Also sometimes called double jersey, although inaccurately since interlock is not a jersey knit. It is, however, a type of double knit with two yarn feeds and sets of needles—creating fine (1 × 1) ribs on both sides of the fabric, interlocked together. As compared to jersey, which has an obvious reverse, interlock looks the same on both sides. It is more stable, and stretches lengthwise as well as widthwise. Its raw edges don’t curl.
Interlock knits can be of cotton, blends or manufactured fibers.
