Abstract: A system for the treatment of microorganisms includes: a textile web having optical fibers in warp and/or weft woven with binding threads in warp and/or weft, each of the optical fibers having invasive alterations along the fiber and allowing the emission of light propagating in the fiber at these alterations; a light source arranged opposite one or both free ends of the optical fibers. The textile web includes metallic warp and/or weft threads woven with the binding threads, the metallic threads being based on a metal having a negative effect on the growth of microorganisms. The light source generates a light beam having at least one wavelength in the visible or ultraviolet spectrum.

Abstract: The invention relates to a method for depositing metal particles on a textile support, which comprises: placing at least one textile sheet (1) made of side-emitting optical fibers (2) in contact with a solution containing at least one ionic precursor of a metal to be deposited, the textile sheet (1) being formed from optical fibers (2) woven in warp and/or weft with binding threads in warp and/or weft, each of the optical fibers (2) having invasive alterations (5) along the fiber and allowing the emission of light propagating in the fiber at these alterations (5), the textile sheet (1) being coated on all or part of the surfaces thereof with a layer of semiconductor particles (4) having photocatalytic properties, the textile sheet (1) and the solution being contained in a space of a reactor (9), the space being free of oxygen; illuminating the textile sheet (1) by at least one light source (7) connected to all or part of the free ends (6) of the optical fibers (2), the light source generating light radiati
