     Wursthiillenmaterial   
Die Erfindung betrifft ein Wursthüllenmaterial.



   Es ist bereits bekannt, für Wursthüllen anstelle von Naturdärmen solche aus irgendwelchen synthetischen Materialien, darunter auch polymeren Kunststoffen, zu verwenden. Nun sind aber in der Regel die Schrumpfeigenschaften von reinen Kunststoffdärmen sehr schlecht. Beim Lagern oder Kochen von Würsten mit derartigen Hüllen wird das Brät geringe Volumänderungen erfahren. Wenn das Brät schrumpft, dann kann die Kunststoff-Folie nicht in demselben Ausmass mitschrumpfen. Die Hülle liegt dann nicht mehr prall an dem Wurstbrät an. Dies erweckt ein unansehnliches Aussehen.



   Ziel der Erfindung ist nun die Schaffung eines Wursthüllenmaterials, das immer eng am Wurstbrät anliegen kann. Das Wursthüllenmaterial sollte also gewissermassen elastische Eigenschaften aufweisen, die einer reinen Kunststoff-Folie fehlen.



   Das erfindungsgemässe Wursthüllenmaterial ist dadurch gekennzeichnet, dass es aus einem Faservlies besteht, das so mit Kollagen gebunden ist, dass die Konzentration des   Kollagenbindemitteis    über den Gesamtquerschnitt des Faservlieses hinweg zunimmt, und dass die kollagenarme Vlies oberfläche mit einer Kunststoff Folie verbunden bzw. mit einer Kunststoffschicht überzogen ist.



   An sich ist das Binden von Faservliesen mit einem sogenannten Kollagenfaserbrei bereits bekannt. Zu diesem Zweck wird ein loses Faservlies mit dem Kollagen Faserbrei imprägniert, getrocknet und einer Nachbehandlung unterworfen. Das Endprodukt kann als Syntheseleder verarbeitet werden. Entsprechende Verfahren sind beschrieben in  The Journal of the American Leather Chemists Association , Vol. LXIII, Nr.   1    Januar 1968 sowie den USA Patentschriften 3 063 892,   3071483,    3 073 714, 3 223 551, 3 269 851, 3 285 775,   3 294579,    3 294 581 und dem kanadischen   Patent    749 911.



   Bei der Herstellung dieser bekannten Materialien strebt man eine möglichst gleichförmige Verteilung von Fasern und Bindemittel (Kollagen) an.



   Erfindungsgemäss soll jedoch das Fasermaterial auf einer Oberfläche mit Kollagen angereichert sein. Es hat sich nämlich gezeigt, dass ein derart mit Kollagen gebundenes Vlies dem Wachsen und Schrumpfen des Wurstbrätes gut folgen kann.



   Beispiel
Zur Herstellung eines Wursthüllenmaterials schlämmt man z. B. ein Fasergemisch aus gleichen Teilen Zellwolle und Zellstoff in einem grossen Wasserüberschuss auf. Gleichzeitig enthält das Wasser Kollagen-Faserbrei.



  Dieses Gemisch wird dann auf einem Steilsieb angeschwemmt. Es hinterbleibt dann auf dem Sieb ein Faservliesgemisch mit einem Anteil von - je nach der zugegebenen Menge - 5 bis 10 % Kollagen. Am oberen Ende des Steilsiebes befindet sich dann nochmals ein Behälter mit einer Kollagendispersion. Man lässt nun diese Dispersion auf das darunterliegende Sieb auflaufen. Dabei reichert sich das Kollagen an der Oberfläche des bereits kollagenhaltigen Vlieses an. Der Wasserüberschuss wird in üblicher Weise abgesaugt.



   Anschliessend trocknet man das nasse Vlies, indem man es durch eine Trockenkammer laufen lässt oder über einen Trockenzylinder führt. Dabei tritt eine Verfestigung des Materials ein.



   Anschliessend muss das im Vlies vorhandene Kollagen noch gegerbt werden. Dies erfolgt in der einfachsten Weise dadurch, dass man das nunmehr mit Kollagen verfestigte Faservlies mit einer wässrigen, Aldehyde enthaltenden Lösung, vorzugsweise Glutaraldehyd, besprüht. Der Aldehyd gerbt dabei das Kollagen.



   Anschliessend erfolgt eine Beschichtung der kollagenarmen Seite mit einer Lösung von Polyvinylidenchlorid.



   Die mit Kollagen angereicherte Seite des so erhaltenen Wursthüllenmaterials kann sowohl quellen als auch  schrumpfen, wodurch ein enges Anliegen an der zu verpackenden Ware gewährleistet wird. Anderseits haftet das Polyvinylidenchlorid sehr gut an der kollagen armen Seite. Würde man es auf die mit Kollagen ange reicherte Seite aufbringen, so würde es sich ablösen. Das Polyvinylidenchlorid ist vollkommen wasserdampf- und luftundurchlässig, was für viele Anwendungen unbedingt erforderlich ist. An sich wäre auch ein Verpacken der
Ware mit einer reinen Polyvinylidenchloridfolie mög lich; verfertigt man aus einer solchen Folie einen Kunst darm, (nicht erfindungsgemäss), so wird dieser jedoch sehr schlecht an der Wurstmasse anliegen, es bilden sich
Falten und Runzeln, wodurch das Aussehen der Ware beeinträchtigt wird.

   Kombiniert man aber die Polyvinyl idenchloridfolie mit einem kollagengebundenen (und auf einer Seite angereicherten) Vlies der beschriebenen Art dann werden die Därme nach dem Füllen mit Wurstbrät immer prall am Brät anliegen. 



  
 



     Sausage sleeve material
The invention relates to a sausage casing material.



   It is already known to use sausage casings made of any synthetic materials, including polymeric plastics, instead of natural casings. As a rule, however, the shrinkage properties of pure plastic casings are very poor. When storing or cooking sausages with such casings, the sausage meat will experience slight changes in volume. If the sausage meat shrinks, the plastic film cannot shrink to the same extent. The casing then no longer lies tightly against the sausage meat. This creates an unsightly appearance.



   The aim of the invention is now to create a sausage casing material that can always lie close to the sausage meat. The sausage casing material should therefore to a certain extent have elastic properties that a pure plastic film lacks.



   The sausage casing material according to the invention is characterized in that it consists of a fiber fleece which is bound with collagen in such a way that the concentration of the collagen binding agent increases over the total cross-section of the fiber fleece, and that the non-woven surface that is poor in collagen is connected with a plastic film or with a plastic layer is covered.



   The binding of nonwovens with a so-called collagen fiber pulp is already known per se. For this purpose, a loose fiber fleece is impregnated with the collagen fiber pulp, dried and subjected to an after-treatment. The end product can be processed as synthetic leather. Corresponding processes are described in The Journal of the American Leather Chemists Association, Vol. LXIII, No. 1 January 1968 and the USA patents 3,063,892, 3071483, 3,073,714, 3,223,551, 3,269,851, 3,285,775, 3 294579, 3 294 581 and Canadian patent 749 911.



   When producing these known materials, the aim is as uniform as possible a distribution of fibers and binding agent (collagen).



   According to the invention, however, the fiber material should be enriched with collagen on a surface. It has been shown that a fleece bonded with collagen in this way can easily follow the growth and shrinkage of the sausage meat.



   example
To produce a sausage casing material, e.g. B. a fiber mixture of equal parts of viscose and cellulose in a large excess of water. At the same time, the water contains collagen pulp.



  This mixture is then washed ashore on a steep sieve. A fiber fleece mixture with a proportion of - depending on the amount added - 5 to 10% collagen then remains on the sieve. At the upper end of the steep sieve there is again a container with a collagen dispersion. This dispersion is now allowed to run onto the sieve below. The collagen accumulates on the surface of the already collagen-containing fleece. The excess water is suctioned off in the usual way.



   The wet fleece is then dried by running it through a drying chamber or passing it over a drying cylinder. A solidification of the material occurs.



   The collagen in the fleece then has to be tanned. This is done in the simplest way by spraying the fiber fleece, which has now been consolidated with collagen, with an aqueous solution containing aldehydes, preferably glutaraldehyde. The aldehyde tans the collagen.



   The collagen-poor side is then coated with a solution of polyvinylidene chloride.



   The collagen-enriched side of the sausage casing material obtained in this way can both swell and shrink, which ensures a close fit to the goods to be packaged. On the other hand, the polyvinylidene chloride adheres very well to the collagen-poor side. If it were applied to the collagen-enriched side, it would peel off. The polyvinylidene chloride is completely impermeable to water vapor and air, which is essential for many applications. In itself a packaging would also be the
Goods with a pure polyvinylidene chloride film possible, please include; If an artificial bowel is made from such a film (not according to the invention), it will, however, lie very poorly on the sausage mass, and it will form
Wrinkles and wrinkles that affect the appearance of the goods.

   If, however, the polyvinyl chloride film is combined with a collagen-bound (and enriched on one side) fleece of the type described, the intestines will always lie tightly against the sausage meat after being filled with sausage meat.
