    Abstract: The invention relates to a textile structure, intended to be used as a sound-absorbing structure in acoustic ceiling panels and/or acoustic wall panels, consisting of (a) a nonwoven mat of glass fibers bound by a thermoset binder, the nonwoven mat having a surface density of between 20 and 200 g/m2 and (b) a continuous acoustic layer comprising from 80% to 95% by weight of particles, preferably mineral particles, and from 5% to 20% by weight of a thermoplastic polymer and/or elastomer binder, the textile structure having an open porosity of greater than 3%, preferably between 4% and 60%, and a static airflow resistance (determined according to the standard ISO 9053) of between 1000 and 3000 N·s·m−3, said continuous acoustic layer at least partially impregnating said nonwoven mat, and the particle size distribution of the particles having a D10 of between 0.1 and 0.5 μm. It also relates to a process for manufacturing such a textile structure and to a ceiling panel or wall panel coated on one of these faces with such a textile structure.

    Abstract: A luminous woven fabric comprises a woven textile support comprising warp yarns and weft yarns selected from binding yarns and optical fibers capable of emitting light sideways. The binding yarns comprise glass yarns representing at least 50% by weight relative to the total weight of the binding yarns forming the woven textile support.

    Abstract: The invention relates to an aqueous binder composition containing, relative to the total dry weight of the binder composition, 10 to 40% by weight of a hydrogenated sugar, 25 to 55% by weight of citric acid, 25 to 50% by weight of a polysaccharide, and 1 to 10%, preferably 2 to 6%, by weight, of sodium hypophosphite or hypophosphorous acid. The polysaccharide is dissolved in the aqueous binder composition and chosen from functionalized starches and dextrins having a weight-average molar mass of between 150,000 and 2,000,000 and a solubility in water of between 50 and 85%. The invention also relates to a method for manufacturing non-woven webs based on mineral or organic fibers using such a composition and the non-woven webs thus obtained.
