Abstract

Ce procédé servant à déposer une substance ou un mélange de substances sur les fibres d'un matériau fibreux, notamment d'un matériau à base de fibres minérales, consiste à faire pénétrer dans le matériau fibreux chaque substance ou un matériau précurseur de celle-ci, à l'état gazeux, à une température supérieure à celle du matériau fibreux, ces substances, ou de préférence une partie de celles-ci, étant déposées sur les fibres par condensation. On peut mélanger la substance ou son précurseur avec un gaz de transport possédant un point de rosée sensiblement inférieur à celui de la substance de manière à former un mélange gazeux polynaire que l'on fait pénétrer dans le matériau fibreux, lequel est maintenu à une température inférieure au point de rosée du mélange gazeux afin qu'une partie de la substance ou du précurseur de celle-ci soit déposée sur les fibres par condensation.
