Snagging Resistance Frequently Asked Questions
Short answers to the questions buyers ask most often about Snagging Resistance.
What does it mean?
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.
What value should be specified?
Start from grade 4 or better and adjust for the end use of the garment. 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.
How is it tested?
ASTM D3939 snagging. 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.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. 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.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. 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.
