Definitions
- the nature of the goods used, the degree of refinement achieved through any previous work stages and the desired work goal determine the selection of the chemicals or chemical mixtures suitable for the respective work stage and the working conditions for their action and / or reaction on the textile material.
- the teaching according to the invention is based on the sustainable need of practice, substantial savings in working time, the number of absolutely necessary work stages and, if appropriate, also Allowing a number of previously separate work stages to be combined into one work step.
- Both publications describe new ways of spraying aqueous treatment liquors onto web-shaped textile goods, the last-mentioned publication in particular dealing in detail with the technological problems of fleet application by aerosol / superheated steam spray application. Constructive measures for overcoming the multifaceted difficulties of this technology are proposed.
- the teaching of the invention described below builds on this knowledge of modern process management in the continuous process.
- the invention intends to make the applicability of these technical possibilities widely accessible and in an improved form.
- the invention also intends to open up the possibility of combining a plurality of previously separate process steps into one treatment stage. But even without this further conception, it should be possible according to the invention to rationalize the respective treatment stages in the continuous process and, in particular, to drive them in a shorter time.
- the proposed solution according to the invention provides for the combination of a specifically selected method for applying the treatment liquor to or into the textile goods and the targeted influencing of the behavior of the treatment liquor on and in the textile goods during and after their application under the working conditions.
- the teaching of the invention aims to ensure that individual, separate process stages are carried out in the shortest possible manner Periods can be carried out reliably and / or that a plurality of successive process stages can be combined to form a multifunctional and in particular time-shortened work step.
- the invention relates in a first embodiment to a process for spraying aqueous active substance liquors onto textile materials, in particular as part of the continuous treatment of web-shaped textile goods, the method being characterized in that work is carried out with aqueous active substance fleets which are carried out under under the conditions of the spray application, foam-free or at least low-foam deaerator components dissolved, homogeneously emulsified and / or homogeneously dispersed in such an increased concentration that the penetrating wetting of the textile takes place practically immediately.
- the teaching of the invention provides, in particular, to carry out the spray application of the aqueous active substance liquors as a hot application, the spray application as an aerosol / superheated steam system and thus the simultaneous introduction of kinetic and thermal energy into the textile web being preferred.
- concentrations of the deaerator components in the active substance liquor are preferably selected such that the complete wetting of the textile material, including the displacement of even microdisperse residual air components from the textile inner structure, is effected within a period of at most a few minutes under the working conditions.
- the preferred period for this full vent is below
- Inclusion of the displacement of microdisperse residual air amounts is at most about 5 minutes and is preferably not above about 1 minute.
- the desired work result of the complete textile ventilation is practically immediate and, together with the liquor application, is sought and practically achieved.
- the invention relates to the use of such a method for shortening the treatment time of individual, but also possibly for combining several work stages in the continuous treatment of raw textile goods and / or in textile finishing.
- the teaching according to the invention provides for the summary of essential work stages from the pretreatment technology of cellulose-containing textile materials, in particular based on cotton, optionally in a mixture with fibers or fibrous materials of other natural and / or synthetic origin.
- the invention relates in particular to a process for the simultaneous desizing, boiling and bleaching of cellulose-containing textile materials, and to the agents to be used for this.
- the teaching according to the invention is based on the knowledge that, by suitable selection and use of so-called deaerator components in the aqueous treatment liquors, and precisely under the working conditions of the spray application of the treatment liquor and the time-reduced treatment in the continuous process, errors and / or irregularities in the desired work result can be safely avoided.
- deaerating means addresses a comparatively small class of substances for the person skilled in the field of textile manufacture and processing, which in the sense of the teaching according to the invention is additionally characterized by the ability to rapidly increase the surface of fibers in the aqueous phase wetting without having a pronounced tendency to foam.
- aqueous treatment liquors which are applied by spraying and in particular via the working method of the aerosol / superheated steam spray application are applied to the textile goods.
- These liquors generally contain additives for the desired chemical reaction on the fiber surface, which in turn are more or less capable of forming foam in an aqueous liquor and then, due to the application method chosen here, by means of considerable kinetic energy via the aerosol spray state can also lead to substantial foam formation on and in the textile web.
- ventilators are used here which, under the conditions of the spray application and in particular when aerosol hot steam is applied to the textile web, not only do not themselves cause foam formation, but are also capable, if necessary the direct use of other active ingredient components - for example corresponding surfactant components - to directly destroy foams and / or prevent foaming. It is only when these additional conditions are taken into account that the really broad applicability of the simplified and accelerated textile treatment process in the sense of the publications ES-Al-545681 and EP-A1-0352591 cited at the outset is reliably possible.
- deaerator substance class is particularly preferred, namely the class of the trialkyl tri-alkyl esters as described in the literature, cf. in addition to the previously cited parts of TEXTIL-VEREDELUNG the publication K. Reincke "Foam-free wetting in dyeing machines and equipment” Textilpraxis 1973, 461.
- phosphoric acid trialkyl esters in a mixture with emulsifiers is described here.
- the invention provides for the use of phosphoric acid triesters of lower alkyl alcohols, which can be at least partially alkoxylated as deaerators. It may be preferred that at least 50 mol% and in particular at least 75 mol% of the lower alkyl alcohols used for the ester formation have been used in the form of their alkoxylated representatives for the production of phosphoric triester. Corresponding phosphoric triesters in which alkoxylated lower alkyl alcohols have been used almost exclusively as ester-forming reactive components are particularly suitable.
- the phosphoric triesters particularly suitable according to the invention are derived from alkoxylated straight-chain, branched and / or cyclic C ⁇ _6 alkyl alcohols, which preferably have an average degree of alkoxylation between about 1 and 5. Lower degrees of alkoxylation within this range, ie values of about 1 to 2, may be particularly suitable.
- Suitable alkoxy radicals are, in particular, the corresponding radicals of ethylene oxide and / or propylene oxide, trialkoxyethylphosphates being a particularly preferred class of substances for the purposes of the action according to the invention. An important representative from this class is tributoxyethyl phosphate.
- deaerators of the type defined last have the multifarious combination of desired and absolutely necessary effects which make advantageous work possible in the sense of the invention: phosphoric acid triesters of alkoxylated lower alkyl alcohols can also be stably emulsified in aqueous liquors which contain a large amount of electrolytes , generally sufficiently self-emulsifiable. Despite this rather surfactant-like change in the molecular structure, they have the required combination of material properties, above all freedom from foam and the ability to remove static residual air thoroughly and practically immediately from the textile goods treated with appropriate aqueous liquors.
- deaerator amounts - in particular deaerators of the type described phosphoric acid esters - can be used in the aqueous treatment liquors in amounts of up to about 1 to 2% by weight, preferably up to about 1% by weight, but at least in the process should be present in amounts of about 0.01 to 0.02% by weight.
- the range from about 0.02 to 0.5% by weight of the deaerators, based on the aqueous liquor, can be of particular importance.
- the general rule is that, in individual cases, inadequate results with regard to ventilation and / or foam inhibition can initially be improved by increasing the content of phosphoric acid triesters in accordance with the concept of the invention.
- the web material in particular in the form of a web can be used as dry goods or as wet goods. It is preferred to limit the water content of wet feed to values of at most about 100% by weight and in particular to values of not more than about 80% by weight -% by weight in each case based on the dry weight of the textile. In a further preferred embodiment of the teaching according to the invention, it may be expedient to heat the wet or also the dry textile material before the spray application of the liquors modified according to the invention. This heating can take place in any known form.
- the use of goods heated in this way for the spray application then makes it possible, particularly in the case of liquor application by the aerosol / superheated steam process, to reliably check the predetermined concentration ratios of the active substances in the liquor entered. Dilution effects due to condensing superheated steam on the initially cooler textile material are thus reliably excluded.
- the amount of the total liquid phase entered is determined according to the respective process requirements. In general, the upper limit is such that the liquor carrying capacity of the textile material is not exceeded or is not significantly exceeded.
- the numerical determination of this fleet carrying capacity is determined by the particular nature of the textile material and is, for example, in the range from about 100 to 300% by weight, based on the dry weight of the textile. In important cases - for example in the pretreatment of textile webs containing cotton or cotton, the liquor carrying capacity is often in the range of around 150% by weight.
- the spraying of the liquors is carried out on one side or preferably on both sides of the web-like goods, and repeated spraying can also be provided on one or on both sides of the textile goods.
- the use of sufficient kinetic energy in the spray application can be important. This not only promotes the penetration of the textile web with the liquid phase, but under the influence of the deaerator added according to the invention, the pushing force of the liquid phase in the textile web can have the important function of displacing the microdisperse residual air.
- an optimized combination of thermal and kinetic energy is introduced into the textile web to be treated by the fact that the spray application mentioned above is carried out by means of an aerosol / superheated steam process.
- the application of liquor under increased spray pressures by means of multi-flow mixing nozzles with an external mixture of sprayed aqueous liquor and pretensioned superheated steam which is shown, for example, in EP-A1-0352591 using suitable spray nozzle types, has proven successful.
- both the spray jet of the aqueous liquor and the water vapor jet are expelled from separate openings of the spray device under elevated pressures - for example 2 to 4 bar overpressure - and before the Impinging mixed on the textile web to be treated.
- the hot liquor finally striking the textile material in this mixed state is immediately activated due to the thermal energy supplied and can thus optimally fulfill the task assigned to it on the fiber surface, with the use of the deaerator component (s) in the sense of the invention ensures the uniform effect of the textile fleet across the entire range of textile goods, including in its microstructure.
- aqueous treatment liquors used The nature of the aqueous treatment liquors used is determined by the intended processing purpose. In the simplest embodiment, reliable venting of the textile goods into wet-saturated goods can be aimed for, which in this state is then transferred to a subsequent work step. In practice, an aqueous solution, emulsion and / or dispersion of the deaerator component can be used without the addition of other active ingredients.
- the invention provides for the joint use of the deaerator components described with further additives for the intended textile treatment in the liquor, which in turn can be present in the aqueous liquor as a solution, emulsified and / or dispersed.
- treatment liquors are used which, together with the deaerators, contain active substance mixtures for the simultaneous operation of a plurality of textile finishing stages. Details of this are given below.
- the web-like textile material is applied in a continuous process to the liquor containing deaerators and active ingredients or active ingredient mixtures, preferably by means of aerosol / superheated steam, and can subsequently at least one further hot and / or cold stage are treated.
- the web-like textile material is applied in a continuous process to the liquor containing deaerators and active ingredients or active ingredient mixtures, preferably by means of aerosol / superheated steam, and can subsequently at least one further hot and / or cold stage are treated.
- the process technology of the so-called pretreatment of textile goods based on cotton or cotton as a fiber component containing oil component generally consists of 3 process steps, desizing, the alkali stage and the peroxide bleaching stage.
- current practice provides for at least 2 process steps, desizing and the peroxide bleaching stage.
- each of the pretreatment stages desizing, alkali treatment and peroxide bleaching consists of the sub-processes application, reaction and washing.
- the reaction times under saturated steam conditions alone are between 3 and 15 minutes at the alkali stage and between 7 and 15 minutes at the peroxide bleaching stage.
- the invention not only wants to substantially shorten the duration of the process stages, it actually wants and achieves the combination of these stages in one treatment step.
- the required goals for such pretreatment must also be able to be set reliably in the new process. It must therefore be guaranteed: a high degree of whiteness depending on the subsequent processes, sufficient shell freedom, high rewettability, sufficient Degree of desizing and optimal removal of the accompanying substances of the native cellulose.
- the process according to the invention makes it possible to combine these 3 stages of desizing, boiling and bleaching in one process stage by working with selected aqueous liquors which contain the active ingredients required in a mixture with one another.
- the implementation of this concept is, however, bound to the core of the teaching according to the invention at the same time in the fleet to also now use the breather, which in the specified manner leads to the practically immediate expulsion of static air fractions, including the microdisperse residual air, and on the other hand also the foam formation when the fleet is applied prevent under increased spray pressure.
- the washing stage which is generally provided as a final step is still a comparatively complex working step and it is desirable to be able to restrict both its duration and the amount of washing water required.
- EP-A1-0258816 the applicant describes an improved method for washing and cleaning textiles, which is characterized by the action of ultrasound on the textile material in the wash liquor to accelerate the cleaning action.
- Decisive for the applicability of ultrasound washing, particularly in the case of textiles, is the prerequisite that the fiber microstructure of the textile is thoroughly wetted and vented while displacing microdispersed residual air. Regarding the regularities affected here. the details of the cited EP-AI.
- the textile webs treated in the sense of the teaching according to the invention have now actually reached this state of complete freedom from static residual air and in particular also from the microdisperse residual air by definition.
- the wet material from the treatment stage according to the invention is accordingly particularly suitable for use in a downstream washing stage which is accelerated by the action of ultrasound. This enables further substantial savings in time and effort.
- the pure desizing of a textile raw material without subsequent or simultaneous bleaching using thermostable enzymes and / or by oxidative means The combination of an oxidative desizing plus boiling with the use of bases; The combination of desizing, boiling and bleaching; Leaching under comparatively higher alkali concentrations; The combination of oxidative desizing and leaching; A combination of desizing, boiling off and leaching and, if necessary, simultaneous bleaching; The peeling of polyester fibers to reduce the fiber titer; Mercerization (exposure to alkali under tension); Classic steps in the field of dyeing; All work steps from the field of "pad steam treatment", for example padding (dipping / squeezing) and steam "padding".
- the invention relates to agents and a method for simultaneous desizing, boiling off and bleaching of cellulose-containing textile materials.
- Cotton contains natural impurities, for example pectins, waxes, fats, proteins, seed husks and mineral constituents, as well as impurities which are applied as foreign substances during the production of the textile material, for example preparations, rinsing oils and sizing agents. These contaminants must be completely removed from the textile material in order to avoid later malfunctions during the finishing. This is done by pretreatment, ie by desizing, boiling and then bleaching the cellulose-containing textile materials.
- the pretreatment of cellulose-containing textile materials is carried out continuously in several successive process steps by passing the textile material through the respective treatment liquor, then after squeezing off excess liquor, the treatment agent in a saturated steam atmosphere at 100 ° C. for 7 to 15 minutes allows the textile material to act and then the dispersed impurities and the treatment agent are removed from the textile material by washing.
- the subsequent, next process stage is carried out in the same way.
- This multi-stage process which consists of up to 4 process stages, namely desecondation, boiling, bleaching and leaching, is very time-consuming.
- only very specific impurities can be removed from textile materials with each of the known treatment agents, so that a treatment agent with a different chemical composition is required for each process step.
- the object on which the invention is based was therefore on the one hand to provide means with which cellulose-containing textile materials can be desized, boiled and bleached at the same time, and on the other hand to develop a process with which it is possible to add cellulose-containing textile materials at the same time within a short time desize, boil and bleach. It has now been found that - provided the teaching according to the invention is observed - cellulose-containing textile materials can be simultaneously desized, boiled and bleached using agents which contain mixtures of selected anionic and nonionic surfactants in certain amounts.
- the present invention accordingly relates to an agent in the form of an aqueous solution or dispersion, containing, based on the water-containing agent, 5 to 20% by weight of anionic surfactants, in particular alkali metal, alkaline earth metal and / or ammonium salts of Ci2_i8 alkane sulfonates and / or Cö-jg alkyl sulfates 2 to 10 wt .-% nonionic surfactants, especially alkoxylated aliphatic

- C 5 alkyl alcohols can be linear, branched or cyclic.
- the degree of alkoxylation is between 1 and 5.
- Tributoxyethyl phosphate for example, is suitable as the phosphoric acid triester.
- the agents according to the invention preferably contain nitrogen-containing and / or nitrogen-free mono, di- and / or polyphosphonic acids and / or their alkali and / or ammonium salts and / or OH-group-containing mono-, di- and / or polycarboxylic acids and / or their alkali and / or ammonium salts, for example 1-hydroxyethane diphosphonic acid (HEDP), aminotri (methylene phosphonic acid) (ATMP), ethylenedia intetra (methylene phosphonic acid), diethylenetriamine penta (ethylene phosphonic acid) and their alkali and / or ammonium salts, gluconic acid, Sodium gluconate, tartaric acid and / or citric acid or else acrylic acid homo- and / or copolymers, nitrilotriacetic acid (NTA) and / or polyphosphates.

If the multicomponent mixture to be applied as an aqueous liquor shows sufficient stability even when the components used are mixed in only one treatment liquor with the active substance concentrations to be selected in the respective process, the mixture of these active substance components can be mixed to form a flute batch and in this form into the Liquid phase leading nozzles of the superheated steam spray application system can be fed.
- the treatment liquor is made available, for example, with the aid of a single component metering in the process according to the invention.
- the partial liquor streams may be expedient for the partial liquor streams to be combined with one another immediately before they occur to mix with one another in the spray nozzle, so that the state of the mixture only exists for a very short period of time before the liquor hits the textile material.
- the two extreme cases of dosing multicomponent active ingredient mixtures described here can also be combined with one another, so that, for example, partial liquor streams are provided which at least partially contain partial mixtures of the total valuable or active ingredients to be applied. Considerations regarding the appropriate choice of application technology are also determined, among other things, by the degree of preservation of individual or more valuable substances in an aqueous liquor, in particular when mixed with the other active ingredient components.
- Another factor that has to be taken into account in this connection can be the choice of the particular nature of the textile material to be treated. If the textile material is fed into the process step of the invention as a dry material web, comparatively lower active substance concentrations can be used in the treatment liquor than in the case of the corresponding wet-on-wet application. In the latter case, for example, the degree of maintenance of increased concentrations of active ingredient components at risk of decomposition - for example hydrogen peroxide - can be jeopardized to the extent that the use of single component dosing offers itself as a way out.
- the degree of whiteness was measured on a Spectrophotometer RFC 18 from Zeiss and reported according to Berger.
