Fastening device with tape

Abstract

A tape of the fastening device made of synthetic resin is composed of an attachment area formed of one or more wales disposed at right and left edge portions of the tape in the width direction thereof and a fastener-molding area formed of plural wales in a center portion in the width direction. The warp knitted tape is entirely composed of a knitting structure formed by tangling of tricot stitch yarns and single cord stitch yarns, and chain stitch yarns are further knitted in the fastener-molding area so as to suppress stretching property in a warp direction of the area to a maximum extent and ensure a dimensional stability. The attachment area is composed of a knitting structure having required stretching property in its warp direction and some extent of stability in the dimensional form. Therefore, the fastening device with tape can be sewed to and along a curved line easily and can be adapted to an attachment object having stretching property well. Further, it allows engagement and disengagement of its fasteners securely and accurately, and enables continuous smooth molding of the fasteners made of synthetic resin onto the tape.
