Silk Spinning Machineries of Faculty of Textile Science and Technology, Shinshu University

Silk spinning is a technique for spinning long fiber. Silk spinning in Japan began in 1877 with the founding of the government-operated Shinmachi Waste Spinning Mill. The silk-spinning industry is considered a secondary industry to sericulture (sericulture and silk spinning) and has developed simultaneously with the sericulture industry, since silk spinning is produced from the by-product of the cocoon and raw-silk production process (such as silkworm waste, spun silk, and discarded cocoons).
The silk-spinning machines (manufactured by Greenwood & Batley Ltd.) imported from England and installed for the silk-spinning training of the silk-spinning department of the government-operated Ueda Silk Technical School (currently Shinshu University Faculty of Textile Science and Technology), which opened in 1913, are the oldest existing group of machines in Japan in the history of silk-spinning technology, in addition to being a valuable resource for silk-spinning technology. Circular carding machines were made in Japan (by Ishii Iron Works) and were used to train silk-spinning technicians at the school. Furthermore, they are still used for silk-spinning practice and research.
The silk-spinning process can be classified into four processes: refining, silk milling, pre-spinning, and spinning and finishing.
