Description
Verfahren zur Herstellung von wasserdampf- und luftdurchlässigen Flächengebilden Zur Herstellung von wasserdampf- und luftdurch lässigen Flächengebilden wird nach dem Patentan spruch des Hauptpatentes eine Vinylchloridpolymeri- sat oder -mischpolymerisat enthaltende Paste mit Polyvinylverbindungen, die mindestens teilweise aus Vinylalkoholeinheiten (-CH.- CHOR) zusammen gesetzt sind, und die in einer verdampfbaren Flüssig keit gelöst sind, vermischt,
die Mischung zu einer Schicht verteilt und diese einer Wärmebehandlung unterworfen, durch welche die genannte verdampf- bare Flüssigkeit verdampft und die Masse geliert wird.
Es wurde nun gefunden, dass es bei diesem Ver fahren zweckmässig ist, die Polyvinylverbindungen, die mindestens teilweise aus Vinylalkoholeinheiten zusammengesetzt sind, in Form einer in Weichmacher emulgierten wässrigen Lösung mit der Vinylchlorid- polymerisat oder -mischpolymerisat enthaltenden Paste zu vermischen.
Um die Porenausbildung bzw. Porengrösse des Fertigproduktes zu beeinflussen, kann man der Emul sion der wässrigen Lösung der mindestens teilweise aus Vinylalkoholeinheiten zusammengesetzten Poly- vinylverbindungen in Weichmacher solche Stoffe in gelöster oder fester Form zusetzen, welche beim Ausgelieren der Paste Gase abspalten oder sich unter Gasbildung zersetzen. Stoffe dieser Art sind z. B.
Natriumbicarbonat, Ammoniumbicarbonat, Ammo- niumcarbonat, ferner Stoffe, die als Porophore (ein getragene Marke) im Handel sind.

<I>Beispiel <SEP> 1</I>
<tb> Zur <SEP> Herstellung <SEP> der <SEP> Emulsion <SEP> werden
<tb> 20 <SEP> Teile <SEP> Dioctylphthalat
<tb> 10 <SEP> Pigment
<tb> 0,5 <SEP> " <SEP> Stabilisator gemahlen. Dann werden 20 Teile Polyvinylalkohol in 80 Teilen Wasser gelöst und in obiger Masse emul- giert.
Eine vorgereifte Paste aus 50 Teilen Polyvinyl- chlorid und 30 Teilen Dioctylphthalat wird mit der polyvinylalkoholhaltigen Dispersion gemischt.
Die so erhaltene Paste wird mit 200 gim9 auf ein Creppgewebe aufgetragen, getrocknet und weitere 200 g/m2 aufgetragen. Nach Verdunsten des Wassers bei 85 bis 95 wird geliert und anschliessend ge narbt.
Das so erhaltene Flächengebilde weist eine Luft durchlässigkeit (DIN 53 334) von 18 limin und eine Wasserdampfdurchlässigkeit (DIN 53 333) von 172 auf.
<I>Beispiel 2</I> 10 Teile Polyvinylalkohol werden in einer durch Verdünnen von 4 Teilen einer 10%igen wässrigen Lösung des Ammoniumsalzes der Polyacrylsäure mit 40 Teilen Wasser erhaltenen Lösung gelöst. Dann werden 40 g Natriumacetat langsam unter gutem Rühren zugegeben, worauf die Lösung in einer aus 20 Teilen Tricresylphosphat und 0,5 Teilen Stabili sator bestehenden Mischung emulgiert wird.
Die so erhaltene Dispersion wird einer vorgereif- ten Paste aus 50 Teilen Polyvinylchlorid und 30 Tei len Tricresylphosphat zugesetzt und die Masse gut verrührt. Die Masse wird auf ein Gewebe aufgestri chen und nach dem Verdampfen des Wassers 20 Mi nuten bei 165 C geliert. Durch anschliessendes 30 Mi nuten langes Behandeln in einer 10%igen Borsäure lösung von 80 C wird das Natriumacetat aus dem erhaltenen Flächengebilde herausgelöst.
Das so hergestellte Flächengebilde besitzt eine Luftdurchlässigkeit (DIN 53 334) von 134 1/min und eine Wasserdampfdurchlässigkeit (DIN 53 333) von 200.
Process for the production of water-vapor and air-permeable sheet-like structures For the production of water-vapor- and air-permeable sheet-like structures, according to the patent claim of the main patent, a paste containing vinyl chloride polymer or -mischpolymerisat with polyvinyl compounds, which at least partially from vinyl alcohol units (-CH.- CHOR) together are set, and which are dissolved in a vaporizable liquid, mixed,
the mixture is distributed to form a layer and this is subjected to a heat treatment by means of which the said evaporable liquid evaporates and the mass is gelled.
It has now been found that in this process it is expedient to mix the polyvinyl compounds, which are at least partially composed of vinyl alcohol units, in the form of an aqueous solution emulsified in plasticizer with the paste containing vinyl chloride polymer or copolymer.
In order to influence the pore formation or pore size of the finished product, substances in dissolved or solid form can be added to the emulsion of the aqueous solution of the polyvinyl compounds, which are at least partially composed of vinyl alcohol units, in plasticizers which release gases or form gas when the paste gels decompose. Substances of this type are z. B.
Sodium bicarbonate, ammonium bicarbonate, ammonium carbonate, and also substances that are commercially available as porophores (a registered trademark).

<I> Example <SEP> 1 </I>
<tb> For <SEP> production <SEP> the <SEP> emulsion <SEP> will be
<tb> 20 <SEP> parts of <SEP> dioctyl phthalate
<tb> 10 <SEP> pigment
<tb> 0.5 <SEP> "<SEP> stabilizer ground. Then 20 parts of polyvinyl alcohol are dissolved in 80 parts of water and emulsified in the above mass.
A pre-ripened paste of 50 parts of polyvinyl chloride and 30 parts of dioctyl phthalate is mixed with the polyvinyl alcohol-containing dispersion.
The paste obtained in this way is applied to a crepe fabric with 200 g / m2, dried and a further 200 g / m2 are applied. After the water has evaporated at 85 to 95, it gels and then cicatrizes.
The flat structure thus obtained has an air permeability (DIN 53 334) of 18 limin and a water vapor permeability (DIN 53 333) of 172.
<I> Example 2 </I> 10 parts of polyvinyl alcohol are dissolved in a solution obtained by diluting 4 parts of a 10% strength aqueous solution of the ammonium salt of polyacrylic acid with 40 parts of water. Then 40 g of sodium acetate are slowly added with thorough stirring, whereupon the solution is emulsified in a mixture consisting of 20 parts of tricresyl phosphate and 0.5 parts of stabilizer.
The dispersion obtained in this way is added to a pre-ripened paste composed of 50 parts of polyvinyl chloride and 30 parts of tricresyl phosphate and the mass is stirred well. The mass is spread on a fabric and gelled at 165 C for 20 minutes after the water has evaporated. Subsequent treatment in a 10% boric acid solution at 80 ° C. for 30 minutes dissolves the sodium acetate from the sheet material obtained.
The fabric produced in this way has an air permeability (DIN 53 334) of 134 1 / min and a water vapor permeability (DIN 53 333) of 200.
