Abstract

Un metodo de cargar telas fibrosas con liquidos polares no acuosos. Una tela (20) que contiene fibras no conductoras es humedecida con un liquido polar no acuoso (14). La tela (20) es entonces substancialmente secada (22) para proporcionar una tela de electreto fibrosa. La tela de electreto fibrosa puede ser usada como un filtro en una mascarilla facial de filtracion (40) que es adaptada para cubrir la nariz y la boca del usuario. El presente metodo tiene la ventaja sobre los metodos de carga conocidos en que el liquido no acuoso requiere menos energia para secar que la que se requiere para liquidos acuosos. Adicionalmente, muchas telas de filtros pueden ser directamente humedecidas con liquidos no acuosos, las cuales no pueden ser facilmente humedecidas con liquidos acuosos.
