Description

The present invention relates to a method for conditioning textiles, e.g. B. made of 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 generally known to use textiles, yarns, threads, and finished clothing in a wide variety of production stages and in subsequent work steps Achieving certain properties to treat. the Mixtures used for such a treatment are in the most varied of forms, for example offered as emulsion and spray, these at different temperatures and below the various working conditions to achieve the

ίο best treatment to be used. Which also includes also the application of plasticizers and antistatic agents and, for example, the Treating laundry in a washing machine while washing or rinsing.

is The softening of laundry inside a tumble dryer is already known, for example the spraying of softening agents onto laundry or into the interior of the dryer (cf. DE-OZ 20 21 561). In the older DE-OS 2122 764 is a Process for treating cloth or textile goods proposed in which the drum of the tumble dryer coated with a conditioning agent and then the textile material is circulated in this drum. There are also atomizing devices Used in the dryer and aerosol spray to wash with germicides, starch and other products to improve properties to treat.

These known methods have considerable disadvantages, so that there was a desire to use the conditioning process to improve.

The present invention is based on the surprising discovery that the application of Foam on laundry and subsequent circulation of the same is an improved conditioning process Although one had to assume that the stake a conditioning agent-containing foam would be ineffective because of poor distribution of the conditioning agent on all textile surfaces, was surprisingly accurate found the opposite, namely an excellent distribution, especially when one is stable Foams used Such products can be easily applied and distributed over the entire textile surface if the textiles to be treated are in be circulated in a dryer, even with

An anionic foam agent is preferably used as the foaming agent or nonionic surfactant used, such as triethanol

aminstearate or polyoxyethylene lauryl ether with Cetyl alcohol is stabilized; the fabric conditioning agent can be an amphoteric or cationic softening 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, the treatment being preferably on cotton or The non-iron fabrics made from synthetic fibers are used in an automatic tumble dryer Mixture consists of a pressurized emulsion, which appropriate proportions of the mentioned Contains ingredients

The softeners used for textiles are products that improve the "feel" of the fabric and generally make it softer electrostatic charge is reduced, especially with synthetic textiles. If textiles are not Movement to be dried, such as in automatic clothes dryers, the laundry will be slightly softer due to the mechanical fulling, but it often becomes electrostatically charged especially when it comes to synthetic fabrics, which often causes them to wrinkle or when Removing it from the dryer will result in an electrical discharge. If textiles are not soaped, but are washed with conventional detergents, remain due to the greater cleaning effect these products return less lipophilic materials to the textiles, so that the laundry can be washed in spite of the Full drying often becomes hard or stiff.

It was found that the "Vasche very much." becomes softer and shows less static charge if you put such small laundry on the surface Amounts of plasticizing agent applied will give the best results in terms of plasticizing with cotton textiles and with regard to reducing the electrostatic charge with synthetic textiles and blended fabrics, such as nylon, dacron or blended fabrics made of polyester / cotton, such as mixtures in the ratio of 65:35 that have been made crease-free or non-iron are.

Although there are numerous surfactants that both improve softening and improve Highlighting the antistatic properties of textiles will usually give the best results Cationic or Amphoteric Fabric Softening Agents The cationic products are excellent softening agents and anti-static agents; some of these However, compounds tend to leave greasy or oily stains on the material treated with them when used in excessive concentration or amount. Such Stretching mostly occurs with colored laundry and especially with synthetic textiles, such as for mixed fabrics made of cotton and polyester fibers. This staining is especially noticeable when there is are textiles that have been made crease-proof or are non-iron. There is therefore a great need on products that do not stain the laundry during conditioning.

Quaternary ammonium compounds are suitable fabric softening agents, as are quaternary phosphonium salts. These 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 radicals. That Salt-forming ion is preferably a halide, such as chloride or bromide, but can also be another, the Be solubility-inducing group. Preferably distearyldimethylammonium chloride or a other quaternary compounds of similar effectiveness are used, such as

Cetyltrimethylammonium bromide,

ίο dimethyldilaurylammonium chloride, Diethyl distearyl ammonium chloride, Dimethyldi (hydrogenated tallow alkyl) -

ammonium chloride, Stearyldimethylbenzylammonium chloride and

Laurylmethyldibenzylammonium bromide.

A wide variety of cationic compounds can also be used, such as alkyl pyridine salts, Alkylimidazolines, higher alkylamines, namely primary, secondary or tertiary compounds, higher alkyl guanidine salts such as

l-methyl-l-stearylaminoethyl-2-stearyl-

imidazcline methosulfate, Stearyl pyridine halides, Cetylisoquinoline bromide and

Alkyl morpholine chloride.

In the cases mentioned, the lower alkyl radicals have 1 to 5 and preferably 1 to 2 carbon atoms, while the higher alkyl radicals have 8 to 20 and preferably 12 to 18 carbon atoms.

Although one uses mixtures of cationic softeners or antistatic products with nonionic or amphoteric softeners Mixtures with anionic compounds are mostly used because of the chemical side reaction avoided.

The currently most suitable amphoteric conditioning agents are complex fatty amido compounds, for example products derived from triethanolamine. Other amphoteric compounds that when used primarily show cationic properties are higher alkyl-ß-alanines, with N-alkyltaurines higher alkyl radicals, such as, for example, the reaction product of laurylamine with sodium isethionate, and N-alkylaspartic acids with higher alkyl radicals. Other suitable compounds are zwitterion surfactants, such as betaines and similar detergent compounds that form internal salts.

Suitable nonionic surfactants that can be used as fabric softeners r <en are, inter alia, polyoxyalkylene alkyl ethers, such as for example the polyoxyethylene lauryl ether with 4 ethoxy radicals, alkylphenoxypolyalkoxyalkanols, such as for example nonylphenoxypolyethoxyethanol and balanced hydrophilic / lipophilic compounds, the obtained by condensation of lower alkylene oxides with an organic hydrophobic material such as the known addition products of ethylene oxide and polypropylene glycols. the nonionic plasticizers contain ge homely lipophilic residues with higher alkyl components th of generally 8 to 20 carbon atoms and hydrophilic components such as polyalkylene oxides, the usually contain 4 to 20 moles of alkylene oxide per mole. The lower alkylene oxides usually have 2 to 3 carbon atoms and are preferably ethylene oxide.

Other suitable nonionic plasticizers are amine oxides and alkanolamides. The former are usually higher alkyl amine oxides

and two lower alkyl radicals, the higher alkyl radical from 8 to 20 carbon atoms and the lower The alkyl radical contains 1 to 4 carbon atoms - preferably methyl radicals - The alkanolamides can Be mono-, di- and trialkanolamides of higher fatty acids, such as myristic acid diethanolainide, Palmitic acid monoethanolamide.

The anionic surfactants that can be used as conditioning agents are water-soluble salts, z. B. soluble salts of organic sulfuric acid reaction products, which have an alkyl radical of 8 or 10 to 18 or 20 carbon atoms and either one Have sulfonic acid or sulfuric acid ester residue. This also includes the corresponding connections, the acyl residues. similar chain length included. Typical representatives of these compounds are higher Alkyl sulfates having 18 to 20 carbon atoms, higher alkyl benzene sulfonates, especially linear alkyl benzene sulfonates with 10 to 18 and in particular 12 to 15 carbon atoms in the alkyl radical are higher fatty acyl taurides and isethionates, higher fatty acid monoglyceride sulfates and sulfonates, higher fatty acid ether sulfonates, Sulfuric acid esters of reaction products aas 1 mole of a higher fatty alcohol with 1 to 6 moles of a lower alkylene oxide and alkylphenyl alkylene oxide ether sulfates with lower alkylene radicals containing 1 to 10 moles of a lower alkylene oxide per molecule. Typical examples of these compounds are sodium tallow alcohol sulfate, sodium alcohol sulfate of hydrogenated Tallow, sodium lauryl sulfate, triethanolamine nhexadecyl sulfate Trimethylamine cetyl sulfate, potassium n-octadecyl sulfonate, sodium coconut oil fatty acid monoglyceride sulfate Sodium n-dodecylbenzenesulfonate, sodium tetradecylioloyl sulfonate, nonylphenyl polyoxyethylene sulfate with 5 moles of ethylene oxide, sodium dodecyl glycerol ether sulfonate and potassium oleyl-N-methyl tauride. These Compounds can be used alone or in admixture.

In addition to the synthetic anionic organic In detergents, water soluble soaps of higher fatty acids can be used. Here it is are mostly alkali salts of higher fatty acids with 8 to 20 and preferably 12 to 18 carbon atoms, which are derived from natural products such as coconut oil, palm oil, corn oil, tallow, and mixtures thereof. Man Trialkanolamines and trialkylamine salts, such as triethariolamine tires, can also be used. Furthermore, others can soluble soaps can be used for the present pressure. Examples of such products are the sodium soaps of an 85:15 mixture of tallow and coconut oil fatZuren, 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 5 :,

In addition to the water-soluble salts, the water-insoluble salts of calcium, magnesium, lithium and other heavier metals can also be used to make water-insoluble soaps. In general, however, the corresponding water-soluble products are used, which are easier to process in pressurized mixtures.

As the anionic compounds, higher alkyl sulfates or water-soluble soaps are preferably higher Fatty acids are used, such as hydrogenated tallow alcohol sulfates, mostly the sodium salt, and sodium coconut / tallow soap. with a content of 85% tallow and 15% coconut oil soaps, preferably part of the Sodium, for example 10 to 40%, is replaced by potassium

Other plasticizers and anti-static agents are in »Detergents and Emulsifiers, ”1969, Annual Edition, by John W. McCutscheon, listed where the various Surface-active substances as anionic, cationic, nonionic and amphoteric compounds are listed, including compounds with good conditioning properties. Here are the higher ones Listed alkyl radicals with 8 to 20 carbon atoms and lower alkyl radicals with 1 to 4 carbon atoms, the preferred compounds are mostly higher alkyl groups with 12 to 18 carbon atoms and lower Have alkyl radicals with 1 to 2 carbon atoms.

The foaming agents used in the process according to the invention can contain the most varied of compounds be in the presence of conditioning agents, water and propellants and other ingredients the mixture result in a suitable foam, which is applied to the textiles to be conditioned can be. The foam produced should be stable enough that it is dispensed from a conventional pressure vessel with preferably a foam-generating dispensing valve If it persists for at least about 5 minutes, such foam will not look like a spray in small particles are broken up, but instead forms a mass on a surface after spraying 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 keeps its shape, provided that it is not directly influenced mechanically by impact or friction. In some In some cases, you can use a softer or weaker foam, even if this is not the have the desired stability, provided that these softer foams adhere together sufficiently to be in this coherent form to be applied to the textiles.

The foaming agents used to produce such foams can have a wide variety of surface-active agents Substances, including soaps and synthetic detergents. Preferably anionic or nonionic surfactants are used, anionic surfactants generally being particularly preferred. the However, nonionic surfactants together with foam stabilizers also give satisfactory results Foams. Such stabilizers can also be used with other surfactants for improvement the foam power can be used.

Typically, an emollient conditioning agent is used to get the best products and / or to prevent electrostatic charge and a different foam agent to to obtain the product in the desired physical form. However, you can also use both functions use a single product. For example, triethanolamine stearate has both foaming properties also conditioning properties, and a mixture of this compound, water and propellant possesses the desired conditioning properties and forms a good foam. If a single compound is to act as a conditioning agent and foaming agent, this compound is usually used in such amounts as the sum of the amounts of the otherwise the individual components used.

As anionic foaming agents, the various

Most, previously described anionic surfactants are used, which also act as conditioning agents works. A list of these products is in the McCutcheon and in U.S. publication referenced above Contains "Synthetic Detergents" by Schwartz, Perry and Berch (1968, Interscience Publishers). Possibly can to increase the stability of the anionic foams an additive, for. B. higher fatty alcohols or natural and synthetic gums, may be added.

Good foams based on anionic surfactants are preferably obtained with the higher fatty acid soaps 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 conductive essentially from natural oils or fats away. It can be alkaline. Alkaline earth. Amine, lithium, heavy metal and alkanolamine soaps are used, the alkali soaps and alkanolamine soaps are preferred. The alkanolamine can be a mono-, Be di- or trialkanolamine, which generally has 2 to 4 carbon atoms, preferably 2 carbon atoms, contains, triethanolamine being preferred. When using triethanolamine is preferred Fatty acid triple pressed stearic acid, a mixture of palmitic acid and stearic acids, is used. Triethanolamine stearate or other alkanolamine stearates can be of the most varied types other soaps can be used alone or in admixture with the mkanolamine soaps. By change the soap mix or a mix of soap with other anionic or nonionic foaming agents the properties of the final foam can be regulated. Instead of triethanolamine stearate can use other alkanolamine soaps and alkali soaps, preferably sodium or mixed sodium / potassium soaps of higher fatty acids can be used. for example soaps based on 20% coconut oil and 80% tallow.

The organic sulfur reaction products are known surfactants, be; which the hydrophobic part of the An alkyl molecule. Aryl. Is arylalkyl or alkylaryl radical. while the hydrophilic part is a sulfonate or a Is sulfate. 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 is the alkylaryl group a lower alkyl radical or a polyalkyl radical with Ϊ to 4 carbon atoms. Examples of 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 salts.

Although the mentioned water-soluble soaps and synthetic surfactants are preferred foaming agents, they can be partially and sometimes completely replaced by water-insoluble soaps, such as for example through Erdaikaü, lithium and heavy metal soaps, which bring about a desired thickening effect in these mixtures. Generally will the amount of insoluble soaps used to aid lathering is kept less than the amount of other foam concentrates, as they are reflected on the treated textiles. what not always is desired.

To achieve the desired foam, liquefied propellant gases are used as they are generally known, for example lower aliphatic or cycloaliphatic hydrocarbons or their chlorinated or fluorinated derivatives, such as propane, isobutane, cyclobutane, aliphatic chlorofluorocarbons, e.g. B. difluorodichloromethane, trichloromonofluoromethane and mixtures thereof or a mixture of 15% dimethyl ether, 10% CFCIj and 75% CF ₂ CI ₂ . Fluorinated hydrocarbons or chlorinated and fluorinated hydrocarbons which can contain free hydrogen atoms and are essentially resistant to hydrolysis are preferred. Such compounds are generally harmless and non-flammable.

In general, the propellant gases are used in mixtures, with a high pressure propellant a low pressure propellant to have the desired final pressure in the container from which then the foam is released. The pressure is generally between 0.7 and 7.0 bar. where the Mixture usually a low pressure propellant with a pressure below 1.4 bar at room temperature and a contains other propellant which has a pressure of more than 1.4 bar or preferably more than 2.8 bar. Smaller proportions of hydrocarbon propellants can be used in mixtures described in brings in a tumble dryer provided the foam or gas being released does not are flammable.

In some cases it is useful in addition to the Propellants to use a solvent that is lipophilic and therefore with the lipophilic organic blowing agents are miscible. For example, chlorinated hydrocarbons, such as methylene chloride, mostly used in smaller quantities. Flammable solvents are generally said to be cannot be used if the products are used in the area of a heating element or an open Flame, for example in a tumble dryer, takes place.

A preferred propellant mixture for achieving a pressure in a range between 1.4 and 4.9 bar is a mixture of dichlorodifluoromethane and dichlorotetrafluoroethane. In addition, other compressed gases can also be used, such as nitrogen, carbon dioxide, nitrogen oxide, it being possible to use similar blowing agents to influence the foam properties. In general, demineralized water with a hardness below 20 ppm, measured as calcium carbonate, is used. and preferably water at less than 5 ppm. Ordinary tap water can, however, be used, with Wisser having a low hardness of, for example, less than 50 ppm, being preferred, although hard water up to 250 ppm and higher can also be used.

In addition to the main components of the mixture according to the invention, various additives can be used, such as fragrances, bactericides, fungicides, optical brighteners such as aminostilbenes, usually in small amounts, for example up to 1% 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 discharge properties to improve the mixes. Natural and synthetic gums and resins can be used for

Thickening of the emulsion to be dispensed can be used, as a result of which the dispensing speed is reduced and is more controllable, the dispensed liquid upon first contact with a The area of reduced pressure is stabilized and the foam is also stabilized after the release. As resins Can be polyvinylpyrrolidone, polyvinyl alcohol, polyacrylamide and numerous other synthetic resins, organic Gums such as guar gum, carrageenan gum, sodium alginate, caseinates and cellulose derivatives such as Sodium carboxymethyl cellulose and hydroxypropylmethyl cellulose can be used. If in that Container gelation of the mixture occurs or when dilution of the mixture is desired. can use hydrophilic solvents such as polybasic alcohols, for example propylene glycol, and glycerin other di- and polybasic alcohols can be used. In some cases, polyethylene glycols, z. U. 400 molecular weight can be used. In addition to preventing gel formation these substances support the more even foam formation and also improve the foam quality and Foam stability.

Other important additives, especially to improve the foam of nonionic foaming agents are the foam stabilizers that are also combined with anionic, cationic or amphoteric components can be. Such compounds are higher alcohols, especially higher aliphatic ones monobasic alcohols, such as straight-chain saturated alcohols with 12 to 18 carbon atoms, ζ. B. cetyl alcohol. These stabilizers are often viewed as part of the foaming agent itself as they are added to the To keep foam stable and together with the non-ionic compounds a stable foam to make it possible at all. When these compounds are omitted, the product delivered is sometimes aqueous or in spray form. In addition to cetyl alcohol, other equivalent alcohols such as stearyl alcohol, 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 used in an amount of 0.5 to 15% and amounts to 1 to 10% of the end product , for example when using an amphoteric fatty amide. If the same product is used for both the foaming agent and the conditioning agent, it is used in amounts of 1 to 30% up to 79% and preferably 40 to 79%, mostly in amounts of 40 to 60%, used. In many cases the propellant mixture is 50% of the total product. At such concentrations, especially in the range between 40 and 60%, one obtains a very stable foam, which often its shape more stood retains Some of the mixtures described with smaller propellant units do not have the desired stability, but nevertheless can be used in the invention.

The water content is usually from 20 to 50% and especially from 25 to 45%.
The amount of foam stabilizer used, which is used with the nonionic foaming agent, is usually between 0.2 and 10 and especially 0.5 and 5%. Similar amounts can be used with cationic, amphoteric and anionic foaming agents, although foam stabilizers are used.

Tors, such as cetyl alcohol, are not required for anionic surfactants, especially not for Soaps such as alkanolamine soaps. To thicken the mixture and adjust the dispensing properties, Foam strength and stability are thickening

i) medium or resins in amounts from 0.2 to 5%, in particular from 0.3 to 2.0%, as used in polyvinylpyrrolidone. If on the other hand the mix too is thick or gels during storage and is therefore difficult to dispense, a thinner

-'η agents, such as polyethylene glycol, glycerin, in general used in amounts of 1 to 10% by weight, based on the end product.

For example, if the content of triethanolamine stearate is greater than 10% of the aqueous phase of the

2ϊ mixture is, the product can gel, so that in in these cases about 5% glycerin or polyethylene glycol should be added.

The mixtures according to the invention can be produced very easily. It is enough to have all the ingredients

so except for the propellant, at room temperature too mix and, if necessary, heat to form a homogeneous mixture. The different Soaps can be made in situ. In general, the mixture does not need to exceed temperatures

to be heated over 50 °. Volatile additives such as Perfume are expediently 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 more than one propellant, one can use one Components are added one after the other or preferably as a mixture. Then it can desired valve can be attached.

The use of the product is extremely simple and is done by actuating the valve and dispensing the desired amount of conditioning agent, sometimes it is convenient to use the aerosol container before use to achieve a more even

so to shake 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 through

ss 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 fabrics 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 4 kg of dry laundry. These are amounts 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

it

means is set in the overall mixture so that one the desired amount of final product used. The quantities given relate to that from the container dispensed mixture. Since part of the propellant escapes when the agent is dispensed, the weight of the applied foam about up to 10% less than the weight of the total dispensed amount. This is especially true for a stable foam that occurs within the 5-minute period of standing Does not lose shape. It is useful if the propellant remains in the foam because it appears to 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 does not act from the outside Is exposed to forces, it is usually added in an automatic when the laundry is too damp Tumble broken open or spread over the surface of the laundry after 1 to 5 revolutions distributed in the drying drum. Such a drum usually rotates at a speed of 10 to 60 revolutions per minute, using dry air from room temperature to 200 ° C. in the In general, the laundry is circulated for 5 to 60 minutes in such a drying process. Under under these conditions, the foam is distributed preferably in connection with that to be treated Tissue moisture present on the entire surface of the textiles to be treated, makes this soft and antistatic.

The advantages of the present invention are that a practical product is proposed that satisfactorily effects the conditioning or softening of laundry without you have to go to the washing machine again. If the washed textiles after the rinsing process and The housewife only needs to spin the tumble dryer while it is still damp Put the required amount of conditioning agent as a foam on top of the laundry Close the drying drum and let the laundry dry. Here the Laundry conditioned automatically. The housewife also tells the amount of foam applied and can visually estimate how strong the conditioning is. Different from the use of spray mist, for which an optical dimension is not possible, can in the present case the housewife can rely on the recognizable product dispensed or can count the time while which she keeps the dispensing valve open. The product cannot be sprayed in the air or reappear be returned to the user.

55 shaken and then packed.

Process example

The individual mixtures A to N mentioned above were examined by, after shaking the

60 pressure container 20 g of the product to be examined applied to 4 kg of laundry which contained about 3 kg of water. Half of the test laundry consisted of Cotton and half of synthetic textiles. Non-iron textiles were among the textiles

65 made of polyester / cotton blends in a proportion of 65:35, the greater proportion of Synthetic underwear consisted of dacron and nylon. Some of the non-iron laundry was light blue in order to be oily

Better detect deposits, especially after heating or ironing. The conditioning agents were in each case within 2 minutes of removing the laundry and mostly immediately then applied as foam to the textiles in the drying drum. Immediately after the addition was made started drying with a drying gas of 70 ° C and one revolution of the Drying drum of 30 rpm. After 1 to 2 revolutions of the drum, the foam with the Textiles mixed and spread more and more on the laundry during the subsequent drying. It was dried for a total of 45 minutes.

All mixtures of the above examples were applied in an amount of 20 g per 4 kg of laundry and gave an excellent antistatic effect and a good softening of the fabric. In some Cases, namely, the compositions B, E, F, G, H and J, the effect was greatly improved when the amount used was increased to 100 g. The products C, E, K, L and M are with regard to the dimensional stability not very stable, while the other compositions are sufficiently stable and 5 minutes remain unchanged without losing shape. The foam is so stable that it can be used without destroying the Foam structure can be taken from one hand to the other hand several times.

Although the above compositions provide excellent conditioning of textiles and unc Surprisingly, no oily staining results, the compositions can correspond to be changed. For example, the propellants used can be exchanged accordingly and for dif Use other high and low pressure propellants such as B. trichloromonofluoromethane, dichloromonofluor methane, chlorodifluoromethane, 1,1,2-trifluorotrichloroethane Octafluorocyclobutane, isobutane, without the properties adversely affect the product. Furthermore can other cattonic compounds of the type described above and other amphoteric compounds use be det. It is also possible to use nonionic compounds other than those listed. Tue « various anionic compounds can replace the soaps, e.g. B. magnesium or aluminum egg fen. The proportions can also be changed, and resins, thickeners, thinners can be used tel. Foam stabilizers are added. Fernei The softening effect and the antistatic effect can be achieved by changing the proportions to be influenced.
