Abstract:

A nonwoven web made from a polymeric fiber blend comprising at least one elastomeric polyolefin and at least one nonelastomeric polyolefin useful as the elastic base sheet for a nonwoven laminate is disclosed. Preferably, the polymeric blend will comprise a nonelastomeric resin in the range of from about 10 to about 90 percent by weight, and an elastomeric resin of from about 90 to about 10 percent by weight. The elastomeric polyolefin will have a density of less than about 0.885 g/cmand the nonelastomeric polyolefin will have a density of at least about 0.890 g/cm. In one particular embodiment, the polymeric blend may comprise about 50 percent to about 90 percent by weight of a narrow molecular weight distribution polyethylene and about 50 percent to about 10 percent by weight of a nonelastomeric polyolefin such as a linear low density polyethylene.
