The present invention relates to textile sheetlike constructions having an enhanced watertightness and also to a process for producing them. It was found that, surprisingly, the watertightness of porous textile sheetlike constructions is enhanced when a coating of hydrophobic particles having an average particle size in the range from 0.02 to 100 μm is applied to the surfaces of the fibers. The textile sheetlike constructions can be used for example as textile building materials or for producing tents, umbrellas or the like. |
