Method for manufacturing a bulk structure using plant fiber pulp and bulk structure manufactured by the same

The present invention relates to a method of manufacturing a bulk structure using plant fiber pulp and a bulk structure produced thereby， more specifically， by bulking the surface structure of the structure produced through wet molding of a pulp raw material made of plant fibers. The present invention relates to a method for manufacturing a bulk structure using plant fiber pulp， which greatly increases porosity， thereby significantly improving buffering and water absorption properties， and a bulk structure manufactured thereby. A method of manufacturing a bulk structure using plant fiber pulp according to the present invention comprises the steps of: (a) preparing a plant fiber pulp; (b) forming a sheet-like structure using the plant fiber pulp prepared in step (a); (c) adjusting the moisture of the structure formed in the step (b); And (d) forming voids and protrusions with a pointed tip member in the moisture-controlled structure in step (c).
