Abstract

La présente invention concerne un composite réticulé absorbant comportant une couche centrale réticulée et une couche intermédiaire fibreuse. La couche centrale et la couche intermédiaire sont formés solidaires et la couche intermédiaire est accolée à une surface de la couche centrale. Dans un premier mode de réalisation, le composite comprend des couches intermédiaires sur les surfaces opposées de la couche centrale. La couche centrale comprend une matrice fibreuse et une matière absorbante. La matrice fibreuse définit des vides et des passages entre les vides, lesquels sont répartis dans tout le composite. Une matière absorbante est située à l'intérieur de certains des vides. Lors d'une humidification, la matière absorbante située dans ces vides s'étend à l'intérieur du vide. L'invention concerne également des procédés de formation du composite et d'articles absorbants contenant ce composite.
