Abstract
According to an embodiment, an apparatus for applying hydroxyapatite to a nonwoven fabric includes a tank, a shower head, an ultrasonic wave generator, and a drying section. The tank stores suspension containing hydroxyapatite. The shower head jets the suspension against the nonwoven fabric in the suspension in the tank. The ultrasonic wave generator emits ultrasonic waves against the nonwoven fabric. The drying section dries the nonwoven fabric in a wet state removed from the suspension in the tank.
