Definitions

• This invention relates to a process for imparting a finish to fibrous materials, particularly textile materials and to compositions used in said process.
• Fibrous materials which can be advantageously finished by the aforesaid process include animal fibers such as wool or silk, semi-synthetic fibers such as cellulose acetate fibers, and fully synthetic fibers such as polyamide fibers, for example those derived from e-caprolactam or from adipic acid and hexamethylenediamine.
• the process has proved particularly advantageous when applied to cellulose-containing fibers such as linen or cotton and to fibers consisting of regenerated cellulose, such as viscose rayon or staple fiber.
• the triazine compounds employed in the present process comprise at least one 1,3,5-triazine ring. There is directly attached to the said triazine ring at least one halogen atom, and at least one substituent comprising a hydrocarbon radical containing more than 7 carbon atoms.
• the said hydrocarbon radical may be attached directly to the said ring but preferably is linked thereto through a bridge member containing or consisting of at least one hetero atom.
• the 1,3,5-triazine ring may be substituted in 2,4,6-position by (a) two halogen atoms and one substituent containing the hydrocarbon radical of more than 7 carbon atoms,
• Chlorotriazine compounds are preferably employed.
• the hydrocarbon radical preferably contains 12 to 22 carbon atoms. It may be branched or unbranched, saturated or unsaturated. In addition, it may be attached to the triazine ring through, for example, a sulfur atom, an oxygen atom or, preferably, through a nitrogen atom.
• the substituent corresponds, for example to the formula:
• R-ITI- in which R represents an aliphatic hydrocarbon radical containing at least 8 carbon atoms, and R an alkyl radical, which may also contain 8 or more carbon atoms, or a hydrogen atom.
• the monoor dichlorotriazine compounds containing the radical of such an aliphatic amine preferably correspond to the formula:
• R represents an aliphatic hydrocarbon radical, preferably an alkyl radical containing from 16 to 22 carbon atoms, R a hydrogen atom or an aliphatic hydrocarbon radical, and X a chlorine atom or an amino group, for example an H N-group or a group of the formula:
• atoms may alternatively be attached to the triazine ring through a bridge containing more than one hetero atom,
• R has the meaning assigned to it above, and A represents an alkylene radical, for example an ethylene or propylene radical, or a phenylene radical.
• the triazine compound contains, in addition to the halogen atom and the substituent containing the aliphatic hydrocarbon radical of 8 or more carbon atoms, a further substituent of any form, for example a hydroxyl group, an amino group, an alkoxy group, e.g. a methoxy group, an aryloxy group, e.g. a phenoxy group or an aryl-mercapto group, e.g. a phenyl-mercapto group, optionally further substituted in the aryl nuclei, or a radical attached directly to the triazine nucleus.
• a further substituent of any form for example a hydroxyl group, an amino group, an alkoxy group, e.g. a methoxy group, an aryloxy group, e.g. a phenoxy group or an aryl-mercapto group, e.g. a phenyl-mercapto group, optionally further substituted in the aryl nu

• the compounds of the Formula VIII in addition to the high molecular radical R may contain one, two or three further aliphatic hydrocarbon radicals and three, two or one hydrogen atoms bound to the nitrogen atoms.
• the monochloro- 1,3,5-triazine compounds may preferably correspond to the formula in which at least one and at the most two Rs represent alkyl radicals containing 16 to 22 carbon atoms and the remaining Rs represent hydrogen atoms.
• the triazine compounds employed in the present invention may be prepared, by methods known per se from the literature, from cyanuric halides, such as cyanuric bromide or preferably cyanuric chloride and alcohols, mercapta-ns, phenols, thiophenols or amines.
• cyanuric halides such as cyanuric bromide or preferably cyanuric chloride and alcohols, mercapta-ns, phenols, thiophenols or amines.
• Compounds containing hydrocarbon radicals directly attached to the triazine ring are obtained by reacting cyanuric halide with alkyl-, cycloalkyl-, aralkylor aryl-magnesium halides.
• Compounds of Formula II in which X represents a chlorine atom are preferably prepared by condensation of cyanuric chloride with one or more amines of the formula:
• R and R have the meanings assigned to them above, in the molecular ratio 1:1, in organic solvents at low temperature.
• the impregnation of the fibrous material is effected with a liquid-containing preparation which contains the triazine compound.
• a liquid-containing preparation which contains the triazine compound.
• solutions of the compounds in inert organic solvents i.e. those not reacting with halogen atoms of the triazine compounds
• inert organic solvents such as carbon tetrachloride, dichloroethane, methyl ethyl ketone, benzene, xylene, perchloroethylene and petroleum hydrocarbon
• the impregnating liquid may be an aqueous emulsion of the triazine compound.
• the triazine compounds are not liquid at room temperature, so that to formulate the emulsions it is preferable to dissolve the triazine compound in an inert solvent, for example chlorobenzene or a dichlorobenzene, and to emulsify the resulting solution in water.
• an inert solvent for example chlorobenzene or a dichlorobenzene
• only a small quantity of solvent is generally required in relation to the quantity of the triazine compound, so that the mixture of triazine compound and 501- vent is less a solution in the usual sense than a melt.
• emulsifiers may be employed but in order to avoid saponification of the triazine compounds (exchange of halogen atoms for hydroxyl groups) it is important that the emulsifiers should not be more than at most mildly alkaline.
• Either ionic or non-ionic emulsifiers may be employed.
• the latter class includes, in particular, polyglycol compounds, for example polyglycol ethers of aliphatic alcohols of high molecular weight.
• water-soluble poly vinyl alcohol or a polypeptide-containing substance, such as gelatine may be included as a thickening agent, preferably in addition to a polyglycol compound.
• agents for the finishing of the fibrous materials may be added to the aforesaid preparations, for example dressing agents, such as agents which are capable of exerting a similar action to the triazine compounds.
• Examples are agents capable of imparting a soft handle to the textile material or water-repelling agents such as wax-like substances, e.g. paraffin wax, chloro-paraffin waxes, or a fusable polyalkylene such as polymerized ethylene, propylene or isobutylene.
• the wax-like substances may be simply added to solutions of the triazine compounds in organic solvents or, when the preparations are emulsions, they may be dissolved in the organic liquid of the emulsion together with the triazine compound. They may also be dissolved in an organic solvent separate- 1y from the triazine compounds, whereby emulsions comprising two different discontinuous phases may be produced.
• the triazine compound content of the preparations may vary within wide limits.
• preparations may be directly prepared in which the concentration is, for example, from 3 to 10 parts of triazine compound in parts of the preparation.
• the fibrous materials may be impregnated in any usual manner, for example by dipping, spraying or coating, advantageously at room temperature or at most at a slightly elevated temperature. It is particularly desirable to impregnate woven fabrics with the preparations on :1 padding machine.
• the impregnation is followed, if desired after intermediate drying at room temperature or at most at slightly elevated temperature, by treatment with an acid-binding medium, with the object of inducing chemical reaction between the halogenotriazine compound and the fibrous material, so that the triazine compound becomes attached (in homoeopolar fashion) to the fibrous materinl, for example to the oxygen atoms of a cellulosic fibrous material.
• This treatment may advantageously be carried out with dilute aqueous sodium carbonate solution. Temeratures of at most 30 to 40 C. are generally sufiicient for the treatment, e.g. in the case where dichlorotriazine compounds are employed.
• the treatment of the fibrous materials by the process of the present invention generally produces a water-repelling efiect and at the same time imparts a soft handle to the fibrous material.
