Abstract
A method of making a composite material having elasticized portions includes supplying a web of temperature sensitive elastic material, applying a microwave sensitive material to selected regions of the elastic material and subsecting the composite material to microwave energy. The microwave energy may be converted into heat by the microwave sensitive material thereby heating the microwave sensitive material and activating regions of the temperature sensitive elastic material adjacent the microwave sensitive material. The activated regions of the elastic material provide the elasticized portions in the composite material. Alternatively, the microwave sensitive material may reflect the microwave energy which may then directly heat and activate the regions of the elastic material opposite the selected regions to which the microwave sensitive material is applied. The method is particularly useful in the manufacture of garment-type articles such as disposable absorbent articles.
