A high water-repellent fiber comprising a thermoplastic resin, wherein the following components (A) 75-90% by weight, (B) 5-20% by weight and (C) 1-5% by weight are adhered on the fiber 0.1-1.0% by weight per fiber: (A) a mixture comprising less than 55% by weight of at least one metal alkyl phosphate of 14-18 carbons, and 45% or more by weight of at least one metal alkyl phosphate of 20-24 carbons; (B) a compound containing a perfluoroalkyl group; and (C) a metal alkyl phosphate of 2-6 carbons. The fiber has excellent antistatic properties and water repellency, no troubles of static electricity are found in the step for processing fibers into nonwovens, so that the resulting nonwovens can be preferably used for leakage-preventing materials or impermeable sheets of hygienic materials. |
