Abstract: A liquid absorber includes a container and an absorbing unit. The container has an opening and collects a liquid. The absorbing unit is an assembly of porous absorbent blocks, each containing fibers and a polymeric absorbent, and is in the container with spaces between the porous absorbent blocks. Each of the porous absorbent blocks has a first component and a second component. The first component is porous and has a density of 0.05 [g/cm3] or more and 0.50 [g/cm3] or less. The second component has a higher polymeric absorbent content than the first component.

Abstract: A liquid absorber includes a first liquid absorption member, a second liquid absorption member, and a case in which the first liquid absorption member and the second liquid absorption member are stored. The first liquid absorption member absorbs a portion of a liquid. The second liquid absorption member absorbs a portion of the liquid. A penetration property of the first liquid absorption member with respect to the liquid is greater than a penetration property of the second liquid absorption member with respect to the liquid. An absorption rate of the second liquid absorption member with respect to the liquid is greater than an absorption rate of the first liquid absorption member with respect to the liquid. When the liquid is introduced into the case, the liquid comes into contact with the first liquid absorption member before coming into contact with the second liquid absorption member.

Abstract: A liquid absorber includes a case, a first liquid absorption member stored in the case, and a second liquid absorption member stored in the case. The case has an opening. The first liquid absorption member absorbs a portion of a liquid. The second liquid absorption member absorbs a portion of the liquid. The second liquid absorption member is disposed adjacent to the first liquid absorption member and is closer to the opening than is the first liquid absorption member. The first liquid absorption member and the second liquid absorption member include fiber substrates and a liquid-absorbent resin, the liquid-absorbent resin being liquid-absorbent resin particles.

Abstract: A liquid absorber includes a liquid absorption member, a case, a cover member, and a filler member. The liquid absorption member absorbs at least a portion of a liquid. The liquid absorption member includes at least one of an assembly of fibers and an assembly of fiber substrates. The liquid absorption member is stored in the case. The cover member is coupled to the case. The filler member is disposed between the liquid absorption member and the cover member. The filler member is a member through which at least a portion of the liquid is to pass. A bulk density of the filler member is less than a bulk density of the liquid absorption member.

Abstract: A liquid absorber includes a plurality of small chips. Individual ones of the small chips include a first substrate containing fibers, a second substrate containing fibers, an absorbent resin supported between the first substrate and the second substrate, and an ion exchange resin supported between the first substrate and the second substrate. At least one of the absorbent resin and the ion exchange resin is exposed at an end face of the small chips.

Abstract: Provided are a binder useful for making sheets processed to effectively prevent misfeeds, a sheet manufacturing apparatus capable of desirably manufacturing sheets processed to effectively prevent misfeeds, a sheet manufacturing method, and a sheet processed to effectively prevent misfeeds. The binder for binding fiber to make sheets includes resin; and polyhydric alcohol that is a solid at room temperature and changes to liquid phase when heated. The content of polyhydric alcohol to 100 parts by weight resin is greater than or equal to 0.1 parts by weight and less than or equal to 20 parts by weight polyhydric alcohol.
