US Patent 7517428 Production of self-cleaning surfaces on textile coatings

The invention relates to a process for producing self-cleaning surfaces on coated textile sheets, by the following steps of the process:i.) applying hydrophobic nanostructured particles to a surface of a transfer-medium sheet,ii.) applying a coating composition and a textile sheet to those surfaces of the transfer medium to which the hydrophobic nanostructured particles were applied in step i.) of the process,iii.) heat treatment of the composite resulting from steps i.) to ii.) of the process, andiv.) removing the transfer medium,and also to the coated textile sheets produced by means of the process of the invention, and their use.
