A slide fastener tape, the fastener tape extending in a longitudinal direction and having a weave structure formed with warp threads arranged in the longitudinal direction and weft threads arranged along a transversal direction perpendicular to the longitudinal direction, the fastener tape including a cord arranged along one side edge portion of the fastener tape;
- wherein:
- the weft threads are made from filament yarns and the warp threads comprise a plurality of threads made from spun yarn;
- the spun yarn contains only short fibres;
- the fastener tape includes a main body portion;
- the side edge portion is an inner side edge portion to which fastener elements are attached;
- in the inner side edge portion, the cord is held and stabilized in a hollow weave structure formed at a side end edge of the fastener tape;
- the warp threads in the inner side edge portion include a plurality of spun yarns;
- the warp threads in the main body portion include a plurality of spun yarns;
- and
- the warp threads comprise a mixture of the spun yarns and the filament yarns.
A slide fastener comprising:
- a left fastener stringer and a right fastener stringer respectively comprising:
- a left fastener tape and a right fastener tape, each of the left fastener tape and the right fastener tape extending in a longitudinal direction, each of the fastener tapes having both a weave structure formed with warp threads arranged in the longitudinal direction, and weft threads arranged along a transversal direction perpendicular to the longitudinal direction, each of the fastener tapes comprising a cord and a row of fastener elements arranged along a respective side edge portion of the fastener tape, the side edge portions of the respective fastener tapes defining opposite, respective edges of the fastener tapes, wherein the weft threads are made from filament yarns and the warp threads comprise a plurality of threads made from spun yarn;
- and
- a slider for engaging and disengaging the rows of left and right fastener elements with and from each other;
- wherein:
- each row of fastener elements is formed by a plurality of fastener elements, which are discretely attached to the respective cord and the respective side edge portion;
- the slider has left and right side edges;
- the left and right fastener tapes are woven with a single-woven structure;
- and
- each of the left and right fastener tapes comprises a respective longitudinally extending side tape portion, bridging the respective left or right side edges of the slider, wherein the side tape portions are woven with a double-woven structure;
- and
- the warp threads in the double-woven structure have a shorter diameter than the warp threads in the single-woven structure.
