Abstract

|
|
For the application of silk sericin, silk sericin powders were prepared by various spray dry conditions and the characteristics of sericin/polyurethane mixed films were investigated. When the sericin was dried from the solution at higher inlet and outlet temperature, larger sizes of the powder particles were obtained. It was also fuund that inlet and outlet temperatures were important factors affecting the shape and surface characteristics of sericin powder particle. The many holes and empty spaces were observed at the surface and crosssection of sericin/PU mixed film. With the increase of the amount of sericin powder in the mixed films, the size and number of holes and empty spaces were increased. The thickness of sericin/PU mixed film was increased with the content of sericin powder. As the portion of sericin powder increase, the tenacity is decreased while the elongation slightly increased.
