Fabric Growth How to Read It on a Lab Report
Laboratory reports present Fabric Growth in a compact format. Knowing what each line means prevents misreading.
Definition reminder
permanent elongation left after extension. Working figures for Fabric Growth normally sit around below 6% target in mainstream production. Note ASTM D2594 stretch properties on the tech pack so nobody tests against an older revision.
Common report layout
The report states method ASTM D2594 stretch properties, sample description, conditioning, and the measured result. Record elastane content alongside Fabric Growth, because blends shift the measured value. A result outside below 6% target usually points to process drift rather than to the fibre itself.
Typical result
Values near below 6% target usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Fabric Growth lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ASTM D2594 stretch properties, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Fabric Growth normally sit around below 6% target in mainstream production. Note ASTM D2594 stretch properties 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 Fabric Growth, because blends shift the measured value. A result outside below 6% target usually points to process drift rather than to the fibre itself.
