Stitch Length How to Read It on a Lab Report
Laboratory reports present Stitch Length in a compact format. Knowing what each line means prevents misreading.
Definition reminder
yarn length consumed per stitch. Working figures for Stitch Length normally sit around 2.6-3.4 mm typical stretch knit in mainstream production. Note machine cam setting on the tech pack so nobody tests against an older revision.
Common report layout
The report states method machine cam setting, sample description, conditioning, and the measured result. Record elastane content alongside Stitch Length, because blends shift the measured value. A result outside 2.6-3.4 mm typical stretch knit usually points to process drift rather than to the fibre itself.
Typical result
Values near 2.6-3.4 mm typical stretch knit usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Stitch Length lets suppliers quote without extra sampling rounds. Ask for conditioning details together with machine cam setting, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Stitch Length normally sit around 2.6-3.4 mm typical stretch knit in mainstream production. Note machine cam setting on the tech pack so nobody tests against an older revision.
Questions to ask
Ask the laboratory for the standard revision and sample description before accepting or rejecting a result. Record elastane content alongside Stitch Length, because blends shift the measured value. A result outside 2.6-3.4 mm typical stretch knit usually points to process drift rather than to the fibre itself.
