Abstract
Abstract Aqueous compositions for the coating of glass fibers used particularly for textiles, a method of applying these compositions to the fibers, and the fibers themselves are disclosed. The aqueous compositions comprise at least one starch, a non-ionic lubricant, a cationic lubricant, emulsifier and at least one organo-silane from the group made up of the organo-silanes comprising an organic chain of the polyazamide type and of the organo-silanes whose organic chain contains at least one phenyl radical and at least one secondary or tertiary amine group.
