Abstract:
The present invention provides nonwoven webs comprising multicomponent fibers that enable the nonwoven web to possess high extensibility. The multicomponent fibers will comprise a first component comprising a polypropylene composition having a melt flow rate of from about 100 to about 2000 grams per 10 minutes and a second component comprising a polymer composition having a melt flow rate lower than the melt flow rate of the first component. The first component comprises at least about 10% of a surface of the multicomponent fiber.
