Description

Verfahren zum Leimen von Hydratzellulose oder daraus hergestellten Gegenständen. Die Hydratzellulose ist bekanntlich ein Körper von großer Saugfähigkeit und Hygroskopizität. Ein aus Kunstseideabfällen hergestelltes Papier ist aus diesen Gründen nur schwer leimfest herzustellen.Process for sizing hydrate cellulose or produced therefrom Objects. The hydrate cellulose is known to be a body of great absorbency and hygroscopicity. A paper made from waste rayon is made from them Reasons difficult to glue.

Es wurde nun die Beobachtung gemacht, daß Hydratzellulose die Eigenschaft hat, lösliche, hydrolytisch spaltbare, basische Aluminium-, Chrom- und ähnliche Salze selbst aus verhältnismif>ig großer Verdünnung unter Säureabspaltung in die unlöslichen basischen Salze zu verwandeln und sich diese Salze anscheinend molekular anzulagern.It has now been observed that hydrate cellulose has the property has, soluble, hydrolytically cleavable, basic aluminum, chromium and the like Salts even from a relatively large dilution with elimination of acid in the to transform insoluble basic salts and these salts appear to be molecular to accumulate.

Durch diesen Vorgang werden sowohl die Saugfähigkeit als auch die Hygroskopizität der Hydratzellulose aufgehoben, und das Produkt wird leimfest, ohne daß die anderen Eigenschaften des Stoffes, wie Weichheit, Glanz usw., beeinträchtigt werden.This process increases both the absorbency and the The hygroscopicity of the hydrate cellulose is eliminated and the product becomes glue-resistant without that the other properties of the fabric, such as softness, luster, etc., adversely affect will.

Tränkt man ein aus Hydratzellulose hergestelltes Papier, welches hervorragend als Löschpapier geeignet ist, mit einer Lösung eines basisehen Tonerdeazetates vom spei. Gewicht i,oi, preßt ab und trocknet, so wird dieses Papier vollkommen leimfest. Um eine V olleimung im Holländer zu erhalten, genügt z. B. der Zusatz von i Prozent löslichen basischen Salzes zum Stoff.If you soak a paper made of hydrate cellulose, which is excellent is suitable as blotting paper, with a solution of a basic alumina acetate from spit. Weight i, oi, presses off and dries, so this paper becomes completely glue-proof. To get a full sizing in the Dutch, z. B. the addition of i percent soluble basic salt to the substance.

Es ist nun zwar bekannt, basische TonerdesalzIösungen von 6- Be und mehr zum M'asserdichtmachen von Geweben zu verwenden (H. Walland, Wasch-, Bleich- und Appreturmittel, igi3, S. 267). Die nach diesem Verfahren hergestellten gallertartigen Niederschläge machen aber weiche, glänzende Papiere aus Hydratzellulose trüb und hart, zum Teil sogar brüchig, da bei diesem Verfahren die Faser von unlöslichem basischen Tonerdeazetat eingehüllt wird.It is now known to use basic alumina salt solutions of 6- Be and to use more for waterproofing fabrics (H. Walland, Wasch-, Blleich- and Finishing Agents, igi3, p. 267). The gelatinous produced by this process However, precipitates make soft, glossy papers made of hydrate cellulose cloudy and hard, sometimes even brittle, since in this process the fibers are insoluble basic alumina acetate is enveloped.

Es ist einleuchtend, daß das neue Verfahren mit dem bei Walland beschriebenen absolut nicht identisch ist.It is evident that the new procedure should be compared with that described by Walland is absolutely not identical.

Das neue Verfahren läßt sich nicht nur zum Leimen von Papierstoff im Holländer und zum Nachleimen fertiger Papiere aus Hydr atzellulese anwenden, sondern es kennen auch alle Gegenstände aus Hydratzellulose durch eine entsprechende Behandlung geleimt werfen.The new process can not only be used for sizing paper stock use in the Dutch and for re-sizing of finished papers from hydration cellulese, but also know all objects made of hydrate cellulose through a corresponding one Throw treatment glued.
