Aiming to obtain an interpretation of the cause for variance in behaviours between fish skin and terrestial animal hide, the relation between hydroxyproline content in the collagen and shrinkage temperatur (Ts) of different animal skins was determined.
As a result, it has proved that there was a direct proportion between hydroxyproline content in the collagen and Ts of different animal skins (sample correlation coefficient=0.93). For this reason, hydroxyproline seems to play an important part in the difference in behaviours between fish skin and terrestial animal hide
