Document Type and Number:

WIPO Patent Application WO/2016/104784

Kind Code:

A1

Abstract:

Provided is a filter fiber which is formed from a hydrophobic polymer and has water wettability. The fiber is formed from a hydrophobic polymer and has multiple frill-like protrusions, wherein the cross section of the fiber is formed by (a) an oval part having an approximately oval shape, (b) multiple protrusions which extend on both sides from the oval part and each of which has a rounded tip and (c) grooves each of which is formed between adjacent two of the protrusions. A hydrophilic polymer is adhered onto the surface of the fiber, and water wettability of the surface of the fiber is maintained when a treatment with hot water is carried out at 95°C in 15 rounds.
