Abstract

The present invention provides an absorbent product, such as disposable diapers, incontinent pads, sanitary napkins that has an absorbent core that comprises synthetic fibers and super absorbent particulates in the size range less than 100 microns; what we define as SAP Powder. The absorbent core contains about 30 to 100 percent of the super absorbent particulate with a mass median particle size in the range of about 1 micron to about 100 microns.
