Two-Way Stretch How to Read It on a Lab Report
Laboratory reports present Two-Way Stretch in a compact format. Knowing what each line means prevents misreading.
Definition reminder
extension mainly across the width. 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.
Common report layout
The report states method ASTM D6614 stretch woven test, sample description, conditioning, and the measured result. 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.
Typical result
Values near 20-40% typical usually indicate a conforming lot, assuming the fabric matches the sample submitted. 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.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. 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.
Questions to ask
Ask the laboratory for the standard revision and sample description before accepting or rejecting a result. 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.
