Abstract

L’invention concerne un cœur absorbant et un procédé de fabrication d’un cœur absorbant destiné à une utilisation dans divers articles absorbants comprenant une couche supérieure, une couche inférieure et un cœur absorbant situé entre au moins des parties de la couche supérieure et de la couche inférieure. Le cœur absorbant comprend un matériau constituant une barrière contre les fluides en forme de C entourant au moins la surface faisant face à la couche inférieure et les côtés du cœur absorbant. Une ou plusieurs couches d’acquisition des fluides peuvent se trouver sur le cœur absorbant, entre ce dernier et la couche supérieure. Une ou plusieurs couches de gestion des fluides peuvent également se trouver dans le cœur.
