Abstract

separador com resistência aumentada à perfuração. a presente invenção refere-se a um separador com um corpo básico de não tecido, em que o corpo básico é provido de um revestimento, em que o revestimento contém partículas de material de enchimento e celulose, em que o revestimento contém partículas orgânicas flexíveis de ligante e em que as partículas de material de enchimento e as partículas orgânicas flexíveis de ligante estão ligadas umas com as outras através de celulose, com respeito ao objetivo, é configurar e desenvolver um separador de modo tal, que este, com uma estabilidade mecânica aumentada, mostra uma lata permeabilidade, caracterizado pelo fato de que a celulose contém derivados de celulose, que apresentam um comprimento de cadeia de pelo menos 100 unidades de repetição, preferivelmente um comprimento de cadeia de pelo menos 200 unidades de repetição.
