Description

Verfahren zur Herstellung eines wd@eerdichten Belages auf Faserstoffbauschen Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines wasserdichten Belages auf Faserstoffbauschen und kennzeichnet sich dadurch, daß man dem natürlichen Gummi' ähnliche, synthetisch hergestellte, gelöste Polymerisate insbesondere der Akrylsäure, des Vinylalkohols oder eines Vinylesters auf eine Unterl,.ge gießt und vor der Verflüchtigung des Lösungsmittels den Faserstoffbausch auflegt. Als Faserstoffbausch kommt insbesondere Watte in Betracht. Ein Aufspritzen oder Auftragen der ungelösten Polymerisate kommt zur Herstellung des gewünschten Produktes nicht in Frage, da in diesem Fall das Material zu weit in das Innere des Bausches eintreten würde, um so einerseits diesen in der Absorptionsfähigkeit zu beeinträchtigen, andererseits die Bildung eines durchgehend wasserdichten Belages zu.verhindern.Process for the production of a waterproof covering on fibrous tissue The present invention relates to a method for making a waterproof one Covering on fiber bulges and is characterized by the fact that one is the natural Synthetic, synthetic, dissolved polymers similar to rubber ', in particular the Acrylic acid, vinyl alcohol or a vinyl ester on a base .ge pours and before the solvent evaporates, the fiber wad is applied. As a fiber bulk In particular, cotton wool comes into consideration. A splash or application of the undissolved Polymers are out of the question for the production of the desired product, since in this case the material would penetrate too far into the inside of the bulge, in order to impair the absorption capacity on the one hand, on the other hand to prevent the formation of a continuously watertight coating.

In der Zeichnung-ist ein erfindungsgemäßer Bausch dargestellt.In the drawing, a pad according to the invention is shown.

Eine Wattelage i ist auf der einen Seite mit -einem Belag 2 aus Polymerisaten versehen.A wadding layer i has a covering 2 made of polymers on one side Mistake.

Zur Herstellung löst man die in Betracht kommenden Polymerisate z. B. der Akrylsäure in geeigneten Lösungsmitteln, z. B. Essigester, Aceton, Methylenchlorid. Die Lösung wird auf eine ebene -Unterlage, z. B. eine Glasplatte, gegossen, und auf die noch feuchte Schicht wird die Wattebahn oder eine sonstige Faserstoffbahn aufgelegt. Nach vollkommenem Verdampfendes Lösungsmittels haftet auf der einen Seite des Wattebausches o. dgl. ein wasserundurchlässiger Belag, der in derselben Weise auch auf der anderen Seite hergestellt werden kann.To prepare, dissolve the polymers in question, for. B. acrylic acid in suitable solvents, e.g. B. ethyl acetate, acetone, methylene chloride. The solution is placed on a flat surface, e.g. B. a glass plate, cast, and The wad of cotton wool or another fibrous web is placed on the still moist layer hung up. After the solvent has completely evaporated, it adheres to one side the cotton ball o. The like. A waterproof covering, which in the same way can also be made on the other side.

Je nach Konsistenz des Polymerisates kann dafür gesorgt werden, daß der Belag zwar wasserdicht, jedoch für Luft durchlässig ist. Dies ist nicht nur für feuchte Verbände außerordentlich vorteilhaft, sondern macht auch den Polymerisatbelag vorteilhaft für gewebte Faserstoffe, wie insbesondere Trikot, oder überhaupt solche Stoffe, die eine gewisse Behaarung auf ihrer Oberfläche aufweisen.Depending on the consistency of the polymer, it can be ensured that the surface is waterproof, but air permeable. This is not just extremely beneficial for damp dressings, it also makes the polymer coating advantageous for woven fibers, such as tricot in particular, or such at all Substances that have a certain amount of hair on their surface.

Der erfindungsgemäße Fasersfoffbausch ist vielfach verwendbar. Bei feuchten Verbänden, bei denen man sich bisher einer gesonderten wasserdichten Unterlage, z. B. Guttapercha oder Gummistoff, bediente, ist diese Unterlage' nicht mehr erforderlich. Auch für blutstillende Verbände, also auch für Damenbinden läßt sich der erfindungsgemäße Faserstoffbausch verwenden. Er kommt im übrigen auch für Polstermaterial in Betracht, beispielsweise für Bekleidungsstücke.The fiber wad according to the invention can be used in many ways. at damp dressings, where you previously had to use a separate waterproof pad, z. B. gutta-percha or rubber, this document is no longer required. The invention can also be used for hemostatic bandages, that is to say also for sanitary napkins Use pulp. It can also be used for upholstery material, for example for clothing.
