Abstract

PROCESSO DE OBTENçãO DE ARTIGO CONTENDO NANOFBIRAS E ARTIGO NãO-TECIDO CONTENDO NANOFIBRAS. A presente invenção refere-se a um processo de fabricação de um artigo não-tecido contendo nanofibras e a um artigo não-tecido contendo nanofibras. Estes artigos podem ser utilizados como filtros para sistemas que contenham partículas, tais como membranas de separação usadas na indústria têxtil, células, solventes polares, ou como sensores de umidade e outros sensores, e também para aplicações na indústria de tecelagem. O processo, de acordo com a invenção, consiste na conversão de uma solução de poliamidas em nanofibras com um diâmetro médio entre aproximadamente 40 nm e 350 nm por eletrofiação.
