Description

Die Erfindung betrifft flammwidrig ausgerüstete ausgerüstete, flexible Materialien, insbesondere Textilien.The invention relates to flame-retardant finished, flexible materials, in particular textiles.

Bei der Raumausstattung von Hotels, Theatern und Kongreßzentren, bei Bussen und Flugzeugen spielen flammhemmend ausgerüstete Textilien eine große Rolle als präventiver Schutz. Die derzeit für textile Flächengebilde verwendeten Flammschutzmittel bzw. flammwidrigen Ausrüstungen lassen sich in folgende Gruppen einteilen: 1

  • - Carbonisierende und dehydratisierende Mittel, die bei Cellulosefasern, z.B. Baumwolle, zur Abspaltung von Wasser führen, während ein schwer entflammbares Kohlenstoffgerüst zurückbleibt: Derartige Mittel sind als Pyrovatex R und Proban R im Handel. Der Griff der Textilien wird zwar nicht beeinträchtigt, aber meist leidet die Festigkeit.
  • - Es gibt auch ähnliche flammwidrige Ausrüstungen speziell für Wolle.
  • - Unabhängig von der chemischen Natur der Faser werden beispielsweise Krustenbildner verwendet, die die Sauerstoffzufuhr reduzieren. Sie werden aber selten allein eingesetzt und spielen bei Textilien keine große Rolle.
  • - Ähnliches gilt für wasserabspaltende Mittel, z.B. Aluminiumhydroxid, die unter Bildung von Wasserdampf, der als Schutzgas wirkt, Energie verbrauchen. Ihre wirksame Menge zum Schutz eines textilen Materials ist relativ hoch.
  • - Radikalfänger, die die Kettenreaktion der Verbrennung unterbrechen,sind universal einsetzbar und,spielen vor allem bei Kunststoffen eine große Rolle. Es handelt. sich meist um Bromverbindungen bzw. um Kombinationen von Antimontrioxid mit einem Halogenspender.
Flame retardant textiles play a major role in preventive protection when it comes to furnishing hotels, theaters and congress centers, buses and airplanes. The flame retardants or flame retardant equipment currently used for textile fabrics can be divided into the following groups: 1
  • - carbonizing and dehydrating agents which result in cellulose fibers such as cotton, for removal of water, while a flame retardant carbon skeleton remains: Such agents are as P yrovatex R and R Proban commercially. The feel of the textiles is not affected, but the firmness usually suffers.
  • - There are also similar flame retardant equipment specifically for wool.
  • - Regardless of the chemical nature of the fiber, crust formers are used, for example, which reduce the oxygen supply. However, they are rarely used alone and do not play a major role in textiles.
  • - The same applies to water-releasing agents, such as aluminum hydroxide, which consume energy to form water vapor, which acts as a protective gas. Their effective amount for protecting a textile material is relatively high.
  • - Radical scavengers, which interrupt the chain reaction of the combustion, can be used universally and play an important role, especially in plastics. It deals. mostly bromine compounds or combinations of antimony trioxide with a halogen donor.

Sieht man von den Ausrüstungen ab, die jeweils nur auf eine Faser, z.B. Cellulosefasern oder Wolle ansprechen, so ist festzustellen, daß alle anderen Flammschutzmittel den Charakter von Textilien nachteilig verändern. Der Griff wird hart bzw. brettig, und die Fähigkeit Luft und Wasserdampf hindurch zu lassen bzw. Feuchtigkeit auch nur zu transportieren, wird stark beeinträchtigt. Demzufolge leiden die Trageeigenschaften beträchtlich. Der Grund dafür ist insbesondere bei dem Bindemittel zu suchen, das das pigmentförmige Flammschutzmittel fixiert, aber auch das Gewebe verklebt.Apart from the equipment, which is only on one fiber, e.g. If cellulose fibers or wool respond, it should be noted that all other flame retardants adversely affect the character of textiles. The handle becomes hard or boardy, and the ability to let air and water vapor through or even to transport moisture is severely impaired. As a result, the wearing properties suffer considerably. The reason for this is particularly to be found in the binder that fixes the pigment-like flame retardant but also glues the fabric.

Der Erfindung liegt die Aufgabe zugrunde, flexible, insbesondere textile, Materialien in einer Weise flammwidrig auszurüsten, daß gute Trageeigenschaften bei hervorragender Schutzwirkung resultieren. Hierzu gehört auch die Möglichkeit der Verwendung von Flammschutzmitteln, die bisher nicht für Textilien verwendet wurden.The invention has for its object to provide flexible, in particular textile, materials in a flame-retardant manner that good wearing properties result with excellent protection. This also includes the possibility of using flame retardants that have not previously been used for textiles.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Flammschutzmittel auf dem flexiblen Material in statistischer Verteilung oder in einem bestimmten Muster so aufgebracht ist, daß ein wesentlicher Teil der Oberfläche des flexiblen Trägers unbedeckt bleibt.According to the invention, this object is achieved in that the flame retardant is applied to the flexible material in a statistical distribution or in a specific pattern such that a substantial part of the surface of the flexible carrier remains uncovered.

Vorzugsweise wird das Flammschutzmittel in einem bestimmten Muster, insbesondere punktförmig, aufgedruckt. Dieses aufgedruckte Muster des Flammschutzmittels hat zweckmäßig eine Höhe von o,o1 bis 1 mm und einen Durchmesser bzw. eine Breite von o,o5 bis 2 mm, vorzugsweise o,2 bis 1 mm. Durch die Gestaltung des Druckes wird dafür gesorgt, daß das aufgedruckte Muster des Flammschutzmittels nur etwa 2o bis 80 %, vorzugsweise 3o bis 7o % der Oberfläche des flexiblen Trägers bedeckt.The flame retardant is preferably printed in a specific pattern, in particular in the form of a dot. This printed pattern of the flame retardant expediently has a height of 0.1 to 1 mm and a diameter or a width of 0.05 to 2 mm, preferably 0.2 to 1 mm. Due to the design of the pressure is ensured that the printed pattern of the flame retardant only about 2o 0 to 8%, preferably from 3o to 7o% of the surface of the flexible substrate is covered.

Hinsichtlich der verwendbaren Flammschutzmittel unterliegt die Erfindung praktisch keinen Beschränkungen. Es kann sich sowohl um verkohlungsfördernde und feuererstickende als auch sperrschichtbildende Flammschutzmittel handeln. Gut geeignet sind auch die sogenannten Dämmschichtbildner, die Substanzen enthalten, die sich beim Erwärmen schaumig aufblähen, ab 2oo bis 300°C verkohlen, sich dabei verfestigen und ein feinporiges gut isolierendes Polster bilden. Brauchbar sind ferner die für Kunststoffe bekannten Flammschutzmittel, deren flammhemmende Wirkung noch durch sogenannte Synergisten oder bestimmte Weichmacher bzw. die insbesondere bei pigmentförmigen Flammschutzmitteln notwendigen Bindemittel verstärkt werden kann. Auch selbstverlöschende Kunststoffe, insbesondere solche mit höherem Halogengehalt, sind allein oder in Kombination mit anderen bekannten Flammschutzmitteln brauchbar. Zusammenfassend sind also alle Flammschutzmittel,im Rahmen der Erfindung verwendbar, die in Kombination mit dem als Träger dienenden textilen Flächengebilde und untereinander verträglich und. beispielsweise in Römpps Chemie-Lexikon, 8. Aufl., (1981) unter dem Stichwort "Flammschutzmittel" und den hier aufgeführten Literaturstellen beschrieben sind.With regard to the flame retardants which can be used, the invention is practically not subject to any restrictions. Flame retardants that promote carbonization and fire-suffocation as well as barrier layers can be involved. The so-called intumescent layer formers are also very suitable, as they contain substances that foam up when they heat up, carbonize from 2oo to 300 ° C, solidify and form a fine-pored, well-insulating cushion. The flame retardants known for plastics can also be used, the flame retardant effect of which can be enhanced by so-called synergists or certain plasticizers or the binders necessary in particular in the case of pigmented flame retardants. Self-extinguishing plastics, in particular those with a higher halogen content, can also be used alone or in combination with other known flame retardants. In summary, all flame retardants can be used within the scope of the invention, which are compatible with one another in combination with the textile fabric serving as a carrier and. for example in Römpps Chemie-Lexikon, 8th ed., (1981) under the keyword "Flame retardant" and the references listed here.

Soweit das Flammschutzmittel sich nicht selbst zum Druck eignet, sondern beispielsweise pigmentförmig ist und ein Bindemittel erfordert, werden für das Aufdrucken der Flammschutzmittel geeignete, insbesondere polymere, Bindemittel verwendet. Diese gehören chemisch beispielsweise zur Gruppe der Polyurethane, Polyacrylate oder Elastomere. Letztere können auch halogeniert, insbesondere chloriert oder fluoriert, sein. Sehr geeignet sind ferner Scnmelz- kleber auf Basis von Polyamiden, Polyestern oder Äthylen-Vinylacetat-Copolymeren (EVA). Beim Druck liegen die polymeren Bindemittel und die Schmelzkleber meist als Dispersion vor. In dem aufgedruckten Muster verbleiben dann aber nur die polymeren, verfestigten, beispielsweise vernetzten oder vulkanisierten, Bindemittel. Ihr Anteil in dem aufgedruckten Muster des Flammschutzmittels kann 5 bis 2oo, insbesondere 10 bis 5o Gew.%, bezogen auf das Flammschutzmittel, ausmachen.Insofar as the flame retardant is not itself suitable for printing, but is, for example, pigment-shaped and requires a binder, suitable, in particular polymeric, binders are used for printing on the flame retardant. Chemically, these belong to the group of polyurethanes, polyacrylates or elastomers. The latter can also be halogenated, in particular chlorinated or fluorinated. Melting glue based on polyamides, polyesters or ethylene-vinyl acetate copolymers (EVA). When printing, the polymeric binders and hot melt adhesives are usually in the form of a dispersion. However, only the polymeric, solidified, for example crosslinked or vulcanized, binders then remain in the printed pattern. Their share in the printed pattern of the flame retardant may be 5 to 2oo, in particular 1 to 5o 0 wt.%, Based on the flame retardant, make up.

Die Trägerschicht für das flammwidrig ausgerüstete flexible Material nach der Erfindung ist für die meisten Anwendungsgebiete, insbesondere für die Herstellung von Schutzanzügen, in der Regel ein textiles Flächengebilde aus Mineral-, Synthese- oder Naturfasern. Gewebe oder Gewirke werden wegen ihrer geringen Dicke bei hoher Festigkeit besonders bevorzugt. Die Auswahl des Trägertextils richtet sich nach dem gewünschten Verwendungszweck. Im Falle leichter Schutzbekleidung empfiehlt sich ein Verbundwerkstoff bzw. Mischgewebe aus Synthese- oder Naturfasern und Mineralfasern, wobei die Mineralfaserseite mit dem aufgedruckten Muster des Flammschutzmittels versehen wird. Auch die gleichzeitige Verwebung dieser Materialien ist gut geeignet. Die Mitverwendung von schwer entflammbaren bzw. besonders reißfesten Fasern, wie Aramiden (KEVLAR, NOMEX) oder Polyimiden, kann für bestimmte Verwendungszwecke nützlich sein.The backing layer for the flame-retardant flexible material according to the invention is for most areas of application, in particular for the production of protective suits, as a rule a textile fabric made of mineral, synthetic or natural fibers. Woven or knitted fabrics are particularly preferred because of their small thickness and high strength. The choice of the backing textile depends on the intended use. In the case of light protective clothing, a composite or mixed fabric made of synthetic or natural fibers and mineral fibers is recommended, with the mineral fiber side being provided with the printed pattern of the flame retardant. The simultaneous weaving of these materials is also suitable. The use of flame-retardant or particularly tear-resistant fibers, such as aramids (KEVLAR, NOMEX) or polyimides, can be useful for certain purposes.

Das flexible Trägermaterial kann nicht nur einseitig, sondern auch beidseitig bedruckt werden und die Klebewirkung des polymeren Bindemittels vor seiner Verfestigung läßt sich nutzen, um ein Verbundmaterial herzustellen, das zwischen zwei flexiblen, insbesondere luftdurchlässigen Trägerschichten eine unterbrochene Schicht aus dem regelmäßig aufgedruckten Muster des gebundenen Flamm- schutzmittels von bis zu etwa 1 mm Dicke aufweist. Dann liegen beispielsweise diese Noppen des Flammschutzmittels zwischen zwei Bahnen und sind besser geschützt. Dieses Verbundmaterial läßt sich herstellen, indem man unmittelbar nach dem Bedrucken einer Bahn der flexiblen Trägerschicht eine weitere Trägerschichtbahn zulaufen läßt, dann das Verbundmaterial trocknet und durch Einwirkung von Druck und Hitze zusammenkaschiert.The flexible carrier material can be printed not only on one side but also on both sides and the adhesive effect of the polymeric binder before it solidifies can be used to produce a composite material that is between two flexible, in particular air-permeable permeable T rägerschichten a discontinuous layer of the regular printed pattern of the bound F lamb protection by means of up to about 1 mm thickness. Then, for example, these nubs of the flame retardant lie between two webs and are better protected. This composite material can be produced by allowing another substrate layer web to run in immediately after the printing of a web of the flexible carrier layer, then drying the composite material and laminating it together under the action of pressure and heat.

Allgemein geschieht die Herstellung des erfindungsgemäßen flammwidrig ausgerüsteten flexiblen Materials in der Weise, daß eine Paste aus dem beispielsweise pulverförmigen Flammschutzmittel, gegebenenfalls mit flüssigen Flammschutzmitteln, Synergisten oder Weichmachern, einer Lösung oder Dispersion des polymeren Bindemittels und gegebenenfalls üblichen Druckhilfsmitteln durch Rotationssiebdruck auf die flexible Trägerschicht in einem bestimmten Muster aufgetragen, getrocknet und verfestigt wird. Wird das polymere Bindemittel z.B. in Form von Polyurethan- oder Polyacrylatlatices, dem Latex von gegebenenfalls halogenierten Elastomeren; wie Natur-, Synthese- oder Siliconkautschuk, Chloropren oder Fluoropren eingesetzt, dann müssen nach dem Druck die in einem bestimmten Muster aufgetragenen Häufchen oder Dämme des gebundenen Flammschutzmittels zur Entfernung der flüchtigen Latexbestandteile getrocknet werden. Je nach der chemischen Natur des Bindemittels können sie anschließend auch noch Druck und/oder Wärme ausgesetzt werden, um verfestigt, d.h. vernetzt oder vulkanisiert zu werden, sofern sich dabei nicht schon das Flammschutzmittel verändert, z.B. funktionsgemäß zersetzt.In general, the manufacture of the flame-retardant flexible material according to the invention takes place in such a way that a paste made from, for example, powdered flame retardant, optionally with liquid flame retardants, synergists or plasticizers, a solution or dispersion of the polymeric binder and, if appropriate, customary printing aids is applied to the flexible carrier layer by rotary screen printing applied, dried and solidified in a specific pattern. If the polymeric binder is e.g. in the form of polyurethane or polyacrylate latices, the latex of optionally halogenated elastomers; such as natural, synthetic or silicone rubber, chloroprene or fluoroprene, then the piles or dams of the bound flame retardant applied in a certain pattern must be dried to remove the volatile latex components after printing. Depending on the chemical nature of the binder, they can then also be subjected to pressure and / or heat in order to solidify, i.e. to be crosslinked or vulcanized, provided the flame retardant does not change, e.g. functionally decomposed.

Schmelzkleber, insbesondere auf Basis von Polyamiden, Polyestern oder EVA, können außer als Dispersion auch als Trockenpulver eingesetzt werden. Dann müssen die aufgedruckten Häufchen aus Flammschutzmitteln und: - Schmelzkleber unmittelbar nach dem Druck kurz einer Wärmestrahlung ausgesetzt werden, bevor man die bedruckte Bahn zur endgültigen Verfestigung in den sogenannten Trockenkanal fährt.Hot melt adhesives, in particular based on polyamides, polyesters or EVA, can also be used as dry powder in addition to as a dispersion. Then the printed piles of flame retardants and: - Hot melt adhesive must be exposed to heat radiation shortly after printing, before the printed web is driven into the so-called drying tunnel for final consolidation.

Die sich beim Erwärmen schaumig aufblähenden Dämmschichtbildner werden in einem solchen Muster bzw. Abstand der Flammschutzmittelpunkte aufgedruckt, daß das Druckmuster unter der Hitzeeinwirkung zu einer geschlossenen Schutzschicht zusammenschäumt, bevor der textile Träger erheblichen Schaden erleidet bzw. seine Festigkeit verliert. Einmal vorhanden, hält der Schaum dann extremen Belastungen während erstaunlich langer Zeit stand. Würde man den Brandschutzanstrich durch Beschichten bzw. Imprägnieren auftragen, so erhielte man aus dem flexiblen textilen Träger ein Brett, das nur für stationäre Anwendungen geeignet wäre. Die aufgedruckten Klümpchen oder Dämme hingegen verändern den Griff und die Luft- bzw. Wasserdampfdurchlässigkeit des textilen Materials nur wenig. Bei Verwendung eines durchsichtigen flexiblen Trägers, z.B. eines Glasfasergewebes oder auch einer Folie, bleibt trotz der aufgedruckten Punkte des Dämmschutzbildners noch eine beträchtliche Lichtdurchlässigkeit erhalten.The foaming intumescent foam when heated is printed in such a pattern or spacing between the flame retardant centers that the print pattern foams together under the action of heat to form a closed protective layer before the textile carrier suffers considerable damage or loses its strength. Once present, the foam can withstand extreme loads for an astonishingly long time. If you applied the fire protection coating by coating or impregnation, you would get a board from the flexible textile carrier that would only be suitable for stationary applications. The printed lumps or dams, on the other hand, only slightly change the handle and the air or water vapor permeability of the textile material. When using a clear flexible support, e.g. a glass fiber fabric or a film, a considerable amount of light transmission is retained despite the printed points of the insulation protection agent.

Es hat sich gezeigt, daß die erfindungsgemäßen flammwidrig ausgerüsteten flexiblen Materialien den gleichen Schutz bieten, wie bei einer vollflächigen Behandlung, während die Luftdurchlässigkeit noch immer sehr beachtlich und der Griff kaum verändert ist. Auch der Farbton des flexiblen Trägers bleibt auf der unbedruckten Seite erhalten. Die erfindungsgemäß flammwidrig ausgerüsteten flexiblen Materialien erlauben die Verarbeitung zu Schutzbekleidung für extreme Bedingungen im zivilen wie im militärischen Bereich.It has been shown that the flame-retardant flexible materials according to the invention offer the same protection as with a full-surface treatment, while the air permeability is still very remarkable and the grip is hardly changed. The color of the flexible carrier is also retained on the unprinted side. The flexible materials, which are flame-retardant according to the invention, can be processed into protective clothing for extreme conditions in both civil and military fields.
