Fastener stringer and slide fastener

Abstract

A fastener stringer, is configured such that a fastener element of a continuous shape includes a plurality of fine projected rims which are continuously disposed on a peripheral surface of the monofilament (30); along a length direction of the monofilament and a plurality of fine concave grooves which are disposed between the projected rim and in a cross section of the monofilament, a cross-sectional area of a space region of the concave groove is set to be larger than that of the projected rim. With this configuration, when performing dyeing process employing a beam dyeing or a continuous dyeing method while appropriately securing the strength of the monofilament, it is possible to prevent dyeing irregularities and dyeing defects from arising. Further, when performing a coloring according to an inkjet, scheme, it is possible to finely form a desired pattern with clear outlines on the fastener element.
