Liquid absorber, liquid tank, liquid droplet ejection device, and sound absorber

摘要

A liquid absorber that is constituted mainly by fibers, includes fusion bondable resin, and is configured to absorb liquid, includes a first surface having a largest surface area, and a second surface perpendicular to the first surface. The second surface includes a surface low in degree of fusion bond of the fusion bondable resin and a surface high in degree of fusion bond of the fusion bondable resin that has a higher degree of fusion bond of the fusion bondable resin than the surface low in degree of fusion bond, and at least a part of the surface low in degree of fusion bond absorbs the liquid.

1. A liquid absorber that is constituted mainly by fibers, includes fusion bondable resin, and is configured to absorb liquid, comprising:
a first surface having a largest surface area, wherein the first surface consists of a single plane; and a second surface perpendicular to the first surface, the second surface including a surface low in degree of fusion bond of the fusion bondable resin and a surface high in degree of fusion bond of the fusion bondable resin that has a higher degree of fusion bond of the fusion bondable resin than the surface low in degree of fusion bond, a boundary between the surface low in degree of fusion bond and the surface high in degree of fusion bond extending perpendicular to the first surface, at least a part of the surface low in degree of fusion bond absorbing the liquid.
