Liutuan silk refers to cocoon silk, that is, tussah silk, also known as Shandong silk or Lu silk. During the Jiaqing period of the Qing Dynasty, people from Liutuan, Changyi, Shandong, began to sell tussah silk, reel silk and weave silk in Dongshan (Tao Village, Qixia, Shandong). After Liutuan imported tussah cocoons from Dongshan, they gradually invented the reeling of tussah cocoons. During the Daoguang period, Liutuan people invented the wooden pedal reeling machine, and Liutuan silk was officially launched. In the continuous inheritance, the tussah silk reeling skills have been continuously improved, and gradually formed a complete set of processes: soaking silk, medicinal silk, reeling silk, reeling (reverse silk), pulling machine, brushing machine, collision shaft, silk machine, loom, bleaching, drying silk, and flat silk. Liutuan silk is finely woven, bright in color, comfortable to the touch, durable after grinding, warm in winter and cool in summer. China is the hometown of silk in the world, and Liutuan is one of the sources of the Silk Road. With its unique style of dense and glutinous texture and flowing elegance, Liutuan silk opened up the silk market in Southeast Asian countries in the 22nd year of Emperor Daoguang's reign (1842), opened up the Maritime Silk Road, and became a world-renowned silk town and hometown of overseas Chinese, leaving a glorious page in the history of cocoon and silk in China and the world.
