Method of manufacturing cushion material

摘要

A method of manufacturing a cushion material for seat pads comprises a step for filling a mold part that will form the cushion material with a mixed fiber containing a thermofusible fiber, a step for engaging this mold part with another mold part, and a step for applying heat to a specific region of the mixed fiber that will form a bottom surface so that the thermofusible fiber in the specific region melts before the thermofusible fiber in the other region of the mixed fiber that will form a sitting surface of the cushion material.
