Description

Verfahren zum Imprägnieren von pflanzlichen, tierischen und mineralischen Faserstoffen, Garnen und Geweben. Löst man loh-gare Lederabfälle in verdünnten, wässerigen Alkalien,* z. D. Natronlauge, Kalilauge, Soda, Ammoniak, Barytwasser usw., so erhalt man eine tiefbraune, klare Flüssigkeit, welche sowohl die Haut- oder Leimsubstanz als auch die Gerbstoffe gelöst enthält. Diese Lösung geht beim Eindicken in eine dunkelbraune Gallerte Über und stellt im festen Zustand einen braunschwarzen, glänzenden trocken-en Körper dar. Versuche, die Gerbstoffe durch chemische Behandlung oder Elektrolyse von der Leimsubstanz der Lösung zu trennen, schlugen fehl. Die dunkelbraune Leder- oder Gerbleimlösung ist an sich nicht sehr klebfähig; und' hält sich, nainentlich zur Gallerte eingedickt, nicht lange, sonderri zersetzt sich unter Ammoniakentwicklung.Process for impregnating vegetable, animal and mineral Fibers, yarns and fabrics. If you dissolve treacherous leather waste in diluted, aqueous alkalis, * e.g. D. Caustic soda, potassium hydroxide, soda, ammonia, barite water etc., a deep brown, clear liquid is obtained, which both the skin and or contains glue substance as well as the tannins dissolved. This solution works with Thicken into a dark brown gelatinous layer and, when solid, provides a brown-black, shiny dry body. Try to get the tannins through chemical treatment or electrolysis to separate the glue substance of the solution, Failed. The dark brown leather or tanning solution is not very much in itself adhesive; and 'does not last long, especially if it is thickened to a jelly, special decomposes with evolution of ammonia.

Neutralisiert man dagegen die dunkelbraune Lederlösung (Gerbleimlösung) in geeigneter Weise, so wird dieselbe gut haltbar. Diese Neutralisation kann entweder mit verdünnten Säuren in vorsichtiger Weise erfolgen oder mit Kohlensäure oder durch Zu-- ga be von Fettsäuren, gehärteten Fettsäuren, Fetten, ölen, Warzen, Zellpech und ähnlichen Stoffen in die kochende Gerbleimlösung bis zu deren Neutralisation durch Verseifung des Alkalis mit den zugesetzten Substanzen.If, on the other hand, the dark brown leather solution (tanning solution) is neutralized in a suitable manner, it can be kept well. This neutralization can be effected either with dilute acids in a conservative manner with carbon dioxide or by switching - ga be of fatty acids, hydrogenated fatty acids, fats, oils, warts, cell pitch and similar substances in the boiling Gerbleimlösung until their neutralization by saponification of the alkali with the added substances.

Es hat sich nun gezeigt, daß diese braunen, Leder- (Gerbleim) Lösungen sowohl im basischen als auch neutralisiertem Zustandejurch Zusatz von Säuren oder von neutralen oder saurien oder basischen Salzen und auch von einigen Basen anorganischer und organischer Natur gefällt werden und ein wasserunlöslicher Niederschlag von Leder entsteht, welcher sich wegen seiner wetterharten, wasserfesten und fäulniswidrigen Eigenschaften sehr gut zur Imprägnierung von pflanzlichen, ti-erischen und mineralischen Fasern, Garnen eignet und ganz außerordentlich billig isf. Die Imprägnierung wird so ausgeführt, daß man beispielsweise Fischnetze, Waggondecken, Zeltbahnen, Ernteplanen, Verbandsbatiste, und Taue durch die zweckmäßig heiße Gerbleirn-(Leder-) L-Ösung 7,iebt und sie dann, evtl. nach vorheriger Trocknung, in ein zweites Bad bringt, welches Säuren, Salze oder Basen enthält, die die Lederlösung fällen. und direkt auf der Faser einen Lederniederschlag :fixieren. Man. kann natürlich auch die Garne vor Ader Verwebung auf #diese Art imprägnieren.It has now been shown that these brown, leather (tanning glue) solutions both in the basic and in the neutralized state by adding acids or of neutral or acidic or basic salts and also of some inorganic bases and of an organic nature and a water-insoluble precipitate of Leather is created, which is because of its weather-hard, waterproof and rot-resistant Properties very good for impregnating vegetable, animal and mineral products Fibers and yarns are suitable and extremely cheap. The impregnation will designed in such a way that, for example, fishing nets, wagon ceilings, tarpaulins, harvest tarpaulins, Association batiste and ropes through the appropriately hot tanning (leather) solution 7, and then, possibly after drying, brings it to a second bath, which contains acids, salts or bases that precipitate the leather solution. and direct a leather deposit on the fiber: fix. Man. can of course also use the yarns Impregnate this way before weaving.

.Nach Waschung und! Trocknung kann der Prozeß beliebig wiederholt werden, bis die Faserstoffe vollständig mit Leder imprägniert sind und dadurch wasser- und, fäulnissicher geworden sind..After washing and! The drying process can be repeated as desired until the fibers are completely impregnated with leather and thus water- and, have become rot-proof.

Solche mit Lederlösung imprägnierten Gewebe lassen ' obwohl die Porösität.,voll gewahrt ist, Wasser nicht durch.Such impregnated leather tissue solution can not be 'even though the porosity is fully protected., By water.

Zur Fällung der Lederlösung haben sich besonders Tonerdesalze, Alum-iniumsulfat, -acetat und Alaun geeignet erwiesen, auch Eisenvitriol, Kupfersulfat, Calciumchlorid und ähnliche Stoffe, aber auch organische Salze, Säuren und Basen.Alumina salts, aluminum sulphate, -acetate and alum proved suitable, also iron vitriol, copper sulphate, calcium chloride and similar substances, but also organic salts, acids and bases.

Durch die deutsche Patentschrift 248592 ist bekannt geworden, daß man aus Lederalkalilösungen mit Alaun das Leder wieder ausfällen kann. Der feine, naß und heiß etwas plastisc.he, trocken pulverige 2\-iiederschlag wird je- doch benutzt, um faserige Lederabfälle oder Pflanzenfasern zu füllen und aneinander zu kitten, zum Zwecke, einen Preßling herzustellen, z. B. eine Schuhsohle, wobei man ein wasserdichtmachendes Mittel hinzufügt, um den Preßling wasserfest zu machen.The German patent specification 248592 has made it known that leather can be precipitated again from leather alkali solutions with alum. The fine, wet and hot something plastisc.he, dry powdery 2 \ -iiederschlag is JE yet used to fill fibrous waste leather or plant fibers and kitten together for the purpose of producing a compact, z. B. a shoe sole, adding a waterproofing agent to make the compact waterproof.

Bei der vorliegenden Erfindung wird dagegen Faser, Garn oder Gewebe durch die Lederälkalilösung gezogen und nach 'frocknung des zu imprägnieren-den Materials,dieses dann in ein zweites Bad, ein Fällbad, gebracht, welches ein-en Lederniederschlag in, und auf der Faser erzeugt, der durch Adserption; von der Faser festgehalten wird und diese an sich völlig wasserfest imprägniert. Wenn man als Fällbad dabei vorzugsweise Tonerdesalz#e benutzt, so beruht dies auf der bekannten Eigenschaft dieser Salze, alle möglichen Stoffe, z. B. Farbstoffe, Harz und ölseifen usw., auf der Faser zu fixier-en.In the present invention, on the other hand, fiber, yarn or fabric is used drawn through the leather oil solution and after drying of the to be impregnated Material, this is then brought into a second bath, a precipitation bath, which is a Deposits of leather in and on the fiber produced by adsorption; from the fiber is held and this is completely waterproof impregnated in itself. If you are a The precipitation bath preferably uses alumina salt, this is based on the known method Property of these salts, all possible substances, e.g. B. dyes, resin and oil soaps etc., to be fixed on the fiber.

Während man also nach der deutschen Patentschrift 248592 Fasermaterial mittels Lederniederschlag zu Preßlingen verkittet und diese mit besonderen -wasserdichtmachenden Mitteln wasserfest macht, werden durch die vorliegende Erfindung vorzugsweise Ggwebe, z. B. Segeltuche, Ernteplanen, Verdeckleinen, Waggondecken usw., vollständig wasserdicht gemacht, indern auf un,d# in der Faser ein Ledernied-erschlagerzeugt wird, wobei die Gewebestruktur vollständig erhalten bleibt und dessen, Poren offen bleiben.So while according to the German patent specification 248592 fiber material cemented into pressed pieces by means of leather precipitation and these with special waterproofing agents Makes water-resistant agents, the present invention is preferably Ggwebe, z. B. canvas, harvest tarpaulins, hoods, wagon covers, etc., completely waterproof made, while on un, d # in the fiber a leather deposition is produced, whereby the tissue structure is completely preserved and its pores remain open.

Feinere Batiste können, nach dem neuen Verfahren entsprechend bearbeitet, als Verbandsbatiste verwendet werden. Hierdurch wird dem Mangel, der den bisher gebräuch# lichen, mit öl getränkten Verbandsbatisten anhaftet, und der darin besteht, daß diese Verbandsbatiste leicht brechen, wirksam abgeholfen.Finer batiste can be used as association batiste after the new process has been processed accordingly. This effectively remedies the deficiency that adheres to the oil- soaked association batists that have been used up to now, and which consists in the fact that these association batists break easily.

B e i s p i c 1 e.For example p i c 1 e.

ioo kg Lederabfallspäne werden in eine kochende Lösung von iooo kg Wasser und ti io kg Ätznatron eingetragen und etwa eine Stunde gekocht, bis "das Leder vollständig aufgelöst ist. Die filtrierte Lösung wird nun neutralisiert.ioo kg waste leather shavings are added to a boiling solution of iooo kg of water and ti io kg of caustic soda and about boiled for one hour, until "the leather is completely dissolved. The filtered solution is now neutralized.

Das Neutralisieren kann geschehen durch Einleiten von Kohlensäure oder Zugabe wässeriger, verdünnter Säuren bis zum Verschwinden d#--r Phenolphtaleinreaktion.Neutralization can be done by introducing carbon dioxide or addition of aqueous, dilute acids until the phenolphthalein reaction disappears.

Die Neutralisation kann aber auch erfolgen durch Eintragen von Fetten, ölen oder Harzen oder Fettsäuren in die kochende Lederlösung, wobei man ebenfalls so lange kleine Portionen zusetzt und die Verseifung abwartet, his die Phenolphtaleinreaktion verschwindet.The neutralization can also be done by adding fats, oils or resins or fatty acids in the boiling leather solution, whereby one likewise add small portions and wait for the saponification until the phenolphthalein reaction disappears.

Der Stoff wird durch die neutralisierten heißen Lösungen gezogen und- getrocknet und k> el dies evtl. zwei- bis dreimal wiederholt. Dann wird der Stoff durch ein heißes Fällbad (z. B. ioo kg Wasser, io kg Aluminiumstilfat) ge-ZD zogen, gewaschen und getrocknet.The fabric is pulled through the neutralized hot solutions and-dried and k> el this possibly repeated two or three times. The fabric is then pulled through a hot precipitation bath (e.g. 100 kg of water, 10 kg of aluminum stilfate), washed and dried.
