Description

Mischfαse rvl ies u n d Ve rf a h re n zu se i n e r H e rste l l u n g Mischfαse rvl ies u d d pro cedure to se a r e rste l l u n g
Die Erfindung betrifft ein Mischfaservlies, insbesondere als Füllmaterial für Bettwaren, Textilien, Polstermöbel, Automobilinterieur oder als Isolation oder Dämmung sowie ein Verfahren zu seiner Herstellung.The invention relates to a mixed fiber fleece, in particular as a filling material for bedding, textiles, upholstered furniture, automobile interiors or as insulation or insulation, and a method for its production.
Es ist ein Mischfaservlies aus Schafschurwolle und Kapok bekannt, das als Füllmaterial für Bettwaren, Bekleidung, Kinderausstattung und dergl. verwandt wird, um vor allem den hygienischen Bedürfnissen Rechnung zu tragen und gleichzeitig ein reines Naturprodukt anbieten zu können, welches auch umweltfreundlich entsorgt werden kann.A mixed fiber fleece made of sheep's wool and kapok is known, which is used as a filling material for bedding, clothing, children's equipment and the like, in order to take into account above all the hygienic requirements and at the same time to be able to offer a pure natural product that can also be disposed of in an environmentally friendly manner.
Nachteilig an diesem bekannten Mischfaservlies ist insbesondere, dass es zwar waschbar ist, dass jedoch mit jeder Wäsche ein Teil der Bauschkraft des Mischfaservlieses verloren geht, sodass die Lebensdauer der damit hergestellten Waren beschränkt ist.A disadvantage of this known mixed fiber fleece is, in particular, that although it is washable, part of the bulk of the mixed fiber fleece is lost with each wash, so that the service life of the goods produced with it is limited.
Aufgabe der Erfindung ist es, ein Mischfaservlies zur Verfügung zu stellen, welches über einen längeren Zeitraum seine dem Neuzustand entsprechenden Eigenschaften beibehält sowie ein Verfahren zur Herstellung eines solchen Mischfaservlieses bereitzuhalten. Die Lösung dieser Aufgabe erfolgt in Verbindung mit den Oberbegriffsmerkmalen der Ansprüche 1 und 6 erfindungsgemäß durch die in den kennzeichnenden Teilen derselben Patentansprüche angegebenen technischen Lehren.The object of the invention is to provide a mixed fiber fleece which retains its properties corresponding to the new condition over a longer period of time and to provide a method for producing such a mixed fiber fleece. This object is achieved in connection with the preamble features of claims 1 and 6 according to the invention by the technical teachings specified in the characterizing parts of the same claims.
Dadurch, dass das Mischfaservlies aus einer Mischung von feinen Syn- thetikfasern wie Polyesterfasern und Kapokfasern besteht, wird ein Mischfaservlies zur Verfügung gestellt, welches mit dem Gesamtprodukt zusammen voll waschbar bleibt, wobei der Synthetikfaser-Anteil für den Erhalt der Bauschkraft in dem Mischfaservlies sorgt, wo hingegen der Kapokanteil antibakteriell wirkt und eine Hausstaubmilbenfreiheit Gewähr leistet, sodass das Gesamtprodukt, um den hygienischen Bedürfnissen zu genügen, letztlich nicht so oft gewaschen werden muss wie beispielsweise Bettwaren, die nur aus Synthetikfasern bestehen.Because the mixed fiber fleece consists of a mixture of fine synthetic fibers such as polyester fibers and kapok fibers, a mixed fiber fleece is made available which remains fully washable together with the overall product, the synthetic fiber portion maintaining the bulk in the mixed fiber fleece, where, on the other hand, the kapok portion has an antibacterial effect and guarantees that there is no dust mite, so that the entire product does not have to be washed as often in order to meet the hygienic requirements as bedding that consists only of synthetic fibers.
Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den nachfolgenden Unteransprüchen.Further advantageous embodiments of the subject matter of the invention result with and in combination from the following subclaims.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung sind die Synthetikfasern und die Kapokfasem homogen miteinander vervliest, sodass eine problemlose Weiterverarbeitung möglich wird und die vorteilhaften Eigenschaften des Mischfaservlieses gleichmäßig zur Geltung kommen.According to a particularly preferred embodiment of the invention, the synthetic fibers and the kapok fibers are homogeneously bonded to one another, so that problem-free further processing is possible and the advantageous properties of the mixed fiber fleece come into their own evenly.
Bei einer anderen Ausführungsform des erfinderischen Mischfaservlieses sind einzelne Lagen aus Synthetikvlies oder Kapokvlies mit weiteren einzelnen Lagen schichttechnisch miteinander vervliest, wobei zwei oder mehr Lagen übereinander angeordnet sein können. Solche Lagen können nicht nur aus reinem Polyestervlies oder reinem Kapokvlies sondern auch aus miteinander vervliesten Synthetik- und Kapokfasern bestehen, sodass jeder gewünschte Anforderung an das Mischfaservlies entspro- chen werden kann.In another embodiment of the inventive mixed fiber fleece, individual layers of synthetic fleece or kapok fleece with further individual layers are nonwoven with one another in terms of layer technology, two or more layers can be arranged one above the other. Such layers can consist not only of pure polyester fleece or pure kapok fleece but also of synthetic and kapok fibers which are fleece-bonded to one another, so that any desired requirements for the mixed fiber fleece can be met.
Der Anteil der Kapokfasern an dem gesamten Mischfaservlies kann dabei so klein sein, dass er gerade noch die Hausstaubmilbenfreiheit garantieren kann oder auch beliebig größer gewählt werden, je nach dem, wie hoch die Anforderungen daran gestellt werden oder wie die Gesamteigenschaften des Mischfaservlieses eingestellt werden sollen.The proportion of kapok fibers in the total mixed fiber fleece can be so small that it can just guarantee the absence of house dust mites or can be chosen arbitrarily larger, depending on how high the requirements are or how the overall properties of the mixed fiber fleece should be adjusted.
Die Synthetikfasern aus Polyester (PES) können dabei wahlfrei aus Vollfasern, Hohlfasern und/ oder aus 3-D-Fasern bestehen.The synthetic fibers made of polyester (PES) can optionally consist of solid fibers, hollow fibers and / or 3-D fibers.
Alles in allem wird ein Mischfaservlies zur Verfügung gestellt, Welches bei gleicher Dicke wie ein bekanntes Mischfaservlies aus Schafschurwolle und Kapok deutlich leichter ist und so, beispielsweise bei der Verarbeitung als Füllmaterial für Bettdecken, ein erheblich luftigeres und ange- nehmeres Gefühl bei einem Benutzer erzeugt als das bekannte, sehr viel schwerere Mischfaservlies aus reinen Naturprodukten.All in all, a mixed fiber fleece is made available which, with the same thickness as a known mixed fiber fleece made of sheep's wool and kapok, is significantly lighter and thus, for example when processing as a filling material for duvets, creates a considerably more airy and pleasant feeling for a user than the well-known, much heavier mixed fiber fleece made from pure natural products.
Zur Herstellung des Mischfaservlieses werden die zu vermischenden Fasern vorab mechanisch in einem vorher bestimmten Mischungsverhältnis aufgelockert. Diesen Vorgang erledigt ein Ballenöffner, bei dem die Fasern über ein Nadellattentuch gegen eine entgegenlaufende, mit Nadeln besetzte Walze transportiert werden. Die Nadeln der Walze kämmen die überschüssigen Fasern aus dem Nadellattenband und werfen sie da- durch zurück zu den noch zu öffnenden Fasern, wodurch eine gleichmäßige Beschickung der nächsten Offneranlage ermöglicht wird.To produce the mixed fiber fleece, the fibers to be mixed are loosened beforehand mechanically in a predetermined mixing ratio. This process is carried out by a bale opener, in which the fibers are transported over a needle lattice cloth against an opposing roller with needles. The needles on the roller comb the excess fibers from the needle slat band and throw them there. through back to the fibers that are still to be opened, which enables a uniform loading of the next opener system.
Die vorgeöffneten Fasern werden anschließend zu der als Feinöffner ausgebildeten nächsten Öffneranlage transportiert. Dieser Feinöffner dienst als zweite Faseröffnungseinrichtung. Die vorgemischten Fasern werden hier über mehrere mit Sägezahndraht garnierten Walzen, die unterschiedliche Durchmesser und teilweise entgegengesetzte Drehrichtungen haben, geschickt, damit die Fasern mehr oder weniger parallel zueinander laufen und etwaige Batzen oder Büschel aufgelöst werden. Dies ist notwendig, da die einzelnen Fasern der nachfolgenden lufttechnischen Anlage unbedingt separiert zugeführt werden müssen.The pre-opened fibers are then transported to the next opening system designed as a fine opener. This fine opener serves as a second fiber opening device. The premixed fibers are sent here over several rollers topped with sawtooth wire, which have different diameters and sometimes opposite directions of rotation, so that the fibers run more or less parallel to each other and any chunks or tufts are dissolved. This is necessary because the individual fibers of the subsequent ventilation system must be fed separately.
Die lufttechnische Anlage besteht aus zwei verschiedenen, ca. 80-200 m langen spezialbeschichteten Kunststoffschläuchen, die spiralförmig in einem Turm angeordnet sind. Des Weiteren gehören zu dieser Anlage zwei speziell für dieses Verfahren konstruierte Saugventilatoren, die die Fasern mit einer genau bemessenen Luftgeschwindigkeit aus dem Feinöffner durch den Turm befördern. Hierbei erfolgt die vollständig homo- gene Vermischung, da sich die beiden Fasern in dem Luftstrom des Schlauches verbinden und durch eine bestimmte Reibung, die durch die Strömungsgeschwindigkeit erzielt wird, zusammen fügen.The ventilation system consists of two different, approximately 80-200 m long specially coated plastic hoses, which are arranged spirally in a tower. This system also includes two suction fans specially designed for this process, which transport the fibers out of the fine opener through the tower at a precisely measured air speed. The completely homogeneous mixing takes place here, since the two fibers combine in the air flow of the hose and are joined together by a certain friction, which is achieved by the flow velocity.
Einzig dieses Verfahren ermöglicht eine 100%ig homogene Vermischung der beiden unterschiedlichen Faserarten. This method alone enables 100% homogeneous mixing of the two different types of fibers.
