- the shoe insole is an important part of a shoe.
- the outsole and the shoe upper are attached to the insole. It rarely consists of leather, usually a binder-strengthened cellulose or nonwoven material, to which the outsole is attached by sewing, stapling or gluing. Above all, the process of molding on or foaming the outsole made of plastics is used. Especially for leisure and sports shoes, very light shoe insoles are required, which have to be foam and splash-proof.
- insole materials would have to have two and a half to three times the density, equivalent to up to three times the basis weight, in order to ensure that they are splash-proof and foam-tight.
- the publication DE 3231971 describes the production of an insole made of nonwoven, into which thermoplastic hollow microspheres are introduced.

Abstract
Description
Die Erfindung betrifft eine Schuhinnensohle aus binderhaltigem Vliesstoff mit eingelagerten kompakten Mikrokugeln.The invention relates to a shoe insole made from binder-containing nonwoven fabric with embedded compact microspheres.
Die Schuhinnensohle stellt einen wichtigen Teil eines Schuhes dar. An der Innensohle wird die Laufsohle und der Schuhoberteil befestigt. Sie besteht selten noch aus Leder, üblicherweise aus einem binderverfestigten Zellulose- oder Vliesstoffmaterial, an welche die Laufsohle durch Vernähen, Klammern oder Verkleben angebracht wird. Vor allem wird das Verfahren des Anspritzens oder Anschäumens der Laufsohle aus Kunststoffen eingesetzt. Besonders bei Freizeit- und Sportschuhen werden sehr leichte Schuhinnensohlen gefordert, welche anschäum- und anspritzdicht sein müssen.The shoe insole is an important part of a shoe. The outsole and the shoe upper are attached to the insole. It rarely consists of leather, usually a binder-strengthened cellulose or nonwoven material, to which the outsole is attached by sewing, stapling or gluing. Above all, the process of molding on or foaming the outsole made of plastics is used. Especially for leisure and sports shoes, very light shoe insoles are required, which have to be foam and splash-proof.
Nachteile bei den herkömmlichen Schuhinnensohlen ergeben sich bei letztgenanntem Verfahren. Der zu schäumende oder spritzende flüssige Kunststoff dringt besonders bei leichten Innensohlenmaterialien durch diese hindurch, verursacht auf der gegenüberliegenden Seite Wülste und Unregelmäßigkeiten, die jeden Tragekomfort zunichte machen.Disadvantages with conventional shoe insoles arise with the latter method. The liquid plastic to be foamed or sprayed penetrates through it, particularly in the case of light insole materials, causing bulges and irregularities on the opposite side, which negate any wearing comfort.
Diese Innensohlenmaterialien müßten die zweieinhalb- bis dreifache Dichte aufweisen, gleichbedeutend mit dem bis zu dreifachem Flächengewicht, um eine Anspritz-, Anschäumdichtheit zu gewährleisten.These insole materials would have to have two and a half to three times the density, equivalent to up to three times the basis weight, in order to ensure that they are splash-proof and foam-tight.
In der Offenlegungsschrift DE 3231971 wird die Herstellung einer Brandsohle aus Vliesstoff beschrieben, in welche thermoplastische Mikrohohlkugeln eingebracht sind.The publication DE 3231971 describes the production of an insole made of nonwoven, into which thermoplastic hollow microspheres are introduced.
Das Problem des Durchdringens der anzuspritzenden, anzuschäumenden Laufsohle durch herkömmliche Schuhinnensohlen wurde in DE-OS 32 31 971 nicht erkannt. Es wird lediglich auf eine angebliche bessere Wärmedämmung und Fußabstützung durch die erfindungsgemäße Brandsohle verwiesen.The problem of penetration of the outsole to be molded on, to be foamed through conventional shoe insoles was not recognized in DE-OS 32 31 971. It is only referred to an alleged better thermal insulation and foot support by the insole according to the invention.
Nachteil des Herstellungsverfahrens der thermoplastischen Mikrohohlkugeln ist der sehr hohe Preis. Die Fertigung ist nur auf modernsten Maschinen mit sehr genauer Temperaturführung möglich, da bei Untertemperatur die Mikrohohlkugeln sich nicht bilden und bei Übertemperatur zerplatzen.The disadvantage of the manufacturing process of the hollow thermoplastic microspheres is the very high price. Manufacturing is only possible on the most modern machines with very precise temperature control, since the hollow microspheres do not form at low temperatures and burst at high temperatures.
Aufgabe der Erfindung ist es, eine Schuhinnensohle herzustellen, die sehr leicht, hochflexibel, dehnarm, vor allen anspritz-, anschäumdicht ist und die Nachteile des Standes der Technik nicht aufweist.The object of the invention is to produce a shoe insole that is very light, highly flexible, low-stretch, above all splash-proof, foam-proof and does not have the disadvantages of the prior art.
Diese Aufgabe wird erfindungsgemäß durch eine Schuhinnensohle aus binderhaltigem Vliesstoff mit eingelagerten Mikrokugeln gelöst, deren Mikrokugeln kompakt sind und die in einer solchen Menge in den binderhaltigen Vliesstoff eingelagert sind, daß die Schuhinnensohle gegen aufgeschäumten oder aufgespritzten Kunststoff undurchlässig wird.This object is achieved according to the invention by a shoe insole made of binder-containing nonwoven fabric with embedded microspheres, the microspheres of which are compact and which are embedded in the binder-containing nonwoven fabric in such an amount that the shoe insole becomes impermeable to foamed or sprayed-on plastic.
Gemäß einer Ausführungsform werden kompakte Mikrokugeln mit einem Durchmesser von 0,040 mm bis 0,500 mm verwendet. Gemäß einer besonders bevorzugten Ausführungsform können jedoch wesentlich kompaktere Mikrokugeln mit einem um drei Zehnerpotenzen kleineren Durchmesser, nämlich im Bereich von 5 bis 15 Nanometern eingesetzt werden.According to one embodiment, compact microspheres with a diameter of 0.040 mm to 0.500 mm are used. According to a particularly preferred embodiment, however, much more compact microspheres with a diameter smaller by three powers of ten, namely in the range from 5 to 15 nanometers, can be used.
Die Menge der verwendeten Mikrohohlkugeln wird so gewählt, daß eine vollständige Dichtigkeit der Innensohle beim Anspritzen oder Anschäumen mit Kunststoffen zwecks Befestigung der Laufsohle an der Schuhinnensohle erzielt wird. Hierfür reichen in Abhängigkeit vom Kugelmaterial Mengen von 2 bis 20 Gew.-%, bezogen auf binderhaltigen Vliesstoff, in der Regel aus.The amount of hollow microspheres used is chosen so that the insole is completely sealed when molded or foamed with plastics for fastening the outsole is achieved on the insole of the shoe. Depending on the ball material, amounts of 2 to 20% by weight, based on the nonwoven containing binder, are generally sufficient for this.
Der an sich bekannte Vliesstoff kann aus synthetischen natürlichen und regenerierten Fasern bestehen, wobei Polyesterfasern bevorzugt sind.The nonwoven fabric known per se can consist of synthetic natural and regenerated fibers, with polyester fibers being preferred.
Der Faseranteil des bindehaltigen Vliesstoffes liegt vorteilhaft im Bereich von 30 bis 60 Gew.-%. Als Grundlage für das Faservlies dient vorteilhaft ein Gewebe. Der Vliesstoff wird in der Regel mit dieser Unterlage mechanisch durch Vernadeln verbunden. Vorteilhaft dient ein Polypropylenbändchengewebe als Vliesstoffunterlage.
Das Gewebe bewirkt eine geringe Dehnung, welche sich günstig auf die Formstabilität und Verarbeitung der Innensohle auswirkt.The fiber content of the nonwoven containing binders is advantageously in the range from 30 to 60% by weight. A fabric advantageously serves as the basis for the nonwoven. The nonwoven is usually mechanically connected to this base by needling. A polypropylene tape fabric advantageously serves as a nonwoven underlay.
The fabric causes little stretching, which has a positive effect on the shape stability and processing of the insole.
Die Mikrokugeln bestehen vorzugsweise aus anorganischem Material, das synthetischen oder natürlichen Ursprungs sein kann. Bevorzugte Beispiele sind Mikroglaskugeln, die einen Durchmesser von 0,04 - 0,08 mm aufweisen. Für die Mikrokugeln von Durchmessern im Nanometerbereich hat sich als besonders vorteilhaft Siliciumdioxid mit einer Dichte von 1,0 bis 1,2 g/cm³ erwiesen. Ebenso geeignet sind Metalloxide oder deren Mischungen sowie wasserunlösliche organische oder anorganische Salze.The microspheres preferably consist of inorganic material, which can be of synthetic or natural origin. Preferred examples are micro glass balls which have a diameter of 0.04-0.08 mm. Silicon dioxide with a density of 1.0 to 1.2 g / cm³ has proven to be particularly advantageous for the microspheres with diameters in the nanometer range. Metal oxides or their mixtures and water-insoluble organic or inorganic salts are also suitable.
Mittels des Binders, der beispielsweise aus Latices auf Basis von Acrylsäureestern, Acrylnitrilbutadien, Styrolbutadien oder aus deren Abmischungen besteht, werden die kompakten Mikrokugeln in die Zwischenräume des Vliesstoffes eingebracht. Der Binder lagert sich normalerweise an den Faserkreuzungspunkten und nicht in den von Fasern umgebenen Hohlräumen des Vliesstoffes an.The compact microspheres are introduced into the interstices of the nonwoven fabric by means of the binder, which consists, for example, of latices based on acrylic acid esters, acrylonitrile butadiene, styrene butadiene or their mixtures. The binder is usually attached to the Fiber crossing points and not in the cavities of the nonwoven fabric surrounded by fibers.
Die Mikrokugeln liegen jedoch in den Hohlräumen des Vliesstoffes und bilden wie die Faserkreuzungspunkte zusätzliche Verankerungsstellen für den Binder. Zwischen den Mikroglaskugeln und den Fasern wird eine Art Segel aufgespannt, die aus Latex bestehen und die Innensohle soweit abdichten, daß die Luftdurchlässigkeit kleiner 61 l/m²/sec beträgt und die Innensohle anschäum-, anspritzdicht ist. Die durch die Segel neugebildeten, jetzt kleineren Hohlräume sorgen auch für Kälte- und Wärmedämmung, geringe Dichte und somit geringes Gewicht und hohe Flexibilität bei entsprechendem Binder. Mittels der besonders kompakten Mikrokugeln mit Durchmessern im Bereich von 5 bis 50 Nanometern können die Hohlräume im Vliesstoff vollständig ausgefüllt werden, womit auf einfachste Weise die gewünschte Luftundurchlässigkeit erreicht wird. Der Dichteeffekt wird noch gesteigert, da sich das verwendete Bindemittel mit den Mikrokugeln zu einem fast folienartigen Verbund verbindet.However, the microspheres lie in the cavities of the nonwoven and, like the fiber crossing points, form additional anchoring points for the binder. Between the micro glass balls and the fibers, a kind of sail is stretched, which consist of latex and seal the insole to such an extent that the air permeability is less than 61 l / m² / sec and the insole is foam-proof, splash-proof. The cavities newly formed by the sails, now smaller, also provide cold and heat insulation, low density and thus low weight and high flexibility with the appropriate binder. By means of the particularly compact microspheres with diameters in the range of 5 to 50 nanometers, the voids in the nonwoven fabric can be completely filled, so that the desired air impermeability is achieved in the simplest way. The density effect is increased even further, since the binder used combines with the microspheres to form an almost film-like composite.
Mikroglaskugeln sind von der Fa. Potters-Ballotini mit Sitz in Kirchheim-Bolanden unter dem Markennamen Ballotini Microglaskugeln zu beziehen.Micro glass balls are available from Potters-Ballotini, based in Kirchheim-Bolanden, under the brand name Ballotini micro glass balls.
Kugelförmiges Siliciumdioxid eines Durchmessers im Bereich von 5 bis 50 Nanometer und einer Dichte von 1,0 bis 1,2 g/cm³ ist unter dem Markennamen AEROSIL, Hersteller DEGUSSA im Handel.Spherical silicon dioxide with a diameter in the range from 5 to 50 nanometers and a density from 1.0 to 1.2 g / cm³ is commercially available under the brand name AEROSIL, manufacturer DEGUSSA.
Die Vorteile der Mikrokugeln gegenüber den in der Offenlegungsschrift DE 3231971 beschriebenen Mikrohohlkugeln sind im Preis und in der Verarbeitung zu finden. Sie sind bis zum 12,5-fachen billiger und bei der Verarbeitung temperaturun empfindlich.The advantages of the microspheres compared to the hollow microspheres described in the published patent application DE 3231971 can be found in the price and the processing. They are up to 12.5 times cheaper and have a lower temperature when processed sensitive.
Da die Schuhinnensohle im engen Kontakt mit schweißabsondernden Füßen des Menschen steht, ist es für Hygiene und Gesundheit von großem Vorteil, wenn diese mit einem bakteriziden Mittel ausgerüstet ist. Bakterizide Mittel werden über den Binder oder die Fasern in die Innensohle eingebracht.Since the insole of the shoe is in close contact with sweat-releasing feet, it is of great advantage for hygiene and health if it is equipped with a bactericidal agent. Bactericidal agents are introduced into the insole via the binder or the fibers.
Für gute klimatische Bedingungen im Innenschuh sorgen feuchtigkeitsabsorbierende Mittel in der Innensohle. Diese Bedingungen werden durch den hydrophilen Binder und das Einbringen von Zellwollfasern in den Vliesstoff erreicht.Moisture-absorbing agents in the insole ensure good climatic conditions in the liner. These conditions are achieved through the hydrophilic binder and the incorporation of cellulose fibers into the nonwoven.
Die Erfindung wird durch die nachfolgenden Beispiele und die Figur näher erläutert:The invention is illustrated by the following examples and the figure:
Die Schuhinnensohle (1) besteht aus einem Nadelvliesstoff (2), der auf ein Polypropylen-Bändchengewebe (3) aufgenadelt ist. Die Mikrokugeln werden zunächst einem wäßrigen NBR- oder SBR-Latex mittels Rühren zugegeben. Danach wird der Vliesstoff mit der Mischung aus Binder und Mikrokugeln imprägniert, getrocknet und vulkanisiert. In den Zwischenräumen des Vliesstoffes verbleiben die Mikroglaskugeln mit einem Durchmesser von 0,04 - 0,08 mm (4) und bilden zusätzliche Verankerungspunkte mit dem Binder (5). Bezugsziffer (6) zeigt einen vergrößerten Bereich des Vlieses (2).The shoe insole (1) consists of a needle fleece (2), which is needled onto a polypropylene ribbon fabric (3). The microspheres are first added to an aqueous NBR or SBR latex by stirring. The nonwoven fabric is then impregnated with the mixture of binder and microspheres, dried and vulcanized. The micro-glass balls with a diameter of 0.04 - 0.08 mm (4) remain in the spaces between the nonwovens and form additional anchoring points with the binder (5). Reference number (6) shows an enlarged area of the fleece (2).
In den Zwischenräumen des gleichen Vliesstoffes wie in Beispiel 1 beschrieben, sind Mikroglaskugeln (4) aus Silicium dioxid in einer Korngröße von 10 bis 20 Nanometern zusammen mit Bindemittel eingelagert. Das SiO₂ verbindet sich mit dem Bindemittel indem es suspendiert wird, (NBR- oder SBR-Latex) zu einem folienartigen Verbund, so daß bei 20 mm Wassersäule keine Luftdurchlässigkeit meßbar ist. Durch die niedrige Dichte des SiO₂ ergibt sich ein niedrigeres Gewicht der Schuhinnensohle.In the interstices of the same nonwoven as described in Example 1, micro glass balls (4) are made of silicon dioxide with a grain size of 10 to 20 nanometers is stored together with binder. The SiO₂ combines with the binder by being suspended (NBR or SBR latex) to form a film-like composite, so that no air permeability can be measured at a water column of 20 mm. The low density of SiO₂ results in a lower weight of the shoe insole.
