Abstract: A process of treating a resin-impregnated microfibrous non- woven matrix, characterized in that it includes the following treatment steps: - providing a microfibrous non- woven matrix having a top surface to be treated; - preparing said top surface of said matrix by hot calendering and/or buffing; - grouting said matrix by depositing and distributing a base resin coat thereon; - performing a micro-droplet spray deposition of one or more resins, a hot drying step being carried out on said matrix between the deposition of one layer and the deposition of the next layer, preferably an oven-drying step at a temperature ranging from 80°C to 150°C, more preferably at a temperature ranging from 90°C to 110°C; - hot embossing the surface of said matrix, said embossing step being carried out by partial melting of the fibers of said matrix, to cause a permanent deformation in said fibers of said matrix; - performing a micro-droplet spray deposition to form one or more continuous protective layers of one or more resins.
