Abstract

Mixtures which contain oxidized polyethylenes and selected quaternary ammonium phosphates are used as textile drawing aids for rendering polyester-containing fiber materials antistatic, smooth and/or soft.

Description

Die Erfindung betrifft Mischungen, die anoxidierte Polyethylene und ausgewählte quartäre Ammoniumphosphate enthalten, sowie die Verwendung dieser Mischungen als ziehfähige Textilhilfsmittel zum Antistatisch-, Glatt- und/oder Weichmachen polyesterhaltiger Fasermaterialien.The invention relates to mixtures which contain oxidized polyethylenes and selected quaternary ammonium phosphates, and to the use of these mixtures as drawable textile auxiliaries for the antistatic, smooth and / or plasticizing of polyester-containing fiber materials.

Die Aviverung ist ein Teil der Textilveredlung und soll der Flocke, dem Kammzug, Gewebe, Gewirke oder Nonwovens insbesondere solche Eigenschaften wie Griff, Glätte, Antistatik und Fülle verleihen, durch die Aussehen, Verkaufsfähigkeit, Gebrauchstüchtigkeit und Verarbeitungseigenschaften erhöht werden. Die zur Avivierung verwendeten Textilhilfsmittel können beispielsweise auf Textilfasermaterialien im Vollbad (Ausziehverfahren) appliziert werden. Bei der Vollbadbehandlung werden die Textilien im großen Flottenverhältnis eine längere Zeit benetzt und anschließend durch Abquetschen, Absaugen oder Zentrifugieren entwässert. Im Vergleich zu anderen Behandlungsverfahren wie Foulardieren, Pflatschen, Rakeln, Besprühen, hat die Vollbadbehandlung den Vorteil, daß die Behandlungszeiten und -temperaturen beliebig gewählt und variiert werden können (siehe beispielsweise W. Bernard: "Appretur der Textilien", 2. Auflage, Seite 257-258, Springer-Verlag 1967).The Aviverung is part of the textile finishing and should give the flake, the sliver, woven fabric, knitted fabric or nonwoven in particular such properties as feel, smoothness, antistatic and fullness, through which the appearance, saleability, fitness for purpose and processing properties are increased. The textile auxiliaries used for finishing can, for example, be applied to textile fiber materials in a full bath (exhaust process). In the full bath treatment, the textiles are wetted for a long time in a large liquor ratio and then dewatered by squeezing, suctioning or centrifuging. Compared to other treatment methods such as padding, splashing, knife coating, spraying, the full bath treatment has the advantage that the treatment times and temperatures can be chosen and varied as desired (see, for example, W. Bernard: "Textile finishing", 2nd edition, page 257-258, Springer-Verlag 1967).

Das Ausziehverfahren ist jedoch nur dann wirtschaftlich, wenn Textilhilfsmittel zum Einsatz gelangen, die eine genügend hohe Substantivität zu Fasermaterialien aufweisen und damit eine gute Erschöpfung der Behandlungsflotten ermöglichen. Kationische Textilhilfsmittel, die Fasermaterialien antistatische und/oder weichmachende Eigenschaften verleihen, zeigen gegenüber natürlichen Fasern, beispielsweise Cellulose, Baumwolle und/oder Wolle eine hohe Substantivität, während die Affinität zu den meisten synthetischen Fasermaterialien, insbesondere Polyesterfasern, deutlich geringer ist (Chwala/Anger: "Handbuch der Textilhilfsmittel", Seiten 689-692, Verlag Chemie Weinheim 1967).However, the pull-out process is only economical if textile auxiliaries are used that have a sufficiently high substantivity to fiber materials and thus allow the treatment liquors to be well exhausted. Cationic textile auxiliaries which impart fiber materials with antistatic and / or softening properties show a high substantivity towards natural fibers, e.g. cellulose, cotton and / or wool, while the affinity for most synthetic fiber materials, especially polyester fibers, is significantly lower (Chwala / Anger: "Handbook of Textile Aids", pages 689-692, Verlag Chemie Weinheim 1967).

Üblicherweise werden Fett-Polyamin-Kondensationsprodukte, Fettsäureamidderivate, Paraffinemulsionen sowie Silikonderivate als Antistatika, Glättemittel und/oder Weichmacher im Ausziehverfahren verwendet. Nachteilig ist jedoch, daß diese Substanzen nur eine ungenügende Substantivität gegenüber polyesterhaltigen Fasermaterialien besitzen. Ferner weisen polyesterhaltige Fasermaterialien nach der Avivierung mit diesen bekannten Substanzen keine oder nur unbefriedigende Antistatik, Glätte und/oder Weichheit auf.Fat-polyamine condensation products, fatty acid amide derivatives, paraffin emulsions and silicone derivatives are usually used as antistatic agents, smoothing agents and / or plasticizers in the exhaust process. However, it is disadvantageous that these substances have an insufficient substantivity towards polyester-containing fiber materials. In addition, polyester-containing fiber materials have no or only unsatisfactory antistatic properties, smoothness and / or softness after finishing with these known substances.

Die der Erfindung zugrunde liegende Aufgabe bestand daher in der Entwicklung von Textilhilfsmitteln, die eine hohe Substantivität zu polyesterhaltigen Fasermaterialien besitzen und die diesen Fasermaterialien ausgezeichnete antistatische glatt- und/oder weichmachende Eigenschaften verleihen.The object on which the invention is based was therefore to develop textile auxiliaries which have a high substantivity to polyester-containing fiber materials and which give these fiber materials excellent antistatic smoothing and / or softening properties.

Es wurde gefunden, daß Mischungen, die anoxidierte Polyethylene und bestimmte quartäre Ammoniumphosphate enthalten, eine hohe Affinität zu polyesterhaltigen Fasermaterialien haben.It has been found that blends containing oxidized polyethylenes and certain quaternary ammonium phosphates have a high affinity for polyester-containing fiber materials.

Durch Kombination bestimmter quartärer Ammoniumphosphate (Komponente (B) 1 - 3) mit anoxidierten Polyethylenen (Komponente A) wird nun überraschenderweise sowohl die antistatische Wirkung als auch die Glätte polyesterhaltiger Fasermaterialien deutlich verbessert. Des weiteren verleihen die erfindungsgemäßen Mischungen polyesterhaltigen Fasermaterialien ein gutes Griffgefühl.By combining certain quaternary ammonium phosphates (component (B) 1-3) with anoxidized polyethylene (component A), both the antistatic effect and the smoothness of polyester-containing fiber materials are now surprisingly improved. Furthermore, the mixtures according to the invention give polyester-containing fiber materials a good feel.

The molar ratio of carboxylic acid: diamine is preferably between 1: 1 and 1: 2.

Zur Herstellung der Imidazoline können die Carbonsäuren sowohl einzeln als auch im Gemisch eingesetzt werden. Von besonderer Bedeutung ist der Einsatz von Fettsäuregemischen, wie sie bei der Spaltung natürlich vorkommender Fette und/oder Öle anfallen.
