Abstract
Die vorliegende Erfindung betrifft ein Textilausrüstungsmittel zur schmutz-, öl- und wasserabweisenden Ausrüstung. Es besteht im wesentlichen aus einer Kombination aus Dispersionen von Organosilsesquioxanen und organischen Polymerharzen, die Perfluoralkylgruppen enthalten.The present invention relates to a textile finishing agent for dirt, oil and water repellent finishing. It consists essentially of a combination of dispersions of organosilsesquioxanes and organic polymer resins containing perfluoroalkyl groups.
Description
Die vorliegende Erfindung betrifft ein Textilausrüstungsmittel, das es erlaubt, Textilfasern schmutz-, öl- und wasserabweisend auszurüsten.The present invention relates to a textile finishing agent which allows textile fibers to be made dirt, oil and water repellent.
Von modernen Textilmaterialien, die z.B. als Möbelbezugstoffe oder als textiler Bodenbelag Verwendung finden, erwartet der Verbraucher günstige Eigenschaften im Hinblick auf ihre mechanische Beanspruchbarkeit, also ihre statische und dynamische Belastbarkeit und eine Unempfindlichkeit gegen Wasser, öl und/oder Schmutz.Of modern textile materials, e.g. When used as upholstery fabrics or as textile flooring, the consumer expects favorable properties with regard to their mechanical strength, i.e. their static and dynamic resilience and insensitivity to water, oil and / or dirt.
Ein großes Problem bei Textilien mit dreidimensionaler Struktur, z.B. Polmaterialien, die durch Schlingen oder aufgeschnittene Schlingen (= Velours) eine bestimmte Oberflächenstruktur besitzen und einer starken Beanspruchung während des Gebrauches ausgesetzt sind, ist die Erhaltung der Sauberkeit über einen längeren Zeitraum.A big problem with textiles with a three-dimensional structure, e.g. Pole materials that have a certain surface structure due to loops or cut loops (= velours) and are exposed to heavy wear and tear during use are intended to maintain cleanliness over a longer period of time.
Dazu müssen zwangsläufig entstandene Verschmutzungen leicht und soweit entfernbar sein, daß keine oder nur geringe Rückstände auf dem Material verbleiben, die es optisch nicht oder nur unwesentlich beeinträchtigen.Inevitably soiling must be easily and so far removed that none or only Small residues remain on the material, which do not affect it visually or only slightly.
Schmutzsubstanzen können von z.B. folgender Zusammensetzung und Konsistenz sein: öl und ölenthaltende Substanzen, flüssige, wäßrige angefärbte Substanzen, anorganische trockene pigmentartige Substanzen (Straßenstaub), wäßrige Suspensionen derselben und Mischungen der genannten Substanzen.Dirt substances can be e.g. of the following composition and consistency: oil and oil-containing substances, liquid, aqueous colored substances, inorganic dry pigment-like substances (street dust), aqueous suspensions of the same and mixtures of the substances mentioned.
Das Prinzip einer Schutzausrüstung besteht darin, daß durch das Ausrüstungsmittel den Polmaterialien hydrophobe und oleophobe Eigenschaften verliehen werden, die das Einsinken von flüssigen Verschmutzungen verhindern. Trockenschmutz haftet nicht an den Fasern und kann z.B. durch Staubsaugen von und aus der Polware leicht entfernt werden.The principle of protective equipment is that the finishing agent imparts hydrophobic and oleophobic properties to the pole materials, which prevent the sinking of liquid contaminants. Dry dirt does not adhere to the fibers and can e.g. can be easily removed by vacuuming from and from the pile.
Es sind bereits an anderer Stelle Verfahren zur Behandlung von Fasermaterialien wie Fäden, Fasern, Gewebe und Teppich beschrieben worden (z.B. DE-AS 1 594 985), um diesen Rutschsicherheit und Widerstandsfähigkeit gegen Trockenschmutz zu verleihen. Bei diesen Verfahren werden kolloidale Suspensionen von Silsequioxanen aus Einheiten der Formel RSiO3/2 mit einer Teilchengrbße von 10 bis 1000 Rngström verwendet.Processes for treating fiber materials such as threads, fibers, fabrics and carpets have already been described elsewhere (for example DE-AS 1 594 985) in order to give them slip resistance and resistance to dry dirt. In these processes, colloidal suspensions of silsequioxanes from units of the formula RSiO 3/2 with a particle size of 10 to 1000 Rngström are used.
Die dort beschriebenen Silsesquioxansuspensionen sind aber relativ unbeständig und sind nicht universell zur schmutzabweisenden und polstabilisierenden Ausrüstung geeignet.However, the silsesquioxane suspensions described there are relatively unstable and are not universally suitable for dirt-repellent and pole-stabilizing finishing.
Aus der DE-AS 1 285 978 ist ein Verfahren zum öl- und Wasserabweisendmachen sowie zur Verminderung der Aufnahme von Trockenschmutz von Textilmaterialien bekannt. Um diese Effekte zu erreichen, werden Perfluoralkylgruppenhaltige Substanzen auf die zu schützenden Materialien aufgebracht.DE-AS 1 285 978 discloses a process for rendering oil and water repellant and for reducing the absorption of dry dirt from textile materials. In order to achieve these effects, substances containing perfluoroalkyl groups are applied to the materials to be protected.
Die Ausrüstung mit Silsesquioxanen einerseits bzw. mit Perfluoralkyl-gruppenhaltigen Substanzen andererseits ließ jedoch immer noch Wünsche offen, die bisher nicht erfüllt werden konnten. Es wurden zwar bereits Versuche unternommen, Textilien mit Silico-Fluorchemikalien auszurüsten (vgl. z.B. Textil-Praxis Int., 1972, August-Heft, Seite 503 oder DE-OS 2 361 976). Dabei mußte allerdings festgestellt werden, daß zwar der Hydrophob-Effekt sehr verstärkt wird, jedoch der Oleophob-Effekt der Fluorchemikalie völlig aufgehoben wird. Dies ist wohl der Grund, weshalb bis heute keine derartige Kombination eingesetzt werden konnte.Equipping with silsesquioxanes on the one hand or with substances containing perfluoroalkyl groups, on the other hand, still left something to be desired that could not previously be fulfilled. Attempts have already been made to equip textiles with silico-fluorochemicals (see e.g. Textil-Praxis Int., 1972, August issue, page 503 or DE-OS 2 361 976). It had to be noted, however, that although the hydrophobic effect is greatly enhanced, the oleophobic effect of the fluorochemical is completely eliminated. This is probably the reason why no such combination has been used to date.
Überraschenderweise hat sich jedoch herausgestellt, daß Kombinationen bestimmter Organosilikatverbindungen mit bestimmten Perfluor-Verbindungen sich hervorragend als Textilausrüstungsmittel eignen und somit für einen universellen Schutz der Faser eingesetzt werden können.Surprisingly, however, it has been found that combinations of certain organosilicate compounds with certain perfluoro compounds are outstandingly suitable as textile finishing agents and can therefore be used for universal protection of the fiber.
Gegenstand der vorliegenden Erfindung sind somit Textilausrüstungsmittel, die gekennzeichnet sind durch einen Gehalt an
- A) 50-80 Gew.-Teilen einer wäßrigen kolloidalen Suspension von Organosilsesquioxanen aus Einheiten der Formel RSiO3/2 (R = gegebenenfalls substituierter Alkyl- bzw. Arylrest mit bis zu 7 Kohlenstoffatomen) und/oder von Cokondensaten aus Hydrolysaten von Tetraalkoxysilanen mit Organotrialkoxysilanen mit RSi03/2- bzw. Si02-Einheiten in Form eines Sols und
- B) 20-50 Gew.-Teilen einer wäßrigen Dispersion eines organischen Polymerharzes, das Perfluoralkylgruppen mit 3 bis 20 C-Atomen enthält, wobei die Perfluoralkylgruppen außer Fluoratomen höchstens 1 Wasserstoffatom- oder Chloratom pro 2 C-Atome enthalten können und wobei die Perfluoralkylkette durch Sauerstoff unterbrochen sein kann und wobei die wäßrige Dispersion 5 bis 50 Gew.-% fluorgruppenhaltiges organisches Polymerharz mit einem Fluorgehalt von 0,2 bis 40 Gew.-% aufweist.
- A ) 50-80 parts by weight of an aqueous colloidal suspension of organosilsesquioxanes from units of the formula RSiO 3/2 (R = optionally substituted alkyl or aryl radical having up to 7 carbon atoms) and / or of cocondensates from hydrolysates of tetraalkoxysilanes with organotrialkoxysilanes with RSi0 3/2 - or Si0 2 units in the form of a sol and
- B) 20-50 parts by weight of an aqueous dispersion of an organic polymer resin which contains perfluoroalkyl groups having 3 to 20 carbon atoms, the perfluoroalkyl groups apart from fluorine atoms being able to contain at most 1 hydrogen atom or chlorine atom per 2 carbon atoms and wherein the perfluoroalkyl chain contains Oxygen can be interrupted and the aqueous dispersion has 5 to 50% by weight fluorine-containing organic polymer resin with a fluorine content of 0.2 to 40% by weight.
Als Komponente A) können Organosilsequioxane, wie sie z.B. in der DE-AS 1 594 985 oder in der DE-OS 3 004 824 beschrieben sind, eingesetzt werden. Diese werden hergestellt, indem man z.B. Silane der allgemeinen Formel R-Si (OR')3 alleine oder zusammen mit Silanen (Si(OR')4 worin R substituierter oder unsubstituierter Kohlenwasserstoffrest mit 1 bis 7 Kohlenstoffatomen, dessen Substituenten Halogenatome, Amino-, Mercapto- und Epoxygruppen sein können und bis zu 95% der Reste R Methyl sind und R' einen Alkylrest mit 1 bis 4 Kohlenstoffatomen bedeutet zu einem Gemisch aus Wasser, einer Puffersubstanz, einem oberflächenaktiven Mittel und gegebenenfalls einem organischen Lösungsmittel unter Bewegung und unter sauren oder basischen Bedingungen zugegeben werden.Organosilsequioxanes as described, for example, in DE-AS 1 594 985 or in DE-OS 3 004 824 can be used as component A). These are prepared by, for example, silanes of the general formula R-Si (OR ') 3 alone or together with silanes (Si (OR') 4 in which R is substituted or unsubstituted hydrocarbon radical having 1 to 7 carbon atoms, the substituents of which are halogen atoms, amino, Mercapto and epoxy groups can be and up to 95% of the radicals R Are methyl and R 'is an alkyl radical having 1 to 4 carbon atoms to a mixture of water, a buffer substance, a surface-active agent and optionally an organic solvent with agitation and under acidic or basic conditions are added.
Zur Erzielung einer sehr engen Teilchengrößenverteilung und einer geringen durchschnittlichen Teilchengröße von etwa 200 bis 500 Rngström, wie sie zur Erzielung optimaler polstabilisierender und schmutzabweisender Effekte erforderlich sind, ist eine gleichförmige und langsame Zugabe der Silanmenge erforderlich. Die genaue Silanmenge, die zugegeben werden kann, hängt vom Substituenten R ab und davon, ob ein anionisches oder kationisches oberflächenaktives Mittel verwendet wird.In order to achieve a very narrow particle size distribution and a small average particle size of approximately 200 to 500 angstroms, as are required to achieve optimal pole-stabilizing and dirt-repellent effects, a uniform and slow addition of the amount of silane is required. The exact amount of silane that can be added depends on the substituent R and whether an anionic or cationic surfactant is used.
Es entstehen durch die gleichzeitige Hydrolyse der Silane Mischpolymerisate der Silsequioxane, worin die Einheiten in Blockform oder statistisch verteilt vorliegen können. Die bevorzugte Menge an zugesetztem Silan der allgemeinen Formel Si(OR')4 beträgt 2 bis 50 %, bezogen auf die Gesamtmenge der eingesetzten Silane, vorzugsweise 3 bis 20 % ,(Gew.-%).The simultaneous hydrolysis of the silanes results in copolymers of the silsequioxanes, in which the units can be in block form or in a random distribution. The preferred amount of added silane of the general formula Si (OR ') 4 is 2 to 50%, based on the total amount of the silanes used, preferably 3 to 20% (% by weight).
Die Silsesquioxan Dispersion ist etwa wie folgt zusammengesetzt:
Die genannten oberflächenaktiven Mittel haben die Funktion, die gebildeten Teilchen der kolloidalen Suspension zu stabilisieren.The surface-active agents mentioned have the function of stabilizing the particles formed in the colloidal suspension.
Bevorzugt werden folgende Silane eingesetzt:
- Methyltrimethoxysilan, Methyltriethoxysilan, Methyltriisopropoxysilan, Ethyltrimethoxysilan, Ethyltriethoxysilan, Propyltrimethoxysilan, Isobutyltrimethoxysilan, Isobutyltriethoxysilan, 2-Ethylbutyltriethoxysilan, Tetraethoxysilan, 2-Ethylbutoxytriethoxysilan.

Als anionische oberflächenaktive Mittel kommen aliphatische und/oder aromatische Sulfonsäuren in Betracht, beispielsweise Decyl-, Dodecyl-, Cetyl-, Stearyl-, Myristyl- oder Oleylsulfonsäuren oder deren Alkalisalze. Werden kationische oberflächenaktive Mittel verwendet, ist es vorteilhaft, Halogenide und insbesondere Chloride und Bromide zu verwenden. Andere oberflächenaktive Mittel, einschließlich solche von nichtionogener und amphoterer Natur, können in Verbindung mit den obengenannten Mitteln verwendet werden, sofern dieselben weder aufgrund ihrer Natur noch ihrer Menge einen störenden Einfluß auf die Stabilität der kolloidalen Suspension ausüben.Suitable anionic surface-active agents are aliphatic and / or aromatic sulfonic acids, for example decyl, dodecyl, cetyl, stearyl, myristyl or oleyl sulfonic acids or their alkali metal salts. If cationic surfactants are used, it is advantageous to use halides and especially chlorides and bromides. Other surfactants, including those of a non-ionic and amphoteric nature, can be used in conjunction with the above agents provided they do not interfere with the stability of the colloidal suspension due to their nature or amount.
Die oberflächenaktiven Mittel werden in einer Menge von etwa 0,01 bis etwa 15 %, bezogen auf die eingesetzte Silanmenge, eingesetzt.The surfactants are used in an amount of about 0.01 to about 15%, based on the amount of silane used.
Das Verfahren zur Herstellung der kolloidalen Suspensionen kann bei Temperaturen zwischen Raumtemperatur und 80°C durchgeführt werden; besonders bevorzugt ist der Temperaturbereich zwischen 50 und 70°C.The process for the preparation of the colloidal suspensions can be carried out at temperatures between room temperature and 80 ° C .; the temperature range between 50 and 70 ° C. is particularly preferred.

Das chemisch gebundene Fluor liegt vor in Form von Perfluoralkylliganden mit einer Kettenlänge von 3 bis 20 C-Atomen und kann außer Fluoratomen höchstens 1 Wasserstoff- oder Chloratom auf je 2 Kohlenstoffatome enthalten. Die Perfluoralkylkette kann auch durch Sauerstoffatome unterbrochen sein. Der Perfluoralkylligand ist an eine wasserunlösliche monomere oder polymere organische Verbindung gebunden. Als Beispiel für derartige Verbindungen sind Perfluoralkylliganden enthaltende Polyacrylate (vgl. z.B.

The perfluoroalkyl chain can also be interrupted by oxygen atoms. The perfluoroalkyl ligand is bound to a water-insoluble monomeric or polymeric organic compound. Examples of such compounds are polyacrylates containing perfluoroalkyl ligands (see, for example, DE-AS 1 595 017, DE-AS 1 595 018, DE-OS 2 939 549, DE-AS 2 134 978, DE-AS 2 660 200, DE- AS 1 106 960, DE-AS 1 745 089), urethanes and polyurethanes containing perfluoroalkyl ligands (see, for example, DE-OS 1 468 295, DE-AS 1 794 356, DE-PS 2 702 305, DE-AS 1 795 261, DE-OS 1 956 198), esters of aromatic and aliphatic di- and polycarboxylic acids containing perfluoroalkyl ligands (cf. for example

Neben Wasser können auch noch in geringeren Mengen organische Lösungsmittel der Dispersion zugegeben werden, um ein besonders günstiges Verhalten beim Auftragen auf die Faser zu erhalten.In addition to water, organic solvents can also be added to the dispersion in smaller amounts in order to obtain particularly favorable behavior when applied to the fiber.
Die Ausrüstung ist auf jeder Art von Fasern, also auf Fasern aus Chemiefaserstoffen auf organischer und anorganischer Basis und auf Naturfaserstoffen wirksam.The finish is effective on all types of fibers, i.e. fibers made of synthetic and organic and inorganic fibers and natural fibers.
