ABSTRACT:
A method for cutting fibrous materials using ultrasonic energy involves chemically modifying a fibrous material prior to the application of ultrasonic energy. Preferred fibrous materials include cellulose materials and its derivatives, such as, paper. Chemical modification includes oxidation or hydrolysis. Also disclosed is a test device made according to the method. The invention allows for the fusing of plastic and the simultaneous cutting of a chemically modified fibrous material along the line of fusion.
