Traditional cotton textile technology (Leigou Dabu making technology, Fengxian cotton textile technology) extends to Leigou, which is located in Houcheng and Nansha of Jingang Town, Zhangjiagang City, Suzhou. During the Song and Yuan Dynasties, cotton was widely planted in Leigou, and the people spun and wove cloth, "every family had the sound of a machine, and every household spun cloth". The people spun and wove their own cloth. This kind of cloth was originally made of Du warp and Du weft, so it was called Leigou Dubu. Because the dialect "Du" and "Da" are homophones, it is also called "Leigou Dabu". During the Ming and Qing Dynasties, Leigou Dabu was a unique one in Jiangnan and was well-known at home and abroad. Beijing's "Ruifuxiang" cloth shop, Nanjing's "Hengyuanda" cloth shop, Yangzhou's "Lao Xiesheng" cloth shop, etc. all sell Leigou Dabu, and the cloth shops in the north and south transport it to Southeast Asia. There are cloth shops in the towns around the Leigou area. According to incomplete statistics, there are 40-50 cloth shops, and Leigou Dabu was very popular. Every day, 15,000 to 20,000 pieces of Leigou cloth can be purchased, and there are dyeing workshops and dye shops everywhere. The Qing Dynasty poet Tao Fuyin praised it in a poem: "The Jiahu Plain competes for beauty, and the local cloth produced in the county is mostly Leigou." In the late Qing Dynasty and early Republic of China, in addition to spinning and weaving in every household, private cloth factories began to rise. Around 1934, Leigou cloth was changed from hand-throwing shuttle to pulling shuttle loom. The cloth width was changed from 8.3 inches to 92 inches, called "size" cloth, and the length was changed from 224 feet to 34 feet. In addition, the dyeing was changed from leaves and river mud to chemical dyeing (no fading). In 1958, cotton weaving societies such as Houcheng, Nansha, and Zhashang were established. Subsequently, textile factories run by brigades (villages) emerged, and almost every village had a textile factory. In 1974, some technical backbones and management personnel of Leigou Dabu used 16 looms diverted from the cotton weaving society to establish Houcheng San Chemical Fiber. In 1997, the company was renamed "Zhangjiagang Jinling Textile Co., Ltd." Leigou Dabu uses pure cotton to be spun by hand, woven on old wooden looms, and dyed with natural plants, with exquisite dyeing and weaving skills. The cloth is soft and thick, firm and fine, has strong sweat absorption, and is extremely warm. It can be said to be warm in winter and cool in summer, and has a wide range of uses. It can be used to make: clothes, socks, pants, headscarves, aprons, car bags, hand towels, gloves, sheets, quilts, linings, bellybands, table blankets, school bags, bundles, etc. Leigou Dabu weaving and dyeing techniques are representative of Suzhou's local cloth weaving and dyeing, and have written a rich and colorful page in the history of textile and clothing in the Jiangnan region. Research on Leigou Dabu is of great significance to the study of the historical situation of the vigorous development of the national industrial economy and township industries in this region, and to the guidance of current industrial development.
