Producing a shaped article

Abstract

A shaped article is produced from a sheetlike fibrous nonwoven web and an aqueous polymeric dispersion.

2 : The method according to claim  1 , wherein the fibrous nonwoven web has a basis weight of ≧100 and ≦3000 g/m 2 . 
     
     
         3 : The method according to claim  1 , wherein the fibrous nonwoven web consists of lignocellulosic fibers. 
     
     
         4 : The method according to claim  1 , wherein an amount of the aqueous polymeric dispersion is determined such that from 1 to 100 g of the polymer are incorporated per 100 g of the fibrous nonwoven web. 
     
     
         5 : The method according to claim  1 , wherein the fibrous nonwoven web is dried in b) to a residual moisture content ≦20 wt %. 
     
     
         6 : The method according to claim  1 , wherein T o =Tg+≧10° C. 
     
     
         7 : The method according to claim  1 , wherein T u =Tg−(≧10)° C. 
     
     
         8 : The method according to claim  1 , wherein the fibrous nonwoven web is additionally precompressed to a thickness D c  in c), where the thickness D c  corresponds to the thickness D d +≦0.3 D d  obtained on completion of d). 
     
     
         9 : The method according to claim  1 , further comprising:
 c 1 ) applying a decorative material ≦10 mm in thickness atop either and/or both of the surfaces of the heated fibrous nonwoven web after c) and before d).   
     
     
         10 : The method according to  claim 9 , wherein the decorative material comprises a textile sheet material, a polymeric foil, a foamed sheet material or a foamed sheet material in turn coated with a textile sheet material, a polymeric foil or a further foamed sheet material on the surface which does not come into contact with the heated fibrous nonwoven web. 
     
     
         11 : The method according to claim  1 , wherein a) through d) are carried out continuously. 
     
     
         12 : A shaped article obtained by the method according to claim  1 . 
     
     
         13 : A method of constructing a vehicle, the method comprising
 incorporating the shaped article according to  claim 12  as a structural element into the vehicle.   
     
     
         14 : A process for producing a shaped article precursor from a fibrous nonwoven web and an aqueous polymer dispersion, the process comprising
 a) incorporating the aqueous polymeric dispersion whose polymer particles comprise a polymer having a glass transition temperature Tg≧35 and ≦130° C. into the fibrous nonwoven web, and   b) subsequently drying the fibrous nonwoven web thus treated to a residual moisture content ≦20 wt %.   
     
     
         15 : A shaped article precursor, obtained by the process according to  claim 14 . 
     
     
         16 : A method for producing a shaped article according to  claim 11 , the method comprising
 shaping the shaped article precursor according to  claim 15  into the shaped article.   
     
     
         17 : A method of constructing a built structure, the method comprising
 incorporating the shaped article according to  claim 12  as a structural element into the built structure.   
     
     
         18 : A method of constructing furniture, the method comprising
 incorporating the shaped article according to  claim 12  as a structural element into the furniture.
