Abstract

Fiber for reinforcing rubber products, which comprises glass fiber coated with a coating film formed by a treating agent comprising a water-soluble condensate of resorcinol and formaldehyde, a latex of a solid acrylonitrile/butadiene copolymer and a latex of a liquid acrylonitrile/butadiene copolymer.

Claims

1. Fiber for reinforcing rubber products, which comprises glass fiber coated with a coating film formed by a treating agent comprising a water-soluble condensate of resorcinol and formaldehyde, a latex of a solid acrylonitrile/butadiene copolymer and a latex of a liquid acrylonitrile/butadiene copolymer.

2. The fiber for reinforcing rubber products according to claim 1, wherein the latex of a solid acrylonitrile/butadiene copolymer is a latex of a self-crosslinking acrylonitrile/butadiene copolymer.

3. The fiber for reinforcing rubber products according to claim 1, wherein the latex of a solid acrylonitrile/butadiene copolymer is a soap-free acrylonitrile/butadiene copolymer latex.

4. The fiber for reinforcing rubber products according to claim 1, wherein the treating agent further contains at least one component selected from the group consisting of a latex of a halogen-containing polymer, a latex of an acrylate polymer and an epoxy resin emulsion.

5. The fiber for reinforcing rubber products according to claim 1, wherein the glass fiber coated with the coating film formed by the above treating agent, is further coated with a second coating film formed by a second treating agent comprising a rubber, a vulcanizing agent and an inorganic filler.
