To realize favorable release properties and durability by a method wherein a fiber mat, which is made of coconut fibers mixed with a setting resin, is placed between metal plates, on each of which a polysiloxane is applied, for compression molding.
Coconut fibers are put in a hopper 5 while a setting resin is fed under pressure in a spray gun 7. Simultaneous with the movement of a belt conveyor 4, the coconut fibers are fallingly fed through respective hoppers 5 and entwined with each other by a needle punching device 6. Further, by jetting the setting resin from spray guns 7 and 7, a fiber mat 1 is produced. A polysiloxane coated on a metal plate 2 is most favorably used by diluting the emulsion type polysiloxane to 1-10% solution. The diluted polysiloxane is applied to the metal plates 2 with a sprayer or the like. The most preferable spread is 1-10g/m2 by solids content. Next, by placing the fiber mat 1 between the metal plates 2 of a hot press, a fiber board 3 is obtained, a fiber board 3 is obtained through a thermal compression molding.
