Snagging Resistance Why Shipments Get Rejected Over This
Many disputes come down to Snagging Resistance. Below is what inspectors check and why shipments fail.
The core definition
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.
Most common cause of failure
Results usually fall outside grade 4 or better because the target was never written into the order. 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 it is checked
Inspection and laboratory work both refer to 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.
Related faults
mesh and low-density knits score lower, so related complaints often point back to this single parameter. 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.
Avoiding rejection
Agree targets, tolerances and the method before production, then test per lot rather than per shipment. 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.
