Abstract
The present invention relates to an elastic nonwoven fabric comprising a nonwoven web that is made of a plurality of fibers, which fibers are bicomponent fibers which each comprise a first component and a second component, wherein the first component is present in an amount in the range of from 80-95% by weight and the second component is present in an amount in the range of from 5-20% by weight, both weights based on the total weight of each fiber; wherein the first component comprises an ethylene/α-olefin copolymer and the second component comprises a low density polyethylene having a density in the range of from 0.90-0.95 g/cm3 (as determined with ASTM D792); wherein the first component and the second component both have a melt flow rate in the range of from 10-40 g/10 min (as determined by ASTM D1238 (190° C., 2.16 kg)); and wherein the nonwoven web comprises a side which is provided with a pattern of individualized bonded areas, wherein the surface of the bonded areas is in the range of 8-25%, based on the total surface of the side. The present invention further relates to a process for preparing the nonwoven fabric, and an article comprising the nonwoven fabric.
