Elastic Recovery How to Read It on a Lab Report
Laboratory reports present Elastic Recovery in a compact format. Knowing what each line means prevents misreading.
Definition reminder
how completely fabric returns after extension. Working figures for Elastic Recovery normally sit around above 90% after cycling in mainstream production. Note ISO 13934-1 recovery loop on the tech pack so nobody tests against an older revision.
Common report layout
The report states method ISO 13934-1 recovery loop, sample description, conditioning, and the measured result. Record elastane content alongside Elastic Recovery, because blends shift the measured value. A result outside above 90% after cycling usually points to process drift rather than to the fibre itself.
Typical result
Values near above 90% after cycling usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Elastic Recovery lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13934-1 recovery loop, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Elastic Recovery normally sit around above 90% after cycling in mainstream production. Note ISO 13934-1 recovery loop 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 Elastic Recovery, because blends shift the measured value. A result outside above 90% after cycling usually points to process drift rather than to the fibre itself.
