Abstract

A process for coating woven or knitted plastic textile fabric with polymer (especially PVC paste) in which the coating polymer is predried to a gel-like, brittle state, applied with a laminating pressure such that it adheres to the fibres even when the fabric is stretched on the stretcher frame, and then converted into the elastic state in the drying or gelling channel. A process for the production of polymer-coated (especially PVC-coated) woven or knitted plastic fabric (especially textile-like fabrics) in which the coating is applied by known reversal processes (or directly) in amounts of 80-300 g/m<2> so that, due to the lamination pressure, the polymer adheres exceptionally well to the fibres even when the fabric is stretched. The coating polymer used is predried to a gel-like, brittle state. After removing the release paper or fabric, the coated product is placed on a stretcher frame, stretched in one or both directions in the still-cold feeding section and then brought to an elastic state in the drying or gelling channel (gelled or optionally foamed in the case of PVC). If foamable PVC paste is used, air permeability is controlled by the amount of paste applied and the degree of foaming (depending on the type of textile substrate).

Description

Es ist bekannt, dass man offene Gewebe mit PVC-Plastisolen tränkt, abquetscht oder abrakelt und dann geliert oder auch schäumt. Solche Artikel werden zu vielerlei Verwendung wie Teppichunterlagen, Tischdecken und ähnlichem benutzt. Alle bekannten und so hergestellten Artikel sind beidseitig mit PVC umgeben und werden in sehr offener Struktur geliefert. Sie sind für gemäß Patent-Anspruch vorgesehene Produkte nicht verwendbar, weil sie generell grob und auch zu schwer sind.It is known to impregnate, squeeze or scrape open tissues with PVC plastisols and then gelled or foamed. Such articles are used for many purposes like Carpet pads, tablecloths and the like are used. All known and manufactured in this way Articles are surrounded on both sides with PVC and are delivered in a very open structure. they are not usable for products provided according to patent claim, because they are generally coarse and are too heavy.

Anwendungsbeispiel zum PatentanspruchApplication example for claim

Erfindungsgemäß wird aber ein sehr festes, dehnbares Gewirke, vorzugsweise aus Polyesterfasern hergestellt, im Umkehrverfahren so beschichtet, dass man PVC-Plastisole jeglichen Weichheitsgrades und vorzugsweise mit thixotroper Rheologie und relativ geringem Auftragsgewicht auf das Trennpapier aufträgt, das Gewirke in die noch ungelierte Paste mit Druck einlaminiert und mit sehr geringer Temperatur vorgeliert, sodass der PVC-Film sich noch in brüchigem Gelzustand befindet.According to the invention, however, a very strong, stretchable knitted fabric is preferably made from Polyester fibers produced, coated in the reverse process so that PVC plastisols any degree of softness and preferably with thixotropic rheology and relatively low Apply the application weight to the release paper, then add the knitted fabric to the ungelled paste Laminated pressure and pre-gelled at a very low temperature, so that the PVC film is still is in a brittle gel state.

Unmittelbar nach der so gearteten Vorgelierung wird das Produkt vom Trennpapier abgezogen und sofort (oder, falls nicht maschinengemäß möglich, auch in getrenntem Arbeitsgang) in einen Spannrahmen geführt, auf dessen Einlauffeld die noch vorgelierte Ware sich in beiden oder auch nur einer Richtung recken lässt. Die Reckung resp. das Dehnen muss in noch vorgeliertem Zustand der abgezogenen Warenbahn erfolgen, während man dann im Gelierkanal das bereits gereckte, offene Produkt in beliebiger Weise ausgelieren oder schäumen lässt. Es entsteht, je nach Gewicht und Schaumfähigkeit der Beschichtung oder des Schäumungsgrades, eine sehr textilartige, voll luftdurchlässige Ware mit unbeschichteter Rückseite.Immediately after the pre-gelation of this type, the product is removed from the release paper and immediately (or, if not machine-compatible, also in a separate operation) into one Tensioning frame guided, on the infeed area of the still pre-gelled goods in both or can only stretch in one direction. The stretching or stretching must still be pre-gelled Condition of the removed web is done while you are already in the gelling channel stretched out, open product in any way. It arises, ever by weight and foamability of the coating or the degree of foaming, a very textile-like, fully air-permeable fabric with an uncoated back.

Die Luftdurchlässigkeit und den Grad des textilen Charakters kann man sehr bequem regeln mit:
Pastengewicht, Schaumfähigkeit, Schäumungsgrad und Reckungsgrad der Ware im Einlauffeld in beiden Richtungen.The air permeability and the degree of the textile character can be regulated very easily with:
Paste weight, foamability, degree of foaming and degree of stretching of the goods in the inlet area in both directions.

Diese Produkte zeigen, abhängig von der Gewirkestruktur, bereits beim Verlassen des Gelierkanals eine wundervolle textile Struktur, können aber auch vorsichtig geprägt werden, wobei darauf zu achten ist, dass der Prägedruck bei zu großer Auflage die Schauminseln nicht schließt. Depending on the knitted structure, these products show when you leave the Gelling channel a wonderful textile structure, but can also be carefully shaped, it should be ensured that the embossing pressure does not affect the foam islands if the print run is too large closes.  

Wenn eine geeignete "in-line"-Beschichtungsanlage mit zahlreichen Auftragsmaschinen zur Verfügung steht, kann das Produkt auch in-line mit Schlussstrichen und mehrfarbigem Pastendruck versehen werden. Hier ist darauf zu achten, dass auch Schlusslacke und Druckpasten verwendet werden, die vor dem Öffnen der Warenbahn im Spannrahmen keinen elastischen Film ergeben (z. B. "Dispersions-Schlusslacke").If a suitable "in-line" coating system with numerous coating machines for Is available, the product can also be in-line with bottom lines and multi-colored Paste printing. It is important to ensure that top coats and Printing pastes are used that do not exist in the stenter before opening the web elastic film (eg "dispersion top coats").

Die so erzeugten Artikel textilartigen Aussehens und besonders guter Abriebfestigkeit sowie extremer Luftdurchlässigkeit werden verwendet für Sesselbezüge, vorwiegend auch Strandliegestühle (schmutzunempfindlich!), aber auch in leichtester Ausführung für preisgünstige Bezüge von Sonnenschirmen mit verringertem Hitzestau, als Teppichunterlagen, Filter vieler Art, aber auch für auf Schnee rutschmindernde Skibekleidung mit ausgezeichneter Luftdurchlässigkeit, bei geeigneter Imprägnierung (wasserabstoßender Oberfläche!) für haltbare, angenehm tragbare Armeebekleidung.The articles produced textile-like appearance and particularly good abrasion resistance as well Extreme air permeability is used for armchair covers, mostly too Beach chairs (insensitive to dirt!), But also in the lightest version for inexpensive covers for parasols with reduced heat build-up, as carpet underlays, Filters of many types, but also for ski clothing with excellent anti-slip properties on snow Air permeability, with suitable impregnation (water-repellent surface!) For durable, comfortable wearable army clothing.

Das nach unten hin unbeschichtete Polyestergewebe ist sehr reißfest, das Produkt kann mit geeigneter Imprägnierung schmutzabweisend behandelt werden (Scotchgard, z. B.).The downward uncoated polyester fabric is very tear-resistant, the product can with be treated with a suitable impregnation to repel dirt (Scotchgard, e.g.).

Für "heavy duty"-Produkte wie Auto-Sitzbezüge kann das Material mit einem weiteren, die Reißfestigkeit verbessernden Gewebe oder Gewirke laminiert werden, wobei Baumwollgewebe wegen ihrer Feuchtigkeitsaufnahme vorzuziehen sind. Gleiches gilt für die Verwendung von wasserabstoßend ausgerüstetem Schuhmaterial.For "heavy duty" products like car seat covers, the material can be combined with another that Tear strength-enhancing fabrics or knitted fabrics are laminated with cotton fabrics are preferable because of their moisture absorption. The same applies to the use of water-repellent shoe material.

Die erfindungsgemäß erzeugten Materialien sind ausgesprochen billig herzustellen, weil bereits Plasisolauflagen ab 80 g/qm ausreichen, um attraktive und gebrauchstüchtige Artikel zu erzeugen. Bei Auflagen über 180 g/qm werden bereits sehr treibmittelarme Pasteneinstellungen benötigt, um Schönheit und Luftdurchlässigkeit zu bewahren. Es können Plastisole jeglichen Weichmacheranteils verwendet werden und müssen naturgemäß hinsichtlich Kältebeständigkeit und Weichmacherflüchtigkeit dem jeweiligen Verwendungszweck angepasst werden.The materials produced according to the invention are extremely cheap to manufacture because they already do Plasole pads from 80 g / sqm are sufficient to make attractive and usable items produce. In the case of runs of more than 180 g / sqm, paste settings that are very low in blowing agent are already made needed to preserve beauty and breathability. Plastisols can do any Plasticizer portion are used and must naturally with regard to cold resistance and volatility of plasticizers are adapted to the respective purpose.
