PROCESS FOR PRODUCING A MODIFIED FIBROUS MATERIAL USEFUL FOR REINFORCING RUBBER ARTICLES

摘要

A modified fibrous material useful as a reinforcing matrerial for rubber articles is produced by applying a cold plasma treatment to a fibrous material comprising at least one type of synthetic fibers selected from aromatic polyamide fibers and polyester fibers under a reduced pressure; by applying an ion-plating treatment with a polyamide vapor to the resultant cold plasma-treated fibrous material under a reduced pressure; by impregnating the resultant ion-plated fibrous material with an RFL adhesive composition comprising a resorcinol-formaldehyde precondensation product and a rubber latex; and by curing the adhesive composition in the fibrous material.
