Snagging Resistance What Improves It and What Damages It
Practical actions that raise or lower Snagging Resistance 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 grade 4 or better. 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.
Actions that damage it
Excess heat, over-aggressive softener and missing washing-off steps all reduce results. 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.
Finishing influence
ASTM D3939 snagging results shift noticeably after finishing, so retest after the final process rather than before. 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.
Garment care influence
Home washing temperature and drying method change performance over the first ten cycles. 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.
Summary
Keep process settings documented so repeat orders land inside the agreed range every time. 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.
