1. A process for manufacturing a textile surface having hydrophobic properties on a first side of the textile surface and hydrophilic properties on a second side of the textile surface, comprising:

  • continuously applying an emulsion or dispersion comprising at least one component selected from the group consisting of;

    paraffin, polysiloxane and fluorine compounds, and 1 to 5 parts of a synthetic thickening agent or a natural thickening agent to the first side of the textile surface to form a first coating wherein the emulsion or dispersion is applied to the textile surface as a paste with a viscosity of 5,000 to 10,000 mPa·

    s,stabilizing the first coating in a first drying process,applying a composition comprising hydrophilic polymers to the second side of the textile surface to form a second coating, andstabilizing the second coating in a second drying process,wherein the textile surface is hydrophilic across its complete cross-section.
