We must know that at the beginning of the founding of the People's Republic of China, due to the backward economic development, the development level of social productive forces was low and the demand was in short supply. In terms of clothing, everyone wears cotton-padded clothes and trousers. There is an extreme shortage of textiles because cotton is in short supply. In addition to natural disasters such as floods, China has strict requirements for food supply. So many people don't change clothes, so they can only wear a few patches. That's why people at that time often wore patched clothes.
In order to solve the problem of people's dressing, a mixture of natural fiber and chemical fiber is put forward. However, when it comes to the development history of man-made fiber industry, it is not as easy as before. Due to the lack of raw materials and technical limitations, the man-made fiber made of it can not meet people's needs.
Then, with the development of China's economy, people's demand for clothing has increased. In order to solve this problem, they made "polyester" shirts. This kind of fabric is made of polyester, which is more wear-resistant than cotton-padded jacket and does not fade easily. Can be made into various colors.
China spent $4.3 billion to import equipment and technology. However, nylon shirts are really expensive and can only be imported from abroad, so they cannot be widely used nationwide. It was not until 1973 that the famous "43 Plan" was approved. Our country spent a total of 4.3 billion dollars, imported equipment and technical solutions, and opened a chemical plant specializing in the production of chemical fiber in this country.
Since then, through long-term technical research, China has been able to independently produce chemical fiber, and gradually developed into a strong chemical fiber country, achieving a qualitative leap. Relying on this technology, the long-standing clothing problem of ordinary people has finally been solved. They can wear new clothes of various styles and colors instead of heavy cotton-padded clothes.
Today, although that history has become a thing of the past, "polyester" is no longer respected by people. But he is still an unforgettable "hero" who changed the history of China. At that time, China dared to introduce foreign technology to develop chemical fiber, which also laid a solid foundation for accelerating the industrialization process, improving productivity and enhancing the technical and equipment strength of China.
