Fastener tape, method for identifying same, method for manufacturing same, and slide fastener set

Abstract

Fastener tape is woven from a weft thread and warp threads both of which are threads with a main attribute. The fastener tape includes: first and second side-edges extending along an elongation direction of the fastener tape to define a fastener tape width; and a tape main portion interposed between the first and second side-edges. The tape main portion includes an identification region woven by plural warp threads and the weft thread interlaced with one another, the identification region having an identification region width which is a partial width of an entire width of the fastener tape width and is a width in accordance with a number of the plural warp threads. Structure of the identification region is configured to allow identification that the weft thread and the warp threads are with the main attribute and/or to allow identification of a sub-attribute subdivided from the main attribute.
