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.

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

A fastener tape includes a first side-edge portion including a core cord and a plurality of first ground warp yarns; and a tape main portion adjacently positioned to the first side-edge portion and including a plurality of second ground warp yarns. A weft yarn and every ground warp yarn of the fastener tape are yarns including plant-derived resin. The first ground warp yarn is FDY (Fully Drawn Yarn) and the second ground warp yarn is DTY (Drawn Textured Yarn) and in accordance with this difference in yarn type, a thermal shrinkage ratio of the first ground warp yarn is greater than a thermal shrinkage ratio of the second ground warp yarn.

Fastener tape woven from yarns including plant-derived resin, fastener stringer and method of producing the same

Slide fastener coupled to flexible member includes: a pair of fastener stringers, each of the fastener stringers having a fastener tape provided with a first side-edge portion and a second side-edge portion which extend in an elongation direction of the fastener tape, and a fastener element provided on the first side-edge portion side; and one or more sliders for opening and closing the pair of fastener stringers. The fastener tape includes a first tape region onto which a flap of the flexible member is overlaid and a second tape region positioned between the first tape region and the second side-edge portion. The flap is interposed between the first tape region and the second tape region.

Slide fastener joined to flexible material

There is provided a slide fastener. A pair of fastener element rows are respectively sewn to opposing tape side edge portions of a pair of fastener tapes with sewing threads. Each of the fastener element rows has a plurality of fastener elements. A slider is configured to engage and disengage the pair of fastener element rows. The pair of fastener tapes and the pair of fastener element rows are colored in different colors. The slide fastener is used such that the fastener element rows are at a back side. A width dimension of a gap between the pair of fastener tapes is set to be 10 to 25% of a width dimension of the pair of fastener element rows that are engaged with each other. The color of the fastener element rows is visible through the gap from a front side of the slide fastener.

Slide fastener and method for manufacturing slide fastener

In a slide fastener, a fastener tape is woven with a single-woven structure, and in the fastener tape, a double-woven region woven with a double-woven structure is formed along a tape longitudinal direction. An inner single-woven region and an outer single-woven region of the single-woven structure are formed at a tape inner edge side and a tape outer edge side of the double-woven region. Thus, even if the fastener tape makes contact with ridge line portions on a lower blade side of the slider when the slider is slid, weft yarns arranged in the double-woven region are less likely to be cut.

Slide fastener

Chain for slide fastener

A stretchable fastener stringer for a slide fastener includes a fastener tape having a tape main portion and an element attaching portion and a continuous fastener element which is attached to the element attaching portion. The fastener tape has stretchability due to an elastic yarn being combined by weaving or knitting and the fastener element includes a coupling head, upper and lower leg portions which are extended from the coupling head and a connecting portion which connects the upper and lower leg portions, therebetween of adjacent fastener elements. In this fastener stringer, a value of a bulging ratio which is the ratio between a dimension of the coupling head in the tape longitudinal direction and a dimension of the upper and lower leg portions in the tape longitudinal direction is set to be larger than 1.80 and not larger than 2.33.

Stretchable fastener stringer and slide fastener

A curved slide fastener in which a convex element attaching edge portion which is curved convexly and outwardly and a concave element attaching edge portion which is curved concavely and inwardly are arranged to face each other on opposing side edges of a pair of fastener tapes, a stretchable member which is elastically deformed so as to be stretchable in a length direction of the fastener tape is attached to an edge side of the fastener tape on an opposite side to the convex element attaching edge portion, and the stretchable member is fixed to the fastener tape in a contracted state and maintains a foundation structure of the fastener tape in a contracted state, thereby preventing occurrence of wrinkle or swelling on the tape surface.
