Abstract
An improved textile forming size for glass fibers utilized in the preparation of rubber coated glass fiber tire cord is described in which a starch based forming size has incorporated therein a non-inoic wetting agent, a silane coupling agent and a paraffinic or microcrystalline wax. The use of this forming size on glass fibers which are subsequently coated with elastomer for use as tire cord results in a tire cord having improved flex fatigue properties.
