Definitions

• This invention relates to improved emulsions in halogenated hydrocarbon solvents of dyestuffs and textile finishing agents, and to the use of such emulsions in the dyeing and finishing of textile fabrics.
• a stabilised emulsion in a halogenated hydrocarbon solvent of an aqueous solution or an aqueous dispersion of a dyestuff or a textile finishing agent characterised in that the emulsion contains as emulsifying agents ethyl hydroxyethyl cellulose and at least one anionic surface active agent.
• ethyl hydroxyethyl cellulose is meant a mixed cellulose ether which is prepared by a process involving the following three reactions l. alkali cellulose formation in which cellulose is swollen by aqueous sodium hydroxide; Cell OH 1+ NaOl-l Cell OI-l.NaOl-l;
• Ethyl hydroxyethyl cellulose is available commercially in a number of different grades depending on its molecular weight. These grades may be characterised by their solution viscosities, ranging from to 250 cp.
• ethyl hy- I droxyethyl cellulose is suitable for use in the emulsions of the present invention, but the grade having a solution viscosity as hereinbefore-defined of 20 35 cp is preferred.
• Anionic surface active agents which are suitable for use in the emulsions of the invention include salts of sulphonated castor oil, known collectively commermore such agents may be employed.
• Halogenated hydrocarbon solvents which may be employed in the emulsions of the invention include trichloroethylene, perchloroethylene, l l l :Trichloroethane, carbon tetrachloride, chloroform, monochlorobenzene and l :2 4-trichlor0benzene.
• Dyestuffs which may be incorporated in the emulsions of the invention include any of the well-known classes, for example acid, basic, direct, reactive or disperse dyestuffs as conventionally employed for the dyeing of textile materials composed of polyamide, cotton, wool, silk, acetate, polyester, viscose or acrylic fibres or filaments.
• Textile finishing agents which may be incorporated in the emulsions of the invention include fluorescent optical brightening agents, such as the sodium salts of bis-triazinyl-aminostilbene di-sulphonic acids, waterproofing agents such as stearamidomethylpyridinium chloride and N-methylolstearamide, crease-resist resins such as dimethyloldihydroxy-ethylene urea, antistatic and antisoil/soil release agents such as condensates of ethylene oxide with polyamides, crystallisable polyesters containing polyoxyalkylene groups, for example polyoxyalkylene terephthalate/polyalkylene terephthalate block copolymers and copolymers of polymerisable acids, for example acrylic acid, with other polymerisable vinyl monomers, softening agents such as fatty quaternary ammonium salts, desizing agents such as enzyme preparations, flameproofing or flame retarding agents such as antimony trioxide or mixtures of boric acid and borax.
• the emulsions of the present invention may be produced by subjecting a'mixture' of a halogenated hydrocarbon solvent and an aqueous solution or dispersion of a dyestuff of textile finishing agent to suitable mechanical agitation in the presence of ethyl hydroxyethyl cellulose and at least one anionicsurface-active agent.
• The'emulsifying agents used that is to say the ethyl hydroxyethyl cellulose and the anionic'agent or agents, maybe initially present in either the halogenated hydrocarbon solvent or the aqueous solution or dispersion of the dyestuff or finishing agent, or both.
• the solubility properties of ethyl hydroxyethylcellulose inparticular the 20 35 cp. I grade which is preferred for use in-the present invention, it will usually be convenient for this constituent to be dissolved initially in-the halogenated hydrocarbon solvent.
• the anionic agent or agents may be dissolved initially in either the solvent phase or the aqueous phase, but if desired, in accordance with a well-known technique of emulsification using such agents, it may be produced in situ by reaction between a suitable organic acid precursor, for example dodecylbenzene-sulphonic acid, dissolved in the halogenated hydrocarbon solvent phase and an alkali, for example sodium hydroxide, dissolved in the aqueous phase.
• a suitable organic acid precursor for example dodecylbenzene-sulphonic acid
• an alkali for example sodium hydroxide
• the relative proportions of the halogenated hydrocarbon solvent and the aqueous phase incorporated in i the emulsions of the invention may vary widely, according to the manner in which the emulsions are to be applied to the textile fabric and to the type and solubility of the dyestuffs or finishing agents employed. Commonly, however, the amount of water will lie in the range 0.3 to 20.0% of the total weight of the emulsion.
• the emulsions of the present invention are valuable for the application to textile materials of the dyestuffs or finishing agents which they contain.
• the emulsions may be applied to the textile materials by passing, exhaustion or any other conventional form of impregnation, followed by evaporation of the halogenated hydrocarbon solvent and, if necessary, a final baking operation to fix the dyestuff or finishing agent on the textile material.
• the halogenated hydrocarbon solvent which is evaporated during this process may, of course, be recovered for re-use.
• Textile materials to which the emulsions of the invention may be applied include yarns and knitted, woven or non-woven fabrics.
• emulsions of the invention instead of conventional aqueous solutions or dispersions of dyestuffs or textile finishing agents confers a number of advantages. Exhaustion may be more rapid in batchwise processes and wetting out easier and pick-up better in padding procedures. Losses in dimensional stability are reduced.
• the halogenated hydrocarbon solvents have lower specific heats and latent heats of evaporation than water, thus reducing costs of heating and drying and also permitting economic recovery of the organic liquid for reuse which avoids the increasingly severe difficulties being met in the treatment of aqueous effluents.
• a number of finishing treatments, and also dry cleaning of textile materials are carried out in nonaqueous media and in suitable cases these may be combined with application of a treating agent to the textile material.
• emulsions of the invention show no detectable separation of the organic and aqueous phases over a period of. several days.
• emulsions of similar composition but containing only the ethyl hydroxyethyl cellulose' as stabiliser, that is to say omitting the anionic surface active agent or agents show appreciable separation after as little as one day.
