<p>A polyethylene fiber of excellent incision resistance exhibiting an Mw, in fibrous form, of 300,000 or less, an Mw/Mn of 4.0 or below, a strength of 15 cN/dtex or greater and an elasticity of 500 cN/dtex or higher; and an incision resistant textile woven or knit fabric, fibrous material for reinforcement of cement mortar or concrete, or rope, constituted of the fiber. This fiber is produced by drawing an undrawn yarn of polyolefin whose Mw, Mw/Mn and birefringence ratio (Δn) are 60,000 - 600,000, 4.5 or below and 0.008 or higher, respectively at a temperature not higher than the crystal dispersion temperature of the undrawn yarn.</p> |
