Abstract

Matted fibre reinforcing webs used in the mfr. of shoe toe caps, clothing, furnishing, upholstering and decorating industry and formed of polyamide, PVC, or polypropylene fibres have their outer fibre layer or layers compacted and melted using heated pressure rollers. In the case of compacting one layer only, the other roller is not heated.

Description

Neue Versteifungsmaterialien Gegenstand der vorliegenden Erfindung sind neue-Versteifungsmaterialien aus thermoplastischen Kunststoffen, insbesondere thermoplastischen Gewebe-, Filz-, Vliesbahnen oder Gewirren sowie ein Verfahren zu ihrer Herstellung Die Verwendung von Polystyrol und anderen thermoplastischen Materialien als versteifende Mittel bei der Herstellung von Schuhkappenstoff u.a. ist nicht mehr neu. So wird beispielsweise in der as 1 485 699 ein Polystyrol-Schuhkappenstoff beschrieben, bei dessen Herstellung zunächst ein gerauhtes Gewebe mit einer Polystyrol-Dispersion getränkt und anschließend durch Nachbehandlung zwischen 16000 heißen Walzen verfestigt wird.Durch die Nachbehandlung verschmilzt die vorher pulverig weiße Imprägnierung zu einer glasig transparenten Masse, in welche das Gewebe als Verstärkungsmittel eingebettet ist.New stiffening materials are the subject of the present invention are new-stiffening materials made from thermoplastics, in particular thermoplastic woven, felt, non-woven webs or tangles and a process for their manufacture The use of polystyrene and other thermoplastic Materials used as stiffening agents in the manufacture of shoe cap fabric, etc. is not new anymore. For example, as 1 485 699 describes a polystyrene shoe cap material described, in its production initially a roughened fabric with a polystyrene dispersion soaked and then solidified by post-treatment between 16,000 hot rollers The after-treatment melts the previously powdery white impregnation to a glassy, transparent mass, in which the fabric acts as a reinforcing agent is embedded.

Derart hergestellte Steifkappenstoffe weisen zwar eine schnelle Anlösbarkeit sowie eine gute Klebkraft der durch Lösungsmittel erweichten Kappen auf, müssen jedoch bei Verwendung in ungefütterten Schuhen zusätzlich auf einer Seite mit einem, das Futter ersetzenden beflockten Gewebe oder einer Papierbahn kaschiert werden. Außerdem sind sie häufig hinsichtlich Dicke und Gleichförmigkeit der thermoplastischen Schicht nicht zufriedenstellend.Rigid canopy materials produced in this way are admittedly quick to dissolve as well as good adhesive strength of the caps softened by solvents however, when used in unlined shoes, additionally on one side with a, flocked fabric or a paper web to replace the lining. In addition, they are often thermoplastic in terms of thickness and uniformity Layer unsatisfactory.

Aus der OS 1 485 824 ist weiterhin ein Versteifungsmaterial bekannt, das dadurch# gekennzeichnet ist, daß es zwei Lagen aus thermoplastischem Polymerisatmaterial enthält, die durch ein biegsames, weitmaschiges, zwischen den beiden Lagen eingefügtes Band, z.B. ein Band aus grober Leinwand, miteinander verschmolzen sind. Durch den Schmelzvorgang wird das Gewebe ebenfalls in Thermoplaste eingebettet, jedoch können auch durch die abgewandelte Verfahrenstechnik die vorerwähnten Nachteile nicht behoben werden. Darüberhinaus ist das Herstellungsverfahren aufwendig und zur Erzeugung billiger Kappenstoffe nicht geeignet.A stiffening material is also known from OS 1 485 824, which is characterized in that it has two layers of thermoplastic polymer material contains, which is inserted by a flexible, wide-meshed, between the two layers Tape, e.g. a tape made of coarse canvas, are fused together. Through the During the melting process, the tissue is also embedded in thermoplastics, but can even the modified process technology did not remedy the aforementioned disadvantages will. In addition, the manufacturing process is complex and costly to produce cheaper cap fabrics are not suitable.

Es stellte sich somit die Aufgabe, verbesserte Versteifungsmaterialien zu finden, die die angegebenen Nachteile nicht aufweisen und nach einem einfacheren Verfahren preisgünstiger hergestellt werden können.The task was thus to provide improved stiffening materials to find that do not have the specified disadvantages and for a simpler one Process can be produced more cheaply.

Die Versteifungsmaterialien gemäß der Erfindung sind dadurch gekennzeichnet, daß sie aus einem thermoplastischen, schmelzbaren Fasermaterial bestehen, das durch Einwirkung von Druck und Wärme ein- oder beideseitig verschmolzen ist. Sie können überraschenderweise in sehr einfacher Weise dadurch hergestellt werden, daß ein thermoplastisches, schmelzbares Fasermaterial, insbesondere eine Gewebe-, Filz-, Vliesbahn oder Gewirr, durch zwei oder mehrere beheizte, paarweise angeordnete Druckrollen geführt und dabei soweit erhitzt wird, daß auf mindestens einer der beiden Oberflächen die Fasern zu einer zusammenhängenden Schicht verschmolzen werden.The stiffening materials according to the invention are characterized by that they consist of a thermoplastic, fusible fiber material that by The effect of pressure and heat is fused on one or both sides. You can Surprisingly, can be produced in a very simple manner that a thermoplastic, fusible fiber material, in particular a fabric, felt, Fleece web or tangle, by means of two or more heated pressure rollers arranged in pairs out and heated so far that on at least one of the two surfaces the fibers are fused into a cohesive layer.

Durch Zusatz nicht schmelzbarer Stoffe, z.B. Baumwollfasern, kann weiterhin der Verschmelzungsprozess so geleitet werden, das#gasdurchlässige Schichten entstehen. Die durch Schmelzen des thermoplastischen Fasermaterials hergestellten Schichten können aber auch in Abhängigkeit von der Temperatur, Druck und Zeit ohne Zusatz nicht schmelzbarer Stoffe in luftdurchlässiger Form gebildet werden.By adding non-meltable materials, e.g. cotton fibers, The fusion process continues to be conducted so that the # gas-permeable layers develop. Those made by melting the thermoplastic fiber material Layers can also be without, depending on the temperature, pressure and time Addition of non-meltable substances are formed in air-permeable form.

Je nach Verwendungszweck können die neuen Versteifungsmaterialien weiterhin hinsichtlich ihrer Eigenschaften und ihres Aussehens in mannigfaltiger Weise variiert werden.Depending on the intended use, the new stiffening materials continue to be varied in terms of their properties and their appearance Way can be varied.

Das thermoplastische Fasermaterial kann aus allen bekannten schmelzbaren und damit auch in Faserform erhältlichen Kunststoffen bestehen. So können beispielsweise Gewebe, Vliese und Gewirre aus Polyolefinen, insbesondere Polypropylen, aus Polyestern, beispielsweise Polyacrylestern, Polymethacrylestern und Polgvinylacetat sowie deren substituierten Produktenlaus Polyvinylchlorid, das gegebenenfalls auch nachchloriert sein kann, Polyvinylidenchlorid, aus Polystyrol und Polyamiden eingesetzt werden.The thermoplastic fiber material can be made of any known fusible material and thus also made of plastics available in fiber form. For example Fabrics, fleeces and tangles made from polyolefins, especially polypropylene, made from polyesters, for example polyacrylic esters, polymethacrylic esters and polyvinyl acetate and their substituted products of polyvinyl chloride, which may also be post-chlorinated can be, polyvinylidene chloride, polystyrene and polyamides can be used.

Selbstverständlich können auch Gemische oder Mischpolymerisate der angeführten Kunststoffe verwendet werden. Auch kann das synthetische thermoplastische Fasermaterial in Mischung mit natürlichen Fasern verwendet werden, etwa mit Fasern aus Baumwolle,Zellulose, Jute, Wolle u.a. Auf jeden Fall wird man bei der Auswahl des Fasermaterials - um optimale Werte zu erzielen- jeweils auf den vorgesehenen Verwendungszweck abstellen, also z.B. darauf, ob das Fasermaterial einseitig oder beidseitig verschmolzen werden soll, ob das Dickenverhältnis der geschmolzenen Schicht (en) zu der ungeschmolzenen Faserschicht größer oder kleiner als 1 sein soll u.a.Of course, mixtures or copolymers can also be used listed plastics are used. Also can be the synthetic thermoplastic Fiber material can be used in a mixture with natural fibers, for example with fibers made of cotton, cellulose, jute, wool, etc. of the fiber material - in order to achieve optimal values - in each case on the intended Stop the intended purpose, So e.g. whether the fiber material to be fused on one or both sides, whether the thickness ratio of the melted layer (s) to the unmelted fiber layer larger or smaller should be as 1 i.a.

Die neuen Versteifungsmaterialien können auf vielen Gebieten verwendet werden. Es sollen daher auch nur einige Anwendungsgebiete beispielhaft aufgezählt werden: als Kappenstoff oder Versteifungsmaterial in Schuhteilen, und zwar sowohl in gefütterten als auch ungefütterten Schuhen, als synthetisches Leder in der Täschnerwarenindustrie, als Verkleidungsmaterial in der Möbel- oder Autoindustrie, als Versteifung s oder Dekorationsmaterial in der Textilindustrie, als Lampenschirmmaterial in der Gebrauchsgüterindustrie, als Auslageware für Teppichböden, als Futter und Oberstoff für Hausschuhe und v.a.The new stiffening materials can be used in many fields will. Therefore, only a few areas of application should be listed by way of example be: as cap material or stiffening material in shoe parts, both in lined and unlined shoes, as synthetic leather in the bag-making industry, as cladding material in the furniture or car industry, as reinforcement s or Decoration material in the textile industry, as lampshade material in the consumer goods industry, as display goods for carpets, as lining and outer fabric for slippers and above all

Wie bereits erwähnt worden ist, werden die neuen Versteifungsmaterialien durch ein- oder beidseitiges Verschmelzen eines Faservlieses unter Druck hergestellt. Druck, Temperatur und Zeitdauer werden hierbei in Abhängigkeit von Art und Zusammensetzung des Fasermaterials sowie der gewünschten Dicke und den geforderten Eigenschaften der verschmolzenen Schicht gewählt. Allgemein gültige Richtlinien und Regeln für die Herstellung der neuen Versteifungsmaterialien können daher nicht aufgestellt werden, sondern müssen aus den an sich bekannten Eigenschaften der thermoplastischen Materialien abgeleitet oder durch Vorversuche ermittelt werden.As has already been mentioned, the new stiffening materials produced by fusing a fiber fleece on one or both sides under pressure. Pressure, temperature and duration depend on the type and composition the fiber material as well as the desired thickness and the required properties of the fused layer. Generally applicable guidelines and rules for the production of the new stiffening materials can therefore not be established but must be based on the properties of the thermoplastic, which are known per se Materials derived or determined through preliminary tests.

rauch einer weiteren Ausführungsforin der Erfindung kann der Schmelzvorgang auch auf Prägewalzen durchgeführt werden, sodaß Materialien mit einer dekorativen Oberfläche gebildet werden, die mit Vorteil als Wandverkleidungsmaterial und insbesondere in der Täschnerindustrie eingesetzt werden.The melting process can also be used in a further embodiment of the invention can also be carried out on embossing rollers, so that materials with a decorative Surface are formed with advantage as a wall cladding material and in particular are used in the bag-making industry.

Dabei können selbstverständlich auch homogen oder verschieden eingefärbte Fasermaterialien eingesetzt werden, so daß zusätzliche dekorative Effekte entstehen.It goes without saying that they can also be colored homogeneously or differently Fiber materials are used, so that additional decorative effects are created.

Anhand des nachfolgenden Beispiels und der beiliegenden Figuren soll nun das erfindungsgeinäße Verfahren noch näher erläutert werden, Ausführungsbeispiel Ein etwa 1 mm dickes, isotaktisches Polypropylen - Vlies, bestehend aus 30 Gew.% Polypropylen - Faser DL ( 17 dtex/60 mm: und 70 Gew.% Polypropylen - Faser S ( 17 dtex/60 mm) wird mit einer Geschwindigkeit von 2 m/mLn. durch ein beheiztes Walzenpaar geführt und beidseitig an der Oberfläche verschmolzen. Das Flächengewicht des Polypropylen - Vlieses betrug 350 gZm2 und die Temperatur der beiden Walzen 18000.Based on the following example and the accompanying figures the method according to the invention will now be explained in more detail, exemplary embodiment An approximately 1 mm thick, isotactic polypropylene fleece, consisting of 30% by weight Polypropylene - fiber DL (17 dtex / 60 mm: and 70% by weight of polypropylene - fiber S (17 dtex / 60 mm) is carried out at a speed of 2 m / mLn. by a heated pair of rollers guided and fused on both sides on the surface. The basis weight of the polypropylene - Fleece was 350 gZm2 and the temperature of the two rollers was 18,000.

Die Herstellung des hierbei gebildeten, beidseitig versteiften Materials ist in Fig. 1 schematisch wiedergegeben, in der die beheizten Walzen mit der Bezugsziffer 1, das Polypropylen-Vlies mit 2 und die verschmolzenen Schichten des flieses-init 3 bezeichnet sind.The manufacture of the material that is stiffened on both sides is shown schematically in Fig. 1, in which the heated rollers with the reference number 1, the polypropylene fleece with 2 and the fused layers of the fleece-init 3 are designated.
