Abstract
Description
Es ist ein gattungsgemässes textiles Substrat bekannt (EP-A-0 356 708), bei welchem der Anteil an natürlichen Fasern, insbesonder Wolle und Ramie, zwischen 65 und 85 Gew.-% liegt. Derartige Substrate zeichnen sich durch hervorragende Fähigkeit zur Aufnahme und Ableitung von Wasserdampf und Wasser aus, wodurch sie sich besonders für Sitzbezüge, insbesondere Bezüge auf lange ohne Unterbrechung benützten Sitzgelegenheiten wie Auto- und Flugzeugsitzen, Rollstühlen, Bürostühlen etc. eignen, da durch die gute Feuchtigkeitsableitung von der Gewebeoberfläche verhindert wird, dass sich der Sitzbezug feucht anfühlt und der Sitzkomfort leidet.A generic textile substrate is known (EP-A-0 356 708) in which the proportion of natural fibers, in particular wool and ramie, is between 65 and 85% by weight. Such substrates are distinguished by their excellent ability to absorb and discharge water vapor and water, which makes them particularly suitable for seat covers, in particular covers for long periods of uninterrupted seating such as car and airplane seats, wheelchairs, office chairs, etc., because of the good moisture dissipation The fabric surface prevents the seat cover from feeling damp and the seating comfort from suffering.
Aus der EP-A-0 455 848 sind gattungsgemässe textile Substrate bekannt, bei welchen der Anteil synthetischer Fasern zwischen 45 und 65 Gew.-% liegt und die insbesondere mindestens 40 Gew.-% Wolle und mindestens 5 Gew.-% Ramie enthalten. Im übrigen enthalten sie mindestens 35 Gew.-% natürlicher Fasern, im Normalfall mehr, wodurch sie einer heute sehr aktuellen Anforderung, nämlich der nach guten farblichen Gestaltungsmöglichkeiten, noch besser entgegenkommen.EP-A-0 455 848 discloses generic textile substrates in which the proportion of synthetic fibers is between 45 and 65% by weight and which in particular contain at least 40% by weight of wool and at least 5% by weight of ramie. In addition, they contain at least 35% by weight of natural fibers, normally more, which means that they even better meet a requirement that is very topical today, namely that of good color design options.
Andererseits ergibt sich aus einem hohen Anteil an synthetischen Fasern normalerweise die Konsequenz, dass entsprechende Substrate schlecht entsorgbar sind und aus diesem Grund den zunehmenden Anforderungen an Umweltverträglichkeit nicht in idealer Weise entsprechen.On the other hand, the consequence of a high proportion of synthetic fibers is that the corresponding substrates are difficult to dispose of and therefore do not ideally meet the increasing requirements for environmental compatibility.
Es schien auch äusserst zweifelhaft, ob ein weitgehender oder sogar totaler Verzicht auf synthetische Fasern nicht die gestalterischen Möglichkeiten des Stoffdesigners zu stark einschränken und vor allem die hervorragenden Eigenschaften bekannter gattungsgemässer Textilien bezüglich Wasseraufnahme und -ableitung beinträchtigen würde. Das erste Problem ist weniger gravierend und kann durch entsprechend angepasste, naturnahere Farbgebung umgangen werden. Für den Flüssigkeitstransport erschien es jedoch nach den bisherigen Resultaten unabdingbar, einen verhältnismässig hohen Anteil - mindestens 15 Gew.-% - synthetischer Fasern, vorzugsweise Polyester, vorzusehen, da deren hydrophobe Eigenschaften für den Flüssigkeitstransport über längere Strecken eine notwendige Bedingung darzustellen schienen.It also seemed extremely doubtful whether extensive or even total abandonment of synthetic fibers would not limit the design possibilities of the fabric designer too much and above all the excellent properties of well-known generic textiles in terms of water absorption and drainage. The first problem is less serious and can be avoided by appropriately adapted, more natural coloring. For the liquid transport, however, it appeared to be essential, according to the results so far, to provide a relatively high proportion - at least 15% by weight - of synthetic fibers, preferably polyester, since their hydrophobic properties seemed to be a necessary condition for the liquid transport over longer distances.
Ueberraschenderweise hat es sich jedoch gezeigt, dass die gleiche Funktion durch die Ramiefaser wahrgenommen wird, wenn sie in ausreichender Konzentration - mindestens 15 Gew.-% - im Substrat vorliegt. Dies war aufgrund ihrer chemischen Zusammensetzung - degummierte Ramie besteht im wesentlichen aus Zellulose - nicht zu erwarten gewesen. Zwar hatte sich erwiesen, dass Ramie eine Rolle bei der Uebertragung von Wasser von Wolle zu synthetischer Faser wie Polyester spielt, dies wäre aber auch mit mässig hydrophilen Eigenschaften der Faseroberfläche zu erklären gewesen, die keine Grundlage für Wassertransport über längere Strecken abgeben.Surprisingly, however, it has been shown that the same function is performed by the Ramie fiber if it is present in the substrate in sufficient concentration - at least 15% by weight. This was not to be expected due to their chemical composition - gummed ramie consists essentially of cellulose. Although ramie had been shown to play a role in the transfer of water from wool to synthetic fiber such as polyester, this could also be explained by the moderately hydrophilic properties of the fiber surface, which do not provide a basis for water transport over long distances.
Dass Ramie Wasser auch über längere Strecken zu transportieren in der Lage ist, dürfte auf den erst vor kurzem bekannt gewordenen Umstand zurückzuführen sein, dass die Ramiefasern hohl sind. Sie bilden Röhren, die im Inneren mit einer Längsrillung versehen sind. Dies begründet eine starke Kapillarwirkung, die, so scheint es, für den Langstreckentransport von Wasser verantwortlich ist.The fact that Ramie water is able to transport long distances is probably due to the fact that the Ramie fibers are only recently known. They form tubes with longitudinal grooves on the inside. This creates a strong capillary action, which, it seems, is responsible for the long-distance transport of water.
In jedem Falle bildet die Entdeckung der Fähigkeit der Ramiefaser, Wasser über lange Strecken abzuführen, die Grundlage für eine überraschend einfache Lösung der Aufgabe, ein textiles Substrat für Sitzbezüge zur Verfügung zu stellen, das nicht nur äusserst komfortabel ist, indem es sich auch bei langdauernder ununterbrochener Benutzung unter schwierigen Bedingungen wie hohen Temperaturen und hoher Luftfeuchtigkeit stets trocken anfühlt, sondern auch die Umwelt sehr wenig belastet, insbesondere gut entsorgbar ist und unter geeigneten Bedingungen mit höchstens geringen entsorgungsbedürftigen Rückständen verrottet. Erfindungsgemässe Substrate können im allgemeinen regelrecht kompostiert werden, indem sie zerkleinert und anschliessend aufgehäuft und bei ausreichender Feuchtigkeit und Temperatur gelagert werden.In any case, the discovery of the ability of the Ramie fiber to drain water over long distances forms the basis for a surprisingly simple solution to the task of making a textile substrate available for seat covers which is not only extremely comfortable, since it always feels dry even after long uninterrupted use under difficult conditions such as high temperatures and high humidity, but also has very little pollution, in particular is easy to dispose of and under suitable conditions with at most minimal residues in need of disposal rotted. Substrates according to the invention can generally be composted by crushing them and then piling them up and storing them with sufficient moisture and temperature.
Das textile Substrat kann im übrigen auf verschiedene Weise, als Gewebe oder Gewirk oder Gestrick, insbesondere auch als Raschel oder Malimo ausgebildet sein. Solche Ausführungen sind in den Figuren schematisch dargestellt. Und zwar zeigen, wobei die Schussrichtung jeweils horizontal verläuft,

Das erfindungsgemässe Substrat besteht aus mindestens 40 Gew.-% Wolle und mindestens 15 Gew.-% degummierter Ramie, wobei die Summe der Anteile von Wolle und Ramie mehr als 85 Gew.-% ausmacht. Im übrigen besteht es vorzugsweise ausschliesslich aus Stoffen, die verrotten, so dass es ohne Einschränkung kompostierbar ist. Auch unter diesen Bedingungen kann es im Hinblick auf verschiedenste Anforderungen ausgerüstet werden. Z. B. kann es zur Verhinderung statischer Aufladung Metallfasern oder Draht, vorzugsweise nicht mehr als 5 Gew.-%, enthalten. Werden sie entsprechend ausgewählt, so oxidieren sie unter geeigneten Bedingungen und verrotten so zusammen mit den übrigen Bestandteilen. Auch die Verwendung von Elastic-Fasern ist durchaus möglich, da deren Anteil, wenn sie nicht verrotten wie z. B. Lycra® (eingetragenes Warenzeichen der Firma Du Pont de Nemours), sehr tief - auf höchstens 5 Gew.-% - gehalten werden oder sonst verrottendes Material wie Naturkautschuk verwendet werden kann. Elastic-Fasern können z. B. in das Substrat eingearbeitet sein, indem einzelne Fäden ganz aus derartigem Material bestehen oder ein im wesentlichen aus Ramie bestehendes Garn, etwa im Schuss eines Gewebes, mit Elastic-Fasern umzwirnt ist.The substrate according to the invention consists of at least 40% by weight of wool and at least 15% by weight of gummed ramie, the sum of the proportions of wool and ramie making up more than 85% by weight. Otherwise, it preferably consists exclusively of substances that rot, so that it can be composted without restriction. Even under these conditions, it can be equipped to meet a wide range of requirements. For example, to prevent static charge, it may contain metal fibers or wire, preferably not more than 5% by weight. If they are selected accordingly, they oxidize under suitable conditions and thus rot together with the other constituents. The use of elastic fibers is also quite possible, since their share if they do not rot like e.g. B. Lycra® (registered trademark of Du Pont de Nemours), very low - to a maximum of 5% by weight - or other rotting material such as natural rubber can be used. Elastic fibers can e.g. B. be incorporated into the substrate by individual threads made entirely of such material or a yarn consisting essentially of ramie, for example in the weft of a fabric, is twisted with elastic fibers.
Obwohl synthetische Fasern wie Polyester, Polypropylen, Polyamid, Polyacryl oder Aramid in geringen Anteilen nicht sonderlich störend sind, wird im Interesse uneingeschränkter Kompostierbarkeit vorzugsweise auf sie verzichtet, so dass alle verwendeten Fasern - von eventueller Beimischung von Metallfasern abgesehen - tierischer oder pflanzlicher Herkunft sind. Neben Wolle und Ramie, die immer vorhanden sind, eignen sich z. B. Baumwolle, Leinen, Zellwolle und Hanf.Although synthetic fibers such as polyester, polypropylene, polyamide, polyacrylic or aramid are not particularly disturbing in small proportions, they are preferably dispensed with in the interests of unlimited compostability, so that all fibers used - apart from the possible admixture of metal fibers - are of animal or vegetable origin. In addition to wool and ramie, which are always present, z. B. cotton, linen, rayon and hemp.
Sehr günstig ist es, wenn das Substrat ein Mischgarn mit Wolle und Ramie enthält, vorzugsweise eines, das aus ca. 80 Gew.-% Wolle und 20 Gew.-% Ramie besteht. Handelt es sich um ein Gewebe, so kann etwa die Kette oder der Schuss aus einem derartigen Mischgarn bestehen, der Schuss bzw. die Kette hingegen aus anderem Material, z. B. aus reiner Ramie. Bei solchen und anderen Substraten hat es sich als möglich und sogar günstig erwiesen, ausschliesslich Wolle und Ramie zu verwenden und auf andere Beimischungen ganz zu verzichten, wenn sie nicht wegen besonderer Anforderungen nötig sind.It is very favorable if the substrate contains a mixed yarn with wool and ramie, preferably one that consists of approximately 80% by weight wool and 20% by weight ramie. If it is a fabric, the warp or the weft can consist of such a mixed yarn, the weft or the warp, on the other hand, be made of a different material, e.g. B. from pure ramie. With such and other substrates, it has proven possible and even inexpensive to use only wool and ramie and to dispense with other admixtures entirely if they are not necessary because of special requirements.
So zeigt Figur 1 ein erfindungsgemässes Gewebe, dessen Kette aus einem Mischgarn 1 mit 80 Gew.-% Wolle und 20 Gew.-% Ramie gebildet ist, während der Schuss aus Ramiefäden 2 besteht. Geeignete Ramie-Fasern werden z. B. unter dem Namen Firon® von der Firma Fischer Dottikon AG, CH-5606 Dottikon vertrieben. Insgesamt ergibt dies einen Anteil an Wolle von 52 Gew.-% und an Ramie von 48 Gew.-%. Natürlich sind auch andere Zusammensetzungen möglich wie weiter oben beschrieben.1 shows a fabric according to the invention, the warp of which is formed from a mixed yarn 1 with 80% by weight of wool and 20% by weight of ramie, while the weft consists of ramie threads 2.
