Abstract

Uma trama não tecida spun bonded expandida hidroformada tem uma primeira superfície substancialmente plana num lado da mesma e uma segunda superfície num lado oposto da mesma. A segunda superfície inclui uma pluralidade de protuberâncias num padrão. A trama spun bonded expandida hidroformada tem um loft médio pelo menos cerca de 1,3 vezes maior do que um loft médio original de uma trama não tecida spun bonded não expandida original, a partir da qual a trama não tecida spun bonded expandida hidroformada foi criada, e uma permeabilidade ao ar pelo menos cerca de 1,2 vezes maior que a permeabilidade ao ar original da trama não tecida spun bonded não expandida original.
