Abstract

Abstract A process and a composition useful for imparting abrasion resistance, resistance to frosting, wrinkle resistance, crease retention, wash-and-wear characteristics, durable press characteristics, and permanent press characteristics to cellulosic textile materials and to improve the wet strength, water absorption, and other properties of cellulosic paper. The process comprises; (a) impregnating the textile material or the paper with an aqueous aminoplast system comprising at least one aminoplast and at least one member of a latter recited first group; and (b) curing the aminoplast on the cellulosic material by; (i) irradiation; or (ii) by heating in the presence of an acidic catalyst. The composition comprises an aqueous aminoplast system admixed with an effective amount of a member of a first group consisting of: WHERE; (A) X IS 0 OR 1; (B) R1 is hydrogen or an alkyl group having about 1-5 carbon atoms; (c) R2 is hydrogen or an alkyl group having about 1-5 carbon atoms; (d) R3 is hydrogen, an alkyl group having about 1-5 carbon atoms, or -SO3 ; (c) R4 is hydrogen, an alkyl group having about 1-8 carbon atoms, CH2CH2OH; or -C6H5; (f) R5 is hydrogen, an alkyl group having about 1-8 carbon atoms, -CH2CH2OH; -C6H5; or -CH2OH; and (g) A is a member selected from a second group consisting of; (i) -NC5H10; (ii) -NC4H8O; and (iii) -NC4H8.
