Abstract
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.
Claims12
A slide fastener comprising:
- a pair of fastener stringers in which an element row is attached along a tape inner side edge portion opposite to right and left woven fastener tapes and a slider capable of engaging and disengaging the element row;
- the slider having upper and lower blades, a guide post connecting between the upper and lower blades, and a ridge line portion between an opposed upper surface opposite to the upper blade at the side edge portion on the side of the lower blade and an outer side surface of the lower blade, wherein
- the 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 corresponding to the position of the ridge line portion of the slider, and
- 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 in the fastener tape.
A concealed type slide fastener comprising:
- a pair of concealed type fastener stringers having a folded tape portion folded into the U-shape between a tape main body portion and an element attaching portion of right and left woven fastener tapes in which a fastener element is attached to the element attaching portion in a state of projecting a coupling head of the fastener element outward from the folded tape portion, and a slider, which is capable of engaging and disengaging an element row of the fastener element;
- the slider having upper and lower blades, a guide post connecting between the upper and lower blades, and a lower flange portion erected in a standing upright state at the side edge portion of the lower blade;
- the lower flange portion having a ridge line portion between an opposed upper surface opposite to the upper blade and an outer side surface of the lower flange portion, wherein
- the 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 corresponding to a position of the ridge line portion of the slider, and
- 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 in the fastener tape.
