Verfahren zur Herstellung von Lederersatz.
Die Herstellung von Lederersatz beschränkt sich im allgemeinen darauf, dass man fertige Gewebe oberflächlich mit Firnissen behandelt, mit deren Hilfe ein lederartiges Aussehen erzielt werden kann.
Das vorliegende Verfahren wird auf fertige Garne oder fertige Gewebe aus Zelluloseestern angewandt und beruht mehr auf einem chemischen als einem mechanischen Prozess, indem die Aktivität der Zelluloseester für bestimmte chemische Reagentien heraugezogen wird, wodurch nicht nur ein lederartiges Aussehen, sondern auch eine stoffliehe Ledernachahmung entsteht.
Das Verfahren gemäss der Erfindung besteht darin, dass man Strang-oder Stoffbahnen mit
EMI1.1
Lederersatzes zu erhohen.
Beispiel :
5 kg Azetyleellulose in Form von Garn oder Stoff werden in einem Bade von 100 l 1%iger Tanninlösung während 2 Stunden bei 70-80 C umgezogen. Es folgt ein kurzes Waschen mit Rohwasser und ein
EMI1.2
gewaschen und auf dem Färbebad ausgefäibt. Nach dem Trocknen wird die Ware kalandriert und je nachBedürfnismiteinerAppreturlösungbehandelt.
Bei der technischen Anwendung des Verfahrens hat es sich namentlich gezeigt, dass Salze und Oxyde des Wismuts, des Zinks, des Silbers und des Eisens sich zu einem lederartigen Effekt günstig eignen, namentlich, da sie mit dem Zelluloseester nach dem beschriebenen Verfahren in chemische Verbindung zu treten vermögen.

Process for the production of leather substitutes.
The production of leather substitutes is generally limited to treating finished fabrics on the surface with varnishes, with the aid of which a leather-like appearance can be achieved.
The present method is applied to finished yarns or finished fabrics made of cellulose esters and is based more on a chemical than a mechanical process in that the activity of the cellulose ester for certain chemical reagents is drawn on, whereby not only a leather-like appearance but also a fabric-like leather imitation is created.
The method according to the invention consists in that one strand or fabric webs with
EMI1.1
Increase leather substitute.
Example:
5 kg of acetyl cellulose in the form of yarn or fabric are removed in a bath of 100 l of 1% tannin solution for 2 hours at 70-80 C. This is followed by a short wash with raw water and a
EMI1.2
washed and finished on the dye bath. After drying, the goods are calendered and treated with a finishing solution as required.
In the technical application of the process it has been shown that salts and oxides of bismuth, zinc, silver and iron are suitable for a leather-like effect, namely because they are chemically bonded to the cellulose ester according to the process described be able to step.
