Abstract:

The present invention is a separation device that separates a liquid-absorbent fiber from a material having contaminants and the liquid-absorbent fiber, which pertains to an absorbent article. The present invention has: a case; a partition member that compartmentalizes the interior space of the case into a first space and a second space; an introduction opening through which the material is introduced into the first space while riding on a flow of air; a rotating member that is housed in the first space and that agitates and opens the material; and a discharge opening that, of the material opened by the rotating member, causes the discharge from the interior of the first space of the liquid-absorbent fiber while riding on a flow of air. The partition member has a plurality of through holes that interconnect the first space and the second space. The second space is provided with an air intake opening that aspirates air within the second space, and the air intake opening aspirates the liquid-absorbent fiber that has passed through the through holes of the partition member and is floating within the second space.
