FIG. 10 is a front view of a well known fastener tape. - A slide fastener stringer and a method of manufacturing the same according to the invention will be described. In the slide fastener stringer, as shown in
FIG. 1 , multi-filaments of polyester fiber or polyamide fiber are used forwarp yarns 2 andweft yarns 3, and afastener tape 1 is produced by needle weaving with theweft yarn 3 by double picks. In thefastener tape 1, a warpyarn exclusion area 12 in which nowarp yarns 2 exist by excludingcorresponding warp yarns 2 is formed inside over plural pieces of thewarp yarns 2 from aside edge 5, and as a result, plural pieces of thewarp yarns 2 are removed while only theweft yarns 3 remain in the warp yarn exclusion area. In the warpyarn exclusion area 12, aleg 15 of thefastener element 13 is molded due to injection molding by using such thermoplastic resin as polyamide and polyacetal on theremaining weft yarns 3 at a constant pitch so as to be closely-attached to front and rear surfaces, thereby producing a fastener stringer as shown inFIG. 7 . Alternately, thefastener elements 13 are formed due to die-cast molding by using such metal as zinc alloy and aluminum alloy in the warpyarn exclusion area 12, thereby producing the fastener stringer. In the meantime, because plural pieces of thewarp yarns 2 existing between theside edge 5 and the warpyarn exclusion area 12 are covered with thefastener elements 13 formed in the warpyarn exclusion area 12, they are fixed with a sufficient mounting strength. - As means for forming the warp
yarn exclusion area 12 in thefastener tape 1, plural pieces of watersoluble fiber yarns 4, for example, water soluble vinylon are disposed inside over plural pieces of thewarp yarns 2 from theside edge 5 of thetape 1 and the fastener tape is woven, as shown inFIG. 2 . Alternatively, it is permissible to weave afastener tape 1 of a type in which acore thread 6 is disposed as shown inFIGS. 4 and6 . In thewoven fastener tape 1, the warp yarns as the watersoluble fiber yarns 4 are dissolved in a dying solution in a dying step in the manufacturing process and removed to form the warpyarn exclusion area 12. - As for the method of manufacturing the slide fastener stringer, first, the
fastener tape 1 shown inFIG. 2 is needle woven with double picks by using thewarp yarn 2 and theweft yarn 3. At this time, plural pieces of watersoluble fiber yarns 4 are disposed as thewarp yarns 2 inside of plural pieces of thewarp yarns 2 placed along theside edge 5 of thefastener tape 1. In this weaving step, thefastener tape 1 of a type in which thecore thread 6 is used as shown inFIGS. 4 and6 may be woven. Next in a heat set step in which thewoven fastener tape 1 is heat treated by dry heat, deviation of stitch in thefastener tape 1 is prevented to stabilize the configuration of the fastener tape. Thereafter, thefastener tape 1 is sent to the dying step, in which thefastener tape 1 is passed in a dying solution to dissolve the watersoluble fiber yarns 4, and as a consequence, a warpyarn exclusion area 12 in which nowarp yarn 2 exists is formed in thefastener tape 1. - After the warp
yarn exclusion area 12 is formed, thefastener tape 1 is sent to a molding step, in which thefastener elements 13 are molded at a constant pitch due to injection molding by using such thermoplastic resin as polyacetal and polyamide in the warpyarn exclusion area 12, thereby producing the fastener stringer as shown inFIG. 7 . In the molding step, thefastener elements 13 may be formed due to die-cast molding by using such metal as zinc alloy and aluminum alloy in theexclusion area 12, thereby producing the fastener stringer. As for the method of manufacturing the fastener stringer of the present invention, as shown inFIG. 8 , the fastener stringer is produced through the weaving step, the heat set step, the dying step and the molding step. A produced fastener stringer is cut to a predetermined length, a top stop end and a bottom stop end or an opening device is mounted on each of right and left fastener stringers, and then, a slider is loaded thereon, thereby finishing various kinds of the slide fasteners. - A slide fastener stringer of a first embodiment of the present invention shown in
FIG. 1 is woven withwarp yarns 2 andweft yarns 3 formed of multi-filament yarns of polyester fiber or polyamide fiber. Thefastener tape 1 is produced by needle weaving with theweft yarn 3 by double picks. In thefastener tape 1, a warpyarn exclusion area 12, in which only theweft yarns 3 exist, is provided inside of plural pieces of thewarp yarns 2 placed along aside edge 5 by removing plural pieces of thewarp yarns 2.Fastener elements 13 having an appropriate shape are injection molded in the warpyarn exclusion area 12 by using such thermoplastic resin as polyacetal and polyamide. Acoupling head 14 of thefastener element 13 is projected outward from theside edge 5 of thefastener tape 1, and theleg 15 or afront end portion 16 of the leg is formed so as to adhere to theweft yarn 3 existing in the warpyarn exclusion area 12 and thewarp yarn 2 facing the warpyarn exclusion area 12 from both the front and rear surfaces, thereby producing the fastener stringer shown inFIG. 7 . - By using the
warp yarn 2 andweft yarn 3 for the double picks each having a size of 330 dtex, thefastener tape 1 is woven into an appropriate weaving structure, for example, a herringbone weaving structure, as shown inFIG. 2 . In this case, plural pieces of watersoluble fiber yarns 4 made of water soluble vinylon having 1220 dtex are disposed inside of plural pieces of thewarp yarns 2 placed along theside edge 5 of thefastener tape 1. Because the watersoluble fiber yarn 4 is dissolved in water of 70°C, it is dissolved at a stage where thefastener tape 1 is dyed. - A slide fastener stringer of a second embodiment of the present invention shown in
FIG. 3 is woven withwarp yarns 2 andweft yarns 3 formed of multi-filament yarns of polyester fiber or polyamide fiber. Thefastener tape 1 is produced by needle weaving by double pick with theweft yarn 3, and acore thread 6 having a large diameter is woven into aside edge 5 of thefastener tape 1. As thecore thread 6, several pieces of multi-filament yarns of polyester fiber or polyamide fiber are used, and the same kind of the multi-filament yarn is braided around it to produce thecore thread 6. A warpyarn exclusion area 12 in which only theweft yarns 3 exist is provided at a portion corresponding to plural pieces of thewarp yarns 2 adjacent to thecore thread 6 in thefastener tape 1.Fastener elements 13 of an appropriate shape are injection molded in the warpyarn exclusion area 12 by using such thermoplastic resin as polyacetal and polyamide. - A
coupling head 14 of thefastener element 13 is projected outward from theside edge 5 of thefastener tape 1, and aleg 15 surrounds thecore thread 6 while theleg 15 and thefront end portion 16 fix theweft yarn 3 existing in the warpyarn exclusion area 12 and thewarp yarn 2 facing the warpyarn exclusion area 12 from the front and rear surfaces, thereby forming the fastener stringer shown inFIG. 7 . As shown inFIG. 4 , plural pieces of water soluble vinylon which is watersoluble fiber yarn 4 are disposed adjacent to thecore thread 6 arranged along theside edge 5. - A slide fastener stringer of a third embodiment of the present invention shown in
FIG. 5 is woven withwarp yarns 2 andweft yarns 3 formed of multi-filament yarns of polyester fiber or polyamide fiber. Thefastener tape 1 is produced by needle weaving by double picks with theweft yarns 3, and acore thread 6 having a small diameter is woven into aside edge 5 on both the front and rear surfaces of thefastener tape 1. As thecore thread 6, a single piece of multi-filament yarn of polyester fiber or polyamide fiber is used, and the same kind of the multi-filament yarn is braided around it so as to produce thecore thread 6. In thefastener tape 1, thewarp yarns 2 are disposed adjacent to thecore thread 6, and then, the warpyarn exclusion area 12 in which only theweft yarns 3 exist is provided at a portion corresponding to plural pieces of thewarp yarns 2 adjacent to thesewarp yarns 2. Then,fastener elements 13 of an appropriate shape are injection molded in the warpyarn exclusion area 12 by using such thermoplastic resin as polyacetal and polyamide. Acoupling head 14 of thefastener element 13 is projected outward from theside edge 5 of thefastener tape 1, and aleg 15 surrounds thecore thread 6 while theleg 15 and thefront end portion 16 fix theweft yarn 3 existing in the warpyarn exclusion area 12 and thewarp yarn 2 facing the warpyarn exclusion area 12 from the front and rear surfaces, thereby producing the fastener stringer shown inFIG. 7 . In thefastener tape 1, as shown inFIG. 6 , plural pieces of water soluble vinylon which is watersoluble fiber yarn 4 are disposed adjacent to thecore thread 6 arranged on the front and rear surfaces of theside edge 5. - If speaking of a method of manufacturing the slide fastener stringer described in the respective embodiments, the fastener stringer is manufactured according to manufacturing steps shown in
FIG. 8 . First, in a weaving step, thewarp yarns 2 of 330 dtex formed of multi-filament yarns of polyester fiber or polyamide fiber are arranged to a predetermined width of 13 to 16 mm of apredetermined fastener tape 1. At this time, the watersoluble fiber yarns 4 of 1220 dtex, for example, water soluble vinylon are disposed at a position inward by plural pieces from thewarp yarn 2 on theside edge 5. Then, there is disposed, on theside edge 5, thecore thread 6 having a large diameter, for example, acore thread 6 in which several pieces of multi-filament yarns of polyester fiber or polyamide fiber are used as a core while the same kind of the multi-filament yarns are braided around it. Alternatively, on theside edge 5 is vertically disposed thecore thread 6 having a small diameter, for example, thecore thread 6 in which the a single piece of multi-filament yarn of polyester fiber or polyamide fiber is used as a core while the same kind of the multi-filament yarns are braided around it. Then, theweft yarn 3 of the same type as thewarp yarn 2 is weft inserted into the arrangedwarp yarn 3, watersoluble fiber yarn 4 or thecore thread 6 by double picks in the needle weaving, so that thefastener tape 1 as shown inFIGS. 2 ,4 and6 is woven with an appropriate weaving structure, for example, a herringbone weaving structure. - The woven
fastener tape 1 is sent to a next heat set step, in which thefastener tape 1 is heat treated by dry heat of around 180°C so as to better the texture of thefastener tape 1 and stabilize is configuration. Thereafter, thefastener tape 1 is sent to a dying step, in which thefastener tape 1 is dyed in a dying solution of around 130°C. At the same time, the watersoluble fiber yarn 4 composed of water soluble vinylon is dissolved in the dying solution, so that, as shown inFIG. 9 , the watersoluble fiber yarns 4 woven into thefastener tape 1 shown inFIG. 6 is dissolved, and the warpyarn exclusion area 12 in which only theweft yarns 3 are left is formed when thefastener tape 1 is dyed. - After dyed, the
fastener tape 1 is sent to a molding step to mold thefastener elements 13. In the molding step, thefastener elements 13 having various kinds of shape is formed in the warpyarn exclusion area 12 in thefastener tape 1 by injection molding means using such thermoplastic resin as polyacetal and polyamide, thereby producing the fastener stringer of resin shown inFIG. 7 . - In the molding step, the
fastener elements 13 may be molded in the warpyarn exclusion area 12 formed in thefastener tape 1 by die-cast molding means using such metal as zinc alloy and aluminum alloy, thereby manufacturing a metallic fastener stringer. - Finally, the fastener stringer is cut out to a predetermined length, and a top end stop and a bottom end stop are mounted on front and rear ends of a cut piece or an opening device is mounted to combine right and left fastener stringers. Then, a slider is loaded thereon to finish the slide fastener.
- In the slide fastener stringer of the present invention, thermoplastic resin or the like is injection molded on a tape side edge to form fastener elements. The fastener elements are mounted such that their legs pass through the tape. The slide fastener is finished with a rigid structure and can be applied to not only clothing but also a product on which a force is applied, such as bags and various kinds of cases.
