Definitions
- the invention relates to an improvement and simplification of machine washing of soiled textile goods in the household and / or business by means of a method in which the aqueous washing liquor is formed in the presence of the soiled textile material by immediately adding a detergent ingredient and in particular surfactants to the dry or only moistened concentrate Textile is added and then the wash liquor is formed in situ by preferably gradually adding water and circulating the textile material.
- aqueous washing liquor is formed in the presence of the soiled textile material by immediately adding a detergent ingredient and in particular surfactants to the dry or only moistened concentrate Textile is added and then the wash liquor is formed in situ by preferably gradually adding water and circulating the textile material.
- washing machines or washing machine types that are common in practice now provide the formation of the wash liquor as follows: the detergent is metered into a washing-up chamber and is washed into the machine body by means of the water flowing into the machine. The desired final concentration of the detergent solution is formed in a comparatively short initial phase, in which the washing process is then carried out.
- the detergents on the market today are usually solid, free-flowing powders or granular substances or pourable liquids.
- the use of surfactant-containing liquid detergents in household washing machines common in Europe can be difficult because the induction chambers can be used for portioned intake of powders, but are not suitable for holding liquid concentrates there until the desired process cycle is intended to be flushed into the machine body.
- the state of the art provides two basic solutions for overcoming these difficulties.
- the first principle is described, for example, in European Patent 0 040 931.
- the portionwise addition of a liquid detergent concentrate is described here in such a way that this concentrate is packaged in sealed bags which are added to the textile goods to be washed before the washing process begins.
- the liquid detergent concentrate is packaged in a water-insoluble and water-impermeable bag made of thermoplastic sheet material, which, however, is sealed by a mechanically weak heat seal in such a way that this closure point opens under mechanical influence when used in the washing machine.
- This opening of the predetermined breaking point in the portioned bag should preferably take place within the first 5 minutes and in particular within the first 2 minutes after the start of the washing process.
- the invention intends to further improve the type of process for machine washing, in which the detergent concentrates are added directly to the textile, and the formation of the wash liquor takes place in situ by adding water to the soiled textile material containing detergent concentrate.
- the invention seeks to make it possible to dispense with portioning elements such as packaging bags or portioning devices of the type described above that are always open and reusable.
- portioning elements such as packaging bags or portioning devices of the type described above that are always open and reusable.
- the teaching of the invention is based on the idea that the detergent concentrate is at least largely dimensionally stable at room temperature in the textile to be washed or in a Enter the textile piece serving as dosing aid and now form the washing liquor in situ by adding water.
- the invention accordingly relates to an improved process for the mechanical cleaning of soiled textile goods with an aqueous wash liquor containing detersive surfactants with portioned addition of surfactant-containing detergent concentrates directly into the textile goods to be cleaned and subsequent formation of the wash liquor by preferably gradually adding water and circulating the textile goods, whereby the new process is characterized in that, if desired, the at least predominant proportion of the detersive surfactants, together with further detergent ingredients, is pasted into the still dry and / or moistened textile goods, at least largely dimensionally stable pasty to dough-like formulations at room temperature.
- At least largely dimensionally stable paste or ointment-like detergent concentrates are used which, under the standard conditions described below, have a dissolution rate in water of at least 40% by weight and preferably of at least 50% by weight: 1 g of the pasty to dough-like detergent concentrate is placed as a coherent material sample in a beaker (250 cm3 tall, approx. 5.5 cm in diameter) and mixed with 100 ml of water at a temperature of 20 ⁇ 2 ° C. A magnetic stir bar (length 3 cm) is placed in the beaker. The contents of the beaker are then at the specified temperature for a period of 15 minutes. stirred at a rotational speed of 500 rpm.
- gel or paste detergent concentrates are used which, under the specified conditions, within a period of 5 min. at least 50%, preferably at least 75% and in particular at least 85% have been transferred to a clear or finely divided solution.
- the detergent concentrates can contain water-insoluble, finely divided active ingredients in a manner known per se, for example builder constituents based on zeolite NaA, or finely divided layered silicates of natural and / or synthetic origin, but also sparingly soluble surfactant components in finely divided form such as finely divided tallow alcohol sulfate low temperatures largely water-insoluble disalts of alpha-sulfo fatty acids and the like.
- detergent concentrates containing water and / or water-soluble solvents are used in spreadable to kneadable formulations, the surfactant content of which is preferably about 75% by weight moderately does not exceed about 60% by weight and in particular about 50% by weight.
- the percentages by weight relate in each case to the weight of the detergent concentrate used.
- dispersing aids to the detergent concentrates, which contribute to the easier disintegration of the paste-like or dough-like detergent concentrates.
- the addition of such dispersing aids may have been advisable, in particular when using surfactants which are sparingly soluble in water at room temperature and / or tend to gel.
- surfactants which are sparingly soluble at room temperature are, for example, tallow fatty alcohol sulfate pastes and other pastes based on long-chain fatty alcohol sulfates, long-chain alkyl glycosides, long-chain ethanol amides, C 16/18 ester sulfonates and optionally also soaps.
- Difficulties can also arise, however, in particular in the dissolution of detergent concentrates of the type dealt with here on the basis of those surfactants or surfactant combinations which tend to gel strongly.
- these are highly concentrated pastes based on fatty alcohol ether sulfate (FAES), for example corresponding 70% FAES pastes.
- FES fatty alcohol ether sulfate
- Other examples of this tendency to gel are long-chain, saturated fatty alcohol ethoxylates, which, in addition to the tendency to gel, have only a moderate dissolution rate.
- examples are components that are derived from C 16/18 or longer-chain components.
- secondary alkanesulfonates such as saturated C 12/14 or C 12/18 fatty alcohol ethoxylates with at least 10 moles of ethylene oxide on average, show less problems in gel formation, corresponding unsaturated fats alcohol ethoxylates, but also such components based on unsaturated C 16/18 fatty alcohols.
- a large number of soluble, but possibly insoluble at low temperatures, detergent active components are easy to incorporate and dissolve in pasty to dough-like formulations.
- Examples include alkylbenzenesulfonate, nonylphenol ethoxylates, a maximum of about 30% FAES solutions, saturated fatty alcohol ethoxylates based on C 12/14 or C 12/18 fatty alcohol with an average of 5 to 7 mol ethylene oxide, unsaturated fatty alcohol ethoxylates based on C 16/18 -Fatty alcohol with 5 to 9 moles of ethylene oxide, short-chain alkyl glycosides, oxo alcohol ethoxylates based on C 12/15 -Oxo alcohols with 5 to 9 moles of ethylene oxide, amphoteric surfactants, but for example also largely insoluble disalts, especially sodium disalts of alpha-sulfofatty acids with predominantly C 16 / at room temperature 18 fatty acid in the fatty acid residue.
- Water-soluble and / or water-swellable organic and / or inorganic additives which can be surfactant or non-surfactant in nature, are suitable as dispersing agents for surfactants or surfactant combinations which cause difficulties from the point of view of poor solubility and / or gelling.
- Gelling tendencies of the detergent concentrates can often be easily counteracted, for example, by using limited amounts of water-soluble inorganic salts. Examples of these are sodium sulfate and / or sodium chloride.
- the combination of poorly soluble surfactants in a mixture with readily soluble surfactants can reduce the dissolving behavior of the paste or dough-shaped packaging are substantially influenced.
- disalted dispersions can be of great importance as versatile dispersing aids.
- limited amounts of disalt which are approximately in the range from 5 to a maximum of 50% by weight, preferably in the range from 5 to 25% by weight, based on the mixture of sparingly soluble surfactant + disalt, are sufficient to to ensure a clearly accelerated dissolving or dispersing behavior for the pasty preparation.
- Dimensionally stable detergent concentrates which can preferably be used according to the invention can also be determined by their viscosities.
- the upper viscosity limit values are around 1 million mPas - determined with the Brookfield Helipath.
- Materials with a consistency of significantly higher viscosities - e.g. B. in the range of 2.5 million mPas or above - are characterized by a very slow dissolution behavior.
- the lower limit lies in the area of the lotions which are still sufficiently dimensionally stable, as are known, for example, from the area of hand-washing pastes.
- the value of about 12,000 to 15,000 mPas (Höppler viscometer) at room temperature is to be specified.
- Pastes are particularly suitable which show viscosity values in the range from about 15,000 to 300,000 mPas and preferably not more than about 200,000 mPas at room temperature (Höppler viscometer).
- the detergent preparations according to the invention contain, in addition to the detergent surfactants, other customary detergent components such as organic and / or inorganic builder components, detergent alkalis, soil-carrying compounds, enzymes, brighteners, fragrances and / or dyes and the like.
- other customary detergent components such as organic and / or inorganic builder components, detergent alkalis, soil-carrying compounds, enzymes, brighteners, fragrances and / or dyes and the like.
- the procedure is as follows:
- the textile material to be washed is put into the machine as dry material or as a moistened to dripping wet material.
- the required amount of paste or dough detergent concentrate is added to the textile. It may be advantageous to change the detergent concentrate to a white and / or colored one apply a real piece of textile that contains markings for the correct dosage of detergent depending on the hardness of the wash water (see Figure 1). If desired, the gel or pasty detergent concentrate can also be added to the textile to be washed in such a piece of textile.
- the largely dimensionally stable consistency and the paste or dough properties of the concentrates used according to the invention generally ensure that there is no undesired premature diffusion of the detergent concentrate into limited textile areas.
- This advantage is even more pronounced in that when water enters, even under the conditions of textile mechanics, there is a delayed dissolution of the paste-like or dough-like detergent concentrate in the aqueous phase, so that the risk of local over-concentrations being significantly reduced. This can be important, for example, in cases in which the formation of spatially limited defects must be feared due to over-concentrations of detergent ingredients.
- the wash liquor is built up by gradually adding water to the textile material containing detergent concentrate.
- the duration of the treatment of the textile material under washing conditions in the machine is extended in the process state which is characterized by the amount of water or washing liquor which approximately corresponds to the dripping wet textile material in the machine filling.
- conventional machine washing works with a quantity of liquid which corresponds to a multiple of this dripping wet state.
- this can dripping wet need an amount of water that corresponds to about 2 to 3 times the dry weight of the textile.
- the amount of water entered corresponds to about 2 to 4 times the dry weight of the textile. If, under these conditions, the wetting process is extended, in particular with the textile being circulated, before the more dilute final concentration of the detergent solution is adjusted by adding more water, the wetting will accelerate rapidly and the cleaning action will accelerate. It may be preferred to use this process period for at least a few minutes, e.g. B. for the range of about 5 to 15 min. expand.
- the treatment of the textile goods in this process stage - but of course also in all other stages of the automatic washing process according to the invention - can take place at room temperature or can be promoted by using elevated temperatures.
- the method according to the invention can be carried out in all customary machine types, in particular in known household washing machines with a horizontally arranged drum which are to be loaded from the front or in washing machines to be loaded from above.
- the method according to the invention is particularly suitable for the use of washing machines in which the moist to dripping wet textile material is heated by the action of microwaves on the dampened textile material.
- This heating of the wet textile material can be used in the wetting or washing process step with the washing liquor formed in situ and / or to promote one or more washing-out steps.
- a washing process using Microwave is particularly suitable for the previously described embodiment of the method according to the invention, in which the stepwise construction of the wash liquor is carried out and a treatment step which takes at least a few minutes, preferably about 3 to 15 minutes, is provided, in which the amount of water is about 2 to 4 times, preferably corresponds to about 2 to 3 times the dry weight of the textile.
- the amount of water in the wetting stage in the sense given above is limited to at most approximately dripping wet textile, the usual target dosage of detergent or detergent mixture is nevertheless achieved which provides conventional textile washing, working temperatures in the range of room temperature or only moderately elevated temperatures.
- microwave is a suitable measure for this embodiment of the method according to the invention which requires only limited amounts of energy, but the invention is in no way limited to this.
- the desired entry of thermal energy can also be done in other ways, for example by introducing steam - and the associated release of the latent heat of vaporization in the steam condensation - and / or by other forms of energy radiation, for example IR radiation.
- Appropriate preparations with viscosities (Höppler viscosity at room temperature) of at least about 70,000 mPas and preferably of at least about 100,000 mPas are particularly suitable for producing storage-stable heterogeneous detergent formulations in paste, gel or dough form.
- the paste or gel state or the dough-like state of the detergent formulations used according to the invention is adjusted in a manner known per se by using water and / or organic, preferably water-soluble solvents, provided the active substance combination as such is too solid or vice versa by restricting the content the formulations on these liquid components and / or by the use of thickeners, if the detergent composition is too thin.
- Suitable thickeners are, for example, natural polymer compounds such as carboxymethyl cellulose or methyl cellulose, guar compounds and the like, as well as synthetic poly Mercury components, for example of the type of polyacrylates and / or polymethacrylates, which can also be partially crosslinked.
- surfactant components with a thickening effect are particularly suitable for thickening excessively flowable detergent mixtures.
- examples include soaps and solid or sparingly soluble surfactant components, in particular corresponding anionic and / or nonionic surfactants.
- use can also be made of the known gelling tendency which occurs when small amounts of electrolyte salts are added to aqueous solutions of selected surfactants, in particular those based on fatty alcohol ether sulfates.
- Other suitable thickeners are swellable layered silicates of natural and / or synthetic origin, which, as is known, can also develop their own effects in the context of textile washing.
- the largely dimensionally stable detergent formulations used in paste or gel form or also in the form of a dough are preferably set to pH values in the neutral to moderately alkaline range, in particular thus in the range from about 7 to 12, preferably in the range from about 7 to 10.
- Suitable washing alkalis and / or neutralizing agents are suitable for regulating the pH value based on citric acid.
- the pH is determined on 1% aqueous solutions.
- Such a detergent has the rheological properties required for dosing by means of a dispensing cloth while maintaining the required high degree of reliability of the detergent concentrate and excellent detergency.
- the convenient handling of the dosage is also advantageous.
- the paste-like detergent concentrate is applied to a white or color-fast piece of textile as a dispensing cloth with markings for the strand length of the detergent paste required for a washing machine filling, and, if desired, the detergent is encased therein. If necessary, the markings take into account the water hardness of the wash water and the strand cross-sections caused by the tube outlet openings.
- An example of the dispensing cloth mentioned is shown in the figure ( Figure 1).
- pastes 1 and 2 Two paste formulations of detergent which are no longer flowable at room temperature are compiled in accordance with the following information.
- the numerical values for pastes 1 and 2 summarized in Table 1 below are percentages by weight, based on the pasty detergent mixture.

- the pastes are produced in detail as follows: water and triethanolamine are introduced, the fatty acid is dissolved in the liquid phase at approx. 50 ° C, then the surfactant components are stirred in. Finally, the remaining components, including the water-miscible organic solvents used in the case of Example 2, are added.
- the paste of Example 1 shows the value of 218 750 mPas in the determination of the viscosity with the Brookfield-Helipath RVF (spindle T-E, 4 rpm).
- a standard liquid detergent from the trade is used in a conventional manner in the washing-up chamber of the machine in corresponding washing tests.
- Table 2 summarizes the reflectance values obtained when washing with the pastes according to the invention from Examples 1 and 2 and combined with the corresponding values in comparative washing tests with the standard liquid detergent.
