Fastening device with knitted tape

摘要

A tape (T) of the fastening device made of synthetic resin is composed of an attachment area (A) formed of one or more wales (W1-W6;W17-W22) disposed at right and left edge portions of the tape (T) in the width direction thereof and a fastener-molding area (B) formed of plural wales (W7-W16) in a center portion in the width direction. The warp knitted tape (T) is entirely composed of a knitting structure formed by tangling of tricot stitch yarns (11) and single cord stitch yarns (12), and chain stitch yarns (13) are further knitted in the fastener-molding area (B) so as to suppress stretching property in a warp direction of the area (B) to a maximum extent and ensure a dimensional stability. The attachment area (A) 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 (T).
