Geformte Gebilde aus hochpolymeren linearen Polyestern aus mehrbasischen Säuren und mehrwertigen Alkoholen, insbesondere aus sechsgliedrige Carbocyclen enthaltenden Polyestern, ζ. B. des Polyäthylenterephthalattyps, wie z. B. Fasern und Folien, besitzen eine sehr dichte innere Struktur, wenn sie einem Reckungsvorgang unterworfen wurden. Dies zeigt sich z. B. darin, daß sich derartige Materialien unter Bedingungen, wie sie bei der Anwendung von Dispersionsfarbstoffen in der Acetatseidenfärberei üblich sind, nicht oder kaum anfärben lassen.Molded structures made of high polymer linear Polyesters from polybasic acids and polyhydric alcohols, in particular from six-membered carbocycles containing polyesters, ζ. B. of the polyethylene terephthalate type, such as B. fibers and films, have a very dense internal structure when they were subjected to a stretching process. This is shown e.g. B. is that such materials under conditions such as those found in the use of disperse dyes in acetate silk dyeing are common, do not or can hardly be stained.

Ein Verfahren zur Färbung hochpolymerer PoIymethylenterephthalate mit Acetatseiden-Dispersionsfarbstoffen besteht darin, die Färbung in Gegenwart von Quellmitteln, sogenannten Carriers, durchzuführen (britische Patentschriften 609 943 bis 609 948). Die Quellmittel werden dabei in wäßriger Lösung oder Dispersion angewendet. Sie können den Färbeflotten zugesetzt werden, man kann jedoch auch die hochpolymeren Polymethylenterephthalate vor dem anschließenden Färben mit den Quellmitteln in wäßriger Flotte behandeln. Im allgemeinen wird das Carrier-Verfahren bei erhöhten Temperaturen bis 100° C durchgeführt. Die Arbeitsweise hat vor allen Dingen den Nachteil, daß infolge des Arbeitens in wäßriger Lösung die eingesetzten Verbindungen in hohen Konzentrationen angewendet werden müssen, um wirksam zu sein. Infolge ihrer Flüchtigkeit, insbesondere mit Wasserdampf, treten während des Färbeoder Vorbehandlungsprozesses erhebliche Verluste an wirksamer Substanz auf, die besondere Maßnahmen während der Behandlung erforderlich machen. Durch die infolge des Abdestillierens der Verbindungen auftretenden Geruchsbelästigungen ist man gezwungen, in besonderen Apparaturen oder unter Anwendung besonderer Schutzmaßnahmen zu arbeiten.A process for coloring high polymer polymethylene terephthalates with acetate silk disperse dyes is to carry out the dyeing in the presence of swelling agents, so-called carriers (British patents 609,943 to 609,948). The swelling agents are in an aqueous solution or dispersion applied. They can be added to the dye liquors, but you can also use the high-polymer polymethylene terephthalate before the subsequent dyeing with the swelling agents in aqueous Handle fleet. In general, the carrier process is carried out at elevated temperatures of up to 100 ° C carried out. The main disadvantage of this mode of operation is that as a result of working in aqueous solution the compounds used must be applied in high concentrations, to be effective. Due to their volatility, especially with water vapor, occur during dyeing or Pretreatment process significant losses of active substance on the special measures make necessary during treatment. By the occurring as a result of the distillation of the compounds Unpleasant odors are forced to use special equipment or use special protective measures to work.

Aus den britischen Patentschriften 697 983 bis 697 986 sind ferner Verfahren zur Verbesserung der färberischen Eigenschaften von Fasern oder Geweben aus Polyesterfasern bekanntgeworden, bei denen das Textilmaterial mit wäßrigen Lösungen von anorganischen Verbindungen, wie Zinkchlorid oder Lithiumbromid, oder auch mit Sulfurylchlorid behandelt wird. Die Substanzen bewirken einen oberflächlichen Angriff und eine Aufrauhung der Faser. Bei diesen Verfahren tritt jedoch eine starke hydrolytische Schädigung der Fasern ein, die mit einem Gewichtsverlust des Materials verbunden ist. Die angewendeten Verbindungen müssen durch einen zusätzlichen Waschprozeß vor dem Färben wieder entfernt werden. Da bei den Verfahren relativ hochkonzentrierte Lösungen angewendet werden, entstehen laufend Verfahren zur VeränderungFrom the British patents 697 983 to 697 986 are also methods for improving the dyeing properties of fibers or fabrics made of polyester fibers become known, in which the Textile material with aqueous solutions of inorganic compounds, such as zinc chloride or lithium bromide, or treated with sulfuryl chloride. The substances cause a superficial Attack and roughening of the fiber. In these processes, however, a strong hydrolytic effect occurs Damage to the fibers, which is associated with a weight loss of the material. The applied Compounds must be removed again by an additional washing process before dyeing. Since relatively highly concentrated solutions are used in the process, they are created continuously Procedure for change

For high temperature dyeing, however, are special equipment is required so that this method cannot be used everywhere.

Weiterhin ist es aus der britischen Patentschrift 684 046 bekannt, Polyesterfäden einen gewissen Schraumpf zwecks Verbesserung der Anfärbbarkeit zu verleihen, indem man die Fäden einer Hitzebehandlung bei Temperaturen zwischen 230 und 255° C unterwirft. Für die Wärmeübertragung wird die Verwendung inerter Flüssigkeiten, beispielsweise geschmolzener Metalle, geschmolzener Salze oder Kerosen empfohlen. Anstelle der Flüssigkeiten kann eine Infrarotbestrahlung oder eine andere der Wärmeübertragung dienende äquivalente Maßnahme dienen.It is also known from British patent specification 684 046, polyester threads a certain To improve the dyeability of the threads by heat treatment subjected to temperatures between 230 and 255 ° C. For heat transfer is the use of inert liquids, for example molten metals, molten salts or Kerosene recommended. Instead of the liquids, infrared radiation or another of the Serve heat transfer serving equivalent measure.

The temperature can be significantly higher than the melting temperature of the material. The upper limit is formed by the temperature at which charring and decomposition phenomena occur on the material surface. In general, the treatment temperature is between about 200 ° C, preferably about 220 0 C, and then 350 ° C, where it has been found to be particularly advantageous in case of temperature

assumed by increasing the temperature below the washing bath, which can reduce the treatment time for washing out the treatment if the detergent contains a suitable washing solution. This is followed by a cold water bath for quenching the formed structures at temperatures above 200 ° C., in particular above 220 ° C., preferably in the case of fibers. In order to achieve the required short contact time of temperatures which are close to the melting point of the polymer and the treatment bath, the material to be treated is selected to be short of immersion length with such chemical 35, for example substances that are between 0.5 and 10 cm under the process conditions. The withdrawal speed has a swelling effect without reacting with the polyesters - it is selected to be correspondingly high. It fluctuates within a short time in such a way that these are generally between about 50 and 2000 m.Unual substances only penetrate the surface of the treatment method an immersion distance in the size good, but the interior of the material 30 order of 0 , 5 to 2 cm in the case of which is preferred to remain untouched. use given temperature ranges and the take-off speed swelling under the process conditions between about 500 and active compounds that choose with the polyester 1200 m per minute,

The colorability of 400 m per minute and an immersion distance is, however, extraordinarily increased by the treatment according to the invention of 1 cm by a bath heated to 282 ° C. The reaction time depends on dimethyl sebacate passed. The entrained on the one hand by the marriage ester used is stripped off with a suitable moisture-mixing compound or the mixture of connector strippers for high-speed spinning, and the endless threads, which are conditioned and on the other hand, from the reaction temperature, are removed in temperature before winding. In individual cases it can be quenched by a brief cold water bath. Easily identify and color these endless threads with a blue color between about 10 ^ 4 and 1 second when trying to measure.
