Title:
ACTIVATED CARBON-CONTAINING CELLULOSE PARTICLE
Document Type and Number:
Japanese Patent JP2015136473
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an activated carbon-containing cellulose particle having an excellent deodorizing effect.SOLUTION: The activated carbon-containing cellulose particle is obtained by: depositing wood-based activated carbon on a skeleton, which comprises a cellulose fiber and a binder, to obtain an activated carbon-containing cellulose particle precursor; and impregnating the activated carbon-containing cellulose particle precursor with an organic solvent. The activated carbon-containing cellulose particle has 80 mass% or higher hardness when measured according to JIS K1474. The solubility parameter of the organic solvent is 9.0-14.0 (cal/cm). The wood-based activated carbon accounts for 48-77 mass% of the total mass of the activated carbon-containing cellulose particle and the organic solvent accounts for 8-25 mass% of the total mass thereof.
