Definitions

• the present invention relates to a process for the onebath dyeing and printing of textile material.
• This invention now relates to the one-bath dyeing and printing of textile material made from synthetic or natural fibers or blends of such fibers with suitable dyestuffs according to a continuous or semi-continuous padding or printing method, which comprises applying to the material a padding liquor or a printing paste containing an organic solvent, one or more organic dyestuffs, if required a chemical agent for the fixation of these dyestuffs, Water and a phosphine oxide of the general formula 1) and/or an amine oxide of the general formula (2) 0 R1 0 R1 R-i Riq in' which R, R and R each stands for an unbranched or branched alkyl or alkenyl group of 1 to 18 carbon atoms, which may be substituted by hydroxy, cyano or amino groups or by halogen atoms and which may be interrupted by oxygen, sulfur and/or nitrogen atoms and/or by a carbonyloxy, carbamoyl or sulfamoyl group, and the radicals R and R
• the instant process differs from methods known in this field in that the dyeing media consisting of mixtures of water with organic solvents also contain phosphine oxides and/or amine oxides of .the above-mentioned chemical constitution specified by the formulae given above, which have polyfunctional properties that exert a favorable influence on the dyeing and printing operations of the invention as well as on the dyed products resulting therefrom:
• the above-cited phosphine oxides and/or amine oxides may be used to prepare dyeing liquors which, depending on the solvent used and on the amounts of product and water employed, provide clear solutions or emulsions or emulsified dispersions of low, medium or high viscosity. Seen from a practical point of view, this effect of the substances both as emulsifiers and as thickeners means that the problems that occur in dyeing because of material and machinery, can be overcome also by an addition of these products.
• the solubilizing effect of the products also allows the process of the invention to use such dyestuffs in a dissolved form which are usually considered insoluble as well in the organic solvent used as in water.
• the dye stuff preparation is applied to the textile material, preferably by pad-dyeing, but also by spraying, doctoring and other techniques that assure a continuous operation, for example printing.
• the pad-dyeing operation is generally performed at room temperature but it may also be carried out at any lower or higher temperature ranging from the freezing point to the boiling point of the solvent mixture used or of the azeotropic mixture that may result therefrom. If, however, high-viscosity dyeing liquors are to be used, for example to prevent migration, the temperature applied should be about room temperature, or a laboratory test should previously be made to determine the maximum temperature at which the thickened emulsion is still stable.
• the dyeings or prints are subjected to a suitable fixation method which depends on the dyestuffs used.
• the material which has been padded or printed with the dyestuif preparation may be subjected immediately afterwards in moist state to a steaming or pressure-steaming process, optionally using superheated steam or solvent vapor (one-bath pad Wet-steaming process). It is also possible to steam under the conditions mentioned above the pad-dyeings or prints'after an intermediate drying operation at relatively low temperatures of up to a maximum of C. (one-bath pad steam process) or to thermosol them on a tenter frame or a perforated drum drier by sucking dry hot air through them or by means of contact heat (thermofixation process).
• the favorable conditions of one-bath dyeing are preserved by batching up the textile articles, which have been padded or printed with the dyestuif preparation, and allowing the fibrous material to dwell in moist state on a skein at room temperature or at a moderately elevated temperature of from 30 to 60 C. for 2 to 24 hours, preferably for 4 to 14 hours (one-bath pad-batch or pad short-dwell process).
• This semi-continuous technique is characterized by a high economy of operation, due to the saving of energy, and does not require expensive intermediate-drying and fixing apparatuses.
• fixation may be followed by an after-cleaning operation, for which the phosphine oxides and/or amine oxides mentioned may also be used in the aqueous or solvent-containing after-treatment liquor.
• the process of the present invention is suitable for the continuous or semi-continuous dyeing and printing of various fiber types of synthetic or natural origin, for example of woven or knit fabrics, combed material, cables and nonwovens (fleeces) made of polyester, polyamide, polyurethane, polyacrylonitrile, cellulose-2 /2-acetate, cellulose-triacetate, polyvinyl chloride, polyvinyl alcohol, polypropylene or cellulose fibers or wool or of blended materials of these fibers.
• organic solvents suitable for the process of the invention there are especially used hydrocarbons and, in particular, halogenated, especially chlorinated, hydrocarbons, particularly perchloroethylene (tetrachloroethylene), trichloroethylene, trichloroethane, tetrachloroethane, methylene chloride, chloroform, carbon tetrachloride, fluorotrichloromethane or trifiuorotrichloroethane.
• benzene, chlorobenzene, cyclohexane or gasolines as well as mixtures thereof which may boil while forming azeotropic mixtures.
• the mixing ratio of organic solvent to water in the dyeing liquors and printing pastes ranges from 1-99, preferably 30-98% by volume of organic solvent to 99-1, preferably 702% by volume of water.
• the phosphine oxides and amine oxides are used, according to the invention, either as such or in mixture with each other in amounts of from 1 to 100 g./l., preferably from 3 to 60 g./l., calculated on the mixture of organic solvent and water.
• the phosphine oxides or amine oxides mentioned under formulae (1) and (2) or mixtures of these products are first dissolved in an organic solvent, preferably at room temperature.
• an organic solvent preferably at room temperature.
• water-insoluble dyestufls for example of the disperse dyestuff type, may also be dissolved in this solution.
• This dyestuff type comprises not only dyestuifs which have a good solubility in theorganic solvent used without an addition of the adjuvants of the invention but also a large number of dyestuffs which are usually not, or only sparingly, soluble in the organic solvent used but can be solubilized or substantially improved in their solubility using the cited products offormulae (1) and (2).
• water-soluble dyestufls are dissolved in the water portion of the padding liquor or water-insoluble dye-stuffs are also dispersed therein at a temperature of from room temperature to 0., preferably from 40 to 60 C.
• This aqueous solution or dispersion is then slowly added while stirring to the solution of the phosphine oxides and/or amine oxides and, where required, of dyestuffs, in an organic solvent.
• the results are from clear solutions up to low-viscosity and high-viscosity emulsions or emulsified dispersions.
• the process of the invention is practically suitable for any dyestuff class which can also be applied from an aqueous liquor, for example disperse dyestuffs, vat dye stuffs, reactive dyestuffs, acid dyestuffs, metal complex dyestuffs, chroming dyestuffs, substantive dyestuffs, leuco esters of vat dyestuffs, cationic dyestuffs, developing dye stuffs and the like.
