Description
Verfahren zur Herstellung von künstlichen Textilgebilden aus Lösungen von Zellulose oder anderen plastischen massen. . Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von künstlichen Textilgebilden, Spitzen, Stickereien u. dgl. aus Lösungen von Zellulose, Nitrozellulose, Viskose, Azetylzellulose usw. oder anderen plastischen Massen (Kasein, Fibrin, Maisin usw.) und besteht darin, daß die Lösung zwischen einer glatten Unterlage und den Gravierungen einer auf der Unterlage aufliegenden Walze hindurchgeführt und in der dabei erhaltenen Gestalt durch eine Fällflüssigkeit, mit der die gravierte Walze benetzt ist, oder durch Anwärmen der gravierten Walze zum Erstarren gebracht wird. Hierdurch ist es möglich, Gebilde von beliebiger Dicke herzustellen; außerdem ist die Fabrikation gegenüber Bekanntem dadurch verbilligt, daß nur eine gravierte Walze von geringem Durchmesser erforderlich ist, welche auch schnell ausgewechselt werden kann.Process for the production of artificial textile structures from solutions of cellulose or other plastic masses. . The invention relates to a process for the production of artificial textiles, lace, embroidery and the like from solutions of cellulose, nitrocellulose, viscose, acetyl cellulose, etc. or other plastic masses (casein, fibrin, maisin, etc.) and consists of that the solution between a smooth surface and the engravings on the Underlay resting roller passed through and in the shape obtained thereby by a precipitating liquid with which the engraved roller is wetted, or by Heating the engraved roller is caused to solidify. This makes it possible To produce structures of any thickness; besides, the fabrication is opposite Known cheaper because only one engraved roller of small diameter is required, which can also be exchanged quickly.
Man bedient sich beispielsweise zur Ausführung des Verfahrens der in der Zeichnung dargestellten Einrichtung.One uses, for example, to carry out the method of device shown in the drawing.
Die aus einer Gießvorrichtung x in dünner, den Hohllinien einer Walze 2 entsprechender Schicht auf die Oberfläche einer sich darunter im Sinne des Pfeiles I drehenden Trommel 3 aufgetragene Zelluloselösung gelangt zu der mit Tüll- bzw. Gewebestickereimustern o. dgl. gravierten Wälze 2, an der sich die Masse staut, um ununterbrochen. durch die Hohllinien in der Gravur als entsprechende Gebilde hindurchzufließen und gleichzeitig teilweise zu erstarren. Ein seitliches Abdrücken der Masse wird dadurch verhindert, daß seitlich von der Trommel 3 zwei die Gießvorrichtung x reit der Preßwalze 2 verbindende Flügel 4 angegeordnet sind. Das genügend fest gewordene Produkt wird nun auf der Oberfläche der Trommel 3 weitergeführt, taucht erforderlichenfalls in die Härtungsflüssigkeit eines Behälters 5 in dem die Trommel 3 gelagert ist, und wird schließlich durch Walzen 6, 7 abgezogen und in mehreren angepaßten, sich in Behältern 8, g und xo befindlichen Waschflüssigkeiten, wobei es mittels Walzen 1z, 12, 13, 14, 15, 16 geführt wird, ununterbrochen nachbehandelt (z. B. weiter ausgefällt, gesäuert, gewaschen usw.) und auf einer Spule 17 aufgewickelt.The from a casting device x in thinner, the hollow lines of a roller 2 corresponding layer on the surface of one below in the direction of the arrow Cellulose solution applied to the rotating drum 3 reaches the Fabric embroidery patterns or the like engraved rollers 2, on which the mass accumulates, around continuously. through the hollow lines in the engraving as corresponding structures to flow through and at the same time partially solidify. A side print the mass is prevented that the side of the drum 3 two the casting device x rides the press roll 2 connecting wings 4 are arranged. That firm enough The product that has become is now carried on to the surface of the drum 3, immersed if necessary in the hardening liquid of a container 5 in which the drum 3 is stored, and is finally drawn off by rollers 6, 7 and in several adapted washing liquids located in containers 8, g and xo, wherein it is guided by means of rollers 1z, 12, 13, 14, 15, 16, continuously post-treated (e.g. further precipitated, acidified, washed, etc.) and wound up on a spool 17.
Es wurde nun die Beobachtung gemacht, daß sich die künstlichen Gebilde nicht leicht von den eingravierten Hohllinien der Walze 2 ablösen, besonders nicht bei dickeren Stickereinachahmungen. Dieses Anhaften wird dadurch verhütet, daß man in die Hohllinien der Walze 2 aus Rohr 18 eine Fäll- oder Härtungsflüssigkeit - vor Durchführung der Lösung spritzt, den Überschuß auf der Walzenoberfläche hingegen durch Abstreifmesser z9 sorgfältig entfernt. Auch die Oberfläche der Trommel 3 muß ganz rein sein, bevor sie wieder zur Gießvorrichtung i gelangt, um eine neue Zelluloseschicht aufzunehmen. Dies erreicht man durch einen der Trommeloberfläche angepaßten Kasten 2o mit seitlichem Ablauf 21, in welchen eine das vorhergehende Fällbad neutralisierende Waschflüssigkeit durch das Rohr 22 eingeführt wird.The observation has now been made that the artificial structures not easily peeled off from the engraved hollow lines of roller 2, especially not with thicker embroidery imitations. This clinging is prevented by one in the hollow lines of the roller 2 from tube 18 a precipitation or hardening liquid - splashes before carrying out the solution, the excess on the roller surface, however carefully removed by scraper knife z9. Also the surface of the drum 3 must be completely clean before it gets back to the casting device i for a new one Take up cellulose layer. This is achieved through one of the drum surfaces adapted box 2o with side drain 21, in which one the previous Washing liquid neutralizing the precipitation bath is introduced through the tube 22.
Wie aus der Zeichnung ersichtlich, wirkt der Rand dieses Kastens 2o zugleich als Abstreifvorrichtung, und eine zwischen dem Kasten 2o und der Gießvorrichtung angebrachte angewärmte Walze 23 trocknet die Oberfläche der Trommel 3.As can be seen from the drawing, the edge of this box acts 2o at the same time as a stripping device, and one between the box 2o and the pouring device attached heated roller 23 dries the surface of the drum 3.
Ein Ankleben der Gebilde in den Hohllinien kann auch dadurch verhindert werden, daß man die Walze 2 auf die erforderliche Temperatur erwärmt, um durch die Hitze eine Koagulierung der Gebilde hervorzurufen. Besondere Effekte lassen sich erzielen, wenn einheitlich oder verschieden gefärbter Faserstaub mit der Fällflüssigkeit in die Hohllinien der Walze 2 eingetragen wird, so daß diese Fasern beim Formen und gleichzeitigen Ausfällen der Masse an der Oberfläche der Gebilde anhaften und deren Aussehen und Griff entsprechend beeinflußen. Auch flüssiger Gummi, Talkum, Metallpulver usw. können zur Bildung der Oberflächenschicht des Produktes herangezogen werden.This can also prevent the structures from sticking in the hollow lines be that the roller 2 is heated to the required temperature to through the Heat to cause coagulation of the structures. Special effects can be achieve when uniformly or differently colored fiber dust with the precipitating liquid is entered into the hollow lines of the roller 2, so that these fibers during molding and simultaneous precipitation of the mass adhere to the surface of the structure and influence their appearance and feel accordingly. Also liquid rubber, talc, Metal powder, etc. can be used to form the surface layer of the product will.
