Lyocell filament fiber and tire cord including the same are provided to manufacture tire cord having superior durability, shape stability and excellent abrasion resistance. Resistance of the lyocell filament fiber is 70% or more after finishing a repetitive abrasion test based on 1.0 g/d of load according to an ASTM D3412 method. An elongation maintenance rate is 70 - 100% after finishing the abrasion test of the fiber. Before the abrasion test, the elongation maintenance rate of the fiber is 7 - 15%, intensity of the fiber is 6 - 8g/d. The number of the abrasion test is 1000 time or greater. A tire includes a tread(1), a shoulder(2), a side wall(3), a cap ply(4), a belt(5), a body ply(6), and an inner liner(7) etc. |
