ABSTRACT:
An elastic warp knit fabric with ravel resistant features having a plurality of base yarns where each base yarn is knitted in successive courses to form a plurality of closed loops which extend in a warp direction and which form a plurality of individual wales. At least one of the wales is a locking wale forming one lateral edge of the fabric and another of the wales is an intermediate wale. An elastic yarn is laid into at least one of the intermediate wales and one of the locking wales. A first filler yarn extends in a weft direction in each course and is contained within the closed loops of adjacent wales to connect the wales together. A locking yarn is knitted in a locking wale to form an open loop in alternate courses where a portion of the locking yarn extends in a weft direction along with the filler yarn whereby the locking yarn prevents unraveling of the lateral edge of the fabric.
