Abstract

PANO NÃO TECIDO QUE TEM DE ALTA RESISTÊNCIA TÉRMICA E PROPRIEDADES DE BARREIRA. Trata-se de panos não tecidos que incluem uma primeira camada de fiação contínua mais externa, uma segunda camada de fiação contínua mais externa e pelo menos uma primeira camada produzida por sopro em fusão e/ou fibrilada por fusão disposta direta ou indiretamente entre a primeira camada de fiação contínua mais externa e a segunda camada de fiação contínua mais externa. A primeira camada de fiação contínua mais externa compreende uma primeira pluralidade de fibras contínuas que são termicamente fundidas e compactadas umas contra as outras e definem um filme microporoso em uma superfície mais externa do pano não tecido. A primeira pluralidade de fibras contínuas compreende uma primeira composição polimérica que tem um primeiro ponto de fusão, e a primeira camada produzida por sopro em fusão e/ou camada fibrilada por fusão compreende uma primeira pluralidade de fibras produzidas por sopro em fusão e/ou fibras fibriladas por fusão que compreende uma terceira composição polimérica que tem uma terceira ponto de fusão, em que o primeiro ponto de fusão é inferior ao terceiro ponto de fusão.
