Title: Textile materials for reinforcing rubber articles
IPC: C08J5/06
Filed: 1956-04-23
Abstract: Natural or synthetic rubber articles are reinforced with textile fibres, yarns, cords or fabrics which contain a nitroso-phenol in which the nitroso group is directly attached to a nuclear carbon atom.  The nitroso-phenol may be added to a viscose spinning solution.  Among the nitroso phenols specified are dinitrosophenol, paranitrosophenol, 2-nitroso-1-naphthol, ortho - nitroso - meta - cresol, nitroso - 4 - tertiary butyl - meta - cresol, nitrosothymol, 4-nitro-socarvacrol, trinitrosophloroglucinol and 2,4-dihydroxy-3-nitroso-azobenzene.ALSO:In the reinforcement of natural or synthetic rubber articles by textile fibres, yarns, cords or fabrics, the textile material is treated, prior to application of the rubber, with a nitroso phenol in which the nitroso group is directly attached to a nuclear carbon atom.  The textile material may be of nylon or regenerated cellulose.  Among the treating compounds specified are para-nitrosophenol, 2-nitroso-1-naphthol, orthonitroso - meta - cresol, nitroso - 4 - tertiary - butyl - meta-cresol, nitrosothymol, 4-nitrosocarvacrol, trinitrosophloroglucinol and 2,4-dihydroxy-3-nitroso-azobenzene.  The nitroso-phenol may be applied in aqueous solution, or dispersion, as an emulsion or in organic solution.  The treated material may be coated with or embedded in rubber stock which may contain vulcanizing agents, accelerators or fillers.  In examples, nylon and rayon tyre cords are treated with aqueous dispersion of dinitrosoresorcinol.
