Due to the historical management system, the production level of the banner has been stagnant for a long time. The first five-star red flag raised in Tiananmen Square on October 1st, 1949 was made of red silk and yellow satin. Up to now, this method is still used in some areas. Therefore, in people's ideology, the technology of flag making is a small handicraft industry of "sewing, splicing, patching and embroidering", without much mystery. However, in fact, China's five-star national flag and the party flag of sickle and axe are decorated with yellow five-star or party emblem on a red background. The process of sticking and patching can not meet the demand in terms of appearance and output. In particular, the national flags of all countries in the world have a variety of shapes and colors. It is said that when China participated in the Bandung Conference in the mid-1950s, it asked China to provide the flags of Asian and African countries, began to try printing and dyeing technology, and tried every means to finish it. Forty years later, I saw that the samples at that time were almost the same as those at present. At that time, the national flag was made by the discharge process of printing and dyeing. The discharge technology in the 1950s was not perfect, and it was in the embryonic stage for small handicraft enterprises. Therefore, it was generally used to discharge white first and then dye yellow. Because they used direct dyes or basic dyes, their color fastness was relatively poor. But it is a big step higher than the appearance effect of sticking seam. Due to the quantitative supply of textile certificates, the production of various flags is restricted. For this reason, the Ministry of textile industry designated Shanghai to supply the national pure cotton national flag cloth, which was sewn in various places according to regulations and continued to the late 1970s.


Looking back on this period of history, we mainly show that before the reform and opening up, except for political flags, other flags were insignificant. Therefore, there was little research on flag technology, but the situation has changed greatly since the early 1980s. First of all, the types of flags have entered the market demand in an all-round way, so there are more varieties of fabrics. The fabrics used for the national flag have changed from pure cotton to Fuchun spinning (commonly known as colorful flag spinning) of man-made fibers and silk power spinning. The color drawing process has been gradually improved and the coating process has been fully used. Especially after the implementation of the "National Flag Law", the "national standard for the national flag" has been formulated to improve the appearance quality of the national flag and ensure color fastness. For this reason, the anti pulling process of disperse dyes for pure polyester silk like and wool like fabrics has been developed, so that the flag making technology has entered a new stage and gradually approached the international level.
