Abstract
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/m, preferably at least 230 kg/m, 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.
