Description

Verfahren zum Imprägnieren von Fasermaterial Es wurde gefunden, daß man Fasermaterial, wie Holz, Leder, Papier, Pappe, Textilgewebe oder faserhaltige Kunststoffe, sehr gut wasser-, öl- und benzinfest imprägnieren kann, wenn man es mit linearen wachsartigen Polyestern tränkt.Process for impregnating fibrous material It has been found that one fiber material such as wood, leather, paper, cardboard, textile fabric or fiber-containing Plastics can be impregnated very well with water, oil and petrol if you can soaked with linear waxy polyesters.

Solche Polyester werden z. B. aus Phosgen und zweiwertigen Alkoholen, wie Äthylen-, Propylen- oder Butylenglykol, erhalten. Andere geeignete Polyester kann man durch stufenweises Verestern von Dicarbonsäuren oder deren Derivaten mit zweiwertigen Alkoholen herstellen, gegebenenfalls unter Mitverwendung von Monooxyverbindungen und bzw. oder Monocarbonsäuren in der ersten und bzw. oder letzten Veresterungsstufe.Such polyesters are z. B. from phosgene and dihydric alcohols, such as ethylene, propylene or butylene glycol obtained. Other suitable polyesters can be done by gradual esterification of dicarboxylic acids or their derivatives with Prepare dihydric alcohols, optionally with the use of monooxy compounds and / or monocarboxylic acids in the first and / or last esterification stage.

Lineare Polyester der genannten Art sind in ihrer äußeren Beschaffenheit den natürlichen Wachsen so ähnlich daß ihre weitgehende oder völlige Unlöslichkeit in Ölen und Benzinkohlenwasserstoffen und ihre Verwendbarkeit zum Öl- und Benzinfestimprägnieren von Faserstoffen überrascht.Linear polyesters of the type mentioned are in their external nature so similar to natural waxes that they are largely or completely insoluble in oils and petrol hydrocarbons and their usability for solid impregnation with oil and petrol surprised by fiber.

Die Imprägnierung kann in der üblichen Weise durch Tränken des Fasermaterials mit den geschmolzenen Polyestern, erforderlichenfalls unter Verwendung von Vakuum oder von erhöhtem Druck, erfolgen. Gefäße aus Fasermaterial, z. B. aus Papier oder Pappe, kann man am einfachsten durch Ausgießen mit möglichst hoch erhitztem und daher dünnflüssigem Polyester wasser-, benzin- und ölfest machen.The impregnation can be carried out in the usual way by soaking the fiber material with the molten polyesters, using vacuum if necessary or by increased pressure. Vessels made of fiber material, e.g. B. made of paper or cardboard, the easiest way to pour it with if possible make highly heated and therefore low viscosity polyester water, petrol and oil resistant.

Es ist auf diese Weise möglich, aus nichtmetallischen Werkstoffen nicht nur wasser-, sondern auch benzin- und ölfeste Behälter, z. B. für Lederfette, Bohnermassen, Schuhkreme, Pomaden oder kosmetische Artikel, oder benzinfeste Dichtungen herzustellen.It is possible in this way to use non-metallic materials not only water, but also petrol and oil resistant containers, z. B. for leather grease, Floor polishes, shoe polishes, pomades or cosmetic articles, or petrol-proof seals to manufacture.
