Abstract
Ravel resistance is provided in the present warp knit elastic tape by incorporating a thermoplastic heat fusible binder yarn extending back and forth across the width of the elastic tape and in courses of stitch loops forming walewise extending stitch loop chains in the elastic tape. The elastic tape is then heated so that the thermoplastic heat fusible binder yarn softens and fuses to the remaining yarns in the elastic tape to prevent unraveling of the stitch loop chains across the entire width of the elastic tape.
