A method of utilizing microwave energy in the manufacture of disposable nonwoven absorbent articles such as diapers and feminine care products. More specifically, the traditional hot melt adhesives utilized in the production of disposable nonwoven absorbent articles are replaced by adhesives that are microwave sensitive, and which can be activated by microwave energy to provide strong bonds for the finished article.
