Abstract
The instant invention discloses fibers. The fibers according to the instant invention comprise a polyethylene composition comprising: (a) less than or equal to 100 percent by weight of the units derived from ethylene; and (b) less than 20 percent by weight of units derived from one or more α-olefin comonomers; wherein the polyethylene composition has a density in the range of 0.920 to 0.970 g/cm3, a molecular weight distribution (Mw/Mn) in the range of 1.70 to 3.5, a melt index (I2) in the range of 0.2 to 1000 g/10 minutes, a molecular weight distribution (Mz/Mw) in the range of less than 2.5, vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of the composition.
