Abstract
Process for making fibrous material water repellent by treating it with an aqueous bath containing (A) an emulsified organo polysiloxane with at least 2 hydroxyl groups optionally modified in a manner able to cross-link, (B) a non-ionic emulsion of poly silicic acid ester, (C) a reaction product which has been obtained by reaction of an organic compound containing at least one halohydrin and/or epoxy group with an organic compound containing hydrogen atoms bound to nitrogen, which in form of its salt is water-soluble or at least water-dispersible. The treated material is dried and optionally cured.
