Description

DEUTSCHESGERMAN

Die Erfindung bezieht sich auf die Herstellung von Fasern aus thermoplastischen Stoffen in viskosem Zustand, insbesondere von Glasfasern.The invention relates to the production of fibers from thermoplastic materials in a viscous state, especially of glass fibers.

Sie betrifft insbesondere diejenigen bekannten Vorrichtungen, bei welchen die geschmolzene Masse in das Innere eines mit hoher Geschwindigkeit um seine Achse sich drehenden Schleuderkörpers eingeführt wird, in dessen Mantel eine oder mehrere Reihen von öffnungen angeordnet sind. Bei einer derartigen Vorrichtung wird die Masse unter der Wirkung der Zentrifugalkraft durch die genannten öffnungen in Form von feinen Strömen ausgeschleudert, und diese werden dabei einer Ziehwirkung unterworfen, durch die sie zu Fasern umgewandelt werden.It relates in particular to those known devices in which the molten mass in introduced the interior of a spinner rotating at high speed on its axis is, in the jacket one or more rows of openings are arranged. In such a device the mass is under the effect of centrifugal force through the openings mentioned in Form of fine streams ejected, and these are thereby subjected to a pulling effect, through which they are converted into fibers.

Das Neue der Erfindung besteht darin, daß die 1S Öffnungen im Mantel des Schleuderkörpers verschieden große Durchmesser besitzen.The novelty of the invention is that the 1 S openings in the mantle of the centrifugal body have different sized diameters.

Zufolge der unterschiedlichen Durchmesser der Schleuderöffnungen läßt sich ein Gemisch aus Fasern verschiedener Durchmesser erzielen, beispielsweise ein solches aus sehr feinen Fasern und aus gröberen Fasern.As a result of the different diameters of the centrifugal openings, a mixture of fibers can be produced achieve different diameters, for example one made of very fine fibers and coarser ones Fibers.

Obschon die Fasern aus dem gleichen Material bestehen, besitzen sie infolge der verschiedenen Durchmesser unterschiedliche thermoplastische Eigenschaften. Dies kommt daher, daß die bei der Faserherstelhing eintretende Abkühlung sich auf die Fasern verschiedener Durchmesser verschieden auswirkt, wodurch sich Änderungen in der Struktur des Glases ergeben.Although the fibers are made of the same material, they have different thermoplastic properties due to their different diameters. This is because the cooling that occurs during fiber production affects the fibers Different diameters have different effects, causing changes in the structure of the glass result.

Die aus Fasern verschiedener Durchmesser gebildeten Gemische von Fasern können nach einem noch nicht zum Stande der Technik gehörenden Verfahren unter Verschweißung der Fasern durch Wärmeeinwirkung zu Matten, Platten oder Formstücken verarbeitet werden.The mixtures of fibers formed from fibers of different diameters can after a still Processes that do not belong to the state of the art and involve welding of the fibers by the action of heat can be processed into mats, panels or shaped pieces.

Im Mantel des Schleuderkörpers können mehrere Reihen von Schleuderöffnungen vorgesehen sein, wobei jede Reihe Öffnungen des gleichen Durchmessers besitzt, während die Durchmesser von einer zur anderen Reihe oder von einer Reihengruppe zu einer anderen Reihengruppe verschieden sein können. Gegebenenfalls können auch die öffnungen ein und derselben Reihe verschiedene Durchmesser haben.Several rows of centrifugal openings can be provided in the jacket of the centrifugal body, wherein each row has openings of the same diameter, while the diameters from one to the other Row or can be different from one row group to another row group. Possibly the openings in one and the same row can also have different diameters.

Der Mantel des Schleuderkörpers kann beispielsweise Reihen von Schleuderöffnungen aufweisen, von denen die einen, z. B. die höher gelegenen, einen kleineren Durchmesser, beispielsweise 0,8 mm, haben als die anderen, deren Durchmesser etwa 1 bis 1,2 mm sein kann.The jacket of the centrifugal body can, for example, have rows of centrifugal openings, of which one, z. B. the higher located, have a smaller diameter, for example 0.8 mm than the others, the diameter of which can be about 1 to 1.2 mm.

Die Verbesserung gemäß der Erfindung läßt sich auch anwenden, um Fasern von im wesentlichen gleichem Durchmesser zu erzeugen, selbst wenn die Temperaturverhältnisse der verschiedenen Reihen von Vorrichtung zur Herstellung von Fasern aus thermoplastischen Stoffen, wie GlasThe improvement according to the invention can also be applied to fibers of essentially produce the same diameter, even if the temperature conditions of the different series of Device for the production of fibers from thermoplastic materials such as glass

Öffnungen von einer zur anderen Reihe unterschiedlich sind. Diese Unterschiede lassen sich dadurch ausgleichen, daß man die Reihen von öffnungen größeren Durchmessers in den kälteren Zonen vorsieht, wo das Glas viskoser ist.Openings are different from one row to the other. These differences can be made through this compensate for the fact that the rows of openings of larger diameter are provided in the colder zones, where the glass is more viscous.
