Abstract: A composite membrane including at least one fabric, the membrane including a surface polymer layer, the surface polymer layer including silver and at least one polymer selected from the group formed by fluorinated polymers and silicones, and the membrane being such that silver is in the form of silver supported by a mineral matrix in powder form, the particle size of the matrix being strictly larger than 0.1 ?m and strictly smaller than 20 ?m. A method for manufacturing a membrane according to the invention. A use of a membrane according to the invention as a virucide.

Abstract: A coated textile contains a web based on glass fibres having a back face, a front face and at least one edge. The front face is covered with a coating layer based on silicone and back face is capable of being bonded to a support. The coating layer has a thickness between 5 ?m and 250 ?m and includes at least one inorganic flame retardant compound in a quantity which is sufficient for the coated textile to have a gross calorific value of less than or equal to 3 MJ/kg, the inorganic flame retardant compound having a D50 granule size of less than 50 ?m.

Abstract: A method for functionalising a textile substrate made of a hydrophilic material in order to impart humidity transfer properties thereto, wherein the method includes the steps of: preparing a formulation of at least one hydrophobic material containing at least one group reacting under ionising radiation; forming a discontinuous layer using the formulation on a surface of the textile substrate; and applying an ionising radiation onto the discontinuous layer in order to graft the hydrophobic material on the surface of the substrate by the reaction of the reactive groups.
