FIBER BOARD AND METHOD FOR PRODUCING SAME

Provided are: a homogeneous fiber board which has small variation in weight per square meter; and a method of the same. The present fiber board (100) is obtained by: mixing a vegetable fiber (1) (such as kenaf fiber) and a thermoplastic resin fiber (such as polypropylene fiber) to form a web; forming a fiber mat by needle punch method or the like to interlace the fibers that constitute the web; and heating and compressing the fiber mat. The vegetable fiber is crimped in advance by stirring a raw material fiber in presence of water. The present production method has: a web-forming process wherein a web is formed by mixing a vegetable fiber and a thermoplastic resin fiber; a mat-forming process wherein a fiber mat is formed by interlacing the fibers that constitute the web; and a board-forming process wherein a fiber board is formed by compressing the fiber mat with heating.
