Abstract

An elastic knit fabric has pile loops on its back surface which are aligned in rows along the linear axis of the fabric and across the transverse axis of the fabric, the loops being disposed in standing relation with the openings in successive transverse rows being canted in opposite directions. The base web forming the fabric has successive courses parallel to its transverse axis and a plurality of parallel wales parallel to its linear axis. The pile yarns are knit to form a plurality of pile loops in the base web, each pile yarn having two stitches knit in successive first and second courses in a first wale, followed by two stitches knit in successive third and fourth courses in a second wale adjacent the first wale, followed by two stitches knit in successive fifth and sixth courses in the first wale. The pile loops are formed by the underlap as the pile yarn crosses back and forth between the first and second wales, whereby each pile yarn forms a pile loop every two courses. The base web comprises a plurality of needle yarns, each of which forms a stitch in an individual wale in each course, a plurality of elastomer yarns, each of which is laid in a wale, and top and bottom lay-in yarns traversing the entire width of the fabric. The pile loops are locked into the stitches formed by the needle yarns.
