Method for producing printed textiles for motor vehicles

Abstract

A method for producing printed textiles for motor vehicles, the textiles having a polyester-based top material and a bottom material, introduces at least a thickener and a UV absorber into the top material in a foulard process. The top material is dried, a digital printing process is carried out on the dried top material, and the printed top material is laminated with the bottom material. Dyes are applied such that the dyes are especially abrasion resistant. This is achieved in that, in the foulard process, a hydrophilizing agent is introduced into the top material.

1 . A method for producing printed textiles for motor vehicles, wherein the textiles have a polyester-based top material and a bottom material the method comprising the steps of:
 introducing at least a thickener and a UV absorber into the top material in a foulard process;   drying the top material;   carrying out a digital printing process on the dried top material;   laminating the printed top material with the bottom material;   applying colorless ink to the top material in the digital printing process when applying colored ink to the top material in the digital printing process.   
     
     
         2 . The method according to  claim 1 , wherein a hydrophilizing agent is introduced into the top material in the foulard process. 
     
     
         3 . The method according to  claim 1 , wherein a corona or plasma treatment is carried out prior to carrying out the digital printing process. 
     
     
         4 . The method according to  claim 1 , wherein the top material is subjected to an enzyme treatment prior to carrying out the foulard process. 
     
     
         5 . The method according to  claim 1 , wherein a deaerating agent is also introduced into the top material in the foulard process. 
     
     
         6 . The method according to  claim 1 , wherein a wetting agent is also introduced into the top material in the foulard process. 
     
     
         7 . The method according to  claim 1 , wherein the digital printing process is carried out using dispersion dyes and a drying takes place immediately thereafter. 
     
     
         8 . The method according to  claim 1 , wherein a fixing step, in response to which the ink is fixed, is carried out after the digital printing process. 
     
     
         9 . The method according to  claim 1 , wherein the top material is washed and dried after the digital printing process. 
     
     
         10 . The method according to  claim 1 , wherein the colorless ink is applied simultaneously with the colored ink by means of a separate print head. 
     
     
         11 . The method according to  claim 1 , wherein the colorless ink has the same or a very similar viscosity as the colored ink, which is added in the digital printing process. 
     
     
         12 . The method according to  claim 1 , wherein the colorless ink has colorless pigments. 
     
     
         13 . The method according to  claim 1 , wherein at least the same quantity of colorless ink as colored ink is applied for some bright hues. 
     
     
         14 . The method according to  claim 1 , wherein, across all dyes, the ratio of colorless ink as compared to colored inks is preferably at least 20% and maximally 50%. 
     
     
         15 . The method according to  claim 1 , wherein, across all dyes, a ratio of colorless ink as compared to colored inks is between 30% and 40%. 
     
     
         16 . The method according to  claim 1 , wherein more than twice as much colorless ink as colored ink is applied for some bright hues. 
     
     
         17 . The method according to  claim 1 , wherein more than three-times as much colorless ink than colored ink is applied for some bright hues.
