WO2017191094A1 - Avoiding creasing tendency of textiles - Google Patents

Abstract

The aim of the invention is to reduce the creasing tendency of cotton or other cellulosic textiles. This is achieved by bringing the textile into contact with a polymer having carbon group-carrying substituents, said polymer being obtainable by reacting an amino polysiloxane with a cyclic carboxylic anhydride, and then optionally ironing the textile.

Description

 Knittedeigungsvermeidung in textiles

The present invention relates to the use of aminopolysiloxanes having substituents carrying carboxylic acid groups for reducing the crease tendency of textiles made of cellulosic material, a process which can be carried out in the household for wrinkle-reducing finishing of textiles made of cellulose-containing material, and laundry or laundry care products containing such polymers.

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 wrinkles is based on the sources of

Cellulose fibers and their low elastic restoring forces ("bounce") after deformation.

Therefore, it has long been common to iron cotton textiles or cellulosic textiles after washing and drying and thus to bring them into the desired shape. For the

Consumers would, however, find it advantageous to be able to reduce the formation of wrinkles in the context of textile care, which would ideally 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

Knitting-preventing 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 which is carried out with the aid of hydroxyl-bearing polymer and polycarboxylic acids, in particular butanetetracarboxylic acid (BTCA). From the article by CM. Textile Research Journal, 1988, 480-486, discloses the use of tetracarboxylic acids to crosslink cellulosic fibers. These formaldehyde-free approaches of cellulose crosslinking with the aid of polycarboxylic acids are therefore also rather unsuitable for home use since, for example, BTCA in the Arnes test shows a positive result and is therefore not toxicologically problematic.

In another approach, for example as described by M. Hashem, P. Hauser and B. Smith in Textile Research Journal, 2003, 762-766, ion pair bonds are exploited for the crosslinking of the cellulose. Cotton usually has a content of carboxyl groups of about 10 ^{~ 6} mol / g. To maximize the number of ion pair contacts, 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 DE 101 24 387 A1 finishing agents for anti-wrinkle finishing of cellulosic textiles are known which contain hydrophobically modified polyethyleneimines and / or polyvinylamines, wherein the hydrophobic modification by reaction of

Polyethyleneimines and / or polyvinylamines with long-chain carboxylic acids, alkyl halides, Alkylepoxiden, Alkylketen dimers or cyclic Dicarbonsäureanhydriden takes place.

European Patent Application EP 0 095 676 A1 discloses the use of

Aminopolysiloxanes which carry amide bonds to the Aminopolysiloxangerüst bound substituents with terminal carboxyl groups, for the fabric softening and water-repellent treatment of textile materials.

The US Pat. No. 6,277,445 B1 discloses organopolysiloxanes with

Carboxyalk (en) ylcarbonylgruppen known which can be used in the form of water-containing emulsions for waterproofing cardboard equipment.

European Patent Application EP 1 108 765 discloses the use of

carboxyl-containing side chains containing polysiloxanes for the hydrophobization of leather and furs.

It has surprisingly been found that the crease tendency of a cotton or other cellulosic textile (consisting of, or containing, for example, regenerated cellulose fibers) is brought into contact with a carboxylic acid group bearing substituent having polymer which is accessible by reacting an aminopolysiloxane with a cyclic carboxylic anhydride, and if desired, subsequent ironing can be reduced.

The invention therefore relates to the use of a polymer having carboxylic acid group-bearing substituent, which is accessible by reacting an aminopolysiloxane with a cyclic carboxylic anhydride, to reduce the tendency of creases of textiles, which consist of cellulosic material or contain cellulose-containing material.

Another object of the invention is a feasible in the household process for wrinkle reducing equipment of textiles, which consist of cellulosic material or contain cellulosic material by contacting the textile with a

Carboxylic acid-bearing substituents containing polymer which is accessible by reacting an aminopolysiloxane with a cyclic carboxylic anhydride.

The materials from which the textiles to be treated are made include cotton, regenerated cellulose fibers such as Modal or Lyocel, and blended fabrics of cotton or regenerated cellulose with other fabrics commonly used in clothing 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 to covalent bonds (ester bonds) leads. 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. Unfinished 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 amide bonds, which have entered into the amino function of the aminopolysiloxane, attached to the polymer backbone substituents which at least one carboxyl group, optionally several

Carboxyl groups, carry. In addition to optionally present non-amidated amino groups and carboxyl groups, preferably no further nucleophilic units, such as, for example, hydroxyl groups, are present in the polymer essential to the invention.

Preferred polymers according to the invention are obtained by the reaction of aminopolysiloxanes of the general formula (I)

R ₂ R ² Si-O- (SiR R ² -O-) n SiR ₂ R ² (I) wherein n is from 10 to 2,000 and each

 R is a straight-chain or branched or cyclic monovalent Ci- to Cis-hydrocarbon radical and

R ^{2 is} R or one of the groups -R ³ -NH 2 or -R ³ -NH-R ³ -NH 2 in which each

not all radicals R, not all radicals R ² , and not all radicals R ³ in the compound must be identical, with the proviso that at least 2 of the radicals R ^{2 are} not R,

accessible with cyclic carboxylic anhydrides.

Examples of the monovalent Ci-Cis hydrocarbon radicals R are methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, tert-butyl, n-pentyl, neo-pentyl, tert-pentyl, n -Hexyl, n-heptyl, n-octyl, trimethylpentyl, n-nonyl, n-decyl, n-undecyl, n-dodecyl, cycloalkyl, in particular cyclopentyl or cyclohexyl, methylcyclohexyl, aryl, especially phenyl or naphthyl , Alkaryl,

in particular o-, m- or p-toluyl, xylyl or ethylphenyl; Aralkyl radicals, in particular benzyl, o or ß-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-hexene-1-yl, 2- (3-cyclohexenyl) -ethyl and cyclododeca-4,8-dienyl. Preferred radicals with aliphatic

Double bond are vinyl, allyl, and the 5-hexenyl radical. Preferably, however, at most 1% of the hydrocarbon radicals R contain a C =C double bond. Examples of the dihydric Ci to Ci8 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 radicals or unsaturated alkylene or arylene radicals such as the hexenylene radical and phenylene radical, where the n-propylene radical and the 2- Methylpropylene radical are particularly preferred. It is preferred if, in the aminopolysiloxane, the number-average ratio of the radicals R ² which are not R to the radicals R is in the range from 1:99 to 50:50, in particular in the range from 6:94 to 20:75.

The aminopolysiloxane from which the polymer essential to the invention is obtainable preferably has an average molar mass in the range from 2000 g / mol to 30 000 g / mol, in particular from 4000 g / mol to 20000 g / mol. The average 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 a RI detector, the measurement being expediently carried out against an external standard.

Polymers which can be used according to the invention are, in particular, by reacting an abovementioned aminopolysiloxane or mixtures of different aminopolysiloxanes of this type with cyclic carboxylic anhydrides of the general formula (II),

Phthalic anhydride, trimellitic anhydride (1, 2,4-benzenetricarboxylic anhydride), naphthalene-2,3-dicarboxylic anhydride and mixtures thereof. Preferably, such molar amounts of cyclic anhydride are used based on aminopolysiloxane, that in the number average 80% to 100%, in particular 95% to 100% of the nitrogen atoms of the aminopolysiloxane are amidated. Preferably, the textile of cellulosic material at temperatures in the range of 10 ° C to 100 ° C, in particular from 20 ° C to 60 ° C, with said aminopolysiloxane with carboxylic acid-bearing substituents, said substituents are bonded via amide bonds to the polymer backbone , brought in contact. Further preferably, the textile of cellulosic material is brought into contact with the polymer over a period of 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 polymer having substituents carrying carboxylic acid groups to such an extent that a particularly high reduction of the

Cracking tendency is observed.

The implementation of the invention can be carried out, for example, by bringing textiles consisting of cellulosic material or containing cellulose-containing material into contact with a surfactant-containing aqueous preparation which contains said polymer. This can be done as part of a conventional washing process, which can be carried out by means of a household washing machine or by hand. In this case, the polymer essential to the invention is preferably used in the rinsing step, that is to say after the actual washing step. But also possible is the joint use of essential to the invention 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 washing or

A laundry care composition containing a carboxylic acid group-bearing substituent-containing polymer, which is prepared by reacting an aminopolysiloxane with a cyclic

Carboxylic anhydride is accessible.

Said polymer may be present as such, but also in the use of the user-friendly form of preparation, for example in admixture or granulated with vehicles, binders, wrapping materials, extrusion aids,

Free-flow 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.

In preferred embodiments of the invention, the polymer essential to the invention is formulated as an aqueous microemulsion. Emulsifiers, in particular nonionic emulsifiers and among these preferably alkyl polyglycol ethers, may be present if desired.

In further preferred embodiments of the invention, the polymer essential to the invention is formulated as a solution. Preferred solvents are isopropanol and ethanol, but also ethyl acetate is readily possible.

The content of polymer essential to the invention in compositions according to the invention, including the mentioned microemulsions and solutions, is preferably 0.1% by weight to 5% by weight, in particular 0.5% by weight to 1% by weight, if the agent intended for direct contact with the textile. For agents according to the invention, including those mentioned

Microemulsions and solutions which are to be dissolved or diluted before use, the content of polymer essential to the invention preferably 5 wt .-% wt .-% to 30 wt .-%, in particular 15 wt .-% to 25 wt .-%.

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 the desired shape. 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 Baumwolloder of other cellulosic material existing or containing textile with a carboxylic acid group-bearing substituent-containing polymer which is accessible by reacting an aminopolysiloxane with a cyclic carboxylic anhydride, contacted and then with a household iron in the desired shape is fixed. Ironing temperatures preferably occur in the range from 50 ° C. to 220 ° C., in particular from 100 ° C. to 160 ° C. A preferred embodiment of the method consists in bringing the polymer essential to the invention into contact with the textile in a rinsing step, preferably the last rinsing step, of a manually or mechanically executed washing process. That can do that

Inventive polymer constituent of a used in the final rinse

Being laundry detergent.

It is preferred according to the invention to apply the polymer essential to the invention in an amount in the range from 1% by weight to 2% by weight, based on the weight of the textile to be treated, on the latter. This can be achieved by applying the method according to the invention once or several times.

A cumulative effect of the invention results in some, for example 1 to 5, 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 polymer having carboxylic acid group-bearing substituents which is obtainable by reacting an aminopolysiloxane with a cyclic carboxylic anhydride in a liquid, especially aqueous, preparation which comes into contact with the textile to be treated is preferably in the range of 0.1 g / 1 to 50 g / l, in particular from 0.2 g / l to 20 g / l. Such preparations may be a liquid agent according to the invention. If desired, the agents may also be dissolved or diluted prior to use.

Such agent preferably contains synthetic anionic surfactants of the sulfate or sulfonate type, in amounts of preferably not more than 20% by weight, in particular from 0.1 to 18% by weight, in each case based on the total agent. Suitable synthetic anionic surfactants which are particularly suitable for use in such compositions are the alkyl and / or alkenyl sulfates having 8 to 22 C atoms which carry an alkali, ammonium or alkyl or hydroxyalkyl-substituted ammonium ion as counter cation. Preference is given to the derivatives of the fatty alcohols containing in particular 12 to 18 C Atoms and their branched-chain analogues, the so-called oxo alcohols. The alkyl and alkenyl sulfates can be prepared in a known manner by reaction of the corresponding alcohol component with a customary sulfating reagent, in particular sulfur trioxide or chlorosulfonic acid, and subsequent neutralization with alkali metal, ammonium or alkyl or hydroxyalkyl-substituted ammonium bases. The sulfate-type surfactants which can be used with particular preference include the abovementioned sulfated alkoxylation products of the alcohols mentioned, so-called ether sulfates.

Suitable nonionic surfactants include the alkoxylates, in particular the ethoxylates and / or propoxylates of saturated or mono- to polyunsaturated linear or branched-chain alcohols having 10 to 22 C atoms, preferably 12 to 18 C atoms. 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 ^{2 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 be used to prepare useful glycosides. Accordingly, the primary alcohols having linear octyl, decyl, dodecyl, tetradecyl, hexadecyl or octadecyl radicals and mixtures thereof are particularly suitable. Particularly preferred alkyl glycosides contain a Kokosfettalkylrest, that is, mixtures having substantially R ² = dodecyl and R ² = tetradecyl.

Injection molding process can be obtained.

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 the fact that in a shaping cavity the

water-soluble polymer is introduced. 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 lead

Polymer bands covering 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 initially the filling and then the sealing takes place, is based on the so-called Bottle-Pack ^® method. 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.
