摘要:
An elastic laminate capable of being rolled for storage and unwound from a roll when needed for use, includes an elastic layer selected from the group consisting of an array of continuous filament strands, an array of continuous filament strands with meltblown deposited on the continuous filament strands, and a film; a gatherable facing layer bonded to only one side of the elastic layer; and either an adhesive that demonstrates a relatively short open time deposited between the elastic layer and facing layer, or such adhesive and a postbonding adhesive or nonblocking agent, or a nonblocking agent layer deposited on the elastic layer on a side opposite to the facing layer.
摘要:
An elastic laminate capable of being rolled for storage and unwound from a roll when needed for use, includes an external elastic film layer including a core layer and a first skin layer, and a necked facing layer thermally bonded to the first skin layer. In one aspect, the first skin layer has a softening point between about 40° C. about 125° C. In another aspect, the film skin layers may include an elastic polyolefin-based polymer having a degree of crystallinity between about 3% and about 40%.
摘要:
Absorbent articles having form fitting properties are disclosed. In particular, the absorbent articles include at least one waist elastic member that extends a substantial distance in the longitudinal direction. The waist elastic member, for instance, may be positioned in a front region of the article, in a back region of the article or in both the front and back regions. The waist elastic member comprises a breathable elastic film. In order for the film to be breathable, the film includes apertures. The apertures appear on the film according to a particular pattern and having a particular diameter so that the film retains desired stretch properties.
摘要:
A method for forming either an extensible or elastic laminate includes the steps of providing an elastic layer; and extruding at least one extensible meltblown web directly upon a first surface of the elastic layer to form an elastic layer and nonwoven laminate without the use of a separate adhesive.
摘要:
An elastomeric composite web (20) includes an elastomeric-substrate (22), and an operative layer of an elastomeric polypropylene-based adhesive material (24) or other surface modifying agent which is adhered or otherwise applied directly to at least one major, facing-side (26) of the elastomeric-substrate (22). In particular aspects, the layer of the surface modifying agent (24) has been provided separate from the elastomeric-substrate (22), and the layer of surface modifying agent (24) has been applied directly to the elastomeric-substrate (22) while the elastomeric-substrate has been operatively configured in a substantially unstretched condition. In other aspects, the elastomeric-substrate (22) can have a distinctively high basis weight, and the layer of surface modifying agent (24) can be applied directly to the elastomeric-substrate (22) prior to attaching the elastomeric-substrate to any separately provided, substantially non-elastomeric, supplemental-substrate. In a further aspect, the elastomeric-substrate (22) can be substantially free of continuous, elastomeric strands.

摘要:
A method for classifying errors in the layout of a semiconductor circuit includes examining the layout of the semiconductor circuit for infringement of predetermined design rules in order to establish errors. For each error, the error is marked in the layout, and information about the error and the layout of the semiconductor circuit in an area surrounding the error is extracted. The extracted information is compared with prestored information within a multiplicity of classes, and the error is assigned to the respective class on the basis of the compared information.
