The invention discloses a novel fiberboard manufacturing process. The novel fiberboard manufacturing process is characterized in that a fiberboard comprises a middle layer, and the middle layer is externally provided with a surface chemical fiber layer and is a composite layer made of coconut fiber and chemical fiber; the fiberboard manufacturing process comprises the following steps of S1, raw material preparation, S2, raw material storage, S3, primary middle layer raw material mixing, S4, primary middle layer raw material carding, S5, secondary middle layer raw material mixing, S6, secondary middle layer raw material carding, S7, surface-layer chemical fiber raw material preparation, S8, surface-layer chemical fiber net paving, S9, surface-layer chemical fiber needling, S10, semi-finished product synthesis, S11, drying machining, S12, cooling shaping, and S13, finished product completion. According to the novel fiberboard manufacturing process, the natural coconut fiber and the chemical fiber are composited, the produced fiberboard is of a three-layer structure, and the coconut fiber is covered with the chemical fiber, so that the fiberboard is more beautiful, and the toughness of the fiberboard is improved; and fiber on the surface layer is subjected to needling treatment, the strength of the fiberboard is improved, and thus, the fiberboard is not prone to being abraded.
