Description

Um gefärbte oder ungefärbte Stapelfasergarne für das Stricken einsetzen zu können, ist es üblich, diese während eines Umspulprozesses mit einem festen Paraffinblock zu behandeln. Dabei wird auf die Faser eine bestimmte Menge festen Paraffins aufgebracht und erhält den für den Weiterverarbeitungsprozess nötigen niedrigen Reibungskoeffizienten, d.h. eine hohe Glätte. Es ist verständlich, dass dieser Vorgang des sogenannten Trockenparaffinierens in der Praxis nicht unproblematisch ist. Je nach Druck zwischen Faser und Paraffinblock kann die Auflage an Trokkenparaffin schwanken. Das feste Paraffin kann in nachfolgenden Erhitzungsprozessen (Bügeln, Fixieren) wegsublimieren und damit zum Ausblühen neigen. Das starre Trockenparaffin verleiht dem Material zwar eine ausreichende Glätte für die Weiterverarbeitung, ein eigentlicher Weichmachungseffekt ist mit seiner Applikation jedoch nicht verbunden. Damit besteht für trockenparaffinierte Artikel die Notwendigkeit, in einer nachträglichen Arbeitsstufe diese Artikel durch Aufbringen eines zusätzlichen Weichmachers noch weichzumachen.In order to be able to use dyed or undyed staple fiber yarns for knitting, it is common to treat them with a solid paraffin block during a rewinding process. A certain amount of solid paraffin is applied to the fiber and receives the low coefficient of friction required for the further processing process, i.e. a high smoothness. It is understandable that this process of so-called dry waxing is not without problems in practice. Depending on the pressure between the fiber and the paraffin block, the layer of dry paraffin may fluctuate. The solid paraffin can sublime away in subsequent heating processes (ironing, fixing) and thus tend to bloom. The rigid dry paraffin gives the material sufficient smoothness for further processing, but there is no actual softening effect associated with its application. There is therefore a need for dry-waxed articles to soften these articles in a subsequent work step by applying an additional plasticizer.

Damit stellt sich die Aufgabe Stapelfasergarnen eine für die Weiterverarbeitung nötige gleichmässige niedrige Reibung, d.h. hohe Glätte in Verbindung mit zufriedenstellender Weichheit zu geben. Das Problem kann dadurch gelöst werden, dass ein Mittel zur Nassparaffinierung von Garnen folgender Zusammensetzung eingesetzt wird:

  • a) 18-40% Paraffin, Schmelzbereich 45-60°C;
  • b) 2-8% eines oder mehrerer Alkylimidazoline der Formel
    Figure imgb0001
    wobei R C12-C22-Alkyl, Alkenyl oder Hydroxialkyl, R1 H, C1-C22-aliphatisches oder aromatisches Acyl, R2 H, C1-C4-Alkyl oder Hydroxialkyl, n Zahlen von 2 bis 6 und X ein Halogen-, C1-C4-Alkylsulfat-, C1-C4-Dialkylphosphat- oder C1-C4-AI- kylcarboxylat-anion bedeuten;
  • c) 1-7% eines oder mehrerer Aminoxide der allgemeinen Formel II
    Figure imgb0002
    wobei R C8-C12-Alkyl- oder Alkenyl, R1 C1-C4-Alkyl, R2 H oder C1-C4-Alkyl und n Zahlen von Null bis 6 bedeuten;
  • d) 2-9% eines Ethylenoxid/Propylenoxid-Blockpolymerisats der Formel III
    Figure imgb0003
    wobei x Zahlen von 20-40 und y Zahlen von 25 bis 1000 sein können;
  • e) 0-5% eines Polyglykolethers der Formel IV
    Figure imgb0004
    wobei R C8-C18 Alkyl- oder Alkenyl und n Zahlen von 3-12 sind sowie
  • f) 0-2% eines Copolymeren aus Vinylpyrrolidon und Vinylacetat, wobei das Gewichtsverhältnis VP/VAc von 3:7 bis 8:2 variieren kann und der an 100 Gew.-% fehlende Rest ist Wasser.
The task thus arises of giving staple fiber yarns a uniformly low friction required for further processing, ie high smoothness combined with satisfactory softness. The problem can be solved by using a wet waxing agent for yarns of the following composition:
  • a) 18-40% paraffin, melting range 45-60 ° C;
  • b) 2-8% of one or more alkylimidazolines of the formula
    Figure imgb0001
     where RC 12 -C 22 alkyl, alkenyl or hydroxyalkyl, R 1 H, C 1 -C 22 aliphatic or aromatic acyl, R 2 H, C 1 -C 4 alkyl or hydroxyalkyl, n numbers from 2 to 6 and X is a halogen, C 1 -C 4 alkyl sulfate, C 1 -C 4 dialkyl phosphate or C 1 -C 4 alkyl carboxylate anion;
  • c) 1-7% of one or more amine oxides of the general formula II
    Figure imgb0002
     wherein RC 8 -C 12 alkyl or alkenyl, R 1 C 1 -C 4 alkyl, R 2 H or C 1 -C 4 alkyl and n are numbers from zero to 6;
  • d) 2-9% of an ethylene oxide / propylene oxide block polymer of the formula III
    Figure imgb0003
     where x can be numbers from 20-40 and y can be numbers from 25 to 1000;
  • e) 0-5% of a polyglycol ether of the formula IV
    Figure imgb0004
     where RC 8 -C 18 alkyl or alkenyl and n are numbers from 3-12 and
  • f) 0-2% of a copolymer of vinylpyrrolidone and vinyl acetate, the weight ratio VP / VAc can vary from 3: 7 to 8: 2 and the remainder missing in 100% by weight is water.

Vorzugsweise wird ein Mittel folgender Zusammensetzung verwendet:

  • 20-30% Paraffin (Fp. 50-53 °C)
  • 3-6% eines Imidazolins der Formel I, wobei R C12-C18-Alkyl, R1 C16-C22-Acyl, R2 Wasserstoff, X⊖ Cl⊖ oder CH3COO⊖ und n 2 oder 3 bedeutet;

  • 2-6% eines Blockpolymerisats der Formel III, wobei x eine Zahl von 25-40 und y eine Zahl von 100-900 ist mit einem Molgewicht >8000;
  • 0-2% eines Polyglykoläthers der Formel IV, wobei R C12-C18-Alkyl und Alkenyl (Cocosalkyl) und n n Zahlen von 4-8 bedeuten
  • und der an 100 Gew.-% fehlende Rest ist Wasser.
An agent of the following composition is preferably used:
  • 20-30% paraffin (mp. 50-53 ° C)
  • 3-6% of an imidazoline of the formula I, where RC 12 -C 18 alkyl, R 1 C 16 -C 22 acyl, R 2 is hydrogen, X⊖ Cl⊖ or CH 3 COO⊖ and n is 2 or 3;
  • 2-6% of an amine oxide of the formula II, where RC 8 -C 18 alkyl or alkenyl, R 1 and R 2 are methyl and n is zero;
  • 2-6% of a block polymer of the formula III, where x is a number from 25-40 and y is a number from 100-900 with a molecular weight>8000;
  • 0-2% of a polyglycol ether of the formula IV, where RC 12 -C 18 alkyl and alkenyl (cocoalkyl) and nn are numbers from 4-8
  • and the remainder missing in 100% by weight is water.

Die Herstellung der Paraffindispersion erfolgt durch intensives Mischen aller Komponenten mit einem Homogenisator. Man kann dabei jeweils nur eine der mit a) bis f) gekennzeichneten Komponenten verwenden, es ist aber ebenso möglich, Gemische dieser Einzelkomponenten a) - f) einzusetzen. Diese Paraffindispersionen, die beim Verdünnen mit Wasser lager- und scherstabile Feindispersionen bilden, können anstelle von festem Trockenparaffin zum Paraffinieren von Stapelfasergarnen aus nativen und synthetischen Fasern eingesetzt werden. Sie können als pseudokationisch dispergierte Systeme bezeichnet werden und zeichnen sich durch hohe Substantivität beim Einsatz in langer Flotte aus. Der pH-Wert der Paraffindispersionen liegt beim Einsatz vorteilhaft bei 3-6 und wird mit Säuren auf diesen Wert eingestellt.The paraffin dispersion is prepared by intensively mixing all components with a homogenizer. You can only use one of the components labeled a) to f), but it is also possible to use mixtures of these individual components a) - f). These paraffin dispersions, which form fine dispersions that are stable in storage and shear when diluted with water, can be used instead of solid dry paraffin for the paraffin waxing of staple fiber yarns from native and synthetic fibers. They can be called pseudo-cationically dispersed systems and are characterized by high substantivity when used in a long fleet. The pH value of the paraffin dispersions is advantageously 3-6 when used and is adjusted to this value with acids.

Die Applikation der Paraffindispersionen erfolgt in üblichen Färbeapparaten, wie sie zum Färben von Textilgarnen verwendet werden. Gearbeitet wird dabei in Flottenverhältnissen von 1:5 bis 1:40 bei Temperaturen von 10-90°C. Vorteilhaft erfolgt die Applikation nach dem Färbeprozess, in dem nach dem Spülen das Garn mit einer Dispersion der oben beschriebenen Art in verdünnter wässriger Form behandelt, die 0,1-2 Gew.-%, vorzugsweise 0,3-1 Gew.-% der oben beschriebenen Komponenten a) bis f), bezogen auf das Garngewicht, enthält.The paraffin dispersions are applied in customary dyeing machines such as those used for dyeing textile yarns. We work in liquor ratios from 1: 5 to 1:40 at temperatures of 10-90 ° C. Application is advantageously carried out after the dyeing process, in which, after rinsing, the yarn is treated with a dispersion of the type described above in dilute aqueous form, 0.1-2 % By weight, preferably 0.3-1% by weight, of components a) to f) described above, based on the weight of the yarn.

Die auf diese Weise paraffinierten Garne zeigen neben der gewünschten Glätte einen angenehmen weichen Griff, der die Applikation eines zusätzlichen Weichmachers überflüssig macht. Durch die in den Systemen eingebauten Dispergiermittel kommt es zu keiner das Stricken störenden elektrostatischen Aufladung. Die erfindungsgemässen Paraffindispersionen enthalten auch keine organischen Solventien, die für die Umwelt, besonders beim Arbeiten in offenen Apparaten, schädlich sein könnten. Sie enthalten als Gleitkomponente lediglich das wohlfeile Paraffin und benötigen für die Glättevermittlung und den Weichmachungseffekt keine zusätzlichen Komponenten, wie z.B. Fettsäureester, die im Vergleich zu Paraffin teuer sind. Die erfindungsgemässen Paraffindispersionen zeigen eine hohe Substantivität, verbunden mit einer hohen Netzkraft, die die Applikation auch in kurzen Versuchszeiten und bei niederer Temperatur ermöglicht.In addition to the desired smoothness, the yarns paraffinized in this way have a pleasantly soft feel, which makes the application of an additional plasticizer unnecessary. Due to the dispersing agents built into the systems, there is no electrostatic charge disturbing knitting. The paraffin dispersions according to the invention also do not contain any organic solvents which could be harmful to the environment, especially when working in open apparatus. They only contain the inexpensive paraffin as a sliding component and do not require any additional components for conveying smoothness and the softening effect, e.g. Fatty acid esters, which are expensive compared to paraffin. The paraffin dispersions according to the invention have a high substantivity, combined with a high wetting power, which enables application even in short test times and at a low temperature.
