Abstract
This paper is to study a new method to remove sericin from raw silk fiber. This new process is done using an organic acid as a pretreatment and then using CO2 supercritical fluid to remove sericin from silk fiber. This method would be a huge break from the traditional environmentally unsustainable methods used today. This new processing method keeps the removed sericin in a clean state that can be used as a highly marketable silk protein in the medical and cosmetic industries.
Highlights
Silk fibers are spun as a natural process of silk worms
Decorticated silk fiber (Bombyx Mori) used in these study was collected from Taipei city, Taiwan
Silk fiber is cut into 5 cm × 8 cm with a weight between 2 g to 4 g for super CO2 critical degumming test
Summary
Silk fibers are spun as a natural process of silk worms. Silk (Bombyx Mori) is one of the world’s most revered natural fibers used by the fashion industry. This is due to it having exceptional characteristics such as: long fine fibers, high tensile strength, a rich luster and numerous mechanical properties. Throughout history, silk has been valued greatly and has been used as the benchmark when creating synthetic fibers. Silk is known for its comfortable touch to the body, moisture regulation properties, staying cool in hot conditions, and excellent ventilation. Silks high-class luster has increased the fibers status in the fashion world
