Abstract: For washing textile materials having frictional electric properties, i.e. textiles containing cellulose acetate, cellulose ethers, superpolymers such as superpolyamides or superpolyesters, or vinyl polymers such as polyvinyl chloride, polyvinyl acetate, or polymers of acrylic acid derivatives, such as polyacrylic esters or polyacrylonitrile, use is made of aqueous baths containing, (1) an anionic or non-ionic washing agent and (2) a salt formed from equimolecular proportions of an anion-active compound and a cation-active onium compound other than a phosphonium compound. Specified anion-active compounds are the following or their water-soluble salts:-fatty acids, wax acids, naphthenic acids, resin acids, octyloxyacetic acid, hexadecylmercaptoacetic acid, C-alkylcresoxyacetic acids, sulphuric acid esters of dodecyl alcohol, oleyl alcohol or the mixture of alcohols obtained by reduction from coconut oil, the sulphuric acid ester of ethylene glycol mono-octyl ether, the mono- or di-sulphuric acid ester of glycerol monostearate, the phosphoric acid ester of decane diol monoacetate, butoxydecyl sulphuric acid ester, the hexyl thioether of octyl thiosulphuric acid ester, N - butyl - N - dodecylsulphamic acid, the sulphuric acid ester of b  - hydroxy - g  - octylcresoxypropane, octylphenoxyethane sulphuric acid ester, N - oleoyl - N - methyltaurine, the stearic acid ester of isethionic acid, N - cetylsulphonylsulphanilic acid, cyclohexyloxydecane sulphonic acid, octylphenyl-benzyl ether 41 - sulphonic acid, alkylbenzene sulphonic acids having 6-18 carbon atoms in the alkyl groups, alkylnaphthalene sulphonic acids, tetrahydronaphthalene sulphonic acids, 2 - isoalkylcresoxybenzoic - 5 - sulphonic acids having 5 - 11 carbon atoms in the alkyl groups, 1 - octylphenoxybenzene - 2, 4 - disulphonic acid, 1 - hexylphenoxy - 2 - acetylaminobenzene - 4 - sulphonic acid, sulphonated octylcresyl - benzyl ether, sulphonated cresoxyacetic acid dodecylamide dialkyl or dialkaryl disulphonimides and condensation products of higher carboxylic or sulphonic acid halides with proteins and like compounds.  The onium compound may be a quaternary ammonium or arsonium compound or a ternary sulphonium compound, specified compounds being trimethylbutyl ammonium bisulphate, trimethylhexyl ammonium chloride, trimethyldodecyl ammonium chloride, trimethyloctadecyl ammonium methosulphate dimethyldodecylbenzyl ammonium chloride, hexylpyridinium bisulphate, octadecylpyridinium chloride, hexylquinolinium chloride, octadecyloxycarbomethyl trimethyl ammonium chloride, dodecyloxycarbomethyl pyridinium methosulphate, naphthenoxycarbomethyl quinolinium chloride, abietyloxycarbomethyl quinolinium bromide, di(dodecyloxycarbomethyl) dimethyl ammonium methosulphate, octadecylaminocarbomethyl trimethyl ammonium chloride, octadecylanilinocarbomethyl pyridinium bisulphate, dodecyloxymethyl trimethyl ammonium chloride, octadecylthiomethyl triethyl ammonium bisulphate, octadecylcarbaminomethyl pyridinium chloride and octadecyloxycarbaminomethyl pyridinium methosulphate. Specified nonionic surface-active agents are the addition products of alkylene oxides, particularly ethylene oxide, with carboxylic or sulphonic acids, sulphonamides, alcohols, mercaptans or amines containing at least one radical of at least 6 carbon atoms. Specified salts of anion-active compounds and onium compounds are trimethylhexadecyl ammonium oleate, dimethylcyclohexyldodecyl ammonium oleate, dodecylpyridinium octyl sulphate, octadecylpyridinium alkyl sulphates containing 7-9 carbon atoms in the alkyl groups, the salt from chlorobenzylated dimethylaminoacetic acid dodecylamide and sodium octadecyl sulphate, and the salt from chlorobenzylated piperidinoacetic acid decylamide and sodium octadecenyl sulphate. In an example, a washing composition containing sodium oleyl sulphate or sodium alkyl sulphates having 12-18 carbon atoms in the alkyl groups is treated, either before it is spray-dried or in the form of a solution ready for use, with 2 per cent of a quaternary ammonium compound obtained by treating dimethylcyclohexylamine with dodecyl chloracetate; a polyamide textile material, washed with an aqueous solution of the product, develops no frictional electric charge after drying.ALSO:For washing textile materials having frictional electric properties, i.e. textiles containing cellulose acetate, cellulose ethers, superpolymers such as superpolyamides or superpolyesters, or vinyl polymers such as polyvinyl chloride, polyvinyl acetate, or polymers of acrylic acid derivatives, such as polyacrylic esters or polyacrylonitrile, use is made of aqueous baths containing (1) an anionic or non-ionic washing agent and (2) a salt formed from equimolecular proportions of an anionactive compound and a cation-active onium compound other than a phosphonium compound.
