PROBLEM TO BE SOLVED: To provide a high-performance felt with high bladeproofness and abrasion resistance comprising high-tenacity polyethylene fibers of high uniformity with slight tenacity variation among the single filaments. SOLUTION: The felt is≥1.4 in apparent density, comprising high-tenacity polyethylene fibers≤9 nm in monoclinic-derived crystalline size, 0.8-1.2 in the size ratio of the orthorhombic crystal to the diffraction plane-derived crystal and≥20 cN/dtex in average tenacity.
