Abstract
The structure of the silk sericin taken off from the liquid silk obtained by casting the liquid silk at different temperatures was studied by means of differential scanning calorimetry (DSC), density and X-ray diffraction. Thermal decomposition temperature of silk sericin cast above 0°C was ca. 250°C, while the specimen obtained by casting the liquid silk below 0°C showed two peaks in the decomposition temperature, namely ca. 220°C and 260°C. Density and endothermic amount of the specimen obtained by casting below 0°C increased. When the casting temperature decreased, the degree of crystallinity of the silk sericin reversely increased, but the crystal structure remained unchanged
