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.

Laminates of elastomeric and non-elastomeric polyolefin blend materials

Disclosed is a fibrous nonwoven structure comprising meltblown fibrous materials and at least one secondary fibrous material and method of preparing. In one aspect, the fibrous nonwoven structure has a formation index of between 70 and 135. In another aspect, the fibrous nonwoven structure has an opacity that is greater than 72 percent at a basis weight of between about 35 and 55 grams per square meter. The fibrous nonwoven substrate may be utilized as a moist wipe.

Fibrous nonwoven structure having improved physical characteristics and method of preparing

A method for increasing the thickness of a fibrous sheet including stretching the sheet beyond its relaxed length and returning the sheet to about the relaxed length, causing the sheet to have a second thickness greater than the first thickness. The sheet can be a wet-wipe. The wet-wipe includes an elastic layer and a fibrous layer, which increases in thickness when stretched then relaxed. The wet-wipe can be stored in a container which causes the wet-wipe to stretch as it is removed from the container.

Stretchable composite sheet for adding softness and texture

The present invention provides a wet-wipe comprising a non-woven composite elastic material comprising a non-woven elastic layer; and a non-woven gatherable layer. The gatherable layer is bonded to the elastic layer at at least two points; and is gathered between the bonded points. These wet-wipes have a softer more cloth like feel.

Composite material with cloth-like feel

The present invention provides a process for heat treatment of non-woven composite elastic material including a non-woven elastic layer; a non-woven gatherable layer. The process includes stretching the material, heating the material and cooling the material. The material has a softer more cloth-like feel.

Method for controlling retraction of composite materials

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/cm and 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.
