Textile treatment process carried out in a number of separate work stages, with the whole treatment of converting the untreated material into a material that can • be further processed, time consuming and costly «. Patent application P 19 32 235β 1 describes and claims a method by which a textile material can be desized and dewaxed by applying an emulsion of a desizing _{agent in a hydrocarbon or halogenated hydrocarbon solvent to it o} In patent application P 20 22 929 ° 2 a process is described and claimed in which an emulsion of a bleaching agent in a hydrocarbon or halogenated hydrocarbon solvent is applied to the fabric, which makes it possible to desize, dewax and bleach a textile material in a process that takes only 2 minutes A further improvement of this process is described in the patent application filed at the same time (folder 22691), in which the bleaching treatment is carried out in the presence of a base with an emulsion of aqueous hydrogen peroxide, and this process improves bleaching is achieved.

According to the present invention it has now been found that this methods described above can be modified in this way can that a dye is incorporated into the emulsion to be applied to the textile material, so that in this way both coloring and desizing in a single bath of the material can take place.

The present invention therefore proposes a method for handling development of textile materials, which consists in applying an emulsion of an aqueous desizing agent in a hydrocarbon or halogenated carbon to the textile material.

2098U / 1727

Hydrogen solvent is applied, this emulsion also contain a dye

If a "dye" is mentioned here, it should include it Pigments, especially finely ground pigments, are understood *

According to a further feature of the invention, there is an emulsion of an aqueous desizing agent in a hydrocarbon or halogenated hydrocarbon solvents, which also contain a dye

The dye can be in either the aqueous or non-aqueous phase of the emulsion, or both, so the dye used can be water-soluble, solvent-soluble, or can be used in the form of an emulsion. The dye should be selected and used in such proportions that it does not destroy the emulsion or reacts adversely to an unacceptable high degree with other components of the emulsion and it should also be selected with regard to the type of textile to be treated _o Examples of suitable dyes are reactive dyes, for example reactive cellulose dyes, solubilized leucocup ester dyes _s disperse dyes and direct dyes. The concentration of the dye in the emulsion will depend upon the particular dye used and the desired color tone and is generally between 0.01 and 5 $ "in particular between 0.05 and 2 ° f _t based on the weight of the emulsion, are, although any concentration can be used, taking care that this does not break down the emulsion used _e

In certain cases additional reaction substances are required,

to develop the shade »For example, solubilized Leuco vat ester dyes in the usual way by application from aqueous acidic nitrite. These additional reactants can be incorporated into the emulsion and / or they can be applied to the textile material after it has been impregnated with the emulsion, and preferably after the hydrocarbon or halogenated Hydrocarbon solvent has been removed "if, for example a Leukoküpeneeter dye is used, the aqueous phase of the emulsion can contain a nitrite *, for example Sodium nitrite, can be added and the textile material is after removal of the hydrocarbon or halogenated hydrocarbons The liquid is passed through a bath of a dilute acid the dye is developed "

The aqueous desizing agent used is preferred an oxidizing agent that also has the function of it at least partially bleaches the textile material, although non-oxidizing sizing agents are also used Agents are, for example, enzyme sizing agents. the Use of emulsions of enzyme solubilizers in Hydrocarbon and halogenated hydrocarbon solvents are used in the treatment of textile materials Patent application P 19 32 235.1 describes »If the material is not easily colored and the dye used has a comparatively dark tint Bleaching in general may be necessary to get a satisfactory one Achieve coloring EU. i

The Bleiohbehandlung can be carried out in the catfish "that

2098U- / 1727

A special bleach is used in addition to the desizing agent. In practice, however, it is more twofold
to carry out any necessary bleaching in such a way that an oxidative desiccant is used which has a bleaching effect at the same time, for example sodium chloride, sodium hypochlorite, hydrogen peroxide or peracetic acid. Aqueous hydrogen peroxide is preferably used.

The Effectiveness of Hydrogen Peroxide as Sntschlichtung /
Bleach is enhanced by the presence of a base
Thus, when hydrogen peroxide is used, it is preferred to carry out the desizing / bleaching treatment in the presence of a base. The base can be incorporated into the emulsion or it can be applied to the textile material after it has already been impregnated with the emulsion
Examples of suitable bases are ammonia, alkali metal hydroxides, for example sodium hydroxide, alkali metal alkoxides, for example sodium methoxide and sodium ethoxide, metal carbonates, for example sodium carbonate, and primary, secondary and tertiary amines, for example diethylamine and Oycloihexylamino - 'lie' using peroxide in the presence of a base
detailed in the patent application filed at the same time
(Cap 22691), in which examples are also explained for the implementation of the method «

The amount of duck loaf / lead used can be varied within wide limits and is usually reduced to 0.5%, based on the amount of oil used in the emulsion,
and it can be the same as it is used in fan customary aqueous processes. Most practical duck lightening / bleaching treatments are not

part in the use of a concentration of desoling / Bleaching agents greater than 5 ~ wt. # Of the emulsion, although if desired higher concentrations can also be used - ■ · can »In general, it can be stated that the greater the The greater the concentration of desoling / bleaching agent will also be the amount of emulsifier required to form the! emulsion. »It has been found that at Increasing the concentration of the emulsifying agent causes a thickening the emulsion takes place and for mechanical reasons it is preferred to use a thin emulsion »

The amount of desizing / bleaching agent applied is selected such that the desired concentration is present in the emulsion. For example, if the desizing / bleaching agent consists of aqueous hydrogen peroxide, this is preferably used in an amount of 1.5 to 10 Qew _o - # of the emulsion, so that the concentration of hydrogen peroxide in the emulsion is from 0.5 to about 3 »5 wt. -4> is»

The emulsion will usually contain an emulsifying agent - and it is advantageous that this is also a surface-active Is a means which «facilitates the wax treatment of the textile after removal of the solvent» In the case where the emulsifying agent is not itself a surfactant When the agent (or wetting agent) is, a surfactant is usually added to the emulsifying agent added. Anionic, cationic or nonionic surfactants can be used as emulsifying agents as well as mixtures thereof and examples of suitable compounds are condensates of alkylphenols?) (for example Nony! Phenol) with ethylene oxide, Salae of alkylarylsulfonic acids » for example amine salts of dodeoylbenzenesulfonic acid, '

Coconut oil diethanolamide, Salse of the monosulfonic acid derivative of diesters of a succinic acid, for example sodium di (methylamyl) sulfoBUCcinate, and salts of sulfated fatty -alcohols * There are also suitable means by which the viscosity the solvent is increased «. When choosing a "special Emulsifier is the type of in the emulsion to be used reactants and there should be a Emulsifying agents are selected, 'which by the Reaktipnsstoffe is not significantly affected.

You concentration of the emulsifying agent (which, as mentioned, a wetting agent for the textile material is also advantageous) does not need to be significantly larger than it is required at the moment is to induce the emulsification of the aqueous phase * - The concentration of the emulsifier becomes common from 0.25 to 5% by weight of the emulsion, and preferably from 1 to 2 percent by weight of the same, if both an emulsifier and a separate surfactant is present, the amount of each agent should be from 0.25 to 5 Gewo- # of the emulsion amount

Hydrocarbon solvent wets and as a result leaves the application of emulsions according to the invention is rapid and simply carry out «, the emulsion can for example by Immersion of the textile material can be applied in this or by spraying, padding or applying by means of a roller « The temperature of the emulsion when it is applied to the textile material is preferably at room temperature, so that solvent losses can be kept low while using them, although higher temperatures can also be used, provided that the emulsion does not break down and decomposition of the reactants it contains is avoided »

Impregnation of the fabric with the emulsion is common carried out under such conditions that any solvent-soluble substances in the fibers in contact with remain with the impregnated material »If the textile material is impregnated by immersion in the emulsion bath, so is it is advantageous to use short immersion times in order to avoid contamination of the emulsion in the bath.

If it is desired to use the process in conjunction with a conventional solvent purification process, it may the emulsion is also applied to the solvent-moist textile material if this is the solvent cleaning vessel leaves.

After application of the emulsion, the hydrocarbon or halogenated "hydrocarbon solvent is essentially removed from the textile material. The reaction of the reactants in the emulsion on the textile material can take place before, during or after the removal of the hydrocarbon or halogenated hydrocarbon solvent"

2098U / 1727

Any additional reactants that are required can be used in conjunction with those present in the emulsion Reactants act on the textile material before, while or applied after the solvent has been removed. Finally, the textile material can finally be washed »

There can be any method of removing the solvent may be used, for example air drying, particularly using hot air. It is preferred to remove the solvent quickly, for example by using a rapid evaporation (flash-off) of the solvent »The sioh -Resulting solvent vapors can be condensed in order to be able to reuse the solvent. Is is preferred to bring the impregnated textile material into a steam atmosphere, all the more quickly to drive off the solvent in a known manner In this case, the steam preferably flows essentially in the opposite direction to the direction of movement of the textile material «

The length of time the textile material is kept in contact with the steam or warm air should be sufficient to remove substantially all of the material, and furthermore, if desired, to remove any chemical reaction of the reactants resulting from the emulsion the textile material has been applied to promote · In general Treatment tents of 20 to 120 seconds are sufficient for this purpose, although shorter ones are desirable or longer treatment tents, for example 10 seconds up to several minutes, in certain. Cases can be applied o Jfaoh removal of the solvent, desizing, Bleaching (if desired) and dyeing (including one any development or fixation of the dye) the textile material is preferably washed, for example

with an alkaline aqueous solution, but it is not necessary that the textile material is washed immediately after the specified treatment process and if necessary can be a further treatment, for example, between the working steps of solvent removal and washing treatment a high temperature steam treatment, can be switched on.

The first Wasohbehandlung is usually, but not necessarily, carried out in a dilute alkaline solution, for example in a dilute solution of sodium carbonate "Subsequent washing treatments, one of which Anzah l, can be made to be hot performed or cold, with diluted alkali solution , Soapy water or plain water ο

The process forming the subject of the invention can be carried out continuously be carried out, in a manner similar to that described in patent application P 20 22 929.2 »

The machine in which the procedure is carried out contains preferably means and equipment for the recovery of the solvent, in particular from the tree in which the removal is carried out of the solvent is carried out. The entire machine or apparatus should preferably be enclosed to avoid an escape to avoid the solvent fumes in the atmosphere. The recovery of solvent vapors from the solvent removal zone (and other zones if desired) can be done by conventional means, for example by condensation and if desired by adsorption. A water trap is also usually provided to remove the condensed solvent to separate from the aqueous water, the recovered solvent can be fed to a storage container after ea

has been cooled if necessary "and it can then be used Recovery to be reworded ..

Like the method of patent application P 20 22 929 ° 2, the method forming the subject of the present invention can also be used for the treatment of materials in various forms, for example woven or knitted textiles, mushrooms and other sheet materials or loose fibers * which are carried on a suitable transport system , for example an endless belt _r »Textiles made of natural or synthetic fibers can be treated, as well as mixtures of natural fibers and synthetic fibers» The method is particularly suitable for the treatment of textiles made of cotton fibers or mixtures of polyester fibers with cotton fibers or regenerated cellulose fibers ^ though Textiles made of other yarns or mixtures of yarns can also be treated in this way * Woven or knitted textiles are preferably treated in the open width those that have been singed and / or subjected to a heat-setting treatment before the bleaching treatment. To b ehandelnden textile materials do _o not be dry by the process of the invention, steam wet fabrics can be treated, for example containing 40 i "water.

If the textile material consists of a mixture of fibers, thus the dye can initially act preferentially on fibers of a certain chemical composition. In this case The usual means can be used to make the coloration more even by transferring the color toffee to

the other pasers. For example, if a polyester-cotton ' textile fabric is dyed according to the invention, with a

209814/1727

soluble leuco vat ester dye (O ₀ Io solubilized. vat green 1 dye), the dye initially precipitates on the cotton fibers. However, if the textile fabric is heated in dry air, the dye migrates into the polyester component and a uniformly colored textile fabric is obtained.

The invention is explained in more detail in the following examples, in which the parts and percentages relate to weight, unless otherwise noted. The abbreviation "CoI ₃ " used in the examples refers to the Color Index jointly published by The Society of Dyers and Colourists and The American Society of Textile Chemists and Colorists _P
