Abstract

Smoothing agents in the form of an aqueous emulsion for textile fibers, composed of oxidized polyethylene, a cationic emulsifier, and a lower carboxylic acid or hydroxy carboxylic acid, and optionally, other ingredients.

Description

Eine bekannte Methode zur Verbesserung der Glätte von Textilfasermaterial ist das sogenannte Trockenparaffinieren. Hierbei wird das zu behandelnde Garn während des Spulens über festes Paraffin geführt. Der Faden nimmt durch Abrieb eine von der Art des Paraffins, vom Anpreßdruck und von der Materialgeschwindigkeit abhängige Menge Paraffin auf.A known method for improving the smoothness of textile fiber material is the so-called dry waxing. Here, the yarn to be treated is passed over solid paraffin during winding. The thread absorbs an amount of paraffin which depends on the type of paraffin, the contact pressure and the material speed.

Dieses Verfahren hat jedoch wesentliche Nachteile. So ist zur reibungslosen Weiterverarbeitung des Textilmaterials der Auftrag einer genau definierten Paraffinmenge erforderlich, wobei in Abhängigkeit von der Jahreszeit verschiedene Paraffintypen zur Anwendung kommen. Beim Spulen ist eine Herabsetzung der normalen Spulgeschwindigkeit um 20 - 25 % erforderlich. Ferner muß die Einhaltung geeigneter Temperaturen für die Lagerung der paraffinierten Spulen beachtet werden.However, this method has major disadvantages. For a smooth further processing of the textile material it is necessary to apply a precisely defined amount of paraffin, whereby different types of paraffin are used depending on the season. When winding, the normal winding speed must be reduced by 20-25%. Furthermore, the maintenance of suitable temperatures for the storage of the paraffinized coils must be observed.

Beim Verarbeiten der Garne, insbesondere von Einfachgarnen, kann es während des Paraffinierens zu Garnaufschiebungen und zu Fadenbrüchen kommen. Ein weiterer Nachteil ist das mögliche Ausblühen des Paraffins bei späteren Dämpf- und Bügelprozessen.When processing the yarns, especially single yarns, yarn postponements and thread breaks can occur during paraffining. Another disadvantage is the possible blooming of the paraffin in later steaming and ironing processes.

Weiterhin reicht die Trockenparaffinierung im allgemeinen nicht aus, um dem Material auch einen guten Griff zu verleihen. Hierzu ist die zusätzliche Behandlung mit einem üblichen kationischen Avivagemittel erforderlich.Furthermore, dry waxing is generally not sufficient to give the material a good grip. This requires additional treatment with a conventional cationic softening agent.

Die DE-A-26 21 881 beschreibt Mittel auf der Basis wässriger Paraffindispersionen, die zur Behandlung der verschiedensten Textilfasermaterialien, wie Cellulose-, Woll-, Synthesefasermaterial oder Gemischen derselben geeignet sind und diesem Material die für die Weiterverarbeitung erforderliche Glätte sowie einen guten Griff verleihen. Die Praxis hat jedoch gezeigt daß mit Naßparaffinierungsmitteln nach Art der in der DE-A-26 21 881 beschriebenen Mittel Garne aus Baumwolle oder aus Baumwolle/Synthetikfasern nicht immer ohne zusätzliche Hartparaffinierung problemlos zu verarbeiten sind.DE-A-26 21 881 describes agents based on aqueous paraffin dispersions which are suitable for treating a wide variety of textile fiber materials, such as cellulose, wool, synthetic fiber material or mixtures thereof, and which give this material the smoothness required for further processing and good grip . Practice has shown, however, that wet waxing agents of the type described in DE-A-26 21 881 do not always process yarns of cotton or of cotton / synthetic fibers without additional hard waxing.

Eine weitere, wichtige Aufgabe von textilen Glättemitteln besteht darin, textilen Flächengebilden, insbesondere Wirk- und Webwaren, eine einwandfreie Vernähbarkeit zu vermitteln. Treten beim Vernähen zu hohe Reibkräfte auf, dann entstehen Nähschäden, indem Fäden angeschlagen, zerschlagen oder thermisch geschädigt werden. Die Folgen eines Nähschadens sind besonders bei Maschenware folgenschwer, weil spätestens bei mechanischer Beanspruchung der Ware Fallmaschen entstehen. Insofern ist auch die Beweglichkeit der Fäden im Maschenve,rband von wesentlicher Bedeutung. Die Reduzierung der Nadeleinstichkräfte beim Nähen auf modernen Schnellnähern hat besondere Bedeutung gewonnen, da letztere rein mechanisch bis 7.000 Einstiche/ min leisten können. Hierzu sind jedoch dickere - weil schwingungsstabilere - Nadeln erforderlich, die wiederum leichter Maschenschäden verursachen.Another important task of textile smoothing agents is to impart perfect sewability to textile fabrics, in particular knitted and woven goods. If friction forces are too high when sewing, sewing damage will occur if threads are struck, broken or thermally damaged. The consequences of sewing damage are particularly serious in the case of knitwear, because drop stitches occur at the latest when the goods are mechanically stressed. In this respect, the mobility of the threads in the mesh belt is also of essential importance. The reduction of the needle insertion forces when sewing on modern high-speed sewers has gained particular importance, since the latter can achieve up to 7,000 stitches / min purely mechanically. For this, however, thicker needles - because they are more vibration-stable - are required, which in turn cause more stitch damage.

Aufgabe der Erfindung ist daher die Entwicklung von Glättemitteln in Form wäßriger Dispersionen, die zur Behandlung der verschiedensten Textilfasermaterialien, wie Cellulose-, Woll-, Synthesefasermaterial, oder von Gemischen derselben geeignet sind. Insbesondere ist es das Ziel der Erfindung, Garne aus Baumwolle oder Baumwoll-Synthesefaser-Mischungen so auszurüsten, daß sie ohne zusätzliche Hartparaffinierung auch unter ungünstigen Praxisbedingungen zu Maschenware zu verarbeiten sind, bzw. daß daraus hergestellte textile Flächengebilde, vorzugsweise Wirk- und Webwaren, auch auf modernen Schnellnähmaschinen keine Nähschäden erleiden.The object of the invention is therefore the development of smoothing agents in the form of aqueous dispersions which are suitable for treating a wide variety of textile fiber materials, such as cellulose, wool, synthetic fiber material, or mixtures thereof. In particular, it is the object of the invention to equip yarns made of cotton or cotton-synthetic fiber blends in such a way that they can be processed into knitwear without additional hard waxing, even under unfavorable practical conditions, or that textile fabrics, preferably knitted and woven goods, are made from them Do not suffer sewing damage on modern high-speed sewing machines.

The textile fiber materials are in the form of flakes, slats, yarn, knitted fabrics, fabrics or nonwovens, preferably yarn, knitted fabrics and fabrics. The material can be raw white, bleached or colored.

Die Applikation der Glättemittel kann in üblichen Apparaturen, wie Färbeapparaturen für Kreuzspulen, Strang oder Muffs, auf der Haspelkufe oder auf Jetfärbeanlagen erfolgen. Vorzugsweise wird im Ausziehverfahren aus wäßriger Flotte bei einem Flottenverhältnis von 1 : 8 bis 1 : 40 und einem Flotten-pH von 2 - 8, bei 25 - 80°C gearbeitet, wobei die Konzentration 0,2 - 3,0, vorzugsweise 0,2-2,5 Gew.-% an Glättemittelwirkstoff, bezogen auf das Warengewicht, beträgt. Die Ausrüstung kann in Gegenwart von Elektrolyten, wie Na-Acetat, Na-Sulfat, Na-chlorid etc. erfolgen.The smoothing agents can be applied in customary equipment, such as dyeing equipment for packages, strands or muffs, on the reel runner or on jet dyeing equipment.

The finishing can take place in the presence of electrolytes, such as Na acetate, Na sulfate, Na chloride etc.

Die Glättemittel können auch in einem sog. Zwangsapplikations erfahren, wie z. B. im Foulard oder in der Lisseuse, auf das Textilmaterial gebracht werden. Im Foulardverfahren wird mit einer Konzentration von 2 - 10 g/1, vorzugsweise 4 - 7 g/I, berechnet auf 100 % Wirkstoffgehalt, gearbeitet, wobei auch gleichzeitig Hochveredelungsmittel, wie Knitterarm-oder Krumpffest-Ausrüstungsmittel eingesetzt werden können.The smoothing agents can also be experienced in a so-called forced application, such as. B. in the foulard or in the lisseuse, brought to the textile material. The padding process is carried out at a concentration of 2-10 g / 1, preferably 4-7 g / I, calculated on 100% active ingredient content, it also being possible to use high-quality finishing agents, such as anti-crease or anti-shrinkage finishing agents.

Die erfindungsgemäß ausgerüsteten Textilmaterialien zeigen einen weichen, geschmeidig-eleganten Griff, weshalb eine zusätzliche Applikation von Avivagemitteln nicht erforderlicht ist.The textile materials equipped according to the invention have a soft, supple and elegant handle, which is why an additional application of finishing agents is not necessary.

Die Glättewerte (Reibwerte) liegen im Vergleich zu anderen bekannten Naßparaffinierungsmitteln, insbesondere bei Baumwolle und Baumwoll-Mischungen, deutlich niedriger und weisen eine hohe Gleichmäßigkeit auf, wodurch eine einwandfreie Verarbeitung zu Maschenware (beim Stricken und Wirken) möglich ist. Dieser Effekt tritt insbesondere unter praxisüblichen Trocknungsbedingungen ein. Eine zusätzliche Hartparaffinierung entfällt. Die erfindungsgemäß hergestellten Gestricke und Gewirke zeigen gute und ruhige Maschenbilder.The smoothness values (coefficients of friction) are significantly lower in comparison to other known wet waxing agents, in particular in the case of cotton and cotton blends, and have a high degree of uniformity, which enables perfect processing into knitted fabrics (for knitting and knitting). This effect occurs especially under normal drying conditions. There is no additional hard waxing. The knitted fabrics and knitted fabrics produced according to the invention show good and calm stitch patterns.

Die Nadeleinstichkräfte von Web- und Wirkwaren weisen ungewöhnlich niedrige Werte auf. Dies gilt sowohl für ausschließlich mit den erfindungsgemäßen Glättemitteln behandelte Ware wie auch für solche Ware, die mit einer praxisüblichen Kunstharzappretur ausgerüstet ist.The needle penetration forces of woven and knitted goods show unusually low values. This applies both to goods treated exclusively with the smoothing agents according to the invention and to goods which are equipped with a customary synthetic resin finish.

Die Substantivität der Glättemittel ist sehr gut und führt zu hoher Flottenausbeute. Die Thermostabilität der Glättemittel ist sehr hoch, so daß es bei den üblichen Trocknungaprozessen weder zur Rauchentwicklung noch zu Abscheidungen im Trockner kommt.The substantivity of the smoothing agents is very good and leads to a high liquor yield. The thermal stability of the smoothing agent is very high, so that in the usual drying processes neither smoke nor deposits in the dryer occur.
