Description

Es ist bekannt, Stapelfasern im trockenen oder geschmälzten Zustand mit pulverigen, amorphen oder erdigen trockenen Stoffen zu behändem, um die Haftfähigkeit der FaseroberfJäche und dadurch die Spinnfähigkeit der Fasern zu erhöhen. Der Umgang mit den trockenen feinteiligen Stoffen im Verarbeitungsbetrieb ist sehr lästig. Zudem muß das so behandelte Fasermaterial vor dem Spinnen entstaubt und gegebenenfalls noch einmal geschmälzt werden. Auch die als möglich empfohlene gleichzeitige Anwendung von pulverförmigen Stoffen und daneben z. B. Seifen oder Ölen, wodurch das Haften der pulverförmigen Stoffe auf der Faser verbessert und deren Aufnahmefähigkeit für die Seifen oder Öle erhöht werden soll, ist im Verarbeitungsbetrieb schwer durchführbar. Ein ähnlich umständliches Verfahren besteht darin, daß man Fasern mit Metallsalzlösungen tränkt und darauf durch Behandeln mit Fällungsmitteln auf den Fasern Niederschläge fester Partikeln erzeugt. Außer diesen auf das Sekundärspinnen gerichteten Maßnahmen kennt man das Einmischen von Kieselsäureaerogelen in Spinnlösungen, also vor dem Primärspinnen; Fasern von erhöhter Scheuer- und Aufspleißfestigkeit sollen auf diese Weise erzeugt werden. Es ist ferner bekannt, daß man natürliche und chemische Fasern in ihren Spinneigenschaften dadurch wesentlich verbessern kann, daß man wäßrige Dispersionen oder kolloide Lösungen der Kieselsäure für sich oder in Verbindung mit anderen Metalloxyden den vor dem Verspinnen auf die Fasern zu bringenden Präparations- oder Avivagemitteln oder Schmälzemulsionen zugibt. Dieses Verfahren hat aber den Nachteil, daß die Dispersionen und Sole der Kieselsäure gewöhnlich nur einen sehr geringen SiO2-Gehalt aufweisen^ so daß gleichzeitig mit den wirksamen Substanzen große Wassermengen transportiert werden müssen.It is known to handle staple fibers in the dry or melted state with powdery, amorphous or earthy dry substances in order to increase the adhesiveness of the fiber surface and thus the spinnability of the fibers. Handling the dry, finely divided substances in the processing plant is very annoying. In addition, the fiber material treated in this way must be dedusted before spinning and, if necessary, melted again. The simultaneous use of powdered substances and, in addition, z. B. soaps or oils, whereby the adhesion of the powdered substances to the fiber is improved and their absorption capacity for the soaps or oils is to be increased, is difficult to carry out in the processing plant. A similarly laborious process consists in soaking fibers with metal salt solutions and then producing precipitates of solid particles on the fibers by treating them with precipitants. In addition to these measures aimed at secondary spinning, the mixing of silicic acid aerogels into spinning solutions, that is to say before primary spinning, is known; Fibers of increased abrasion and splice resistance are intended to be produced in this way. It is also known that the spinning properties of natural and chemical fibers can be significantly improved by using aqueous dispersions or colloidal solutions of silicic acid, either alone or in combination with other metal oxides, with the preparation or softening agents to be applied to the fibers prior to spinning Adding lime emulsions. However, this process has the disadvantage that the dispersions and sols of the silica usually only have a very low SiO 2 content, so that large amounts of water have to be transported at the same time as the active substances.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Spinnfähigkeit und sonstige verarbeitungs- und auch anwendungstechnische Eigenschaften von natürlichen und chemischen Fasern oder ihren Gemischen zu verbessern und dafür Mittel zur Verfügung zu stellen, die sich auf technisch vorteilhafte Weise anwenden lassen.The present invention is based on the object the spinnability and other processing and application properties of natural and to improve chemical fibers or their mixtures and to make funds available for this, which are based on can be used in a technically advantageous manner.

Solche Mittel sind erfindungsgemäß Präparationsmittel, Avivagemittel und Schmälzemulsionen, deren Kennzeichen darin besteht, daß sie in fester, feinstverteilter Form als Aerogel zugesetzte Kieselsäure, Tonerde oder andere Metalloxyde oder Gemische daraus enthalten.According to the invention, such agents are preparation agents, softeners and lubricant emulsions, their characteristics consists in the fact that they are in solid, finely divided form as an airgel added silica, clay or contain other metal oxides or mixtures thereof.

Die festen feinstverteilten Zusatzstoffe werden den vor dem Verspinnen auf die Fasern zu bringenden Präparations-, Avivagemitteln oder Schmälzemulsionen zweckmäßigerweise in einer Teilchengröße von 1 bis 500 μμ einverleibt. The solid, finely divided additives are expediently incorporated in a particle size of 1 to 500 μμ into the preparation, softening agents or sizing emulsions to be applied to the fibers before spinning.

Durch das Einbringen von derartigen Aerogelen in die Präparations-, Avivagemittel oder Schmälzen werden die Haftungseigenschaften der damit behandelten natürlichen oder chemischen Fasern besonders günstig verändert. Die Präparationsmittel, AvivagemittelBy introducing such aerogels into the preparation, softening agents or lubricants, the Adhesion properties of the natural or chemical fibers treated therewith changed particularly favorably. the Preparation agents, softeners

Haftkraft bzw. Haftlänge des Faservlieses oder des Kardenoder Krempelbandes, Kammzuges oder der Flyerlunte bzw. der Vorgarne wird wesentlich erhöht. Man erzielt ein gleichmäßigeres und festeres Garn und Vorgarn, das weniger zu Fadenbrüchen neigt. Die Spinnereiproduktion wird erhöht, denn die Garne benötigen weniger Drehungen (füllige Schuß- und Trikotgarne). Ferner wird eine Verminderung des Abfalls erreicht. Eine Vergilbung der Fasern bzw. Garne tritt nicht ein.Adhesive force or adhesive length of the fiber fleece or card or Carding tape, top sliver or flyer roving or roving is significantly increased. One achieves a More even and stronger yarn and roving that are less prone to thread breaks. The spinning mill is increased because the yarns require fewer twists (full weft and tricot yarns). There is also a decrease of waste achieved. There is no yellowing of the fibers or yarns.

Bei der Baumwolle kommt eine Anwendung der Präparations- und Avivagemittel vor allem bei der Verspinnung gebleichter und gefärbter Flocke in Frage. Bei den chemischen Fasern ist ohnehin die Anwendung von Präparationsmitteln notwendig, damit die Fasern weich und offen werden. Bei den synthetischen Fasern, die oft eine zu große Weichheit aufweisen, kommt eine Kombination mit antistatischen bzw. versteifenden Präparationsmitteln in Frage.In the case of cotton, the preparation and softening agents are mainly used during spinning bleached and colored flake in question. In the case of chemical fibers, the use of Preparation agents necessary so that the fibers become soft and open. In the case of synthetic fibers, often have too great a softness, a combination with antistatic or stiffening preparation agents is used in question.
