Abstract
Superabsorbent polymer particles are used in a liquid-absorbent core of a disposable body fluid absorbent garment. The polymer particles include first polymer particles having a relatively high water-absorption speed and second polymer particles having a water-absorption speed longer than that of the first polymer particles by 10 seconds or more. The second polymer particles are integrally bonded to the first polymer particles.
