Abstract

It contains a light-transmitting synthetic fibre and stable fluorescent material which is added to the fibre. This fibre can be employed in substances which serve at night to catch the eye and can be used as safety clothing.

Description

Lumineszierende Faser Luminescent fiber

Die Erfindung betrifft eine lumineszierende Faser.The invention relates to a luminescent fiber.

Diese kann in Stoffe eingewebt werden, welche Licht aussenden.This can be woven into fabrics that emit light.

Durch die Erfindung soll die Aufgabe gelöst werden, eine lumineszierende Faser zu schaffen, indem beständig fluoreszierendes Material in eine lichtübertragende synthetische Faser eingearbeitet wird.The object of the invention is to be achieved, a luminescent Create fiber by turning resistant fluorescent material into a light transmitting material synthetic fiber is incorporated.

Diese Aufgabe wird durch die kennzeichnenden Merkmale von Patentanspruch 1 gelöst.This object is achieved by the characterizing features of patent claim 1 solved.

Eine Ausführungsform der Erfindung ist in den Zeichnungen dargestellt. Darin zeigen Fig. 1 eine perspektivische Ansicht einer lumineszierenden Faser gemäß der Erfindung und Fig. 2 eine schematische Darstellung eines Spinnverfahrens.An embodiment of the invention is shown in the drawings. 1 shows a perspective view of a luminescent fiber according to FIG of the invention and FIG. 2 is a schematic representation of a spinning process.

Die lumineszierende Faser gemäß der Erfindung kann aus polymeren Materialien, wie z.B. Polypropylen, Polyester, Nylon, Acryl und Reyon, welche transparent bzw. lichtdurchlässig oder durchsichtig sind, hergestellt sein.The luminescent fiber according to the invention can be made of polymeric materials, such as polypropylene, polyester, nylon, acrylic and rayon, which are transparent or translucent or translucent, be made.

Das beständig fluoreszierende Material, welches in der Erfindung verwendet wird, beinhaltet Zinksulfid, Kalziumsulfid, Strontiumsulfid etc., welche sichtbare Strahlen aussenden. Sie werden in Form von feinem Pulver von ungefähr 14 /um Größe verwendet. Nebenbei beinhaltet das fluoreszierende Material, wie es in dieser Erfindung verwendet wird, phosphoreszierende Materialien.The persistent fluorescent material used in the invention is, includes zinc sulfide, calcium sulfide, strontium sulfide etc., which are visible Send out rays. They come in the form of fine powder of approximately 14 µm in size used. Incidentally, includes the fluorescent material as in this invention used phosphorescent materials.

Fig. 1 zeigt eine lumineszierende Faser 1, welche aus einer synthetischen Faser 2 und einem fluoreszierenden Material 3 gebildet ist. In diesem Beispiel ist die synthetische Faser 2 aus Polypropylen hergestellt und das fluoreszierende Material ist Zinksulfid, wobei der Gehalt an Zinksulfid 20 Gewichtsprozent basierend auf Polypropylen beträgt. Der Gehalt an Zinksulfid kann im Bereich von 15 bis 25 Gewichtsprozent richtig eingestellt werden, mit einer zufriedenstellenden lumineszierenden Wirkung und Faserfestigkeit. Wenn der Gehalt niedriger als 15 Gewichtsprozent ist, ist die Menge an ausgestrahltem Licht ungenügend; und wenn er höher als 25 Gewichtsprozent ist, wird die sich ergebende Faser brüchig und dem daraus hergestellten Gewebe fehlt es an Festigkeit.Fig. 1 shows a luminescent fiber 1, which consists of a synthetic Fiber 2 and a fluorescent material 3 is formed. In this example is the synthetic fiber 2 made of polypropylene and the fluorescent material is zinc sulfide, the content of zinc sulfide being 20 weight percent based on Polypropylene. The zinc sulfide content can range from 15 to 25 percent by weight properly adjusted, with a satisfactory luminescent effect and fiber strength. If the content is less than 15% by weight, that is Insufficient amount of emitted light; and if it is higher than 25 percent by weight is, the resulting fiber becomes brittle and the fabric made from it is lacking it in strength.

Die lumineszierende Faser 1, welche den oben beschriebenen Aufbau hat, wird in eine Vielzahl von Stoffen eingewebt, welche auf eine Bes-trahlung mit Licht, Licht für eine lange Zeitdauer aussenden. Solche Stoffe können in Kleidungsstücke eingesetzt werden, welche in der Nacht als Blickfang dienen und als Sicherheitskleidung verwendbar sind.The luminescent fiber 1 having the structure described above is woven into a variety of fabrics that are irradiated with Send out light, light for a long period of time. Such substances can be found in clothing be used, which serve as eye-catchers at night and can be used as safety clothing.

Die lumineszierende Faser 1 nach der Erfindung kann durch einfaches Hinzufügen eines fluoreszierenden Materials 3 zu dem gewöhnlichen Spinnverfahren für synthetische Fasern hergestellt werden. Fig. 2 zeigt das Schmelz-Spinnverfahren zum Herstellen der lumineszierenden Faser nach der Erfindung. Gemäß diesem Verfahren werden Polypropylenkügelchen 6 und Zinksulfid 3 im oben erwähnten Gewichtsverhältnis einer Mischkammer 5 zugeführt, welche durch eine Heizung 7 erhitzt wird. Die Schmelze wird durch eine Pumpe 8 aus einer Düse 9 herausgedrückt. Die extrudierten Endlosfäden 10 (16 Denier in diesem Beispiel) werden gekühlt und erstarren, während sie durch einen Kühlzylinder 11 laufen und schließlich von einem Wickler 12 aufgenommen werden.The luminescent fiber 1 according to the invention can by simply Adding a fluorescent material 3 to the ordinary spinning process for synthetic fibers. Fig. 2 shows the melt-spinning process for making the luminescent fiber of the invention. According to this procedure becomes polypropylene beads 6 and zinc sulfide 3 in the above-mentioned weight ratio a mixing chamber 5, which is heated by a heater 7. The melt is pressed out of a nozzle 9 by a pump 8. The extruded filaments 10 (16 denier in this example) will cool and solidify as it passes through run a cooling cylinder 11 and are finally taken up by a winder 12.

Da Zinksulfid bis 10000 C Hitze stabil ist, wird seine fluoreszierende Eigenschaft nicht angegriffen, wenn es unter Erhitzung mit Polypropylenkügelchen 6 gemischt wird.Since zinc sulfide is stable up to 10000 C heat, it becomes fluorescent Property not attacked when heated with polypropylene beads 6 is mixed.

Der Umfang der Erfindung ist nicht auf das oben erwähnte Beispiel beschränkt. Sie kann auch zur Herstellung von lumineszierenden Fasern mit leinenartiger Beschaffenheit bzw. leinenartigem Finish verwendet werden. In einem solchen Verfahren wird ein fluoreszierendes Material zu der Reyon-Lösung zugefügt, in welche Wolle,- Baumwolle- oder synthetische Fasern getaucht werden, um Leinenbeschaffenheit bzw. -finish nachzuahmen. Außerdem kann ein lumineszierender Stoff durch Beifügen eines fluoreszierenden Materials zum Bindemittel eines nichtgewebten Stoffs hergestellt werden.The scope of the invention is not limited to the example mentioned above limited. You can also use it to make luminescent fibers with linen-like Texture or linen-like finish can be used. In such a process if a fluorescent material is added to the rayon solution, in which wool, Cotton or synthetic fibers are dipped in order to improve the quality of the linen or -finish to imitate. It can also be a luminescent substance by Adding a fluorescent material to the binder of a nonwoven fabric getting produced.

Die Erfindung hat somit die vorteilhafte Wirkung, daß sie Stoffen durch Einarbeiten von lichtübertragenden synthetischen Fasern mit einem beständig fluoreszierenden Material eine lumineszierende Eigenschaft verleiht.The invention thus has the advantageous effect that it substances by incorporating light-transmitting synthetic fibers with a resistant gives fluorescent material a luminescent property.
