The invention relates to calendered web products with surfaces which have self-cleaning properties, and also to a simple process for producing these self-cleaning surfaces. The process of the invention is very simple, since it can utilize existing equipment. Calenders are usually used to produce web products from high-melt-viscosity polymers or web products with a fabric core. The process of the invention utilizes these calenders by applying microparticles on at least one roll of the calender. During passage of the webs, the microparticles are transferred to these via impression of the particles into the surface of the web products. The process of the invention provides access to self-cleaning surfaces which have particles with a fissured structure, without any need to apply an additional embossed layer or carrier layer of foreign material to the web products. Examples of uses of web products of the invention are truck tarpaulins, protective tarpaulins, awnings, sunshade roofs, and tenting. |
