Definitions
- polyoxyalkylene glycols which evaporate residue-free when heat-treated synthetic fibers such as texturing, so that when used in fiber preparation agents, the cleaning intervals of the texturing devices used are relatively long in time apart.
- end-capped polyoxyalkylene glycols are known from EP-B-162 530, which have good properties as fiber preparation agents and are also distinguished by low residue formation on the fiber after heating processes.
- biodegradable is to be understood to mean that the constituents of fiber preparation agents, such as lubricants, surfactants, thread-closing agents or also antistatic agents, are completely or at least 70% by weight by biological means, for example by the enzymes or contained in the sewage sludge of a sewage treatment plant Bacteria are broken down.
- Preferred constituents of these biodegradable fiber preparation agents are compounds of the formula I in which R is a 1-methylpropylene radical, 2-methylpropylene radical or a 2,2-dimethylpropylene radical, particularly preferably a 1-methylethylene radical (isopropylene radical).
- the compounds of the formula I are well suited as fiber preparation agents.
- the compounds of formula I are generally water-soluble or water-dispersible. They can be used as fiber preparation agents either alone or as a mixture with one another or with others known per se Fiber preparation agents such as surfactants, antistatic agents, such as P2O5 ester salts, lubricants, such as ester oils or thread-locking agents, such as ethoxylated castor oils, which must also be biodegradable.
- the proportion of the compounds of the formula I should be in the range from 10 to 100 parts by weight, based on the fiber preparation agent.
- the coating should be 0.1 to 1% by weight, preferably 0.3 to 0.5% by weight, based on the weight of the fiber, the Compounds of formula I are contained in the fiber preparation agent according to the percentages given above.
- the fiber preparation agents can be applied from aqueous solution, dispersion or emulsion, optionally with the use of suitable solvents or dispersing agents. Since most of the compounds of formula I are readily water-soluble, in contrast to mineral or ester oils, no additional emulsifiers are required when applied to the fiber.
- the application is carried out according to the usual methods, for example by splashing, dipping, spraying, padding or gear pumps.
- Suitable synthetic fibers for which the fiber preparation agents are to be used are, for example, fibers made of polyesters, polyamides, polyacrylonitrile, polyolefins or the copolymers of the abovementioned compounds.

Abstract
Description
- Aus US-A-4 179 544 und US-A-4 227 390 sind Polyoxyalkylenglykole bekannt, die bei einer Wärmebehandlung von präparierten Synthesefasern, wie dem Texturieren, rückstandslos verdampfen, so daß bei deren Verwendung in Faserpräparationsmitteln die Reinigungsintervalle der eingesetzten Texuriereinrichtungen zeitlich relativ lange auseinander liegen. Aus EP-B-162 530 sind sogenannte endverschlossene Polyoxyalkylenglykole bekannt, die gute Eigenschaften als Faserpräparationsmittel besitzen und sich ebenfalls durch geringe Rückstandsbildung auf der Faser nach Erhitzungsprozessen auszeichnen.
- Alle diese Verbindungen zeigen jedoch den erheblichen Nachteil, daß sie biologisch nur mäßig abbaubar sind. In den letzten Jahren werden an Faserpräparationsmittel zusätzliche Bedingungen dahingehend gestellt, daß diese Mittel im Abwasser biologisch gut abbaubar sein sollen. Diese Bedingungen zielen darauf ab, die in die Abwässer von Textilbetrieben beim Färben oder Vorbehandeln gelangenden Faserpräparationsmittel durch biologischen Abbau zu eliminieren. Unter dem Begriff "biologisch abbaubar" ist zu verstehen, daß die Bestandteile von Faserpräparationsmitteln, wie Gleitmittel, Tenside, Fadenschlußmittel oder auch Antistatika vollständig oder zumindest zu 70 Gew.-% auf biologischem Weg, z.B. durch die in dem Klärschlamm einer Kläranlage enthaltenen Enzyme oder Bakterien, abgebaut werden. Dabei ist es wünschenswert, daß bei dem Abbau chemisch einfache Verbindungen, wie Kohlendioxid, Wasser, Sulfat oder Phosphat, entstehen.
Um die biologische Abbaubarkeit von chemischen Verbindungen beurteilen zu können, wurden eine Reihe von Testverfahren erarbeitet. Als geeignetes Verfahren zur Überprüfung der biologischen Abbaubarkeit von Faserpräparationsmitteln wird der "Coupled-Units-Test" (OECD-303-A-Test) genannt. - Die Bereitstellung biologisch abbaubarer Faserpräparationsmittel bereitet nach wie vor große Schwierigkeiten. Hier will die Erfindung Abhilfe schaffen.
- Gegenstand der Erfindung sind Faserpräparationsmittel, gekennzeichnet durch einen Gehalt an Verbindungen der allgemeinen Formel
HO(CH₂CH₂O)x-RO-(CH₂CH₂O)yH I
worin - R
- für einen einfach oder mehrfach alkylsubstituierten Alkylenrest mit 2 bis 4 Kohlenstoffatomen in der Alkylenkette und mit Methyl, Ethyl, Propyl oder Isopropyl als Alkylsubstituent steht und
die Summe von x und y 10 bis 20 beträgt, wobei x und y verschieden von Null sind. - Bevorzugte Bestandteile dieser biologisch abbaubaren Faserpräparationsmittel sind Verbindungen der Formel I, in denen R ein 1-Methylpropylenrest, 2-Methylpropylenrest oder ein 2,2-Dimethylpropylenrest, besonders bevorzugt ein 1-Methylethylenrest (Isopropylenrest), ist.
- Die Herstellung dieser Verbindungen der Formel I erfolgt nach dem in der EP-B-166 958 beschriebenen Verfahren, indem ein Glykol mit Ethylenoxid umgesetzt wird.
- Infolge ihrer unerwartet geringen Rückstandsbildung bei Erhitzungsprozessen, wie dem Texturieren, und ihrer überraschend guten biologischen Abbaubarkeit, eignen sich die Verbindungen der Formel I gut als Faserpräparationsmittel. Die Verbindungen der Formel I sind im allgemeinen wasserlöslich oder in Wasser dispergierbar. Sie können als Faserpräparationsmittel sowohl allein als auch in Mischung untereinander oder mit anderen an sich bekannten Faserpräparationsmitteln wie Tensiden, Antistatika, wie P₂O₅-Estersalzen, Gleitmitteln, wie Esterölen oder Fadenschlußmitteln, wie ethoxylierten Rizinusölen angewendet werden, die ebenfalls biologisch abbaubar sein müssen.
- Bei Verwendung einer Mischung der Verbindungen der Formel I mit bekannten Faserpräparationsmitteln soll der Anteil der Verbindungen der Formel I im Bereich von 10 bis 100 Gew.-Teilen, bezogen auf das Faserpräparationsmittel liegen. Bei der Präparation von Synthesefasern mit den Verbindungen der Formel I oder deren Mischungen soll die Auflage 0,1 bis 1 Gew.-%, bevorzugt 0,3 bis 0,5 Gew.-%, bezogen auf das Gewicht der Faser betragen, wobei die Verbindungen der Formel I entsprechend den vorstehend prozentualen Angaben in dem Faserpräparationsmittel enthalten sind.
- Die Faserpräparationsmittel können aus wäßriger Lösung, Dispersion oder Emulsion, gegebenenfalls unter Mitverwendung geeigneter Löse- oder Dispergiermittel, aufgebracht werden.
Da die meisten Verbindungen der Formel I gut wasserlöslich sind, bedarf es bei dem Aufbringen auf die Faser, im Gegensatz zum Mineral oder Esterölen, keiner zusätzlichen Emulgatoren. - Das Aufbringen erfolgt nach den üblichen Methoden beispielsweise durch Pflatschen, Tauchen, Sprühen, Foulardieren oder Zahnradpumpen.
- Als Synthesefasern, für die die Faserpräparationsmittel anzuwenden sind, kommen z.B. Fasern aus Polyestern, Polyamiden, Polyacrylnitril, Polyolefinen oder den Copolymeren der vorstehend genannten Verbindungen in Betracht.
- Allgemeine Vorschrift zur Herstellung der nachfolgend genannten Acetale:
In einem mit Rührer umgestalteten Reaktionsgefäß werden die Menge von Glykol und alkalischem Katalysator vorgelegt. Nach Spülen mit Stickstoff zur Entfernung des Sauerstoffs wird auf 120 bis 125°C erhitzt und bei dieser Temperatur unter Rühren 2 h lang unter Wasserstrahlvakuum gehalten. Nach Wegnahme des Wasserstrahlvakuums wird unter Rühren auf 130 bis 140°C erhitzt, worauf bei dieser Temperatur in einer Zeit von etwa 3 h die erforderliche Menge gasförmiges Ethylenoxid zudosiert wird. Das Ende der Ethylenoxid-Zugabe wird am abfallenden und im wesentlichen konstant bleibende Druck erkennbar. Zur Reinigung des Reaktionsproduktes von gegebenenfalls anwesenden flüchtigen Anteilen wird dieses eine halbe Stunde lang unter Rühren bei etwa 80°C und einem Vakuum von 2 kPa gehalten. - In der nachstehenden Tabelle I sind die vorgelegten Glykole und alkalischen Katalysatoren sowie die bei der Reaktionstemperatur und dem Reaktionsdruck zudosierte Ethylenoxid-Menge zusammengefaßt.
