PROBLEM TO BE SOLVED: To provide an adhesion adjuvant for improving the initial adhesion force between a rubber composition and a fiber, adhesive force within a high-temperature atmosphere, post-thermal-degradation adhesive force, and post-thermal-flexural-fatigue adhesive force; an adhesive treatment solution; and a rubber-fiber composite.SOLUTION: The provided adhesion adjuvant, adhesive treatment solution for a rubber composition-fiber composite, and rubber composition-fiber composite each include a vinyl chloride polymer latex which includes, with respect to 100 pts.wt. of a core segment consisting of a vinyl chloride polymer, 2-100 pts.wt. of a shell segment consisting of polymers such as a (meth)acrylic acid-based polymer, vinyl propionate-based polymer, allyl glycidyl ether-based polymer, etc., 1.0-5.0 pts.wt. of an organic compound possessing a sulfonate or sulfuric acid ester salt, 0.05-2.5 pts.wt. of a higher fatty acid salt and 10 or less pts.wt. of an emulsifier, and the average particle diameter of the vinyl chloride polymer is 0.30 μm or less. |
