Abstract

MÉTODO DE FABRICAÇÃO DE UMA MANTA NÃO TECIDA, E,SISTEMA. Um sistema e método para fornecer uma pluralidade de fibras de uma fieira; submeter as fibras ao ar de têmpera; atenuar as fibras através de uma unidade de estiramento fechada; reduzir uma velocidade da pluralidade de fibras em um difusor que é espaçado de uma saída da unidade de alongamento fechada em uma direção de deslocamento das fibras, o difusor tendo paredes laterais divergentes opostas; e submeter as fibras a uma carga eletrostática aplicada antes das fibras entrarem no difusor, em que a carga eletrostática é aplicada por uma ou mais unidades de carga eletrostática.
