Description
Spinn düse zur Herstellung von Kunstfäden. Zur Herstellung der Spinndüsen für die Kunstfädenindustrie standen bisher hauptsächsächkoh zwei Baustoffe zur Verfügung: einerseits Glas, anderseits Metall; beide Baustoffe weisen wesentliche Mißstände auf.Spinning nozzle for the production of synthetic threads. For the manufacture of the spinnerets So far, two main building materials have been available for the synthetic thread industry: on the one hand glass, on the other hand metal; both building materials show major deficiencies on.
Die Düsen selbst können entweder als Angerhutförmige Gebilde, teils als planparallele Platten ausgeführt sein, in denen Austrittsöffnungen in beliebiger Zahl und Größe angeordnet sind.The nozzles themselves can either be in the form of a hat-shaped structure, partly be designed as plane-parallel plates, in which outlet openings in any Number and size are arranged.
Der besondere Übelstand der Metalldüsen liegt darin, daß die Bodenstärke nur Bruchteile eines Millimeters betragen darf, da sonst das Bohren der fein-en Löcher unmöglich. wird. Die geringe Bodenstärke hat aber den Nachteil, daß -sie den Auszug der Spinnlösung bedeutend erschwert, da die Gleich-mäßigkeit -der Fäden eine bestimmte Länge der Kapillare zur Voraussetzung hat.The particular drawback of metal nozzles is that the floor thickness may only be a fraction of a millimeter, otherwise drilling the fine Holes impossible. will. The small base thickness has the disadvantage that -sie the extraction of the spinning solution is made significantly more difficult because of the evenness of the threads a certain length of the capillary is a prerequisite.
Der Nachteil, des Glasest als Düsenbaustoff tritt besonders dadurch hervor, daß die henötigten feinen Löcher nicht anders herzustell-en -sind, als daß in,eine Glasplatte Platindrähte eingeschmolzen werden, die nachher wieder herausgelöst werden müssen. Ganz abgesehen von der sch:voierigen Herstellung .der Platten, der geringen Bruchfestigkeit des Glases und -der Kostbarkeit des ein-ebetteten Metalles, von dein nur ein gewisser Prozentsatz wiedergewonnen werden kann, treten durch das Schmelzen Spannungsersäheinungen im Glase auf, die sich selbst durch ganz vorsichtiges Abkühlen nicht vermeiden lassen, ,Lind die sich im Betriebe durch das Zerspringen der Düsen unangeneh#n bemerkbar inachen.The disadvantage of using the glass residue as a nozzle building material occurs particularly because of this shows that the necessary fine holes cannot be produced in any other way than that Platinum wires are melted into a glass plate, which are then removed again Need to become. Quite apart from the difficult production of the panels, the low breaking strength of the glass and the preciousness of the embedded metal, only a certain percentage of yours can be recovered through that Melting tension in the glass, which is self-evident by being very careful Do not let it cool down, and that can be caused by shattering in the establishment the nozzles are noticeable unpleasantly.
Der Gegenstand der Erfindung Iöst alle Schwierligkeiten in überraschend einfacher Weise da-durch, daß an Stelle von Glas oder Metall die sogenannten Phenolformaldehyd-Kondensationsprodukte angewendet werden. Es ist bek-annt, daß derartige Kondensationsprodukte sich leicht in Form von Platt-en erhalten lassen, die mit großer Festigkeit eine leichte BeailbeitungsmögKchl#:.eit und Widerstandsfähigikeit gegen Säure und Alkali Verbinden.The object of the invention surprisingly solves all difficulties simply by the fact that instead of glass or metal the so-called phenol-formaldehyde condensation products be applied. It is known that such condensation products are easy in the form of plates, which are very strong and easy to work with and resistance to acid and alkali bonding.
Urn -diese Platten mit Löchern zu vers-ehen, hat.man nicht mehr nötig, auf das teure Platin zurück,zugreifen, sond-ern kann Drähte von irgendwelchem anderen, auch unedlen Metall benutzen, so z. B. Kupfer.In order to provide these plates with holes, one no longer has to to access the expensive platinum, but can use wires from any other, also use base metal, e.g. B. Copper.
Werden diese Kupferdräfite nach der in der üblichen Weise vollzogenen Härtung der Pgat-Len durch irgendeine Säure, ein Alkali oder durch E lektrolyse herausgelöst, so erhält man auf einfachstem Weigeeine allen Anforderungen gerecht werdende Spinndüse.If these Kupferdräfite dissolved out after the accomplished in the usual manner, hardening of the Pgat-Len by any acid, an alkali or by E lektrolyse, is obtained in the simplest Weigeeine all requirements becoming spinneret.
Da die K-ondensationsprodukte sich durch ihre vorzügliche Beatbeitungsfähigkeit allem anderen Material gegenüber vorteilhaft aus-7-eichnen, so wird die Herstellung von Spinndüsen zweckmäßig so vorgenommen, daß eine Hohlform von zylindrischer oder mehrkantiger Gestalt, in der Metalldrähte parallel ausgespannt sind, mit dem Koudensationsprodukt in geschmolzener Form gefüllt -,verden, worauf der Inh-alt der Form in beikannter Weise einem Härtungsprozeß unterworfen wird. Nach Herausnähme aus der Formerhält man einen von zahlreichen Metglldräht-en durchzogenen ]älock, der jetzt auf irgendtine Weise, sei es durch iSägen, Schneiden usw., in einzelne Platten unterteilt wird. Nach Herauslösun,g der Metallfäden i-st die Spinndüse f ertig.Since the condensation products are advantageous compared to all other materials due to their excellent ventilation ability, the production of spinnerets is expediently carried out in such a way that a hollow shape of cylindrical or polygonal shape, in which metal wires are stretched in parallel, with the condensation product filled in molten form - verden, whereupon the content of the form is subjected to a hardening process in a known manner. After removing it from the mold, one obtains a block of metal, criss-crossed by numerous metal wires, which is now divided into individual plates in some way, be it by sawing, cutting, etc. After Herauslösun, the metal filaments g i-st spinneret f inished.
Die so erhaltenen Platten werden in eine Fassung aus irgendwelchem, zweckmäßig gewähltern Stoff eingesetzt.The plates obtained in this way are placed in a holder made of any appropriately chosen material used.
