Patent FR-2542260-A1 (FR)
Inventor: DUFOREST
IPC: B05D5/06
Filed: 1984-03-08
Abstract: A process and apparatus for manufacturing synthetic decorative coverings is presented in which at least one powder (generally a polymeric resin) is selectively deposited, in accordance with a pattern or decoration, onto a base material. The power deposition is carried out under gravity without contact between the means of applying the powder and the base. At least one of the deposited powders contains particles which are fusible at a temperature below the distortion temperature of the base and which is compatible with the base material. At least one thermal treatment is then carried out at a temperature below the distortion temperature of the base so as to fix the decorative pattern produced by deposited powders. The apparatus for applying the powders consists of a continuous screen printing frame, in particular, a screen printing roller which is fed by a device providing uniform distribution of the powder into a hopper located inside the roller. The hopper has two longitudinal blades which are adjustably separated and are in contact with the inner surface of the screen.

Title: Sponges made hydrophilic, based on synthetic polymer and a process for their manufacture
Inventor: ARMAND XAVIER
IPC: C08J9/40
Filed: 1986-01-15
Abstract: Spongy products made hydrophilic, especially polyurethane, polyether or polyester sponges made hydrophilic. The treatment for making hydrophilic consists in grafting at least one hydrophilic monomer such as acrylic acid onto the surface of the spongy product, by a radical mechanism, in the presence of a peroxide such as aqueous hydrogen peroxide. The grafting may be carried out by irradiation by means of ionising radiations or by means of a ferrous salt, for example ferrous sulphate. The spongy products thus made hydrophilic exhibit a permanent hydrophilic nature and good wettability and water retention properties.
