Adhesive agent composition for organic fiber and method of treating organic fiber

Abstract

An object of the present invention is to provide an adhesive agent composition for an organic fiber, the adhesive agent composition hardly causing precipitation or cohesion and having stable adhesive force. The present invention provides an adhesive agent composition for an organic fiber, the adhesive agent composition including epoxy resin and a water soluble curing agent, and also provides to a method of treating an organic fiber, the method including the steps of: (i) treating the organic fiber with the adhesive agent composition as a first treating agent; and (ii) treating the organic fiber, having been treated with the first treating agent, with a second treating agent containing a resorcin-formalin-rubber latex (RFL).

1 . An adhesive agent composition for an organic fiber,
 the adhesive agent composition comprising epoxy resin and a water soluble curing agent.   
     
     
         2 . The adhesive agent composition according to  claim 1 , wherein the water soluble curing agent is an imidazole compound or a carboxylate compound. 
     
     
         3 . The adhesive agent composition according to  claim 1 , wherein the organic fiber is a polyester fiber or an aramid fiber. 
     
     
         4 . A method of treating an organic fiber,
 the method comprising the steps of:   (i) treating the organic fiber with the adhesive agent composition according to  claim 1  as a first treating agent; and   (ii) treating the organic fiber, having been treated with the first treating agent, with a second treating agent containing a resorcin-formalin-rubber latex (RFL).   
     
     
         5 . The method according to  claim 4 , wherein the organic fiber is a polyester fiber or an aramid fiber. 
     
     
         6 . An organic fiber treated by the method according to  claim 4 . 
     
     
         7 . A tire, hose, or belt using the organic fiber according to  claim 6 .
