Abstract
A fiber that can exhibit both excellent antistatic properties and high water repellency, and a high bulk nonwoven fabric with a good texture that exhibits high water repellency. More specifically, a highly water repellent fiber that is a conjugate fiber having a plurality of thermoplastic resins as the primary component thereof and having a fiber treatment agent comprising at least Component (A) and Component (B) below deposited thereon at 0.1 to 1.0 wt % in relation to the weight of the fiber, with Component (A) accounting for 75 to 97 wt % and Component (B) accounting for 25 to 3 wt % of the fiber treatment agent: Component (A): polysiloxane Component (B): alkane sulfonate metal salt.
