PROCEDIMENTO DI TRATTAMENTO DI MATERIALI FIBROSI PER OTTENERE PROPRIETA' IDROREPELLENTI, MATERIALI FIBROSI IDROFOBICI ED ARTICOLI CHE LI COMPRENDONO COSI' OTTENUTI

摘要

Process for treating a fibrous material, to make said material hydrophobic and/or water-repellent, comprising the operation of impregnating said material with a suspension comprising nanoparticles of a hydrophobic material and a cyanoacrylate in an organic solvent and causing the crosslinking of said cyanoacrylate; the process uses an amount of cyanoacrylate and a weight ratio with the nanoparticles such as to produce complete or partial coating of the fibrous material with a matrix of crosslinked cyanoacrylate in which said nanoparticles are dispersed.
