Application of nanosols prepared on the basis of precursors from organosilanes is one of methods used for nanostructuralization of textile surfaces focused on enhancement of their hydrophobic properties and achievement of a self-cleaning effect (lotus effect). Own results of preparation of the nanosols achieved up to now and their application on selected textiles are presented in the lecture. Besides methods for evaluation of superhydrophobic properties (rolling angle, wetting angle, dynamic angle, REM images etc.) are mentioned as well. Ways how to achieve permanent superhydrophobic finish of textiles are indicated in next part of the presentation.%Vyu?itie nanosólov pripravenych na báze prekurzorov z organosilánov je jeden zo spósobov nano?trukturalizácie textilnych povrchov s ciel'om zvy?enia ich hydrofóbnych vlastností s dosiahnutím efektu samo?istenia (lotosovy efekt). V príspevku sú prezentované doteraj?ie vlastné vysledky p?ípravy nanosólov a ich aplikácie na vybrané textilie. Zároveň sú uvedené metody pre hodnotenie superhydrofóbnych vlastností (uhol rolovania, uhol zmá?ania, dynamicky uhol, REM snímky at?.). ?alej sú nazna?ené spósoby dosiahnutia permanentnej superhydrofóbnej úpravy textilií.
