Skewing and Spirality How to Read It on a Lab Report
Laboratory reports present Skewing and Spirality in a compact format. Knowing what each line means prevents misreading.
Definition reminder
twisting of the knitted loop structure. Working figures for Skewing and Spirality normally sit around below 3% displacement in mainstream production. Note AATCC 179 skewness on the tech pack so nobody tests against an older revision.
Common report layout
The report states method AATCC 179 skewness, sample description, conditioning, and the measured result. Record elastane content alongside Skewing and Spirality, because blends shift the measured value. A result outside below 3% displacement usually points to process drift rather than to the fibre itself.
Typical result
Values near below 3% displacement usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Skewing and Spirality lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 179 skewness, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Skewing and Spirality normally sit around below 3% displacement in mainstream production. Note AATCC 179 skewness 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 Skewing and Spirality, because blends shift the measured value. A result outside below 3% displacement usually points to process drift rather than to the fibre itself.
