Viewing the Role of Jacquard Technology in the History of World Science and Technology Development from the Han Dynasty Jacquard Machine

        A Silk Road showcases China's exquisite silk to the world, with so many exquisite patterns, exquisite textile technology, and massive production. How did it happen? In 2012, the excavation of the Han Tomb at Laoguanshan in Chengdu uncovered a history that had been sealed for over 2000 years

          The excavation of four Han Dynasty jacquard looms proves that we had already started using this large textile machine too early in the Western Han Dynasty. So how did this jacquard loom actually operate? Can we now use the Han Dynasty loom to restore the weaving process of the "Five Stars Bringing Eastern Power to China" brocade protector, which is a very difficult Han Dynasty brocade? How difficult is the restoration of the Five Star Brocade

Before discussing Han brocade weaving, let's take a look at the historical background. The Han Dynasty was a very prosperous era in Chinese history. It continuously expanded its territory, made progress in mentality, and promoted the development of production in the field of flying shovels. One noteworthy aspect is the significant progress in the textile industry. We know that by the Han Dynasty, silk was no longer an exclusive product of the upper class, and ordinary people were also able to consume regular varieties of silk

During the Han Dynasty, silk production was mainly concentrated in the middle and lower reaches of the Yellow River basin and the Sichuan region. The silk production in the Yangtze River Basin during the Ahe era has not yet entered the entire people's vision. We know that after the Qin Dynasty unified the six countries, a large number of wealthy individuals from the six countries moved to Sichuan, bringing a lot of human and intellectual resources to Sichuan, greatly promoting local production in Sichuan. In the Western Han Dynasty, a Jin Guan was established in Chengdu, which is known as the "Jin Guan City with heavy flowers". If we travel to Chengdu now, we can see Jinli, which was the gathering place of the silk industry at that time. There is also a Jinjiang River in Chengdu, named after the use of its water to wash brocade, which has very beautiful colors
