He has only a high school education, but what he developed is that Americans are willing to spend 600 million to buy it. He rejected the money and left his research in China. His research and development is "the world's eighth largest man-made fibers," to achieve the Chinese people in the history of man-made fiber zero breakthrough. Americans get 600 million to buy his research results In 2001, Li Guanqi developed "plant protein synthetic silk and its manufacturing method" won the patent certificate issued by the State Patent Office. Until a bunch of Americans broke into his hometown - Huashan County, Walled County, to get 600 million to buy him such things, the village people know Li Guanqi's "baby" so valuable. Li Guanqi refused to buy the Americans. He valued the significance of this technology for China because it is the "eighth largest man-made fiber in the world" and achieved a zero breakthrough in the history of Chinese man-made fibers. In 1977, when he resigned as a captain of a production team in high school culture, he started to go out to start a business. By 1990, after more than 10 years of primitive accumulation, Li Guanqi has made tens of millions of dollars in personal possessions. In 1991, Li Guanqi saw a translation in Chemical Abstracts saying that "Soybean protein in soybean meal can pull out the fiber and spun into cloth," arousing his great interest. In his own words, "I Immediately pull your finger count the cost and profit of soybean fiber production, that is much stronger than the development of feed equipment. " R & D involves chemistry, physics and other knowledge, he bought a large number of high school graduation books self-study. Many alphabet symbols do not understand, and bought all kinds of dictionaries and other tools to check, a little groping for progress. All cast into the savings, but again failed again. Originally also support his family advised him to give up, he did not listen, ran to Puyang 50 kilometers away from home to engage in experiments, a rare home all year round. In 2001, after owed a debt, cost more than 3000 million yuan, before and after more than 800 trials, he finally succeeded. He made the underwear from the fiber extracted from soybeans In September 2003, he was invited to attend the world conference on artificial fibers in Austria. Soybean protein fiber was recognized as "the eighth man-made fiber in the world" and was officially loaded into man-made fiber. History, so that our country has become the world's only industrialized production of textile fiber with soybean countries. In December the same year, Li Guanqi won the World Intellectual Property Organization invention patent gold award and the Chinese Intellectual Property Office invention patent gold medal. After obtaining the patent certificate, Li Guanqi did not give up, he thought it prompted to become a product. He said that soybean fiber is mainly extracted from soybean meal, which belongs to the comprehensive utilization of waste. The cost is also low, only one-third of silk and one-fifteenth of cashmere. In 2005, he created an annual output of 1.2 million (sets) of soybean fiber upscale underwear production line put into operation in Huaxian, end-products fully market, causing a sensation in the world. But he is not satisfied with it yet. Since 2002, he also selected topics on the performance of soybean fiber research and development, has successfully studied its anti-UV function, antibacterial antibacterial function and negative oxygen ion function, making the end product diversity.
