Bowing Explained: How It Works in Performance Sportswear
Bowing is best understood as curvature of courses across fabric width. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
curvature of courses across fabric width, which is why the value appears on almost every technical data sheet. Working figures for Bowing normally sit around below 2% deviation in mainstream production. Note mill inspection standard on the tech pack so nobody tests against an older revision.
Why it matters in practice
it causes pattern matching problems, so it influences buying decisions more than most buyers expect. Record elastane content alongside Bowing, because blends shift the measured value. A result outside below 2% deviation usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
below 2% deviation. Ranges vary by construction, so compare like with like. Keeping reference values for Bowing lets suppliers quote without extra sampling rounds. Ask for conditioning details together with mill inspection standard, since both affect the reading.
How it is measured
mill inspection standard is the reference normally quoted on a test report. Working figures for Bowing normally sit around below 2% deviation in mainstream production. Note mill inspection standard 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 Bowing, because blends shift the measured value. A result outside below 2% deviation usually points to process drift rather than to the fibre itself.
