Definitions
- the present invention relates to a shoe inner material with adsorbing properties, in which as the adsorbent material, e.g. activated carbon is used to adsorb sweat and odorous substances.
- adsorbent material e.g. activated carbon
- activated carbon has good adsorption properties, and is therefore also particularly suitable for adsorbing body vapors such as sweat and the odorous substances contained therein. For this reason, attempts have been made in some way to incorporate activated carbon as an adsorbent material into the inner material of shoes. For example, it has been proposed to incorporate the activated carbon into a latex foam and to produce insoles for shoes from the latex foam thus obtained. However, it turned out to be disadvantageous that the activated carbon was no longer freely accessible to the substances to be adsorbed due to the embedding in the latex foam, as a result of which the adsorbing effect was largely lost.
- the object of the present invention is therefore to create a shoe inner material with adsorbing properties of the type mentioned in the introduction, in which the adsorbing activated carbon is freely accessible on the one hand for substances to be adsorbed, but on the other hand nevertheless has a high abrasion resistance.
- a shoe inner material in which activated carbon particles are fixed in a punctiform manner on the side facing away from the foot by means of an adhesive.
- the shoe inner material according to the invention can e.g. between the upper leather and the lining of the shoe, between the main sole and insole or as an intermediate layer in an insole or in a footbed.
- the shoe inner material can also be designed as a covering material for the footbed of the shoe.
- very hard activated carbon particles are preferably used as the adsorbent for the shoe inner material according to the invention. These activated carbon particles are preferably spherical or largely spherical.
- the diameter of the activated carbon particles is preferably between 0.1 mm and 1 mm.
- the shoe inner material according to the invention is particularly well suited for combat boots with integrated C protection or safety boots with protection against aggressive chemicals. Sedentary warfare agents pose a great danger to the soldier's feet. Today's NBC protection provides special overboots to protect against such warfare agents. However, it can happen that these overboots are damaged or not at hand at the crucial moment.
- the shoe inner material according to the invention provides a remedy here, because it adsorbs the warfare agents.
- Combat boots equipped with the shoe inner material according to the invention therefore ensure considerably higher security for the soldier.

Abstract
Description
- Die vorliegende Erfindung betrifft ein Schuhinnenmaterial mit adsorbierenden Eigenschaften, bei dem als Adsorbensmaterial, z.B. zur Adsorption von Schweiß und Geruchsstoffen, Aktivkohle verwendet wird.
- Aus dem Stand der Technik ist bekannt, daß Aktivkohle gute Adsorptionseigenschaften aufweist, insbesondere also auch zur Adsorption von Körperausdünstungen wie Schweiß und den darin enthaltenen Geruchsstoffen geeignet ist. Aus diesem Grund hat man bereits versucht, Aktivkohle als Adsorbensmaterial in irgendeiner Weise in das Innenmaterial von Schuhen einzuarbeiten. Beispielsweise wurde vorgeschlagen, die Aktivkohle in einen Latexschaum einzuarbeiten und aus dem so erhaltenen Latexschaum Einlegesohlen für Schuhe herzustellen. Dabei erwies sich jedoch als nachteilig, daß die Aktivkohle durch die Einbettung in den Latexschaum für die zu adsorbierenden Stoffe nicht mehr frei zugänglich war, wodurch die adsorbierende Wirkung zu einem großen Teil verloren ging. Man hat daher versucht, die freie Zugänglichkeit der Aktivkohle in dem Schuhinnenmaterial dadurch zu erhöhen, daß die Aktivkohle weniger stark in das Material eingebunden wurde. Dies hat jedoch dazu geführt, daß die Aktivkohle nicht mehr vollständig vom Binder festgehalten wurde, so daß aufgrund des Abriebs das Schuhinnenmaterial schwarz ausfärbte.
- Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, ein Schuhinnenmaterial mit adsorbierenden Eigenschaften der eingangs genannten Art zu schaffen, bei dem die adsorbierende Aktivkohle einerseits für zu adsorbierende Stoffe frei zugänglich ist, das andererseits aber dennoch eine hohe Abriebfestigkeit besitzt.
- Die Lösung dieser Aufgabe liefert ein Schuhinnenmaterial, bei dem Aktivkohleteilchen auf der dem Fuß abgewandten Seite mittels einer Haftmasse punktförmig fixiert sind. Das erfindungsgemäße Schuhinnenmaterial kann z.B. zwischen Oberleder und Innenfutter des Schuhs, zwischen Hauptsohle und Brandsohle oder auch als Zwischenschicht in einer Einlegesohle bzw. in einem Fußbett angeordnet werden. Das Schuhinnenmaterial kann auch als Abdeckmaterial für das Fußbett des Schuhs ausgebildet sein. Zur Gewährleistung der geforderten Abriebfestigkeit werden vorzugsweise sehr harte Aktivkohleteilchen als Adsorbens für das erfindungsgemäße Schuhinnenmaterial verwendet. Diese Aktivkohleteilchen sind vorzugsweise kugelförmig bzw. weitgehend kugelförmig. Vorzugsweise liegt der Durchmesser der Aktivkohleteilchen zwischen 0,1 mm und 1 mm.
- Für die Zwecke der Erfindung geeignete Materialien sind beispielsweise aus der DE-C-29 51 827, der EP-B-90 073 und der EP-B-118 618 bekannt, deren Inhalt Teil der Offenbarung der vorliegenden Erfindung sein soll.
Durch die punktförmige Fixierung der Aktivkohleteilchen nach der EP-B-118 618 ist gewährleistet, daß etwa 85 % der Oberfläche der Aktivkohle frei zugänglich ist, so daß die vorhandene Adsorptionskapazität weitestgehend erhalten bleibt. Der Auftrag der Haftmasse erfolgt nicht als geschlossener Flächenauftrag, sondern punktförmig, damit die Atmungsaktivität des Materials erhalten bleibt. Das Auftragen der Haftmasse kann z.B. in der in der EP-B-118 618 beschriebenen Weise durch Rotationsschablonendruck erfolgen. Hier bedarf es eines Klebers, der neben hoher mechanischer Festigkeit und Elastizität sowie einem gewissen Penetrationsvermögen auch eine ausreichende Anfangsklebrigkeit haben muß, um die aufgestreuten Aktivkohlekügelchen bis zum Erreichen der Festigkeit festzuhalten. Dieser Forderung werden von den in der EP-B-118 618 beschriebenen Haftmassen insbesondere lösungsmittelarme bzw. lösungsmittelfreie (20 bis 0 %) IMPRANIL High-Solid-PUR-Reaktivprodukte R von BAYER gerecht. Hierbei handelt es sich um NCO-Prepolymere, die zur Erhaltung einer langen Topfzeit blockiert sind und die mit jeweils einer festgelegten Menge eines Diamins (z.B. IMPRAFIX HS-C) vernetzt werden. - Das erfindungsgemäße Schuhinnenmaterial ist insbesondere gut für Kampfstiefel mit integriertem C-Schutz oder Sicherheitsstiefel mit Schutz gegen aggressive Chemikalien geeignet. Seßhafte Kampfstoffe stellen für die Füße des Soldaten eine große Gefahr dar. Zum Schutz gegen solche Kampfstoffe sieht der heutige ABC-Schutz spezielle Überziehstiefel vor. Es kann jedoch vorkommen, daß diese Überziehstiefel beschädigt oder im entscheidenden Augenblick nicht zur Hand sind. Das erfindungsgemäße Schuhinnenmaterial schafft hier Abhilfe, da es die Kampfstoffe adsorbiert. Mit dem erfindungsgemäßen Schuhinnenmaterial ausgerüstete Kampfstiefel gewährleisten daher eine beträchtlich höhere Sicherheit für den Soldaten.
