The reactivities of shark, pig, and bovine skin collagen fibers (abbreviated as SC, PC, and BC, respectively) with formaldehyde and basic chromium sulfate were investigated from the viewpoint of their binding potency and the tanning effects (thermal stability). The denaturation temperature (Td) of SC was lower than those of PC and BC, but the rise in Td (Δ To)by the treatment with formaldehyde was larger than those of PC and BC. Combined formaldehyde was greater than those of PC and BC. It is concluded that formaldehyde has a specifically effective tanning action on SC and the swelling in the initial stage is one of the most important factors in formaldehyde treatment of shark. In the treatment of basic chromium sulfate, the chromium adsorption of SC and PC was obviously inhibited by the addition of sodium chloride. The Td changes of SC and PC were affected by sodium chloride in the initial stage of the reaction, but it did not show remarkable influence on Td in the over-all reaction. Especially, the remarkable difference was not found in the process of Td rising between SC and PC. The Δ To of SC was small in chrome tanning, but it was increased by further processing like neutralization and drying, and eventually the difference between To of SC and PC became small. It is concluded that SC has a distinct reactivity with two different types of agents such as formaldehyde and basic chromium sulfate compared with PC and BC.
