Application of power ultrasound (18kHz-1MHz) to leather processing has become more viable due to (1) increased commercial availability and advances of ultrasound technology, (2) the apparent applicability of ultrasound across the whole breadth of "wet" processes in leather manufacturing, and (3) tightened environmental legislation which demands new efficient process- ingtechnology. Thus power ultrasound (38 kHz, 1.36 W cm~-2) has been employed in our systemat- ic investigations on a number of leather processes.
