Description
Verfahren zum Schützen von Leder, Häuten, Geweben u. dgl. während ihrer Verarbeitung zu Verkaufsgegenständen unter Verwendung eines Schutzhäutchens Fabrikate aus Leder, Häuten, Fellen, Lederimitation, Geweben, Stoffen o. dgl., wie sie in der Saffianbereitung, in der Schuhwerksfabrikation und in verwandten Industrien verwendet werden, sind während ihrer Verarbeitung, Behandlung, Handhabung und maschinellen oder manuellen Formgebung (Fassonierung) Beschädigungen, Verschmutzungen und Überhaupt einer Verschlechterung unterworfen, die fast unmöglich vermieden werden kann. Dieser Nachteil macht sich besonders bei Leder, Häuten, Fellen, Stoffen usw. von lichter oder weißer Farbe fühlbar, die ihre ursprüngliche frische Farbe oder Reinheit nicht mehr wiedergewinnen, was immer man auch zu diesem Zweck versuchen mag.Method for protecting leather, hides, fabrics and the like during their processing into sales items using a protective membrane Products made of leather, hides, skins, imitation leather, fabrics, fabrics or the like, such as they are used in the preparation of saffron, in the manufacture of footwear and in related industries are used during their processing, treatment, handling and machine or manual shaping (shaping) damage, soiling and in general subject to deterioration that is almost impossible to avoid. This The disadvantage is especially with leather, hides, skins, fabrics, etc. of light or white color palpable that is not its original fresh color or purity to regain more, whatever one may try for that purpose.
Es sind bereits mehrere Mittel angegeben, um dem genannten Nachteil abzuhelfen. In der Mehrzahl bestehen sie darin, auf den in Frage kommenden Stoffen eine vorläufige Schutzschicht aufzubringen, die nach beendigter Verarbeitung des Stoffes wieder entfernt wird. So hat man vorgeschlagen, auf dem zu schützenden Leder eine Schutzmasse ,aufzutragen, die aus einem Bindemittel besteht, dem so viel eines pulverförmigen, anorganischen Stoffes beigemischt wird. daß der trockene Überzug verhältnismäßig leicht zerreibbar ist. Trotzdem erfordert das endgültige Entfernen dieses Überzuges eine sehr energische mechanische Einwirkung.Several means have already been given to overcome the disadvantage mentioned to remedy. In the majority, they consist in the substances in question to apply a temporary protective layer that will be applied after processing of the Material is removed again. So it has been suggested on the leather to be protected to apply a protective mass, which consists of a binding agent that is so much one powdered, inorganic substance is added. that the dry coating is relatively easily friable. Even so, it requires permanent removal this coating is a very energetic mechanical action.
Ferner ist vorgeschlagen worden, auf das Leder eine Lösung von Gelatine in Wasser oder von Celluloid in einem geeigneten Lösemittel aufzubringen. Das auf diese Weise erhaltene Schutzhäutchen haftet aber stark an und kann nur mittels eines Lösemittels wieder entfernt werden. Nach einem weiteren Vorschlag schaltet man zwischen dem zu schützenden Leder und der Firnisschicht einen staubförmigen Stoff ein, der das Anhaftungsvermögen verringert. Aber auch dieser pulverförmige Stoff ist schwer zu entfernen.It has also been proposed to apply a solution of gelatin to the leather to be applied in water or from celluloid in a suitable solvent. That on Protective membrane obtained in this way adheres strongly and can only be achieved by means of one Solvent can be removed again. After another suggestion, you switch between the leather to be protected and the varnish layer a dusty substance that the adhesion decreased. But this powdery substance is also heavy to remove.
Gemäß der Erfindung verringert man das Anhaftungsvermögen ' des Schutzhäutchens auf das unbedingt notwendige Maß, indem man der Lösung, aus der sich das Häutchen bilden soll, eine große Merlge eines plastisch machenden Mittels hinzufügt.According to the invention, the adherence of the protective membrane is reduced to the strictly necessary level by removing the solution that made up the membrane should form, adding a large amount of plasticizing agent.
Handelt es sich darum, eine poröse Haut oder ein Gewebe zu schützen, so befeuchtet man vorher die Oberfläche dieses Stoffes mittels eines Fällungsmittels oder eines Mittels. das den Firnis, aus dem sich das Schutzhäutchen bildet. nicht löst. Unter diesen Bedingungen kann das Häutchen leicht dadurch entfernt werden, daß man es in großen Stücken von Hand abzieht.When it comes to protecting a porous skin or tissue, so the surface of this substance is moistened beforehand by means of a precipitant or a means. that is the varnish from which the protective membrane is formed. not solves. Under these conditions the cuticle can easily pass through it removed by pulling it off by hand in large pieces.
Als Überzug können beispielsweise plastische Häutchen verwendet werden, die aus Celluloseazetat, Nitrocellulose, Benzylcellulöse o. dgl. bestehen und mittels verschiedener organischer Lösungsmittel oder mittels Kampfer, Rizinusöl usw. in plastischen Zustand überführt worden sind.Plastic skins, for example, can be used as a coating, which consist of cellulose acetate, nitrocellulose, benzyl cellulose or the like and means various organic solvents or using camphor, castor oil, etc. in plastic state have been transferred.
Ebenso lassen sich dünne Blättchen aus Guttapercha, Kautschuk oder gummihaltige Überzüge usw. verwenden.Thin leaflets made of gutta-percha, rubber or Use rubber-based coatings, etc.
Bei Verwendung celluloseartiger plastischer Stoffe bewirkt man das Anhaften des Überzuges entweder durch teilweises Lösen und durch Kalandern (Aufwalzen) des plastischen Stoffes oder durch Kalandern in der Wärme (Warmwalzen) oder auch durch direktes Aufgießen. Bei porösen- Körpern läßt sich ein zu starkes Anhaften :des Häutchens dadurch verhüten, daß matt beispielsweise die durch Überzug zu schützende, poröse Oberfläche vorher mit Benzin oder einem anderen die das Häutchen bildende Lösung nicht lösenden oder fällenden Mittel befeuchtet, wodurch das Eindringen der das Häutchen bildenden Lösung in die Poren des zu schützenden Gegenstandes verhindert wird.This is achieved by using cellulosic plastic materials Adhesion of the coating either by partial loosening and by calendering (rolling on) of the plastic material or by calendering in the heat (hot rolling) or also by pouring on directly. In the case of porous bodies, the adherence can be too strong : prevent the skin by matting, for example, the porous surface beforehand with gasoline or another which forms the membrane Solution non-dissolving or precipitating agent moistened, preventing the penetration of the prevents the pellicle-forming solution into the pores of the object to be protected will.
Besteht der Schutzüberzug aus einem Guttaperchablättchen, so genügt es, das Blättchen derart aufzuwalzen (kalandern), daß ein genügendes, jedoch nicht allzu starkes Haften bewirkt wird.If the protective coating consists of a gutta-percha plate, it is sufficient it is to roll (calender) the leaflet in such a way that a sufficient, but not too strong adhesion is caused.
Alle diese Überzüge oder Häutchen werden auf der Oberseite oder Schönseite des zu schützenden Teiles aufgetragen, d. h. auf jener Seite, die bei der Fertigware sichtbar ist.All of these coatings or skins are on the top or beautiful side applied to the part to be protected, d. H. on the side with the finished product is visible.
