TITLE OF THE INVENTION: SHAPED ARTICLE OF COLLAGEN AND PROCESS FOR PREPARING SAME ABSTRACT OF THE DISCLOSURE: A shaped article of collagen having 5 to 20 µm of thickness, the peak maximum temperature of endothermic denatura- tion thereof being in the range of 62 to 71°C, the wet tensile strength thereof being in the range of 3 to 6 kg/mm2 and the wet tear strength thereof being in the range of 25 to 150 g cm/cm is prepared by a process comprising cross-linking a collagenous material so that the difference of the peak maximum temperatures of endothermic denaturation of the material between before and after the cross-linking falls in the range of 1.0 to 10°C and the peak maximum temperature after the cross-linking falls in the range of 63 to 74°C, fibrating the cross-linked collagenous material to prepare an aqueous dispersion with the viscosity of 100 to 2000 of and the spinnability of 30 to 80 mm at the concentration of 1% by weight of collagen fiber and subjecting the dispersion to electrodeposition.
