Tear Strength Explained: How It Works in Performance Sportswear
Tear Strength is best understood as force needed to continue a tear. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
force needed to continue a tear, which is why the value appears on almost every technical data sheet. Working figures for Tear Strength normally sit around above 10 N typical in mainstream production. Note ISO 13937-2 trouser tear on the tech pack so nobody tests against an older revision.
Why it matters in practice
it matters mostly for woven shells, so it influences buying decisions more than most buyers expect. Record elastane content alongside Tear Strength, because blends shift the measured value. A result outside above 10 N typical usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
above 10 N typical. Ranges vary by construction, so compare like with like. Keeping reference values for Tear Strength lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13937-2 trouser tear, since both affect the reading.
How it is measured
ISO 13937-2 trouser tear is the reference normally quoted on a test report. Working figures for Tear Strength normally sit around above 10 N typical in mainstream production. Note ISO 13937-2 trouser tear on the tech pack so nobody tests against an older revision.
Frequent mistakes
Comparing results from different standards, testing unwashed fabric, and writing the target without tolerance are the common errors. Record elastane content alongside Tear Strength, because blends shift the measured value. A result outside above 10 N typical usually points to process drift rather than to the fibre itself.
