Abstract (en)
Increasing the waterproofness of porous textiles comprises applying a suspension of particles in a solvent and removing the solvent so that the particles are fixed to the textile fibers to form a structure of elevations with a height 20 nm -100 mu m and a spacing of 20 nm -100 mu m. The particles have an average size of 0.02-100 mu m and are hydrophobic, or are nonhydrophobic and then hydrophobized. An independent claim is also included for textiles with increased waterproofness, comprising fibers with a hydrophobic surface structure of elevations with a height 20 nm to 100 mu m and a spacing of 20 nm to 100 mu m.
