ABSTRACT:
Adhesive composition for adhering rubber and fiber which make synthetic fibers highly adhesive to rubber even when a reduced amount of the composition is applied to the fibers; rubber-reinforcing synthetic fibers coated with the adhesive composition to have improved adhesiveness to rubber while retaining the intrinsic characteristics of the synthetic fibers themselves; and fiber-reinforced rubber structures where the rubber has been reinforced by the rubber-reinforcing synthetic fibers. The adhesive composition contains, adhesive matrix and a silicate compound, the silicate compound comprising silicon and magnesium at a ratio by weight of silicon/magnesium of from 1/0.1 to 1/1.0. Preferably, a 1% aqueous dispersion of the silicate compound has a transmittance of about 50% or more and/or a 2% aqueous dispersion of the silicate compound has a thixotropy index of from about 2.0 to 10.0. The silicate compound is preferably a smectite.
