Abstract

A compact, water vapour permeable, thermally activated film of a polyurethane is produced on reversal paper and laminated onto a textile sheet material without additional adhesive.

Description

Wasserdampfdurchlässige, jedoch wasserdichte Materialien werden in stei­ gendem Maße für Sportbekleidung, Berufsbekleidung, Schuhe und vieles andere eingesetzt. Es gibt grundsätzlich vier Möglichkeiten, um das gewünsch­ te Resultat - Sperre für flüssiges Wasser, jedoch Durchlaß für Wasser­ dampf - zu erreichen:Water-vapor-permeable but waterproof materials are made of stei suitable for sportswear, workwear, shoes and much more others used. There are basically four ways to get what you want Result - lock for liquid water, but passage for water steam - to reach:

  • - die mikroporöse Membran;- the microporous membrane;
  • - die mikroporöse Beschichtung;- the microporous coating;
  • - die wasserdampfdurchlässige Kompaktbeschichtung;- The water vapor permeable compact coating;
  • - die wasserdampfdurchlässige Folie.- The water vapor permeable film.

Die mikroporöse Membran, z. B. die Membran der Fa. Gore, besitzt eine große Anzahl von Mikroporen, die Wasserdampf, aber keine Wassertröpfchen hindurchlassen; dafür ist die Oberflächenspannung des Wassers viel zu hoch. Die Membran wird üblicherweise punktförmig mittels eines Spezial­ klebers auf einen textilen Träger kaschiert. An den Klebestellen ist die Membran blockiert.The microporous membrane, e.g. B. the membrane from Gore has one large number of micropores that contain water vapor but no water droplets let through; but the surface tension of the water is much too high. The membrane is usually punctiform using a special glued onto a textile backing. At the glue points is the Membrane blocked.

Die mikroporösen Beschichtungen bestehen aus Polyurethan, welches nach dem Aufrakeln zum Koagulieren gebracht wird, wobei bestimmte Systeme teilweise vorkoaguliert sind. Die Poren sind größer als die der mikropo­ rösen Membran, auch ist die Porenverteilung ungünstiger, jedoch ist die Beanspruchbarkeit sehr hoch.The microporous coatings consist of polyurethane, which according to the doctor blade is coagulated, using certain systems are partially precoagulated. The pores are larger than those of the mikropo red membrane, also the pore distribution is less favorable, however Resilience very high.

Wasserdampfdurchlässige Kompaktbeschichtungen können auf unterschiedli­ cher Basis sein (Acrylate, Polyurethane, PVC-Verschnitte), wobei es nun darauf ankommt, daß genügend hydrophile Gruppen vorhanden sind. Die Was­ serdampfmigration geht notgedrungen gepaart mit einer Quellung. Water vapor permeable compact coatings can differ cher basis (acrylates, polyurethanes, PVC blends), where it now depends on the presence of sufficient hydrophilic groups. The what Steam migration is inevitably paired with swelling.  

Als letzter Vertreter der wasserdampfdurchlässigen Materialien sind Folien zu erwähnen, welche nach dem Prinzip der wasserdampfdurchlässigen Kompaktbeschichtung arbeiten und daher auch etwas quellen, wenn sie Wasser aufnehmen. Ein bekannter Vertreter ist die Enka Sympatex-Folie auf Polyesterbasis. Derartige Folien werden mittels punktförmig aufgetra­ gener Klebepunkte auf den Träger kaschiert. Dadurch geht ein Teil der Wasserdampfdurchlässigkeit verloren.As the last representative of the water vapor permeable materials To mention films that are based on the principle of water vapor permeable Compact coating work and therefore swell something when they Absorb water. A well-known representative is the Enka Sympatex film based on polyester. Such foils are applied in a punctiform manner gener adhesive dots laminated on the carrier. This is part of the Water vapor permeability lost.

Es war Ziel der vorliegenden Erfindung, einen Weg zu finden, um wasser­ dampfdurchlässige Folien ohne den störenden Kleberpunkt auf einen Träger aufzubringen. Die Bayer AG, Leverkusen, hat Lösungen aromatischer und aliphatischer Polyurethane zur Herstellung von wasser­ dampfdurchlässigen, elastischen PUR-Beschichtungen entwickelt.The aim of the present invention was to find a way to water vapor-permeable films without the annoying glue point on a carrier to apply. Bayer AG, Leverkusen, has more aromatic solutions and aliphatic polyurethanes for the production of water vapor permeable, elastic PUR coatings developed.

Hiermit können sowohl Direkt- wie auch Umkehrbeschichtungen hergestellt werden. Es lag nun nahe, einen auf Umkehrpapier aufgerakelten Film mit Kleberpunkten zu versehen, auf den Träger aufzukaschieren und das Papier abzuziehen. Obschon auf diese Weise gute Haftungen - insbesondere bei Verwendung eines PUR-Schmelzkleber-Webbs der Fa. Bonded Fibre Fabric Ltd. - erzielt wurden, blieb doch der Nachteil des wasserdampfundurchläs­ sigen Kleberpunkts bestehen.Both direct and reverse coatings can be produced with this will. It was only natural to have a film squeegee on reversal paper To provide glue points, to laminate on the carrier and the paper deduct. Although in this way good guarantees - especially with Use of a PUR hot-melt adhesive web from Bonded Fiber Fabric Ltd. - were achieved, the disadvantage of water vapor impermeability remained there are some glue spots.

Es wurde nun überraschenderweise gefunden, daß sich der auf dem Papier befindende PUR-Film ohne Kleberpunkt, aber auch ohne Schädigung des Films, in einem ausreichend breiten Temperaturband auf den Träger ther­ misch kaschieren läßt. Das erfindungsgemäße Verfahren besteht somit aus folgenden Stufen:It has now surprisingly been found that the on paper PU film without adhesive point, but also without damaging the Films, in a sufficiently wide temperature band on the carrier ther mix laminates. The method according to the invention thus consists of following levels:

  • - Aufrakeln der PUR-Lösung auf Umkehrpapier und Bildung des PUR-Films;- doctoring the PUR solution on reverse paper and forming the PUR film;
  • - thermisch kaschieren auf Träger;- thermal lamination on carrier;
  • - Abziehen des Papiers.- Peel off the paper.

Gegenüber Materialien, welche mit der bekannten, wasserdampfdurchlässi­ gen PES-Folie kaschiert sind, bietet das erfindungsgemäße Verfahren große Vorteile:Compared to materials with the well-known, water vapor permeable are laminated against PES film, the method according to the invention offers  big advantages:

  • - der Träger kann dehnbar sein (Wirkware);- The carrier can be stretchy (knitted fabric);
  • - viel weicherer Griff;- much softer grip;
  • - keine, die Wasserdampfdurchlässigkeit beeinträchtigenden Kleberpunkte.- no glue points that impair the water vapor permeability.

Andererseits bewirkt die vollflächige Verschweißung mit dem Substrat eine beträchtliche Erhöhung der mechanischen Beanspruchbarkeit.On the other hand, the full-surface welding to the substrate a significant increase in mechanical strength.

Im weiteren Verlauf wurde gefunden, daß sich das erfindungsgemäße Verfah­ ren für jeden thermoplastischen Kunststoff mit ausreichender Wasserdampf­ durchlässigkeit eignet, vorausgesetzt, daß sich ein geeigneter Film auf Trennpapier herstellen läßt. Dabei kann sowohl aus Lösung mit Dispersio­ nen, aber auch mit lösemittelfreien bzw. lösemittelarmen Produkten, wie z. B. präpolymere, maskierte Isocyanate der Familie der "High Solids" ge­ arbeitet werden. Andererseits können auch Verschnitte von Kunststoffen, z. B. eine Dispersion eines hydrophilen Acrylats mit einer solchen eines thermoplastischen Polyurethans, zur Anwendung kommen. Wichtig ist, daß mindestens eine Harzkomponente mit hydrophilen Gruppen und mindestens eine verschweißbare Harzkomponente vorhanden sind. Es gibt hier eine be­ trächtliche Anzahl von Möglichkeiten, die, einmal die Idee offenbart, dem Fachmann zugänglich sind.In the further course it was found that the method according to the invention ren for every thermoplastic with sufficient water vapor permeability, provided that a suitable film is on Release paper can be made. Both from solution with Dispersio nen, but also with solvent-free or low-solvent products, such as e.g. B. prepolymer, masked isocyanates of the family of "high solids" ge be working. On the other hand, blends of plastics, e.g. B. a dispersion of a hydrophilic acrylate with such a thermoplastic polyurethane. It's important, that at least one resin component with hydrophilic groups and at least a weldable resin component is present. There is a be here substantial number of ways that once the idea is revealed are accessible to the specialist.
