Abstract
A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.
Claims22
1-20. (canceled)
A method of manufacturing a composite sheet, comprising the steps of
- positioning a first fabric to receive particles;
- positioning particles on the first fabric;
- securing the particles relative to said first fabric;
- positioning a second fabric over the particles;
- and
- forming bond sites that join said first fabric to said second fabric.
22-52. (canceled)
A disposable absorbent article comprising;
- a topsheet;
- a backsheet;
- and
- an absorbent core disposed between said topsheet and said backsheet, said absorbent core comprising:
- a first fabric;
- a second fabric;
- bond sites at which said first fabric is connected to said second fabric;
- and
- an absorbent layer of particles disposed between said first and second fabric.
An absorbent composite comprising,
- a first fabric;
- a second fabric bonded to said first fabric;
- and
- an effective concentration of particles disposed between the first and second fabric.
