Double Knit Explained: How It Works in Performance Sportswear
Double Knit is best understood as any fabric knitted with two needle beds. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
any fabric knitted with two needle beds, which is why the value appears on almost every technical data sheet. Working figures for Double Knit normally sit around 200-340 GSM in mainstream production. Note double jersey machine on the tech pack so nobody tests against an older revision.
Why it matters in practice
