Abstract
Organic fibers and inorganic fibers, used as materials, are mixed, thereby forming a web 18. Inter-fiber bonding is then performed on the web, forming a non-woven fabric web. The non-woven fabric web is cut, providing a web piece 18a shaped like a seat pad 30. The web piece is set in a metal mold and then compressed in the metal mold. Next, the metal mold is heated, thereby heating the organic fibers of the web piece, at surface, thereby welding the organic fibers together and molding a seat pad. The seat pad is covered with a trim cover, producing a cushion. The organic fibers are used in mixing ratio of 50% by weight or more, and the inorganic fibers are used in mixing ratio of 50% by weight or less. The organic fibers are made of simple high-molecular substance such as polyethylene fibers.
