Description

 "Textile Care"

The invention relates to a textile care agent containing a cellulose ether with a quaternized nitrogen atom in the ether group and a washing method for washing textiles using this textile detergent in a household washing machine. Furthermore, the invention relates to the use of the textile detergent to reduce the formation of creases, improve the ironing properties and improve the elasticity.

Modern textile cleaning places high demands on the items to be cleaned. The frequent washing of clothes in an automatic washing machine and the subsequent drying in a tumble dryer is associated with a high mechanical load on the fabric. The frictional forces often damage the textile fabric, recognizable by the formation of fluff and pills. With each washing or drying cycle, but also by wearing the clothing, there is further abrasion and / or breakage of tiny fibers on the surface of the textile fabrics. The conventional textile cleaning agents are unable to prevent this damage to the fabric or are simply trying to eliminate textile damage that has already occurred.

The international patent application WO 99/16956 AI proposes the removal of fluff or pills by using cellulases. The cellulases break down microfibers that protrude from the textile fabrics and thus ensure a smooth and therefore pill-free textile surface.

Another major disadvantage of the mechanical stress on textile fabrics is the formation of wrinkled textile surfaces which are undesirable to the consumer and the formation of rough surfaces. Both the rough textile surfaces and the resulting crumpling of the fabrics lead to a considerable deterioration in the sliding properties of irons or other textile flattening devices. The effort for flattening rough and crumpled textiles is not only higher Exertion of effort, but also to be seen in a considerable additional expenditure of time. In the prior art, solutions for improving the ironing properties of washed textiles are found mainly in the field of post-treatment agents. For example, the international patent application WO 00/77134 discloses the use of oxidized polyolefins in fabric softener formulations to improve the ironing properties.

The use of celluloses, hydrogels and acrylic acid polymers as lint reduction components in textile treatment agents is known from German patent application DE 102 03 192 AI.

The US Pat. No. 3,472,840 describes quaternary nitrogen-containing cellulose ethers of the general formula (I),

((RO-) ₃ R _C ell) y (I)

in which Rc _e ιι an anhydroglucose residue (CβHioOs), the degree of polymerization y is a number from 50 to 20,000 and each of the residues R corresponds to the general formula (II),

in which a and b independently of one another 2 or 3, c 1, 2 or 3, m and p independently of one another an integer from 0 to 10, n an integer from 0 to 3, q 0 or 1, X ^" an anion, which is present in such a number according to its charge that it balances the positive charges of the quaternary nitrogen atoms, and R 'is hydrogen, a carboxylic acid group or a sodium, potassium or ammonium carboxylate group with the proviso that R' is hydrogen if q 0. The compounds of the formula I can, as described there, be obtained by reacting conventional or previously specially prepared nonionic cellulose ethers with quaternary halohydrins or quaternary epoxides. Surprisingly, it has now been found that the use of such quaternary nitrogen-containing cellulose ethers in the washing process leads to a significant improvement in the fiber and textile properties.

In a first embodiment, the present invention therefore relates to a textile care agent containing cellulose ethers of the general formula (I) containing quaternary nitrogen,

((RO-) ₃ R _Ce ιι) _y (I)

in which Rc _e ιι an anhydroglucose residue (C ₆ HιoO ₅ ), the degree of polymerization y is a number from 50 to 20,000 and each of the residues R corresponds to the general formula (II),

- (C _a H _2a -O) _m - (CH ₂ -CH-O) _n - (C _b H _2b -O) _p - (C _c H _2c ) _q -R '(II) CH ₂ -N ⁺ RιR ₂ R ₃ X ^"

in which a and b independently of one another 2 or 3, c 1, 2 or 3, m and p independently of one another an integer from 0 to 10, n an integer from 0 to 3, q 0 or 1, X ^" an anion, which is present in such a number according to its charge that it balances the positive charges of the quaternary nitrogen atoms, and R 'is hydrogen, a carboxylic acid group or a sodium, potassium or ammonium carboxylate group with the proviso that R' is hydrogen if q Is 0.

In the context of this invention, textile care agents are understood to mean both detergents and cleaning agents and pretreatment agents and agents for conditioning textile fabrics, such as mild detergents and post-treatment agents, such as fabric softeners. Conditioning is to be understood as the finishing treatment of fabrics, fabrics, yarns and fabrics. The conditioning is intended to impart positive properties to the textiles, such as an improved soft feel, increased gloss and color brilliance, refreshing the scent and reducing the creasing behavior and the static charge. When using agents according to the invention, in particular the crumpling of textiles by the washing and / or drying process is prevented, the ironing properties of the textile are improved and the “wear and tear” of the textiles during washing is considerably reduced.

The textile care agents according to the invention can be present in solid form, for example as powder, granulate, extrudate, pressed and / or melted shaped body as as a tablet, or in liquid form, for example as a dispersion, suspension, emulsion, solution, microemulsion, gel or paste. In a preferred embodiment of the invention, they are liquid. The agents according to the invention preferably contain 0.1% by weight to 5% by weight, in particular 0.1% by weight to 1% by weight, of cellulose ether of the general formula (I) containing quaternary nitrogen. In the compounds of formula (I), y is preferably in the range from 200 to 5,000. For each anro-glucose unit Rceii, n is preferably 0.01 to 1, in particular 0.1 to 0.5, that is to say averaged over the entire cellulose ether in particular, every tenth to every second anhydroglucose unit is substituted with a group bearing a quaternary nitrogen atom. The sum of m, n, p and q per anydroglucose unit Rceii is preferably 0.01 to 4, in particular 0.1 to 2 and particularly preferably 0.8 to 2 as the mean value.

In addition to the groups bearing the quaternary nitrogen atom, the cellulose ethers to be used according to the invention preferably contain methyl, ethyl, propyl, hydroxyethyl and / or hydroxypropyl groups. These groups form part of the radicals R and / or as part of the group - (C _b H _2b -O) _p - (C _c H _2c ) _q -R 'are part of the group bearing the quaternary nitrogen atom.

The average molecular weight Mw of the cellulose ethers to be used according to the invention is preferably above 5000, particularly preferably above 10000, in particular above 15000, advantageously between 30,000 and 250,000, most preferably between 50,000 and 100,000 g / mol. The molecular weight can be determined by gel permeation chromatography against standardized polyacrylic acid standards. In a preferred embodiment of the present invention, the textile care agents contain complexing agents in addition to the cellulose ether with quaternary nitrogen atom. It has surprisingly been found that, in particular, organic, advantageously water-soluble, complexing agents can be incorporated particularly well into the textile care agents according to the invention and, in particular together with the cellulose ethers to be used according to the invention, gives the textile care agent, including in particular the liquid preparations, increased stability. The complexing agents improve the stability of the agents and protect, for example, against the decomposition of certain ingredients of active detergent formulations catalyzed by heavy metals. Together with the cellulose ethers to be used according to the invention, they contribute to the inhibition of incrustations. The group of complexing agents includes, for example, the salts, in particular the alkali metal salts of nitrilotriacetic acid (NTA) and their derivatives, and alkali metal salts of anionic polyelectrolytes such as polymaleates and polysulfonates. Citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids and their derivatives and mixtures of these are also suitable. Preferred compounds include, in particular, organophosphonates such as, for example, 1-hydroxyethane-1, 1-diphosphonic acid (HEDP), aminotri (methylenephosphonic acid) (ATMP), diethylenetriamine-penta (methylenephosphonic acid) (DTPMP or DETPMP) and 2-phosphonobutane-1, 2,4-tricarboxylic acid (PBS-AM), which are mostly used in the form of their ammonium or alkali metal salts. Citric acid and / or its alkali metal salts, for example sodium citrate and / or potassium citrate, are particularly preferred in the context of the present invention. In a preferred embodiment, the textile care agents contain complexing agents in an amount of up to 20% by weight, preferably from 0.01 to 15% by weight, particularly preferably from 0.1 to 10 and in particular from 0.3 to 5.0% by weight. -%, advantageously from 1.5 to 3% by weight, in each case based on the total agent.

In a preferred embodiment, the textile care agents according to the invention additionally contain nonionic surfactants. The use of nonionic surfactants not only increases the washing performance of the agents according to the invention, but also increases the Dispersion and homogeneous distribution of the cellulose ether to be used according to the invention are supported.

Preferred nonionic surfactants are alkoxylated, advantageously ethoxylated and / or propoxylated, in particular primary alcohols with preferably 8 to 18 carbon atoms and an average of 1 to 12 mol ethylene oxide (EO) and / or 1 to 10 mol propylene oxide (PO) per mol alcohol, used. C ₈ -C ₆ alcohol alkoxylates are particularly preferred, advantageously ethoxylated and / or propoxylated Cιo-C. ₅ - alcohol alkoxylates, in particular C ₂ -C ₄ alcohol alkoxylates, with a degree of ethoxylation between 2 and 10, preferably between 3 and 8, and / or a degree of propoxylation between 1 and 6, preferably between 1.5 and 5. The alcohol residue can preferably be linear or particularly preferably be methyl-branched in the 2-position or contain linear and methyl-branched radicals in the mixture, as are usually present in oxo alcohol radicals. However, alcohol ethoxylates with linear residues of alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, tallow or oleyl alcohol, and an average of 2 to 8 EO per mole of alcohol are particularly preferred. ₁₄ - - The preferred ethoxylated alcohols include, for example, ₁₂ C, alcohols containing 3 EO or 4 EO, C ₉ -π alcohol containing 7 EO, C13-15- alcohols containing 3 EO, 5 EO, 7 EO or 8 EO, C ₁₂ -ι ₈ - alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of Cι ₂ -ι - alcohol with 3 EO and C12-18- alcohol with 5 EO. The degrees of ethoxylation and propoxylation given represent statistical averages, which can be an integer or a fraction for a specific product. Preferred alcohol ethoxylates and propoxylates have a narrow homolog distribution (narrow range ethoxylates / propoxylates, NRE / NRP). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples include tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO.

Also suitable are alkoxylated amines, advantageously ethoxylated and / or propoxylated, in particular primary and secondary amines with preferably 1 to 18 carbon atoms per alkyl chain and an average of 1 to 12 mol ethylene oxide (EO) and / or 1 to 10 mol propylene oxide (PO) per Mole of amine. The end-capped alkoxylated fatty amines and fatty alcohols have proven to be particularly advantageous, particularly for use in non-aqueous formulations according to the invention. The terminal hydroxyl groups of the fatty alcohol alkoxylates and fatty amine alkoxylates are etherified in the end-capped fatty alcohol alkoxylates and fatty amine alkoxylates by C 1 -C ₂₀ alkyl groups, preferably methyl or ethyl groups.

In addition, alkyl glycosides of the general formula RO (G) _x> can also be used as further nonionic surfactants, for example as compounds, especially with anionic surfactants, in which R is a primary straight-chain or methyl-branched, in particular in the 2-position methyl-branched aliphatic radical having 8 to 22 , preferably means 12 to 18 carbon atoms and G is the symbol which stands for a glycose unit with 5 or 6 carbon atoms, preferably for glucose. The degree of oligomerization x, which indicates the distribution of monoglycosides and oligoglycosides, is any number between 1 and 10; x is preferably 1.2 to 1.4.

Another class of preferably used nonionic surfactants, which are used either as the sole nonionic surfactant or in combination with other nonionic surfactants, are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters, preferably with 1 to 4 carbon atoms in the alkyl chain, in particular fatty acid methyl esters, such as them are described, for example, in Japanese patent application JP 58/217598 or which are preferably produced by the process described in international patent application WO-A-90/13533.

So-called gemini surfactants can be considered as further surfactants. These are generally understood to mean those compounds which have two hydrophilic groups and two hydrophobic groups per molecule. These groups are usually separated from one another by a so-called "spacer". This spacer is usually a carbon chain, which should be long enough that the hydrophilic groups have a sufficient distance so that they can act independently of one another. Such surfactants are generally characterized by an unusually low critical micelle concentration and the ability to greatly reduce the surface tension of the water. In exceptional cases, however, the term gemini surfactants means not only dimeric but also trimeric surfactants.

Suitable gemini surfactants are, for example, sulfated hydroxy mixed ethers according to German patent application DE-A-43 21 022 or dimer alcohol bis and trimeral alcohol tris sulfates and ether sulfates according to international patent application WO-A-96/23768. End group-capped dimeric and trimeric mixed ethers according to German patent application DE-A-195 13 391 are distinguished in particular by their bi- and multifunctionality. The end-capped surfactants mentioned have good wetting properties and are low-foaming, so that they are particularly suitable for use in machine washing or cleaning processes.

Gemini polyhydroxy fatty acid amides or poly poly hydroxy fatty acid amides can also be used. as described in international patent applications WO-A-95/19953, WO-A-95/19954 and WO-A-95/19955.

Other suitable surfactants are polyhydroxy fatty acid amides of the following formula,

R ³ R ⁴ -CO-N- [Z]

in the R ⁴ CO for an aliphatic acyl radical having 6 to 22 carbon atoms, R ³ for hydrogen, an alkyl or hydroxyalkyl radical with 1 to 4 carbon atoms and [Z] for a linear or branched polyhydroxyalkyl radical with 3 to 10 carbon atoms and 3 to 10 hydroxyl groups stands. The polyhydroxy fatty acid amides are known substances which can usually be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.

The group of polyhydroxy fatty acid amides also includes compounds of the following formula R ⁶ -OR ⁷ . I

R ⁵ -CO-N- [Z]

in which R ^{5 represents} a linear or branched alkyl or alkenyl radical having 7 to 12 carbon atoms, R ^{6 represents} a linear, branched or cyclic alkyl radical or an aryl radical having 2 to 8 carbon atoms and R ^{7 represents} a linear, branched or cyclic alkyl radical or Aryl radical or an oxy-alkyl radical having 1 to 8 carbon atoms, C - alkyl or phenyl radicals being preferred and [Z] being a linear polyhydroxyalkyl radical whose alkyl chain is substituted by at least two hydroxyl groups, or alkoxylated, preferably ethoxylated or propoxylated derivatives thereof residue. [Z] is preferably obtained by reductive amination of a reduced sugar, for example glucose, fructose, maltose, lactose, galactose, mannose or xylose. The N-alkoxy- or N-aryloxy-substituted compounds can then, for example according to the teaching of international patent application WO-A-95/07331, be converted into the desired polyhydroxy fatty acid amides by reaction with fatty acid methyl esters in the presence of an alkoxide as catalyst.

It has proven to be advantageous for the textile care products according to the invention if nonionic surfactants selected from the group of alkoxylated fatty alcohols and / or alkyl glycosides, in particular mixtures of alkoxylated fatty alcohols and alkyl glycosides, are used.

In a preferred embodiment, the textile care agents according to the invention contain nonionic surfactants in amounts of up to 35% by weight, preferably from 5 to 25% by weight, particularly preferably from 10 to 20% by weight, in each case based on the total agent ,

Furthermore, the textile care agents according to the invention can also contain anionic surfactants in addition to or instead of the nonionic surfactants. The use of anionic surfactants significantly increases the soil release behavior of the agents according to the invention during the washing process, without the effect of cellulose ethers to be used according to the invention - despite their cationic charge - as an eluent reduction component and anti-crease component.

Anionic surfactants used are, for example, those of the sulfonate and sulfate type. As surfactants of the sulfonate type, preference is given to C ₃ alkylbenzenesulfonates, olefin sulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates such as are obtained, for example, from C ₈ monoolefins having an end or internal double bond by sulfonation Gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products. Also suitable are alkanesulfonates obtained from Cπ-is-alkanes, for example by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization. The esters of α-sulfofatty acids (ester sulfonates), for example the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids, are also suitable.

Other suitable anionic surfactants are sulfonated fatty acid glycerol esters. Fatty acid glycerol esters are to be understood as the mono-, di- and triesters and their mixtures as obtained in the production by esterification of a monoglycerin with 1 to 3 moles of fatty acid or in the transesterification of triglycerides with 0.3 to 2 moles of glycerol become. Preferred sulfated fatty acid glycerol esters are the sulfonation products of saturated fatty acids having 6 to 22 carbon atoms, for example caproic acid, caprylic acid, capric acid, myristic acid, lauric acid, palmitic acid, stearic acid or behenic acid.

As alk (en) yl sulfates, the alkali and in particular the sodium salts of the sulfuric acid semiesters of the C ₂ -C ₈ fatty alcohols, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C ₀ -C ₂₀ oxo alcohols and those half-esters of secondary alcohols of this chain length are preferred. Also preferred are alk (en) yl sulfates of the chain length mentioned, which contain a synthetic, petrochemical-based straight-chain alkyl radical which have a degradation behavior similar to that of the adequate compounds based on oleochemical raw materials. The C12-C] ₆ alkyl sulfates and Ci ₂ -C _{] 5} alkyl sulfates and C _] -C ₅ alkyl sulfates are preferred for washing technology reasons. Also 2,3-alkyl sulfates, which are prepared for example according to patents US 3,234,258 or US 5,075,041 and can be obtained as commercial products from Shell Oil Company under the name DAN ^®, are suitable anionic surfactants.

The sulfuric acid monoesters of the straight-chain or branched C ethoxylated with 1 to 6 mol of ethylene oxide. ₂₁ alcohols, such as 2-methyl-branched C.n. alcohols with an average of 3.5 moles of ethylene oxide (EO) or -C ₂ -ι ₈ fatty alcohols with 1 to 4 EO, which are referred to as fatty alcohol ether sulfates, are suitable and in Anionic surfactants particularly preferred in the context of this invention.

Other suitable anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters and which are monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and in particular ethoxylated fatty alcohols. Preferred sulfosuccinates contain C _{8-0 8} fatty alcohol residues or mixtures thereof. Particularly preferred sulfosuccinates contain a fatty alcohol residue which is derived from ethoxylated fatty alcohols, which are nonionic surfactants in themselves. Again, sulfosuccinates, the fatty alcohol residues of which are derived from ethoxylated fatty alcohols with a narrow homolog distribution, are particularly preferred. It is also possible to use alk (en) ylsuccinic acid with preferably 8 to 18 carbon atoms in the alk (en) yl chain or salts thereof.

Soaps are particularly suitable as further anionic surfactants. Suitable are, for example, the saturated fatty acid soaps, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid, and in particular from natural fatty acids, e.g. Coconut, palm kernel or tallow fatty acids, derived soap mixtures.

The anionic surfactants, including the soaps, can be in the form of their sodium, potassium or ammonium salts and also as soluble salts of organic bases, such as mono-, di- or triethanolamine. The anionic surfactants are preferably in the form of their sodium or potassium salts, in particular in the form of the sodium salts. For the However, non-aqueous liquid detergents according to the invention, the ammonium salts, in particular the salts of organic bases, such as isopropylamine, are preferred.

Another class of anionic surfactants is the class of ether carboxylic acids which can be obtained by reacting fatty alcohol ethoxylates with sodium chloroacetate in the presence of basic catalysts. They have the general formula: R ¹⁰ O- (CH ₂ -CH ₂ -O) _p -CH ₂ - COOH with R ¹⁰ = Cι-Cι ₈ and p = 0.1 to 20. Ether carboxylic acids are insensitive to water hardness and have excellent surfactant properties , Production and application are, for example, in soaps, oils, fats, waxes 101, 37 (1975); 115, 235 (1989) and Tenside Deterg. 25, 308 (1988).

In a preferred embodiment, the textile cleaning agents according to the invention contain anionic surfactants, preferably selected from the group consisting of fatty alcohol sulfates and / or fatty alcohol ether sulfates and / or alkylbenzenesulfonates and / or soaps.

Depending on the intended use of the textile care products according to the invention, the content of anionic surfactants can vary considerably. If the textile care agents are present as mild detergents or aftertreatment agents, for example as fabric softeners, the amounts are normally below 10% by weight, preferably below 5% by weight and in particular below 1% by weight, in each case based on the total agent ,

If the textile care products are in the form of solid or liquid heavy-duty detergents, for example non-aqueous liquid detergents, anionic surfactants can be used in amounts of up to 65% by weight, preferably in amounts of up to 50% by weight, particularly preferably in amounts of 5 to 35% by weight. -%, each based on the total agent, may be included.

In a preferred embodiment, the textile care agents according to the invention can also additionally contain enzymes.

Enzymes support the washing processes in a variety of ways, in particular in the removal of badly bleachable impurities, such as protein soiling. The incorporation of enzymes in detergent formulations, especially in However, liquid textile care products often cause problems because they can cause incompatibilities with other detergent components, which in turn can cause the enzymes to lose their activity. It has surprisingly been found that the stability of the enzymes in wash liquor or textile care agent formulation, in particular in liquid textile care agent formulations, can be improved by using the copolymers to be used according to the invention.

Particularly suitable enzymes are those from the classes of hydrolases such as proteases, esterases, lipases or lipolytically active enzymes, amylases, cellulases or other glycosyl hydrolases and mixtures of the enzymes mentioned. All of these hydrolases help to remove stains such as protein, fat or starchy stains and graying in the laundry. Cellulases and other glycosyl hydrolases can also help to retain color and increase the softness of the textile by removing pilling and microfibrils. Oxireductases can also be used to bleach or inhibit the transfer of color. Enzymatic active ingredients obtained from bacterial strains or fungi such as Bacillus subtilis, Bacillus licheniformis, Streptomyceus griseus and Humicola insolens are particularly suitable. Proteases of the subtilisin type and in particular proteases which are obtained from Bacillus lentus are preferably used. Enzyme mixtures, for example from protease and amylase or protease and lipase or lipolytically active enzymes or protease and cellulase or from cellulase and lipase or lipolytically active enzymes or from protease, amylase and lipase or lipolytically active enzymes or protease, lipase or lipolytically active enzymes and cellulase, but especially protease and / or lipase-containing mixtures or mixtures with lipolytically active enzymes of particular interest. Known cutinases are examples of such lipolytically active enzymes. Peroxidases or oxidases have also proven to be suitable in some cases. Suitable amylases include in particular α-amylases, iso-amylases, pullulanases and pectinases. Cellobiohydrolases, endoglucanases and β-glucosidases, which are also called cellobiases, or mixtures thereof, are preferably used as cellulases. Because different types of cellulase are characterized by their CMCase and Avicelase activities differ, the desired activities can be set by targeted mixtures of the cellulases.

The enzymes can be adsorbed or coated on carriers in order to protect them against premature decomposition.

In a preferred embodiment, the textile care agents according to the invention contain enzymes, preferably selected from the group of proteases and / or amylases and / or cellulases.

If the textile care agents according to the invention are present as mild detergents or aftertreatment agents, for example as fabric softeners, in a preferred embodiment they can contain cellulase, preferably in an amount of 0.005 to 2% by weight, particularly preferably 0.01 to 1% by weight, in particular from 0.02 to 0.5% by weight. in each case based on the total composition.

In a preferred embodiment, the textile care products according to the invention are in liquid form and advantageously have a viscosity of 50 to 5000 mPas, particularly preferably 50 to 3000 mPas and in particular 500 to 1500 mPas (measured at 20 ° C. with a rotary viscometer (Brookfield RV, spindle 2) at 20 rpm (rpm: revolutions per minute)).

In a preferred embodiment, preferred liquid textile care agents contain one or more non-aqueous, water-miscible solvents.

Solvents which can be used in the water-containing agents according to the invention come, for example, from the group of mono- or polyhydric alcohols, alkanolamines or glycol ethers, provided that they are miscible with water in the concentration range desired for the use. The solvents are preferably selected from ethanol, n- or i-propanol, butanols, glycol, propane or butanediol, glycerol.

Butoxytriglycol, l-butoxyethoxy-2-propanol, 3-methyl-3-methoxybutanol, propylene glycol t-butyl ether and mixtures of these solvents.

Some glycol ethers are available under the trade names Arcosolv ^® (Arco Chemical Co.) or Cellosolve ^® , Carbitol ^® or Propasol ^® (Union Carbide Corp.); these also include, for example, ButylCarbitol ^® , HexylCarbitol ^® , MethylCarbitol ^® , and Carbitol ^® itself, (2- (2-ethoxy) ethoxy) ethanol. The choice of the glycol ether can be easily made by those skilled in the art based on its volatility, water solubility, weight percent of the total, and the like. Pyrrolidone solvents such as N-alkyl pyrrolidones, for example N-methyl-2-pyrrolidone or NC ₈ -Ci ₂ alkylpyrrolidone, or 2-pyrrolidone can also be used. Alcohols can furthermore preferably be used. They include liquid polyethylene glycols with a low molecular weight, for example polyethylene glycols with a molecular weight of 200, 300, 400 or 600. Other suitable other alcohols are, for example, lower alcohols such as ethanol, propanol, isopropanol and n-butanol, C ₂ -C ₄ - Polyols, such as diols or triols, for example ethylene glycol, propylene glycol, glycerol or mixtures thereof.

If they are in liquid form, the textile care agents according to the invention contain up to 95% by weight, particularly preferably 20 to 90% by weight and in particular 50 to 80% by weight of one or more solvents, preferably water-soluble solvents, in a preferred embodiment and especially water.

In a preferred embodiment of the invention, the textile care agents additionally contain plasticizer components, preferably cationic surfactants. The use of additional plasticizer components has proven to be extremely advantageous in particular when the textile care agents according to the invention are present as mild detergents or textile aftertreatment agents, for example as fabric softeners. Especially when washing delicate textiles, such as silk, wool or linen, which are washed and ironed at low temperatures, the use of softeners proven components. In addition to the cellulose ethers to be used according to the invention, the plasticizer components also make it easier to iron the textiles and reduce the static charge on the textile materials.

Examples of fabric softening components are quaternary ammonium compounds, cationic polymers and emulsifiers, such as are used in hair care products and also in textile finishing agents.

Suitable examples are quaternary ammonium compounds of the formulas (III) and (IV),

A preferred polymeric polysaccharide thickener is xanthan, a microbial anionic heteropolysaccharide that is produced by Xanthomonas campestris and some other species under aerobic conditions and has a molecular weight of 2 to 15 million g / mol. Xanthan is formed from a chain with ß-1,4-bound glucose (cellulose) with side chains. The structure of the subgroups consists of glucose, mannose, glucuronic acid, acetate and pyruvate, whereby the number of pyruvate units determines the viscosity of the xanthan.

Xanthans and modified xanthans can be used with particular advantage because of their very high stability.

The textile care agents according to the invention can additionally contain further detergent additives, for example from the group of builders, bleaching agents, bleach activators, electrolytes, pH regulators, fragrances, perfume carriers, fluorescent agents, dyes, foam inhibitors, graying inhibitors, antimicrobial agents, germicides, fungicides, antioxidants, antioxidants, antioxidants, antioxidants Ironing aids, UV absorbers, optical brighteners, anti-redeposition agents, viscosity regulators, enema preventers, corrosion inhibitors, preservatives, phobing and impregnating agents.

The agents according to the invention can contain builders. All builders commonly used in detergents and cleaning agents can be incorporated into the agents according to the invention, in particular zeolites, silicates, carbonates, organic cobuilders and — insofar as there are no ecological prejudices against their use — also the phosphates.

Suitable crystalline, layered sodium silicates have the general formula NaMSi _x θ ₂ χ ₊ ι • y H ₂ O. where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20 and preferred values for x are 2, 3 or 4. Such crystalline layered silicates are described, for example, in European patent application EP-A-0 164 514. Preferred crystalline layered silicates of the formula given are those in which M represents sodium and x assumes the values 2 or 3. In particular, both β- and δ-sodium disilicate Na ₂ Si ₂ θ ₅ • y H ₂ O are preferred, whereby β-sodium disilicate can be obtained, for example, by the method described in international patent application WO-A-91/08171.

Amorphous sodium silicates with a module Na ₂ O: Si0 ₂ of 1: 2 to 1: 3.3, preferably from 1: 2 to 1: 2.8 and in particular from 1: 2 to 1: 2.6, can also be used are delayed in dissolving and have secondary washing properties. The dissolution delay compared to conventional amorphous sodium silicates can be done in different ways, for example, caused by surface treatment, compounding, compacting, sealing or overdrying. In the context of this invention, the term “amorphous” is also understood to mean “X-ray amorphous”. This means that the silicates in X-ray diffraction experiments do not provide sharp X-ray reflections, as are typical for crystalline substances, but at most one or more maxima of the scattered X-rays, which have a width of several degree units of the diffraction angle. However, it can very well lead to particularly good builder properties if the silicate particles provide washed-out or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline areas of size 10 to a few hundred .mu.m, values up to max. 50 nm and in particular up to max. 20 µm are preferred. Such so-called X-ray amorphous silicates, which likewise have a delay in dissolution compared to conventional water glasses, are described, for example, in German patent application DE-A-44 00 024. Compacted / compacted amorphous silicates, compounded amorphous silicates and over-dried X-ray amorphous silicates are particularly preferred.

The finely crystalline, synthetic and bound water-containing zeolite is preferably zeolite A and / or P. As zeolite P, zeolite ^MAP® (commercial product from Crosfield) is particularly preferred. However, zeolite X and mixtures of A, X and / or P are also suitable. Commercially available and can preferably be used in the context of the present invention, for example a co-crystallizate of zeolite X and zeolite A (about 80% by weight zeolite X) ), which is sold by CONDEA Augusta SpA under the brand name VEGOBOND AX ^® and which has the formula nNa ₂ O • (ln) K ₂ O • Al ₂ O ₃ • (2 - 2.5) SiO ₂ • (3, 5 - 5.5) H ₂ O

can be described. Suitable zeolites have an average particle size of less than 10 μm (volume distribution; measurement method: Coulter Counter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight, of bound water. The zeolites can also be used as over-dried zeolites with lower water contents and are then suitable due to their hygroscopicity for removing unwanted traces of free water. Of course, it is also possible to use the generally known phosphates as builder substances, provided that such use should not be avoided for ecological reasons. The sodium salts of orthophosphates, pyrophosphates and in particular tripolyphosphates are particularly suitable.

Polymeric polycarboxylates are also suitable as builders, for example the alkali metal salts of polyacrylic acid or polymethacrylic acid, for example those with a relative molar mass of 500 to 70,000 g / ml.

The molar masses given here for polymeric polycarboxylates are weight-average molar masses M _{w of} the respective acid form, which can in principle be determined by means of gel permeation chromatography (GPC), a UV detector being used. The measurement is carried out against an external standard, for example against a polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship with the polymers investigated. This information often deviates significantly from the molecular weight information, for which polystyrene sulfonic acids are used as standard. The molar masses measured against polystyrene sulfonic acids are generally significantly higher. Suitable polymers are, in particular, polyacrylates, which preferably have a molecular weight of 2,000 to 20,000 g / mol. Because of their superior solubility, the short-chain polyacrylates with molecular weights of 2,000 to 10,000 g / mol, and particularly preferably 3,000 to 5,000 g / mol, can in turn be preferred from this group.

Suitable polymers can also comprise substances which consist partly or completely of units of vinyl alcohol or its derivatives.

Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their relative molecular weight, based on free acids, is generally 2,000 to 70,000 g / mol, preferably 20,000 to 50,000 g / mol and in particular 30,000 to 40,000 g / mol. The (co) polymeric polycarboxylates can either be aqueous

Solution or preferably used as a powder. i

To improve the solubility in water, the polymers can also contain AUylsulfonic acids, such as, for example, AUyloxybenzenesulfonic acid and methallylsulfonic acid, as a monomer, as disclosed in patent EP-B-0727448.

Further preferred copolymers are those which are described in German patent applications DE-A-43 03 320 or DE-A-44 17 734 and which preferably contain acrolein and acrylic acid / acrylic acid salts or acrolein and vinyl acetate as monomers.

Particularly preferred are polyaspartic acids or their salts and derivatives, of which it is disclosed in German patent application DE-A-195 40 086 that, in addition to cobuilder properties, they also have a bleach-stabilizing effect. Polyvinylpyrrolidones, polyamine derivatives such as quaternized and / or ethoxylated hexamethylene diamines are also suitable.

Other suitable builder substances are polyacetals, which can be obtained by reacting dialdehydes with polyolcarboxylic acids which have 5 to 7 carbon atoms and at least 3 hydroxyl groups, for example as described in European patent application EP-A-0 280 223. Preferred polyacetals are obtained from dialdehydes such as glyoxal, glutaraldehyde, terephthalaldehyde and mixtures thereof and from polyol carboxylic acids such as gluconic acid and / or glucoheptonic acid.

Also suitable as organic builder substances are dextrins, for example oligomers or polymers of carbohydrates, which can be obtained by partial hydrolysis of starches. The hydrolysis can be carried out by customary, for example acid or enzyme-catalyzed, processes. They are preferably hydrolysis products with average molecular weights in the range from 400 to 500,000 g / mol. Here is a polysaccharide with a dextrose equivalent (DE) in the range of 0.5 to 40, in particular from 2 to 30, is preferred, DE being a customary measure of the reducing effect of a polysaccharide compared to dextrose, which has a DE of 100. Both maltodextrins with a DE between 3 and 20 and dry glucose syrups with a DE between 20 and 37 as well as so-called yellow dextrins and white dextrins with higher molar masses in the range from 2,000 to 30,000 g / mol can be used. The oxidized derivatives of such dextrins are their reaction products with oxidizing agents which are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. Such oxidized dextrins and processes for their preparation are known, for example, from European patent applications EP-A-0 232 202, EP-A-0 427 349, EP-A-0 472 042 and EP-A-0 542 496 as well as international patent applications WO- A-92/18542, WO-A-93/08251, WO-A-93/16110, WO-A-94/28030, WO-A-95/07303, WO-A-95/12619 and WO-A- 95/20608 known. An oxidized oligosaccharide according to German patent application DE-A-196 00 018 is also suitable. A product oxidized at C _{6 of} the saccharide ring can be particularly advantageous.

Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate, are further suitable cobuilders. Ethylene diamine N, N'-disuccinate (EDDS), the synthesis of which is described, for example, in US Pat. No. 3,158,615, is preferably used in the form of its sodium or magnesium salts. Also preferred in this context are glycerol disuccinates and glycerol trisuccinates, as described, for example, in US Pat. Nos. 4,524,009, 4,639,325, in European patent application EP-A-0 150 930 and in Japanese patent application JP-A-93/339 896 become. Suitable amounts used in formulations containing zeolite and / or silicate are about 3 to 15% by weight.

Further usable organic cobuilders are, for example, acetylated hydroxycarboxylic acids or their salts, which may optionally also be in lactone form and which contain at least 4 carbon atoms and at least one hydroxyl group and at most two acid groups. Such cobuilders are described, for example, in international patent application WO 95/20029. The agents according to the invention can optionally contain builders in amounts of 1 to 60% by weight, preferably 20 to 50% by weight.

The agents according to the invention can contain bleaching agents.

Among the compounds which serve as bleaching agents and supply H ₂ O ₂ in water, sodium percarbonate, sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance. Further bleaching agents that can be used are, for example, peroxopyrophosphates, citrate perhydrates and H ₂ O ₂ -producing peracidic salts or peracids, such as persulfates or persulfuric acid. The urea peroxohydrate percarbamide can also be used, which can be described by the formula H ₂ N-CO-NH ₂ ^• H ₂ O ₂ . In particular when using the agents for cleaning hard surfaces, for example in automatic dishwashing, they can, if desired, also contain bleaching agents from the group of organic bleaching agents, although their use is in principle also possible for agents for textile washing. Typical organic bleaching agents are the diacyl peroxides, such as dibenzoyl peroxide. Other typical organic bleaching agents are peroxy acids, examples of which include alkyl peroxy acids and aryl peroxy acids. Preferred representatives are peroxybenzoic acid and its ring-substituted derivatives, such as alkylperoxybenzoic acids, but also peroxy-α-naphthoic acid and magnesium monoperphthalate. the aliphatic or substituted aliphatic peroxyacids, such as peroxylauric acid, peroxystearic acid, ε-phthalimidoperoxycaproic acid (phthalimidoperoxyhexanoic acid, PAP), o-carboxybenzamidoperoxycaproic acid, N-nonenylamidoperadipate acid and N-nonenylamidopersiphenic-12 Diperoxycarboxylic acid, 1,9-diperoxyazelaic acid, diperoxysebacic acid, diperoxybrassylic acid, the diperoxyphthalic acids, 2-decyldiperoxybutane-l, 4-diacid, N, N-terephthaloyl-di (6-aminopercaproic acid) can be used.

In order to bring the pH of the agents according to the invention into the desired range, the use of pH adjusting agents can be indicated. All known acids or bases can be used here, provided that their use is not prohibited for application-related or ecological reasons or for reasons of consumer protection. The amount of these adjusting agents usually does not exceed 2% by weight of the total formulation.

The agents according to the invention can contain colorants and fragrances.

Dyes and fragrances are added to the agents according to the invention in order to improve the aesthetic impression of the products and, in addition to the washing or cleaning performance, to provide the consumer with a visually and sensorially "typical and unmistakable" product. Individual fragrance compounds, for example the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as perfume oils or fragrances.

The agents according to the invention can contain UV absorbers, which absorb onto the treated textiles and improve the lightfastness of the fibers and / or the lightfastness of other formulation components. UV absorbers are understood to mean organic substances (light protection filters) which are able to absorb ultraviolet rays and release the absorbed energy in the form of longer-wave radiation, for example heat. Compounds which have these desired properties are, for example, the compounds and derivatives of benzophenone which are active by radiationless deactivation and have substituents in the 2- and / or 4- position.

The UV-A and UV-B filters can of course also be used in mixtures. In addition to the soluble substances mentioned, insoluble light-protection pigments, namely finely dispersed, preferably nanoized metal oxides or salts, are also suitable for this purpose. Examples of suitable metal oxides are, in particular, zinc oxide and titanium dioxide and, in addition, oxides of iron, zirconium, silicon, manganese, aluminum and cerium and mixtures thereof. Silicates (talc), barium sulfate or zinc stearate can be used as salts. The oxides and salts are already used in the form of the pigments for skin-care and skin-protecting emulsions and decorative cosmetics. The particles should have an average diameter of less than 100 nm, preferably between 5 and 50 nm and in particular between 15 and 30 nm. They can have a spherical shape, but it is also possible to use particles which have an ellipsoidal shape or a shape which differs in some other way from the spherical shape. The pigments can also be surface-treated, ie hydrophilized or hydrophobicized. Typical examples are coated titanium dioxides, such as titanium dioxide T 805 (Degussa) or Eusolex® T2000 (Merck). Silicones, and in particular trialkoxyoctylsilanes or simethicones, are particularly suitable as hydrophobic coating agents. Micronized zinc oxide is preferably used. Further suitable UV light protection filters can be found in the overview by P. Finkel in SÖFW-Journal 122, 543 (1996). UV absorbers are usually used in amounts of from 0.01% by weight to 5% by weight, preferably from 0.03% by weight to 1% by weight.

To support the corresponding action of the cellulose ether to be used according to the invention, the agents according to the invention can contain additional anti-crease agents, since textile fabrics, in particular made from rayon, wool, cotton and their mixtures, can tend to crease, because the individual fibers prevent bending, kinking, pressing and squeezing across Grain direction are sensitive. These include, for example, synthetic products based on fatty acids, fatty acid esters, fatty acid amides, alkylol esters, alkylolamides or fatty alcohols, which are mostly reacted with ethylene oxide, or products based on lecithin or modified phosphoric acid esters.

The agents according to the invention can contain graying inhibitors. These have the task of keeping the dirt detached from the fiber suspended in the liquor and thus preventing the dirt from being re-absorbed. Water-soluble colloids of mostly organic nature are suitable for this, for example glue, gelatin, salts of ether sulfonic acids of starch or cellulose or salts of acidic sulfuric acid esters of cellulose or starch. Water-soluble polyamides containing acidic groups are also suitable for this purpose. Soluble starch preparations and starch products other than those mentioned above can also be used, for example degraded starch, aldehyde starches, etc. Polyvinylpyrrolidone can also be used. However, preference is given to anionic or nonionic cellulose ethers such as carboxymethyl cellulose (sodium salt), methyl cellulose, hydroxyalkyl cellulose and Mixed ethers such as methylhydroxyethylcellulose, methylhydroxypropylcellulose and / or methylcarboxymethylcellulose.

In a particularly preferred embodiment, the textile care agents according to the invention, preferably liquid detergents, are present as a portion in a completely or partially water-soluble envelope. The portioning makes it easier for the consumer to measure it.

The textile care products can be packaged in foil bags, for example. Pouch packaging made from water-soluble film makes it unnecessary for the consumer to tear open the packaging. In this way, it is convenient to dose a single portion measured for one wash cycle by inserting the bag directly into the washing machine or by throwing the bag into a certain amount of water, for example in a bucket, a bowl or in the hand wash basin or sink. possible. The foil pouch surrounding the washing portion dissolves without residue when a certain temperature is reached. Detergents packaged in bags made of water-soluble film are described in large numbers in the prior art. For example, German patent application DE 198 31 703 discloses a portioned detergent or cleaning agent preparation in a bag made of water-soluble film, in particular in a bag made of (optionally acetalized) polyvinyl alcohol (PVAL), in which at least 70% by weight of the particles of the detergent or detergent preparation have particle sizes> 800 μm.

There are already numerous processes in the prior art for producing water-soluble detergent portions, which in principle can also be used in the context of the present invention. The best known processes are the tubular film processes with horizontal and vertical sealing seams. The thermoforming process (deep-drawing process), as described, for example, in WO-Al 00/55068, is also suitable for the production of plastic bags or dimensionally stable detergent portions. However, the water-soluble casings do not necessarily have to consist of a film material, but can also represent dimensionally stable containers which can be obtained, for example, by means of an injection molding process. A known process for the production of water-soluble Injection molded hollow bodies containing detergents and / or cleaning agents are described, for example, in WO-Al 01/36290.

Furthermore, methods are known in the prior art for producing water-soluble capsules from polyvinyl alcohol or gelatin, which in principle offer the possibility of providing capsules with a high degree of filling. The processes are based on the fact that the water-soluble polymer is introduced into a shaping cavity. The capsules are filled and sealed either synchronously or in successive steps, in the latter case the capsules being filled through a small opening. Methods in which the filling and sealing run in parallel are described, for example, in WO 97/35537. The capsules are filled by means of a filling wedge, which is arranged above two counter-rotating drums, which have spherical half-scales on their surface. The drums carry polymer tapes that cover the spherical half-shell cavities. Sealing takes place at the positions where the polymer tape of one drum meets the polymer tape of the opposite drum. At the same time, the filling material is injected into the capsule that forms, the injection pressure of the filling liquid pressing the polymer tapes into the spherical half-shell cavities. A process for the production of water-soluble capsules, in which the filling and then the sealing is carried out, is disclosed in WO 01/64421. The manufacturing process is based on the so-called Bottle-Pack ^® process, as described, for example, in German published patent application DE 14 114 69. Here, a tube-like preform is guided into a two-part cavity. The cavity is closed, the lower tube section being sealed, then the tube is inflated to form the capsule shape in the cavity, filled and finally sealed.

The shell material used for the production of the water-soluble portion is preferably a water-soluble polymeric thermoplastic, particularly preferably selected from the group (optionally partially acetalized) polyvinyl alcohol, polyvinyl alcohol copolymers, polyvinylpyrrolidone, poly ethylene oxide, gelatin, cellulose and their derivatives, starch and their derivatives, Blends and composites, inorganic salts and Mixtures of the materials mentioned, preferably hydroxypropylmethyl cellulose and / or polyvinyl alcohol blends.

In one embodiment of the invention, the covering material can also consist wholly or partly of the cellulose ether to be used in the textile care products according to the invention.

The polyvinyl alcohols described above are commercially available, for example under the trade name Mowiol ^® (Clariant). In the present invention, particularly suitable polyvinyl alcohols are, for example, Mowiol ^® 3-83, Mowiol ^® 4-88, Mowiol ^® 5-88, Mowiol ^® 8-88 and Clariant L648.

The water-soluble thermoplastic used to prepare the portion can additionally optionally comprise polymers selected from the group comprising polymers containing acrylic acid, polyacrylamides, oxazoline polymers. Polystyrene sulfonates, polyurethanes, polyesters, polyethers and / or mixtures of the above polymers. It is preferred if the water-soluble thermoplastic used comprises a polyvinyl alcohol whose degree of hydrolysis is 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol% and in particular 82 to 88 mol%. It is further preferred that the water-soluble thermoplastic used comprises a polyvinyl alcohol, the molecular weight of which ranges from 10,000 to 100,000 gmol ^"1 , preferably from 11,000 to 90,000 gmol ^{" 1} , particularly preferably from 12,000 to 80,000 gmol ^"1 and in particular from 13,000 to 70,000 gmol ^"1 lies. It is further preferred if the thermoplastics in amounts of at least 50% by weight, preferably at least 70% by weight, particularly preferably at least 80% by weight and in particular at least 90% by weight, in each case based on the weight of the water-soluble polymeric thermoplastic. The polymeric thermoplastics can contain plasticizers to improve their machinability. This can be particularly advantageous if polyvinyl alcohol or partially hydrolyzed polyvinyl acetate has been selected as the polymer material for the portion. Glycerin, triethanolamine, ethylene glycol, propylene glycol, diethylene or dipropylene glycol, diethanolamine and methyldiethylamine have proven particularly useful as plasticizers. It is advantageous if the polymeric thermoplastics Plasticizing auxiliaries in amounts of at least> 0% by weight, preferably of> 10% by weight, particularly preferably of> 20% by weight and in particular of> 30% by weight, in each case based on the weight of the wrapping material.

Another object of the invention is the use of a cellulose ether to be used according to the invention in a textile care agent to reduce the pill formation of textile fabrics.

Another object of the invention is the use of a cellulose ether to be used according to the invention in a textile care agent for facilitating the ironing of textile fabrics.

It was also surprisingly found that the cellulose ethers to be used according to the invention not only reduce the formation of creases and ensure a smooth textile surface, but also considerably improve the soft hand of the treated textiles.

Another object of the invention is therefore the use of a cellulose ether to be used according to the invention in a textile care agent for reducing creases, smoothing and improving the soft feel of textile fabrics.

Another object of the invention is a conditioning substrate, which is a substrate that is impregnated and / or impregnated with the textile care agent according to the invention.

The substrate material consists of porous materials that are capable of reversibly dispensing and dispensing an impregnating liquid. Both three-dimensional structures, such as sponges, but preferably porous, flat cloths are suitable for this. They can consist of a fibrous or cellular flexible material which has sufficient thermal stability for use in the dryer and which has sufficient amounts of an impregnating or coating agent can hold back in order to effectively condition substances without causing any significant leakage or bleeding of the agent during storage. These wipes include wipes made of woven and non-woven synthetic and natural fibers, felt, paper or foam, such as hydrophilic polyurethane foam.

Conventional cloths made of non-woven material (nonwovens) are preferably used here. Nonwovens are generally defined as adhesively bonded fibrous products that have a mat or layered fiber structure, or those that include fiber mats in which the fibers are randomly or randomly distributed. The fibers can be of natural origin, such as wool, silk, jute, hemp, cotton, linen, sisal or ramie; or have been produced synthetically, such as rayon, cellulose esters, polyvinyl derivatives, polyolefins, polyamides, viscose or polyester. In general, any fiber diameter or titer is suitable for the present invention. Preferred conditioning substrates according to the invention consist of a nonwoven material which contains cellulose. Due to the random or statistical arrangement of fibers in the non-woven material, which give excellent strength in all directions, the non-woven fabrics used here do not tend to tear or disintegrate when used, for example, in a household dryer. Examples of non-woven fabrics which are suitable as substrates in the present invention are known, for example, from WO 93/23603. Preferred porous and flat conditioning wipes consist of one or different fiber materials, in particular cotton, refined cotton, polyamide, polyester or mixtures of these. The conditioning substrates in cloth form preferably have an area of 0.2 to 0.005 m, preferably 0.15 to 0.01 m, in particular 0.1 to 0.03 cm and particularly preferably 0.09 to 0.06 m on. The grammage of the material is usually between 20 and 500 g / m, preferably from 25 to 200 g / m, in particular from 30 to 100 g / m and particularly preferably from 40 to 80 g / m ² .

Another object of the invention is a conditioning method for conditioning moist textiles by means of the conditioning substrate according to the invention. The conditioning process is carried out by using the conditioning substrate according to the invention together with moist textiles, for example from a previous washing process, in a textile drying process. The textile drying process usually takes place in a device for drying textiles, preferably in a household clothes dryer.

Further objects of the invention are methods for reducing the formation of lint, for reducing the formation of pills, for easing the ironing, for reducing creases, smoothing and / or improving the soft feel of textile fabrics by bringing textile fabrics into contact with a textile care agent and / or a conditioning substrate according to the invention in a textile cleaning process and / or textile drying process.

In their conditioning aspect, the textile care agents according to the invention can be put directly with the damp laundry into a household dryer and / or a washing machine.

The textile care products according to the invention can be prepared by simply mixing and stirring the individual components, which are known to the person skilled in the art. The cellulose ethers to be used according to the invention can be admixed, compounded or granulated, mixed or tableted or pelletized as a solution or slurry, preferably in aqueous form, with an especially liquid agent and / or as a dried powder, preferably onto a detergent component as a carrier.

Examples

Table 1 shows the liquid formulation M1 according to the invention and the comparison formulation VI. All information is given in percent by weight, based in each case on the total agent.

Table 1

^ Quaternized hydroxyethyl cellulose (Ucare® LK, manufacturer Dow Chemicals)

The test textiles given in Table 2 below were washed with 120 g of the respective agent [water hardness: 16 ° dH] (Miele W985; 40 ° C / white washing program / spinning: 900 rpm) and then dried (hanging on a line for 2 days in the climate room at 20 ° C and 65% humidity).

The washing and drying cycles were repeated 4 times each (ie a total of 5 washing / drying cycles). The textile to be tested was stretched in a dynamometer (Hounsfield H5KS) by 80% of the original length for 1 minute, then relaxed for 3 minutes and then the remaining stretch was measured. Table 2 below shows the reduction in the residual elongation (S) by using the agent Ml in relation to the residual elongation (S ₀ ) of the textile when using VI according to the formula

Reduction of the residual elongation = 100 x (S ₀ - S) / S ₀ specified.

Table 2: Reduction of the residual elongation

It can be seen that the use of the agent according to the invention leads to a significant improvement in the elasticity.

Example 2: Determination of the degree of creasing of textiles

Table 3 shows the universal detergent formulation M2 according to the invention and the comparison formulation V2. All information is given in percent by weight, based in each case on the total agent. Table 3

[a] Quaternized hydroxyethyl cellulose (Ucare® JR 30M, manufacturer Dow Chemicals)

The determination of the creasing was based on the AATCC Test 124 (American Association of Textile and Color Chemistry) after the washing and subsequent drying process, with a panel of five people assessing the creasing rank of the test fabrics against crumpled standard fabrics (AATCC 124). The grade 5 is given for crease-free fabric and the grade 1 for heavily crumpled fabric. The overall grade represents the arithmetic mean of the ratings. The test fabrics (textile: bleaching nettle; 100% cotton; 1.0 m * 0.9 m) were treated as follows with the formulations M2 and the comparison formulation without textile care component V2:

3 pieces of fabric were washed with 109 g of the respective formulation [water hardness: 16 ° dH] (Miele Novotronik W918; washing program: Standard Cotton / Color 60 ° C / spinning: 900 rpm) and then dried (2 days hanging on a line in a climate room at 20 ° C and 65% humidity).

The washing and drying cycles were repeated twice each (i.e. a total of 3 washing / drying cycles).

Table 4: Evaluation of the creases

The formulation M2 according to the invention shows a significantly reduced wrinkling rank compared to V2.

Example 3: Determination of the force to be used for the flattening of textiles (ironing relief)

To determine the sliding friction force that must be used to flatten a textile, a commercial iron from Rowenta P2 Professional was used by a universal testing machine from Zwick (type 2.5 / TNIP) over a pulley in the longitudinal direction at a speed of 800 mm per minute pulled over the fabric. The temperature of the iron was set to level III. The weight of the 1680 g iron was increased to 2940 g by additional weights. The force required to move the iron was measured in [N]. A test fabric (bleaching nettle, 100% cotton) was treated with the formulations M2 and V2 listed in Example 2 as follows:

6 strips of fabric were washed with 109 g of the respective agent [water hardness: 16 ° dH] (Miele Novotronik W918; washing program: Standard Cotton / Color 60 ° C / spinning: 900 rpm) and then dried (hanging on a line in a climate room at 20 ° C and 65% humidity).

The washing and drying cycles were repeated twice (i.e. a total of 3 washing / drying cycles).

Table 5: Sliding friction forces

For formulation M2 according to the invention, ironing is significantly easier compared to V2.
