PURPOSE:To efficiently manufacture a fiber cushion body having high durability and high quality in simple manufacturing processes. CONSTITUTION:Low-density fiber lumps 10 made of three-dimensionally entangled fibers are compressed to the preset thickness in a molding die 12, and fibers are bound together by binder fibers. Many low-density cotton ball-like fiber lumps 10 having the density of 1/4 or below of that of a molding are used to manufacture a cushion body, and manufacturing processes include the process to insert a present quantity of the low-density fiber lumps 10 into the molding die 12, the process to compress the fiber lumps 10 to the density of the molding, the process to melt and cool the binder fibers, bind the fibers together, and mold them into the preset shape, and the mold releasing process to extract the molding from the die 12. |
