    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： An adhesive composition including an atactic polymer, an isotactic polymer, and an extensible base polymer, such as ethylene-vinyl acetate and/or ethylene methacrylate. The composition may also include a tackifier, such as a high softening point tackifier resin, a low softening point additive, and/or other additives, such as an antioxidizing agent, a plasticizer, mineral oil, color pigment, filler, polymer compatibilizer, or a combination of any of these additives. Facing layers, particularly stretchable and/or elastomeric substrates, can be bonded with the adhesive composition. The adhesive composition maintains high bond strength, even at body temperature and after initial stretching. Such adhesive compositions and laminates can be made according to a method of the invention.

    摘要： We have determined that strength characteristics of elastic strand improve when the strand is heated. Thus, the present invention is directed to improving strength characteristics of an elastic strand by heating the strand. The strand may be heated by thermal conduction and/or convection, by irradiative methods using, for example, infrared or microwave radiation, or some combination of these. If the elastic strand is made at a location different from the location where the strand is used as a raw material, the strand may be heated at either location, or both locations. Furthermore, the strand may be heated in-line, i.e. as part of the process that makes the strand or the process that uses the strand as a raw material, or off-line, i.e. in a step separate from either of the aforementioned processes. Finally, in addition to heat treating the strand, the strand's exposure to water or water vapor may be regulated to reduce or eliminate strength degradation.
