Single Jersey Explained: How It Works in Performance Sportswear
Single Jersey is best understood as basic weft knit with one set of needles. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
basic weft knit with one set of needles, which is why the value appears on almost every technical data sheet. Working figures for Single Jersey normally sit around 140-220 GSM in mainstream production. Note circular single-bed machine on the tech pack so nobody tests against an older revision.
Why it matters in practice
it curls at the cut edge and needs careful finishing, so it influences buying decisions more than most buyers expect. Record elastane content alongside Single Jersey, because blends shift the measured value. A result outside 140-220 GSM usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
140-220 GSM. Ranges vary by construction, so compare like with like. Keeping reference values for Single Jersey lets suppliers quote without extra sampling rounds. Ask for conditioning details together with circular single-bed machine, since both affect the reading.
How it is measured
circular single-bed machine is the reference normally quoted on a test report. Working figures for Single Jersey normally sit around 140-220 GSM in mainstream production. Note circular single-bed machine 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 Single Jersey, because blends shift the measured value. A result outside 140-220 GSM usually points to process drift rather than to the fibre itself.
