Definitions

  • a generic textile substrate is known (EP-A-0 356 708), in which the proportion of natural Fibers, especially wool and ramie, between 65 and 85% by weight lies.
  • Such substrates are characterized by excellent Ability to absorb and discharge water vapor and Water, which makes them particularly suitable for seat covers, in particular references to long-term use without interruption Seating such as car and airplane seats, wheelchairs, Office chairs etc. are suitable because of the good Prevents moisture dissipation from the tissue surface the seat cover feels damp and the Seating comfort suffers.
  • Ramie fiber if they are in sufficient concentration - at least 15 wt .-% - is present in the substrate. This was because of her chemical composition - degummed ramie consists in essential from cellulose - was not to be expected. Although it had been shown that Ramie played a role in the Transfer of water from wool to synthetic fiber how polyester plays, but that would also be moderate explain the hydrophilic properties of the fiber surface been that has no basis for water transportation over deliver longer distances.
  • the substrate according to the invention consists of at least 40% by weight wool and at least 15% by weight degummed Ramie, the sum of the proportions of wool and Ramie being more than 85% by weight. Otherwise there is preferably made exclusively from substances that rot, so that it is without Restriction is compostable. Even among these Conditions can vary with regard to Requirements. For example, it can be used for Prevention of static charge metal fibers or wire, less than 5% by weight. Will you selected accordingly, they oxidize under suitable Conditions and rot together with the rest Components. The use of elastic fibers is also quite possible since their share if they don't rot such as B.
  • Elastic fibers can e.g. B. be incorporated into the substrate by individual Threads made entirely of such material or an im essential yarn consisting of ramie, for example in the weft of a fabric with twisted elastic fibers.

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.
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.
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.
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.
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.
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.
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.
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,
Fig. 1
ein Gewebe,
Fig. 2
eine Schussraschel und
Fig. 3
Malimo.
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, weniger 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 weniger als 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.
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.
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.
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.
Bei einer Messung der Steighöhe zeigte das beschriebene Gewebe Werte, wie sie für ein gut wasserableitendes Substrat typisch sind, nämlich:
Kette Schuss
nach 1 Stunde ∼ 15 cm ∼ 15 cm
nach 3 Stunden > 25 cm > 25 cm
Figuren 2 und 3 zeigen weitere typische Substrate, Figur 2 Schussraschel und Figur 3 Malimo, die gleichfalls in einer der oben beschriebenen Weisen zusammengesetzt sein können.
