Abstract
A method for producing a seat cushion includes a molten filament supplying step of discharging a plurality of molten filaments of a thermoplastic resin or the like downward in a thermal vertical direction from a plurality of nozzle holes, a three-dimensional filaments fused body forming step of fusion-bonding contact points between the plurality of molten filaments while three-dimensionally entangling the molten filaments to form a three-dimensional filaments fused body, and a three-dimensional filaments-linked structure forming step of cooling and solidifying the three-dimensional filaments fused body while drawing the three-dimensional filaments fused body with an underwater drawing machine provided in cooling water to thereby form a three-dimensional filaments-linked structure, the three-dimensional filaments-linked structure forming step includes a three-dimensional filaments-linked structure density controlling step of controlling a density of the three-dimensional filaments fused body by varying a drawing speed of the underwater drawing machine.
