Verfahren zum Imprägnieren von pflanzlichen, tierischen und mineralischen Faser- stoffen, Garnen und Geweben.
EMI1.1
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 trocknen Körper dar. Versuche, die Gerbstoffe durch chemische Behandlung oder Elektrolyse von der Leimsubstanz der Lösung zu trennen, schlugen fehl. Die dunkelbraune Leder-oder Gerbleimlösung
EMI1.2
zersetzt sich unter Ammoniakentwicklung.
Neutralisiert man dagegen die dunkelbraune Lederlösung (Gerbleimlösung) in geeigneter Weise, so wird dieselbe gut haltbar. Diese Neutralisation kann entweder mit verdünnten Säuren in vorsichtigel
Weise eifolgen oder mit Kohlensäure oder durch Zugabe von Fettsäuren, gehärteten Fettsäuren, Fetten, Ölen. Harzen, Zellpech und ähnlichen Stoffen in die kochende Gerbleimlösung, bis zu deren Neutralisation durch Verseifung des Alkalis mit den zugesetzten Substanzen.
Es hat sich nun gezeigt, dass diese braunen Leder (Gerbleim) lösungen sowohl im basischen als auch neutralisierten Zustande durch Zusatz von Säuren oder von neutralen, oder sauren, oder basischen
Salzen und auch von einigen Basen anorganischer und organischer Natur gefällt werden und ein wassel- unlöslicher Niederschlag von Leder entsteht, welcher sich wegen seiner wetterharten, wasserfesten und fäulniswidrigen Eigenschaften sehr gut zur Imprägnierung von pflanzlichen, tierischen und mineralischen
Fasern, Garnen eignet und ganz ausserordentlich billig ist.
Die Imprägnierung wird so ausgeführt, dass man beispielsweise Fischnetze, Waggondecken, Zeltbahnen, Verbandsbattiste, Taue durch die zweck- mässig heisse Gerbleim-Lederlösung zieht und sie dann, eventuell nach vorheriger Trocknung, in ein
EMI1.3
auf diese Art imprägnieren.
Nach Waschung und Trocknung kann dei Prozess beliebig wiederholt werden, bis die Faserstoffe vollständig mit Leder imprägniert sind, und dadurch wasser-und fäulnissicher geworden sind.
Solche mit Lederlösung imprägnierten Gewebe lassen, obwohl die Porösität voll gewahrt ist, Wasser nicht durch.
Zur Fällung der Lederlösung haben sich besonders Tonerdesalze, Aluminiumsulfat, Azetat und Alaun geeignet erwiesen, auch Eisenvitriol, Kupfersulfat, Kalziumchlorid und ähnliche Stoffe, aber auch organische Salze, Säuren und Basen.
Durch die deutsche Patentschrift 248.592 ist bekannt geworden ; dass man aus Lederalkalilösungen mit Alaun das Leder wieder ausfällen kann. Der feine, nass und heiss etwas plastische, trocken pulverige Niederschlag wird jedoch benützt, 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.
<Desc/Clms Page number 2>
Bei der vorliegenden Erfindung wird dagegen Faser, Garn oder Gewebe durch die Lederalkali- lösunggezogen und, nach Trocknung des zu imprägnierenden Materials, dieses dann in ein zweites Bad, ein Fällbad, gebracht, welches einen Lederniederschlag in und auf der Faser erzeugt, der durch Adsorption von der Faser festgehalten wird, und diese an sich völlig wasserfest imprägniert. Wenn man als Fällbad dabei vorzugsweise Tonerdesalze benutzt, so beruht dies auf der bekannten Eigenschaft dieser Salze, alle möglichen Stoffe, z. B. Farbstoffe, Harz und Ölseifen usw., auf der Faser zu fixieren.
Während man also nach der deutschen Patentschrift 248592 Fasermaterial mittels Lederniedei- schlag zu Presslingen verkittet und diese mit besonderen wasserdichtmachenden Mitteln wasserfest macht'0
EMI2.1
leinen, Waggondecken usw. vollständig wasserdicht gemacht, indem auf und in der Faser ein Lederriedersehlag erzeugt wird, wobei die Gewebestruktur vollständig erhalten bleibt und dessen Poren offen bleiben.
Feinere Battiste können, nach dem neuen Verfahren entsprechend bearbeitet, als Verbandesbattiste verwendet werden. Hiedurch wird dem Mangel, der den bisher gebräuchlichen. mit Öl getränkten Verbandsbattisten anhaftet und der darin besteht, dass diese Verbandsbattiste leicht brechen, wirksam abgeholfen.
Das neue Verfahren kann mit Vorteil auch dazu verwendet werden, um eine mit Leder imprägnierte Jute herzustellen, die man als Unterlage für Linoleum benutzen kann, wodurch der bisher erforderliche ganze Rückseitenfarbenanstrich (Ölfarbe) gespart werden kann.
Beispiele :
100 leg Lederabfallspäne werden in eine kochende Lösung von 1000 kg Wasser und 10 kg Ätznatron eingetragen und etwa eine Stunde gekocht bis das Leder vollständig aufgelöst ist. Die filtrierte Lösung wird nun neutralisiert.
Das Neutralisieren kann geschehen durch Einleiten von Kohlensäure oder Zugabe wässeriger verdünnter Säuren bis zum Verschwinden der Phenolphtaleinreaktion.
Die Neutralisation kann aber auch erfolgen durch Eintragen von Fetten, Ölen oder Harzen oder Fettsäuien in die kochende Lederlösung, wobei man ebenfalls kleine Portionen zusetzt und die Verseifung abwartet.
Der Stoff wird durch die neutralisierten heissen Lösungen gezogen und getrocknet und dies eventuell 2-3 mal wiederholt. Dann wird der Stoff durch ein heisses Fällbad (z. B. 100 kg Wasser 10 kg Aluminiumsulfat) gezogen, gewaschen und getrocknet.
PATENT-ANSPRÜCHE :
1. Verfahren zur Imprägnierung von pflanzlichen, tierischen und mineralischen Faserstofffen
Gamen und Geweben, dadurch gekennzeichnet, dass man die Faserstoffe abwechselnd in Bäder von mit Hilfe von Alkalien in Wasser gelöstem lohgaren Leder (Gerbleim) und solche wässerige Lösungen organischer und anorganischer Samen, Salze und Basen bringt, welche das Leder aus der Gerbleimlösung niedelschlagen und auf der Faser zu fixieren vermögen.

Process for the impregnation of vegetable, animal and mineral fibers, yarns and fabrics.
EMI1.1
contains the hide or glue substance as well as the tannins in dissolved form. When thickened, this solution turns into a dark brown jelly and in the solid state represents a brown-black, glossy, dry body. Attempts to separate the tannins from the glue substance of the solution by chemical treatment or electrolysis have failed. The dark brown leather or tanning solution
EMI1.2
decomposes with evolution of ammonia.
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 either be done with dilute acids in cautious
Either follow or with carbonic acid or by adding fatty acids, hydrogenated fatty acids, fats, oils. Resins, cell pitch and similar substances in the boiling tanning solution until it is neutralized by saponification of the alkali with the added substances.
It has now been shown that these brown leather (tanning) solutions both in the basic and neutralized state through the addition of acids or of neutral, or acidic, or basic
Salts and also some bases of inorganic and organic nature are precipitated and a water-insoluble deposit of leather is formed, which is very suitable for the impregnation of vegetable, animal and mineral due to its weather-hard, water-resistant and rot-resistant properties
Fibers, yarns are suitable and are extremely cheap.
The impregnation is carried out in such a way that, for example, fishing nets, wagon ceilings, tarpaulins, bandages, ropes are pulled through the suitably hot tanning leather solution and then, possibly after drying, in
EMI1.3
impregnate in this way.
After washing and drying, the process can be repeated as required until the fiber materials are completely impregnated with leather, and have thus become water- and rot-proof.
Such fabrics impregnated with leather solution, although the porosity is fully preserved, do not let water through.
Alumina salts, aluminum sulphate, acetate and alum have proven particularly suitable for precipitating the leather solution, as well as iron vitriol, copper sulphate, calcium chloride and similar substances, but also organic salts, acids and bases.
The German patent specification 248.592 made it known; that the leather can be precipitated again from leather alkali solutions with alum. The fine, wet and hot somewhat plastic, dry powdery precipitate is used, however, to fill fibrous leather waste or plant fibers and to cement them together, for the purpose of producing a compact, e.g. B. a shoe sole, wherein a waterproofing agent is added to make the compact waterproof.
<Desc / Clms Page number 2>
In the present invention, on the other hand, fiber, yarn or fabric is pulled through the leather alkali solution and, after the material to be impregnated has been dried, it is then brought into a second bath, a precipitation bath, which produces a leather precipitate in and on the fiber, which is absorbed by adsorption is held by the fiber, and this is completely waterproof impregnated. If alumina salts are preferably used as the precipitation bath, this is based on the known property of these salts, all possible substances, e.g. B. dyes, resin and oil soaps, etc. to fix on the fiber.
While, according to German patent specification 248592, fiber material is cemented into pellets by means of leather filings and these are made waterproof with special waterproofing agents'0
EMI2.1
Linen, wagon ceilings, etc. made completely waterproof by creating a Lederriedersehlag on and in the fiber, whereby the fabric structure is completely preserved and its pores remain open.
Finer battistes can be used as association battists after the new procedure has been processed accordingly. This eliminates the defect that has hitherto been used. with oil-soaked union batiste sticks and which consists in the fact that these union battists break easily, effectively remedied.
The new process can also be used with advantage to produce jute impregnated with leather, which can be used as a base for linoleum, which saves the entire reverse side paint (oil paint) previously required.
Examples:
100 leg leather waste shavings are added to a boiling solution of 1000 kg water and 10 kg caustic soda and boiled for about an hour until the leather is completely dissolved. The filtered solution is now neutralized.
Neutralization can be done by introducing carbonic acid or adding dilute aqueous acids until the phenolphthalein reaction disappears.
The neutralization can also be carried out by adding fats, oils or resins or fatty acids to the boiling leather solution, adding small portions and waiting for saponification.
The fabric is drawn through the neutralized hot solutions and dried, and this is repeated 2-3 times if necessary. The fabric is then drawn through a hot precipitation bath (e.g. 100 kg of water 10 kg of aluminum sulfate), washed and dried.
PATENT CLAIMS:
1. Process for the impregnation of vegetable, animal and mineral fibers
Gamen and fabrics, characterized in that the fibrous materials are alternately placed in baths of tanned leather (tannin) dissolved in water with the help of alkalis and aqueous solutions of organic and inorganic seeds, salts and bases which precipitate the leather from the tanning solution and open it able to fix the fiber.
