Abstract: Zwitterions are employed as catalysts in a chemical finishing process to treat cellulosic textiles with crosslinking agents and produce easy-care properties in the finished materials. The process comprises treatment of the textile material, such as cotton fabric, by impregnating it with a solution containing a cellulose-crosslinking agent and, as catalyst a zwitterion, alone or in combination with a magnesium salt, drying and curing the fabric. Said finished fabrics are characterized by an unusual combination of useful, desirable properties--smooth-drying appearance, wrinkle resistance, serviceable strength, and inoffensive formaldehyde release.

Abstract: Tris(4-substitutedureidomethyl)phosphine oxides were prepared by the reaction of tris(hydroxymethyl)phosphine with substituted ureas.

Abstract: Salts of 1,3,5-triaza-7-phosphaadamantane can be utilized as catalysts for finishing cellulose-containing textile materials with methylol amide crosslinking agents to give products with improved wrinkle resistance and durable press properties. Inorganic, organic, and sulfonic acid salts, and mixed salt complexes of this new tricyclic phosphorus-containing compound provide effective catalysis in the chemical reactions needed for these finishing treatments. Salts of the corresponding phosphorus oxide, 1,3,5-triaza-7-phosphaadamantane-7-oxide, provided even stronger catalysis in similar treatments.
