EFFECTS OF CHROME-TANNING PROCESS ON STRUCTURAL CHARACTERISTICS AND PHYSICO-MECHANICAL PROPERTIES OF CROCODYLUS POROSUS LEATHER

Abstract

Crocodile leather occupied about 80% of the crocodile's value, and has high economic value. Due to the different in the structure and texture of the crocodile leather, each fashion products made from it is highly unique. Because the crocodile leather could be easily damaged during the breeding, harvest and production process, the leather must be tanned to improve the durability and practicability of leather products and prevent putrefaction. This research will consider the change in color, surface patterns, structures and physic-mechanical properties of the different leather parts. The leather part has been investigated before and after the tanning process with a chromium salt. In this research, 2 years old Crocodylus porosus crocodile was studied.
