Abstract:

A reinforcing glass fiber for rubber articles which is excellent in the impregnation of glass fiber strands with an RFL treatment, is reduced in the swell of coats with the PFL treatment, has excellent appearance and physical performance, and little causes scatter of quality; and a process for the production of the glass fiber. The reinforcing glass fiber can be produced by impregnating a glass fiber strand composed of 200 to 2000 glass filaments not in an integrated state but in a separate state with an RFL treatment containing a rubber latex and a water-soluble resorcinol -formaldehyde condensate as the main components, setting the RFL treatment impregnated into the strand to form a coat, first-twisting the thus obtained coated glass fiber to form a first-twist yarn, and second-twisting at least two first-twist yarns thus obtained in the direction opposite to that of the first twisting.
