    Abstract: CELLULOSIC TEXTILES ARE TREATED WITH AN ESTER WHICH CONTAINS, ON AVERAGE, AT LEAST TWO MERCAPTAN GROUPS PER MOLECULE, AND WITH AN AMINOPLAST WHICH IS FREE FROM ETHYLENIC UNSATURATION, AND THE AMINOPLAST IS CURED. THE TREATED TEXTILES HAVE ENHANCED DIMENSIONAL STABILITY, RESISTANCE OF CREASING, AND MAY HAVE PERMANENT CREASES IMPARTED, WHILST HAVING A FULLER, SOFTER HANDLE AND INCREASED TEAR STRENGTH COMPARED TO CELLULOSIC TEXTILES TREATED WITH THE AMINOPLAST ALONE. TYPICALLY, THE ESTER IS PREPARED BY THE REACTION OF (A) A COMPOUND CONTAINING AT LEAST TWO CARBOXYLIC ACID GROUPS, (B) A COMPOUND CONTAINING AT LEAST TWO ALCOHOLIC HYDROXYL GROUPS AND, OPTIONALLY, (C) A COMPOUND CONTAINING NOT MORE THAN ONE CARBOXYLIC ACID GROUP OR ALCOHOLIC HYDROXYL GROUP, ESPECIALLY A MONOMERCAPTOMONOCARBOXYLIC ACID OR A MONOMERCAPTOMONOHYDRIC ALCOHOL.

    Abstract: Flame retardants for cellulosic fabrics, especially polyester blends, comprise a limited phosphine oxide class of N-methylol propionamides, particularly N-methylol-3(dimethylphosphinyl)propionamide, closely related structurally to N-methylol-3-(dimethyl phosphono)propionamide, but markedly more effective as a flame retardant.

    Abstract: The use of 4,4'-azobis(4-cyanovaleric acid) and its salts as water-soluble free radical initiators, and simultaneously or alternatively the addition of catalytic amounts of tetrakis(hydroxymethyl)phosphonium sulfate as a polymerization accelerator, in the sequential polymerization and acid-catalyzed grafting of N-methylolacrylamide on cotton textiles from a single treating bath in a padding and two-stage heat curing operation, is disclosed. The cotton textiles as treated are free from discoloration and excessive tendering produced by peroxide-type initiators, and these textiles exhibit increased smooth drying performance, abrasion resistance and strength relative to textiles treated conventionally with dimethyloldihydroxyethyleneurea to comparable wrinkle recovery angles.

    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: An aluminum acetate salt solution containing sodium and chloride ions is prepared by reaction of aqueous aluminum chloride and sodium acetate. It is suitable for use as a catalyst in the treatment of cellulosic-containing textiles with formaldehyde or a formaldehyde-amide adduct crosslinking agent to produce durable press properties in the finished material. There is no discoloration in the thus-treated fabric which also exhibits greater strength than is normally present in fabric treated to the same level of wrinkle resistance with an aluminum salt catalyst.
