Abstract

Process for producing beflocked sheet materials consisting of a film-forming polymer layer and an adherent short fibre layer (flock), characterised in that a liquid polymerisable monomer or oligomer is applied to a carrier belt and the layer of liquid is conventionally beflocked by electrostatic methods and then the monomer is polymerised at room temperature with the aid of high-energy rays. Subsequently the beflocked sheet material then formed is separated from the carrier material.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines beflockten Flächengebildes, wobei abweichend von den bisher bekannten Methoden von einem niedermolekularen Trä­ germaterial ausgegangen wird, das erst nach der Beflockung ohne thermische Behandlung zu einem filmbildenden Substrat polymerisiert wird.The invention relates to a method of manufacture of a flocked fabric, deviating from the previously known methods of a low molecular weight Germ material is assumed that only after the flocking without thermal treatment to a film-forming substrate is polymerized.

Die übliche Beflockung wird in der Weise durchgeführt, daß ein textiles Substrat mit einem hochmolekularen Kleber in Form einer wäßrigen Dispersion oder einer organischen Lösung beschichtet, anschließend elektrostatisch beflockt und dann die Kleberschicht durch eine Hitzebehandlung getrocknet wird. Danach wird durch eine zweite thermische Behandlung die Flockfaser im Kleber verankert. Die Kurzfasern werden also mit Hilfe eines hochmolekularen Klebers auf dem Textil­ material fixiert. Diese Verfahrensweise ist in der DE-PS 10 81 857 beschrieben.The usual flocking is carried out in such a way that a textile substrate with a high molecular adhesive Form of an aqueous dispersion or an organic solution coated, then electrostatically flocked and then the adhesive layer is dried by heat treatment becomes. After that, a second thermal treatment the flock fiber anchored in the adhesive. The short fibers are with the help of a high molecular adhesive on the textile material fixed. This procedure is in DE-PS 10 81 857.

Eine Weiterentwicklung der Flocktechnik wurde dadurch er­ reicht, daß wie in der DE-PS 34 14 505 beschrieben, kein textiles Substrat zur Herstellung beflockter Flächengebilde mehr nötig ist. Nach diesem Verfahren wird ein hochmolekula­ rer Kleber in Form wäßriger Dispersionen oder in Form von Lösungen in organischen Lösungsmitteln auf einen Zwischen­ träger aufgebracht, elektrostatisch beflockt, getrocknet um das Wasser oder das Lösungsmittel zu verdampfen und in einem weiteren Hitzeprozess die Fasern im Kleber fixiert. An­ schließend wird das beflockte Material vom Zwischenträger abgezogen.He became a further development of flock technology is enough that as described in DE-PS 34 14 505, no textile substrate for the production of flocked fabrics more is needed. After this procedure, a high molecular weight adhesive in the form of aqueous dispersions or in the form of Solutions in organic solvents on an intermediate applied, electrostatically flocked, dried around to evaporate the water or solvent and in one further heat process the fibers are fixed in the adhesive. On the flocked material then closes from the intermediate carrier deducted.

Eine weitere Vereinfachung und Rationalisierung wurde nun erfindungsgemäß dadurch erreicht, daß als Substrat für die Flockfasern keine hochmolekularen Substanzen sondern nieder­ molekulare flüssige Verbindungen eingesetzt werden, die dann erst nach dem Beflocken zu einem Polymerfilm auspolymeri­ siert werden. Die Polymerisation erfolgt bei Raumtemperatur entweder durch Bestrahlen mit Elektronenstrahlen oder mit UV-Licht. Als Trägermaterial wird eine Warenbahn verwendet von der sich das beflockte Flächengebilde leicht trennen läßt, z. B. ein silikonisiertes Papier oder ein Teflonband. Als Trägermaterial kann auch eine PP-, PVC-, PES- oder PA-Folie verwendet werden.A further simplification and rationalization has now been made achieved according to the invention in that as a substrate for the  Flock fibers are not low molecular weight substances but low molecular liquid compounds are used, which then auspolymeri only after flocking to a polymer film be settled. The polymerization takes place at room temperature either by irradiation with electron beams or with UV light. A web is used as the carrier material from which the flocked fabric easily separates lets, e.g. B. a siliconized paper or a Teflon tape. A PP, PVC, PES or PA film can also be used as the carrier material be used.

Um die Trennung der Flockschicht vom Substrat zu erleich­ tern, kann das Substrat mit einem Schmelzkleber beschichtet werden. Die Flockschicht kann dann in der Wärme vom Substrat abgezogen werden.To facilitate the separation of the flock layer from the substrate tern, the substrate can be coated with a hot melt adhesive will. The flock layer can then heat away from the substrate subtracted from.

In manchen Fällen bildet das Monomere auf dem silikonisier­ ten Papier keine zusammenhängende Flüssigkeitsschicht. Es tritt Inselbildung ein. Um dies zu vermeiden kann das sili­ konisierte Papier mit einer geeigneten Polymerschicht, z. B. Ethylcellulose oder Polyvinylbutyral beschichtet werden. Auf diese Schicht kann dann das Monomere gleichmäßig aufgetragen werden. Nach der Bestrahlung und Polymerisation läßt sich die Flockbahn leicht vom silikonisierten Papier abziehen.In some cases the monomer forms on the siliconizer paper has no continuous layer of liquid. It island formation occurs. To avoid this, the sili butted paper with a suitable polymer layer, e.g. B. Ethyl cellulose or polyvinyl butyral can be coated. On this layer can then apply the monomer evenly will. After irradiation and polymerization, pull the flock sheet slightly off the siliconized paper.

Das Aufbringen der Monomerschicht auf das Trägermaterial kann mit einer Rakel, einem Rollstab oder mit einer Auf­ tragswalze erfolgen. Die bei der Polymerisation nicht fi­ xierten Fasern können durch eine Absaugvorrichtung entfernt werden (siehe beiliegende Zeichnung). Die aufgebrachte Mono­ merschicht kann eine Dicke von 10-300 µm vorzugsweise von 50-150 µm aufweisen. Bei Verwendung von aufgeschäumten Monomeren kann die Schichtdicke bis zu 1000 µm betragen.The application of the monomer layer to the carrier material can with a squeegee, a roller bar or with an on support roller. The fi not in the polymerization Fixed fibers can be removed by a suction device (see attached drawing). The angry mono The layer can have a thickness of 10-300 μm, preferably of Have 50-150 microns. When using foamed Monomers can have a layer thickness of up to 1000 µm.

Der Vorteil des neuen Verfahrens besteht u. a. darin, daß für die Fixierung der Flockfasern keine Hitzebehandlung erforderlich ist und kein Wasser bzw. kein organisches Lö­ sungsmittel verdampft werden muß. Es handelt sich um ein neues energiesparendes und schadstoffarmes Verfahren zur Herstellung beflockter Flächengebilde. Die Energieeinsparun­ gen gegenüber den bisherigen Verfahren betragen bis zu 50%.The advantage of the new method is u. a. in that no heat treatment for fixing the flock fibers is required and no water or organic sol  must be evaporated. It's about a new energy-saving and low-pollutant process for Manufacture of flocked fabrics. The energy saving conditions compared to previous methods are up to 50%.

Es war überraschend, daß trotz der Abdeckung der Monomer­ schicht durch die Flockfasern bei der Bestrahlung mit Elek­ tronenstrahlen oder UV-Strahlen eine vollkommene Durch­ härtung der Monomerschicht erreicht wird. Bei Verwendung von Geweben findet auf der Rückseite des Gewebes keine vollstän­ dige Aushärtung des Monomeren statt. Die Elektronenstrahlen bzw. UV-Strahlen werden von einem Gewebe offenbar viel stär­ ker absorbiert als von der Flockschicht.It was surprising that despite the coverage of the monomer layer through the flock fibers when irradiated with elec Tronen rays or UV rays a perfect passage curing of the monomer layer is achieved. When using There is no complete fabric on the back of the fabric curing of the monomer instead. The electron beams or UV rays are obviously much stronger from a tissue ker absorbed than by the flock layer.

Durch Verwendung von Monomeren anstelle von Polymeren Kle­ bern wird eine besonders stabile Verankerung der Flockfasern im entstandenen Polymerfilm erzielt. Das flüssige Monomer umhüllt die Flockfasern in optimaler Weise und das entste­ hende Polymer kann sich beim Kettenwachstum präzise an die Oberflächenstruktur der Fasern anpassen.By using monomers instead of polymers Kle A particularly stable anchoring of the flock fibers is also used achieved in the resulting polymer film. The liquid monomer wraps the flock fibers in an optimal way and the worst polymer can precisely follow the chain growth Adjust the surface structure of the fibers.

Bei der bisherigen Herstellung von beflockten Flächengebil­ den wird durch die Bildung von Dampfblasen beim Trocknen der wasser- oder lösungsmittelhaltigen Kleberschicht kein opti­ maler Kontakt zwischen Fasermaterial und Substrat erreicht.In the previous production of flocked surface structures is caused by the formation of vapor bubbles when drying the water- or solvent-based adhesive layer no opti Painterly contact between the fiber material and the substrate is achieved.

Das beflockte Flächengebilde kann auf der Rückseite mit einer Kleberschicht versehen und auf ein Dehäsivpapier auf­ gebracht werden. Auf diese Weise kann das Flockmaterial wie Haftetiketten oder DC-Fix-Folien auf jede Unterlage übertra­ gen werden.The flocked fabric can on the back with an adhesive layer and on a adhesive paper to be brought. This way the flock material can be like Transfer self-adhesive labels or DC-Fix foils to every surface be.

Das beflockte Flächengebilde kann auch schon bei der Her­ stellung auf der Rückseite mit einer Kleberschicht versehen werden in der Weise, daß ein geeignetes Monomer verwendet wird, das bei der Bestrahlung nicht voll durchpolymerisiert, so daß die Rückseite klebrig bleibt. Eine andere Möglichkeit besteht darin, daß man das Trägerpapier mit einer Kleber­ schicht versieht, dann das Monomere aufträgt und anschlie­ ßend die Beflockung und Polymerisation durchführt. Man er­ hält so das beflockte Material direkt als Abziehfolie auf dem Dehäsivpapier.The flocked fabric can also be used in the manufacture position on the back with an adhesive layer are used in such a way that a suitable monomer is not fully polymerized during the irradiation, so the back stays sticky. Another possibility  consists in that the backing paper with an adhesive layer, then applies the monomer and then eats the flocking and polymerization. Man he thus holds the flocked material directly as a peel-off film the adhesive paper.

Die erfindungsgemäß hergestellten beflockten Flächengebilde haben Samt- bzw. Velour-Charakter und können für dekorative Zwecke eingesetzt werden, z. B. zum Auskleiden und Bekleben von Schmuck- und Geschirrbehältnissen von Koffern, Taschen u. a. Weiterhin kann das Material zur Innenausstattung von Kraftfahrzeugen, als Ersatz für Textiltapeten und als schallisolierendes Material verwendet werden.The flocked fabrics manufactured according to the invention have a velvet or velor character and can be used for decorative purposes Purposes are used, e.g. B. for lining and pasting of jewelry and crockery containers, suitcases, bags u. a. Furthermore, the material for the interior of Motor vehicles, as a replacement for textile wallpapers and as soundproofing material can be used.
