Nonwoven fabric with areas of differing basis weight

摘要

A spunbond nonwoven fabric is provided from a multiplicity of substantially continuous filaments which form a web having a length dimension and a width dimension. The filaments are arranged to define a substantially uniform web basis weight along one of dimension of the fabric, while in the other dimension, the filaments are arranged to define adjacent zones of a relatively lower web basis weight and a relatively higher web basis weight which is at least 25 weight percent greater than the basis weight of the lower basis weight zone. The spunbond nonwoven fabric can be combined with one or more additional layer to form a composite nonwoven fabric. The fabric is useful in various articles that utilize nonwovens, such as diapers, protective clothing, and hygiene articles.
