Abstract
Description
Unbrennbares. weiterreißfestes. dimensionsstabiles textiles Flächengebilde Die Brennbarkeit von Ausrüstungsgegenständen aus textilen Erzeugnissen - z.B. Rohre für die Luft- und Gasführung -in Klimaanlagen, Kühlaggregaten, Wetterführung und bei Transportbändern führt besonders in weitläufigen Anlagen wie Untertagebetriebe, Hochhäuser und unter ähnlichen Voraussetzungen immer wieder zu gefährlichen Brandkatastrophen. Hierbei sind diese Ausrüstungsgegenstände nicht nur Ursache des Brandausbruches, weil sie durch unkontrollierbare Hitzeeinwirkung, z.B. Incombustible. tear-resistant. dimensionally stable textile fabric The flammability of equipment made of textile products - e.g. pipes for air and gas routing in air conditioning systems, cooling units, weather management and in the case of conveyor belts, particularly in extensive systems such as underground operations, High-rise buildings and, under similar conditions, again and again to dangerous fire disasters. These pieces of equipment are not only the cause of the outbreak of fire, because they are caused by uncontrollable exposure to heat, e.g.
durch Reibung von Antriebs- oder Steuerelementen, oder durch elektrische Kurzschlüsse entzündet werden. Sie führen vielmehr diese örtlich entstandenen Brände weiter und werden hierdurch zu Feuerbrücken.by friction of drive or control elements, or by electrical Short circuits are ignited. Rather, they lead these local fires further and thereby become fire bridges.
Man ist bemüht, diese Gefahr durch die Einführung schwerentflammbarer Textilerzeugnisse" einzudämmen. Diese Schwerentflammbarkeit erreicht man durch eine Beschichtung an sich brennbarer Textilien mit einer Beschichtung, die durch geeignete Zusätze von Chemikalien schwerentflammbar bzw. feuerhemmend abdeckt. Die Erfahrung zeigt aber, daß trotz dieser durch eine sehr strenge Normprüfung abgesicherte Methode immer wieder Brandkatastrophen auftreten.Efforts are being made to reduce this risk by introducing flame-retardant Textile products "to contain. This flame retardancy is achieved by a Coating of combustible textiles with a coating that is suitable Additions of chemicals are flame retardant or fire retardant. The experience but shows that despite this method, which is secured by a very strict standard test fire disasters occur again and again.
Eine absolute Sicherheit wird erst erreicht, wenn an die Stelle der "Schwerentflammbarkeit"auch bei textilen Erzeugnissen die "Unbrennbarkeit" tritt. Eine derartige Unbrennbarkeit kann nicht nur durch die Beschichtung erreicht werden, sie muß sich vielmehr auch auf das eigentliche Trägermaterial erstrecken. Nur hierdurch wird gewährleistet, daß selbst bei Verletzungen oder Verschleiß der Beschichtung die Brandgefahr nicht eintreten kann.Absolute security is only achieved when the "Flame retardancy" also applies to textile products and "incombustibility". Such incombustibility can not only be achieved through the coating, rather, it must also extend to the actual carrier material. Only through this ensures that even if the coating is damaged or worn the risk of fire cannot occur.
Ein unbrennbares Trägermaterial war bisher nur durch die Verwendung von anorganischen Fasern wie Glas, Asbest, Kohle, Keramik herzustellen. Da aber die bisher übliche Beschichtung nur schwerentflammbar aber nicht unbrennbar war, bildet auch dieses Trägermaterial keine Sicherheit für die Verhttung von Bränden und deren Weiterleitung. Außerdem machen Garne aus derartigen anorganischen Fasern technische Schwierigkeiten, weil sie besonders in Bezug auf Geschmeidigkeit und Sprödigkeit keine echten textilen Eigenschaften haben. Derartige Fasern splittern bei mechanischen Beanspruchungen sehr leicht und sind daher nur begrenzt einsetzbar.An incombustible carrier material was previously only through use of inorganic fibers such as glass, asbestos, carbon, ceramics. Here but the previously common coating was only flame retardant but not non-combustible, Even this carrier material does not provide any security for preventing fires and their Forwarding. In addition, yarns make such inorganic ones Fibers technical difficulties because they are particularly flexible in terms of suppleness and brittleness have no real textile properties. Such fibers splinter very light under mechanical stress and can therefore only be used to a limited extent.
Über die schwerentflammbare Beschichtung wurde schon gesagt, daß diese Eigenschaft durch geeignete Zusätze von Chemikalien zu der an sich sehr leicht brennbaren Polyvinylchlorid-Beschichtung zu erreichen ist. Für ein unbrennbares textiles Flächengebilde müßte auch für die Beschichtung ein Produkt verwendet werden, das absolut unbrennbar ist.It has already been said about the flame-retardant coating that this Property due to suitable additions of chemicals to the very easily combustible one Polyvinyl chloride coating can be achieved. For an incombustible textile fabric a product that is absolutely non-flammable would also have to be used for the coating is.
Eine weitere Gefahr bei der Verwendung textiler Ausrüstungsgegenstände liegt in der geringen Dimensionsstabilität und der relativ geringen Reißfestigkeit, insbesondere auch der Weiterreißfestigkeit. Man versucht im allgemeinen, diese Mängel durch webtechnische Maßnahmen, wie hohen Garneinsatz, Bindungsverstärkungen und durch nachträgliche Versteifung mittels Beschichtung auszugleichen. Hierdurch entstehen verhältnismäßig schwere und aufwendige Produkte, ohne daß ein optimaler Erfolg erzielt werden könnte. Besonders bei der Wetterführung unter Tage und bei Transportbändern würde aber eine verbesserte Dimensionsstabilität und Weiterreißfestigkeit die Sicherheit für die vor Ort arbeitenden Menschen beträchtlich erhöhen. Diese verbesserten Eigenschaften würden Beschädigungen durch die immer mehr zum Einsatz kommenden mechanischen Vorrichtungen und die hierdurch erreichten erhöhten Produktionsmengen weitgehend vermeiden.Another danger when using textile equipment lies in the low dimensional stability and the relatively low tear resistance, especially the tear strength. One generally tries to address these shortcomings through technical weaving measures, such as high use of yarn, reinforcement of the weave and compensated for by subsequent stiffening by means of a coating. This creates relatively heavy and expensive products without achieving optimal success could be. Especially when it comes to underground weather management and conveyor belts however, improved dimensional stability and tear strength would improve safety for the people working on site. These improved properties damage would be caused by the increasing use of mechanical devices and largely avoid the increased production volumes achieved as a result.
Aufgabe der Erfindung ist es, ein textiles Flächengebilde vorzuschlagen, dessen Trägermaterial weiterreißfest, dimensionsstabil und unbrennbar ist und von einer Beschichtung abgedeckt wird, die nicht nur schwerentflammbar, sondern absolut unbrennbar ist und dadurch weder die Entstehung örtlicher Brände noch die Weiterleitung von Bränden zuläßt.The object of the invention is to propose a textile fabric, whose carrier material is tear-resistant, dimensionally stable and non-flammable and of a coating is covered, which is not only flame-retardant, but absolutely is incombustible and therefore neither the development of local fires nor the transmission of fires.
Erfindungsgemäß wird die Unbrennbarkeit durch folgende Kombination erreicht: Für das Trägergewebe (Fig. a/l) werden Garne aus aromatischen Polyamiden, den sog. Aramiden, verwendet.According to the invention, the incombustibility is achieved by the following combination achieved: For the carrier fabric (Fig. A / l) yarns are made of aromatic Polyamides, the so-called aramids, are used.
Unter Aramiden versteht man Polyamide, die im Gegensatz zu den bekannten gradkettigen Polyamiden Nylon und Perlon aus ringförmig aromatischen Komponenten aufgebaut sind. Besonders geeignet sind z.B. m-Phenylendiamin oder p-Phenylendiamin.Aramids are polyamides, which in contrast to the well-known straight-chain polyamides nylon and perlon from ring-shaped aromatic components are constructed. For example, m-phenylenediamine or p-phenylenediamine are particularly suitable.
An die Stelle der Aramide können auch Fäden aus fluoriertem Kohlenwasserstofi, dem Polytetrafluoräthylen, bekannt unter dem Namen "Teilon" eingesetzt werden.Instead of the aramids, threads made of fluorinated hydrocarbons, the polytetrafluoroethylene, known under the name "Teilon" are used.
Für die Beschichtung (Fig. a/2) werden ebenfalls fluorierte Kohlenwasserstofie verwendet.Fluorinated hydrocarbons are also used for the coating (Fig. A / 2) used.
Unter fluorierten Kohlenwasserstoffen versteht man z.B. Polymere, Elastomere und Plastomere aus Tetrailuoräthylen, aus Copyolymerisaten, aus Tetrailuoräthylen und Hexailuoräthylen, Polymerisate aus Epoxyiluoräthylen sowie Polyvinyliluorid und Polyvinyldifluorid.Fluorinated hydrocarbons are understood to mean, for example, polymers, Elastomers and plastomers made from tetrafluoroethylene, from copolymers, from tetrafluoroethylene and Hexailuoräthylen, polymers from Epoxyiluoräthylen as well as polyvinyliluorid and polyvinyl difluoride.
Aus der Verbindung dieser beiden Komponenten, dem Trägergewebe (1) aus Aramiden oder Polytetrafluoräthylen und der Beschichtung oder Kaschierung (2) mit Folien-aus fluorierten Kohlenwasserstoffen, entsteht ein Flächengebilde, das absolut unbrennbar ist. Es hat außerdem noch den Vorteil einer hohen Festigkeit bei geringem Gewicht, denn z.B. die Aramide haben nur ein speziiisches Gewicht von 1.4 - 1.5 (Stahl 7.86, Glas 2.58) bei einer Festigkeit, die Stahl um das Siache und Polyester und Polyamide um etwa das 4fach übertrifft.From the combination of these two components, the carrier fabric (1) made of aramids or polytetrafluoroethylene and the coating or lamination (2) With foils made of fluorinated hydrocarbons, a flat structure is created that is absolutely non-flammable. It also has the advantage of high strength with low weight, because e.g. the aramids only have a specific weight of 1.4 - 1.5 (steel 7.86, glass 2.58) with a strength that steel around the Siache and polyester and polyamides by about 4 times.
Die Eigenschaiten der vorgenannten Beschichtung können durch den Zusatz von Binde- und Füllmitteln zu der Einbettungsmasse in bekannter Weise beeinflußt werden. Vor allem im Bereich der Wärmeleitiähigkeit, der elektrischen Leitiähigkeit zur Verhütung statischer Auiladungen, der Korrosionsiestigkeit und der UV-Beständigkeit sind durch Zusatz von metallischen Pulvern, Ruß, Silikaten, Glas die gewünschten Eigenschaiten zu erreichen, ohne die Unbrennbarkeit zu beeinilussen.The properties of the aforementioned coating can be achieved by adding influenced by binders and fillers to the embedding compound in a known manner will. Especially in the area of thermal conductivity, electrical conductivity for the prevention of static charges, the resistance to corrosion and the UV resistance are the desired ones by adding metallic powders, carbon black, silicates and glass To achieve properties without affecting the incombustibility.
Die Dimensionsstabilität des textilen Flächengebildes und seine Reißiestigkeit werden durch die hohe Festigkeit und geringe Dehnung der vorgeschlagenen Faserstoffe sehr günstig beeinilußt.The dimensional stability of the textile fabric and its tear resistance are due to the high strength and low elongation of the proposed fiber materials very favorably influenced.
Die Weiterreißfestigkeit kann durch bekannte webtechnische Maßnahmen, wie Garnverdopplung in bestimmten Abständen in Kette und/oder Schuß etc., die nicht Gegenstand der Erfindung sind, erhöht werden. Sofern diese Maßnahmen für den Einsatzzweck des Flächengebildes nicht ausreichen, wird erfindungsgemäß vorgeschlagen, mindestens 4 flächige Fadenlagen diagonal kreuzend in einer Gewebebahn fest miteinander zu verbinden.The tear strength can be achieved by known weaving measures, such as yarn doubling at certain intervals in warp and / or weft etc. that are not The subject of the invention are to be increased. Provided these measures for the purpose of the planar structure are not sufficient, it is proposed according to the invention, at least 4 flat layers of thread, crossing diagonally, tightly together in a web of fabric associate.
Die Fig. b, c und d zeigen die Anordnung der sich kreuzenden Fadenlagen (a', b', c', d') und der sich daraus ergebenden Effekte für die Erhöhung der Stabilität und Weiterreißfestigkeit. Die Herstellung derartiger Flächengebilde kann nach den bekannten Veriahren des Webens, Nähens, Nadelns, Flechtens, Legens und Kaschierens erfolgen. Besonders rationell ist das Verfahren des Kaschierens von mindestens zwei rechtwinklig gewebten, ilächigen Textilgebilden, die vor dem Kaschieren entsprechend der gewünschten Verkreuzung zugeschnitten werden.Figs. B, c and d show the arrangement of the intersecting layers of threads (a ', b', c ', d') and the resulting effects for increasing the stability and tear strength. The production of such flat structures can according to the known methods of weaving, sewing, needling, braiding, laying and lamination take place. The method of lamination of at least two is particularly efficient Right-angled woven, flat textile structures, which are made accordingly before lamination cut to the desired intersection.
Die sich quadronal stabilisierenden Flächengebilde müssen nicht unmittelbar aufeinander gebracht werden. Es können vielmehr flächige Medien, wie Folien, Vliese, Gewirke, Geflechte als Zwischenlage eingebracht werden. Hierdurch können dem Fertigprodukt besondere Eigenschaiten bezüglich Undurchlässigkeit , Schmiegsamkeit, Weichheit -um nur einige zu nennen - vermittelt werden. Besonders das Einbringen von Folien zur Erzielung einer absoluten Undurchlässigkeit ist erfindungsgemäß von Bedeutung.The quadronally stabilizing flat structures do not have to be immediate be brought to one another. Rather, flat media such as foils, fleeces, Knitted fabrics, braids are introduced as an intermediate layer. This allows the finished product special properties regarding impermeability, pliability, softness to name just a few. Especially the introduction of foils to achieve absolute impermeability is important according to the invention.
Derartige Produkte zeigen nicht nur eine höhere Dimensionsstabilität und Zugfestigkeit, sie erhalten auch eine wesentlich erhöhte Weiterreißfestigkeit0 Hierdurch wird die den textilen Flächengebilden von Hause aus anhaitende hohe Empfindlichkeit gegen mechanische Einflüsse wie Schlag und Stoß wesentlich gemildert und die Abgrenzung örtlicher Verletzungen zuverlässig erreicht.Such products not only show a higher dimensional stability and tensile strength, they also have a significantly increased tear resistance0 This increases the inherent high sensitivity of the textile fabrics Against mechanical influences such as impact and shock, and the demarcation is significantly softened local injuries reliably achieved.
