Abstract

MEIOS DE FILTRAÇÃO. Esta revelação descreve um meio de filtração que é, de preferência, isento de vidro ou substancialmente isento de vidro. Em algumas modalidades, o meio de filtração exibe, de preferência, capacidade e eficiência comparáveis ou melhores que meios de filtração contendo vidro similares. O meio de filtração inclui fibras bicomponentes, fibras de eficiência (por exemplo, fibras de PET) e fibras microfibriladas. As fibras de eficiência incluem fibras que têm um diâmetro de fibra em uma faixa de 1 mícron a 5 mícrons e fibras que têm um diâmetro de fibra de pelo menos 0,1 mícron e inferior a 1 mícron.
