<p>Hydrophilic fibers having a durable hydrophilic property and excellent safety, and fabrics and filters both obtained by using the fibers are provided; the hydrophilic fibers are produced by adhering 0.1 to 1.0 % by weight, based on the weight of fiber, of a finishing agent comprising 20 to 90 % by weight of the following composition (A) and 10 to 80 % by weight of the following composition (B), to a fiber comprising one or more thermoplastic resins having a water absorption of 1 % by weight or lower: (A) a composition comprising 0 to 75 % by weight of at least one compound selected from the group consisting of sorbitan esters of a fatty acid having 12 to 18 carbon atoms and 25 to 100 % by weight of at least one compound selected from the group consisting of adducts of a sorbitan ester of a fatty acid having 12 to 18 carbon atoms with 5 to 20 mole of ethylene oxide; (B) at least one compound selected from the group consisting of (a) white mineral oils, (b) diesters of a fatty acid having 12 to 18 carbon atoms with a polyethylene glycol having a molecular weight of 200 to 600, (c) diesters of a fatty acid having 12 to 18 carbon atoms with a polypropylene glycol having a molecular weight of 200 to 600, (d) pluronic type nonionic surface active agents, and (e) metal salts of an alkyl sulfonate having 8 to 16 carbon atoms.</p> |
