Abstract
A fiber-SAP particle includes a superabsorbent core particle (SAP core particle) and a plurality of fibers attached to the SAP core particle and extending therefrom. The fiber-SAP particles may be formed in a fluidized bed chamber using a spray drying process. The fiber-SAP particles may be incorporated into absorbent cores and articles, such as in disposable diapers.
Claims26
A method of forming fiber-SAP particles, comprising mixing fibers with superabsorbent particles (SAP) such that at least some of the fibers attach to at least some of the SAP, thereby forming fiber-SAP particles, wherein said mixing is preceded by providing wetted fibers and introducing said wetted fibers with said SAP, and each fiber-SAP particle comprises a plurality of the fibers attached to one of the superabsorbent particles.
A method of forming fiber-SAP particles, comprising:
- providing wetted fibers, including providing said fibers in a liquid suspension;
- mixing said wetted fibers with superabsorbent particles (SAP) such that at least some of the fibers attach to at least some of the SAP, thereby forming fiber-SAP particles.
A method of forming fiber-SAP particles, comprising:
- forming an aerosol of a liquid suspension, the liquid suspension including wetted fibers;
- mixing said wetted fibers with superabsorbent particles (SAP) such that at least some of the fibers attach to at least some of the SAP. thereby forming fiber-SAP particles.
