An absorbent core for use in an absorbent product, such as a sanitary napkin, a diaper, an incontinence protection or the like. The core after compression has a material density (based on the total content of the core) of at least 200 kg/m3, preferably at least 230 kg/m3, measured at a pressure of 0.5 kPa. The absorbent core has been formed in-line as a discrete or continuous core and includes SAP-particles, where at least 99.5% of the SAP-particles have a size of maximally 600 μm. Hereby, problems with regard to clogging of SAP-particles to compression rollers during manufacturing are markedly reduced. Further, a method for manufacturing the absorbent core, as well as an absorbent product including the absorbent core is described.
An absorbent core for use in an absorbent product, the core after compression having a material density (based on the total content of the core) of at least 200 kg/m3, measured at a pressure of 0.5 kPa whereby the absorbent core has been formed in-line as a discrete or continuous core, wherein the absorbent core comprises three sub-layers, wherein a first sub-layer, viewed from a wearer-facing side of the core, primarily comprises pulp, the second sub-layer comprises SAP-particles and pulp, and the third sub-layer primarily comprises pulp, and the SAP-particles have a size smaller than 300 μm, thereby obtaining a minimised number of defect absorbent cores as a result of reduced clogging of the SAP-particles during manufacturing of the absorbent cores.
