Abstract

PROBLEM TO BE SOLVED: To prepare a fiber sheet light in weight, excellent in rigidity and suitable for interior finishing materials of automobiles, etc., without using glass fibers, which damage working environments, by heating a sheet made of specific mixed fibers to soften thermoplastic fibers in the mixed fibers and bond the mixed fibers. SOLUTION: A sheet 2 is made of mixed fibers composed of bamboo fibers and another plant fiber such as hemp fibers, etc., at a weight ratio of (70/30)-(30/70), and further mixing the resultant mixed plant fiber with thermoplastic fibers such as polyethylene fibers at a ratio of 30:70 wt.%. The obtained sheet 2 is heated to soften the thermoplastic fibers and bond the mixed fibers. Further, it is preferable that the sheet 2 made of the mixed fibers is produced by laminating a sheet on one side or on each of the both sides of the sheet 2 made of the mixed fibers, and subsequently heating the resultant laminate to soften the thermoplastic fibers and bond the laminate.
