Description

The present invention relates to the use of amino group-containing polymers having substituents carrying carboxylic acid groups for reducing creasing tendency and facilitating the ironing of textiles made of cellulosic material, as well as a household practicable process for ironing and / or wrinkle-reducing finishing of textiles made of cellulose-containing material.

Textiles made of cellulose, such as cotton or cellulose regenerated fibers (for example Modal or Lyocel) have from the consumer's point of view positive properties in terms of wearing comfort. However, a major disadvantage of these textiles is the slight creasing during wear, after washing and drying. This tendency to wrinkle is due to the swelling of the cellulose fibers and their low elastic restoring forces ("bounce") after deformation.

Therefore, it has long been common practice to iron cotton or cellulosic textiles after washing and drying and thus to bring them into the desired shape. For the consumer, however, it would be advantageous to be able to reduce the formation of wrinkles in the context of textile care, which would facilitate the ironing work or, ideally, would make ironing completely superfluous.

In the textile production one tries with the help of permanent textile equipment by a cross linking of the cellulose molecules among themselves to reduce their tendency to crease. The crosslinking of the cellulose molecules increases the elasticity of the material. The anti-crease equipment is carried out as part of the textile finishing on the raw material. However, crosslinkers used in the textile industry, such as formaldehyde-urea and formaldehyde-melamine combinations, because of their toxicity or the conditions under which they must be used, are not suitable for use in detergents or household use suitable.

Formaldehyde-free crosslinking processes for cellulose are also known, for example from US 2004/0043915 A1 a crosslinking process carried out with the aid of hydroxyl-bearing polymer and polycarboxylic acids, in particular butanetetracarboxylic acid (BTCA). From the article by CMWelch in Textile Research Journal, 1988, 480-486 is the use of tetracarboxylic acids for the crosslinking of cellulose fibers known. These formaldehyde-free approaches of cellulose crosslinking with the aid of polycarboxylic acids could be suitable from a toxicological point of view for a home application in principle. Unfortunately, the reactions require the carboxyl groups of polycarboxylic acids with the hydroxyl groups of the cellulose leading to esters, both a large amount of catalysts such as triazoles or hypophosphites or phosphites and high temperatures. This is not practical for a consumer product.

In a different approach, such as by M. Hashem, P. Hauser and B. Smith in Textile Research Journal, 2003, 762-766 described, ion pairs bonds are used for the crosslinking of cellulose. Cotton usually has a content of carboxyl groups of about 10 ^-6 mol / g. To get as many ion pair contacts as possible, the cellulose can be treated with chloro or bromoacetic acid to increase the number of its carboxyl groups. Interaction of the carboxylated cellulose with polycations, such as cationized chitosan, can result in ionic crosslinks that reduce the tendency to crease. Without the carboxylation, the effect is too small and carboxylation of cotton fabrics with haloacetic acids is not considered for home use.

From the patent application CN 1793483 A there is known a process for preparing modified cotton fibers comprising the steps of oxidizing bleached cotton fibers with periodate, removing the oxidizing agent, washing and drying the cellulose fibers, and crosslinking by reaction with an OH and NH ₂ group-containing substance such as collagen, Chitosan, silk fibroin or sericin.

From the patent application DE 101 24 387 A1 For example, finishing agents for anti-cellulite finishing of cellulosic textiles are known which contain hydrophobically modified polyethyleneimines and / or polyvinylamines, the hydrophobic modification taking place by reaction of the polyethyleneimines and / or polyvinylamines with long-chain carboxylic acids, alkyl halides, alkyl epoxides, alkyl ketene dimers or cyclic dicarboxylic acid anhydrides.

The European patent application EP 0 095 676 A1 discloses the use of aminopolysiloxanes bearing carboxy-terminated substituents attached via amide bonds to the aminopolysiloxane backbone for fabric softening and water repellent treatment of textile materials.

From the US patent US Pat. No. 6,277,445 B1 are organopolysiloxanes with Carboxyalk (en) ylcarbonylgruppen known which can be used in the form of water-containing emulsions for waterproofing cardboard equipment.

The European patent application EP 1 108 765 discloses the use of carboxyl group-containing side chain polysiloxanes for the hydrophobization of leather and furs.

It has surprisingly been found that the crease tendency of a cotton or other cellulosic textile (for example cellulose regenerated fibers) by contacting with an amino group-containing polymer having carboxylic acid group-bearing substituents, by reacting aminopolysiloxanes, polyvinylamines or polyalkyleneimines with Haloalkanoic acids is accessible, and if desired, subsequent ironing can be reduced.

The invention therefore relates to the use of an amino-containing polymer having substituents carrying carboxylic acid groups for reducing the tendency of the edges of textiles to crease of cellulose-containing material, characterized in that the polymer is accessible by reacting aminopolysiloxanes, polyvinylamines or polyalkyleneimines with haloalkanoic acids. Another object of the invention is the use of an amino-containing polymer having substituents carrying carboxylic acid groups for facilitating the ironing of textiles of cellulose-containing material, characterized in that the polymer is accessible by reacting aminopolysiloxanes, polyvinylamines or polyalkyleneimines with haloalkanoic acids.

Further objects of the invention are methods which can be carried out in the household for ironing and / or wrinkle-reducing finishing of textiles made of cellulosic material by contacting the textile with an amino group-containing polymer having substituents carrying carboxylic acid groups, characterized in that the polymer is prepared by reacting aminopolysiloxanes, Polyvinylamines or polyalkyleneimines with haloalkanoic acids is accessible.

The cellulosic materials from which the textiles to be treated are made include cotton, regenerated cellulosic fibers such as Modal or Lyocel, and blended fabrics of cotton or cellulose regenerated fibers with other apparel-based materials such as polyester and polyamide.

In preferred embodiments of the invention, the textile is ironed following treatment with said polymer with a standard household iron.

The measures of the invention significantly reduce the creasing tendency of textiles made of cellulosic material compared to the untreated starting textiles or exclusive treatment with a noncarboxylic acid-substituted amino-containing polymer. Without wishing to be bound by this theory, it is conceivable that the reaction of carboxyl groups of the polymer with hydroxyl groups of the cotton leads to covalent bonds (ester bonds). In addition, the amino groups of the polymer may possibly interact electrostatically with carboxyl groups of the cotton (ionic crosslinking). Both covalent and ionic crosslinks could lead to an increased bounce of the textile and thus to crease reduction.

The assessment of the wrinkle-free effect can be done by measuring the crease recovery angle (KEW) according to DIN 53890: 1972. Unconditioned cotton generally has crease recovery angles of about 60 ° to 80 °. By applying the present invention, KEW values of well over 80 ° are obtained.

The polymer used in the context of the invention has, in addition to the multiple amino groups and the carboxyl groups, no further nucleophilic units, such as, for example, hydroxyl groups. Polymers preferred according to the invention are selected from aminopolysiloxanes, polyvinylamines and polyalkyleneimines, such as polyethyleneimines, and mixtures thereof, which carry substituents with carboxyl groups on the nitrogen atom of the amino function. Preferably, not every nitrogen atom of the amino group-containing polymer is provided with a carboxyl group-carrying substituent, but only a fraction of the number of nitrogen atoms of the amino group-containing polymer has a carboxyl group-carrying substituent. The polymers which can be used according to the invention are obtainable by reacting aminopolysilxanes, polyvinylamines or polyalkyleneimines with haloalkanoic acids, for example bromoacetic acid. In this case, preferably only molar amounts of haloalkanoic acid are used based on amino group-containing polymer that are not introduced to all nitrogen atoms of the amino groups of the polymer carboxyl substituent substituents.

Polyvinylamines are prepared via polymer-analogous reactions, such as by hydrolysis of poly-N-vinylamides, such as poly-N-vinylformamide or poly-N-vinylacetamide, or poly-N-vinylimides, such as poly-N-vinylsuccinimide, formed by the polymerization of the corresponding Monomers are readily available, or produced by Hofmann degradation of polyacrylamide.

Polyalkyleneimines are polymers having an N-atom-containing backbone connected by alkylene groups, which may carry alkyl groups on the non-N atoms. The polyalkyleneimine preferably has primary amino functions at the ends and preferably both secondary and tertiary amino functions inside; if appropriate, it may also have only secondary amino functions on the inside, so that the result is not a branched-chain but a linear polymer. The ratio of primary to secondary amino groups in the polyalkyleneimine is preferably in the range from 1: 0.5 to 1: 1.5, in particular in the range from 1: 0.7 to 1: 1. The ratio of primary to tertiary amino groups in the polyalkyleneimine is preferably in the range from 1: 0.2 to 1: 1, in particular in the range from 1: 0.5 to 1: 0.8. The polyalkyleneimine preferably has an average molar mass in the range from 500 g / mol to 50,000 g / mol, in particular from 550 g / mol to 5000 g / mol. The mean molecular weights given here and optionally for other polymeric ingredients are weight-average molar masses M _w , which can in principle be determined by means of gel permeation chromatography with the aid of an RI detector, wherein the measurement is expediently carried out against an external standard. The N atoms in the polyalkyleneimine are preferably separated from one another by alkylene groups having 2 to 12 C atoms, in particular 2 to 6 C atoms, where not all alkylene groups must have the same C atom number. Particularly preferred are ethylene groups, 1,2-propylene groups, 1,3-propylene groups, and mixtures thereof. If desired, some of the amino functions in the polyalkyleneimine can carry 1 or 2 alkyl groups, the alkyl groups preferably being propyl and / or ethyl groups.

R ¹ ₂ R ² Si-O- (SiR ¹ R ² -O-) _n SiR ¹ ₂ R ² (I)

in the

• R ^{1 represents} straight-chain or branched or cyclic C ₁ - to C ₁₈ -hydrocarbon radicals,
• R ^{2 is} R ¹ or one of the groups -R ³ -NHR ⁴ or -R ³ -NR ⁴ -R ³ -NHR ⁴ in which
• R ^{3 is} a straight-chain or branched or cyclic divalent C _{1 to} C ₁₈ hydrocarbon radical and

• not all radicals R ¹ , not all radicals R ² , not all radicals R ³ and not all radicals R ⁴ in the compound must be the same, with the proviso that at least 2 of the radicals R ^{2 are} not R ¹ and in at least 1 , preferably in at least 2 of the non-R ¹ existent R ^{2 is} the radical R ⁴ is a group -R ⁵ is -COOX in which R ⁵ is a divalent hydrocarbon radical having 1 to 30 carbon atoms, in particular 2 to 20 carbon atoms, and X is hydrogen, Alkali metal or an ammonium group.

Examples of C ₁ -C ₁₈ -hydrocarbon radicals R ¹ are methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, n-pentyl, neopentyl, tert-pentyl, n-butyl Hexyl, n-heptyl, n-octyl, trimethylpentyl, n-nonyl, n-decyl, n-undecyl, n-dodecyl, cycloalkyl, in particular cyclopentyl or cyclohexyl, methylcyclohexyl, aryl, in particular phenyl or naphthyl, Alkaryl, in particular o-, m- or p-toluyl, xylyl or ethylphenyl; Aralkyl radicals, in particular benzyl, α- or β-phenylethyl. The hydrocarbon radicals may optionally contain a C =C double bond. Examples are alkenyl radicals such as vinyl, allyl, 5-hexenyl, E-4-hexenyl, Z-4-hexen-1-yl, 2- (3-cyclohexenyl) -ethyl and cyclododeca-4,8-dienyl. Preferred radicals having aliphatic double bond are vinyl, allyl, and the 5-hexenyl radical. Preferably, however, at most 1% of the hydrocarbon radicals R ¹ contain a C =C double bond. Examples of C ₁ - to C ₁₀ -alkyl radicals R ⁴ are the examples listed above for R ¹ for linear and cyclic alkyl radicals having at most 10 C atoms. Examples of the divalent C ₁ - to C ₁₈ -hydrocarbon radicals R ³ are saturated straight- or branched-chain or cyclic alkylene radicals such as the methylene and ethylene radical and also propylene, butylene, pentylene, hexylene, 2-methylpropylene, cyclohexylene and Octadecylene or unsaturated alkylene or arylene radicals such as the hexenylene radical and phenylene radical, wherein the n-propylene radical and the 2-methylpropylene radical are particularly preferred. Preferred examples of the divalent hydrocarbon radicals R ⁵ are the examples listed above for R ¹ , wherein the ethylene group is particularly preferred.

Preferably, the textile is made of cellulosic material at temperatures in the range of 10 ° C to 100 ° C, in particular from 20 ° C to 60 ° C, brought into contact with said amino group-containing polymer having substituents carrying carboxylic acid groups. Furthermore, the textile of cellulose-containing material is preferably brought into contact with the amino group-containing polymer having substituents carrying carboxylic acid groups over a period of from 10 minutes to 180 minutes, in particular from 30 minutes to 60 minutes. The observance of at least one of these conditions presumably leads - without wishing to be bound by this theory - to a chemical reaction of the cellulose with the amino group-containing polymer having substituents carrying carboxylic acid groups to such an extent that a particularly high reduction of the crease tendency is observed.

The implementation of the invention can be carried out, for example, by bringing textiles made of cellulosic material into contact with an aqueous preparation containing said polymer. This can be used as part of a conventional washing process, which can be carried out by means of a household washing machine or by hand. The amino group-containing polymer is preferably used in the rinsing step, that is to say after the actual washing step. However, it is also possible to jointly use amino-containing polymer and detergent in the washing step. The polymer essential to the invention may be a constituent of agents used in such washing processes, or it may be added separately to such agents or aqueous formulations containing them.

Another object of the present invention is therefore a laundry or laundry care containing an amino group-containing polymer having substituents carrying carboxylic acid groups, which is accessible by reacting aminopolysiloxanes, polyvinylamines or polyalkyleneimines with haloalkanoic acids, characterized in that it contains a nonionic surfactant.

It is possible to use said polymer as such; However, the active ingredient may also be in the use of the user by facilitating confectioning form, for example in admixture or granulated with vehicles, binders, wrapping materials, extrusion aids, flowability improvers, stabilizers, solvents, rheology modifiers and / or emulsifiers. This embodiment of the invention makes it possible for the consumer in a simple manner, the advantages of the invention by using said polymer in addition to conventional washing and / or laundry aftertreatment only to bear, if they are desirable.

Said polymer may be present in a liquid or solid agent, whereby the single dosage (pouch packaging, Pouch) of the agent is possible.

The said polymer can also be present in a liquid spray product which, after dilution with water or, in particular, undiluted, can be sprayed onto a textile. In a preferred embodiment of the invention, said polymer, in particular by spraying in the form of a liquid spray product, after washing and drying of the textile applied to this.

After the use of said polymer, it is preferable to iron the fabric once or a few times under ordinary household conditions. In particular, a particularly high effect is achieved, which particularly increases the elasticity and bounce of the textile and this particular fixed in this desired form. In the ironing subsequent washes using said polymer creasing is particularly reduced. In addition, the formation of Trageknittern is reduced when using the textiles.

The present invention is therefore also a method in which a cotton or other cellulosic material existing or containing this textile with an amino group-containing polymer having carboxylic acid group-bearing substituents, which is accessible by reacting aminopolysiloxanes, polyvinylamines or polyalkyleneimines with haloalkanoic acids, in Contact and then fixed with a household iron in the desired shape. Ironing temperatures preferably occur in the range from 50 ° C. to 220 ° C., in particular from 100 ° C. to 160 ° C.

A cumulative effect of the system according to the invention results in some, for example 1 to 5, times repeated applications. The textile does not need to be ironed after each application of the polymer according to the invention. Crease recovery angle improves from application to application. This cumulative effect allows the use of lower concentrations of the active ingredient according to the invention. Furthermore, it reduces the danger of damaging a textile by ironing in an undesired shape (for example a fold); Ironing errors can be corrected at the next application. For this reason, a dosage of the active substances essential to the invention which brings about a cumulative effect is preferred. The concentration of amino group-containing polymer having substituents carrying carboxylic acid groups in an aqueous treatment liquor is in particular in the range from 0.1 g / l to 10 g / l, more preferably from 0.2 g / l to 2 g / l.

Detergents or laundry detergents which contain the active ingredient to be used according to the invention or are used together or used in the process according to the invention may contain all customary other constituents of such agents which do not undesirably interact with the active ingredient essential to the invention.

The degree of alkoxylation of the alcohols is generally between 1 and 20, preferably between 3 and 10. They can be prepared in a known manner by reacting the corresponding alcohols with the corresponding alkylene oxides. Particularly suitable are the derivatives of fatty alcohols, although their branched-chain isomers, in particular so-called oxo alcohols, can be used for the preparation of usable alkoxylates. Useful are accordingly the alkoxylates, in particular the ethoxylates, primary alcohols with linear, in particular dodecyl, tetradecyl, hexadecyl or octadecyl radicals and mixtures thereof.

The oligomers consisting of such glycosidically linked monomers are characterized not only by the nature of the sugars contained in them by their number, the so-called Oligomerisierungsgrad. The degree of oligomerization n assumes as the value to be determined analytically generally broken numerical values; it is between 1 and 10, with the glycosides preferably used below a value of 1.5, in particular between 1.2 and 1.4. Preferred monomer building block is glucose because of its good availability. The alkyl or alkenyl moiety R ^{12 of} the glycosides preferably also originates from readily available derivatives of renewable raw materials, in particular from fatty alcohols, although their branched-chain isomers, in particular so-called oxoalcohols, can also be used for the preparation of useful glycosides.

Particularly preferred alkyl glycosides contain a Kokosfettalkylrest, that is, mixtures having substantially R ¹² = dodecyl and R ¹² = tetradecyl.

The molecular weight of homopolymers of unsaturated carboxylic acids is generally intermediate 5000 g / mol and 200000 g / mol, those of the copolymer between 2000 g / mol and 200,000 g / mol, preferably 50,000 g / mol to 120,000 g / mol, based on the free acid. A particularly preferred acrylic acid-maleic acid copolymer has a molecular weight of 50,000 g / mol to 100,000 g / mol.

For the preparation of compositions in tablet form, which may be monophasic or multiphase, monochromatic or multicolor and in particular consist of one or more layers, in particular two layers, the procedure is preferably such that all components - optionally one layer at a time - in a mixer mixed together and the mixture by means of conventional tablet presses, such as eccentric presses or rotary presses, with pressing forces in the range of about 50 to 100 kN, preferably compressed at 60 to 70 kN. Particularly in the case of multilayer tablets, it can be advantageous if at least one layer is pre-compressed.

In a particularly preferred embodiment, the agents are present, preferably in liquid form, as a portion in a completely or partially water-soluble coating. Portioning makes it easier for the consumer to dose.

The funds can be packed, for example, in foil bags. Pouches made of water-soluble film make it unnecessary for the consumer to tear open the packaging. In this way, a convenient dosing of a single, sized for a wash portion 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 hand basin, possible. The film bag surrounding the washing portion dissolves without residue when it reaches a certain temperature.

There are numerous processes in the prior art for producing water-soluble detergent portions, which are basically also useful in the context of the present invention. The best known methods are the tubular film processes with horizontal and vertical sealing seams. Further suitable for the production of film bags or dimensionally stable detergent portions is the Thermoformverrfahren (thermoforming process). However, the water-soluble envelopes need not necessarily consist of a film material, but can also represent dimensionally stable containers that can be obtained for example by means of an injection molding process.

Furthermore, methods for producing water-soluble capsules of polyvinyl alcohol or gelatin are known, which in principle offer the possibility to provide capsules with a high degree of filling. The methods are based on introducing the water-soluble polymer into a shaping cavity. The filling and sealing of the capsules takes place either synchronously or in successive steps, in which case the filling of the capsules takes place through a small opening in the latter case. The filling of the capsules takes place, for example, by a Befüllkeil, which is above two mutually rotating drums, which have ball half shells on its surface, is arranged. The drums carry polymer bands that cover the ball half-shell cavities. At the positions where the polymer band of one drum coincides with the polymer tape of the opposite drum, a seal takes place.

In parallel, the filling material is injected into the forming capsule, wherein the injection pressure of the filling liquid presses the polymer bands in the Kugelhalbschalenkavitäten. A process for the preparation of water-soluble capsules, in which first the filling and then the sealing takes place, is based on the so-called Bottle-Pack® process. In this case, a tubular preform is guided into a two-part cavity. The cavity is closed, the lower tube portion is sealed, then the tube is inflated to form the capsule shape in the cavity, filled and finally sealed.

The shell material used for the preparation of the water-soluble portion is preferably a water-soluble polymeric thermoplastic, more preferably selected from the group (optionally partially acetalized) polyvinyl alcohol, polyvinyl alcohol copolymers, polyvinylpyrrolidone, polyethylene oxide, gelatin, cellulose and derivatives thereof, starch and derivatives thereof, blends and composites, inorganic salts and mixtures of said materials, preferably hydroxypropylmethylcellulose and / or polyvinyl alcohol blends.

The water-soluble thermoplastic used to prepare the portion may additionally optionally comprise polymers selected from the group comprising acrylic acid-containing polymers, 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 makes up 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 whose molecular weight is in the range from 10,000 to 100,000 gmol ^-1 , preferably from 11,000 to 90,000 gmol ^-1 , more preferably from 12,000 to 80,000 gmol ^-1 and especially from 13,000 to 70,000 gmol ^-1 lies. It is further preferred if the thermoplastics are used in amounts of at least 50% by weight, preferably of at least 70% by weight, more preferably of at least 80% by weight and in particular of at least 90% by weight, based in each case on the weight the water-soluble polymeric thermoplastic.

Examples Example 1: Preparation of amino group-containing polymers with substituents carrying carboxylic acid groups

To 2 grams of a 6 weight percent solution of aminopropylmethylsiloxane-dimethylsiloxane copolymer (manufactured by Gelest Inc.) and 4 grams of NaOH in 100 ml of water was added 0.5 grams of bromoacetic acid and the reaction system was kept at room temperature for 24 hours. Subsequently, the pH was brought to pH 5 to 6 by addition of hydrochloric acid. After adding a few drops of the nonionic emulsifier Marlipal® O 13/60, a homogeneous emulsion was obtained.

Example 2: Wrinkling production test

Test textiles of a size of approx. 12 x 18 cm were cut out of pressed cotton fabric (type "Stella Royal" of the manufacturer Brenneth) and ironed. The aqueous emulsion of Example 1, which had been diluted to a content of 1% by weight of the polymer, was applied to the lobules to give a moisture degree of about 100% of the textile weight. The lobes were dried for 45 minutes at 25 ° C and then ironed flat with a household iron (Rowenta®, model DE634B) (temperature two points).

On the thus treated lobes (E1), the crease recovery angle were measured.

For comparison, lobes of the untreated textile (V1) were also measured.

After a crepitation time of 5 minutes or 30 minutes, the crease recovery values given in Table 1 (averages of 5-fold determinations) were obtained. Table 1: Crease recovery angle recovery time E1 V1 5 minutes 86.8 ° 67.4 ° 30 minutes 95.8 ° 75.4 °

The aminopropylmethylsiloxane-dimethylsiloxane copolymer without carboxylic acid groups (V2) used as starting material in Example 1 was applied in otherwise the same way, however from 2 weight percent formulation, tested and compared with amino group-containing polymer also having 2 weight percent formulation with carboxylic acid group carrying substituent E1. The crease recovery angles listed in Table 2 (mean values of 5-fold determinations) were observed. Table 2: Crease recovery angle recovery time E1 V2 30 minutes 92 ° 77 °

It can be seen that the aminosiloxane with the carboxyl group-carrying substituents causes a significant improvement in the crease recovery angle.
