METHOD FOR TREATING POLYESTER FIBER

摘要

PURPOSE: To provide a treating method not causing gum up phenomenon on an adhesive treatment process, having same adhesive performance as adhesion by conventional method or higher adhesive performance than adhesion by the method in adhesion between polyester fiber and rubber. CONSTITUTION: This method for treating a polyester fiber is to treat the polyester fiber with the first treating agent containing a blocked polyisocyanate compound and a rubber latex and successively treating the second treating agent containing a resorcin-formalin-rubber latex (RFL), a blocked polyisocyanate compound and an anionic surfactant in an amount of 0.01-0.15wt.% based on total solid content of the both compounds.
