<p>This invention relates to a subcoat composition for bonding synthetic fibers to natural or synthetic rubber. This invention more specifically discloses a subcoat which is particularly useful for adhering synthetic fibers to rubber which is comprised of (a) 1 % to 4 % by weight oxazoline polymer, (b) 0 % to 4 % alkylene glycol monoether and (c) 92 % to 99 % water. The present invention further discloses a process for adhering synthetic textile fibers to sulfur vulcanizable rubbers comprising the steps of (I) immersing said fibers in an aqueous dispersion which is comprised of (a) 1 % to 4 % by weight oxazoline polymer, (b) 0 % to 4 % alkylene glycol monoether and (c) 92 % to 99 % water to produce coated fibers; (II) drying the coated fibers to produce subcoated fibers; (III) subjecting the subcoated fibers to an RFL adhesive dip to produce dipped fibers; (IV) drying the dipped fibers to produce dried dipped fibers; (V) placing the dried dipped fibers in contact with a sulfur vulcanizable rubber; and (VI) curing the sulfur vulcanizable rubber while it is in contact with the dried dipped fibers.</p> |
