摘要
The present invention consists of compounds and reactive nanoparticles with insect repellent activity on textile substrates and other materials and respective process of preparation and binding hydrolysable silanes through a process in which ethyl 3 (N-n-butyl-N-acetylamine) propionate is added to a hydrolysable silane to form a compound that can be bound chemically to fibres or other functional materials. To the product resulting from this reaction a solution of silicate and triton can be added in a sol-gel process, to form reactive silica nanoparticles containing the ethyl 3 (N-n-butyl-N-acetylamine) propionate that are precipitated by lowering the pH. The active product is therefore preferentially but not exclusively included in silica nanoparticles. These nanoparticles have reactive groups that bind by covalent bonds to cellulosic fibres.
