Title: Process for treating textile materials
IPC: C11D1/00
Filed: 1962-10-25
Abstract: Compounds suitable for use in the treatment of textile materials are prepared by reacting esters of fatty acids containing 12-20 carbon atoms with monohydric alcohols containing 4-12 carbon atoms and/or polyhydric alcohols containing 2-6 hydroxyl groups with salts or quaternization products of amide-amines obtained by the reaction of 1-1.7 mol. of a carboxylic acid containing 6-20 carbon atoms or a functional derivative thereof with 1 mol. of a diamine of the formula: <FORM:0962421/C1/1> in which R1 and R2 which may be the same or different are alkyl radicals containing 1-8 carbon atoms and n is a whole number of 2-4, the amount of diamine employed being not more than 8% by weight of the reaction product. The esters used may be those of tallow, coconut fat, olive oil, castor oil, palm kernel oil, lanolin, sperm oil or wool fat or the esters obtained by the reaction of polyglycerol with fatty acids containing 12-20 carbon atoms or by the reaction of polyglycerol or sorbitol with fats, e.g. beef tallow or coconut fat, in the presence of alkali metal hydroxides.  Suitable salts of the amide-amines are those formed by reaction with sulphuric, phosphoric, formic, acetic or lactic acid and the quaternization products may be those formed by reaction with dimethyl or diethyl sulphate, ethyl bromide, benzyl chloride, epichlorhydrin, chloroacetamide, or N-methylol chloracetamide.  Salts or quaternization products of amide-amines prepared in the presence of polyglycerol are preferably utilized. The reaction of the esters with the salts or quaternization products of the amide-amines is preferably carried out by heating for 1-2 hours at 110 DEG -130 DEG C.ALSO:Textile materials are softened and rendered antistatic by treating them with reaction products prepared from esters of fatty acids containing 12-20 carbon atoms with monohydric alcohols containing 4-12 carbon atoms and/or polyhydric alcohols containing 2-6 hydroxyl groups and salts or quaternization products of amide-amines obtained by the reaction of 1-1.7 mol of a carboxylic acid containing 6-20 carbon atoms or a functional derivative thereof with 1 mol of a diamine of the formula <FORM:0962421/D1-D2/1> in which R1 and R2 which may be the same or different are alkyl radicals containing 1-8 carbon atoms and n is a whole number of 2-4, the amount of diamine employed being not more than 8% by weight of the reaction product.  The esters used in the formation of the reaction products may be tallow, coconut fat, olive oil, castor oil, palm kernel oil, lanolin, sperm oil, wool fat or the esters obtained by the reaction of polyglycerol with fatty acids containing 12-20 carbon atoms or by the reaction of polyglycerol or sorbitol with fats e.g. beef tallow or coconut fat, in the presence of alkali metal hydroxides.  The salts of the amide-amines may be these formed by reaction with sulphuric, phosphoric, formic, acetic or lactic acid and the quaternization products may be those formed by reaction with dimethyl or diethyl sulphate, ethyl bromide, benzylchloride, epichlorhydrin, chloracetamide or N-methylol chloracetamide.  The reaction products may be applied to the textile materials from solutions in water, aliphatic or aromatic organic solvents or mixtures thereof in a concentraof 2-20 g/litre at 30 DEG -60 DEG C. and the materials may then be dried at 70 DEG -90 DEG C.  The treating compositions may also contain paraffin or wax emulsions containing alumminium or zirconium salts, water soluble urea or melamine formaldehyde precondensates, polyacrylates, fatty alcohols or their alkoxylation products, mineral oils, mineral fats, wetting agents or optical brighteners.  Fibres or threads of wool, cotton, regenerated cellulose, cellulose acetate, polyurethanes, polyamides, polyesters, polyolefines, polyacrylonitrile and/or mixed polymers of acrylonitrile with other vinyl compounds, or fabrics or knitted goods, e.g. socks or stockings, produced therefrom may be treated. The process is applicable to yarns in vats and packing machines, on conical cross-wound bobbins and on piece goods on reels or on a foulard.
