Description

Verfahren zur Oberflächenbehandlung eines Körpers aus gebündelten Hohlfäden Die Erfindung betrifft ein Verfahren zur Oberflächenbehandlung eines Körpers aus gebündelten Hohlfäden.Method of surface treatment of a body made of bundled Hollow filaments The invention relates to a method for the surface treatment of a body from bundled hollow fibers.

Derartige Körper werden im allgemeinen in der Weise hergestellt, daß zunächst Hohlfäden spinntechnisch erzeugt werden, die insbesondere aus Thermoplasten, z. B. Polyolefinen oder Polystyrol, bestehen. Diese Hohlfäden werden in geeigneter Weise gebündelt und entsprechend den gewünschten Ausmaßen abgeschnitten. Dieses Abschneiden kann mittels geeigneter Schneideinrichtungen oder z. B. auch erwärmter Drähte erfolgen. Such bodies are generally manufactured in such a way that that hollow fibers are initially produced by spinning technology, in particular made of thermoplastics, z. B. polyolefins or polystyrene exist. These hollow fibers are more suitable Bundled in a way and cut according to the desired dimensions. This Cutting can be done by means of suitable cutting devices or z. B. also warmer Wires are made.

Das Verfahren gemäß der Erfindung bezieht sich nun auf die Oberflächenbehandlung eines Körpers aus gebündelten Hohlfäden der eingangs genannten Art und ist dadurch gekennzeichnet, daß die stirnseitigen Querschnitte der Hohlfäden durch Plastifizieren in den gewünschten Verschließungsgrad gebracht und gleichzeitig die Stirnenden der Hohlfäden untereinander verbunden werden. The method according to the invention now relates to surface treatment a body made of bundled hollow fibers of the type mentioned at the beginning and is therefore characterized in that the end cross-sections of the hollow fibers are plasticized brought into the desired degree of closure and at the same time the front ends of the Hollow fibers are connected to one another.

Es ist zwar schon ein Verfahren bekanntgeworden, bei welchem Körper aus gebündelten Fäden mittels einer besonderen Abschneidvorrichtung hergestellt wurden. Das vorbekannte Verfahren enthält jedoch keine Hinweise auf eine Oberflächenbehandlung eines Körpers aus gebündelten Hohlfäden, wie es Gegenstand der vorliegenden Erfindung ist. It is true that a procedure has already become known, in which body made from bundled threads by means of a special cutting device became. However, the previously known method does not contain any indications of a surface treatment a body of bundled hollow fibers, as is the subject of the present invention is.

Das vorübergehende Plastifizieren der Stirn enden der Hohlfäden und ihr gegenseitiges Verbinden kann zweckmäßigerweise durch Verschmelzung des Materials der Stirnenden vorgenommen werden. Es ist ferner möglich, das vorübergehende Plastifizieren der Stirnenden der Hohlfäden und ihr gegenseitiges Verbinden durch Anlösungsvorgänge und nachfolgende Trocknung durchzuführen. The temporary plasticizing of the forehead ends of the hollow fibers and their mutual connection can expediently by fusing the material of the front ends. It is also possible to temporarily plasticize of the ends of the hollow fibers and their mutual connection through dissolution processes and carry out subsequent drying.

Wird das Plastifizieren in Form einer Wärmeanschmelzung durchgeführt, so kann dieses durch ein an die Stirnenden angelegtes, von außen erwärmtes Tuch durchgeführt werden, wobei das Tuch nach der Verschmelzung gegebenenfalls wieder abgezogen wird. An Stelle des Tuches kann auch eine Folie aus Metall oder Kunststoff verwendet werden. Letztere kann sich dabei als Verstärkungskörper mit dem Material der Fläche der Hohlfäden verbinden. Das Anschmelzen der Stirnenden kann auch mittels Infrarotstrahlung oder mit Hilfe einer an den Stirnenden vorbeistreichenden Flamme erfolgen. If the plasticizing is carried out in the form of heat fusion, this can be done through a cloth that is placed on the forehead and warmed from the outside be carried out, with the cloth again after the fusing, if necessary is deducted. Instead of the cloth, a foil made of metal or plastic can also be used be used. The latter can act as a reinforcing body with the material connect the surface of the hollow fibers. The front ends can also be melted by means of Infrared radiation or with the help of a flame sweeping past the forehead ends take place.

Die Flächen der Stirnenden der Hohlfäden können beliebig geformt und je nach dem gewünschten Verwendungszweck des fertigen Körpers, z. B. kugel-oder halbkugelförmig, ausgebildet werden. Während des vorübergehenden Plastifizierens können Verstärkungskörper oder andere Verstärkungsmittel, wie Fäden, Vliese, Gewebe od. dgl., eingebettet werden. The surfaces of the front ends of the hollow fibers can be shaped as desired and depending on the desired use of the finished body, e.g. B. spherical or hemispherical. During temporary plasticizing can be reinforcing bodies or other reinforcing means, such as threads, fleeces, fabrics or the like., are embedded.

Insbesondere können die Verstärkungsmittel auch aus Glasfasern bestehen. Die Einbettung kann dabei ganz oder teilweise erfolgen, und es ist ferner möglich, das teilweise eingebettete Verstärkungsmaterial nachträglich mit einem Lack oder einem härtbaren Gießharz zu imprägnieren.In particular, the reinforcing means can also consist of glass fibers. The embedding can take place in whole or in part, and it is also possible the partially embedded reinforcement material subsequently with a varnish or to be impregnated with a hardenable casting resin.

Soll die Stirnfläche der Hohlfäden eine poröse Struktur aufweisen, ist es zweckmäßig, die Stirnenden der Hohlfäden nur relativ schwach vorübergehend zu plastifizieren. Umgekehrt ist es möglich, eine nicht poröse Deckschicht der Fläche der Hohlfäden in der Weise herzustellen, daß die Stirnenden der Hohlfäden vorübergehend relativ stark plastifiziert werden. Man erhält dadurch Körper mit einer gut ausgebildeten Folie, aus welcher die Hohlfäden organisch verbunden herauswachsen. Solche Körper können gegebenenfalls mit weiteren Zusatzstoffen, wie eingeschweißten Folien, Glasplatten, Metallplatten od. dgl., als Fußbodenbelag oder auch als Wandbekleidung mit außerordentlich guten Eigenschaften eingesetzt werden. If the end face of the hollow fibers is to have a porous structure, it is advisable to temporarily keep the ends of the hollow fibers relatively weak to plasticize. Conversely, it is possible to have a non-porous top layer of the surface of the hollow fibers in such a way that the front ends of the hollow fibers are temporarily are relatively strongly plasticized. This gives a body with a well-developed one Foil from which the hollow filaments grow organically connected. Such bodies can optionally with other additives, such as welded foils, glass plates, Metal plates or the like, as a floor covering or as a wall covering with extraordinary good properties are used.

An Hand der Figuren soll das Verfahren gemäß der Erfindung am Beispiel bevorzugt hergestellter Körper und deren Oberflächenbehandlung näher er läutert werden. With reference to the figures, the method according to the invention is intended using the example preferred manufactured body and its surface treatment he explains in more detail will.

F i g. 1 bis 3 stellen im Schnitt Körper aus gebündelten Hohlfäden mit Oberflächen dar, die einen verschiedenen Verschließungsgrad aufweisen; in Fig.4 ist ein Körper im Schnitt dargestellt, der eine konvexe Form aufweist. F i g. 1 to 3 represent in section bodies made of bundled hollow fibers with surfaces that have a different degree of closure; in Fig. 4 a body is shown in section, which has a convex shape.

In F i g. 1 sind mit 11 die Hohlfäden bezeichnet. In Fig. 1, 11 denotes the hollow fibers.

In Richtung der Pfeile 16 findet eine Wärmebeein- flussung, beispielsweise eine Infrarotstrahlung, statt.In the direction of the arrows 16 there is a heat concentration river, for example infrared radiation instead.

Dadurch bilden sich an den Stirgenden der Hohlfäden Verdickungen 12 aus. Je nach der Stärke der Infrarotstrahlung bzw. einer anderen beliebigen Wärmeanwendung kann durch vorübergehendes Plastifizieren ein beliebiger Verschließungsgrad der Deck- oder Stinifläche erzielt werden. This causes thickenings to form on the ends of the hollow fibers 12 off. Depending on the strength of the infrared radiation or any other heat application any degree of closure of the Top or stini surface can be achieved.

Die Ausführungsform von Fig.2 unterscheidet sich von Fig. 1 dadurch, daß die Hohlfäden der letzteren gegenseitige Zwischenräume 13 besitzen, während bei F i g. 2 zumindest im Bereich der linearen Berührungszone der Hohlfäden keine solchen Zwischenräume vorhanden sind. Wie in F i g. 2 weiter gezeigt, sind die Verdickungen 12 nur so weit ausgebildet, daß eine Verstärkung der Oberfläche erfolgt ist, daß jedoch noch eine gewisse Porosität aufrechterhalten wird. The embodiment of Fig.2 differs from Fig. 1 in that that the hollow fibers of the latter have mutual spaces 13, while at F i g. 2, at least in the area of the linear contact zone of the hollow fibers, none such spaces are present. As in Fig. 2 further shown are the thickenings 12 formed only so far that a reinforcement of the surface has occurred that however, some porosity is still maintained.

In F i g. 3 ist in der Stirnfläche, die aus den Verdickungen 12 der Hohlfäden 11 gebildet wird, eine aus Glasfasern bestehende Verstärkung 14 eingebettet. Diese Einbettung kann auch ganz erfolgen. In Fig. 3 is in the end face, which consists of the thickenings 12 of the Hollow fibers 11 is formed, a reinforcement 14 made of glass fibers is embedded. This embedding can also be done entirely.

Im gezeigten Beispiel ist die Verstärkung nur teilweise in die Deckschicht eingebettet und durch ein Imprägnierungsmittel, beispielsweise ein ausgehärtetes Gießharz, vergossen.In the example shown, the reinforcement is only partially in the top layer embedded and by an impregnating agent, for example a hardened one Cast resin, potted.

Nach dem oben geschilderten Herstellungsverfahren entstehen zunächst plattenförmige Körper mit einer Deckschicht gemäß Fig. 1, 2 oder 3. Die der ersten Deckschicht gegenüberliegende Seite der plattenförmigen Körper kann nachträglich durch ebensolche Anschmelzungs- oder Anlösungsvorgänge mit einer weiteren Deckschicht aus Hohlfäden mit oder ohne zusätzliche Verstärkungsmittel versehen werden. Die Erzeugung dieser zweiten Deckschicht kann in vielen Fällen nach einer vorhergehenden Verformung der plattenförmigen Hohlfädenkörper mit nur einer Deckschicht vorgenommen werden. After the manufacturing process outlined above, first of all arise plate-shaped body with a cover layer according to FIG. 1, 2 or 3. Those of the first Cover layer opposite side of the plate-shaped body can subsequently by melting or dissolving processes with a further top layer made of hollow fibers can be provided with or without additional reinforcing agents. the In many cases, this second top layer can be produced after a previous one Deformation of the plate-shaped hollow fiber body made with only one cover layer will.

Es ist beispielsweise möglich, die Körper mit nur einer Deckschicht platten- oder streifenweise um einen konvexen Formkörper mit innenliegender Deckschicht herumzuwickeln oder auch unter Wärmeanwendung und dadurch erfolgender vorübergehender Erweichung an den Formkörper anzuschmiegen und nach dieser Formgebung erst auf der konvexen Seite außen mit der zweiten Deckschicht zu versehen. Dadurch entstehen nichtebene, plattenförmige Körper komplizierterer Gestalt, wie z.B Bootskörper, Tragflächen für Flugzeuge oder kistenförmige Körper. For example, it is possible to have the body with just one top layer Plate or strip around a convex shaped body with an inner cover layer wrapping around or with the application of heat and thus temporary Softening to cling to the molded body and only after this shaping on the to provide the convex side with the second outer layer on the outside. This creates non-planar, plate-shaped bodies of more complex shape, such as boat hulls, Aircraft wings or box-shaped bodies.

In F i g. 4 ist dargestellt, wie ein nichtebener, plattenförmiger Körper erzeugt bzw. seine Oberfläche behandelt wird. Um den konvexen Formkörper ist der plattenförmige Hohlfädenkörper mit der ersten Deckschicht 18 gewickelt. Dabei ist ersichtlich, daß die Kapillaren 20 sich an der Rundung 19 mit kleinem Krümmungsradius stark spreizen. In Fig. 4 is shown as a non-planar, plate-shaped one Body is generated or its surface is treated. Around the convex shaped body the plate-shaped hollow fiber body is wound with the first cover layer 18. It can be seen that the capillaries 20 on the curve 19 with a small Spread the radius of curvature strongly.

Nach der Umwicklung wurde die zweite Deckschicht 21 erzeugt, die, wie bereits erwähnt, ebenfalls noch Verstärkungskörper erhalten kann. Die Zwischenräume zwischen den Hohlfäden 20 sind mit einem Imprägnierungsmittel 22 gefüllt.After the wrapping, the second cover layer 21 was produced, which, As already mentioned, reinforcement bodies can also be obtained. The spaces in between between the hollow fibers 20 are filled with an impregnating agent 22.
