Slide fastener stringer and method of manufacturing the same

Abstract

A slide fastener stringer easily manufactured by a series of manufacturing steps with molding fastener elements in a warp yarn exclusion area formed on one side edge of a fastener tape, wherein a fastener tape is produced by weaving with warp yarns and weft yarns of synthetic fiber yarn; plural pieces of water soluble fiber yarns are disposed inside over plural pieces of the warp yarns from the side edge of the tape; in a dying step in a process for manufacturing a fastener stringer, the water soluble fiber yarns are dissolved to form the warp yarn exclusion area; and by molding the fastener elements by using the warp yarn exclusion area, the fastener stringer is manufactured in an easy sequential manufacturing process without applying any special processing.

1 . A slide fastener stringer, wherein a warp yarn exclusion area deprived of warp yarns is provided inside over plural pieces of the warp yarns from a side edge of a fastener tape, and fastener elements are formed in the warp yarn exclusion area.  
   
   
       2 . The slide fastener stringer according to  claim 1 , wherein a core thread is disposed between the side edge of the fastener tape and the warp yarn exclusion area.  
   
   
       3 . The slide fastener stringer according to  claim 2 , wherein at least one warp yarn is interposed between the core thread and the warp yarn exclusion area.  
   
   
       4 . The slide fastener stringer according to  claim 1 , wherein each of the fastener elements is formed integrally with a coupling head and a leg, the coupling head is disposed outside the side edge of the fastener tape and the leg is provided through the warp yarn exclusion area.  
   
   
       5 . The slide fastener stringer according to  claim 1 , wherein a leg strides over a weft yarn left in the warp yarn exclusion area on both front and rear surfaces thereof, and a front end portion of the leg is bonded to a warp yarn.  
   
   
       6 . A method of manufacturing a slide fastener stringer, comprising: a weaving step of weaving with a water soluble fiber yarn as a warp yarn, the water soluble fiber yarn disposed along a side edge of a fastener tape having a predetermined width; a heat set step of heat treating the fastener tape; a dying step of dying the fastener tape while dissolving the water soluble fiber yarn to form a warp yarn exclusion area; and a molding step of molding fastener elements by using the warp yarn exclusion area.
