Gegenstand des Hauptpatents 1148 520 ist ein Verfahren zum Veredeln von geformten Gebilden aus hochpolymeren Polyestern aus mehrbasischen Säuren und mehrwertigen Alkoholen, insbesondere aus sechsgliedrige Carbocyclen enthaltenden Polyestern, ζ. B. des Polyäthylenterephthalattyps, wobei man diese vor oder nach dem Verstrecken kurze Zeit bei Temperaturen über 200° C, vorzugsweise oberhalb 220° C, mit solchen chemischen Stoffen behandelt, die unter diesen Bedingungen mit der Oberfläche der hochpolymeren Gebilde chemisch reagieren.The subject of the main patent 1148 520 is a Process for the finishing of shaped structures made of high-polymer polyesters from polybasic Acids and polyhydric alcohols, in particular from polyesters containing six-membered carbocycles, ζ. B. of the polyethylene terephthalate type, this before or after stretching for a short time treated with such chemical substances at temperatures above 200 ° C, preferably above 220 ° C, which under these conditions with the surface of the high polymer structures chemically react.

Vorteilhafterweise arbeitet man bei solchen Temperaturen, die in der Nähe des Schmelzpunktes des polymeren Materials bis etwa 50° C darüberliegen. Die Entfernung überschüssigen Behandlungsmittels erfolgt, soweit erforderlich, durch Auswaschen mit einer geeigneten Waschlösung.It is advantageous to work at temperatures close to the melting point of the polymeric material to about 50 ° C above this. Excess treatment agent is removed, if necessary, by washing out with a suitable washing solution.

In weiterer Ausgestaltung des Verfahrens des Hauptpatents wurde nun gefunden, daß bei der Anwendung flüchtiger Stoffe überschüssiges Behandlungsmittel in einfacher Weise dadurch entfernt werden kann, daß man das Material nach der thermischen Behandlung über auf über 200 bis 350° C erhitzte Flächen, z. B. Heizplatten, Bügeleisen usw. führt oder das Material einem entsprechend heißen Luftstrom oder einer Infrarotbestrahlung aussetzt. Selbstverständlich ist es möglich, gleichzeitig Kombinationen dieser Maßnahmen anzuwenden.In a further embodiment of the process of the main patent, it has now been found that in the application Volatile substances excess treatment agent can be removed in a simple manner it can be that the material after the thermal treatment over to over 200 to 350 ° C heated surfaces, e.g. B. hot plates, irons, etc. leads or the material is hot accordingly Exposed to air currents or infrared radiation. It is of course possible to use combinations at the same time to apply these measures.

Als chemisch reagierende Stoffe kommen die im Hauptpatent genannten Verbindungen in Betracht, wobei jedoch Voraussetzung ist, daß diese Stoffe bei Temperaturen oberhalb 200° C flüchtig sind. Die Durchführung des Verfahrens geschieht in der im Hauptpatent beschriebenen Weise, wobei man jedoch die Temperaturbedingungen so wählen wird, daß eine Zersetzung der Verbindungen, die zu einer Verfärbung des behandelten Materials führen könnte, vermieden wird.The compounds mentioned in the main patent can be used as chemically reacting substances, However, it is a prerequisite that these substances are volatile at temperatures above 200 ° C. the The process is carried out in the manner described in the main patent, but with the temperature conditions will be chosen so that a decomposition of the compounds leading to a discoloration of the treated material is avoided.

Die Arbeitsweise der Entfernung des flüchtigen Behandlungsmittels durch Verdampfen, sei es durch Überleiten über heiße Flächen oder durch Durchführen des behandelten Materials durch einen heißen Luftstrom bzw. durch Infrarotbestrahlung, ist von besonderer Bedeutung bei der Veredlung von Fäden, da sich das Verfahren bequem auf einer entsprechend umgebauten Nachzwirnmaschine gleichzeitig an einer größeren Spulenzahl durchführen läßt.The operation of removing the volatile treating agent by evaporation, be it by Passing over hot surfaces or by passing the treated material through a hot one Air flow or infrared radiation, is of particular importance in the finishing of threads, because the process is conveniently carried out on a correspondingly modified post-twisting machine at the same time can carry out a larger number of bobbins.

Die Fäden werden nach der Walze über zwei 20 cm lange Bügeleisen geleitet, von denen das erste auf 270 bis 280° C, das zweite auf 260 bis 270° C geheizt ist, und dann mit einer Maschine ausgespult.

The threads are following the roller passed over two 20 cm long irons, the first of which to 270 to 280 ° C, the second to 260 to 270 ° C, and then unwound with a machine. Threads treated in this way can be mixed with disperse dyes Stain well without carrier at 95 ° C.

Sie zeigen nach der Veredlung noch einen Thermoschrumpf von 3,5 °/o gegenüber einen Ausgangsschrumpf von 8,0 °/o. Die Steifheit der Fäden hat sich nur minimal erhöht.After finishing, they still show a thermal shrinkage of 3.5% compared to an initial shrinkage of 8.0 ° / o. The stiffness of the threads has only increased minimally.
