The Past And Present Of Fabric Printing And Dyeing Technology In China

< p > printing and dyeing, also known as dyeing and finishing, is a process of < strong > a > fabric > /a > /strong > processing. It is also a general term for dyeing, printing, finishing and washing. Six, seven thousand years ago in the Neolithic age, our ancestors were able to dye linen red with red hematite powder. Primitive tribes living in the nuohong area of the Qaidam Basin in Qinghai can dye wool into yellow, red, brown and blue colors and weave cloth with color stripes. During the Shang and Zhou dynasties, dyeing technology was constantly improving. In the palace handicraft workshop, there are full-time officials who "dye people" to "palm the grass" and manage dyeing production. The color is also increasing. In the Han Dynasty, dyeing technology reached a fairly high level. < /p >
< p > in China, < strong > a href= > http://cailiao.sjfzxm.com/Matertial/show/default.aspx > fabric > /a > /strong > printing is later than painting, embroidery and embroidery. The earliest printed fabric we have seen is the printed cloth quilt unearthed from Chu Tomb of the Warring States period in Changsha, Hunan. In Central Plains, the revival of printing technology started from vale, and valerian, valerian, and valiant. It is actually a kind of imitation printing fabric. The printing and dyeing industry in the Tang Dynasty is quite developed. Besides the improvement of the quantity and quality of valerian, some new printing and dyeing processes have also appeared, especially in the Tang Dynasty in Dunhuang, Gansu. From the unearthed Tang Dynasty textiles, a number of invisible printing and dyeing processes were also found. In the Song Dynasty, the printing and dyeing technology in China was more comprehensive and the chromatography was more complete. By the Ming and Qing Dynasties, the application technology of dyestuff has reached a considerable level in China. During the Qianlong period, some people described the dyeing house in Shanghai: "dyed workers have blue squares, azure, light green, white under the moon; red houses, dyed red and pink; there are bleaching houses, dyed yellow and rough white; there are motley houses, dyed yellow, green, black, purple, shrimp, green, and Buddha gold." In addition, more sophisticated printing technology has also developed. Until 1834, before the invention of Perot printing machine in France, China has always had the most developed manual printing and dyeing technology in the world. < /p >
The development of China's fabric < strong > a > printing and dyeing < /a > /strong > has been highly valued by the government and the textile industry. P In recent years, the state has included the technological transformation of the printing and dyeing industry in one of the key industries supported by the textile industry. At the same time, it has also provided corresponding policy support in technological development and tackling key problems in science and technology, so that China's printing and dyeing industry has been greatly improved in terms of quality, variety and efficiency, and its overall competitiveness has been improved, but the improvement of production capacity and economic efficiency is out of sync. The reason is that China's printing and dyeing products are of low grade and low added value; they neglect the impact on nature and society; independent brands are few, and R & D capability is poor. Besides, online detection and control technology, new equipment development, manufacturing accuracy and fittings, energy saving, environmental protection and after-sales service are also lagging behind advanced foreign countries. Therefore, the printing and dyeing industry should strengthen technological innovation and improve product quality. The state has promulgated corresponding policies to control printing and dyeing enterprises with serious pollution, improve the environment, advocate the harmonious development of production and environment, and increase investment in science and technology. < /p >
