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).
EMI0001.0031
  
    <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.
