Abstract
"MéTODO PARA PRODUZIR UMA FOLHA CONTìNUA DE ELETRETO FIBROSA, MáSCARA DE FILTRAçãO, E, APARELHO PARA PRODUZIR UMA FOLHA CONTìNUA DE ELETRETO FIBROSA". Um método para conferir uma carga eletrostática a uma folha contínua fibrosa não-tecida (20). A folha continua fibrosa (20) é umedecido com um liquido umectante (24) sendo a seguir saturado com um líquido polar aquoso (30) e secado (31). O produto secado resultante é um artigo de eletreto (43), que poderia ser usado como um filtro de ar em, por exemplo, um respiradouro.
