Description

Conditioning of textiles

The present invention relates to the conditioning of textiles made from cotton _} synthetic fibers or mixtures, which can also be made iron-proof. The conditioning improves the softness of the textiles and reduces their tendency to become electrostatically charged.

It is well known, textiles, yarns, threads, finished clothing and the like in the most varied production stages and subsequent work steps to be treated to achieve certain properties. The mixtures used for such treatment are offered in a wide variety of forms, for example as emulsion and spray mist, with these at different temperatures and under different working conditions to obtain the best treatment can be used. This also includes the application of softening agents and anti-static agents

Means and, for example, the treatment of laundry in washing machine during washing or rinsing.

The calibration of laundry inside a tumble dryer has already been proposed, such as the spraying of plasticizer on V / äs before or in the Interior of a dryer. In addition, atomization devices in the dryer and aerosol spray mist have been used to prevent V / aes treat with germicides, starch and other products to improve properties.

These methods, which were successful in many cases, had considerable disadvantages, so that efforts were made to use the conditioning method to improve. The present invention is based on the surprising finding that the application of Foam on laundry and subsequent agitation of the same results in an improved conditioning process. Although one would have to assume that the use of a foam of the conditioning agent would be ineffective because of the Deposition of too much conditioning material on certain areas of the textiles treated in this way and because of the poor distribution of conditioning agent on all textile surfaces, surprisingly turned out to be exactly the opposite especially when using stable foams. Such products can be easily apply, distribute lightly over the entire fabric of the laundry if it is tumbled in a dryer,

209833 / 1U3 ^BAD original

no stains are produced even with cationic conditioning agents and subsequently ironed non-iron laundry.

According to the invention, a method for conditioning textiles is proposed, which consists in applying a foam mixture from a pressure vessel to the textiles, which foam mixture contains a foam agent, a textile conditioning agent, a normally gaseous propellant and water, whereupon the foam is poured over the Surface of the textiles distributed by turning them over.

The foaming agent used is preferably an anionic or nonionic surfactant, such as triethanolamine ßearate or polyoxyethylene lauryl ether which is stabilized with cetyl alcohol; the fabric conditioning agent can be an amphoteric or cationic calibrating agent such as a complex fatty amido compound or a quaternary ammonium halide; the propellant is preferably an organic liquefied gas, such as a mixture of chlorinated and / or fluorinated hydrocarbons, v; whether the treatment is preferably carried out on cotton or non-iron textiles made of synthetic fiber in an automatic laundry dryer. The mixture used is containing under pressure located emulsion containing suitable proportions of the components mentioned.

209I33 / 1U3 _BAD original

The invention also encompasses the valved pressure vessels, the conditioning mixture and the one produced finished foam.

The softeners used for textiles are Products that improve the "feel" of the fabric and generally make it softer, as well as the electrostatic Charging is reduced, especially with synthetic textiles. When textiles dry with agitation such as in automatic tumble dryers, the laundry becomes somewhat through the mechanical tumbling softer, but an electrostatic charge occurs, especially in synthetic fabrics, which means these often wrinkle or cause an electrical discharge when they are removed from the dryer. When textiles If these products are not washed with soap but with conventional detergents, less lipophilic materials remain due to the greater cleaning effect of these products back on the textiles, so that, despite the fact that the laundry dries through, it often becomes hard or stiff.

It has been found that the laundry becomes much softer and shows less static charging, if you put small amounts on the surface of such ashes applied by plasticizers. The best results in terms of softness in cotton textiles and in terms of reducing the electrostatic charge synthetic textiles and blended fabrics, like both

209913/1143 _{MD 0RI} ginal

for example nylon, dacron or blended fabrics made of polyester / cotton, such as blends in a ratio of 65:35, the wrinkle-free or non-iron have been made.

Although there are numerous surfactants that improve both plasticization and To highlight the antistatic properties of the textiles, the best results are usually with cationic ones or amphoteric fabric softeners achieved. The cationic products are excellent plasticizers and anti-static prevention agents; however, some of these compounds tend to to produce greasy or oily stains on the treated material if they are in excessive concentration or excessive amounts are used. Such stains mostly occur on colored laundry and especially on synthetic textiles, such as mixed fabrics made of cotton and polyester fibers. This staining is particularly clear when it comes to textiles that have been made crease-resistant or that are non-iron. There is therefore a great need for products that do not simultaneously cause staining during conditioning do the laundry.

Quaternary ammonium compounds are suitable fabric softening agents, also quatern.'ire Phosphoniunisalzo. These

209833/1 U3 _BAD

Quaternary compounds contain several lower alkyl radicals on the quaternary atom, for example on nitrogen, and one or two higher alkyl or benzyl radicals or corresponding remains. The salt-forming ion is preferably a halide, such as chloride or bromide, but can also be another, solubilizing group. Preferably distearyldimethylammonium chloride or a other quaternary compounds of similar effectiveness are used, such as cetyltrimethylammonium bromide, dimethyldilaurylammonium chloride, Diethyl distearyl ammonium chloride, Dimethyldi (hydrogenated tallow alkyl) ammonium chloride, stearyldimethylbenzyl ammonium chloride and laurylmethyldibenzylammonium bromide. Furthermore, a wide variety of cationic Compounds used v / earth, such as alkylpyridine salts, alkylimidazolines, higher alkylamines, namely primary, secondary or tertiary compounds, higher alkylguanidine salts, such as, for example, 1-methyl-1-sterarylaminoethyl-2-stearylimidazoline methosulfate, Stearyl pyridine halides, cetylisoquinoline bromide and alkyl morpholine chloride. Both cases mentioned, the lower alkyl radicals have 1 to 5 and preferably 1 to 2 carbon atoms, while the higher Alkyl radicals have 1 to 20 and preferably 12 to 18 carbon atoms. Although one uses mixtures of cationic Plasticizers or antistatic products with non-ionic or amphoteric plasticizers Mixtures with anionic compounds are usually avoided because of chemical reactions.

209833/1 U3

Currently the most suitable amphoteric conditioning agents are complex pettamido compounds, such as Soromine, such as Soromin AT and Soromin AL. Other amphoteric compounds that are primarily cationic when used Properties show are higher alkyl-ß-alanines, N-alkyltaurines with higher alkyl radicals, such as the reaction product of laurylamine with sodium isethionate, N-alkylaspartic acids with higher alkyl radicals and miranols. Other suitable compounds are zwitterion surfactants such as betaines and similar detergent-active compounds form internal salts.

Suitable non-ionic surfactants that can be used as fabric softening are, inter alia Polyoxyalkylenalkyläther, such as the Polyoxyäthylenlauryläther with ¹ J Äthoxyresten (Brij 30), Alkylphenoxypolyalkoxyalkanole such as Nonylphenoxypolyäthoxyäthanol (Igepal CO 880) and balanced hydrophilic / lipophilic compounds can be obtained by condensation of lower alkylene oxides with an organic hydrophobic material, such as, for example, the ¹ Pluronics. The nonionic softeners usually contain lipophilic radicals with higher alkyl components of generally 8 to PO carbon atoms and hydrophilic components, such as polyalkylene oxides, which usually contain 20 moles of alkylene oxide per mole. The lower alkylon oxides usually have 2 to carbon atoms and are preferably ethylene oxide.

209I33 / 1U3

Other suitable non-ionic plasticizers are Amine oxides and alkanolamides. The former are usually alkylamine oxides with higher alkyl groups and two lower ones Alkyl radicals, the higher alkyl radical having 8 to 20 carbon atoms and the lower alkyl radical 1 to 4 carbon atoms and are preferably methyl radicals. The alkanolamides can be mono-, di- and trialkanolamides of higher fatty acids, such as myristic acid diethanolamide, palmitic acid monoethanolamide, etc.

The anionic surfactants, which can be used as conditioning agents, i.e. to soften and reduce electrostatic charge, are water-soluble salts, e.g. soluble salts of organic sulfuric acid reaction products, which have an alkyl radical of 8 or 10 to about 18 or 20 carbon atoms and either a sulfonic acid - or have sulfuric acid ester residue. This also includes the corresponding compounds that contain acyl residues of similar chain length. Typical representatives of these compounds are higher alkyl sulfates having 18 to 20 carbon atoms, higher alkylbenzene sulphonates, particularly linear alkylbenzene sulphonates having from 10 to 18 and especially 12 to 15 carbon atoms in the alkyl radical, higher Fettacyltauride and -isäthionate, higher fatty acid monoglyceride sulfates and sulfonates, äthersulfonate higher Fettglycerin-, Schwefelsäureester of reaction products of 1 mole of a higher fatty alcohol with 1 to 6 moles of a lower alkylene oxide and alkylphenylalkylene oxide ether sulfates

209833/1143

with lower alkylene radicals containing 1 to 10 moles of a lower alkylene oxide per molecule. Typical examples of these compounds are Natriumtalgalkoholsulfat, sodium alcohol sulfate from hydrogenated tallow, sodium lauryl sulfate, triethanolamine n-hexadecyl, Trimethylamincetylsulfat, potassium-n-octadecylsulfonate, Natriumkokosnußölfettsäuremono glyceridsulfat, sodium n-do decylbenzenesulfonates, Natriumtetradeeyltoloylsulfonat, Nonylphenylpolyoxyäthylensulfat, with 5 moles of ethylene oxide, Matriumdodecylglycerinäthersulfonat and Potassium oleyl-N-methyltauride. These compounds can be used alone or in admixture.

In addition to the synthetic anionic organic detergents, water-soluble soaps of higher fatty acids can be used. These are mostly alkali salts of higher fatty acids with 8 to 20 and preferably 12 to 18 carbon atoms, which come from natural products , such as coconut oil, palm oil, corn oil, tallow and mixtures thereof. Trialkanolamines and trialkylamine salts such as triethanolamine soaps can also be used. In addition, other soluble soaps can be used for the present purpose . Examples of such products are the sodium soaps of an 85:15 mixture of tallow and coconut oil fatty acids, the potassium soap of stearic acid, mixed sodium and potassium soaps of a 50:50 mixture of tallow and coconut oil fatty acids, sodium "cocate", potassium stearate , triethanolamine stearate and sodium laurate .

209833/1143

In addition to the water-soluble salts, the water-insoluble salts of calcium, magnesium, lithium can also be used and other heavier metals that make water-insoluble soaps. Generally will however, the appropriate water-soluble products are used, which are easier to get into when pressurized Allow mixtures to be processed.

The anionic compounds used are preferably higher alkyl sulfates or water-soluble soaps of higher fatty acids, such as hydrogenated tallow alcohol sulfates, usually the sodium salt, and sodium coconut / tallow soaps with a content of 85 % tallow and 15 % coconut oil soaps, preferably 1 part of the sodium, for example 10 until Ί0 % _{t are} replaced by potassium.

Other plasticizers and agents to prevent the electrostatic charges are described in "Detergents and Emulsifiers", 1969, Annual Edition, by John V /. McCutscheon, Listed where the various surfactants as anionic, cationic, non-ionic and amphoteric Compounds are listed, including those compounds with good conditioning properties. Here are the higher ones Listed alkyls having 8 to 20 carbon atoms and lower alkyls having 1 to Ί carbon atoms, the preferred Compounds mostly higher alkyls with 12 to 18 carbon atoms and lower alkyls with 1 to 2 carbon atoms own.

The foaming agents used in the present mixtures and in the process according to the invention can be very diverse Be compounds that in the presence of conditioning agents water and propellants and other ingredients the mixture result in a suitable foam that can be applied to the textiles to be conditioned. The foam produced should be such that when it is dispensed from a conventional pressure vessel with preferably a foam-generating dispensing valve is firm enough to last for at least about 5 minutes. One of those Foam is not broken up into small particles like a spray, but forms on a surface after spraying, a mass consisting of the conditioning agent and incorporated gas. The foam produced is much stronger and more dimensionally stable than, for example, a shaving foam dispensed from an aerosol container; he retains its shape as long as it is not directly influenced mechanically by impact or friction. In some In some cases, a softer or weaker foam can also be used, although this does not have the desired stability possess, provided that these softer foams adhere together sufficiently to be in this coherent form on the Textiles to be applied.

The foaming agents used to produce such foams can be a wide variety of surfactants including soaps and synthetic detergents.

209833/1143

Although amphoteric or cationic surfactants can be used for this purpose, that is by means of these surfactants generated foam too open-pored to form sufficiently coherent foams, so that preferably anionic or nonionic surfactants can be used, with anionic surfactants generally being better. The non-ionic However, surfactants together with foam stabilizers also give satisfactory foams. Such stabilizers can also be used with other surfactants to improve foam power.

Typically, to get the best products, use a softening and / or conditioning agent Electrostatic prevention and a different foaming agent to give the product the desired physical To maintain shape. However, a single product can also be used for both punctures. For example Triethanolamine stearate has both foam properties and conditioning properties and a mixture with This compound, water and propellant, has the desired conditioning properties and forms one good foam. If a single compound is to act as a conditioning agent and foaming agent, that compound will usually used in amounts which correspond to the sum of the amounts of the individual components otherwise used would.

209833/1 U3

The anionic foaming agents are the most varied of anionic surfactants previously described, also known as Conditioning agents work. A list of these products is in the McCutcheon publication referenced above and reproduced in "Synthetic Detergents" by Schwartz, Perry and Berch (1968 Interscience Publishers). If necessary, an additive such as higher fatty alcohols can be used to increase the stability of the anionic foams and natural and synthetic gums, can be added.

Good foams based on anionic surfactants are obtained with the higher fatty acid soaps, preferably water-soluble soaps, but also with the water-insoluble soaps and the sulfur reaction products. The soaps are derived from higher fatty acids having 8 to 20 and preferably 12 to 18 carbon atoms and are derived essentially from natural oils or fats. Alkali, alkaline earth, amine, lithium, heavy metal and alkanolamine soaps can be used, with the alkali soaps and alkanolamine soaps being preferred. The alkanolamine can be a mono-, di- or trialkanolamine which generally contains 2 to k carbon atoms, preferably 2 carbon atoms, triethanolamine being preferred. When using triethanolamine, triple-pressed stearic acid, a mixture of palmitic acid and stearic acids, is used as the preferred fatty acid. Instead of triethanolamine stearate or other alkanolamine stearates, the

209833/1 U3

various other soaps can be used alone or in a mixture with the alkanolamine soaps. By changing the soap mix or a mix of soap with other anionic or non-ionic foaming agents, the properties of the final foam can be regulated. Instead of triethanolamine stearate, other alkanolamine soaps and alkali soaps, preferably sodium or mixed sodium / potassium soaps of higher fatty acids, such as soaps based on 20 % coconut oil and 80 % tallow, can be used.

The organic sulfur reaction products are known surfactants, which are the hydrophobic part of the molecule Is alkyl, aryl, arylalkyl or alkylaryl, while the hydrophilic part is a sulfonate or a sulfate. at In this compound, the aryl radical is generally a phenyl radical and the alkyl radical is a higher alkyl radical with 8 to 20 carbon atoms. In some foaming agents, the alkyl radical of the alkylaryl group is a lower alkyl radical or a polyalkyl radical with 1 to '(carbon atoms. Examples suitable foaming agents are sodium tallow alcohol sulfate, triethanolamine tallow alcohol sulfate, sodium monoglyceride sulfate, Potassium dioctyl sulfosuccinate, sodium lauryl sulfonate, sodium tetradecylbenzenesulfonate and their water-soluble ones Salts.

Although the mentioned water-soluble soap and synthetic

209833/1 U3

Surfactants are preferred foaming agents, they can be partially and sometimes completely replaced by water-insoluble soaps , such as alkaline earth, lithium and heavy metal soaps, which bring about a desired thickening effect in these mixtures. In general, the amount of insoluble soaps that are used to aid foaming is kept smaller than the amount of the other foaming agents, since they remain on the treated fabrics, which is not always desirable.

To achieve the desired foam, liquefied propellant gases are used as they are generally known, such as, for example, lower aliphatic or cycloaliphatic hydrocarbons or their chlorinated or fluorinated derivatives, such as propane, isobutane, cyclobutane, Freon, Genetron, Ucon, which are also known as Propellant 11 , 12, 113, UM, 21, 22 etc. denotes v / earth. Preferred are fluorinated ;; Hydrocarbons or chlorinated and fluorinated hydrocarbons which may contain free hydrogen atoms and are essentially hydrolysebest'indig. Such compounds are generally harmless and non-flammable. In general, the propellant gases are used in mixtures.

Pressure in a range between 1.4 and 4.9 kg / cm is a mixture of dichlorodifluoromethane and dichlorotetrafluoroethane. Furthermore, other compressed gases and liquids can also be used, such as nitrogen, carbon dioxide, nitrogen oxide, and similar blowing agents can also be used to influence the foam properties. In general, demineralized water is used with a hardness below 20 ppm, measured as calcium carbonate, and preferably water with less than 5 ppm.

209833/1 H3

Ordinary tap water can, however, be used, with water with a low hardness of, for example, below 50 ppm is preferred, although hard water up to 250 ppm and higher can be used.

In addition to the main components of the mixture according to the invention, various additives can be used, for example fragrances, bactericides, fungicides, optical brighteners such as aminostilbenes, usually in small amounts, for example up to 1 l and generally not more than 5 % of the total mixture. Optical brighteners which, when used in small amounts, show a noticeable effect on the laundry being treated are particularly suitable here.

Furthermore, other additives can be used to improve the foam quality and the exit properties of the To improve mixtures. Natural and synthetic gums and resins can be used to thicken the dispensed Emulsion can be used, whereby the delivery rate is reduced and is more controllable, the released liquid on first contact with an area of reduced pressure stabilizes and so does the foam the levy is stabilized. As the resins, there can be used polyvinyl pyrrolidone, polyvinyl alcohol, polyacrylamide and many other synthetic resins, organic gums such as guar gum, carrageenan gum, sodium alginate, caseinates and cellulose

209I33 / 1U3

derivatives such as sodium carboxyraethyl cellulose and hydroxypropylmethyl cellulose be used. If gelation of the mixture occurs in the container or if a dilution of the mixture is desired, hydrophilic solvents such as polybasic alcohols such as for example propylene glycol, glycerine and other dibasic and polybasic alcohols can be used. In In some cases, polyethylene glycol, such as Carbowax ^ 00 uses Kerden. In addition to preventing gel formation, these substances help keep it more even Foaming and also improve foam quality and foam stability.

Other important additives, in particular for improving the appearance of non-ionic foaming agents, are the Foam stabilizers that can also be used with anionic, cationic or amphoteric components. Such compounds can be higher alcohols, especially higher aliphatic monobasic alcohols such as straight-chain saturated alcohols having 12 to 18 carbon atoms, such as Be cetyl alcohol. These stabilizers are often viewed as part of the foam concentrate itself as they are often added to keep the foam stable and together with the non-ionic compounds a stable foam to make it possible at all. If these compounds are omitted, the product dispensed will sometimes be aqueous or is in spray form. In addition to cetyl alcohol, other equivalent alcohols, such as stearyl alcohol,

209833/1 U3

Myristyl alcohol and mixtures of these alcohols can be used.

The proportions of the various ingredients depend on the results desired and, in particular, on whether the product is to be delivered in the form of a stable foam .

The foaming agent is generally used in an amount of 0.5 to 15 % (without stabilizer) and preferably in an amount of 2 to 10 %, for example when using triethanolamine stearate . The conditioning agent is present in an amount of 0.5 to 15 % and, when using Soromine AT (amphoteric fatty amide), for example, is 1 to 10 % of the end product. If the same product is used for both the foaming agent and the conditioning agent, this is used in amounts of 1 to 30 % . The blowing agent mixture, usually a larger amount of high-pressure blowing agent and a minor amount of a low-pressure propellant or diluent is used in amounts of 10 to 79% and preferably ¹ IO to 79%, usually in amounts of * J0 to 60%. In many cases the propellant mixture is 50 % of the total product. At such concentrations, in particular in the range between 40 to 60 % , an extremely stable foam is obtained, which often retains its shape for several hours beyond the generally desired minimum time of 5 minutes

209833/1 U3

maintains. Some of the mixtures described with lower proportions of propellants do not have the Desired stability, but can still be used according to the invention.

The water makes up the remainder of the mixture when there are no other ingredients left; usually the water content is from 20 to 50 and especially 25 to 45 JS.

The amount of foam stabilizer used, which is used with the nonionic foaming agent, is usually between 0.2 to 10 and especially 0.5 to 5 %. Similar amounts can be used with cationic, amphoteric and anionic foaming agents, although foam stabilizers such as cetyl alcohol are not needed with anionic surfactants, especially soaps such as alkanolamine soaps. To thicken the mixture and adjust the release properties and foam strength and stability, thickeners or resins are used in amounts of 0.2 to 5 % and often in amounts of 0.3 to 2.0 %, as is the case with polyvinylpyrrolidone. On the other hand, if the mixture is too thick or gels on storage and is therefore difficult to dispense, a diluent such as polyethylene glycol, glycerin, Carbowax and the like is generally used in amounts of 1 to 10% by weight of the final product.

209833/1 U3

For example, if the content of triethanolamine stearate is greater than 10 % of the aqueous phase of the mixture, the product can gel, so that in these cases about 5 % glycerol or polyethylene glycol should be added.

The mixtures according to the invention can be produced very easily. It is enough for all the ingredients except the propellants, to mix, to mix them at room temperature and, if necessary, to heat them up so that a forms a homogeneous mixture. The various soaps can be made in situ. For example, you can use triethanolamine stearate produce by using triethanolamine and stearic acid first or later mixed together with the mixture. In general, the mixture does not need to be to be heated to temperatures above 50. Fugitive Additives such as perfume are appropriate accordingly added later.

The mixture is then given into the pressure vessel, which is closed and usually via the valve with the propellant is pressurized. When using several propellants, the individual components can be sequential or are preferably added as a mixture. The desired valve can then be attached.

The use of the product is extremely simple and done

209833/1 143

by actuating the valve and dispensing the desired amount of conditioning agent, sometimes it is convenient to shake the aerosol container before use to achieve a more even mixture. The foam generated can be placed directly on the textiles to be conditioned or can be placed in the hand or in a suitable container, from where the foam is then transferred to the textiles, for example by adding the foam to damp laundry in a tumble dryer. Such laundry usually contains 20 to 70 % water. The treatment can also be carried out on dry laundry or on textiles that are not in an automatic clothes dryer, but this is generally not so convenient.

The conditioning mixture is usually used in amounts of 5 to 10 and preferably 10 to 50 and especially 20 g per ^{liter of} dry laundry. These are quantities suitable for handling and packaging. Of course, the amount to be used depends on the effectiveness of the conditioning mixture and the amount of the actual conditioning agent is adjusted in the overall mixture in such a way that the desired amount of end product is used. The quantities given relate to the mixture dispensed from the container. Since part of the propellant escapes when the agent is dispensed, the weight of the foam applied is approximately up to 10 % less than the weight of the total

209833 / 1U3

dispensed amount. This is especially true with a stable foam that occurs within the 5-minute period does not lose its shape when standing. It is useful if the propellant remains in the foam because it appears to be contributes to the stability of the foam and the deposition of the conditioning agent on the surface that supports textiles better than would be the case with an unstable or liquid foam.

Although the stable foam retains its shape for a long time, provided it is not exposed to external forces it is usually broken open in an automatic tumble dryer when the laundry is too damp or distributed and divided over the surface of the laundry after 1 to 5 revolutions of the drying drum. Such a one Drum usually rotates at a speed of 10 to 60 revolutions per minute, with drying air from Room temperature up to 200 C is used. In general the laundry is circulated for 5 to 60 minutes during such a drying process. Under these conditions it spreads the foam preferably in connection with the moisture present in the tissue to be treated over the whole The surface of the textiles to be treated makes them soft and antistatic. If the effect is not sufficient, so the composition can be modified to include more conditioning agent or a greater amount of the mixture can be used.

209833/1 U3

The advantages of the present invention are that a practical product is proposed, the conditioning or softening of laundry is satisfactory without having to go to the washing machine again. When the washed fabrics after the rinse and spinning is placed in the tumble dryer while it is still damp, the housewife only needs the top of the laundry Apply the required amount of conditioning agent as foam, close the drying drum and wash the laundry to leave the drying process. The laundry is automatically conditioned here. The housewife also sees this the amount of foam applied and can visually estimate how strong the conditioning is. Different than with the use of sprays, where optical dimensioning is not possible, can be used in the present If the housewife can rely on the recognizably dispensed product or can count the time during which she does the Keeps dispensing valve open. The product cannot be sprayed in the air or returned to the user will. The laundry is softened without staining, which is surprising since one would expect the foam to penetrate the fibers or adhere to the textile surface and leads to staining due to excessive concentration.

In the following, the invention is to be explained in more detail by means of examples, all quantitative data being based on weight relate.

The above compositions are prepared by the individual components without perfume, water. and propellant mixed in water at room temperature, the mixture heated to 50 ° C, cooled, the Add perfume and then place the mixture in a pressure vessel which is then pressurized with propellant in the usual way. The product can be shaken in the container to form the emulsion and then packaged.

The individual mixtures were examined by g after shaking of the pressure vessel 20 kg of the product to be tested on H laundry muster containing approximately 3 kg of water. Half of the test laundry consisted of cotton and half of synthetic textiles. The textiles included non-iron textiles made of polyester / construction wool mixtures in an amount ratio of 65:35, with the greater proportion of the synthetic laundry consisting of Dacron and nylon. Some of the non-iron laundry was light blue in order to be able to better identify oily deposits, especially after heating or ironing. The conditioning agents were applied as foam to the textiles in the drying drum within 2 minutes of removing the laundry and usually immediately afterwards. Immediately after the addition, drying was started, with a drying gas of 70 ^° C. and one revolution of the

209833/1 U3

Drying drum of 30 rpm. ! - 1 to 2 revolutions of the The foam had mixed with the textiles and was distributed during the subsequent drum Drying more and more on the VSsehe. It was overall * Dried for 5 minutes.

All mixtures of the above examples were applied in an amount of 20 g per ^l kg of V.Msche and resulted in an excellent antistatic effect and good softening of the fabric. In some cases, namely with compositions according to Example 2, 5> 6, 7 8 and 10, the effect was considerably improved if the amount used was increased to 100 g. With regard to foam stability, the products according to Example 3> 5 , 11, 12 and 13 are not very stable, while the other compositions are sufficiently stable and remain unchanged for 5 minutes without losing their shape The foam is so stable that it can be taken from one hand to the other hand several times without destroying the foam structure v / can earth.

Although the above compositions provide excellent conditioning of fabrics and surprisingly do not result in oily staining, the compositions can be changed accordingly. For example

209833/1143

the propellants used can be exchanged accordingly and use others for the high and low pressure propellants, such as Freon 11, 21, 22, 113, Octafluorocyclobutane, isobutane and the like without adversely affecting the properties of the product. Instead of Arquad R-'lO, Sulversoft WS-30, Soromin AL and Soromin AT can contain other cationic compounds of the type described above and others amphoteric compounds are used, for example one can use miramines, for example Miramine SH, Miranole, such as Miranol C2M and Deriphate, such as Deriphat 16OC, instead of the corresponding cationic compounds and arr.photeric compounds. A wide variety of nonionic compounds can also be used can be used, such as Pluronics, which can be used instead of the non-ionic compounds. A wide variety of anionic compounds can replace the soaps, e.g. magnesium or aluminum soaps. The proportions can also be changed, and resins, thickeners, thinners, Foam stabilizers are added or omitted, good products are always obtained. Further the proportions can be changed in order to achieve the softening effect and the antistatic treatment decrease or increase, with the occurrence of staining by changing the concentration or can be counteracted by adding release agents,
