Abstract: Amines, ammonium bases, or salts thereof, having at least one aliphatic or cycloaliphatic radicle with at least eight carbon atoms and at least one alcoholic hydroxyl group, but no acylated amino group, are used in preparing aqueous emulsions of oiling or impregnating substances, such as paraffin wax and olive oil, or other materials, for use in the treatment of fibrous materials such as textiles and leather.  In examples: (1) an aqueous emulsion containing N-oxyethyl-N-octodecylamine and ethyl alcohol is used for softening viscose silk, (2) an emulsion of tetrahydronaphthalene, prepared with the aid of the hydrochloride of N-oxyethyl-N-octodecylamine is used for cleaning textiles, (3) an emulsion obtained from olive oil, glue, and N-pentadecyl-N-oxyethylamine lactate is used for oiling textiles, and (4) trichlorethylene is emulsified with the aid (a) of a solution of the hydrochlorides of a mixture of tertiary amines obtained by treating diethanolamine with the sulphuric esters of a mixture of alcohols obtained by catalytic reduction of coco-nut oil, or (b) of a mixture of secondary and tertiary amines made by treating the sulphuric esters of a mixture of cycloaliphatic alcohols obtained from raw commercial naphthenic acid according to Specification 359,116 with monoethanolamine; the emulsions are used for cleaning or degreasing textiles.ALSO:Aqueous solutions containing amines, ammonium bases or salts thereof, having at least one aliphatic or cyclo-aliphatic radicle with at least eight carbon atoms and at least one alcoholic hydroxyl group, but no acylated amino group, are used as wetting or softening agents in processes for the treatment of organic fibrous materials, such as textiles or leather.  Among the amines which may be used are the products obtained by treating mineral acid esters of higher fatty alcohols with ammonia or amines, or by introducing further alkyl or cycloalkyl groups into primary, secondary, or tertiary amines corresponding to the higher fatty alcohols.  The salts of the amines which may be employed include the hydrochlorides, sulphates, nitrates, acetates, lactates, and formates.  The solutions containing the amines, ammonium bases or their salts may be employed alone or in admixture with other agents, e.g. water-soluble salts of organic or inorganic acids, perborates, vegetable mucilages, soluble gums, glue, or solvents of different kinds, including cyclohexanone, trichlorethylene, benzyl alcohol, or ethylene glycol monocresyl ether (made from ethylene chlorhydrin and the sodium salt of the commercial mixture of cresols).  The amines, ammonium bases, or salts may also be used for emulsifying, oiling, or impregnating substances, such as paraffin wax or olive oil in water, the emulsions obtained being used as oiling and impregnating agents in the textile industry. In examples, (1) viscose silk or cotton fabrics are softened by treating with an aqueous solution of N-octodecyl-N-oxyethylamine acetate or of the sodium salt of N-dodecyl-N-oxyethylaminoacetic acid (made by heating equimolecular proportions of N-dodecyl-N-oxyethylamine and chloracetic acid with aqueous caustic soda), (2) woollen goods are dyed evenly in a boiling bath containing Anthraquinone blue SR extra, Tartrazine, Naphthol red S, sulphuric acid, and N-oxyoctodecyl-N-dimethylamine sulphate (obtained by the action of dimethylamine on the mono-sulphuric ester of octodecandiol), or a mixture of N-mono- and di-oxyethyl-N-heptadecylamines, (3) textiles are wetted out by treating with an aqueous solution of the hydrochloride of N-oxyethyl-N-dodecylamine (made from monoethanolamine and dodecyl sulphuric ester), (4) viscose silk is softened by treating with an aqueous emulsion prepared from N-oxyethyl-N-octodecylamine and ethyl alcohol, (5) oil stains on textiles are removed by treatment with an emulsion of tetrahydronaphthalene in an aqueous solution of the hydrochloride of N-oxyethyl-N-octodecylamine (obtained from monoethanolamine and the sulphuric ester of octodecyl alcohol by the process of Specification 369,614), (6) textiles are oiled with an emulsion obtained from olive oil, glue, and the lactate of N-pentadecyl-N-oxyethylamine (made from ethylene oxide and pentadecylamine), (7) textiles are wetted out by treatment with a solution of the acetates of the mixture of tertiary amines containing a cyclohexyl and an oxypropyl radicle and radicles corresponding to the fatty acids of coco nut oil obtained by treating the phosphoric esters of the mixture of alcohols prepared by catalytic reduction of coco-fat with N-cyclohexyl-N-propanolamine by the process of Specification 369,614, (8) trichlorethylene is emulsified in an aqueous solution of the hydrochlorides of a mixture of tertiary amines obtained by treating diethanolamine with the sulphuric esters of a mixture of alcohols obtained by catalytic reduction of coco nut oil; the emulsions have a high washing power for removing stains from textiles, (9) a cotton fabric is treated with a magnesium sulphate solution containing the acetate of N-dodecyl-N-oxyethylamine (made from dodecylamine and ethylene glycol chlorhydrin), (10) a solution of the sulphate of dimethyloxyethyldodecyl ammonium hydroxide (made from dimethylamine and N-oxyethyl-N-dodecylamine) is used for removing stains from textiles, (11) N-oxyethyl-N-dodecylamine is added to a carbonizing bath for woollen goods, (12) the wool and cotton in a mixed fabric is dyed equally in a bath containing Fast light yellow 3 G or Sorbine red BB, sulphuric acid, Glauber's salt, and a mixture of mono- and dioxyethyl-N-heptadecylamines (obtained by the action of ethylene oxide on heptadecylamine), and (13) an emulsion of trichlorethylene made with the aid of the mixture of secondary and tertiary amines obtained by treating the sulphuric esters of a mixture of cycloaliphatic alcohols obtained from raw commercial naphthenic acid according to Specification 359,116 with monoethanolamine is used for degreasing textiles. Specifications 294,890, 307,948, [both in Class 15 (ii), Dyeing, Processes &c. for], and 328,675, [Class 2 (iii), Dyes &c.], also are referred to.
