Abstract
A simple and economical one-step process for felt-proofing and dimensionally stabilizing textiles, particularly textiles based on keratinous fibers is disclosed. In the process, the textiles are treated with aqueous baths which contain salts of sulfurous acid or pyrosulphites as reducing agents and polyurethanes which contain onium groups.
