PROBLEM TO BE SOLVED: To obtain a fiber formed body excellent in oxidative heat-generation resistance. SOLUTION: This fiber formed body is produced by binding inorganic fibers with polypropylene fibers consisting of a propylene composition obtained by compounding 100 pts.wt. of polypropylene with tris(4-t-butyl-3-hydroxy-2,6- dimethylbenzyl) isocyanurate and pentaerythritol tetrakis(3-alkylthiopropionate) each in 0.01-1 pt.wt. |
