Abstract

The invention relates to specially coated bobbins, a process for their fabrication and their use in the production of glass fibres.

Description

Die vorliegende Erfindung betrifft speziell beschichtete Hülsen, ein Verfahren zu ihrer Herstellung sowie ihre Verwendung bei der Herstellung von Glasfasern.The present invention relates to specially coated sleeves, a process for their production and their use in the production of glass fibers.

Bei der Herstellung von Glasfasern werden die Glasfasern normalerweise, nachdem sie aus dem sogenannten Bushing gezogen worden sind, auf sogenannte Hülsen aufgewickelt. Diese aufgewickelten Glasfasern werden anschließend gemeinsam mit der Hülse, dem sogenannten Cake, getrocknet. Nach dem Trocknungsprozeß wird die Hülse entfernt, indem sie seitlich aus dem sogenannten Cake herausgezogen wird. Die gewickelte Glasfaser wird anschließend weiter verarbeitet. Die Hülsen bestehen aus verstärktem oder unverstärktem Papier bzw. aus verstärktem oder unverstärktem Kunststoff und sind unbeschichtet oder teilweise mit Polyurethanen beschichtet.In the manufacture of glass fibers, the glass fibers are usually wound onto so-called cores after they have been pulled out of the so-called bushing. These wound glass fibers are then dried together with the sleeve, the so-called cake. After the drying process, the sleeve is removed by pulling it out of the side of the cake. The wound glass fiber is then processed further. The sleeves are made of reinforced or unreinforced paper or reinforced or unreinforced plastic and are uncoated or partially coated with polyurethanes.

Bei dem seitlichen Herausziehen der Hülse aus dem Cake wurde bisher immer ein Teil der aufgewickelten Glasfaser mit herausgezogen, der dann der weiteren Verarbeitung nicht mehr zur Verfügung stand und als Abfall die Ausbeute abgewickelter Glasfaser stark vermindern konnte.When pulling the sleeve out of the cake laterally, part of the wound glass fiber has always been used pulled out, which was then no longer available for further processing and could significantly reduce the yield of unwound glass fiber as waste.

Aufgabe war es daher ein Verfahren zur Verfügung zu stellen, bei dem der oben bezeichnete Glasabfall nicht mehr anfällt.The task was therefore to provide a process in which the above-mentioned glass waste no longer arises.

Diese Aufgabe konnte durch das erfindungsgemäße Verfahren sowie durch die zur Verfügungstellung der neuen erfindungsgemäßen Hülsen gelöst werden.This problem could be solved by the method according to the invention and by the provision of the new sleeves according to the invention.

Gegenstand der Erfindung sind Hülsen, auf die die Glasfaser bei ihrer Herstellung aufgewickelt wird und die sich dadurch auszeichnen, daß sie mit Siliconölen und/oder -harzen beschichtet worden sind.The invention relates to sleeves on which the glass fiber is wound during its manufacture and which are characterized in that they have been coated with silicone oils and / or resins.

Ein weiterer Gegenstand der Erfindung ist ein Verfahren zur Herstellung der erfindungsgemäßen Hülsen, welches dadurch gekennzeichnet ist, daß

  • a) das Siliconöl oder das Siliconharz in Mengen zwischen 5 und 100 g/m² , vorzugsweise zwischen 10 und 70 g/m² auf die Hülse appliziert wird, wobei bei der Verwendung von Siliconharz diesen vorher ein üblicher Katalysator in Mengen von 100 bis 5000 ppm zugesetzt wird, und
  • b) die so behandelte Hülse unter Luftzutritt im Ofen bei Temperaturen zwischen 60° und 120°C über einen Zeitraum von 15 Minuten bis 2 Stunden getrocknet wird.
Another object of the invention is a method for producing the sleeves according to the invention, which is characterized in that
  • a) the silicone oil or the silicone resin is applied to the sleeve in amounts between 5 and 100 g / m², preferably between 10 and 70 g / m², with the use of silicone resin previously adding a conventional catalyst in amounts of 100 to 5000 ppm will, and
  • b) the sleeve thus treated is dried in the oven at temperatures between 60 ° and 120 ° C. over a period of 15 minutes to 2 hours.

Das Siliconöl bzw. -harz wird in geeigneter Weise, d.h. z.B. durch Walzenlackierung, Tauchen oder Spritzauftrag, auf die Hülse appliziert. Werden Siliconharze verwendet, wird diesen als Katalysatoren Salze von Zinn, Eisen, Titan, Blei oder Aluminium einzeln oder im Gemisch zugesetzt, damit die Harze mit der Hülse vernetzen können. Bevorzugt werden als Katalysatoren Titantetrabutylat und/oder Dibutylzinndilaurat verwendet.The silicone oil or resin is suitably, i.e. e.g. applied to the sleeve by roller coating, dipping or spraying. If silicone resins are used, salts of tin, iron, titanium, lead or aluminum are added to these individually or as a mixture, so that the resins can crosslink with the sleeve. Titanium tetrabutylate and / or dibutyltin dilaurate are preferably used as catalysts.

Die erfindungsgemäßen Hülsen werden bei der Aufwicklung von Glasfasern verwendet.The sleeves according to the invention are used in the winding of glass fibers.

Die Erfindung soll anhand nachfolgender Beispiele näher erläutert werden.The invention is illustrated by the following examples.

Bei der Verwendung der bisherigen Hülsen bei der Aufwicklung verschiedener Glasfasern wurde beim Herausziehen der Hülse aus dem sogenannten Cake die aufgewickelte Glasfaser zu einem großen Teil mit herausgezogen (siehe Tabelle 1). Diese mit der Hülse herausgezogene Glasfaser geht dem weiteren Prozeß bzw. der weiteren Verarbeitung verloren und mindert daher in erheblichem Maße die Ausbeute.When using the previous sleeves when winding various glass fibers was when pulling out The core of the so-called cake is largely pulled out of the wound glass fiber (see Table 1). This glass fiber drawn out with the sleeve is lost to the further process or further processing and therefore considerably reduces the yield.

Die bisher verwendeten Hülsen wurden nach dem erfindungsgemäßen Verfahren behandelt und ebenfalls bei der Aufwicklung verschiedener Glasfasern eingesetzt. Wie der Tabelle 1 zu entnehmen ist, konnten die erfindungsgemäßen Hülsen fast ohne Verlust an Glasfasern aus dem sogenannten Cake herausgezogen werden. Damit ist der Verlust an Glasfasern bei der Verwendung der erfindungsgemäßen Hülsen erheblich geringer als bei der Verwendung der bekannten Hülsen.The tubes used up to now were treated by the method according to the invention and were also used in the winding of various glass fibers. As can be seen from Table 1, the sleeves according to the invention could be pulled out of the cake with almost no loss of glass fibers. The loss of glass fibers when using the sleeves according to the invention is thus considerably less than when using the known sleeves.
