China's bio-based fiber industrialization is in an advanced or even leading position in the world. Because fossil resources are not renewable, it is necessary to return to bio-based materials in the future and develop petrochemical fiber with these as raw materials. Our next step is to lead the world in higher-end, higher-quality development in this field.
China's chemical fiber industry, which developed gradually after liberation, was very weak in the 1960s and 1970s.
A lot of synthetic fiber, or wood, or cottonseed wool, is actually grown, produced from this material, but it's very limited because the Chinese have to eat. At that time, oil was used as raw material to find a good way to solve the clothing problem of the Chinese people.
Bio-based fibers are carbon neutral
Because it is non-renewable fossil resources, so as the oil resources in the next 50 years, or longer, may be less and less resources, but these materials, the demand is becoming more and more in the future or to return to the biological base material, which is in the production of green plants by photosynthesis, straw, waste it, with the chemical raw materials, to do again to do chemical products.
In the field of chemical fiber, our research is synchronized with that of foreign countries, and we have developed a lot of things of international advanced level in bio-based fiber industry. Of modern industrialization development such as call solvent method of regenerated cellulose fiber, domestic call self, the fiber is Austria monopoly, we now China has developed over 30000 tons of projects, even with 60000 tons, is also developed with Chinese characteristics of nylon 56, and now the biological research and development base of nylon 56, including its hexamethylenediamine, now don't use chemical industry, It's made by fermentation.
In terms of bio-fiber, China is no worse than other countries, and in some areas, China is still ahead in industrialization. This is the direction for the future, which is to have better technology. Because in the past biological base is not without, but its quality is not good, the cost is high, the market can not accept. But now with advances in technology, it's back to photosynthesis, it's sustainable, it's recyclable, it's renewable.
There is a long way to go in biorefinery
Many products are now rely on petroleum and chemical raw materials, and a relatively long time in the future, depends on petroleum chemical industry, but can never depend on petroleum chemical industry, slowly because of oil resources will be less and less, the future is to find a new way out, just in international research and development, the biological base of raw materials, that is to say the original oil refining now call biological refining, The green plants produced through photosynthesis, or the waste of green plants, or straw, how to make better comprehensive use of its effective ingredients into chemical products, this is to rely on scientific and technological progress and innovation.
China and abroad are synchronous in doing research, and we have some aspects of the industrialization also went before him, and, of course, this task is very difficult, want to go, I believe that this must be a return to nature, return to the circulating renewable development path, this is very correct, petrochemical industry, chemical industry, textile industry should be to do some efforts.
Doing at first China is relatively low-end cotton linen, silk, regenerated cellulose and viscose fiber, quality and technical level is relatively low, at the time we want to rapid development to meet the needs of the people, increase market demand for these aspects, they turned to the petroleum and chemical fiber in this area, through 50 years of development, has reached a very high level, of course, there are still room for improvement, However, the overall environmental resources constraints, our development direction must change.
Fiber transition to high quality development
Return to the original photosynthetic green plants, or its straw waste, with these as raw materials to develop petrochemical chemical fiber. Just now is an alternating phase, petroleum and chemical fiber is a peak stage, may also be progress, production will increase, but because of the limitation of these environmental emissions problem, the problem of environmental pollution and so on, this is will be more and more subject to the conditions of society, so must be the transformation of development, but also to the development of high quality. The next step is to take scientific and technological innovation as the focus of development, as cutting-edge technology, to move to this direction as soon as possible.
From the fiber point of view, we are moving very fast, as I mentioned earlier, the industrialization of bio-based fibers, and these applications are in an advanced, even leading position in the world. For example, polylactic acid, which I just mentioned, used to be made from grain and corn. However, corn is fodder and its stock is limited. It is far from enough to meet the needs of chemical industry. But the rural straw a year 600, 700 million tons, this is a very large precious resource, of course, the use of it is in many ways, but it can be made into chemical raw materials, this is a very important direction.
Now in the field of chemical fiber, there are some innovative technology enterprises, have studied the recycling of the whole straw, the original straw it contains cellulose, hemicellulose, lignin. To separate it, and then reprocessing, this difficulty is relatively large, and conversion efficiency is relatively low. After crushing the whole straw, a high-throughput screening was carried out through it to find a kind of fermentation bacteria that can be converted into sugar in relatively high concentration. Then, these energy products, including chemical products, can be made through sugar.
In Taiyuan is building a 10,000-ton test device, of course, with a lot of help provided by the government, how to recycle straw how to spread, it is likely to walk out of a Chinese way. To be able to turn rural waste into valuable, high-quality, and affordable chemical products is definitely a direction.
The chemical fiber industry in China through the 40 years, from 1980 to 2020, during the period of 40 years, our chemical fiber industry, from scratch, from there to big to strong, has been very poor, poverty, from the past to the present can provide all kinds of advanced fiber materials, textile industry and advanced chemical fiber you need to solve the livelihood of the people of various powers. Our next step is to lead the world in higher-end, higher-quality development in this field.
Xuzhou Heping Chemical Fiber Co., Ltd. is located in Xuzhou, Jiangsu. It has focused on the research and development and production of polypropylene, high strength, high strength, high strength, high strength, anti-aging, acid and alkali resistant, etc., which also make polypropylene high strength. Wire can be applied to all aspects of our lives. Peaceful chemical polypropylene, manufacturers supply, complete products, high quality after-sales service, users can rest assured to buy. Peace chemical fiber also has a polypropylene industrial silk, polypropylene high strength wire, high-strength polypropylene wire, polypropylene high strength, high-strength propylene, and hydrazine industrial wire.
