Definitions

• the subject of the invention is aqueous emulsions with a total solids content of to 40 percent by weight, characterised in that they contain the following in relation to the dry weight of the components (a) to (d):
• Possible components (a) are especially methylolaminotriazines esterified with higher fatty acids and/ or etherified with higher alcohols.
• derivatives of formoguanamine, acetoguanamine or benzoguanamine, but preferably of melamine, are for example used.
• Methylol groups of these compounds are esterified with higher fatty acids which contain at least 12 carbon atoms or are etherified with higher alcohols, that is to say alkanols containing at least 12 carbon atoms.
• the triazine compounds advantageously further contain methylol groups etherified with alkanols containing at most 4 carbon atoms, such as butanol, isopropanol or especially methanol.
• alkanols containing at most 4 carbon atoms such as butanol, isopropanol or especially methanol.
• the methylol groups present it is advisable for the methylol groups present to be further substituted in the indicated manner to the extent of at least 75%, in particular to be esterified with higher fatty acids or etherified with higher alcohols to the extent of 15 to 50%.
• higher acyl residues those of fatty acids with 12 to 24 carbon atoms should above all be mentioned, for example lauric, myristic, palmitic or stearic acid, and the residues do not have to be all the same.
• esters obtainable from methylolmelamineethers and stearic acid are particularly suitable, especially those which are obtained by reaction of highly methylated methylolmelamines with stearic acid, and so-called technical stearic acid of commercially available quality can also be used with practically the same result as pure stearic acid.
• a higher alcohol with 12 to 24 carbon atoms lauryl, myristyl, palmityl, stearyl or arachyl alcohol may be mentioned, and here again the residues do not all have to be the same, and technical fatty alcohols can again be used.
• the molecular chain of the higher alcohol can optionally also be interrupted by nitrogen atoms, that is to say instead of the actual alcohols it is for example also possible to use fatty acid methylolamides as etherifying agents for the manufacture of the component (a).
• Possible fatty acids are here the same as those mentioned for the acylation.
• Stearic acid methylolamide for example represents such a use.
• the fatty acid amides which are also suitable for the reaction with a methylolaminotriazine are derived from the same fatty acids as those used for the etherification.
• substance(b) it is possible to use the known waxy agents for conferring hydrophobic properties, such as for example beeswax and especially parafiins of melting point advantageously between about 45 and C.
• a waxy substance there is as a rule understood a hydrophobic fusible substance which can be plastically deformed and possesses a smooth surface which can be scratched.
• Component (c) as a rule consists of reaction products of ethylene oxide with organic compounds which possess at least one reactive hydrogen atom and a hydrophobic residue.
• reaction products of polyethylene glycol compounds of the indicated nature can also be used.
• Particular interest attaches to water-soluble polyethylene glycol compounds which per molecule contain 8 to 100, preferably 9 to 80, but especially 12 to 60 and even only 20 to 50 CH -CH O-- groups.
• component (0) contains, as the hydrophobic residue, at least one residue which has been produced by splitting off a hydrogen atom from a hydroxyl, mercapto, carboxyl, carboxyamido or amino group of an organic compound.
• the organic compound with the reactive hydrogen atom and the hydrophobic residue thus for example is an alcohol, a thioalcohol, a carboxylic acid, a carboxylic acid amide or an amine.
• Alkylphenols, especially a tributylphenol, are particularly suitable.
• Particularly valuable components (c) are the watersoluble polyethylene glycol compounds which per molecule contain 20 to 50 CH CH O- groups and at least one phenoxy residue which is optionally substituted by alkyl groups.
• a Water-soluble polyethylene glycol compound which per molecule contains 30 CH CH -O- groups and a tributylphenoxy residue has proved particularly advantageous.
• the sodium, potassium or especially calcium salts of a dodecylbenzenesulphonic acid have here proved to be of particular interest.
• the alkyl residue, or the dodecyl residue can be branched or unbranched.
• the residues in the case of dodecylbenzenesulphonic acid are either n-dodecyl residues or branched residues which are obtained by reaction of tetrapropylene with benzene and subsequent sulphonation and neutralisation.
• the components (a) to (d) are used in such a way that the aqueous emulsions contain, relative to the dry Weight of components (a) to (d), 34 to 48% of component (a), 48 to 58% of component (b), 1.8 to 11% of component (c) and 1.3 to 9% component (d), with the content of components (a) and (b) together amounting to 85 to 96% and of components (c) and (d) together amounting to 4.5 to 15%, relative to the dry weight.
• the aqueous emulsions are mobile to 35% strength) or viscous (35 to 40% strength).
• the emulsion is diluted with cold or warm water and a curing catalyst is added so that the resulting bath shows a solids content of 1 to 18 percent by weight.
• curing catalyst for the methylol compound (a) it is possible to use the known acid or potentially acid aminoplastic curing agents, for example ammonium salts of strong acids such as ammonium thiocyanate or ammonium chloride, zinc nitrate, zinc chloride, zinc fluoborate, magnesium chloride, hydrochloric acid, phosphoric acid or formic acid. Aluminium salts, for example aluminium chloride or especially aluminium sulfate, prove particularly advantageous.
• the curing catalyst is appropriately used in amounts of l to 5% relative to the dry weight of the treatment bath.
• the baths manufactured in this way by dilution of the aqueous emulsions and by addition of a curing catalyst serve for the production of a wash-fast, water-repellent finish on fibre materials, the fibre material being treated with these aqueous baths, which now show a solids content of 1 to 18 percent by weight.
• the treatment of the fibre material for example cotton of fibres of regenerated cellulose
• the baths of the indicated composition can take place at room temperature or slightly elevated temperature, for example to C., using the customary known devices, appropriately by impregnation on a padder.
• the weight increase is advantageously 60 to 100%.
• the finishes obtainable according to the present process impart good water repellency to the fibre materials and are wash-fast.

• component (c) which acts as emulsifier
• a homogeneous melt of m g. of a condensation product M (:component (a)), the manufacture of which is described below, and of p g. of parafiin ( component (b)), warmed to about 105 C., is now poured into this aqueous emulsifier-sulphonate solution, and stirred at increasing speed of rotation until an emulsion is formed, care being taken, through regulating the external heating, that the emulsion does not start to boil.
• An emulsion is produced, which is thereafter diluted with 10 g. of water at above 80 C., at a low speed of stirring. This somewhat more dilute solution is new again stirred at high speed of rotation and then again stirred at low speed of rotation with 11 to 25 g.
