ABSTRACT:
The invention is a process whereby a fibrous cellulosic textile material is rendered wrinkle resistant by impregnating the material with an aqueous mixture of urea and at least one phosphoric acid, wherein the mole ratio of urea to phosphoric acid is about 4:1 to 8:1, to deposit thereon about 7.0-35% by weight of urea, and about 3.0-9.0% by weight of the phosphoric acid, based on the weight of the untreated material; heating the treated material to obtain a phosphorylated material; contacting the phosphorylated material with an aqueous solution of cyanamide to deposit thereon about 0.75-13.5% by weight of cyanamide, based on the weight of the phosphorylated material; and, heating the treated material to impart wrinkle resistance thereto.
