Abstract

The fibres in the material are bonded together at their crossing points by the application of heat to give local fibre welding points. The application of heat is computer controlled, in an intermittent action, delivered at various angles to intersect. The heat can be delivered by electro-magnetic radiation as coherent light beams, or a beam of electrically charged particles such as electrons. The fibres in the material are such that they will melt together with difficulty, or not at all, at their contact points, with added thermoplastic filaments with a low melting point to give the fused bondings. The process allows a fabric to be developed by bonding warps and wefts at their crossing points without weaving them together.

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrich-The invention relates to a method and a device

tung zur Herstellung eines textilen Plächengeblldes mittels F aserverschmelzung durch punktuelle Wärmewirkung.device for the production of a textile sheet structure by means of fiber fusion through punctual heat effects.

Es ist bekannt, daß die konventionellen Verfahren der Web-und Stricktechnik mechanisch aufwendige Vorrichtungen erf3rdern. Neuere Verfahren nutzen Preßluft oder Wasser zum Einschießen der Fäden. Es ist ferner bekannt, daß Gewebe zum Befestigen mittels Hitze und Druck aus geeigneten thermoplastischen Garnen gewebt werden, die zu Markierungszwecken auf anderen zu waschenden oder zu reinigenden Geweben aufgebracht werden. Beispiele sind in AS 1168838, AS 1220799 und OS1535573 beschrieben. Weiter ist bekannt, daß neben der optischen Fehlerprüfung textiler Flächengebilde (z.B.It is known to use the conventional methods of weaving and knitting mechanically complex devices require. Newer processes use compressed air or water to shoot the threads. It is also known that tissue for fastening are woven by means of heat and pressure from suitable thermoplastic yarns that Applied for marking purposes on other fabrics to be washed or cleaned will. Examples are described in AS 1168838, AS 1220799 and OS1535573. Further it is known that in addition to the optical defect check of textile fabrics (e.g.

OS 2707538, OS 2836280) auch kohärente Abtastvorrichtungen zur Inspektion von Textilmaterial ( OS 2707544 ) beschrieben sind. Auf der "Trend Textil '80 Innovationsausstellung der Textilindustrie Deutsches Museum 10.5.-30.6 980" sind keine neuen Verfahren vorgestellt worden, die nicht mit konventionellen, bekannten Web- oder Stricktechniken arbeiten.OS 2707538, OS 2836280) also coherent scanning devices for inspection of textile material (OS 2707544) are described. At the "Trend Textil '80 innovation exhibition of the textile industry Deutsches Museum 10.5.-30.6 980 "are not new processes that have not been presented using conventional, well-known weaving or knitting techniques work.

Der Erfindung liegt die Aufgabe zugrunde, eine mechanisch vereinfachte Herstellung textiler Flächengeüilde zu ermöglichen, wobei die bei der Webtechnik als Ketten- und Schußgarne bezeichneten Fasern nicht verwoben sondern durch lokales Verschmelzen in Berührungsbereichen der Fasern aufgrund punktueller Wärmewirkung verbunden werden.The invention is based on the object of a mechanically simplified To enable the production of textile surface structures, with weaving technology Fibers called warp and weft yarns are not interwoven but by local fibers Fusion in contact areas of the fibers due to localized heat effects get connected.

Die Wärmewirkung an den Orten gewwünschter Verschmelzungen der Fasern wird mit geeigneten Mitteln erreicht, die die zu verbindenden Fasern im Berührungsbereich lokal erhitzen und die Fasern punktuell verschmelzen. Die geeigneten Mittel kommen nach einer weiteren Ausbildung der Erfindung aus verschiedenen Raumwinkeln und treffen sich in einem Schnittpunkt, im Berührungsbereich der Fasern. Nach einer weiteren Ausgestaltung der Erfindung treffen die geeigneten IXittel diskontinuierlich zu vorgegebenen Zeitpunkten an den vorgesehenen Verbindungsstellen ein, wo sich gleichzeitig die zu verschmelzenden Fasern berühren müssen. Die Steuerung der Mittel und des Fasertransports erfolgt durch einen Computer.The heat effect at the locations of desired fusions of the fibers is achieved with suitable means that the fibers to be connected in the contact area Heat locally and fuse the fibers at certain points. The appropriate means come according to a further embodiment of the invention from different solid angles and meet at an intersection, in the contact area of the fibers. After another According to the invention, the suitable agents apply discontinuously predetermined times at the designated connection points, where at the same time touch the fibers to be fused. Controlling the middle and the fiber transport is done by a computer.

Die Mittel bestehen aus gerichteter elektromagnetischer Strahlung - z.B. aus kohärenten Lichtstrahlen aus Lasern -oder aus einem bzw. mehreren Strahlen elektrisch geladener Teilchen - z.B. Elektronen - . In einer weiteren Ausgestaltung der Erfindung wird die Herstellung textiler Flächengebilde aus Fasern mit solch hohem Schmelzpunkt, der ein Verschmelzen in Berührungsbereichen - z.B. durch Aufschmelzen zu großer Bereiche aufgrund der erforderlichen großen Energie zufuhr - wesentlich erschwert oder unmöglich macht, durch den Einsatz eines zusätzlichen thermoplastischen Fadens mit niedrigerem Schmelzpunkt ermöglicht, dessen Schmelzgut die Verbindung zwischen den lasern herstellt.The means consist of directed electromagnetic radiation - e.g. from coherent light beams from lasers - or from one or more beams electrically charged particles - e.g. electrons -. In a further embodiment the invention is the production of textile fabrics from fibers with such high melting point, which fuses in contact areas - e.g. by melting too large areas due to the large amount of energy required - essential made difficult or impossible by the use of an additional thermoplastic Thread with a lower melting point enables its melting material to make the connection between the lasers.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die in der bisherigen Web- und Stricktechnik notwendigerweise mechanisch bewegten Teile zu wesentlichen Teilen durch nichtmechanische Elemente ersetzt werden. Die Steuerung der nichtmechanischen und der verbliebenen mechanischen Teile erfolgt durch einen Computer.The advantages achieved with the invention are in particular: that those in the previous weaving and knitting technology necessarily moved mechanically Parts are largely replaced by non-mechanical elements. the Control of the non-mechanical and the remaining mechanical parts takes place through a computer.
