Definitions
- aqueous emulsion polymers to the textile material to be finished in order to finish textile fabrics.
- auxiliaries applied as part of the finish serve, inter alia, as fillers, as stiffening agents, anti-slip agents, aggravating agents, agents for improving the seam tear resistance, as anti-nagging agents and the like.
- Corresponding products based on vinyl acetate, dibutyl maleate, vinyl propionate and acrylic acid esters are used in particular as plastic dispersions or emulsions. These agents also serve to vary the handle, with polyvinyl acetate dispersions giving a very hard, stiff handle.
- plasticizers can improve the grip properties, this technical solution is subject to considerable restrictions. At the temperatures used in various stages of textile treatment, the plasticizers are at least partially volatile, so that an undesirable change in the handle of the textile material occurs.
- a known plasticizer of this type is, for example, dibutyl phthalate.
- the invention is based on the object to improve the known emulsion homopolymers and / or copolymers based on vinyl acetate and its copolymers with dibutyl maleate (DBM) so that when used as textile finishing agents they have significant advantages over comparable homopolymers or copolymers of the previously known type. In particular, they should give the textile a softer and fuller feel than previously known corresponding emulsion polymers based on vinyl acetate or its copolymers with DBM.
- DBM dibutyl maleate
- the polyethylene glycol mentioned as a protective colloid By using the polyethylene glycol mentioned as a protective colloid, it is possible to produce polyvinyl acetate homo- and copolymers which, in the application area of the textile finishing agents concerned here, are distinguished by a significantly softer feel of the treated textile than when the conventional protective colloids are used - for example polyvinyl alcohol and / or cellulose derivatives . It is also of considerable advantage that the dispersions used according to the invention have a very high shear stability, as a result of which the processing of the dispersions in the context of textile finishing is promoted in important work steps.
- the aqueous polymer dispersions also contain the usual auxiliaries in small amounts, emulsifiers, buffer substances, starters for the polymerization reaction and / or salts being particularly mentioned here.
- the content of these other customary auxiliaries in the emulsion polymers is preferably not above 5% by weight, the content of emulsifiers being in particular approximately in the range from 0.5 to 3% by weight.
- Suitable conventional emulsifiers are, in particular, those based on nonionic surfactants, in particular polyethylene oxide addition products to hydrocarbon compounds having a reactive hydrogen atom, alkylphenol-EO addition products being the preferred emulsifiers.

Description
Es ist bekannt, zur Ausrüstung von textilen Flächengebilden wäßrige Emulsionspolymerisate auf das auszurüstende textile Gut aufzubringen. Diese im Rahmen der Ausrüstung aufgebrachten Hilfsstoffe dienen unter anderem als Füllmittel, als Versteifungsmittel, Schiebefestmittel, Erschwerungsmittel, Mittel zur Verbesserung der Nahtausreißfestigkeit, als Antisnaggingmittel und dergleichen. Als Kunststoffdispersionen bzw. -emulsionen werden insbesondere entsprechende Produke auf Basis von Vinylacetat, Dibutylmaleinat, Vinylpropionat und Acrylsäureestern eingesetzt. Diese Mittel dienen gleichzeitig zur Variation des Griffes, wobei mit Polyvinylacetatdispersionen ein sehr harter, steifer Griff erhalten wird. Zwar kann man durch Mitverwendung von Weichmachern die Griffeigenschaften verbessern, diese technische Lösung unterliegt aber beträchtlichen Einschränkungen. Bei den in verschiedenen Stufen der Textilbehandlung eingesetzten Temperaturen sind die Weichmacher wenigstens anteilsweise flüchtig, so daß eine unerwünschte Griffveränderung des textilen Gutes eintritt. Ein bekannter Weichmacher dieser Art ist beispielsweise Dibutylphthalat.It is known to apply aqueous emulsion polymers to the textile material to be finished in order to finish textile fabrics. These auxiliaries applied as part of the finish serve, inter alia, as fillers, as stiffening agents, anti-slip agents, aggravating agents, agents for improving the seam tear resistance, as anti-nagging agents and the like. Corresponding products based on vinyl acetate, dibutyl maleate, vinyl propionate and acrylic acid esters are used in particular as plastic dispersions or emulsions. These agents also serve to vary the handle, with polyvinyl acetate dispersions giving a very hard, stiff handle. Although the use of plasticizers can improve the grip properties, this technical solution is subject to considerable restrictions. At the temperatures used in various stages of textile treatment, the plasticizers are at least partially volatile, so that an undesirable change in the handle of the textile material occurs. A known plasticizer of this type is, for example, dibutyl phthalate.
Um die Mängel derart weichgemachter Vinylacetathomopolymerisate besser auszugleichen, ist es bekannt, Copolymerisate des Vinylacetats mit Dibutylmaleinat (DBM) einzusetzen. Auch Polyvinylpropionate liefern eine weicheren und volleren Griff beim Einsatz als Ausrüstungsmittel im Vergleich mit den Vinylacetathomopolymerisaten. Besonders weiche und volle Griffnoten werden bei der Verwendung von Polyacrylat-Emulsionen bzw. -Dispersionen eingestellt. Aus wirtschaftlichen Überlegungen heraus ist allerdings die Verwendung einer möglichst großen Menge an Vinylacetat bzw. seinen Homo- und/oder Co-Polymeren wünschenswert. Vinylacetat ist als besonders preisgünstige Komponente im Vergleich mit allen anderen hier betroffenen möglichen Monomeren für die Ausbildung des Textilausrüstungsmittels besonders begehrt.In order to better compensate for the shortcomings of such plasticized vinyl acetate homopolymers, it is known to use copolymers of vinyl acetate with dibutyl maleate (DBM). Polyvinyl propionates also provide a softer and fuller feel when used as a finishing agent in the Comparison with the vinyl acetate homopolymer. Particularly soft and full touch notes are set when using polyacrylate emulsions or dispersions. For economic reasons, however, the use of the largest possible amount of vinyl acetate or its homopolymers and / or copolymers is desirable. Vinyl acetate is a particularly inexpensive component in comparison with all other possible monomers involved here for the formation of the textile finishing agent.
Der Erfindung liegt die Aufgabe Zugrunde, die an sich bekannten Emulsionshomo- und/oder-copolymerisate auf Basis von Vinylacetat und seinen Copolymeren mit Dibutylmaleinat (DBM) so zu verbessern, daß sie bei ihrem Einsatz als Textilausrüstungsmittel wesentliche Vorteile gegenüber vergleichbaren Homo- bzw. Copolymerisaten der bisher bekannten Art besitzen. Sie sollen dabei insbesondere dem Textil einen weicheren und volleren Griff verleihen, als bisher bekannte entsprechende Emulsionspolymerisate auf Basis von Vinylacetat bzw. seinen Copolymeren mit DBM.The invention is based on the object to improve the known emulsion homopolymers and / or copolymers based on vinyl acetate and its copolymers with dibutyl maleate (DBM) so that when used as textile finishing agents they have significant advantages over comparable homopolymers or copolymers of the previously known type. In particular, they should give the textile a softer and fuller feel than previously known corresponding emulsion polymers based on vinyl acetate or its copolymers with DBM.
Die Erfindung geht von der überraschenden Feststellung aus, daß die Auswahl eines ganz bestimmten Schutzkolloides für die Emulsionspolymerisate der hier betroffenen Art die angestrebten Wirkungen von erhöhter Fülle und größerer Weichheit bei der Griffprüfung entsprechend ausgerüsteter Textilien liefert.The invention is based on the surprising finding that the selection of a very specific protective colloid for the emulsion polymers of the type concerned here provides the desired effects of increased fullness and greater softness in the handle test of appropriately equipped textiles.
Gegenstand der Erfindung sind dementsprechend Mittel zur Ausrüstung von Textilien, insbesondere textilen Flächengebilden auf Basis von Schutzkolloide neben geringen Mengen üblicher Hilfsstoffe enthaltenden Emulsionspolymerisaten des Vinylacetats und/oder seinen Copolymerisaten mit DBM, wobei die neuen Mittel dadurch gekennzeichnet sind, daß die Polymeremulsionen als Schutzkolloid Polyethylenglykol eines mittleren Molekulargewichts von etwa 3 000 bis etwa 50 000 enthalten, das wenigstens anteilsweise schon während der Emulsionspolymerisation vorgelegen hat. Bevorzugt wird das Polyethylenglykol in seiner gesamten Menge schon während der Emulsionspolymerisation bzw.-copolymerisation als Schutzkolloid eingesetzt.The invention accordingly relates to agents for finishing textiles, in particular textile fabrics based on protective colloids, in addition to small amounts Emulsion polymers containing conventional auxiliaries of vinyl acetate and / or its copolymers with DBM, the new agents being characterized in that the polymer emulsions contain, as protective colloid, polyethylene glycol of an average molecular weight of about 3,000 to about 50,000, which was at least partially present during the emulsion polymerization . The entire amount of the polyethylene glycol is preferably used as a protective colloid even during the emulsion polymerization or copolymerization.
Durch die Verwendung des genannten Polyethylenglykols als Schutzkolloid können Polyvinylacetathomo- und -copolymere hergestllt werden, die sich auf dem hier betroffenen Anwendungsgebiet der textilen Ausrüstungsmittel durch einen deutlich weicheren Griff des behandelten Textiles als bei Verwendung der üblichen Schutzkolloide - beispielsweise Polyvinylalkohol und/oder Cellulosederivate - auszeichnen. Von beträchtlichem Vorteil ist weiterhin, daß die erfindungsgemäß eingesetzten Dispersionen eine sehr hohe Scherstabilität besitzen, wodurch die Verarbeitung der Dispersionen im Rahmen der Textilausrüstung in wichtigen Arbeitsschritten begünstigt wird. Durch die Optimierung der sich auf die Weichheit und den Griff auswirkenden Parameter der erfindungsgemäßen Mittel - insbesondere durch den Gehalt an Dibutylmaleinat und durch Menge und Typ des ausgesuchten Schuzkolloids innerhalb des angegebenen Rahmens können Produkte anfallen, die hinsichtlich der Weichheit des resultierenden Griffeindruckes bei der Anwendung auf Textilien Polyvinylpropionat-Dispersionen übertreffen. Gleichzeitig erfüllen diese Produkte aber alle sonstigen Anforderungen,insbesondere hinsichtlich Feststoffgehalt, Viskosität, Verdünnbarkeit, Friktions beständigkeit und Filmbeschaffenheit. Die Möglichkeiten der besonders preisgünstigen Textilausrüstung werden dadurch wesentlich erweitert.By using the polyethylene glycol mentioned as a protective colloid, it is possible to produce polyvinyl acetate homo- and copolymers which, in the application area of the textile finishing agents concerned here, are distinguished by a significantly softer feel of the treated textile than when the conventional protective colloids are used - for example polyvinyl alcohol and / or cellulose derivatives . It is also of considerable advantage that the dispersions used according to the invention have a very high shear stability, as a result of which the processing of the dispersions in the context of textile finishing is promoted in important work steps. By optimizing the parameters of the agents according to the invention that affect the softness and feel - in particular by the content of dibutyl maleate and by the amount and type of the selected protective colloid within the specified range, products can be obtained which are sensitive to the softness of the resulting handle impression when used Textiles outperform polyvinyl propionate dispersions. At the same time, these products meet all other requirements, especially with regard to solids content, viscosity, thinnability, and friction durability and film quality. The possibilities of the particularly inexpensive textile equipment are significantly expanded.
Die Menge der als Schutzkolloid eingesetzten Polyethylenglykole liegt bevorzugt im Bereich von etwa 2 - 10 Gew.-% - bezogen auf das Gesamtgewicht des Mittels. Der Gehalt der wäßrigen Polymeremulsionen an Vinylacetatpolymerisat- bzw. -copolymerisat beträgt vorzugsweise etwa 40 bis 60 Gewichtsprozent. Wenn Copolymerisate des Vinylacetats mit DBM eingesetzt werden, so kann der DBM-Gehalt bis zu 50 Mol-% - bezogen auf die Summe von Vinylacetat und DBM - ausmachen, wobei DBM-Gehalte im Bereich von etwa 5 - 45 Mol-% besonders bevorzugt sind. Allgemein gilt, daß die Weichheit und Fülle des textilen Griffes um so größer bzw. höher wird, je höher der Gehalt an DBM im Copolymerisat gewählt ist.The amount of the polyethylene glycols used as the protective colloid is preferably in the range from about 2 to 10% by weight, based on the total weight of the composition. The vinyl acetate polymer or copolymer content of the aqueous polymer emulsions is preferably about 40 to 60 percent by weight. If copolymers of vinyl acetate with DBM are used, the DBM content can be up to 50 mol%, based on the sum of vinyl acetate and DBM, with DBM contents in the range from about 5 to 45 mol% being particularly preferred . In general, the higher the DBM content in the copolymer, the greater or greater the softness and fullness of the textile handle.
Die wäßrigen Polymerdispersionen enthalten im übrigen die üblichen Hilfsstoffe in geringen Mengen, wobei hier insbesondere Emulgatoren, Puffersubstanzen, Starter für die Polymerisationsreaktion und/oder Salze zu nennen sind. Der Gehalt der Emulsionspolymerisate an diesen sonstigen üblichen Hilfsstoffen liegt vorzugweise nicht oberhalb von 5 Gew.-%, wobei der Gehalt an Emulgatoren insbesondere etwa im Bereich von 0,5 - 3 Gew.-% liegen kann. Als übliche Emulgatoren sind insbesondere solche auf Niotensid-Basis geeignet, und zwar insbesondere Poly-ethylenoxid-Additionsprodukte an Kohlenwasserstoffverbindungen mit reaktivem Wasserstoffatom, wobei als bevorzugte Emulgatoren Alkylphenol-EO-Additionsprodukte vorliegen. Ein als Emulgator besonders geeignetes Niotensid ist z.B. das Nonylphenol x 10 EO. Es sind aber auch andere Niotenside mit verän deter EO-Kette geeignet. Besonders zweckmäßige Mengen des Nio-Tensids liegen im Bereich von 0,5 - 2 Gew.-%. Besonders geeignete Mengen des als Schutzkolloid vorliegenden Polyethylenglykols liegen im Bereich von etwa 3 bis 10 Gew.-%, wobei Polyethylenglykole eines mittleren Molekulargewichts von etwa 8 000 bis 25 000 besonders geeignet sein können.The aqueous polymer dispersions also contain the usual auxiliaries in small amounts, emulsifiers, buffer substances, starters for the polymerization reaction and / or salts being particularly mentioned here. The content of these other customary auxiliaries in the emulsion polymers is preferably not above 5% by weight, the content of emulsifiers being in particular approximately in the range from 0.5 to 3% by weight. Suitable conventional emulsifiers are, in particular, those based on nonionic surfactants, in particular polyethylene oxide addition products to hydrocarbon compounds having a reactive hydrogen atom, alkylphenol-EO addition products being the preferred emulsifiers. A nonionic surfactant that is particularly suitable as an emulsifier is, for example, nonylphenol x 10 EO. But there are also other non-ionic surfactants suitable EO chain. Particularly useful amounts of the nio-surfactant are in the range of 0.5-2% by weight. Particularly suitable amounts of the polyethylene glycol present as a protective colloid are in the range from approximately 3 to 10% by weight, polyethylene glycols having an average molecular weight of approximately 8,000 to 25,000 being particularly suitable.
In den nachfolgenden Beispielen wird zunächst die Herstellung einer Reihe von Vinylacetathomo- und -copolymerisaten im Sinne der Erfindung beschrieben, wobei wesentliche Herstellungsparameter dieser Polymeremulsionen jeweils angegeben sind. Die erfindungsgemäßen Emulsionen werden dann verglichen mit 4 Vergleichsmaterialien, die in Abwesenheit von Polyethylenglykol als Schutzkolloide hergestellt worden sind. Im Zusammenhand mit der Produktbeschreibung ist jeweils die Beurteilung der Scherstabilität, bestimmt durch Walzenauftrag nach dem Foulard-Verfahren angegeben. Hierzu gelten die folgenden Angaben:In the following examples, the production of a series of vinyl acetate homopolymers and copolymers in the sense of the invention is first described, the essential production parameters of these polymer emulsions being indicated in each case. The emulsions according to the invention are then compared with 4 comparison materials which have been produced in the absence of polyethylene glycol as protective colloids. Together with the product description, the assessment of the shear stability, determined by roller application according to the padding process, is given. The following information applies to this:
Die Dispersionen werden mittels eines Labor-Foulard auf die Gewebe aufgebracht. Dabei werden die Dispersionen unverdünnt in den Trog einer Pflatsch-Vorrichtung gegeben, die Unterwalze taucht in die Dispersion ein, der Anpreßdruck der Oberwalze wird auf 10 kp/cm eingestellt. Während 30 Minuten Laufzeit bei einer Geschwindigkeit von 30 m/min. wird die Scherstabilität der Dispersion beobachtet. Wenn nach 30 Minuten keine Ablagerungen auf der Oberwalze zu sehen sind und die Unterwalze einen gleichmäßigen Film ohne Abrisse zeigt, wird die Friktionsbeständigkeit als sehr gut beurteilt. Wenn keine Veränderungen innerhalb der ersten 10 Minuten eintreten, wird die Note gut erteilt.The dispersions are applied to the fabrics using a laboratory pad. The dispersions are placed undiluted in the trough of a plating device, the lower roller is immersed in the dispersion, the contact pressure of the upper roller is set to 10 kp / cm. During a 30-minute run at a speed of 30 m / min. the shear stability of the dispersion is observed. If after 30 minutes no deposits are visible on the top roller and the bottom roller shows a uniform film without tears, the friction resistance is rated as very good. If there are no changes within the first 10 minutes, the grade will be given well.
Treten bereits innerhalb der ersten 6 Sekunden Ablagerungen auf der Oberwalze oder Filmabrisse auf der Unterwalze auf, wird das Produkt als schlecht beurteilt.If deposits appear on the top roller or film breaks on the bottom roller within the first 6 seconds, the product is assessed as poor.
