Abstract
trata-se de panos não tecido adequados para uma ampla variedade de aplicações (por exemplo, cuidados de saúde, filtragem, industrial, empacotamento, etc.). em um aspecto, o pano não tecido inclui uma pluralidade de fibras segmentadas. cada uma dentre a pluralidade de fibras segmentadas pode compreender um eixo geométrico de fibra e uma pluralidade de segmentos de diâmetro maior e diâmetro menor alternantes ao longo do eixo geométrico de fibra. a pluralidade de fibras segmentadas pode ser alinhada substancialmente em uma primeira direção.
