The invention relates to calendered sheet articles having surfaces, which have self-cleaning properties, and to a simple method for producing self-cleaning surfaces of this type. The inventive method is very simple by virtue of the fact that it can involve the use of existing tools. Sheet articles made of polymers having a high melting viscosity or sheet articles having a woven fabric core are generally produced by using calenders. The inventive method involves the use of these calenders by applying microparticles to at least one roller of the calender. As the sheets are passed by, these microparticles are transferred thereto while being pressed into the surface of the sheet articles. The inventive method makes it possible to obtain self-cleaning surfaces comprising particles with a fissured structure without having to apply an additional embossed layer or foreign material supporting layer to the sheet articles. The inventive sheet articles can be used, for example, as automotive truck tarpaulins, covering tarpaulins, awnings, sunshading roofs or tent tarpaulins. |
