Fastener stringer provided with rows of metal elements, slide fastener provided with same, and article provided with slide fastener

Abstract

A fastener stringer includes a fastener tape having a first side edge and a second side edge opposite to the first side edge, and a row of metal elements attached along the first side edge; wherein a water-soluble thread is used in a portion of the fastener tape that is closer to the first side edge than a center line C of the fastener tape, and the fastener stringer is configured such that by dissolving the water-soluble thread, an attachment strength of the row of metal elements is reduced and/or the fastener tape separates into at least two parts starting from the water-soluble thread.

1 . A fastener stringer, comprising a fastener tape having a first side edge and a second side edge opposite to the first side edge, and a row of metal elements attached along the first side edge;
 wherein a water-soluble thread is used in a portion of the fastener tape that is closer to the first side edge than a center line C of the fastener tape, and the fastener stringer is configured such that by dissolving the water-soluble thread, an attachment strength of the row of metal elements is reduced and/or the fastener tape separates into at least two parts starting from the water-soluble thread.   
     
     
         2 . The fastener stringer according to  claim 1 , wherein the row of metal elements is swaged and fixed so as to sandwich at least one core string provided along the first side edge of the fastener tape, and the water-soluble thread constitutes at least a part of the at least one core string. 
     
     
         3 . The fastener stringer according to  claim 1 , wherein the at least one core string comprises at least one core thread and a sheath thread woven around the core thread, and the water-soluble thread constitutes at least a part of the core thread. 
     
     
         4 . The fastener stringer according to  claim 1 , comprising at least one core string sewn along the first side edge of the fastener tape by the water-soluble thread, and wherein the row of metal elements is swaged and fixed so as to sandwich the at least one core string. 
     
     
         5 . The fastener stringer according to  claim 1 , wherein the fastener tape comprises: a first fastener tape portion having the first side edge and having a first width extending in a direction orthogonal to the first side edge;
 and a second fastener tape portion having the second side edge and having a second width extending in a direction orthogonal to the second side edge,   wherein an average value of the first width is smaller than an average value of the second width, and the first fastener tape portion and the second fastener tape portion are sewn together with the water-soluble thread.   
     
     
         6 . A slide fastener comprising the fastener stringer according to  claim 1 . 
     
     
         7 . An article comprising the slide fastener according to  claim 6 , wherein the slide fastener is sewn along the second side edge of the fastener tape. 
     
     
         8 . The article according to  claim 7 , wherein the fastener tape  1  comprises a same material as that used in the article.
