Abstract (en)
[origin: WO2016120573A1] The subject matter of the present invention is a process for treating a substrate with a view to improving the properties thereof in terms of absorption of malodorous molecules, in particular linked to sweat, comprising the following steps: (i) preparing an acid aqueous composition, comprising at least one organosilane A having at least one hydrolysable group and at least one principal polycarboxylic acid B comprising at least four carboxyl groups -COOH or the corresponding anhydride thereof comprising at least four groups -COO-CO; the ratio of the weight of said at least one organosilane A to the weight of said at least one principal polycarboxylic acid B is between 0.8 and 1.2; (ii) applying said composition to said substrate, (iii) heating said substrate comprising said composition at a temperature greater than or equal to 120°C, preferably greater than or equal to 130°C, in order to polymerize said organosilane A with at least the principal polycarboxylic acid B or the corresponding anhydride thereof.
