Abstract
"MATERIAL COMPOSTO COM MELHOR ADMISSãO DE FLUIDO DE ALTA VISCOSIDADE". Sistema de forro adequado para uso em produtos absorventes de higiene pessoal que têm um material composto que inclui uma subestrutura aplicada à primeira camada. A primeira camada e a subestrutura definem uma pluralidade de lacunas para acomodar a passagem de fluidos através do material composto. Em uma modalidade, fluidos de alta viscosidade que incluem as partículas contidas naqueles atravessam uma pluralidade de aberturas na primeira camada. As lacunas definidas pela primeira camada e pela subestrutura aprisionam as partículas para acomodar a passagem de fluidos através do material composto.
