Abstract

"TRAMA ELáSTICA RESPIRáVEL". Uma concretização da presente invenção se refere a uma trama elástica que pode ser feita respirável após aplicação de uma força de tensão tal como seria encontrada em certas aplicações, tais como fraldas e outros artigos higiênicos, e bandagens. A respirabilidade é alcançada pela inserção na trama de fendas cuja área aberta aumenta após aplicação de uma força na trama que age ao longo do eixo geométrico maior de referidas fendas.
