Abstract: An ink absorption member is provided which effectively prevents ink leakage from occurring even when the container storing the ink absorption member falls over. An ink absorption member is to be used to absorb ink. The ink absorption member includes a water-absorbent resin. In a mixture in which an ink is added to the ink absorption member in a ratio of 12 g of the ink to 0.24 g of the ink absorption member, the mixture has a viscosity of 5 Pa·s or greater and 100 Pa·s or less as measured 25 minutes after preparation of the mixture by using a tuning fork vibro viscometer. It is preferable that the water-absorbent resin be in the form of particles or a fiber.

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: A sheet manufacturing apparatus includes a defibrator configured to produce defibrated material, a feedstock supply unit, a monitoring device, and a cleaning device. The feedstock supply unit includes a conveyance device configured to convey feedstock, a storage device configured to accumulate the feedstock conveyed from the conveyance device and supply the feedstock to the defibrator, and a measuring device configured to measure a state of the feedstock accumulated on the storage device. The monitoring device is configured to predict stopping of conveyance of the feedstock by the feedstock supply unit and activate the cleaning device when a conveyance speed of the feedstock by the feedstock supply unit becomes slower than during normal operation. The cleaning device is configured to execute on at least one of the conveyance device and the storage device a cleaning process that preemptively prevents the stopping of conveyance.

Abstract: A sheet manufacturing apparatus can determine if the sheets supplied as feedstock have already been recycled. The sheet manufacturing apparatus has a supply unit configured to supply feedstock; a defibrating unit configured to defibrate the feedstock; an depositing unit configured to deposit defibrated material defibrated by the defibrating unit; a forming unit configured to form a sheet from a web laid by the depositing unit; a marking unit configured to apply a mark to at least one of the web and the sheet; and a reading unit configured to read the mark imparted to the feedstock when a sheet having mark imparted thereto is supplied as the feedstock.
