Abstract
Multi-filament reinforcing carbon yarn coated with a resorcinol-formaldehyde-latex (RFL) composition for use in reinforced rubber articles such as tires. The reinforcing yarn is prepared from a multi-filament carbon yarn having a limited denier of about 500-4,000, having a twist factor of the yarn of about 0-250, and having individual filaments which have a denier of 1.4-2.0. The reinforcing yarn is impregnated with RFL, so that the amount of coated RFL is at least about 10 weight percent based on the yarn. Treatment of the carbon filament yarn with an epoxy resin, prior to being subjected to impregnation with RFL, is also disclosed.
