Abstract
Provided is an absorbent article having excellent shape retention of an absorber even when an external force is applied thereto. The present invention is an absorbent article having: an aqueous-liquid absorbing part having crosslinked polymer particles having as essential constitutional units thereof a water-soluble vinyl monomer and/or a vinyl monomer which became the water-soluble vinyl monomer by hydrolysis, and a crosslinking agent; and a nonwoven fabric having porous fibers as an essential constituent thereof, the crosslinked polymer particles preferably absorbing 40 times the weight thereof of physiological saline 40 in 40-150 seconds.
Claims14
An absorbent article comprising:
- an aqueous-liquid absorbing part that contains crosslinked polymer particles (A) comprising a water-soluble vinyl monomer (a1) and/or a vinyl monomer (a2) that turns into a water-soluble vinyl monomer (a1) through hydrolysis, and a crosslinking agent (a3) as essential constitutional units;
- and
- a nonwoven fabric (B) comprising porous fibers (b1) as an essential constituent.
