    (54) Method of treating fibrous materials


    (57) A method of treating fibrous materials comprises applying a composition comprising as sole amine containing organosilicon compound the reaction product of an organopolysiloxane having

    groups with one or more monoepoxides. X denotes a monovalent C, -8 hydrocarbon group, R is an alkylene group, R' is H or a group of the formula RZ, Z being NHX, NH2, NHRNH2 or NHRNHX. No more than 10% of all amine groups may be primary amine groups. The composition is preferably applied as an emulsion. Fibres thus treated are soft and show less yellowing than the prior art.
