Separate the causes
Displaced yarns
Compare relaxed stitched offcuts and unstitched controls; record whether yarns remain continuous around the hole.
Cut or weakened yarns
Examine damage with adequate magnification and retain the needle used; do not infer continuity from a distant photograph.
Equipment interaction
Check burrs, needle condition and machine compatibility with a qualified technician.
Steps before deciding
- Label stitched and unstitched samples from the same roll.
- Record needle system, point, size, thread and speed.
- Trial compatible needle alternatives on the actual layered seam.
- Compare after seam loading and intended care.
- Approve both stitch formation and yarn integrity.
Worked example
Hypothetical case: holes appear only with one worn needle, while a compatible new needle produces intact trial seams. Preserve both trials before making a fabric claim.
Buyer questions
Should all heavy coating use the largest needle?
No. Selection must suit the machine, thread and fabric assembly.
Can I judge damage by hole size alone?
No. Yarn continuity and later seam performance also matter.
