Abstract

The textile cover for motor vehicle seats and items of furniture takes the form of a fabric which is produced on a warp loom out of wash-shrunk polyester yarn, and has a wear resistance corresponding to more than 50000 revolutions in accordance with DIN EN ISO 12947.

Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruches 1. Ein derartiges Verfahren ist aus der EP 0 305 094 A1 zum Herstellen einer zweischichtigen Strickware bekannt, die mit hohen Temperaturen im Bereich von 130-190°C arbeitet, wodurch chemische Strukturveränderungen des Polymermoleküls hervorgerufen werden.The invention relates to a method according to the preamble of claim 1. Such a method is known from EP 0 305 094 A1 for producing a two-layer knitted fabric which operates at high temperatures in the range of 130-190 ° C, causing chemical structural changes of the polymer molecule become.

Die EP-A2-0 238 950 beschreibt eine flächige Textilware als Warenbahn oder Formteil, das Polyamid-Polyester-Mischfilamentgarne mit großer Bruchkraftdehnung und großer Restdehnung besitzt, und welches für manche Anwendungszwecke im Automobilbereich eingesetzt wird, wie beispielsweise Himmelschalen, Türverkleidungen, Hutablagen oder Armaturentafeln, die durch Verpressen hergestellt werden, wobei die eingepressten Formen voll erhalten bleiben, was ein Verkleben des Textilgutes auf den Formteilen ohne störende elastische Spannung möglich machen soll. In dieser vorbekannten Druckschrift werden jedoch Textilbezüge für Kraftfahrzeugsitze oder Möbelsitze nicht beschrieben, an die besondere Anforderungen gestellt werden. Insbesondere hängt ihre Ansehnlichkeit und Lebensdauer von der Benutzung ab, die durch ein mehr oder weniger starkes Scheuern gekennzeichnet ist. Bei sogenannten Scheuerversuchen nach DIN EN ISO 12947 wurden mit vorbekannten Textilbezügen Scheuerwerte zwischen 25000 und 40000 Touren (Martindale Gerät) erzielt. Nachteilig macht sich insofern eine unzureichende Belastbarkeit bzw. Scheuerfestigkeit bei Textilwaren zur Herstellung von Sitzbezügen und Innenverkleidungen bemerkbar.EP-A2-0 238 950 describes a flat textile fabric or molded article which has polyamide-polyester Mischfilamentgarne with high breaking force and high residual strain, and which is used for some applications in the automotive sector, such as sky shells, door panels, hat racks or dashboards , which are produced by pressing, wherein the pressed-molds are fully preserved, which should make it possible to glue the textile material on the moldings without disturbing elastic tension. However, textile covers for motor vehicle seats or furniture seats are not described in this prior art document to be placed on the special requirements. In particular, their tenderness and life depends on the use, which is characterized by a more or less strong chafing. In so-called scouring tests according to DIN EN ISO 12947 scouring values of between 25,000 and 40000 revolutions (Martindale device) were achieved with previously known textile covers. The disadvantage is in so far an insufficient resilience or abrasion resistance in textile goods for the production of seat covers and interior trim noticeable.

Der Erfindung liegt deshalb die Aufgabe zugrunde, hier Abhilfe zu schaffen und eine Textilware vorzusehen, die auch erhöhten Anforderungen gerecht wird und deshalb eine längere Lebensdauer von Textilbezügen bei ausgezeichneter Ansehnlichkeit beibehält.The invention is therefore based on the object to remedy this situation and to provide a textile product, which also meets increased requirements and therefore maintains a longer life of textile covers with excellent attractiveness.

Erfindungsgemäß wird diese Aufgabe gelöst durch das Verfahren nach Anspruch 1.According to the invention, this object is achieved by the method according to claim 1.

Die erfindungsgemäße erhebliche Steigerung der Scheuertourenzahl, die zu einer deutlich verbesserten Textilware führt, ist überraschenderweise auf die bei 60° bis 65°C geschrumpfte Textilware zurückzuführen, die ihre Länge beim Heisswaschprozeß verringert, da das Garn zusammenspringt und eben schrumpft, jedoch noch "lebendig" bleibt. Man kann davon ausgehen, daß hierdurch kleinere, engere Maschen an der Endware entstehen, welche der Scheuerung weit besser widerstehen, als die bisherigen größeren Maschen aus Normalgarn.The considerable increase in the number of rubles according to the invention, which leads to a significantly improved textile product, is surprisingly attributable to the textile product shrunk at 60 ° to 65 ° C., which reduces its length in the hot washing process, because the yarn collapses and shrinks, but is still "living". remains. It can be assumed that this results in smaller, narrower stitches on the end product, which resist the scrubbing far better than the previous larger stitches of normal yarn.

Das erfindungsgemäß eingesetzte Polyestergarn ist vom Typ PET oder PBT und kann auch in Kombination mit einem oder mehreren Normalgarnen eingesetzt werden. Scheuertourenzahlen von 50000 bis 65000 Touren und mehr nach der erwähnten DIN-Vorschrift können so erreicht werden.The polyester yarn used according to the invention is of the PET or PBT type and can also be used in combination with one or more normal yarns. Scheuerourenzahlen from 50,000 to 65,000 tours and more according to the aforementioned DIN rule can be achieved.

Während die vorbekannte Lehre gemäß EP 0 238 950 eine flächige Textilware für das Verpressen auf Formteilen einsetzt, bei denen bestimmte Dehnungswerte von besonderer Bedeutung sind, sind derartige Dehnungen bei der erfindungsgemäß eingesetzten, bei 60° bis 65°C im Waschprozeß geschrumpften Textilware von untergeordneter Bedeutung. Die erfindungsgemäße Scheuertourenverbesserung ist auf die kleineren, engeren Maschen zurückzuführen, da hier eine geringere Angriffsfläche beim Scheuern vorhanden ist, was eine deutliche Qualitätserhöhung mit sich bringt.While the prior art teaches according to EP 0 238 950 a flat textile product for pressing on moldings, where certain elongation values are of particular importance, such strains are of minor importance in the inventively used, shrunk at 60 ° to 65 ° C in the washing process textile , The Scheuernourenverbesserung invention is due to the smaller, narrower mesh, as here a lower attack surface when scrubbing is present, which brings a significant increase in quality with it.

Bei der erfindungsgemäß auf einer Rundstrickmaschine hergestellten Textilware, sollte der Anteil des Polyestergarns der überwiegende Teil der Textilware sein, also das Grundgestrick bilden. Bezüglich des Gewichtes, der Breite, den Maschenreihen und Maschenstäbchen sind beim erfindungsgemäßen Textilbezug für den Fachmann noch folgende Angaben interessant: Gewicht Breite Maschenreihen Maschenstäbchen 233 gr/qm 160 170 100 oder 140 315 gr/qm 146 180 110 366 gr/qm 120 180 130 In the case of the textile product produced on a circular knitting machine according to the invention, the proportion of the polyester yarn should be the predominant part of the textile product, ie form the basic knit. With regard to the weight, the width, the courses and wales, the following information is of interest to the person skilled in the art for the textile cover according to the invention: Weight width courses wales 233 gr / sqm 160 170 100 or 140 315 gsm 146 180 110 366 gsm 120 180 130

Für den Fachmann dürfte es einleuchten, daß aus der erfindungsgemäß hergestellten Textilware ein Bezug oder dgl. für die unterschiedlichsten Anwendungszwecke gefertigt werden kann. Auch kann abschließend die erfindungsgemäße Textilware noch bei etwa 150°C endfixiert werden, wodurch die Schrumpfung weiter erhöht und die Ware planiert wird.It will be clear to a person skilled in the art that a cover or the like can be manufactured for a very wide variety of applications from the textile product produced according to the invention. Also, finally, the textile fabric according to the invention can be finally fixed at about 150 ° C, whereby the shrinkage is further increased and the goods are leveled.

Nach dem erfindungsgemäßen Verfahren arbeitet die Rundstrickmaschine mit einer Maschenanzahl von 140 Maschenstäbchen/160 mm bei 170 Maschenreihen/10 cm.According to the method of the invention, the circular knitting machine operates with a mesh count of 140 wales / 160 mm at 170 courses / 10 cm.
