Abstract
Fibers made a polyethylene composition, and method of making the same. The polyethylene composition comprises less than or equal to 100 percent by weight of the units derived from ethylene and less than 20 percent by weight of units derived from one or more α-olefin comonomers; wherein said polyethylene composition has a density in the range of 0.930 to 0.960 g/cm, a molecular weight distribution (Mw/Mn) in the range of 1.70 to 3.5, a melt index (I) in the range of 1 to 300 g/10 minutes, a molecular weight distribution (Mz/Mw) in the range of less than 2.5, a shear viscosity in the range of 20 to 250 Pascal-s at 3000 sshear rate measured at 190° C., vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of said composition; and wherein the fiber is a monocomponent meltspun fiber.
