A warp-knit tape structure is disclosed for use as a carrier tape for mounting thereon a row of fastener elements. The carrier tape has a web portion and adjoining marginal edge portion extending one longitudinal edge of the tape, said edge portion having a relatively wide interwale groove for the passage of a sewing machine needle and a plurality of wales adjacent to said interwale groove held closely together to provide a reinforced region disposed for sliding contact with a slider of the slide fastener.
