Abstract

PROCESSO DE SEPARAÇÃO DO SOLVENTE. Um processo de separação do solvente de fiação quimicamente ligado partir de uma trama não-tecida fiada em solução compreendendo as etapas de fornecer uma trama não-tecida compreendendo fibras poliméricas carregadas de solventes possuindo um diâmetro médio inferior a cerca de 1 micrômetro, e transportando a trama não-tecida através de uma zona de separação do solvente em que a radiação infravermelha irradia a trama não-tecida e um fluido de separação do solvente afeta a trama não-tecida, a fim de reduzir a concentração de solvente das fibras para menos de cerca de 10.000 ppm em peso.
