Competency of Acacia mearnsii Tannin Extract for Vegetable Tanning Using Ultrasound Technique

This article describes the potential of Acacia mearnsii tannin extract for environmentally friendly vegetable tanning of leather using ultrasound. Vegetable tanning is a versatile but time-consuming process in the leather industry, particularly for heavy leather which needs more than one week for tanning using natural tanning materials. So, it is significant to develop new eco-friendly techniques employing ultrasound to speed up the vegetable tanning process without affecting the quality of the finished leather. In this study, the effect of ultrasound in vegetable tanning has been evaluated to enhance the tanning process. The effects of various parameters for example tannin dose, tanning time, temperature, and variable frequencies were studied. Tannin uptakes and other thermal properties were also investigated.
