1. A process for manufacturing a textile surface (1) with hydrophobic properties on one side (1′
- ) and hydrophilic properties on the other side (1″
), characterised in that, the textile surface (1) is hydrophilic in nature across its cross-section, that a paste (11) is applied to one side (1′
) of the textile surface (1) in a continuous process, this paste (11) comprising a emulsion or dispersion of paraffin, polysiloxane and/or fluorine compounds only penetrating the cross-section of the textile surface (1) over a partial area, and that the layer formed by the paste (11) is then stabilised in a drying process (4).

Abstract
The aim of the invention is to produce a textile surface (1), one side of which exhibits hydrophilic properties and the other side hydrophobic properties, whose overall cross-section is hydrophilic. To achieve this, a paste (11) consisting of a viscous emulsion or dispersion of paraffin, polysiloxane and/or fluorine compounds is applied to one side. The layer that has been formed by the first paste (11) is then stabilised by means of a drying process (4) and a second paste (12), consisting of a hydrophilic polymer is subsequently applied to the other side of the textile surface (1), said paste being stabilised by an additional drying process (5). Said steps provide a textile surface (1), which can be produced simply and cost-effectively, is extremely comfortable to wear and which ensures that moisture is immediately absorbed on the hydrophilic side, dispersed over a large area and rapidly removed, whereas the hydrophobic side of said textile surface (1) repels water.
