Spunbonded nonwoven webs having excellent properties, particularly softness, can be made from linear low density polyethylene having a critical combination of certain key properties. These properties are percent crystallinity, cone die melt flow, die swell, relation of die swell to melt index, and polymer uniformity. The polyethylene is extruded through a spinneret at a temperature between about 185°and 215°C. and drawn through an air gun to form the spunbonded web.

In the method of forming a spunbonded nonwoven web of continuous polyolefin filaments by extruding the polyolefin at a temperature above its melting point through a spinneret to form filaments of the polyolefin, drawing the filaments with an air gun, and depositing the filaments on a web-forming surface to form the nonwoven web, the improvement wherein the polyolefin is a linear copolymer of ethylene and an ethylenically unsaturated alpha-olefin having 4 to 8 carbon atoms, the copolymer having a percent crystallinity of at least 33 percent, a cone die melt flow of between about 65 and 85 grams/ten minutes, and a ratio of the natural logarithm of die swell to melt index of between about 0.014 and 0.020, and wherein the copolymer is extruded at a temperature between about 185°and 215°C.
