KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Es ist bekannt, Baumwolle, Zellulosewolle oder Zellulose unter Anwendung von Schwefelsäure auf kunstlederartige Stoffe zu verarbeiten. Auch ist es bekannt, Wolle teilweise zu lösen und durch Pressen in künstliches Leder überzuführen. Endlich ist es bekannt, Filz oder verfilztes Gewebe mit Steinkohlenteer und ungelöschtem Kalk zu tränken, dabei eine Anstrichmasse aus Leim, Essigsäure, venetianischem Terpentin, Zucker und Spiritus zu gleichem Zweck zu verwenden.It is known to use cotton, cellulose wool or cellulose with the use of sulfuric acid to process on synthetic leather-like fabrics. It is also known to partially add wool loosen and press into artificial leather. Finally it is known felt or to soak matted fabric with coal tar and unslaked lime, while doing so a paint made from glue, acetic acid, Venetian turpentine, sugar and alcohol to use for the same purpose.
Demgegenüber besteht vorliegende Erfindung dem Wesen nach darin, daß ausschließlich verfilzbare tierische Gespinstfasern in losem oder zubereitetem Zustande behandelt, und zwar im ganzen angequellt, an der Oberfläche aber in Lösung bzw. in einen der Verfilzung ähnlichen Zustand übergeführt werden. Die Gespinstfasern werden zu diesem Zweck in verdünnter Schwefelsäure o. dgl. bei einem Wärmegrad von ungefähr 96° C gekocht.In contrast, the present invention is essentially that exclusively treated entangled animal fibers in a loose or prepared state, and Although it has swelled as a whole, on the surface it is in solution or in one of the matting similar condition to be transferred. The roving fibers are used for this purpose in diluted sulfuric acid or the like. Boiled at a heat level of about 96 ° C.
Aus der durch die Lösung bzw. teilweise Verfilzung sich bildenden dicken Masse ergibt sich ein natürlicher Klebstoff, welcher zusammen mit dem durch das Anquellen hervorgerufenen Innendruck ein Zusammenhaften und Zusammenpressen der Fasermasse bewirkt, deren Dichte durch nachfolgende Pressung erforderlichenfalls gesteigert werden kann. From the thick mass formed by the solution or partly matting a natural adhesive, which together with that caused by the swelling Internal pressure causes the fiber mass to stick together and compress, the density of which can, if necessary, be increased by subsequent pressing.
Außerdem wird noch ein ebenfalls nahezu siedendes Gemisch aus Leim, Harz, venetianischem Terpentin und Bleiglanz benutzt, das von Fall zu Fall derart zusammengestellt wird, daß sich sein spezifisches Gewicht dem des zu behandelnden Stoffes gleichstellt. Dieses Kochen hat den Zweck, daß sich die Fasern mit der beschriebenen Flüssigkeit imprägnieren, wodurch die Faserfestigkeit gesteigert wird, ohne daß die Geschmeidigkeit der behandelten Fasermasse vermindert würde.In addition, there is a mixture of glue, resin, Venetian, which is also almost boiling Turpentine and galena are used, which is compiled from case to case in such a way that its specific gravity changes equates to that of the substance to be treated. The purpose of this cooking is that the Impregnate fibers with the liquid described, which increases the fiber strength is without the pliability of the treated fiber mass would be reduced.
Als Beispiel diene, daß Kalbshaare in ι: 300 Raumteilen verdünnter Schwefelsäure bei 960C ungefähr 12 bis 16 Stunden lang gekocht und nachher in beliebiger Form vorgepreßt werden. Die erhaltene Masse ist bis zur Vorpressung mit der nahezu kochenden verdünnten Schwefelsäure andauernd angenäßt zu halten. Der Preßling wird nun getrocknet und in ein Gemisch gelegt, welches in drei Teilen wie folgt hergestellt wurde:Serve as an example that veal hair is boiled in ι: 300 parts by volume of dilute sulfuric acid at 96 0 C for about 12 to 16 hours and then pre-pressed in any shape. The mass obtained must be kept soaked until it is pre-pressed with the almost boiling dilute sulfuric acid. The compact is now dried and placed in a mixture which was prepared in three parts as follows:
Zunächst werden 1,5 Gewichtsteile Harz mit 4 Gewichtsteilen venetianischem Terpentin unter langsamer Zugabe von 2,5 Gewichtsteilen Bleiglanz und unter stetiger Rührung verschmolzen. Dann werden 6 Gewichtsteile Leim in 4 Gewichtsteile Wasser eingeweicht und besonders aufgekocht. Endlich werden 4 Gewichtsteile venetianischen Terpentins allein geschmolzen.First, 1.5 parts by weight of resin are mixed with 4 parts by weight of Venetian turpentine with the slow addition of 2.5 parts by weight of galena and with constant stirring merged. Then 6 parts by weight of glue are soaked in 4 parts by weight of water and especially boiled. Finally there are 4 parts by weight of Venetian turpentine alone melted.
Der zuletzt erwähnte Terpentin wird mit dem besonders aufgekochten Dickleim vermischt und das Ganze mit dem zuerst vor-The last mentioned turpentine is mixed with the specially boiled thick glue and the whole thing with the first
bereiteten Gemisch verrührt. Das gemeinsame Gemisch wird bei einem langsamen Feuer zubereitet und sodann beinahe bis zum Kochen gebracht. Der Preßling wird in diesem heißen Gemisch ungefähr 48 Stunden lang belassen, dann nachgepreßt und fertiggetrocknet.prepared mixture stirred. The common mixture is made on a slow fire prepared and then brought almost to a boil. The pressed part is called in this one Leave the mixture for about 48 hours, then re-press and finish drying.
Man regelt das spezifische Gewicht des Gemisches am einfachsten mit der Verdünnung bzw. Eindickung des Kochleimes.The easiest way to regulate the specific weight of the mixture is to use the dilution or thickening of the cooking glue.
Das Verfahren ergibt eine wie zusammengeschmolzene, dicke, jedoch elastische Masse, welche eine Zeitlang beliebig geformt werden kann, dann aber, wie das Kunstleder, fest wird und eine wasserdichte Oberfläche zeigt. Die Fasern selbst lassen sich darin einzeln weder unterscheiden noch aus dem Endprodukt herausziehen; die Festigkeit der behandelten Gewebe usw. wird daher gegen den Anfangszustand bedeutend gesteigert.The process results in a fused, thick, but elastic mass, which can be shaped as desired for a while, but then, like artificial leather, solid and shows a waterproof surface. The fibers themselves can be separated in it neither distinguish nor extract from the end product; the strength of the treated Tissue, etc. is therefore significantly increased from the initial state.
