Abstract

【課題】強度に優れ、長期間の排水処理に適用可能な網状接触体要素の製造方法を提供すること。 【解決手段】合成繊維糸を立体網状になるように構成し、繊維糸の交点を接着してなる合成樹脂繊維ブロックを加工して回転円形網状接触体要素４を製造する方法において、前記合成樹脂繊維ブロックを、扇形形状をなすように切断して網状接触体要素前躯体を作製する工程と、前記扇形形状の網状接触体要素前躯体に、貫通孔２０を形成する工程と、前記網状接触体要素前躯体の外周２１及び前記貫通孔２０の周囲を圧縮して圧縮部２５を形成する工程と、前記網状接触体要素前躯体の外周２１及び前記貫通孔２０の周囲以外の全面２２を、９０°C～１４０°Cの温度下で空間率が９０％以上９８％以下になるように熱加圧処理する工程と、前記熱加圧処理工程後に、５日間以上の静止期間を設けて前記合成繊維の結晶化を促進する工程とを有することを特徴とする。
