Who knows what is the raw material of ancient clothes in China?

According to the analysis of flora and historical data, it is generally believed that cotton spread from north to south to the Central Plains. South Road cotton first appeared in Hainan and Lancang River basin, and then spread to Fujian, Guangdong, Sichuan and other regions. North Road starts from the northwest, which is called "Western Regions" in ancient books. During the Song and Yuan Dynasties, cotton spread from the north and south to the vast areas of the Yangtze and Yellow River basins. By the13rd century, the cotton on the North Road had spread to the Weishui Valley in Shaanxi. At the beginning of the Yuan Dynasty, the Kapok Lifting Department was set up to collect cotton products from the people on a large scale, with an annual output of 65,438+10,000. Although this system was abolished soon, cotton cloth was later regarded as the top of summer tax (cloth, silk, silk and cotton), which shows that cotton cloth has become one of the main textile materials. Cotton is a rising star in China's textile raw materials. Since the Tang and Song Dynasties, people have increasingly seen the superiority of cotton as a batting lining and textile raw material. "Agricultural Book" made a more comprehensive evaluation of this, saying that cotton "is more effortless than silkworm, and has certain effects. It can be said that bamboo can be used as a blanket to make up the cost of brown clothes. After the Yuan Dynasty, all the rulers tried their best to collect cotton cloth, publish books on cotton planting techniques and persuade people to grow cotton. By the Ming Dynasty, cotton had surpassed silk, hemp and wool to become the main textile raw material. Song said in "Heavenly Creations" that "cotton cloth is everywhere" and "there must be ten looms", which shows that cotton planting and cotton textile industry were all over the country at that time.
