Description

Mischkomponenteli£asern aus PolLmermischungen nach dem Schmelsspinnverfahren.Mixed components made from polymer mixtures using the melt spinning process.

Gegenstand der vorliegenden Anmeldung sind Mischkomponentenfasern aus Polyester und Polyamid mit hervorragenden textilen Eigenschaften, die insbesondere dazu geeignet sind, im Schmelzspinnverfahren aus Endlosfasern dimensionsstabile Vliese herzustellen.The present application relates to mixed component fibers made of polyester and polyamide with excellent textile properties, in particular are suitable for this, dimensionally stable in the melt spinning process from continuous fibers Manufacture nonwovens.

Es sind Fasern aus z.B. zwei diskreten Komponenten mit besonderen Düsenkonstruktionen im Schmel spinnverf ahren erzeugt worden, wobei eine Kern- und eine Mantelphase oder auch eine andere Phasenverteilung im Faserquerschnitt gebildet wird, weil beabsichtigt ist, eine Strukturierung oder einen Eräuseleffekt oder auch eine Verfestigung eines Vlieses durch Hitze und Druckeinwirkung zu erzielen.They are fibers made of e.g. two discrete components with special ones Nozzle structures have been produced in the Schmel spinnverf ahren, with a core and a cladding phase or another phase distribution is formed in the fiber cross-section is because it is intended, a structuring or a noise effect or also to achieve consolidation of a fleece through the action of heat and pressure.

Mischkomponentenfasern sind bereits bekannt, und zwar sowohl aus binären als auch aus ternären und quaternären Mischungen.Mixed component fibers are already known, both from binary as well as from ternary and quaternary mixtures.

Bekannt ist z.B. eine Nischkomponentenfaser aus 70 O/o Caprolactam und 3o % Polyäthylenterephthalat, die besonders zur Herstellung von Reifencord entwickelt und unter dem Namen "Source" vertrieben wird.For example, a niche component fiber made from 70 o / o caprolactam is known and 3o% polyethylene terephthalate, specially developed for the manufacture of tire cord and is sold under the name "Source".

Aus hierüber bekanntgewordenen Veröffentlichungen geht hervor, dass die Festigkeit der Fasern weitestgehend durch die Polyamid-Matrix bestimmt wird und dass der Polyesteranteil in Form von Mikrofibrillen vorliegt. Die Zusammensetzung soll zwischen 50 und lo % Polyester variiert werden können.It emerges from publications that have become known that the strength of the fibers is largely determined by the polyamide matrix and that the polyester portion is in the form of microfibrils. The composition should be able to vary between 50 and 10% polyester.

Demgegenüber wurde überraschenderweise gefunden, dass sich eine Mischkomponentenfaser mit grosser Gleichmässigkeit im Schmelzspinnverfahren aus einer Mischung erzeugen lässt, deren überwiegende Komponente aus Polyester besteht, z.B.In contrast, it was surprisingly found that a mixed component fiber Produce with great uniformity in the melt spinning process from a mixture leaves, the predominant component of which consists of polyester, e.g.

aus 6o % Polyester, der als fibrilläre Komponente 4o % Polyamid zugefügt ist.Made of 6o% polyester, to which 4o% polyamide is added as a fibrillar component is.

Die Mischung der getrockneten, rieselfähigen Granulate erfolgt bei Raumtemperatur in einer Stickstoffatmosphäre. Die eigentliche Homogenisierung erfolgt anschliessend in einem Einschneckenextruder unter starker Scherkrafteinwirkung in einem Temperaturbereich von etwa 26o bis 28o0C. Der sich anschliessende Spinnprozess, einschliesslich der Verstrekkung der Fäden mittels Pressluft, ist nicht Gegenstand der mmeldung.The mixing of the dried, free-flowing granules takes place at Room temperature in a nitrogen atmosphere. The actual homogenization takes place then in a single screw extruder under strong shear force in a temperature range of about 26o to 28o0C. The subsequent spinning process, including the stretching of the threads by means of compressed air is not an issue the message.

Es wurde nun weiterhin gefunden, dass sich durch Änderung der Gewichtsverhältnisse der o.g. Polyeorkomponenten, wobei sich stets die Polyesterkomponente im Gegensatz zu den bekanntgewordenen Veröffentlichungen im eberschuss befindet, das Sahrumpfverhalten der Fasern steuern lässt. Das bedeutet deshalb einen besonderen technischen und wirtschaftlichon Fortschritt, weil nunmehr ohne Änderung der technischen Vorrichtungen sich allein durch Variation des Mischungsverhältnisses das 8chrumpfverhalten der Einzelfaser zwischen o,3 % und etwa 40 % und dementsprechend auch dasjenige eines Spinnvlieses beeinflussen lässt.It has now also been found that by changing the weight ratios of the above-mentioned polyester components, whereby the polyester component is always in opposition in excess of the publications that have become known is the behavior of the Sahrumpf the fibers can be controlled. That therefore means a special technical and economicalon Progress because now without changing the technical Devices can improve their shrinkage behavior simply by varying the mixing ratio the single fiber between 0.3% and about 40% and accordingly also that can influence a spunbond.

Um das Schrumpfverhalten der Einzelfasern festzustellen, wurden sie 5 Minuten in ein Wasserband mit einer Temperatur von loo0O getaucht. Bei einem Titer von ca 6 den. bei nachstehenden Mischungsverhältnissen ergeben sich folgende Schrumpfwerte: PES/PA Schrumpfung % 60/40 o,3 70/30 o,5 80/20 4,o (siehe Diagramm) 9o/lo l9,o 95/5 4o,o loo/o 58,o Somit ist es möglich geworden, mit ein und derselben Anlage, selbstverständlich unter Auswechslung der Spinndüsen, feine und grobe Titer zu spinnen und auf diese Weise Vliese zu erzeugen, die für ganz verschiedene Weiterverarbeitungen geeignet sind, beispielsweise zur Herstellung von Bodenbelägen, bei denen reine Endlos-Polyamidfasern nicht verwendet werden können, da sie wegen der Feuchtigkeitsaufnahme zu nicht genügend maßstabilen Erzeugnissen führen. Dagegen schrumpfen reine Endlos-Polyesterfasern unter Wärmeeinwirkung stark. Erst die erfindungsgemässe modifizierte Endlos-Polyesterfaser ermöglicht es erstmals eine Faser herzustellen, welche unter Feuchtigkeits- und Wärmeeinwirkung maßstabil bleibt, was für Bodenbeläge eine wesentliche Voraussetzung ist.In order to determine the shrinkage behavior of the individual fibers, they were Immersed in a band of water with a temperature of 100O for 5 minutes. At one titer of about 6 den. with the following mixing ratios the following shrinkage values result: PES / PA shrinkage% 60/40 o, 3 70/30 o, 5 80/20 4, o (see diagram) 9o / lo l9, o 95/5 4o, o loo / o 58, o Thus it has become possible with one and the same system, of course with replacement of the spinnerets, fine and coarse titers to spin and on these Way to produce fleeces that are suitable for a wide variety of further processing are, for example, for the production of floor coverings in which pure continuous polyamide fibers cannot be used because they are too inadequate because of the moisture absorption lead dimensionally stable products. Against it pure continuous polyester fibers shrink strong under the influence of heat. First the modified endless polyester fiber according to the invention makes it possible for the first time to produce a fiber that is exposed to moisture and The effect of heat remains dimensionally stable, which is an essential requirement for floor coverings is.
