Abstract:
1. An absorber formed integrally by overlapping in layers with an upper water-absorbing paper layer portion comprised of an upper surface, a lower water-absorbing paper layer portion comprised of a lower surface, and a water-absorbing mixture layer portion provided between the upper water-absorbing paper layer portion and the lower water-absorbing paper layer portion; wherein the water-absorbing mixture layer portion is comprised of a crushed pulp fiber material beaten to fiber length of 0.1 to 7 mm in content percentage of not more than 5 weight % of fine particle with particle size of less than 0.1 mm, crushed tea dregs having a particle size of 0.7 to 3.8 mm in mixing content percentage of 14 to 43% by weight, based on the crushed pulp fiber material as dry weight, and a water-absorbing resin in an amount less than the crushed pulp fiber material, and the particles of crushed tea dregs are distributed so that the content increases from upper to lower within the water-absorbing mixture layer portion, and an upper water-absorbing paper layer portion, a water absorbing mixture layer portion and a lower water-absorbing paper layer portion are press-shaped integrally by overlapping in layers, to contain crushed tea dregs and to have large infiltration velocity and large drying velocity.
