Skewing and Spirality What Improves It and What Damages It
Practical actions that raise or lower Skewing and Spirality during knitting, dyeing, finishing and garment care.
Actions that help
Correct construction choice and controlled setting improve performance, and they also keep the fabric near below 3% displacement. 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.
Actions that damage it
Excess heat, over-aggressive softener and missing washing-off steps all reduce results. 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.
Finishing influence
AATCC 179 skewness results shift noticeably after finishing, so retest after the final process rather than before. 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.
Garment care influence
Home washing temperature and drying method change performance over the first ten cycles. 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.
Summary
Keep process settings documented so repeat orders land inside the agreed range every time. 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.
