Embodiment Construction

[0037] The embodiments of slide fasteners according to the present invention are hereunder specifically explained referring to the drawings.

[0038]FIG. 1 shows a slide fastener according to the present invention.

[0039] As the first feature of the slide fastener, a special performance mechanism is provided to the basic functions of the slide faster. More specifically, in order to provide the faster tape 2 of a fastener stringer 1 with electromagnetic wave shield performance, metal plating is applied onto the surface of the fastener tape 2 to form a shield coating 7. In addition, in order to provide the fastener tape 2 further with fire-resistant performance, the surface of the shield coating 7 formed on the surface of the fastener tape 2 is coated with a fire-resistant additive and thus the fire-resistant coating 7 is formed.

[0040] The second feature of the slide fastener is as follows. Before attaching fastener elements 3 to the fastener tape 2 of a fastener stringer 1, the fasten...

Abstract

A fastener element 3 is attached to a first edge part 12 of a fastener tape 2 and the fastener tape 2 is sewn in the vicinity of the installation part 5 of the fastener element 3 with a sewing thread 6 continuously extending in the longitudinal direction of the fastener tape 2. The fastener tape 2 is easily subjected to plating to form a shield coating 7 or to coating of a fire-resistant additive and thus the fastener tape 2 can obtain electromagnetic wave shield performance and further fire-resistant performance.

Description

TECHNICAL FIELD [0001] The present invention relates to a slide fastener having electromagnetic wave shield performance capable of shielding interfering electromagnetic waves or fire-resistant performance of low flammability. BACKGROUND ART [0002] In recent years, slide fasteners having special performance such as electromagnetic wave shield performance and fire-resistant performance have been required to be provided at a low cost without the degradation of quality as well as to effectively exhibit the special performance. [0003] For example, as a conventional electromagnetic wave shield slide fastener, an electromagnetic wave shield slide fastener 99 which is fabricated through the steps of: forming a wire-mesh 97 weft-knitted with thin wires into a bag shape as an electromagnetic wave shield member 98; inserting a core material having a core string part 96 formed at an edge part thereof into the bag-shaped part of the electromagnetic wave shield member 98 to form a fastener tape 9...
