Textile washing articles which are polyorganosiloxane coated and / or amorphous silica-coated

The invention relates to a coated textile washing article comprising a water-insoluble textile substrate, the textile substrate being acted upon by at least one modified or unmodified polyorganosiloxane and / or at least one amorphous silicon dioxide. The invention further relates to the use of the coated textile washing article according to the invention for washing laundry and / or for preventing graying of laundry, a method for machine or manual washing of laundry using the coated textile washing article and a process for its production.

With regard to more sustainable and environmentally friendly washing processes, it is important to obtain acceptable cleaning with as few ingredients as possible. Many of the formulations for detergents used today contain, in addition to substances that enable the dirt to be detached and keep the dirt in the washing liquor, substances to reduce graying, a process which, when washing particularly light-colored textiles, causes clouding and thus a reduction in the perceived Cleanliness of the laundry leads. Keeping the dirt in the wash liquor and preventing graying is an important performance feature of modern washing systems.

Such washing systems are now available to consumers in a variety of forms. In addition to powders and granules, this offer also includes liquids, gels or portion packs (tablets or filled bags). Portion packs in particular met the consumer's desire for simplified dosing. However, detergent tablets or bags filled with liquid and / or solid detergents also have a number of disadvantages. In particular, tableted forms of offer are often characterized by delayed disintegration and thus delayed release of their ingredients due to their high compression. Therefore, the dirt that is dispersed in the wash liquor has more time to separate on a fabric.

In the case of sachets filled with liquid detergents, there is the disadvantage that incompatible ingredients cannot be formulated with one another. Often the wrapping materials used (e.g. polyvinyl alcohol) do not dissolve in time and remain as residues on the washed laundry. The dissolved polymer components also get into the environment with the wash liquor, which should be avoided.

The object of the present invention was therefore to provide an easy-to-use form for a detergent which has improved properties, in particular protects against graying and overcomes one or more of the above disadvantages.

The inventors of the present invention have surprisingly found that this is possible with the coated textile laundry article of the present invention. It was found that polyorganosiloxanes or amorphous silicon dioxide are suitable for being compatible with a textile substrate and for preventing or reducing the graying of the laundry. The textile washing article also prevents an increased entry of polymers into the washing liquor, since this is disposed of as a substrate / cloth in the household waste after the washing process.

In a first aspect, the present invention relates to a coated textile laundry article comprising a water-insoluble textile substrate, the textile substrate being acted upon by at least one modified or unmodified polyorganosiloxane and / or at least one amorphous silicon dioxide.

Furthermore, in a second aspect, the invention relates to the use of the coated textile washing article according to the present invention for washing laundry and / or for preventing graying of laundry.

In a third aspect, the present invention relates to a method for machine or manual washing of laundry using a textile washing article of the present invention.

Suitable polyorganosiloxanes are commercially available, for example, from Dow Corning, for example under the trade name AC-8066.

In various embodiments, at least one amorphous silicon dioxide is contained.

In general, all amorphous silicon dioxide known to the person skilled in the art are suitable. "Amorphous silicon dioxide" is non-crystalline or low-crystalline silicon dioxide. Amorphous silicon dioxide has no long-range order and thus differs from crystalline silicon dioxide such as quartz. Amorphous silicon dioxide comprises quartz glass made of amorphous silicon dioxide. This is made by melting crystalline silicon dioxide (naturally occurring quartz) into a non-crystalline form. Alternatively, synthetic quartz glass can be made by pyrolysis of silicon tetrachloride or vaporized quartz to form tiny droplets of amorphous quartz glass that fuse into an articulated particle structure.

Such a form of synthetic quartz glass is also known under the term pyrogenic silica. Amorphous silicon dioxide can also be precipitated from the solution to form small porous particles that can fuse together in chains. Such a form of silica is known as silica gel, which can be used to form silica aerogels. Adjusting the pH of the solution can keep the particles separate to form larger individual particles, commonly referred to as precipitated silica or silica sols, which are all forms of amorphous silica. In various embodiments, the amorphous silicon dioxide is solid at 22 ° C. and 1 bar. In various embodiments, the amorphous silica is selected from the group consisting of silica aerogels, silica gel, pyrogenic silica and combinations thereof.

In various embodiments, especially when it is pyrogenic silica, the amorphous silica can be treated with a surface treatment. Such surface treatments include, but are not limited to, polydimethylsiloxane coatings and vinyl alkoxysilanes. In general, the substances used for surface treatment make up no more than 10% by weight ("% by weight") of the total treated amorphous silica and can generally be less than 5% by weight. In a preferred embodiment, at least one treated amorphous silicon dioxide, in particular at least one treated pyrogenic silica, is used.

In a preferred embodiment, there is at least one modified or unmodified polyorganosiloxane and at least one amorphous silicon dioxide. At least one cyclic polyalkylsiloxane according to formula (Ia) as defined above and / or at least one treated amorphous silicon dioxide is preferably present. In a preferred embodiment, the at least one modified or unmodified polyorganosiloxane to the at least one amorphous silicon dioxide is contained in a weight ratio of 0.1: 99 to 10:90, preferably 0.8: 99.2 to 1.2: 98.2 .

The laundry article according to the invention can preferably be permanently equipped with the at least one modified or unmodified polyorganosiloxane and / or at least one amorphous silicon dioxide.

In the context of this invention, permanent equipment is understood to mean a permanent chemical and / or physical change in the water-insoluble substrate which imparts certain use properties, in the present case graying-inhibiting properties. This change can be made to the fibers that later form the water-insoluble textile substrate or to the water-insoluble textile substrate.

The textile substrate is given graying-inhibiting properties by applying at least one modified or unmodified polyorganosiloxane and / or at least one amorphous silicon dioxide. In one embodiment of the invention, this is fiber-reactive and forms an ionic or covalent bond with the fibers of the water-insoluble textile substrate, but preferably a van der Waals bond. The fibers can be finished, for example, by means of a so-called pull-up process, in which the fibers are treated with an application liquor, that is to say, for example, with a solution, dispersion or the like of the polyorganosiloxane and / or amorphous silicon dioxide. During the treatment, the polyorganosiloxane (s) and / or amorphous silicon dioxide (s) used from the application liquor are evenly absorbed onto the treated fibers. Alternatively, the water-insoluble textile substrate in the form of a fleece or a fabric can be dipped into the application liquor or printed or sprayed with it. The at least one polyorganosiloxane and / or at least one amorphous silicon dioxide can be applied before, after or together with the detergent composition and / or further composition which may be present.

In further different embodiments, the at least one modified or unmodified polyorganosiloxane has a molecular weight of 150 to 50,000 g / mol or 1,000 to 35,000 g / mol or 2,500 to 25,000 g / mol. The molecular weight is preferably determined by means of gel permeation chromatography using polystyrene standards.

In preferred embodiments, the at least one modified or unmodified polyorganosiloxane is contained in 0.001 to 50% by weight or 1.0 to 10.0% by weight, based on the total weight of the coated textile washing article. In particularly preferred embodiments, the total weight of modified or unmodified polyorganosiloxanes is 0.001 to 50% by weight or 1.0 to 10.0% by weight, based on the total weight of the coated textile washing article.

In preferred embodiments, the at least one amorphous silicon dioxide is contained in 0.001 to 50% by weight or 1.0 to 10.0% by weight, based on the total weight of the coated textile washing article. In particularly preferred embodiments, the total weight of amorphous silicon dioxide is 0.001 to 50% by weight or 1.0 to 10.0% by weight, based on the total weight of the coated textile washing article.

It is preferred that the textile substrate is a woven or a nonwoven. Fabrics and nonwovens have a high level of durability and good resistance, so that these textile substrates withstand the high mechanical loads during the washing process, especially in a washing machine. In preferred embodiments, the textile substrate consists of cellulose (for example cotton), polyester, polyethylene, polypropylene, polyethylene terephthalate, polybutylene terephthalate, rayon, polyacrylic, polylactic acid, lyocell, viscose or nylon or mixtures thereof. In a particularly preferred embodiment, the textile substrate contains at least two different materials, one material being unmodified polypropylene. Polypropylene fibers can bind fat and thus also counteract graying.

In a further, preferred embodiment, at least one further composition is solidified on the substrate. The substrate preferably comprises a detergent composition. In addition to the detergent composition, a further composition, for example a textile and / or skin care composition, can be present on the textile substrate. The wash article can thus be expanded by a further functionality. The compositions are preferably solidified.

It may be preferred for the detergent composition to have a color that is different from the color of the further composition, in order to also visually show consumers that the coated textile laundry article has several functionalities.

It may be preferred that the detergent composition and the further composition are arranged next to one another on the textile substrate. In another preferred embodiment, the detergent composition and the further composition are at least partially overlapping on the textile substrate.

Due to the different arrangement of the compositions, for example, different dissolution profiles and thereby release profiles of the ingredients contained can be set for the respective compositions.

The fibers or the textile substrate can preferably also be reacted with a coupling component, for example epichlorohydrin, and then with a basic nitrogen compound. Subsequent quaternization results in a dirt-trapping finish on the fibers.

In a further preferred embodiment of the invention, the fibers or the textile substrate are additionally provided with anionic groups, for example carboxyl groups and / or sulfonate groups, and then reacted with the dirt-trapping compounds.

The dirt-trapping compound preferably has a cationic charge. In particular, it is preferred that the dirt-trapping compound is a cationic polymer. Nonionic dirt-trapping compounds can, for example, be converted into cationically charged compounds with the aid of cationic coupling groups.

It is preferred that the dirt-trapping compound is selected from the group of the polyfunctional quaternary ammonium compounds, such as, for example, polyquaternium-6, polyquaternium-10 and cationic polygalactomannan derivatives, of the acrylic polymers, such as, for example, superabsorbent polyacrylates, the polyester and / or the heterocyclic Polymers, such as, for example, polyvinylpyrrolidone, polyamine-N-oxide polymers, polyvinylimidazole and copolymers of vinylpyrrolidone, Vinyl imidazole, vinyl oxazolidone, vinyl pyridine and vinyl pyridine N-oxide.

To capture different types of dirt, it can be preferred that the textile substrate is equipped with two or more dirt-trapping compounds.

The dimensions of the textile substrate in the form of a fabric should allow easy handling of the washing article and should be, for example, 10 cm × 10 cm or 20 cm × 20 cm, although other sizes are also possible. The textile substrate and thus the laundry article can be of any surface shape, for example square, rectangular, triangular, round, oval, heart-shaped, letter-shaped or word-shaped or corresponding to the representation of a brand. The textile substrate can have any color or be essentially white; its surface can be essentially smooth or textured for production reasons. The textile substrate and thus the laundry article preferably has a surface area (based on one side) of 40 cm² up to 800 cm² on. In a preferred embodiment of the invention, the textile substrate is roughened at least on parts of its surfaces and thus has an increase in surface area, as a result of which the polyorganosiloxanes are better and more stable. Due to the increase in surface area, a larger amount of the polyorganosiloxanes can be applied or attached, so that overall a larger number of binding sites for graying-acting molecules to be fixed on or is present on the textile substrate. This increases the performance of the coated textile washing article in terms of its graying-inhibiting properties.

In a further preferred embodiment, the textile substrate has an antimicrobial finish in addition to the graying-inhibiting finish. The antimicrobial treatment can be carried out, for example, by incorporating silver threads during the manufacture of the textile substrate or by applying silver compounds on or to the textile substrate, such as SILVERPLUS® (ex Rudolf Chemie).

There is preferably a solidified detergent composition on the textile substrate.

A detergent composition to be applied to the textile substrate contains, in particular if it is to be applied as a melt, constituents which are solid or wax-like at room temperature and which can be melted at a higher temperature, which in particular include surfactants and organic polymers.

The addition of small amounts of known bleach stabilizers such as, for example, phosphonates, bristles or metaborates and metasilicates, and magnesium salts such as magnesium sulfate may be useful. In a preferred embodiment, a bleach-containing detergent composition to be applied to the textile substrate contains 15% by weight to 50% by weight, in particular 18% by weight to 35% by weight, of bleaching agent containing peroxygen, in particular alkali percarbonate.

In addition to the bleach, bleach activator can be incorporated either as part of the detergent composition containing bleach or as part of another composition. In particular, compounds which give aromatic or aliphatic peroxocarboxylic acids under perhydrolysis conditions can be used as bleach activators. Preferred are polyacylated alkylenediamines, in particular tetraacetylethylene diamine (TAED), acylated triazine derivatives, in particular 1,5-diacetyl-2,4-dioxohexahydro-1,3,5-triazine (DADHT), acylated glycolurils, in particular tetraacetylglycoluril (TAGU), N- Acylimides, especially N-nonanoyl succinimide (NOSI), acylated phenol sulfonates, especially n-nonanoyl or isononanoyloxybenzene sulfonate (n- or iso-NOBS), carboxylic anhydrides, especially phthalic anhydride, and acylated polyhydric alcohols, especially triacetin, ethylene glycol diacetate and 2,5-diacetoxy-2,5-dihydrofuran.

In addition to the conventional bleach activators or in their place, so-called bleach catalysts can also be incorporated. These substances are bleach-enhancing transition metal salts or transition metal complexes such as, for example, Mn, Fe, Co, Ru or Mo salt complexes or carbonyl complexes. Mn, Fe, Co, Ru, Mo, Ti, V and Cu complexes with nitrogen-containing tripod ligands as well as Co, Fe, Cu and Ru amine complexes can also be used as bleaching catalysts. The preferred bleaching catalysts include complexes with triazacyclononane ligands, which may optionally also be mono- or polysubstituted alkyl, for example 1,4,7-trimethyl-1,4,7-triazacyclononane.

The coated textile washing article can preferably be loaded with microcapsules, in particular core-shell microcapsules, which contain an active ingredient. The microcapsules can be applied directly to the textile substrate by means of an adhesive or introduced by the detergent or additional composition. The active ingredient contained in the microcapsules is preferably a fragrance, an enzyme or a bleaching agent, particularly preferably a fragrance. All fragrances known to the person skilled in the art can be used. The microcapsule is preferably a microcapsule based on melamine, acrylate or polyvinyl alcohol.

In various embodiments, the coated textile washing article has textile substrate fibers which are provided with an active ingredient-containing, water-soluble coating. In further different embodiments, the water-soluble coating is formed from a layer-forming material which is selected from the group comprising particulate sols and water-soluble polymers. Polyvinyl alcohols are particularly suitable as water-soluble polymers.

The presence of a further composition, which is solidified on the textile substrate, can impart further functionalities to the laundry article. For example, in the case where the solidified further composition has a laundry care active ingredient, such as a textile-softening compound and / or a fragrance that can be released in the tumble dryer, a softening point higher than the solidified detergent composition and does not dissolve in the washing process, the laundry article after Washing process together with the washed laundry can be transferred to an automatic dryer. The further composition can then develop its laundry care effect there.

In a preferred embodiment, the further composition is a textile and / or skin care composition.

In this context, a textile-caring composition is understood to mean any composition that gives the textile fabrics treated with it an advantageous effect, such as, for example, a textile-softening effect, crease resistance, fragrance or the harmful or negative effects that occur during cleaning and / or conditioning and / or wearing, such as fading, etc., can be reduced.

The fabric care composition is preferably a fabric softening composition and contains, for example, an ester quat, a fabric softening clay, a cationic polymer or a mixture of these fabric softening compounds. Other suitable textile care compounds include, for example, soil release polymers, run-in preventers, anti-crease agents, color transfer inhibitors, antimicrobial agents, germicides, fungicides, antioxidants, ironing aids, phobing and impregnating agents and fragrances.

A skin-care composition is understood to mean a composition with a skin-care compound, the latter absorbing onto the textile when a textile comes into contact with the detergent and gives the skin an advantage when the textile comes into contact with skin compared to a textile which does not treat with the skin-care composition has been. This advantage can include, for example, the transfer of the skin-care compound from the textile to the skin, less water transfer from the skin to the textile or less friction on the skin surface by the textile. Suitable skin care compounds include, for example, waxes, plant extracts, higher fatty acids, higher fatty alcohols, esters, hydrocarbons, lipids, vitamins, sunscreens or phospholipids.

In one embodiment, the detergent composition and the further composition can be arranged at least partially overlapping on the textile substrate. In an alternative embodiment, the detergent composition and the further composition are arranged next to one another on the textile substrate.

In a preferred embodiment, the detergent composition has a color which is different from the color of the further composition.

In various embodiments, the entire surface of the textile substrate need not be covered with the solidified detergent composition and any further composition that may be present, as long as the detergent composition is present in at least part of the substrate surface, a zone, on the substrate.

The detergent composition and the optionally present further compositions can be applied to one or both sides of the textile substrate. The detergent composition and any further compositions which may be present are preferably applied to one side of the textile substrate. This has the particular advantage that the consumer does not have to come into direct contact with the compositions when dosing the wash article, but can easily touch the wash article on the composition-free surface.

It is possible to apply the detergent composition to the textile substrate as a liquid solution, slurry or paste, and then to carry out a drying step and to remove the slurry or solvent, for example water, to such an extent that the detergent composition dries on the textile substrate solidified. However, it is preferred to apply the detergent composition to the textile substrate as a heated melt and then to solidify it by cooling. The entire detergent composition need not be liquefied by melting, on the contrary, it is possible that the melt contains particulate solids, such as, for example, inorganic builders.

Stock solutions of a polyorganosiloxane (DOW Corning AC-8066) were prepared in water (5, 10 and 20% by weight). These were each divided into three beakers and tissue samples (viscose / Lyocell (70/30) or viscose / polylactic acid (PLA) (70/30), each 5 cm x 5 cm) were immersed in the solutions for 20 minutes. A total of six tissue samples were used for each stock solution (triple determination). The tissue samples were dried overnight on a filter sheet.

The dirt solution (FI-dirt SBL-2004) for the subsequent washing tests was produced according to the following procedure: 0.85 g of FI dirt was introduced into 6,000 g of water and about 1.5 hours at elevated temperature (stirring plate: 68 ° C) touched.

Beakers were provided on multiple stirring plates and then filled with 200 mL of the dirt solution. The equipped tissue samples and blank samples without equipment were then placed individually in a beaker. The stirring function was then switched on and stirred constantly at room temperature for 1 hour. After the samples were taken out, they were hung up to dry overnight.

The assessment was carried out visually by 3 people by comparing the finished tissue sample with the associated blank sample.<tables id="tabl0001" num="0001"><table frame="all"><title>Table 1: Dirt trapping tests with cloths that were treated with 5, 10 and 20% solution and untreated cloths as a comparison.
