    • PROBLEM TO BE SOLVED: To provide a method for producing a flameproof fiber bundle capable of providing a carbon fiber bundle having few structural defects in a single fiber in a method for producing the carbon fiber bundle; and to provide the method for producing the carbon fiber bundle capable of achieving the stabilization of the strength at the production of the carbon fiber bundle, especially the stabilization of the strength at the start of the production.
      SOLUTION: The method for producing the flameproof fiber bundle by heating a polyacrylonitrile-based fiber bundle having a fiber fineness of 100-30,000 dtex and a number of filaments of 500-70,000 in a heat treating furnace in which an oxidizing gas is circulated in an oxidizing atmosphere at 200-300°C. The method includes: circulating the oxidizing gas through a filtering device which has a filter medium unit having an aggregate in which 97-100% by volume of ceramic particles or metal particles have a particle diameter of 2-80 mm, and packed in the interior thereof, and which is installed in the interior of the heat-treating furnace and/or the circulating duct part of the heat-treating furnace.

    • PROBLEM TO BE SOLVED: To provide a filter which improves the stabilization of a granulate filter medium without causing the excessive funnel effect of a wall surface.
      SOLUTION: The filter is provided with a hollow frame having a first surface, a second surface, and an inner passage between them, a first filter net crossing the passage at the first surface, a matrix which is a first partial depth stabilization member for an open cell extending inward across the passage and formed of a plurality of wall parts, a second filter net crossing the passage at the second surface, a matrix which is a second partial depth stabilization member for the open cell extending inward across the passage and formed of a plurality of wall parts, and the granulate filter medium densely filled into the passage. The sum of the depths of the first and second partial depth stabilization members for the open cell is smaller than the depth of the filter (the distance between the first filter net and the second filter net). The depths of the first and second stabilization members, the number, size, and cross section of the open cells, the depth of the filter, the composition of the granulate filter medium, and filling density are balanced with each other.
