Definitions
- the present invention relates to a slide fastener and a hidden slide fastener, and more particularly, to a slide fastener and a hidden slide fastener configured so that the weft of the woven fastener tape is hardly cut by the slider even when the slider is repeatedly slid.
- a slide fastener is attached to the opening, and the slider is slid along the element row in the separation direction or the meshing direction of the element row.
- the slide fastener is opened and closed.
- the slider is repeatedly slid over a long period of time, causing the fastener tape to wear due to friction generated between the slider and the fastener tape, and the slider comes into contact with the fastener tape.
- the problem is that the constituent yarns of the tape are cut and the fastener tape is damaged, which is a factor that shortens the life of the slide fastener.
- Patent Document 1 in order to prevent the fastener tape from being worn and the slide fastener from being damaged due to the sliding of the slider, a groove portion is formed on the side edge of the tape. A slide fastener is disclosed.
- the element row 103 is attached to the opposite side edges of the woven left and right fastener tapes 102.
- a pair of worn fastener stringers 101 and a slider 104 slidably disposed along the element row 103 are provided.
- the fastener tape 102 has a tape edge portion 102a that is thicker than the main tape portion and is disposed on the side edge of the tape, and a concave groove portion 102b that is formed on the front and back surfaces of the tape by press-contacting the fastener tape 102.
- the concave groove portion 102 b is arranged along the tape length direction at a position close to the element row 103.
- the upper and lower flange portions 104a and 104b of the slider 104 are arranged correspondingly to the recessed groove portions 102b arranged in the left and right fastener tapes 102, and the slider 104 attaches the upper and lower flange portions 104a and 104b to the fastener tape. It slides in the state inserted in the concave groove part 102b of 102.
- the concave groove portion 102b of the fastener tape 102 is formed by press-contacting the warp and the weft constituting the fastener tape 102. Therefore, the concave groove portion 102b is excessively slipped in the warp and the weft. It is said that it serves as a barrier for preventing breakage of the slide fastener 100 related to the slippage.
- the lower flange portion arranged on the lower wing plate of the slider in particular, the ridge line portion arranged between the upper end surface and the outer surface of the lower flange portion is in contact with the tape back surface of the fastener tape, and the tape length. Often moves along the direction. Further, even if the fastener tape 102 is provided with the concave groove portion 102b corresponding to the lower flange portion 104b of the slider 104 as in the above-mentioned Patent Document 1, the lower flange portion 104b contacts the fastener tape 102. It was extremely difficult to avoid this.
- the contact of the lower flange portion with the fastener tape is likely to occur when the slider is slid in the meshing direction of the element row so as to close the slide fastener. Often slidably contacted the tape surface.
- a fastener tape having a woven structure is generally formed by wefting a weft thread by reciprocating a carrier bar into a warp opening using a weft thread composed of a double thread and a plurality of warp threads.
- the warp of the fastener tape is arranged along a direction parallel to the sliding direction of the slider, and the weft is arranged along a direction orthogonal to the sliding direction of the slider. Warp and weft are exposed on both sides of the fastener tape.
- a slide fastener configured using a fastener tape having such a woven structure
- the slider when the slider is operated to slide by pulling the pull handle, the slider has a lower flange portion contacting the fastener tape as described above.
- the wefts arranged so as to be orthogonal to the sliding direction are easily damaged by the lower flange portion of the slider in the slider sliding direction. For this reason, there is a problem that the slide fastener cannot withstand long-term use because the lower flange portion cuts the weft and breaks the fastener tape by repeated sliding of the slider.
- the density of the warp is increased by increasing the number of warp yarns arranged on the tape part where the lower flange part of the fastener tape contacts. It is conceivable that the weft is hidden by the warp at the tape portion by increasing.
- the warp since the warp is arranged parallel to the sliding direction of the slider, it becomes stronger than the weft with respect to the sliding of the slider, so that the lower flange portion comes into contact with the warp when the slider slides.
- the warp is less likely to be cut by the lower flange than in the case of the weft. For this reason, it is conceivable to increase the warp density in the tape portion with which the lower flange portion comes into contact so that the weft is hidden from the lower flange portion, thereby making it difficult to cause the weft to be cut.
- the warp thread is difficult to cut even if the slider slides repeatedly, but the warp thread is pushed from the lower flange part.
- the warp position gradually shifts in the tape width direction, and misalignment occurs in the tape portion.
- the warp misalignment expands to extend in the tape length direction as the lower flange portion moves along the tape length direction of the fastener tape.
- the weft is completely exposed at the tape portion where the misalignment has occurred, as a result, the exposed weft is easily cut by the lower flange portion.
- a specific object of the present invention is to provide a woven fastener tape even if a part of the slider comes into contact with the fastener tape during sliding of the slider.

A woven region and an outer single woven region are formed.
- a slide fastener of the present invention for example, when a slider is slid by pulling a handle, the slider slides while being pulled obliquely upward as described above. At this time, since the fastener element inserted through the element guide path of the slider is also lifted upward together with the slider, the fastener tape is directed from the element mounting portion to which the fastener element is attached toward the outer edge of the tape. It curves so as to incline downward in the width direction, and the double woven region of the fastener tape comes into contact with the ridge line portion on the lower blade plate side of the slider.
