Dimensional Stability What Improves It and What Damages It
Practical actions that raise or lower Dimensional Stability 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 under 3% length, 4% width. Working figures for Dimensional Stability normally sit around under 3% length, 4% width in mainstream production. Note AATCC 135 home laundering 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 Dimensional Stability, because blends shift the measured value. A result outside under 3% length, 4% width usually points to process drift rather than to the fibre itself.
Finishing influence
AATCC 135 home laundering results shift noticeably after finishing, so retest after the final process rather than before. Keeping reference values for Dimensional Stability lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 135 home laundering, since both affect the reading.
Garment care influence
Home washing temperature and drying method change performance over the first ten cycles. Working figures for Dimensional Stability normally sit around under 3% length, 4% width in mainstream production. Note AATCC 135 home laundering 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 Dimensional Stability, because blends shift the measured value. A result outside under 3% length, 4% width usually points to process drift rather than to the fibre itself.
