Description

Die Erfindung betrifft eine wäßrige Dispersion, welche als Komponenten

  • a) Lecithin und
  • b) einen kationischen, Stickstoff enthaltenden, Dispergator enthält. Sie betrifft ferner die Verwendung solcher Dispersionen zur Behandlung von Fasermaterialien.
The invention relates to an aqueous dispersion, which as components
  • a) lecithin and
  • b) contains a cationic, nitrogen-containing dispersant. It also relates to the use of such dispersions for the treatment of fiber materials.

Die Behandlung von Fasermaterialien mit wäßrigen Dispersionen, welche Lecithin, von Lecithin abgeleitete Produkte oder Lecithin-ähnliche Produkte enthalten, ist bekannt, z.B. aus US-Patent 4 816 170, DE-A1 37 26 621, US 4 808 320, EP-A2 0 231 973, DE-A1 31 01 914, DE-C2 28 21 494. Diese Behandlung hat unter anderem den Zweck, den Fasermaterialien einen weichen Griff zu verleihen. Die in diesen Schriften genannten Lecithin enthaltenden Dispersionen weisen jedoch neben Vorteilen auch Nachteile auf: So sind diejenigen Dispersionen, welche ausschließlich nichtionogene oder anionische Dispergatoren oder ein Gemisch dieser beiden Dispergatortypen enthalten, dann nicht oder nur begrenzt einsetzbar, wenn Textilien nach der Jet-Technologie mit den Dispersionen ausgerüstet werden sollen. Die genannten anionischen oder nichtionogenen Dispersionen weisen wegen der hohen Anforderungen an die mechanische Belastbarkeit und vielfach zusätzlich wegen starker Schaumbildung nicht genügende Jet-Gängigkeit auf. Die aus dem Stand der Technik bekannten Lecithindispersionen, bei denen kationaktive Dispergatoren eingesetzt wurden, sind den anionischen oder nichtionogenen bezüglich der Jet-Gängigkeit überlegen; jedoch hat sich gezeigt, daß Textilien, welche mit diesen kationischen Dispersionen behandelt wurden, eine nicht befriedigende Vernähbarkeit aufweisen.The treatment of fiber materials with aqueous dispersions which contain lecithin, lecithin-derived products or lecithin-like products is known, for example from US Pat. No. 4,816,170 , DE-A1 37 26 621 , US Pat. No. 4,808,320 , EP-A2 0 231 973 , DE-A1 31 01 914 , DE-C2 28 21 494 . One of the purposes of this treatment is to give the fiber materials a soft feel. The dispersions containing lecithin mentioned in these documents, however, have advantages as well as disadvantages: For example, those dispersions which contain only nonionic or anionic dispersants or a mixture of these two types of dispersant cannot be used, or can only be used to a limited extent, if textiles made using jet technology the dispersions are to be equipped. The anionic or non-ionic dispersions mentioned have inadequate jet mobility because of the high demands placed on the mechanical strength and in many cases additionally because of the strong foam formation. The lecithin dispersions known from the prior art, in which cationic dispersants have been used, are anionic or non-ionic with regard to their ability to pass think; however, it has been shown that textiles which have been treated with these cationic dispersions have unsatisfactory sewability.

Aufgabe der vorliegenden Erfindung war es, Lecithin enthaltende wäßrige Dispersionen zur Verfügung zu stellen, welche sich zur Weichgriffausrüstung von Fasermaterialien, insbesondere Textilien, eignen, gute Jet-Gängigkeit aufweisen und eine bessere Vernähbarkeit der behandelten Textilien gewährleisten als im Fall der Behandlung der Textilien mit bekannten wäßrigen Lecithindispersionen.It was an object of the present invention to provide lecithin-containing aqueous dispersions which are suitable for softening fiber materials, in particular textiles, are easy to jet and ensure better sewability of the treated textiles than in the case of treating the textiles with known ones aqueous lecithin dispersions.

Die Aufgabe wurde gelöst durch eine wäßrige Dispersion gemäß Oberbegriff von Anspruch 1, die dadurch gekennzeichnet ist, daß sie zusätzlich als Komponente c) ein dispergiertes Polyethylen enthält.The object was achieved by an aqueous dispersion according to the preamble of claim 1, which is characterized in that it additionally contains a dispersed polyethylene as component c).

Die erfindungsgemäßen Dispersionen besitzen folgende Vorteile:

  • 1. Sie vermitteln den damit behandelten Fasermaterialien einen angenehm weichen Griff, der insbesondere im Fall von Textilien häufig erwünscht ist.
  • 2. Sie neigen nicht oder nur in geringem Ausmaß zur Schaumbildung und sind mechanisch sehr stabil. Daher ist Jet-Gängigkeit gewährleistet, d.h. die Behandlung der Fasermaterialien mit erfindungsgemäßen Dispersionen kann nach der Jet-Technologie erfolgen.
  • 3. Die mit erfindungsgemäßen Dispersionen behandelten Fasermaterialien weisen gute Vernähbarkeit auf.
  • 4. Die erfindungsgemäßen Dispersionen lassen sich mittels eines Ausziehverfahrens auf Fasermaterialien aufbringen.
The dispersions according to the invention have the following advantages:
  • 1. They impart a pleasantly soft feel to the fiber materials treated with it, which is often desirable, particularly in the case of textiles.
  • 2. They do not tend to foam or only to a small extent and are mechanically very stable. It is therefore possible to jet, ie the treatment of the fiber materials with dispersions according to the invention can be carried out using jet technology.
  • 3. The fiber materials treated with dispersions according to the invention have good sewability.
  • 4. The dispersions according to the invention can be applied to fiber materials by means of an exhaust process.

Die erfindungsgemäßen Dispersionen enthalten als Komponente a) Lecithin. Unter den Begriff Lecithin fallen eine Reihe bekannter Produkte, welche aus Naturprodukten, wie z.B. Eiern und Sojabohnen, gewonnen werden können. Eine vorteilhafte Quelle für Lecithin sind Sojabohnen. Lecithine sind Phospholipide, in denen Phosphorsäure mit Cholin einerseits und mit Glycerin andererseits verestert ist. Zur Definition der Lecithine siehe "Römpps Chemie-Lexikon". 8. Auflage 1983, Seite 2338 - 2339, Franckh'sche Verlagshandlung, Stuttgart, DE. Lecithine und wäßrige Dispersionen von Lecithinen sind handelsübliche Produkte. Auf dem Markt erhältliche wäßrige Dispersionen von Lecithin können für die Herstellung erfindungsgemäßer Dispersionen verwendet werden, wenn diese handelsüblichen Dispersionen unter Verwendung kationischer und/oder nichtionogener Dispergatoren hergestellt worden sind. Falls handelsübliche Lecithindispersionen nur nichtionogene Dispergatoren enthalten, müssen kationische Dispergatoren und ein Polyethylen der unten näher beschriebenen Art hinzugefügt werden. Falls eine handelsübliche Lecithindispersion bereits kationische Dispergatoren enthält, muß noch ein Polyethylen hinzugefügt werden; es können aber auch ggf. noch weitere kationische und/oder nichtionogene Dispergatoren zugesetzt werden.
Die EP 0 237 880 beschreibt die Gewinnung von Lecithin und dessen Dispergierung in Wasser mit Hilfe kationischer Dispergatoren. Die dort genannten kationischen Lecithindispersionen können zur Herstellung erfindungsgemäßer Dispersionen verwendet werden. Geeignet als Komponente a) für die Herstellung erfindungsgemäßer Dispersionen sind ferner Lecithine, wie sie im druckschriftlichen Stand der Technik beschrieben sind, z.B. in US-Patent 4 816 170 und in DE-A1 37 26 621.The dispersions according to the invention contain lecithin as component a). The term lecithin includes a number of known products which can be obtained from natural products such as eggs and soybeans. Soybeans are an advantageous source of lecithin. Lecithins are phospholipids in which phosphoric acid is esterified with choline on the one hand and with glycerin on the other. For the definition of the lecithins see "Römpps Chemie-Lexikon". 8th edition 1983, pages 2338 - 2339, Franckh'sche Verlagshandlung, Stuttgart, DE. Lecithins and aqueous dispersions of lecithins are commercially available products. Aqueous dispersions of lecithin available on the market can be used for the preparation of dispersions according to the invention if these commercial dispersions have been prepared using cationic and / or nonionic dispersants. If commercially available Lecithin dispersions containing only nonionic dispersants, cationic dispersants and a polyethylene of the type described in more detail below must be added. If a commercially available lecithin dispersion already contains cationic dispersants, a polyethylene must be added; However, other cationic and / or nonionic dispersants can also be added if necessary.
EP 0 237 880 describes the extraction of lecithin and its dispersion in water with the aid of cationic dispersants. The cationic lecithin dispersions mentioned there can be used to prepare dispersions according to the invention. Also suitable as component a) for the preparation of dispersions according to the invention are lecithins as described in the prior art document, for example in US Pat. No. 4,816,170 and in DE-A1 37 26 621.

Die erfindungsgemäßen Dispersionen enthalten als Komponente b) mindestens einen kationischen, Stickstoff enthaltenden, Dispergator. Es können jedoch auch mehrere Dispergatoren vorliegen, die alle kationisch sein können oder von denen ein Teil kationisch und der Rest nichtionogen ist.The dispersions according to the invention contain, as component b), at least one cationic, nitrogen-containing dispersant. However, there may also be several dispersants, all of which can be cationic or some of which are cationic and the rest of which are nonionic.

Der als Komponente b) der erfindungsgemäßen Dispersionen dienende Dispergator bewirkt die Dispergierung des Lecithins und enthält mindestens ein Stickstoffatom, das für den kationischen Charakter verantwortlich ist. Dieses Stickstoffatom kann Teil eines organischen heterocyclischen Ringes sein, z.B. können Imidazoliniumsalze als Dispergatoren dienen. Besonders geeignet als Komponente b) der erfindungsgemäßen Dispersionen sind jedoch Salze der allgemeinen Formel

worin R1 für Wasserstoff oder einen Rest R2, R3 oder R4 steht, worin R2, R3, R4 unabhängig voneinander für einen offenkettigen gesättigten oder ungesättigten Kohlenwasserstoffrest mit 1 bis 24 Kohlenstoffatomen stehen, der durch eine -CO-N(R5)- oder eine -N(R5)-Brücke unterbrochen sein und eine OH-Gruppe als Substituenten aufweisen kann, wobei R5 für Wasserstoff oder einen Alkylrest mit 1 bis 4 Kohlenstoffatomen steht und worin X⁻ für ein Anion steht und n die Wertigkeit dieses Anions bedeutet.The dispersant serving as component b) of the dispersions according to the invention causes the lecithin to be dispersed and contains at least one nitrogen atom which is responsible for the cationic character. This nitrogen atom can be part of an organic heterocyclic ring, for example imidazolinium salts can serve as dispersants. However, salts of the general formula are particularly suitable as component b) of the dispersions according to the invention
Figure imgb0001
in which R1 represents hydrogen or a radical R2, R3 or R4, in which R2, R3, R4 independently of one another represent an open-chain saturated or unsaturated hydrocarbon radical having 1 to 24 carbon atoms, which is represented by a -CO-N (R5) - or a - N (R5) bridge may be interrupted and may have an OH group as a substituent, where R5 is hydrogen or an alkyl radical having 1 to 4 carbon atoms and where X⁻ is an anion and n is the valence of this anion.

Das Anion X⁻ steht beispielsweise für ein Halogenidion oder für ein anderes Anion einer starken Mineralsäure.The anion X⁻ stands for example for a halide ion or for another anion of a strong mineral acid.

Es wurde gefunden, daß besonders stabile erfindungsgemäße Dispersionen erhalten werden, wenn der als Komponente b) verwendete Dispergator wasserlöslich ist, insbesondere, wenn er eine Löslichkeit von mindestens 100 g/l in Wasser bei 20°C besitzt.It has been found that particularly stable dispersions according to the invention are obtained if the dispersant used as component b) is water-soluble, in particular if it has a solubility of at least 100 g / l in water at 20 ° C.

Besonders gut geeignete Dispergatoren sind solche, bei denen in der oben angegebenen Formel (R1 R2 R3 R4 N)n ⁺ X⁻ drei der 4 an N gebundenen Reste jeweils einen kürzerkettigen Alkylrest mit 1 bis 6 Kohlenstoffatomen bedeuten, der vierte einen längerkettigen, gesättigten oder ungesättigten Kohlenwasserstoffrest bedeutet, der durch eine Säureamidbrücke (-CO-NH-) unterbrochen ist und der eine OH-Gruppe als Substituenten aufweist. Außerdem sind unter den Vertretern dieser Dispergatoren solche bevorzugt, deren Anion einwertig ist, bei denen also n in obiger Formel für 1 steht. Weitere geeignete kationaktive Dispergatoren sind in der EP 0 237 880 beschrieben.Particularly suitable dispersants are those in which, in the formula given above (R1 R2 R3 R4 N) n ⁺ X⁻, three of the 4 radicals bonded to N each represent a shorter-chain alkyl radical having 1 to 6 carbon atoms, the fourth a longer-chain, saturated or unsaturated hydrocarbon radical, which is interrupted by an acid amide bridge (-CO-NH-) and which has an OH group as a substituent. In addition, among the representatives of these dispersants, preference is given to those whose anion is monovalent, in which n is 1 in the above formula. Further suitable cationic dispersants are described in EP 0 237 880.

Die erfindungsgemäßen Dispersionen enthalten als Komponente c) ein dispergiertes Polyethylen. Es wurde gefunden, daß durch den Zusatz der Komponente c) erreicht wird, daß sich mit den Dispersionen behandelte Textilien besser vernähen lassen als im Fall einer Behandlung mit Dispersionen, welche nur die Komponenten a) und b) enthalten.
Komponente c) muß in dispergierter Form vorliegen. Damit dies möglich ist, muß es sich um ein modifiziertes Polyethylen handeln. Im Zusammenhang mit der vorliegenden Erfindung wird unter dispergiertem Polyethylen ein modifiziertes Polyethylen verstanden, welches funktionelle Gruppen aufweist. Diese funktionellen Gruppen sind insbesondere saure Gruppen, vor allem COOH-Gruppen. Die Einführung saurer Gruppen in Polyethylen kann z.B. durch Oxidation des Polyethylens oder durch Copolymerisation von Ethylen mit Acrylsäure erfolgen. Entsprechend modifizierte Polyethylene mit sauren Gruppen, die eine Dispergierung in Wasser ermöglichen, sind aus dem Stand der Technik bekannt. Modifizierte dispergierbare Polyethylene, welche sich als Komponente c) für erfindungsgemäße Dispersionen eignen, sind beispielsweise beschrieben in EP-A2 0 412 324, US-Patent 4 211 815, DE-A 28 24 716, DE-A 19 25 993.The dispersions according to the invention contain a dispersed polyethylene as component c). It has been found that by adding component c) it is achieved that textiles treated with the dispersions can be sewn better than in the case of treatment with dispersions which contain only components a) and b).
Component c) must be in dispersed form. For this to be possible, it must be a modified polyethylene. In connection with the present invention, dispersed polyethylene is understood to mean a modified polyethylene which has functional groups. These functional groups are especially acidic groups, especially COOH groups. Acidic groups can be introduced into polyethylene, for example, by oxidation of the polyethylene or by copolymerization of ethylene with acrylic acid. Correspondingly modified polyethylenes with acidic groups which enable dispersion in water are known from the prior art. Modified dispersible polyethylenes which are suitable as component c) for dispersions according to the invention are described, for example, in EP-A2 0 412 324 , US Pat. No. 4 211 815 , DE-A 28 24 716 , DE-A 19 25 993 .

Besonders gut geeignet sind modifizierte, dispergierbare Polyethylene, wie sie in den Ansprüchen und in der Beschreibung der EP-A2 0 412 324 genannt sind, nämlich sauer modifizierte emulgierbare Polyethylene (Polyethylenwachse) mit einer Säurezahl von mindestens 5, einer Verseifungszahl von mindestens 10 und einer Dichte von mindestens 0,91 g/cm³ bei 20°C. Vorzugsweise liegt die Säurezahl bei 10 bis 40, die Verseifungszahl bei 15 bis 80 und die Dichte bei 0,95 bis 1,05 g/cm³. Geeignete dispergierbare oder bereits dispergierte, modifizierte Polyethylene bzw. Polyethylenwachse sind im Handel erhältlich.Modified, dispersible polyethylenes, as mentioned in the claims and in the description of EP-A2 0 412 324, are particularly suitable, namely acid-modified emulsifiable polyethylenes (polyethylene waxes) with an acid number of at least 5, a saponification number of at least 10 and one Density of at least 0.91 g / cm³ at 20 ° C. The acid number is preferably from 10 to 40, the saponification number from 15 to 80 and the density from 0.95 to 1.05 g / cm 3. Suitable dispersible or already dispersed, modified polyethylenes or polyethylene waxes are commercially available.

Erfindungsgemäße Dispersionen können nach allgemein bekannten Verfahren hergestellt werden, die für die Herstellung von Dispersionen üblich sind. Dies gilt sowohl dann, wenn erfindungsgemäße Dispersionen hergestellt werden sollen, welche nur die Komponenten a), b) und c) enthalten, als auch dann, wenn sie weitere Bestandteile enthalten sollen. In vielen Fällen ist es zweckmäßig, eine wäßrige Dispersion herzustellen, welche die Komponenten a) und b) und ggf. weitere Komponenten, nicht aber Komponente c) enthält und diese Dispersion dann mit einer separat hergestellten wäßrigen Dispersion der Komponente c) zu vereinigen. Die Herstellung der erfindungsgemäßen Dispersionen kann in üblichen Apparaturen, ggf. unter Verwendung bekannter Homogenisierungsvorrichtungen und ggf. bei erhöhten Temperaturen erfolgen.Dispersions according to the invention can be prepared by generally known processes which are customary for the preparation of dispersions. This applies both if Dispersions according to the invention are to be produced which contain only components a), b) and c), and also if they are to contain further constituents. In many cases it is expedient to prepare an aqueous dispersion which contains components a) and b) and, if appropriate, further components, but not component c), and then to combine this dispersion with a separately prepared aqueous dispersion of component c). The dispersions according to the invention can be produced in customary apparatus, if appropriate using known homogenization devices and, if appropriate, at elevated temperatures.

Es kann von Vorteil sein, wenn erfindungsgemäße Dispersionen außer kationaktiven Dispergatoren noch zusätzlich einen oder mehrere nichtionogene Dispergatoren enthalten. Dies kann dann zweckmäßig und manchmal sogar erforderlich werden, wenn den Dispersionen noch weitere Produkte zugesetzt werden sollen, welche mit kationaktiven Dispergatoren allein nicht oder nicht optimal dispergiert werden können. Eine spezielle Ausführungsform erfindungsgemäßer Dispersionen besteht daher darin, daß sie zusätzlich als Komponente d) einen nichtionogenen Dispergator oder ein Gemisch nichtionogener Dispergatoren enthält. Bei dem Gemisch kann es sich zum Beispiel um mehrere nichtionogene Dispergatoren mit unterschiedlichem Ethoxilierungsgrad oder mit unterschiedlichem HLB-Wert handeln. Als nichtionogene Dispergatoren kommen zum Beispiel bekannte handelsübliche Ethoxilierungsprodukte von Fettsäuren, Fettalkoholen oder Fettaminen in Betracht.It can be advantageous if, in addition to cationic dispersants, dispersions according to the invention additionally contain one or more nonionic dispersants. This can be expedient and sometimes even necessary if further products are to be added to the dispersions, which alone cannot be dispersed or cannot be optimally dispersed with cationic dispersants. A special embodiment of dispersions according to the invention therefore consists in additionally containing a nonionic dispersant or a mixture of nonionic dispersants as component d). The mixture can be, for example, several nonionic dispersants with different degrees of ethoxylation or with different HLB values. Known commercially available ethoxylation products of fatty acids, fatty alcohols or fatty amines can be considered as nonionic dispersants.

Obwohl die Mengenverhältnisse der Komponenten zueinander in weiten Bereichen schwanken können, ist es von Vorteil, wenn erfindungsgemäße Dispersionen die oben beschriebenen Komponenten a) bis d) in folgenden relativen Mengenverhältnissen enthalten: Komponente a): 2 bis 15 Gew.teile Komponente b): 0,5 bis 5 Gew.teile Komponente c): 0,5 bis 8 Gew.teile Komponente d): 0 bis 3 Gew.teile Although the quantitative ratios of the components to one another can vary within wide ranges, it is advantageous if dispersions according to the invention contain components a) to d) described above in the following relative quantitative ratios: Component a): 2nd to 15 parts by weight Component b): 0.5 to 5 parts by weight Component c): 0.5 to 8 parts by weight Component d): 0 to 3 parts by weight

Im Bedarfsfall können noch weitere Komponenten wie spezielle Weichgriffmittel, optische Aufheller, Cellulosevernetzer hinzugefügt werden. Die Gesamtmenge an Komponenten a) bis d) und zusätzlichen Komponenten wird zweckmäßigerweise so bemessen, daß die Dispersionen eine Konzentration von etwa 10 bis 30 Gew.% besitzen. Solche, 70 bis 90 Gew.% Wasser enthaltenden, Dispersionen sind gut lager- und transportfähig und weisen gute Stabilität auf. Vor ihrer Anwendung zur Behandlung von Fasermaterialien, wie z.B. Textilien, können sie auf niedrigere Konzentrationen verdünnt werden.If necessary, other components such as special softening agents, optical brighteners and cellulose crosslinking agents can be added. The total amount of components a) to d) and additional components is expediently such that the dispersions have a concentration of about 10 to 30% by weight. Such dispersions containing 70 to 90% by weight of water are easy to store and transport and have good stability. Before being used to treat fiber materials such as textiles, they can be diluted to lower concentrations.

Die erfindungsgemäßen Dispersionen eignen sich sehr gut zur Behandlung von Fasermaterialien, insbesondere von Flächengebilden wie Geweben oder Gewirken für den Einsatz im Textilsektor. Den Textilien wird durch die Behandlung mit den Dispersionen und nachfolgende Weiterverarbeitung nach bekannten Methoden (Trocknung, ggf. weitere Behandlung bei erhöhten Temperaturen) angenehm weicher Griff verliehen. Die Textilien weisen gute Vernähbarkeit auf. Das Aufbringen erfindungsgemäßer Dispersionen auf die Fasermaterialien kann vielfach nach dem Ausziehverfahren erfolgen, jedoch sind andere Verfahren, wie z.B. ein Foulardprozeß, nicht ausgeschlossen. Die erfindungsgemäßen Dispersionen weisen gute Jet-Gängigkeit auf, so daß auch nach dieser Technologie gearbeitet werden kann. Um spezielle Effekte, z.B. auf Cellulosematerialien zu erzielen, können den erfindungsgemäßen Dispersionen weitere Komponenten zugesetzt werden, wie bekannte Cellulosevernetzer, optische Aufheller und spezielle weitere Weichgriffmittel, wie z.B. auf Basis von Umsetzungsprodukten von Fettsäureamiden mit Alkanolaminen.The dispersions according to the invention are very well suited for the treatment of fiber materials, in particular of flat structures such as woven or knitted fabrics, for use in the textile sector. The textiles are given a pleasantly soft feel by the treatment with the dispersions and subsequent further processing by known methods (drying, possibly further treatment at elevated temperatures). The textiles have good sewability. The dispersions of the invention can be applied to the fiber materials in many cases using the exhaust process, but other processes, such as e.g. a foulard process, not excluded. The dispersions according to the invention have good jet mobility, so that this technology can also be used. Special effects, e.g. To achieve cellulose materials, further components can be added to the dispersions according to the invention, such as known cellulose crosslinking agents, optical brighteners and special other softening agents, such as e.g. based on reaction products of fatty acid amides with alkanolamines.

Beispiel 4 (Textilbehandlung) Example 4 (Textile Treatment)

Mit den Dispersionen, die gemäß den Beispielen 1 bis 3 erhalten worden waren, wurden Proben aus 100 % Baumwolle (Trikotware, Probengewicht ca. 20 g) in einem Ausziehverfahren bei einer Flottentemperatur von 40°C 20 Minuten lang behandelt. Die Flotten enthielten ca. 1,5 g der betreffenden Dispersion pro l Wasser. Von diesen Flotten wurden je ca. 400 ml für die Versuche verwendet. Der Ausziehgrad betrug mehr als 90 %. Nach der Behandlung wurden die Proben aus Trikotware bei 100°C 10 Minuten lang getrocknet. Anschließend wurde die Vernähbarkeit geprüft. Zur Prüfung diente das Gerät Overlock Union Spezial, Typ 39500 (Herstellerfirma: Union Spezial Lewis Columbia). Das Vernähen erfolgte mit ca. 6000 Stichen pro Minute unter Verwendung eines Langfasernähgarns aus Polyester bei einer Nahtlänge von 50 cm. Ermittelt wurde die Anzahl der Löcher an den einzelnen Trikotproben. Ergebnisse: Probenart Anzahl Löcher Beispiel 1 20 Beispiel 2 0 Beispiel 3 15 nicht ausgerüstete Trikotprobe 35 With the dispersions which had been obtained according to Examples 1 to 3, samples of 100% cotton (tricot, sample weight approx. 20 g) were treated in a pull-out process at a liquor temperature of 40 ° C. for 20 minutes. The liquors contained about 1.5 g of the dispersion in question per liter of water. About 400 ml of each of these liquors were used for the experiments. The degree of exhaustion was more than 90%. After the treatment, the tricot samples were dried at 100 ° C for 10 minutes. The sewability was then checked. The device Overlock Union Spezial, type 39500 (manufacturer: Union Spezial Lewis Columbia) was used for testing. Sewing was carried out at approx. 6000 stitches per minute using a long fiber sewing thread made of polyester with a seam length of 50 cm. The number of holes on the individual jersey samples was determined. Results: Sample type Number of holes example 1 20th Example 2 0 Example 3 15 not equipped jersey sample 35

Man erkennt, daß nicht ausgerüstete Ware mit 35 Löchern die höchste Schädigung, d.h. schlechteste Vernähbarkeit aufwies, daß die Vergleichsprobe von Beispiel 1 (Dispersion ohne Polyethylen) schlechter abschneidet als die mit erfindungsgemäßen Dispersionen behandelten Proben der Beispiele 2 und 3.It can be seen that unfinished goods with 35 holes have the highest damage, i.e. Worst sewability showed that the comparative sample of Example 1 (dispersion without polyethylene) performs worse than the samples of Examples 2 and 3 treated with dispersions according to the invention.
