[0032] Hereinafter, preferred embodiments of the present invention will be specifically described based on examples shown in the drawings. Figures 1-3 show a first embodiment of the invention, and Figure 1 is a front perspective view of a portion of a knitted zipper, schematically showing the installation of a continuous row of zipper elements. figure 2 is the entire warp structure diagram representing the same zipper with its omitted part, and image 3 is the warp knitting structure diagram of each knitting yarn in the same knitting zipper.

[0033] Meanwhile, although FIG. 1 shows a situation in which the zipper element mounting part is shown as the center of the figure, and the main part of the zipper tape is omitted and each knitting yarn is loose for easy understanding, it can be understood that the actual knitting pattern and each knitting yarn The coiled part is tightly pulled tightly. In addition, although knitting yarns having various sizes are shown in the same fig...

[0058] FIG. 6 shows a second embodiment of the present invention, and its zipper stringer 10 has the same knitting structure as that of the first embodiment. However, according to this embodiment, the fixed chain knitting yarn (F) is not composed of composite fiber yarn but ordinary synthetic fiber material. And the warp-lining yarns (G1-G4) of all the zipper element mounting portions 13 are composite fiber yarns composed of heat-shrinkable fiber material (SM) and heat-melt fiber material (MM). According to this embodiment, the fixed chain knitting yarn (F) may also consist of the same composite fiber yarn as the warp laying yarns (G1-G4), as in the first embodiment. This function is substantially the same as that of the first embodiment.

[0060] Figure 7 A third embodiment of the present invention is shown, and the knitting structure of its zipper stringer 10 is the same as that of the first embodiment. However, also according to this embodiment, the fixed chain knitting yarn (F) is composed of ordinary fiber yarns, and the weft insertion yarns (C) and (D) which are constituent yarns of the fastener element mounting portion 13 are composed of the composite fiber yarns of the present invention. Composition, which consists of heat-shrinkable fiber material (SM) and heat-melt fiber material (MM). According to this embodiment, the fixed chain knitting yarn (F) may also consist of the same composite fiber yarn as in the first embodiment, and in this case, the composite fiber yarn may be the same as the weft inserted yarn (C) and ( D) Same material. Its function is substantially the same as that of the first and second embodiments.

[0061] Furthermore, all the fixed chain knitting yarns (F), warp-lining yarns (G...

Abstract

A knitted-in slide fastener comprising a continuous fastener element row (14) which is knitted in at the same time as knitting of a fastener tape (11), wherein a fastener element mounting portion (13) on a side edge portion in the longitudinal direction of the warp knitted fastener tape (11) is knitted with a fixing knitting yarn (F) for sandwiching and fixing upper and lower leg portions of each fastener element (15) in a direction of front and rear of the fastener tape and other knitting yarns (C, D, G1 to G4). Part of these composition yarns is composed of composite fiber yarns formed of heat shrinkage fiber material (SM) and heat fusion fiber material (MM), and the heat shrinkage fiber material (SM) is shrunk by heat treatment and at the same time, the heat fusion fiber material (MM) is fused with other the composition yarns (F, C, D, G1 to G4) in the vicinity thereof. Consequently, no fraying occurs in yarns even if a knitting yarn, which forms the fastener element mounting portion, is cut out so that the fastener element row of that portion is not separated from the fastener tape.

Description

technical field [0001] The present invention relates to a knitted slide fastener in which a fastener tape is composed of a warp-knitted structure, and at the same time continuous rows of fastener elements made of thermoplastic synthetic resin monofilament are woven in and fixed. In particular, the present invention relates to a knitted slide fastener in which the knitting structure of the fastener element mounting portion is finely formed so as to stabilize the resin between the fastener elements, and the constituent yarns are free from fraying or tearing even when a sewing needle cuts the constituent yarns of the fastener element mounting portion. Rows of zipper elements do not separate. Background technique [0002] For example, Japanese Patent Application Laid-Open No. 8-314 has disclosed a knitted slide fastener in which continuous rows of fastener elements are knitted into and fixed to fastener element mounting portions along the longitudinal sides of the fastener tape...
