Abstract: An ultrasonically bonded fabric package for a vaporizable anti-static softening bar to be employed in an automatic dryer. To fabricate the package the bar is placed on a sheet of fabric consisting of approximately 60 to 70% Dacron and 30 to 40% cotton and the sheet is folded over to enclose the bar. The three open sides of the folded fabric are bonded together by applying pressure to the side edges in an amount of 20 to 40 psi, while subjecting the fabric to ultrasonic vibrations. A thermoplastic Velcro hook strip is bonded to the outer surface of the fabric envelope. The hook strip is adapted to engage a Velcro loop strip secured to the internal surface of the automatic dryer.
