Title: Treatment of keratinous fibres and fabrics
IPC: D06M15/273
Filed: 1969-11-14
Abstract: 1311090 Treating keratinous materials CIBA-GEIGY (UK) Ltd 14 Oct 1970 [14 Nov 1969] 55992/69 Heading D1P A process for imparting durable press and shrink resist properties to keratinous material, e.g. wool, comprises treating the material with an ester containing at least two mercaptan groups per molecule and which is the reaction product of a) at least one monomercaptomonocarboxylic acid or monomercaptomonohydric alcohol, b) at least one compound containing, per molecule, at least two alcoholic hydroxyl groups or at least one 1:2 epoxide group and c) at least one compound containing, per molecule at least two carboxylic acid groups or an anhydride thereof, the ester subsequently curing on the material. The keratinous material to be treated may include all forms of fibres, fabrics and garments, made therefrom, of wool or blends of wool with synthetic or cellulosic fibres containing at least 30% by weight of keratinous fibres. Esters preferred for use in the process contain, directly attached to carbon atoms, an average 'n' groups of fomula per molecule where "a" and "b" are each zero or one, but differ from each other, "n" is an integer having a value of from 3 to 6, R<SP>1</SP> is a divalent organic radical directly linked through a carbon atom to the indicated -O- or -CO- units and R is a divalent organic radical. Examples are given in the Specification. The ester may be applied by padding, dipping or spraying in the form of an aqueous dispersion or emulsion, but preferably as a solution in an organic solvent, e.g. an alcohol, lower betane, benzene or halogenated hydrocarbon. A protective colloid such as sodium carboxymethylcellulose may be present if an aqueous emulsion of the ester is employed. The curing of the ester is preferably accelerated by use of a catalyst, e.g. organic or inorganic bases such as primary or secondary amines or lower alkanolamines, sodium hydroxide or ammonia, peroxides and hydroperoxides, sulphur, mercaptobenzothiazoles, dithiocarbamates, thiuran sulphides, thioureas di-alkyl, -cycloalkyl or -aralkyl disulphides, alkyl xanthogen disulphides and alkyl xanthates, the reaction being carried out at a pH of between 7.5 and 12, using 0.1% to 20% of catalyst by weight based on the weight of the polymercaptan ester. Elevated temperatures in the range of 30 to 180C may be used or the material may be treated with steam especially when flat-setting is also carried out. Agents which block the thiol groups of the wool, e.g. aldehydes may be applied to creased or pleated garments after the polymercaptan has cured. The compositions used in the process may also contain other agents, e.g. setting agents such as monoethanol amine sesquisulphite, swelling agents such as urea, water repellent agents such as paraffin wax and fluorescent brightening agents.
