Abstract

To produce a compound woven fabric of fibers (2) together with polymers, a ribbon of bundled fibers is shrouded by a polymer (4). The plastics ribbon with a fiber core is woven into a fabric, which is bonded and pressed by ironing. The polymers are pref. thermoplastics, delivered by an extruder to the fiber bundles, where the fibers are packed tightly together. The fibers are of polyester or glass, or other fiber materials which are not affected by the plastics extrusion. The shrouding polymer material is polyvinyl chloride (PVC), polyamide, fluorpolymers, and the like. The polymers contain colored pigments. The coated ribbons are covered by a co-extrusion process, to give two or more shrouding layers round the fiber bundles, in different colors. With a PVC shrouding, the outer layer protects the softener in the PVC. Before the fiber bundles are covered with the extruded shrouding, they are immersed in a polymer emulsion to give a bond between the shrouding and fiber bundles. The fibers are heated by the extruder die land (1) to reduce the temp. difference between the fibers and the extruded polymer. The polymer forming the outer layer can contain mineral platelets, to give a varied optical appearance in the ribbons and the woven fabric. The ironing stage gives a closed fiber/polymer bonding.

Bekannt sind Kombinationen von z. B. Polyester/PVC oder Glas/PTFE, die als geschlosse­ ne Gewebe für Zelte und Dachkonstruktionen im Einsatz sind. Diese werden hergestellt in dem zuerst die jeweiligen Gewebe hergestellt werden und diese dann mit Kunststoff-Folien oder Polymer-Pasten zu einer Einheit verdichtet werden. Dies kann ein Laminierverfahren sein oder eine Beschichtung mittels Emulsionen, wobei diese durch Erhitzung mit dem Gewebe verbunden werden.Combinations of z. B. polyester / PVC or glass / PTFE, which as closed ne fabrics for tents and roof structures are used. These are made in first the respective fabrics are made and then these with plastic foils or polymer pastes can be compressed into one unit. This can be a lamination process be or a coating by means of emulsions, these by heating with the Tissues are connected.

ProblemeProblems

Die herkömmlichen Verfahren sind kostspielig und kompliziert. Bei allen Produktionsgän­ gen entstehen Probleme und Ausschuß. Der Webvorgang ist aufwendig, insbesondere wenn Fäden von geringem Durchmesser eingesetzt werden.The conventional processes are expensive and complicated. With all production processes Problems and rejects arise. The weaving process is complex, especially if threads of small diameter are used.

ProblemlösungenProblem solving

Die einfachste und preiswerteste Produktion wäre dann gegeben, wenn die Beschichtung einfacher durchführbar wäre und das Weben schneller vonstatten gehen würde.The simplest and cheapest production would be given if the coating would be easier to carry out and weaving would be faster.

Das Faser-Kunststoff-BandThe fiber-plastic tape

Beim erfindungsgemäßen Verfahren wird dies dadurch erreicht, daß flächige Faserbündel mit dem gewünschten Polymer ummantelt wird und dadurch ein Band entsteht. Dieses Band wird dann verwebt und anschließend in einem Bügelprozeß verdichtet und geschlos­ sen.In the method according to the invention, this is achieved in that flat fiber bundles is encased with the desired polymer and this creates a tape. This The tape is then woven and then compressed and closed in an ironing process sen.

Je nach gewünschter Festigkeit werden eine Anzahl von Fasern parallel verlaufend durch einen Extruder geführt. Diese Fasern werden so mit einem Polymer verbunden, daß eine Streifen entsteht. Depending on the desired strength, a number of fibers run through in parallel led an extruder. These fibers are connected with a polymer so that a Streak arises.  

Die Fasern werden mit dem Streifen komplett umhüllt. Selbst bei schwer zu extrudierenden Polymeren lassen sich solche Streifen gut herstellen, wenn die Fäden entsprechen präpa­ riert werden.The stripes completely cover the fibers. Even with difficult to extrude Such strips can be easily produced by polymers if the threads are in good condition be cured.

Dies geschieht in idealer Weise dadurch, daß die eingesetzten Fasern vor der Extrusion mit einer Emulsion des gleichen Kunststoffs getränkt werden. Nach der Trocknung werden die so vorbereiteten getrocknet und dann vor der Ummantelung auf eine Temperatur er­ hitzt, die ungefähr dem aus der Extruderdüse austretendem Kunststoff entspricht.This is done ideally in that the fibers used prior to extrusion be impregnated with an emulsion of the same plastic. After drying the so prepared dried and then he before the coating to a temperature heats, which corresponds approximately to the plastic emerging from the extruder nozzle.

Hierdurch wird nicht nur der Verbund zum Kunststoff verbessert und sondern auch der im Inneren der Faser befindliche Kunststoff geschmolzen. Hierdurch kann ein Verbund zwi­ schen der Ummantelung und dem im inneren der Faser befindlichen Kunststoff geschehen, wodurch die Haftung optimiert wird.This not only improves the bond to the plastic, but also that in the Melted plastic inside the fiber. As a result, a composite between the sheathing and the plastic inside the fiber, which optimizes liability.

Um eine komplett Ummantelung aller Fasern sicherzustellen, sollten einerseits alle Fasern streng nebeneinander verlaufen und andererseits die Düse des Extruders so konstruiert sein, daß eine komplette Ummantelung sichergestellt ist.In order to ensure a complete sheathing of all fibers, all fibers should on the one hand run strictly next to each other and on the other hand, the extruder nozzle is constructed in this way be that a complete sheathing is ensured.

Die einzelnen Fasern werden nur dann sicher umhüllt, wenn der Kunststoff auch zwischen die Fasern gelangen kann. Auch sollten die Fasern nicht übereinander verlaufen.The individual fibers are only wrapped securely when the plastic is between the fibers can get. The fibers should also not run over one another.

Durch den Einbau von Mineralplättchen können die physikalischen Eigenschaften des Sandes und damit später auch des Endproduktes in gewissen Grenzen verändert werden. Da in dem entstehenden Band diese Plättchen bei der Extrusion gut orientiert werden kön­ nen und dann auf der Bandoberfläche gut zur Wirkung kommen, ist hierdurch sicherge­ stellt, daß die gewünschte Eigenschaft auch erzielt wird.By installing mineral platelets, the physical properties of the Sand and thus later also of the end product can be changed within certain limits. Since these platelets can be well oriented during extrusion in the resulting tape This ensures that it works well on the belt surface represents that the desired property is also achieved.

Durch eine Coextrusion kann auch noch ein Schutzbelag mit aufgetragen werden. Je nach Erfordernis kann das Hauptpolymer anders gefüllt werden, wie der Schutzbelag. So wäre es im Falle von PVC möglich, dieses mit einem Brandschutzpigment zu versehen und dann die Schutzschicht mit Farb- oder/und Reflexionsplättchen. Hierbei sollte die Schutzschicht auch dazu dienen den Austritt des Weichmachers zu verhindern.A protective covering can also be applied by coextrusion. Depending on If necessary, the main polymer can be filled differently from the protective covering. That would be in the case of PVC it is possible to provide it with a fire protection pigment and then the protective layer with color or / and reflection plates. Here, the protective layer also serve to prevent the plasticizer from escaping.

Durch die Extrusion eines Bandes werden große Flächen mit nur einem Extruder erstellt. Bei einem Durchsatz von ca. 20 km/Stunde und einer Bandbreite von 1 cm entstehen so 200 m2 pro Stunde. Dabei können maximal weit über 1 Mio. m2 pro Jahr produziert werden.The extrusion of a tape creates large areas with just one extruder. With a throughput of approx. 20 km / hour and a bandwidth of 1 cm, this creates 200 m 2 per hour. A maximum of well over 1 million m 2 can be produced each year.

Das Band wird in einem weiteren Produktionsschritt verwebt. Wegen der Bandbreite sind sowohl im Kettbereich als auch im Schuß sehr viel weniger Arbeitsschritte notwendig. Bei einem 2 m breiten Material und einem 1 cm Band sind maximal 20 Ketten möglich und pro 1 cm Gewebe ist maximal ein Schuß notwendig. Hierdurch steigt die Produktionskapazität eines normalen Webstuhls um mehr als das Zwanzigfache. Werden üblicher Weise auf einem Webstuhl mit 2 m Webbreite nur 6 m2 pro Stunde gefertigt, steigt dies mit 1 cm- Bändern auf auch etwa 200 m2 pro Stunde. Damit kann auf einem entsprechend für Band­ weben vorgesehenen Webstuhl auch über 1 Mio. m2 pro Jahr hergestellt werden. The belt is woven in a further production step. Because of the bandwidth, much fewer steps are necessary both in the warp area and in the weft. With a 2 m wide material and a 1 cm tape, a maximum of 20 chains are possible and a maximum of one weft is required per 1 cm of fabric. This increases the production capacity of a normal loom by more than 20 times. If only 6 m 2 per hour are usually produced on a loom with a 2 m weaving width, this increases with 1 cm bands to about 200 m 2 per hour. This means that more than 1 million m 2 can be produced per year on a loom that is intended for ribbon weaving.

Auf einem Flachbettkalander, der zumindest für Polymere mit einer Verarbeitungstempe­ ratur von bis zu 240°C sehr geeignet ist, können weit über 200 m2 pro Stunde verdichtet und gebügelt werden.On a flat bed calender, which is very suitable at least for polymers with a processing temperature of up to 240 ° C, well over 200 m 2 can be compressed and ironed per hour.

Da die Bänder bereits mit dem gewünschten Polymer umgeben sind, reicht das Bügeln mit diesem Flachbettkalander aus, um das fertige Produkt eines Gewebe/Polymer-Verbundes zu erzielen.Since the tapes are already surrounded by the desired polymer, ironing is sufficient this flatbed calender to the finished product of a fabric / polymer composite to achieve.

Mit nur drei Maschinen lassen sich daher weit über 1 Mio. m2 pro Jahr dieses Materials fertigen.This means that far more than 1 million m 2 of this material can be produced with just three machines.

Durch die entsprechende Vorbereitung der Faser und die geeignete Ummantelung des Bandes sogar mit mehr als einer Schicht lassen sich die physikalischen Eigenschaften des Endproduktes einrichten. Auch bei der abschließenden Verdichtung durch den Bügelvor­ gang bleibt eine eventuelle Schutzschicht erhalten und wird sogar zur geschlossenen Schutzschicht des gesamten Verbundes. With the appropriate preparation of the fiber and the appropriate coating of the Even with more than one layer, the physical properties of the belt Set up the end product. Even with the final compression by the bow a possible protective layer is preserved and even becomes a closed one Protective layer of the entire network.
