PROBLEM TO BE SOLVED: To provide a rubber composition/fiber composite improved in initial adhesion between the rubber composition and the fiber, adhesion after thermal degradation, and dynamic viscoelasticity, to provide an adhesive auxiliary for obtaining the rubber composition/fiber composite, and to provide an RFL adhesive treatment liquid.SOLUTION: There are provided: an adhesive auxiliary comprising a vinyl chloride/carboxylic acid vinyl ester copolymer latex which contains 0.2-10.0 pts.wt. compound comprising a sulfonate salt or a sulfate salt and 0.05-3.0 pts.wt. higher fatty acid salt based on 100 pts.wt. vinyl chloride/carboxylic acid vinyl ester copolymer having a carboxylic acid vinyl ester content of 0.5-20 wt.%, and has a ≤0.3 μm average particle diameter and a pH of 3-9; an RFL adhesive treatment liquid using the adhesive auxiliary; and a rubber composition/fiber composite using the RFL adhesive treatment liquid. |
