Abstract
Description
Die Erfindung betrifft ein Verfahren zur Verhinderung von Pilz- und/oder Keimbefall bei der Verwendung von Naturfaser-Material oder einer Mischung von Naturfaser- und Kunstfasermaterial, insbesondere zur Herstellung von Dämmstoffen beim Automobilbau.The invention relates to a method for preventing fungal and / or germ infestation in the Use of natural fiber material or a mixture of natural fiber and Synthetic fiber material, in particular for the production of insulation materials in the automotive industry.
Es ist bekannt, daß insbesondere zur Auskleidung von Fahrzeugkabinen immer mehr Naturfaserprodukte verwendet werden. Es werden auch Mischungen von Naturfasern und Kunstfasern verwendet.It is known that especially for the lining of vehicle cabins more and more Natural fiber products are used. There are also blends of natural fibers and Synthetic fibers used.
Der Nachteil gegenüber der Kunststoffauskleidung liegt darin begründet, daß die Naturfasern Feuchtigkeit aufnehmen, und dadurch Pilz- und/oder Keimbefall möglich ist. Hinzu kommt noch eine zusätzliche Geruchsbelästigung, die aufgrund dieser Tatsache die zwangsläufige Folge ist.The disadvantage compared to the plastic lining is that the Natural fibers absorb moisture, and fungal and / or germ infestation is possible. In addition, there is an additional odor nuisance, which due to this fact inevitable consequence is.
Aus der DE 195 43 165 A1 ist es bereits bekannt geworden, Innenverkleidungsteile für Kraftfahrzeuge, z. B. Tür- oder Dachverkleidungen aus Naturfaser-Material herzustellen und diese mit einer Natrium und Wasser enthaltenden Flüssigkeit zu behandeln.From DE 195 43 165 A1 it has already become known for interior trim parts Motor vehicles, e.g. B. manufacture door or roof panels from natural fiber material and treat them with a liquid containing sodium and water.
Es hat sich gezeigt, daß durch die vorgeschlagene Behandlung mit der Tränkflüssigkeit die Naturfasern, z. B. einer Innenverkleidung, zwar einerseits vor Pilzbefall bzw. Keimbefall und damit gegen Verrottung gesichert werden können, daß aber andererseits durch die Behandlung zusätzliche Feuchte in das Material eindringt. Zur Erzielung gewünschter Standfestigkeiten kann in diesen Fällen eine zusätzliche Trocknung erforderlich werden, die sich sowohl vom apparativen Aufwand als auch vom Energiebedarf her als nachteilig erweist.It has been shown that the treatment proposed with the impregnating liquid Natural fibers, e.g. B. an inner panel, on the one hand, before fungal or germ infestation and thus can be secured against rotting, but on the other hand by the Treatment additional moisture penetrates into the material. To achieve the desired Stability may require additional drying in these cases is disadvantageous both in terms of equipment and energy requirements turns out.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art derart weiterzuentwickeln, daß mit geringem apparativem Aufwand und mit geringem Energiebedarf weitgehend sichergestellt ist, daß bei den eingesetzten Naturfaser- Materialien ein Pilz- und/oder Keimbefall verhindert wird. The invention has for its object a method of the type mentioned to develop that with little equipment and with little Energy requirement is largely ensured that the natural fiber used Materials a fungus and / or germ infestation is prevented.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei der Herstellung der Naturfaser-Rohlinge die einzelnen Lagen mit trockener, alkalischer Grundsubstanz gleichmäßig bestäubt werden.This object is achieved in that in the manufacture of Natural fiber blanks the individual layers with dry, alkaline basic substance be evenly pollinated.
Zweckmäßigerweise erfolgt dabei die Behandlung mit den staubförmigen, alkalischen Substanzen im Zuge der maschinellen Behandlung zur Herstellung der Faservliese bzw. Mattenrohlinge während des Herstellungsprozesses.The treatment with the dust-like, alkaline is expediently carried out Substances in the course of mechanical treatment for the production of the nonwovens or Mat blanks during the manufacturing process.
Außer der trocknen, alkalischen Grundsubstanz ist es erfindungsgemäß natürlich möglich, daß bei der Herstellung der Naturfaser-Materialien oder der Mischungen von Naturfaser- und Kunstfaser-Materialien weitere Naturextrakte und/oder Aktivkohle zudosiert werden.In addition to the dry, alkaline basic substance, it is of course possible according to the invention that in the manufacture of natural fiber materials or mixtures of natural fiber and synthetic fiber materials, further natural extracts and / or activated carbon are added.
Dieses wird vorzugsweise durch einstellbare Dosiereinrichtungen, wie Magnetrüttler und/oder Bandwaagendosierungen auf die Vliesmatteneinzelschichten aufgebracht, und durch sinnvolle Absauganordnung wird der notwendige Arbeitsschutz gewährleistet.This is preferably done by adjustable metering devices, such as magnetic vibrators and / or Belt weigher metering applied to the individual layers of fleece mat, and by sensible suction arrangement, the necessary occupational safety is guaranteed.
Ein weiterer erfindungsgemäßer Gedanke ist dadurch gegeben, daß die alkalische Grundsubstanz nicht bei der Mattenherstellung, sondern erst bei der Urformung der Kunstfaser dem Kunststoffgrundmaterial hinzugegeben wird. In der Mischung von Naturfaser und Kunstfaser entfaltet die alkalische Grundsubstanz ihre pilz- und/oder keimverhindernde Wirkung.Another idea according to the invention is given in that the alkaline Basic substance not in mat production, but only in the original shaping of the Synthetic fiber is added to the plastic base material. In the mix of Natural fiber and synthetic fiber, the alkaline substance develops its fungus and / or germicidal effect.
Bei dem vorgeschlagenen Verfahren werden Sprüh- oder Tränkeeinrichtungen, die wegen der erforderlichen Trocknung den Prozeß sehr aufwendig und energieintensiv machen, nicht benötigt. Vielmehr ist durch die Erfindung die Gewähr gegeben, daß durch die trockene Einpuderung in Form einer Dosierung die einzelnen Schichten, vorzugsweise vor der Nadelung zur Nadelfilzherstellung, so eindosiert sind, daß durch die gleichmäßige Verteilung die Gewähr gegeben ist, daß bei Feuchtigkeitsaufnahme die Aktivierung der alkalischen Stoffe zwangsläufig erfolgt und somit eine Verhinderung von Pilz- und Keimbefall geschaffen wird.In the proposed method, spray or watering devices are used because of the required drying make the process very complex and energy-intensive, not required. Rather, the invention provides a guarantee that dry powdering in the form of a dosage the individual layers, preferably before the needles for needle felt production, are metered in so that the uniform Distribution the guarantee is given that the activation of the alkaline substances inevitably occur and thus a prevention of fungal and Germ infestation is created.
Die Erfindung erweist sich besonders wirkungsvoll in den feuchten Monaten des Jahres und auch in den Wintermonaten. Wenn Wasser und/oder Schnee in das Fahrzeug mit eingebracht werden, entsteht durch Verdunsten eine hohe relative Feuchte, die dann zu einer Feuchtebenetzung dieser Dämmstoffe führt. Dieses insbesondere an den Schnitt- und Stanzstellen, an denen die einzelnen Armaturen, wie Türklinken, diverse Hebel usw., als Einbauteile den Durchbruch durch die Dämmschicht notwendig machen, und somit ein freier Zugang zu der hohen relativen Feuchte aus dem Innenraum in die Naturfaserauskleidung die zwangsläufige Folge ist.The invention proves to be particularly effective in the wet months of the year and even in the winter months. If water and / or snow get into the vehicle evaporation results in a high relative humidity, which then increases moisture dampening of these insulating materials. This especially in the cut and Punching points at which the individual fittings, such as door handles, various levers, etc., as Installation parts make the breakthrough through the insulation layer necessary, and thus a free access to the high relative humidity from the interior to the Natural fiber lining is the inevitable consequence.
Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen und ausgeführten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, daß bei der Herstellung der Naturfaserteile, vorzugsweise im Bereich vor der Konfektionierung durch Nadelung und/oder Pressung den einzelnen Schichten trockene Alkalisubstanzen z. B. Natriumcarbonat und Naturextrakte zusätzlich zur Geruchsverhinderung zugegeben werden.Of course, the invention is not limited to that described above in detail and the types of training carried out, but there are numerous Modifications possible, but without deviating from the basic idea that at Manufacture of natural fiber parts, preferably in the area before assembly Needling and / or pressing the individual layers of dry alkali substances such. B. Sodium carbonate and natural extracts added to prevent odors will.
