Snagging Resistance How to Read It on a Lab Report
Laboratory reports present Snagging Resistance in a compact format. Knowing what each line means prevents misreading.
Definition reminder
resistance to yarns being pulled out. Working figures for Snagging Resistance normally sit around grade 4 or better in mainstream production. Note ASTM D3939 snagging on the tech pack so nobody tests against an older revision.
Common report layout
The report states method ASTM D3939 snagging, sample description, conditioning, and the measured result. Record elastane content alongside Snagging Resistance, because blends shift the measured value. A result outside grade 4 or better usually points to process drift rather than to the fibre itself.
Typical result
Values near grade 4 or better usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Snagging Resistance lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ASTM D3939 snagging, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Snagging Resistance normally sit around grade 4 or better in mainstream production. Note ASTM D3939 snagging 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 Snagging Resistance, because blends shift the measured value. A result outside grade 4 or better usually points to process drift rather than to the fibre itself.
