DEFINITION

Classification: 8/182

(under subclass 181) Processes wherein the cellulose textiles or fibers are chemically modified with a condensation product of an organic nitrogenous compound and an aldehyde or ketone or wherein, in addition to the chemical modification of the cellulose textiles or fibers by the nitrogen-containing organic compound, there is a previous, simultaneous or sucessive treatment with an aldehyde or ketone which can form a nitrogenous- aldehydo- or keto-condensate in situ with the nitrogen-containing organic compound.
