PURPOSE: To obtain an adsorbent which is easy to be formed, having excellent adsorbing properties and low pressure loss, and is usable for cleaing in a wide range, and to provided its manufacturing method.
CONSTITUTION: A fibrous absorbent is composed of composite fibers consisting of an aromatic monovinyl-type polymer A and a thermally plastic polymer B except for polymer A, and the aromatic monovinyl-type polymer A composing the fibers has fine pores and 0.1m2/g or more of specific surface area. The manufacturing method of the fibrous adsorbent involves mixing a water-soluble polymer C with the aromatic monovinyl-type polymer A, compounding and spinning the mixed polymer with the thermally plastic polymer B except for the polymer A, and removing at least a part of the water-soluble polymer C from the obtained composite fibers.
