Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen eines Vlieses aus mit absorbierenden Mitteln versetztem Fasermaterial.The invention relates to a method for producing a web of absorbent material added to the fiber material.

Bei den sogenannten Saugvliesen werden stark saugende Fasern eingebracht, wobei entweder künstliche Fasern wie Viskose- oder Polyesterfasern oder Naturfasern wie Baumwolle, Jute und dergleichen mit stark absorbierendem Puder oder ähnlichen granulatartigen Füllstoffen versehen werden. Diese bekannten Saugvliese haben den Nachteil, dass die Saugbestandteile relativ lose im Vlies liegen und sich sowohl im trockenen als auch im nassen Zustand aus den Fasern lösen können. Es wurde daher bereits vorgeschlagen, derartige Saugvliese mit Schmelzfasern zu versehen, die dann thermisch in einem Ofen oder mit Heißluft verfestigt werden. Dies hat den Nachteil, dass es zu einer starken Einschränkung der Expansionsmöglichkeiten der Vliesstoffe kommt, da die Fasern miteinander verklebt werden und das mögliche Aufnahmevolumen durch diese fixierten Fasern beschränkt ist.In the so-called Saugvliesen strongly absorbent fibers are introduced, either artificial fibers such as viscose or polyester fibers or natural fibers such as cotton, jute and the like are provided with highly absorbent powder or similar granular fillers. These known suction nonwovens have the disadvantage that the absorbent components are relatively loose in the fleece and can be released from the fibers both in the dry state and in the wet state. It has therefore already been proposed to provide such absorbent nonwovens with melt fibers, which are then thermally solidified in an oven or with hot air. This has the disadvantage that there is a strong limitation of the expansion possibilities of the nonwovens, since the fibers are glued together and the possible receiving volume is limited by these fixed fibers.

Der Erfindung liegt die Aufgabe zu Grunde ein Vlies der eingangs genannten Art zu schaffen, welches, wenn überhaupt, nur geringfügige Beschränkung der Expansionsfähigkeit aufweist und ein entsprechend hohes Aufnahmevermögen für Flüssigkeit besitzt.The invention has for its object to provide a nonwoven of the type mentioned, which, if at all, has only a slight restriction of the expansion capability and has a correspondingly high absorption capacity for liquid.

Erfindungsgemäß wird bei dem Verfahren zur Herstellung eines Flüssigkeit absorbierenden Vlieses aus Fasermaterial mit absorbierendem Mittel und gekräuselten Bindungsfasern sowie Vernadeln des Fasermaterials mit den Bindungsfasern diese Aufgabe dadurch gelöst, dass als absorbierendes Mittel saugendes Material, nämlich Polykarbonatgranulat bzw. -pulver, in das Fasermaterial, nämlich Viskose- oder Polyesterfaser, eingebracht wird. Dabei ermöglichen die Bindungsfasern einerseits auf Grund der gekräuselten Struktur und andererseits der rein mechanischen Bindung durch das Vernadeln eine weitest gehende Freiheit für das Fasermaterial sich bei der Aufnahme von Flüssigkeit auszudehnen, die Dicke und Vliesfestigkeit kann durch dieses Verfahren relativ frei bestimmt werden.According to the invention, in the process for producing a liquid-absorbent nonwoven fabric comprising absorbent material and crimped bonding fibers and needling the fiber material with the bonding fibers, this object is achieved by absorbing absorbent material, namely polycarbonate granules or powder, into the fiber material, namely Viscose or polyester fiber is introduced. On the one hand, because of the crimped structure and, on the other hand, the purely mechanical binding by needling, the binding fibers allow the widest possible freedom for the fiber material to expand when taking up liquid, the thickness and nonwoven strength can be determined relatively freely by this method.

Vorteilhafter Weise wird ein Anteil an Bindungsfasern von 1 bis 35%, vorzugsweise 5 bis 20%, bezogen auf das Fasermaterial zugemischt werden. Damit kann je nach Grad der Zumischung der Bindungsfasern einerseits die mechanische Festigkeit des Vlieses gesteuert werden und andererseits auch die für die Festigkeit optimale Ausdehnungsmöglichkeit zu geben. Schichtdicken von etwa 2 Millimeter bis 25 Millimeter können sich je nach Fasermaterialanteil bis zu 80 Millimeter ausdehnen und bis zum 100-fachen des Eigengewichts an Flüssigkeit aufnehmen. Die Zugabe der Bindungsfasern in Abhängigkeit vom Prozentanteil am Gesamtvlies steuert die mechanische Festigkeit des Vlieses, wobei der Anteil an saugendem Puder oder ähnlichen granulatartigen Füllstoffen in den Fasern des Fasermaterials eingebaut sein kann, womit die Haftung des saugenden Materials im Vlies wesentlich verbessert ist. Dieses saugende Material ist ein Polykarbonatgranulat bzw. -pulver und kann bei der Erzeugung des Fasermaterials, nämlich Viskose- oder Polyesterfaser, bei deren Erzeugung bereits eingebracht werden.Advantageously, a proportion of binding fibers of 1 to 35%, preferably 5 to 20%, based on the fiber material will be added. Thus, depending on the degree of admixture of the binding fibers, on the one hand, the mechanical strength of the fleece can be controlled and, on the other hand, it can also give the optimum expansion capability for the strength. Layer thicknesses of about 2 millimeters to 25 millimeters can expand up to 80 millimeters, depending on the proportion of fiber material, and absorb up to 100 times the weight of liquid. The addition of the binding fibers as a function of the percentage of the total web controls the mechanical strength of the web, wherein the content of absorbent powder or similar granular fillers can be incorporated in the fibers of the fiber material, whereby the adhesion of the absorbent material in the web is substantially improved. This absorbent material is a polycarbonate granulate or powder and can already be introduced during the production of the fiber material, namely viscose or polyester fiber, during their production.

Vorteilhafter Weise weisen die zugemischten Bindungsfasern eine Länge von 6 bis 15 Zentimeter auf. Mit dieser Länge kann die Dehnungsmöglichkeit des Vlieses entsprechend gesteuert werden, wobei die mechanische Verfestigung des Vlieses die bestimmende Determinante für die im trockenen Zustand bestimmte dreidimensionale Form des Vlieses ist. Je nach Einsatzzweck können leicht verformbare Vliese oder relativ starke Matten produziert werden, die je nach Anwendung auch im vollgesaugtem Zustand noch Festigkeit aufweisen und dabei Blockaden für nachfolgende Flüssigkeitsmengen darstellen oder weiche gelartige Zustände haben und ein Maximum an Aufnahmevolumen bereitstellen. Das Fasermaterial besteht dabei aus Fasern, die eine Länge von 40 bis 200 Millimeter haben und sowohl glatt als auch gekräuselt sein können. Der Grad der Verfestigung wird dabei durch den Vernadelungsgrad ebenso gesteuert wie durch den Anteil an Bindungsfasern.Advantageously, the admixed binding fibers have a length of 6 to 15 centimeters. With this length, the possibility of stretching the fleece can be controlled accordingly, wherein the mechanical hardening of the fleece is the determining determinant of the three-dimensional shape of the fleece determined in the dry state. Depending on the intended use, easily deformable nonwovens or relatively strong mats can be produced, which, depending on the application, still have firmness even in the fully soaked state and represent blockages for subsequent liquid quantities or have soft gelatinous states and provide a maximum of absorption volume. The fiber material consists of fibers that have a length of 40 to 200 millimeters and can be both smooth and curled. The degree of solidification is controlled by the degree of needling as well as by the proportion of binding fibers.

Vorteilhafter Weise kann das Fasermaterial und/oder die zugemischten Bindungsfasern mit antibakteriellen Mitteln und/oder Duftstoffen und/oder Duftneutralisierern beladen werden. Dies ist insbesondere dann angezeigt, wenn das hergestellte Vlies zum Auffangen von Flüssigkeiten eingesetzt wird, die nur langsam in das Vlies eintreten bzw. nur periodisch auftreten, wobei dann in der Zeit, in der das Vlies in feuchtem Zustand vorliegt, z. B. Schimmelpilzbefall durch Zugabe von pilztötenden Materialien verhindert werden kann. Dies ist auch unter dem Aspekt zu sehen, dass das Vlies sich innerhalb großer Grenzen wieder auf das ursprüngliche Maß zurückbilden kann, das heißt, dass bei Trocknung eines mit Wasser oder Flüssigkeit beladenen Vlieses dieses zu einem hohen Grade wieder die ursprüngliche Struktur und Ausdehnung erlangen kann.Advantageously, the fiber material and / or the admixed binding fibers can be loaded with antibacterial agents and / or fragrances and / or fragrance neutralizers. This is particularly indicated when the fabric produced is used to collect liquids that occur only slowly in the web or occur only periodically, in which case in the time in which the fleece is in a moist state, for. B. Mold infestation by addition of fungicidal materials can be prevented. This is also to be seen from the aspect that the fleece can re-form within large limits to the original level, that is, when drying a fleece loaded with water or liquid, this can recover to a high degree the original structure and expansion again ,

Schließlich kann das Vlies auf formbeständige Träger aufgebracht werden, was sich insbesondere dann als angezeigt erachtet, wenn der formbeständige Träger als Auffangbehälter ausgebildet ist, in welchen z. B. eine Autobatterie oder ein sonstiger, mit Flüssigkeit befüllter Behälter aufzubewahren ist, wobei verhindert werden muss, dass diese Flüssigkeit ungehindert austritt. Damit werden in der Elektrotechnik Kurzschlüsse bei Austreten von Flüssigkeiten aus Batterien verhindert, weiters auch die Schädigung von Fahrzeugteilen oder sonstigen tragenden Teilen durch austretende Batteriesäure, ebenso können Verletzungen mit heißem Wasser, Kühlflüssigkeiten oder sonstigen Sachen verhindert werden, was insbesondere im Zuge des Trends zum Elektroauto sehr wesentlich ist.Finally, the fleece can be applied to dimensionally stable support, which is particularly appropriate when the dimensionally stable support is designed as a collecting container in which z. B. is a car battery or other, liquid-filled container is to be stored, it must be prevented that this liquid exits unhindered. This prevents short circuits in the leakage of liquids from batteries in electrical engineering, furthermore also the damage to vehicle parts or other load-bearing parts due to escaping battery acid, as well as injuries with hot water, coolants or other things can be prevented, especially in the wake of the trend to electric car is very essential.
