Title (EN) NATURAL OR SYNTHETIC YARNS WITH HEAT TRANSMISSION BARRIER PROPERTY OBTAINED BY AEROGEL DEPOSITION
(FR) FILS NATURELS OU SYNTHETIQUES POSSEDANT DES PROPRIETES DE BARRIERE CONTRE LA TRANSMISSION DE CHALEUR OBTENUES PAR DEPOSITION D'AEROGEL DEPOSITION
Abstract: front page image
(EN)Production of natural or synthetic yarns with heat transmission barrier property, obtained by deposition of non-hypercritical synthesized aerogel. Characterized by high porosity, the aerogel confers to the yarn thermal insulation properties. This enables the production of fabrics which can be utilized, as an example, under hot and cold extreme conditions. The invention is characterized by a new technique of aerogel non-hypercritical synthesis and by a process of aerogel deposition by impregnation and then yarn exposition to the UV-rays.
(FR)L'invention concerne la production de fils naturels ou synthétiques possédant des propriétés de barrière contre la transmission de chaleur, obtenues par déposition d'aérogel synthétisé non hypercritique. Grâce à sa porosité élevée, l'aérogel confère aux fils des propriétés d'isolation thermique. Cette caractéristique permet de produire des tissus qui peuvent être utilisés, par exemple, dans des conditions extrêmement chaudes et froides. L'invention concerne ainsi une nouvelle technique de synthèse non hypercritique d'aérogel et un procédé de déposition d'aérogel par imprégnation, puis d'exposition des fils aux rayons ultraviolets.
