Description
Die Erfindung betrifft einen Zwirn, ein Gewebe aus Zwirn sowie die Verwendung des Gewebes gemäss den Oberbegriffen der unabhängigen Patentansprüche. The invention relates to a twisted yarn, a fabric of twine and the use of the Fabric according to the preambles of the independent claims.
In der Textilindustrie wird mit dem Vorgang "Pillen" oder "Pillenbildung" (englisch "pilling") die durch Scheuern hervorgerufene, unerwünschte Bildung kleiner Knötchen auf Wirk-, Strick- und Webwaren bezeichnet. In besonderem Masse tritt das Problem des Pillens bei stark beanspruchten Bezugstoffen für Sitzmöbel in öffentlichen Verkehrsmitteln wie z.B. Flugzeugen, Eisenbahnen und Omnibussen in Erscheinung. Zum einen müssen solche Bezugstoffe eine Vielzahl von unterschiedlichen und teilweise sogar gegensätzlichen technischen Anforderungen erfüllen, wie u.a. Dauerhaftigkeit, Farbechtheit, Formbeständigkeit, Krumpfechtheit, Verschleissfestigkeit, Flammfestigkeit usw. Zum anderen müssen solche Bezugstoffe auch grossen Anforderungen in ästhetischer Hinsicht genügen, da sie in einem erheblichen Ausmass das Ambiente in den Verkehrsmitteln bestimmen. Gediegene, ästhetisch ansprechende Textilstoffe sorgen für ein gefälliges Ambiente in den Fahrgastzellen von öffentlichen Verkehrsmitteln, während abgenutzte, z.B. durch Pillen verunstaltete Textilien einen schäbigen Eindruck vermitteln, der sich mitunter marktschädigend für die Betreiber der Verkehrsmittel auswirken kann Ein Faden für Sitzmöbel in Verkehrsmitteln ist aus dem Dokument JP 05177067-A bekanntIn the textile industry, the process of "pilling" or "pilling" (English "pilling") referred to by the scrubbing, undesirable formation of small nodules on knitted , knitted and woven goods referred. In particular, the problem of pilling occurs in heavily stressed upholstery fabrics for seating in public transport such as aircraft, railways and buses. On the one hand, such upholstery materials must meet a variety of different and sometimes even conflicting technical requirements, such as durability, color fastness, dimensional stability, shrinkage resistance, wear resistance, flame resistance etc. On the other hand, such upholstery materials must also meet great aesthetic requirements, since they result in a considerable Extent determine the ambience in the means of transport. Solid, aesthetically pleasing fabrics create a pleasing ambience in the passenger compartments of public transport, while worn, eg blemished by pills textiles give a shabby impression, which can sometimes harm the market of the market means a thread for furniture in the transport is from the Document JP 05177067-A is known
Zur Verminderung des Pillens sind zwar sogenannte Anti-Pilling-Ausrüstungen von Textilien und/oder bestimmte Variationen in der Zusammensetzung von Synthetikfasern bekannt. Das Problem des Pillens ist jedoch insbesondere für Gewebe, die zur Verwendung als Bezugstoffe für Passagiersitze in Flugzeugen vorgesehen sind, nicht befriedigend gelöst. Aufgrund des Pillens müssen solche Bezugstoffe oft vorzeitig ersetzt werden, obwohl sie ausser dem Erfordernis der Pillresistenz alle übrigen an sie gestellten technischen Anforderungen erfüllen.To reduce the pill are so-called anti-pilling equipment of textiles and / or certain variations in the composition of synthetic fibers known. The problem of pilling, however, is particularly for tissues intended for use as Fabrics for passenger seats in aircraft are not satisfactorily solved. Because of the pill, such upholstery often needs to be replaced prematurely, although it does except for the requirement of pill resistance, all other technical requirements made of them Meet requirements.
Aufgabe der Erfindung ist die Angabe eines insbesondere zur Verwendung als Bezugstoff für Sitzmöbel geeigneten Gewebes und eines Garns zur Herstellung eines solchen Gewebes, welches das Problem des Pillens vermindert. The object of the invention is the disclosure of a particular for use as a cover fabric for seating furniture suitable fabric and a yarn for producing such Tissue alleviating the problem of pilling.
Die Lösung der Aufgabe ist durch die Merkmale der unabhängigen Ansprüche definiert. Gemäss der Erfindung zeichnet sich ein durch Zusammendrehen von wenigstens zwei Garnen gebildeter Zwirn dadurch aus, dass wenigstens eines der beiden Garne ein Wollfasern und Polyamid-Endlosfasern aufweisendes Crespinogarn ist. Ein Gewebe gemäss der Erfindung zeichnet sich dadurch aus, dass ein wesentlicher Anteil des Gewebes aus einem erfindungsgemässen Zwirn gefertigt ist, wobei dieser Gewebeanteil grösser als 30 Gew.% ist.The solution of the problem is defined by the features of the independent claims. According to the invention, it is characterized by the twisting together of at least two Yarn yarn formed by that at least one of the two yarns Wool fibers and polyamide continuous fibers Crespinogarn is. A fabric according to The invention is characterized in that a substantial proportion of the tissue a twisted yarn according to the invention is produced, this fabric proportion being greater than 30% by weight.
Das Wort "Garn" wird im Zusammenhang mit der vorliegenden Beschreibung und den Ansprüchen als Sammelbegriff für alle linienförmigen textilen Gebilde benutzt. Der Ausdruck "einfaches Garn" wird zur eindeutigen Abgrenzung gegenüber gefachten Garnen oder Zwirnen benutzt. Einfache Garne können Spinnfasergarne (d.h. Garne aus einer Vielzahl von zusammengesponnenen Stapelfasern) oder Filamentgarne (d.h. Garne aus einer oder mehreren Endlosfasern bzw. Filamenten) sein. "Zwirn" ist der Sammelbegriff für alle linienförmigen textilen Gebilde, die durch Zusammendrehen einfacher Garne oder/und Zwirne gleicher oder verschiedener Art entstanden sind. Zwei oder mehr Garne, die lediglich zusammen gespult, jedoch nicht miteinander verdreht sind, werden als "gefachte Garne" bezeichnet.The word "yarn" is used in connection with the present description and the Claims used as collective term for all linear textile structures. Of the The term "simple yarn" becomes a clear distinction from plied yarns or twisting. Simple yarns can be spun yarns (i.e., yarns from a Plurality of staple spun staple fibers) or filament yarns (i.e., yarns) one or more continuous fibers or filaments). "Twine" is the collective term for all linear textile structures produced by twisting single yarns and / or Twists of the same or different kind have arisen. Two or more yarns that only spooled together, but not twisted together, are called "gefachte Yarns ".
"Crespinogarne" sind Garne, die durch Verspinnen eines Filamentgarns mit Stapelfasern gebildet sind. Sie wurden als Alternative Zwirnen aus Stapelfasern wie z.B. Wolle, Baumwolle, Leinen u.ä. entwickelt, um einige spezifische Nachteile von solchen Zwirnen zu vermeiden, ohne gleichzeitig auf andere spezifische Vorteile von Zwirnen verzichten zu müssen. So weisen einerseits Crespinogarne ebenso wie Zwirne eine im Vergleich zu einfachen Spinnfasergarnen gleicher Qualität erhöhte Reissfestigkeit auf. Andrerseits lassen sich jedoch Crespinogarne herstellen, die eine feinere Struktur aufweisen als entsprechende Zwirne. Crespinogarne sind deshalb besonders zur Herstellung von feinen Bekleidungsstoffen geeignet."Crespinogarne" are yarns made by spinning a filament yarn with staple fibers are formed. They have been alternatively twisted from staple fibers such as e.g. Wool, Cotton, linen etc. designed to some specific disadvantages of such plying too avoid dispensing with other specific benefits of twisting at the same time have to. On the one hand Crespinogarne as well as Zwirne one compared to simple staple fiber yarns of the same quality increased tear strength. On the other hand However, Crespinogarne can be produced which have a finer structure than corresponding threads. Crespinogarne are therefore especially for the production of fine Clothing fabrics suitable.
Gemäss der Erfindung wird nun in an sich unlogischer Art ein Zwirn durch Zusammendrehen von wenigstens zwei Garnen gebildet, wobei wenigstens eines der beiden Garne ein Crespinogarn ist. In Anlehnung an die Bezeichnung "Crespinogarn" kann ein solcher Zwirn auch als "Crespinozwirn" bezeichnet werden. Überraschenderweise hat sich herausgestellt, dass ein aus einem Crespinozwirn hergestelltes erfindungsgemässes Gewebe eine vergleichsweise hohe Pillresistenz aufweist. Unerwarteterweise hat sich zudem weiter gezeigt, dass ein Gewebe gemäss der Erfindung eine vergleichsweise sehr gute optische Abdeckung gewährleistet. Anhand von Vergleichstests konnte z.B. gezeigt werden, dass ein erfindungsgemässes Gewebe, das aus einem aus zwei identischen Crespinogarnen gebildeten erfindungsgemässen Zweifachzwirn mit der Feinheit Nm 36/2 gefertigt ist, eine bessere optische Abdeckung gewährleistet als ein entsprechendes Gewebe, das aus einem bis auf die Verzwirnung und die Feinheit ansonsten identischen einfachen Crespinogarn mit der Feinheit Nm 17/1 gefertigt ist. Somit bietet das erfindungsgemässe Gewebe trotz einem kleineren spezifischen Flächengewicht die bessere optische Abdeckung als ein entsprechendes konventionelles Gewebe.According to the invention, a thread is now in utterly illogical nature by Compression of at least two yarns formed, wherein at least one of both yarns is a Crespinogarn. In reference to the name "Crespinogarn" can such a thread can also be called a "crespin thread". Surprisingly It has been found that an inventive produced from a Crespinozwirn Tissue has a relatively high Pillresistenz. Unexpectedly, it has become Furthermore, it is further shown that a tissue according to the invention has a comparatively high degree of flexibility good optical coverage guaranteed. On the basis of comparative tests, it was possible, e.g. shown be that a fabric according to the invention, consisting of one of two identical Crespinogarnen formed inventive two-ply twine with a fineness Nm 36/2 is made, a better optical coverage guaranteed as a corresponding Tissues that are otherwise identical except for the twisting and the fineness simple Crespinogarn with the fineness Nm 17/1 is made. Thus, that offers inventive fabrics despite a smaller specific basis weight the better optical coverage than a corresponding conventional fabric.
Die erwähnten Vorteile des erfindungsgemässen Gewebes hinsichtlich der Pillresistenz und der optischen Abdeckung machen die im Vergleich zu entsprechenden herkömmlichen Geweben erhöhten Herstellungskosten insbesondere bei einer Verwendung des Gewebes als Bezugstoff für stark beanspruchte Sitzmöbel bei weitem wett.The mentioned advantages of the inventive fabric in terms of pill resistance and The optical cover make the compared to corresponding conventional Tissues increased production costs, especially when using the tissue as a fabric for heavily used seats far outweighed.
Grundsätzlich können die wenigstens zwei Garne, aus denen der erfindungsgemässe Zwirn gefertigt ist, zwar verschiedenartig sein. Vorzugsweise sind jedoch die wenigstens zwei Garne zueinander gleichartige Crespinogarne, wodurch ein im Vergleich zu einem einfachen Crespinogarn vergleichbarer Feinheit vergleichmässigtes Garn in Form eines Crespinozwirns erhalten wird.In principle, the at least two yarns from which the inventive twisted yarn is made, although be different.
