Abstract
UNA ESTRUCTURA ABSORBENTE CON CAPACIDADES DE ABSORCION CAPILAR Y OSMOTICA. LA ESTRUCTURA ABSORBENTE CONSTA DE UN SUSTRATO ABSORBENTE CAPILAR, TAL COMO PAPEL. EL SUSTRATO TIENE SECCIONES CON DENSIDADES RELATIVAMENTE BAJAS Y RELATIVAMENTE ALTAS. LA ESTRUCTURA ABSORBENTE OSMOTICA PUEDE INCLUIR SUPERABSORBENTES Y SE APLICA PREFERENTEMENTE A LAS SECCIONES DE BAJA DENSIDAD DEL SUSTRATO. PREFERIBLEMENTE LAS SECCIONES DE BAJA DENSIDAD SON DISTINTAS, DE MANERA QUE UNA RED DE ALTA DENSIDAD ESENCIALMENTE CONTINUA SE ENCUENTRA PRESENTE ENTRE LAS SECCIONES DE BAJA DENSIDAD. ESTE MONTAJE PROPORCIONA UNA MEJOR CAPTACION DE LIQUIDOS SIN EL BLOQUEO DE GEL. LA ESTRUCTURA ABSORBENTE ES UTIL PARA EL USO EN NUCLEOS DE ARTICULOS ABSORBENTES DESECHABLES.
