Abstract

The present invention is about a process of obtaining nanoparticles of silica, that involves the steps that are necessary for the dissolution of sodium silicate or trietheylortosilicate (TEOS) in water; addition of a solvent and the addition of an anionic tensoactive agent and stirring at room temperature to form a w/o emulsion and a sol-gel; addition of a product to encapsulate, hydrophilic or partially miscible in water, followed by stirring; addition of an acid or an acid salt continuing with the mixing; evaporation of the solvent so as to obtain the nanoparticles of silica. The invention is also about a process of immobilization and encapsulation of nanoparticles obtained in any of the claims from 1 to 10, by padding a textile material with the nanoparticles that involves a condensation polymerization reaction, during an alkaline washing of the material, so as to cause the encapsulation of the nanoparticles and the products in the pores of the 'nanoparticles, by forming a polymeric film around them.
