Abstract

A process for producing anti-allergic surfaces, and articles which comprise these anti-allergic surfaces. The process of the invention produces anti-allergic surfaces. The basis of the anti-allergic action is that self-cleaning properties make it impossible or very difficult for allergenic substances to deposit on these surfaces, and make it possible for them to be cleaned from the surface by a simple cleaning procedure using water set in motion. The surfaces may be either textile surfaces or polymer surfaces. Structures composed of elevations and depressions, as have been described on many previous occasions, are applied to these surfaces. The coatings of the invention can be applied very simply by applying a dispersion of suitable particles in a solvent to the relevant surface and then removing the solvent. Textiles, mattresses, or covers, for example, can be provided with the anti-allergic surfaces of the invention.
