ABSTRACT:
A ventilated textile elastic band is formed of a crochet-type warp knitted construction from a set of warp yarns respectively formed in warpwise-extending chain stitches in spaced groups of successive adjacent wales separated from each other group by plural wales unoccupied by any warp yarn, a set of elastic yarns extending within the chain stitches of the warp yarns, and a set of filling yarns traversing coursewise within the warp yarn chain stitches in a predetermined filling traversal pattern producing an absence of any filling yarn in selected courses of the unoccupied wales thereby forming parallel lengthwise columns of spaced ventilation openings. The grouped arrangement of the warp yarns and the widthwise traversing of the filling yarns provides widthwise structural integrity to the fabric band while the elastic yarns provide lengthwise stretchability and the ventilation openings permit air and moisture to pass freely through the band.
