White filature silk, also known as mulberry silk, is a type of silk and a high-grade variety of mulberry silk. It is a continuous long fiber formed by the solidification of the silk liquid secreted by silkworms when spinning cocoons. Before processing, it is called "raw silk," which has a slightly stiff texture and is semi-transparent. After refining and degumming, it becomes soft and glossy, at which point it is referred to as "boiled silk."
