Abstract

Using artificially bred sturgeon skin as the raw material, the character of the skin’s organizational structure was researched. In order to keep the integrity of its natural and special scale structure and also to enhance the removal of melanin on the grain surface as well as the fat inside the skin, various techniques like mechanical strength reduction, oxidation-reduction bleach, multi-procedure degreasing and manual fleshing etc. were adopted during the tanning procedure. A set of mature and feasible tanning process for sturgeon skin was obtained. The softness and fullness as well as the physical mechanical performance of the finished leather made by the process are good, and it would be a good choice for the high-end bags.
