Fastener stringer and slide fastener

摘要

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.

主权项

1. A fastener stringer for a slide fastener in which a continuous fastener element formed of a monofilament is attached to a tape side edge portion of a fastener tape and at least a part of the fastener element is subjected to coloration or surface treatment, wherein:
the fastener element includes a plurality of fine projected rims which are continuously disposed on a peripheral surface of the monofilament along a length direction of the monofilament and a plurality of fine concave grooves which are disposed between the projected rims; and in a cross section of the monofilament, a cross-sectional area of a space region of the concave groove which is defined by connecting apexes of the adjacent projected rims is set to be larger than a cross-sectional area of the projected rim which is defined by connecting bottoms of the adjacent concave grooves.
