SOFT EXTENSIBLE NONWOVEN WEB CONTAINING MULTICOMPONENT FIBERS WITH HIGH MELT FLOW RATE

摘要

PROBLEM TO BE SOLVED: To respond to such a problem that there exists within the industry a need for extensible nonwovens made of moderate- to low-denier fibers that can be made from conventional resins without the need for high cost specialty polymers or elastic polymers.

SOLUTION: There is provided 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 2,000 g/10 min 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.
