Abstract

La invención se refiere a un núcleo absorbente para usarse en un producto absorbente, tal como una toalla sanitaria, un pañal, una protección contra incontinencia o similares, el núcleo después de compresión teniendo una densidad de material (basado en el contenido total del núcleo) de por lo menos 200 kg/m3, preferiblemente por lo menos 230 kg/m3, medido a una presión de 0.5 kpa por lo que el núcleo absorbente se ha formado en línea como un núcleo discreto o continuo, caracterizado porque el núcleo absorbente comprende partículas de SAP, por lo que por lo menos 99.5% de las partículas de SAP tienen un tamaño máximo de 600 µm. Por lo tanto, los problemas con respecto a la obstrucción de partículas de SAP a rodillos de compresión durante la manufactura se reducen marcadamente. Además, la invención se refiere a un método para manufacturar el núcleo absorbente, así como un producto absorbente que comprende el núcleo absorbente.
