Dimensional Stability Frequently Asked Questions
Short answers to the questions buyers ask most often about Dimensional Stability.
What does it mean?
size change after washing. 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.
What value should be specified?
Start from under 3% length, 4% width and adjust for the end use of the garment. 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.
How is it tested?
AATCC 135 home laundering. 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.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. 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.
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 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.
