Title:
SEAT CUSHION, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/210220
Kind Code:
A1
Abstract:
This method for manufacturing a seat cushion comprises: a molten filament supply step for discharging a plurality of molten filaments formed of a thermoplastic resin or the like from a plurality of nozzle holes toward a lower side in the thermal-vertical direction; a filament three-dimensional fused body formation step for forming a filament three-dimensional fused body by fusion-bonding contact points between the molten filaments while three-dimensionally winding the plurality of molten filaments; and a filament three-dimensional bonded body forming step for forming a filament three-dimensional bonded body by cooling and solidifying the filament three-dimensional fused body while being drawn by an underwater drawing machine provided in cooling water, wherein the filament three-dimensional bonded body forming step includes a filament three-dimensional bonded body density control step for controlling the density of the filament three-dimensional fused body by changing the speed of the underwater drawing machine.
