Two-Way Stretch What Improves It and What Damages It
Practical actions that raise or lower Two-Way Stretch 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 20-40% typical. Working figures for Two-Way Stretch normally sit around 20-40% typical in mainstream production. Note ASTM D6614 stretch woven test 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 Two-Way Stretch, because blends shift the measured value. A result outside 20-40% typical usually points to process drift rather than to the fibre itself.
Finishing influence
ASTM D6614 stretch woven test results shift noticeably after finishing, so retest after the final process rather than before. Keeping reference values for Two-Way Stretch lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ASTM D6614 stretch woven test, since both affect the reading.
Garment care influence
Home washing temperature and drying method change performance over the first ten cycles. Working figures for Two-Way Stretch normally sit around 20-40% typical in mainstream production. Note ASTM D6614 stretch woven test 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 Two-Way Stretch, because blends shift the measured value. A result outside 20-40% typical usually points to process drift rather than to the fibre itself.
