Abstract: A rotary-wing shaped fiber filter material includes a fiber bundle (1) composed of fibers and a rotary-wing core (2). The fiber bundle (1) perforates through the center of the rotary-wing core (2) by injection moulding and consolidates. A fiber joint (3) is set on the fiber bundle (1) and located at the position where the fiber bundle (1) and the rotary-wing core (2) consolidate. The fiber joint (3) can be a joint formed by knotting the fibers, a joint where the fibers intersect, a joint where the fibers fold, or a joint where a fiber binds other fibers.
