Abstract
A hydrophilic fiber comprising a thermoplastic resin, wherein 0.1-1.5% by weight of a fiber-finishing agent adheres to the fiber, the fiber-finishing agent containing 50-80% by weight of component A consisting of polyoxyethylene alkyl ether represented by the following general formula (1), 10-40% by weight of component B consisting of at least one quaternary ammonium phosphate salt selected from a group of salts represented by following general formulas (2) and (3), and 3-20% by weight of component C consisting of polyorganosiloxane represented by the following general formula (4).
