■ ästhetische Wirkungen zeigt.■ shows aesthetic effects.

Unter dem Begriff "Mikrofascrn" werden dabei Fasern verstanden, die einen Titer im Bereich von 0,01 denier bis 0,40 denier, vorzugsweise in der Größenordnung von 0,08 bis 0,15 denier haben.The term "microfibers" refers to fibers that have a titer in the range of 0.01 denier to 0.40 denier, preferably in the range of 0.08 to 0.15 denier.

Das Mikrofaservliesmaterial aus Mikrofasern aus Polyäthylenterephthtalat in Polyurethan kann nach einem Verfahren erhalten werden, das im wesentlichen die folgenden Schritte umfaßt:The microfiber nonwoven material made of polyethylene terephthalate microfibers in polyurethane can be obtained by a process which essentially comprises the following steps:

Ein Vliesstoff aus Polyäthylenterephthalat-Mikrofasern wird mit einem Polyurethanelastomermaterial imprägniert,A nonwoven fabric made of polyethylene terephthalate microfibers is impregnated with a polyurethane elastomer material,

das Polyurethanelastomermaterial wird koaguliert, um ein Mikrofaserverbundbahnmaterial zu bilden,the polyurethane elastomer material is coagulated to form a microfiber composite sheet material,

das Mikrofaserverbundbahnmaterial wird geschliffen, um einen Mikrofaserrohrvliesstoff zu bilden, undthe microfiber composite web material is ground to form a microfiber tubular nonwoven fabric, and

rier Mikroffisnrrohrvliesstof f v/ird gefärbt, um ein gefärbtes Endprodukt zu erzeugen.Each microfiber nonwoven fabric is dyed to produce a colored final product.

Der Vliesstoff aus Polyäthylenterephthalat-Mikrofasern kann seinerseits aus einem Rohfilz ?us Stapelfasern erhalten werden, der aus Polyäthylentereph jiat-Mikrofasern berteht, die in eir.e Polystyrolmatrix eingebettet sind, indem der Rohfilz genadej-C wird, um einen Nadelfilz zu erzeugen, und der Nadelfilz zunächst mit einer wäßrigen Polyvinylalkohollösung und dann mit Perchloräthylen behandelt wird, um aie Polystyrolmatrix aufzulösen und den Vliesstoff aus Polyäthylenterephthalat-Mikrofasern zu gewinnen.The nonwoven fabric of polyethylene terephthalate microfibers can in turn be obtained from a raw staple fiber felt consisting of polyethylene terephthalate microfibers embedded in a polystyrene matrix, by straightening the raw felt to produce a needle-punched felt and treating the needle-punched felt first with an aqueous polyvinyl alcohol solution and then with perchloroethylene to dissolve the polystyrene matrix and obtain the nonwoven fabric of polyethylene terephthalate microfibers.

Das in dieser Weise erhaltene Mikrofaservliesmaterial sieht ausgezeichnet aus, ist gut handhabbar, hat ein geringes Gewicht, gute Veloureigenschaften und ist gegenüber Licht und Stickstoffoxiden in der Luft beständig.The microfiber fleece material obtained in this way looks excellent, is easy to handle, has a low weight, good velour properties and is resistant to light and nitrogen oxides in the air.

Gemäß der Erfindung wird ein derartiges Mikrofaservliesmaterial oder ein ähnliches Mikrofaservliesmaterial, das gegebenenfalls perforiert ist, mit einem textlien Material verbunden, um ein neues Produkt zu erhalten, das die weitvollen ästhetischen Eigenschaften mit guten mechanischen Eigenschaften kombiniert, so daß es sich zur Verwendung auf dem Gebiet der Innendekoration um' niii (U-rn Transp^rtgebi et e i gnet .According to the invention, such a microfiber nonwoven material or a similar microfiber nonwoven material, optionally perforated, is combined with a textile material to obtain a new product that combines wide aesthetic properties with good mechanical properties, so that it is suitable for use in the field of interior decoration and transport.

Die textlien Materialien, die für diesen Zweck verwandt werden, sind Wirkwaren oder textile Materialien oder Gewebe verschiedener Art, wie beispielsweise Baumwoll e - ,Polyest er-, Nylonviskosematerialien oder ähnliche Materialien, odor Mischgewebe mit Zusammensetzungen, die in Abhängigkeit von den gewünschten Endeigenschaften gewählt sind. Diese textlien Materialien können unbehandelt oder gefä:bt oder bedruckt sein. Die bedruckten oder gefärbten textlien Materialien, die verschiedene dekorative Muster tragen können, ergeben in Verbindung mit dem Mikrofaservliesmaterial ein Endprodukt, das vom ästhetischen Standpunkt aus besonders angenehm ist. Einer oder beide Bestandteile des Verbundkörpers können weiterhin flammen- oder feuerfest sein.The textile materials used for this purpose are knitted or woven textile materials or fabrics of various types, such as cotton, polyester, nylon viscose or similar materials, or blended fabrics with compositions chosen depending on the desired final properties. These textile materials can be untreated or dyed or printed. The printed or dyed textile materials, which can bear various decorative patterns, in combination with the microfiber nonwoven material, give a final product that is particularly pleasing from an aesthetic point of view. One or both components of the composite body can also be flame or fire resistant.

Der erfindungsgemäße Verbundkörper eignet sich zur Verwendung auf dem Gebiet der Innendekoration und auf dem Gebiet des Transportes und kann dazu verwandt werden, Sofas, Bürosessel, Sitze von Fahrzeugen usw. zu überziehen.The composite body according to the invention is suitable for use in the field of interior decoration and in the field of transportation and can be used to cover sofas, office chairs, vehicle seats, etc.

Bei einem nicht perforierten Mikrofaservliesmaterial kann die Verbindung mit dem textlien Material vorzugsweise mittels des folgenden Mehrpunktverfahrens erfolgen.In the case of a non-perforated microfiber fleece material, the connection to the textile material can preferably be made using the following multi-point process.

Das textile Material in Form von vorher gebildeten Rollen wird über eine Abwickeleinheit einer Caratschmaschine zugeführt, die aus einer geprägten und geheizten Rolle besteht,The textile material in the form of previously formed rolls is fed via an unwinding unit to a caratsch machine, which consists of an embossed and heated roll,

in deren inneren I'',hlraum das Bindemittel pulver nus Polyamid oder Polyester einzugeben wird. Durch eine kontrollierte Erwärmung bringt die Rolle über einen Kontakt Punkte des Rindemittels t-ii das textile Material. Das in dieser Weise erhaltene textile Material mit den aufgebrachten Punkten des Bindemittels wird durch einen Infrarotofen geleiter, in r\em die tunkte des Bindematerials zum Schmelzen gebracht werden, woraufhin das textile Material mit den Punkten des geschmolzenen Bindemittels mit dem Mikrofaservliesmaterial an einem Kalander mit gummibeschichteten Rollen und unter einem gesteuerten Druck verbunden wird.into whose inner cavity the binding agent powder of polyamide or polyester is introduced. Through controlled heating, the roller brings the contact points of the binding agent onto the textile material. The textile material obtained in this way with the applied points of the binding agent is passed through an infrared oven in which the dots of the binding material are melted, whereupon the textile material with the points of the melted binding agent is bonded to the microfiber fleece material on a calender with rubber-coated rollers and under a controlled pressure.

Wenn ein peri< riertes Mikrofaservliesmaterial verwandt wird, dann wird das bindemittel auf dieses Material und nicht auf das textile Material aufgebracht. Ein derartiges perforiertes Material wird insbesondere auf einem in Form eines Netzförderers ausgebildeten Förderband zu einem siebartigen Verteiler befördert, der es ermöglicht, das Bindemittelpulver gleichmäßig zu verteilen, wahrend ein Teil des Pulvers, das in das Innere der Öffnung der Löcher fällt, durch das Netz hindurchgeht, das das Förderband bildet, und im darunter liegenden Bereich gesammelt wird. Das Mikrofaservliesmaterial , das auf dem Förderband bleibt, wird dann zu einem Ofen mit sorgfältig gesteuerter Temperatur befördert, um das Bindemittel zu schmelzen. Die Verbindung des textlien Materials erfolgt mittels eines Kalanders an dem Mikrofaservliesmaterial, sobald dieses den Ofen verläßt.When a perforated microfiber nonwoven material is used, the binder is applied to this material and not to the textile material. Such a perforated material is conveyed in particular on a conveyor belt in the form of a mesh conveyor to a sieve-like distributor which allows the binder powder to be evenly distributed, while part of the powder which falls inside the opening of the holes passes through the mesh forming the conveyor belt and is collected in the area below. The microfiber nonwoven material which remains on the conveyor belt is then conveyed to an oven at a carefully controlled temperature in order to melt the binder. The textile material is bonded to the microfiber nonwoven material by means of a calender as soon as it leaves the oven.

Das Mikrofaservliesmaterial kann fortlaufend über Pressen perforiert sein, die mit Stanzeinrichtungen versehen sind, die an einer Platte angebracht sind. Die Späne können mittels eines Luftstromes ausgeblasen werden.The microfiber fleece material can be continuously perforated using presses equipped with punching devices attached to a plate. The chips can be blown out using an air stream.

Die vorliegende Erfindung wird weiterhin anhand von Versuchsbeispielen beschrieben.The present invention is further described using experimental examples.
