreed opening loads.
- Check both edge appearance and integrity after care.
Worked example
Hypothetical example: thread remains intact but one folded layer pulls free while the fabric binding elsewhere is sound. Investigate stitch pickup before treating this as general double-cloth delamination.
Buyer questions
Can I use deeper stitches?
Trial visibility and integrity together; deeper pickup may show on the face.
Is flat fabric strength enough?
It does not reproduce the split and folded hand-seam.
