„Verfahren zur Ausrüstung von Textilien mit pflegenden Ölen" "Process for finishing textiles with nourishing oils"
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Verfahren zur Ausrüstung von Textilien mit (haut)pflegenden Ölen.The invention relates to a process for finishing textiles with (skin) nourishing oils.
Stand der TechnikState of the art
Zur Ausrüstung von hochwertigen Textilien werden immer häufiger Ölmischungen verwendet, die den Textilien hautpflegende Eigenschaften verleihen. Diese Ölmischungen können der Haut bei Aufnahme über das textile Gewebe feuchtigkeitsspen- dende, glättende oder rückfettende Eigenschaften verleihen. Zur Erstausrüstung von Textilien mit Ölmischungen wird dabei üblicherweise eine wässrige Emulsion dieser Ölmischungen, die in der textilen Flotte weiter verdünnt wird, verwendet. Diese wäss- rigen Lösungen können dann beispielsweise in einem Foulard- oder Aufziehverfahren zur Ausrüstung von Textilien eingesetzt werden. Nach einigen Waschvorgängen lässt jedoch die Wirkung einer derartigen Erstausrüstung nach.For the finishing of high-quality textiles, oil blends are increasingly being used which give the textiles skin-care properties. These oil mixtures can impart moisturizing, smoothing or moisturizing properties to the skin when absorbed through the textile fabric. For the initial finishing of textiles with oil mixtures, an aqueous emulsion of these oil mixtures, which is further diluted in the textile liquor, is usually used. These aqueous solutions can then be used, for example, in a padding or drawing process for finishing textiles. After a few washes, however, the effect of such original equipment diminishes.
Daher besteht ein Bedürfnis nach einfach durchzuführenden Verfahren, welche dem Textil die besonderen Eigenschaften der Erstausrüstung zurückgeben.Therefore, there is a need for simple methods which return to the textile the unique characteristics of original equipment.
Beschreibung der ErfindungDescription of the invention
Aufgabe der vorliegenden Erfindung war es, ein Verfahren zu entwickeln, welches einfach angewendet werden kann und dem Textil im Hinblick auf hautpflegende Öle die besonderen Eigenschaften der Erstausrüstung zurückgibt. Diese Aufgabe wird in jeder Hinsicht ausgezeichnet gelöst durch das Verfahren der vorliegenden Erfindung.The object of the present invention was to develop a process which can be easily applied and which gives the textile, with regard to skin-care oils, the special properties of original equipment. This object is perfectly solved by the method of the present invention in every respect.
Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Ausrüstung von Textilien mit pflegenden Ölen, wobei man wäßrige Emulsionen mit einer Viskosität von unterhalb 200 mPas (gemessen nach Brookfield bei 20 0C) enthaltend (a) Wasser,The present invention is a process for finishing textiles with nourishing oils, wherein aqueous emulsions having a viscosity of below 200 mPas (measured according to Brookfield at 20 0 C) containing (a) water,
(b) ein oder mehrere pflegende Öle und(b) one or more caring oils and
(c) ein oder mehrere Emulgatoren auf Textilien aufbringt, mit der Maßgabe, dass die wässrige Emulsion durch Versprühen auf das Textil aufgebracht wird.(C) one or more emulsifiers applied to textiles, with the proviso that the aqueous emulsion is applied by spraying to the textile.
Gewünschtenfalls kann die wässrige Emulsion neben den Komponenten (a), (b) und (c) noch weitere Bestandteile enthalten, beispielsweise Viskositätsregulatoren, anionische Netzmittel oder Mikrokapseln. Letztere können ihrerseits mit den unterschiedlichsten Komponenten beladen sein, darunter unter anderem auch mit pflegenden Ölen. Darüber hinaus kann die wäßrige Emulsion noch spezielle, feuchtigkeitsspendende anregende Zusätze, wie z.B. Harnstoff, Glycerin, Koffein, Menthol oder Fruchtsäuren enthalten, die dann in der wässrigen Phase der O/W-Emulsion gelöst vorliegen.If desired, the aqueous emulsion may contain, in addition to components (a), (b) and (c), further constituents, for example viscosity regulators, anionic wetting agents or microcapsules. The latter can in turn be loaded with a wide variety of components, including but not limited to caring oils. In addition, the aqueous emulsion may still contain special moisturizing stimulating additives, such as e.g. Contain urea, glycerol, caffeine, menthol or fruit acids, which are then present dissolved in the aqueous phase of the O / W emulsion.
Vorzugsweise liegt die Viskosität der wässrigen Emulsionen, die durch Versprühen appliziert wird, unterhalb von 100 mPas (gemessen nach Brookfield bei 20 0C) und insbesondere unterhalb von 50 mPas und vorzugsweise unterhalb von 20 mPas.Preferably, the viscosity of the aqueous emulsions to be applied by spraying is below 100 mPas (measured according to Brookfield at 20 ° C.) and in particular below 50 mPas and preferably below 20 mPas.
Bei der erfindungsgemäß zu versprühenden Emulsion kann es sich um konventionell hergestellte O/W-Emulsionen handeln („Makroemulsionen") oder auch die dem Fachmann bekannten so genannte PIT- bzw. Mikro- oder Nanoemulsionen.The emulsion to be sprayed according to the invention may be conventionally prepared O / W emulsions ("macroemulsions") or else the so-called PIT or microemulsions or nanoemulsions known to the person skilled in the art.
Der Ölanteil der wässrigen Emulsion liegt insbesondre zwischen 1 und 50 Gew.-% - bezogen auf die gesamte Emulsion -, vorzugsweise zwischen 5 und 20 Gew.-%.The oil content of the aqueous emulsion is in particular between 1 and 50% by weight, based on the total emulsion, preferably between 5 and 20% by weight.
Die wässrige Emulsionen wird direkt auf das textile Gewebe aufgesprüht. Nach einer kurzen Trocknungszeit besitzt das textile Gewebe dann wieder die ursprünglichen hautpflegenden Eigenschaften. Sprays zur Behandlung von Textilien waren bislang nur im Pflegebereich der Textilien als solche bekannt. Als Beispiele wären Sprays als Bügelhilfe, zur Beseitigung von Geruchsspuren oder zum Aufbringen von Parfüms zu nennen.The aqueous emulsions are sprayed directly onto the textile fabric. After a short drying time, the textile fabric then regains its original skin care properties. So far, sprays for the treatment of textiles have only been known as such in the care sector of textiles. As examples, sprays should be mentioned as ironing aid, for eliminating odor traces or for applying perfumes.
Demgegenüber handelt es sich bei dem erfindungsgemäßen Verfahren darum, dass pflegende Ölkomponenten durch Versprühen auf Textilien aufgebracht werden, wobei diese Ölkomponenten dazu dienen, die menschliche Haut zu pflegen. Insbesondere eignet sich das erfindungsgemäße verfahren für die Ausrüstung solcher Textilien, die nah an der Haut getragen werden, mit pflegenden Ölen. Das Textil kann nach einer kurzen Trocknungszeit eingesetzt werden, d.h. angezogen werden. Die hautpflegende Wirkung lässt sich bei dem erfindungsgemäßen Verfahren über die aufgesprühte Menge an pflegenden Ölen streuen. Neben den hautpflegenden Eigenschaften kann das Spray dem Textil auf einen besseren Griff bzw. eine bessere Glätte verleihen, die z.B. das Anziehen von eng anliegenden Kleidungsstücken (z.B. Kompressionsstrümpfe) vereinfacht.By contrast, the process according to the invention involves the fact that nourishing oil components are applied by spraying onto textiles, these oil components serving to care for the human skin. In particular, the method according to the invention is suitable for the finishing of such textiles, which are worn close to the skin, with nourishing oils. The fabric can be used after a short drying time, i. be attracted. The skin care effect can be sprinkled in the inventive method on the sprayed amount of nourishing oils. In addition to the skin-care properties, the spray can give the textile a better feel or smoothness, e.g. tightening tight-fitting garments (e.g., compression stockings).

Zu den Verbindungen b)To the compounds b)
Wie bereits gesagt handelt es sich bei Komponente (b) um hautpflegende Öle. Dabei wird der Begriff „Öl" nicht in chemisch begrenztem Sinne von „Triglycerid" verstan- den. Vielmehr ist unter Öl eine Komponente zu verstehen, die bei Raumtemperatur ölige Konsistenz aufweist. Vorzugsweise wird Komponente (b) ausgewählt aus der Gruppe der Monoglyceride, Diglyceride, Triglyceride und Fettsäurealkylester. Dabei kann es sich sowohl um Substanzen natürlichen Ursprungs als auch um synthetische Substanzen handeln.As already mentioned, component (b) is a skin-care oil. The term "oil" is not understood in a chemically limited sense of "triglyceride". the. Rather, oil is to be understood as a component which has oily consistency at room temperature. Component (b) is preferably selected from the group of monoglycerides, diglycerides, triglycerides and fatty acid alkyl esters. These may be substances of natural origin as well as synthetic substances.
In einer Ausführungsform fungieren die Öle (b) nicht nur selbst als hautpflegende Substanzen, sondern sie können darüber hinaus auch weitere öllösliche hautpflegende Substanzen in gelöster Form enthalten.In one embodiment, the oils (b) not only function as skin-care substances themselves, but may also contain other oil-soluble skin-care substances in dissolved form.
Geeigneter Öle (b) können etwa aus folgenden Substanzklassen gewählt werden: Triglyceride, Fettsäurealkylester, Fettalkylether, Fettalkylcarbonate, verzweigte und unverzweigte Kohlenwasserstoffe. Beispiele für geeignete Substanzen sind etwa: Kokosöl, Squalan, Vitamin E, Myritol 318, Cetiol SN, Paraffine und Weissöle.Suitable oils (b) may be selected from, for example, the following classes of substances: triglycerides, fatty acid alkyl esters, fatty alkyl ethers, fatty alkyl carbonates, branched and unbranched hydrocarbons. Examples of suitable substances are: coconut oil, squalane, vitamin E, myritol 318, cetiol SN, paraffins and white oils.
Zu den Verbindungen c)To the compounds c)
Wie bereits ausgeführt handelt es sich bei den Verbindungen (c) um Emulgatoren. Diese dienen dazu, die pflegenden Öle (b) in Wasser zu emulgieren. An sich unterliegt die Auswahl der Emulgatoren keinen besonderen Einschränkungen.As already stated, the compounds (c) are emulsifiers. These are used to emulsify the caring oils (b) in water. As such, the choice of emulsifiers is not particularly limited.
Bei den Emulgatoren (c) kann es sich um klassische synthetische Emulgatoren, wie beispielsweise ethoxylierte Fettalkohole oder natürliche Emulgatoren, wie beispielsweise Lecithin handeln. Dabei sind Emulgatoren mit einem HLB- Wert im Bereich von von 8 bis 18 bevorzugt.The emulsifiers (c) may be classical synthetic emulsifiers, such as ethoxylated fatty alcohols or natural emulsifiers, such as lecithin. Emulsifiers having an HLB value in the range from 8 to 18 are preferred.
Sofern PIT-Emulsionen zum Einsatz kommen, werden vorzugsweise spezielle Emulga- torgemische, wie beispielsweise Emulgade SE-PF (Hersteller: Fa. Cognis) eingesetzt.If PIT emulsions are used, preference is given to using special emulsifier mixtures, such as Emulgade SE-PF (manufacturer: Cognis).
In einer Ausführungsform setzt man als Verbindungen c) polymere Emulgatoren ein, also Verbindungen, die als strukturell als Polymere anzusprechen sind und die im Hinblick auf die pflegenden Öle b) eine emulgierende Wirkung entfalten. Beispiel für po- lymeren Emulgatoren c), deren Monomerbausteine natürlichen Ursprungs sind, sind etwa Polymere auf Basis von Cellulose (z.B. Na-Carboxymethylcellulose) oder Polysaccharide, (zB. Xanthan Gum, Gellan Gum, Guar oder Pektine). Beispiel für polyme- ren Emulgatoren c), deren Monomerbausteine synthetischen Ursprungs sind, sind etwa Acrylate (z.B. Na-Polyacrylate), Methacrylate oder Alkylacrylate (z.B. Pemulen). Ge- wünschtenfalls können die Monomerbausteine, aus denen die Emulgatoren c) aufgebaut sind, auch chemisch modifiziert sein. In einer ganz besonders bevorzugten Aus- fuhrungsform setzt man als polymere Emulgatoren c) Verbindungen ein, die ausgewählt sind aus der Gruppe Xanthan Gum, Gellan Gum, Guar, Polyacrylate. Diese Emulgatoren können einzeln oder im Gemisch untereinander eingesetzt werden.In one embodiment, the compounds used are c) polymeric emulsifiers, ie compounds which are to be regarded as structurally polymers and which have an emulsifying effect with regard to the nourishing oils b). Example of po- Polymeric emulsifiers c) whose monomer units are of natural origin are, for example, polymers based on cellulose (eg Na-carboxymethylcellulose) or polysaccharides (eg xanthan gum, gellan gum, guar or pectins). Examples of polymeric emulsifiers c) whose monomer units are of synthetic origin are, for example, acrylates (eg Na polyacrylates), methacrylates or alkyl acrylates (eg pemulen). If desired, the monomer building blocks from which the emulsifiers c) are constructed may also be chemically modified. In a very particularly preferred embodiment, the polymeric emulsifiers c) used are compounds selected from the group consisting of xanthan gum, gellan gum, guar and polyacrylates. These emulsifiers can be used individually or mixed with each other.
Zu den Mikrokapseln m)To the microcapsules m)
Unter Mikrokapseln werden im Rahmen der vorliegenden Erfindungen prinzipiell organische Polymere mit einer bestimmten Raumstruktur verstanden (vgl. hierzu: K. La- casse und W. Baumann, Textile Chemicals, Environmental Data and Facts, Berlin 2004, Seiten 468-482). Bezüglich der Raumstruktur gilt, dass es sich um Hohlkörper handelt, die typischerweise einen Durchmesser im Bereich von 2 bis 2000 μm und einen äußeren Durchmesser im Bereich von 0,1 bis 200 μm und insbesondere 0,5 bis 150 μm haben. Auf Grund dieser Hohlkörper- Struktur können die Mikrokapseln mit Inhaltsstoffen bzw. Wirkstoffen beladen sein.In the context of the present invention, microcapsules are understood in principle to mean organic polymers having a specific spatial structure (cf., for example, K. Laccasse and W. Baumann, Textile Chemicals, Environmental Data and Facts, Berlin 2004, pages 468-482). With regard to the spatial structure, it is true that they are hollow bodies which typically have a diameter in the range of 2 to 2000 μm and an outer diameter in the range of 0.1 to 200 μm and in particular 0.5 to 150 μm. Due to this hollow body structure, the microcapsules may be loaded with ingredients or active ingredients.
Im Rahmen der vorliegenden Erfindung werden stets beladene Mikrokapseln eingesetzt, also Mikrokapseln, die mit ein oder mehreren Inhalts- bzw. Wirkstoffen beladen sind. Als Inhalts- bzw. Wirkstoffe kommen prinzipiell alle Substanzen in Betracht, die beim Tragen des Textils, das mit den beladenen Mikrokapseln ausgerüstet ist auf die Haut gelangen sollen.
