Fastener tape

Abstract

There is provided a fastener tape that satisfies a predetermined standard of peeling resistance between a reinforcing portion and a fastener tape body without using an anchor coating agent and in a simple manner. A fastener tape includes a fastener tape body, and a reinforcing portion provided on at least one main surface of the fastener tape body, wherein the reinforcing portion is a single layer comprising a polypropylene resin, and is impregnated and solidified in the fastener tape body.

1 . A fastener tape, comprising a fastener tape body, and a reinforcing portion provided on at least one main surface of the fastener tape body,
 wherein the reinforcing portion is a single layer comprising a polypropylene resin, and is impregnated and solidified in the fastener tape body.   
     
     
         2 . The fastener tape according to  claim 1 , wherein the reinforcing portion and the fastener tape body are crosslinked. 
     
     
         3 . The fastener tape according to  claim 2 , wherein the fastener tape body comprises polyethylene terephthalate, and the reinforcing portion and the fastener tape body are crosslinked by carbodiimide. 
     
     
         4 . The fastener tape according to  claim 1 , wherein the reinforcing portion and the fastener tape body are crosslinked by cyclic carbodiimide. 
     
     
         5 . The fastener tape according to  claim 1 , wherein a thickness d of a fraction in the reinforcing portion which is impregnated and solidified in the fastener tape body is 20 to 115 μm. 
     
     
         6 . The fastener tape according to  claim 1 , wherein in the reinforcing portion, a ratio d/D is 0.14 to 0.83, in which d is a thickness of a fraction which is impregnated and solidified in the fastener tape body, and D is a thickness of a reinforcing sheet that is a material of the reinforcing portion. 
     
     
         7 . The fastener tape according to  claim 1 , further comprising a separable insertion mechanism on the reinforcing portion.
