Abstract: A fastener stringer has a fastener tape provided with a tape main body portion and an element attaching portion and a plurality of fastener elements fixed by weaving to the element attaching portion of the fastener tape at the same time of weaving of the fastener tape, and is provided with a weaving structure with one pitch per one-rotation. A weft yarn of the fastener tape has a fineness larger than that of at least a part of a warp yarns disposed in the tape main body portion. Thereby, the productivity of the fastener stringer can be increased to reduce the cost. Further, the density of the weft yarn in the fastener tape can be increased, and the fastener tape can be less likely to be misaligned.

Each helical unit included in the configured helix of the monofilament includes a pair of legs, a first coupling portion coupled between said pair of legs, and a second coupling portion coupled between one leg of said pair of legs and the other leg of a pair of legs in an adjacent helical unit.

Therefore, hiding performance of the hidden slide fastener can be enhanced.

Abstract: There is provided a knit-in slide fastener in which a continuous fastener element row is knitted simultaneously with the knitting of a warp knitted fastener tape at a fastener element mounting portion on a longitudinal side edge portion of the fastener tape. Since a yarn composed of ordinary long fibers, or a textured yarn is employed as a fixing knitting yarn for the fastener element mounting portion, even if a sewing needle is pierced into the textured yarn, the fixing knitting yarn is never cut off because the sewing needle passes through a number of fibers which compose the textured yarn. Further, even when part of the fibers are cut off, no fraying occurs in the yarns, so that the fastener element row at the cut off portions does not separate from the fastener tape.

Abstract: A main portion of a fastener tape is woven with transparent or semi-transparent synthetic fiber monofilament yarn as warp yarn and weft yarn. Plural flexible yarns are interwoven into a side edge portion of the fastener tape in a longitudinal direction of the tape so as to form a fastener-element-mounting portion for mounting fastener elements. The fastener-element-mounting portion may be formed of an interwoven portion having a flat surface, in which case continuous fastener elements are to be attached thereto. Alternatively, a swollen core portion may be formed on the surface of the fastener-element-mounting portion, in which case single-type separate fastener elements are to be attached thereto. As a flexible yarn, a finished yarn having a bulk and produced by textured processing multifilament yarn is used so that mounting of the fastener elements are facilitated and the configuration of the fastener tape is stabilized.

Abstract: In a fastener tape having a tape main portion obtained by weaving and an element-mounting edge portion in which core strings are woven, foundation warps used for the tape main portion have a lower thermal contraction coefficient than the other warps. The core strings have a high thermal contraction coefficient. The warps adjacent to the core strings at an inner side thereof have a thermal contraction coefficient lower than that of the core strings. Therefore, it is possible to obtain a fastener stringer in which no puckering occurs in an element-mounting edge portion even after elements are attached, so that linearity can be secured.

Fastener elements of various types may be fitted to the reinforced section of the fastener tape of the a fastener stringer, thus the fastener stringer has a beautiful ornamental portion. When multicolored yarns are used for several warps or warp knitting yarns located adjacent to the reinforced section, a broadened ornamental portion can be produced to enhance the color effect of the fastener stringer that may be used for a dress to improve its color effect.
