Fibers made from polyethylene compositions, and method of making the same

A process for making a fiber comprising the steps of:

• selecting a polyethylene composition comprising 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/cm3, a molecular weight distribution (Mw/Mn) in the range of 1.70 to 3.5, a melt index (I2) 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 s−1 shear 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
• spinning said polyethylene composition into a fiber, thereby forming a monocomponent meltspun fiber, and wherein said fiber has an elongation measured in percent of less than 1000.

A fabric comprising:

• one or more monocomponent meltspun fibers having an elongation measured in percent of less than 1000, wherein the one or more monocomponent meltspun fibers are from a polyethylene composition comprising 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/cm3, a molecular weight distribution (Mw/Mn) in the range of 1.70 to 3.5, a melt index (I2) 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 s−1 shear 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.
