Cover Stitch Frequently Asked Questions
Short answers to the questions buyers ask most often about Cover Stitch.
What does it mean?
elastic cover stitch for hems. Working figures for Cover Stitch normally sit around two or three needle versions in mainstream production. Note cover stitch machines on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from two or three needle versions and adjust for the end use of the garment. Record elastane content alongside Cover Stitch, because blends shift the measured value. A result outside two or three needle versions usually points to process drift rather than to the fibre itself.
How is it tested?
cover stitch machines. Keeping reference values for Cover Stitch lets suppliers quote without extra sampling rounds. Ask for conditioning details together with cover stitch machines, since both affect the reading.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. Working figures for Cover Stitch normally sit around two or three needle versions in mainstream production. Note cover stitch machines on the tech pack so nobody tests against an older revision.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. Record elastane content alongside Cover Stitch, because blends shift the measured value. A result outside two or three needle versions usually points to process drift rather than to the fibre itself.
