Description

Verfahren zur Herstellung von elastischen Fäden hTach dem Patent 6 13 2 3 5 werden Kautschukfäden derart hergestellt, daß Kernfäden aus durch Kautschuk nicht absorbierbaren Natur- oder Kunstfasern mit Kautschuk überzogen, vulkanisiert und die Kernfäden innerhalb der so erhaltenen kombinierten Fäden gegebenenfalls nach ihrer Weiterverarbeitung dann durch Einwirkung eines Ätz- oder Carbonisierungsmittels, z. B. Aceton, gelöst oder in. ihrem Gefüge zerstört oder nach einer Vorbehandlung mit Säure oder Lauge durch Einwirkung von Hitze oder Belichtung zermürbt bzw. aufgelöst werden. Ebenso können dabei die nach einer Behandlung vorerwähnter Art im Innern der Kautschukfäden etwa noch vorhandenen Kernfädenrückstände durch eine Nachbehandlung mit Lösungs-oder Spülmitteln entfernt werden.Process for the production of elastic threads According to the patent 6 1 3 2 3 5 rubber threads are produced in such a way that core threads made of natural or synthetic fibers which cannot be absorbed by rubber are coated with rubber, vulcanized and the core threads within the combined threads thus obtained, optionally after their further processing by the action of an etching or carbonizing agent, e.g. B. acetone, dissolved or their structure destroyed or, after pretreatment with acid or alkali, worn down or dissolved by the action of heat or exposure to light. Likewise, any core thread residues still present in the interior of the rubber threads after a treatment of the type mentioned above can be removed by an aftertreatment with solvents or rinsing agents.

In Verfolg weiterer Arbeiten wurde nun gefunden, dar man das Verfahren gemäß Hauptpatent auch derart durchführen kann,-daß man an Stelle von Kautschuk andere in trockenem Zustande elastische Überzugsmaterialien, z. B. Kautschukersatzstoffe, wie das Äthylendichloridnatriumtetrasulfidreaktionsprodukt, verwendet.As a result of further work, it has now been found that the process can be used according to the main patent can also be carried out in such a way that instead of rubber other coating materials which are elastic in the dry state, e.g. B. rubber substitutes, such as the ethylene dichloride sodium tetrasulfide reaction product is used.

Der besondere Vorteil der Verwendung solcher anderer in trockenem Zustande ielastischer Überzugsmaterialien an Stelle, von Kautschuk besteht dabei vor allem darin, daß man damit im Sinne des Verfahrens gemä(.') Hauptpatent auch elastische Fäden oder Verarbeitungsprodukte solcher; z. B. Gewebe, herstellen kann, welche für viele Zwecke, z. B. für chemische Apparaturen, Auskleidungen, Filtriertücher u. dgl., auf Grund der entsprechenden Widerstandsfähigkeit ihres jeweiligen Baustoffes im Gegensatz zu Kautschuk geeignet oder zum mindesten geeigneter als dieser sind.The particular advantage of using such other in dry State of ielastic coating materials instead of rubber above all in the fact that in the sense of the procedure according to (. ') main patent, too elastic threads or processed products of such; z. B. fabric, can produce, which can be used for many purposes, e.g. B. for chemical apparatus, linings, filter cloths and the like, due to the corresponding resistance of their respective building material in contrast to rubber are suitable or at least more suitable than this.

Die Durchführung des Verfahrens unter Verwendung der .anderen üb-erzugsmaterialien an Stelle von Kautschuk ist dabei im allgemeinen die gleiche wie gemäß Hauptpatent, wenn. natürlich auch, ebenso wie bei diesem, je nach Art des verwendeten Baustoffes Kernfaden- und Umspinnungsmaterial usw. die jeweils günstigsten Arbeitsbedingungen, wie Auswahl des Lösungsmittels zum Entfernen des Natur- oder Kunstfaser fadens u. dgl. m., von Fall zu Fall auszuwählen sind.Carrying out the process using the other covering materials instead of rubber is generally the same as according to the main patent, if. of course, as well as with this one, depending on the type of building material used Core thread and wrapping material etc. the most favorable working conditions in each case, such as selection of the solvent to remove the natural or synthetic fiber thread u. Like. m. To be selected on a case-by-case basis.

Der überzugsmantel ist dabei im allgemeinen, wie im Hauptpatent ausgeführt, hinreichend porös, um das Lösungsmittel für den Kernfaden hindurchtreten zu lassen. Gegebenenfalls können dem Überzugsmäterial aber auch noch besondere Zusätze einverleibt werden, um seine Porosität zu erhöhen. Um nach Herauslösen des Kernfadens diese Porösität wieder zu beseitigen, kann das fertige Gebilde, z. B. Gewebe, mit Quellungsmitteln für das @tltylenchloridnatriumtetrasuliidreaktionsprodukt nachbehandelt «erdet wodurch dessen Poren geschlossen werdett.-,>'b:` YThe cover jacket is generally, as stated in the main patent, sufficiently porous to allow the solvent for the core thread to pass through. If necessary, however, special additives can also be incorporated into the coating material to increase its porosity. To after loosening the core thread this Removing porosity can be done Structure, e.g. B. Tissue, with swelling agents for the @tltylene chloride sodium tetrasuloid reaction product aftertreated «grounds which closes its pores .-,> 'b:` Y
