Abstract

EN LA PRESENTE INVENCION SE PRESENTA UN ARTICULO ABSORBENTE QUE INCLUYE UNA CAPA SUPERIOR PERMEABLE A LOS FLUIDOS, UNA CAPA POSTERIOR IMPERMEABLE A LOS FLUIDOS UNIDA A LA CAPA SUPERIOR Y UNA CAPA INTERMEDIA COLOCADA ENTRE LA CAPA SUPERIOR Y LA CAPA POSTERIOR. LA CAPA SUPERIOR COMPRENDE: UNA MALLA ELASTICA, TRIDIMENSIONAL, MACROSCOPICAMENTE EXPANDIDA, PERMEABLE A LOS FLUIDOS (10) QUE INCLUYE UN PRIMER MATERIAL POLIMERICO (50) QUE PRESENTA UNA PRIMERA TEMPERATURA DE PUNTO DE FUSION Y UN SEGUNDO MATERIAL POLIMERICO (52) UNIDO AL PRIMER MATERIAL POLIMERICO PARA FORMAR UNA ESTRUCTURA LAMINADA. EL SEGUNDO MATERIAL POLIMERICO PRESENTA UNA SEGUNDA TEMPERATURA DE PUNTO DE FUSION QUE ES MENOR QUE LA PRIMERA TEMPERATURA DE PUNTO DE FUSION. LA MALLA TIENE UNA PRIMERA Y SEGUNDA SUPERFICIES (41, 43) SEPARADAS UNA DISTANCIA MAYOR QUE EL GROSOR DE LA ESTRUCTURA LAMINAR. LA MALLA INCLUYE UNA PLURALIDAD DE CAPILARES (40) QUE SE EXTIENDEN DESDE LA PRIMERA SUPERFICIE HASTA LA SEGUNDA SUPERFICIE. LOS CAPILARESQUEDAN DEFINIDOS POR UNA PLURALIDAD DE PORCIONES DE PAREDES LATERALES (55) INTERCONECTADAS ENTRE SI ENTRE MEDIAS DE LA PRIMERA Y LA SEGUNDA SUPERFICIES Y QUE TERMINAN EN LA SEGUNDA SUPERFICIE DE MODO QUE CUANDO LA MALLA SE CALIENTA A UNA TEMPERATURA ENTRE LA PRIMERA TEMPERATURA DE PUNTO DE FUSION Y LA SEGUNDA TEMPERATURA DE PUNTO DE FUSION, EL MATERIAL POLIMERICO DE LA PARED LATERAL SE UNE TERMICAMENTE A LA CAPA INTERMEDIA (61, 201, 305) A LO LARGO DE LA SEGUNDA SUPERFICIE DE LA MALLA.
