Because fossil resources are non-renewable, it is necessary to return to bio-based materials in the future, and use these as raw materials to develop petrochemical chemical fibers
.
Our next step is to lead the world and move towards higher-end high-quality development in this field

Because fossil resources are non-renewable, it is necessary to return to bio-based materials in the future, and use these as raw materials to develop petrochemical chemical fibers

Our next step is to lead the world and move towards higher-end high-quality development in this field
.
.
A large amount of synthetic fibers, or wood and cotton wool, are actually produced by planting and relying on this material, but this amount is very limited, because the Chinese still have to solve the problem of eating
.
At that time, by using petroleum as a raw material, a good way was found to solve the clothing problem of the Chinese people
.
, that is, relying on photosynthesis to produce green plants, its straw and waste, and use these to make chemical raw materials and chemical products
.
.
For example, we have studied the solvent-based regenerated cellulose fiber developed by modern industrialization.
It is called Lyocell in China.
This fiber was originally monopolized by Austria.
Now we have developed 30,000 tons of projects in China, and even 60,000 tons.
In addition, nylon 56 with Chinese characteristics has been developed, and now bio-based nylon 56 has been developed.
Among them, hexamethylene diamine is not chemically produced, but pentanediamine is made by fermentation
.
This is the direction leading the future, which is to have better technology
.
Because in the past, there was no bio-based, but its quality was not good and the cost was very high, which was unacceptable in the market
.
But now with the advancement of science and technology, it can return to photosynthesis, which can be sustainable, recyclable and renewable
.
To find a new way out, it happens that the world is developing bio-based raw materials, that is to say, the original petroleum refining is now called bio-refining, and the green plants produced through photosynthesis, or the wastes of green plants, or It is straw, how to make better comprehensive utilization and make its effective components into chemical products, this is to rely on scientific and technological progress and innovation
.
Of course, this task is very arduous, and there is a long way to go.
I believe this is definitely a way to return to nature and return to recycling and renewable development.
Above, this is very correct.
The petrochemical industry, chemical fiber industry, and textile industry must make some efforts to this end
.
At that time, we had to develop rapidly to meet the needs of the people and increase the market's requirements for these aspects.
, and turned to the field of petrochemical chemical fiber.
After 50 years of development, it has reached a very high level.
Of course, there is still room for improvement.
However, due to the constraints of the entire environmental resources, our development direction will definitely change
.
.
Now it happens to be an alternate stage.
Petrochemical chemical fiber is a peak stage.
It may continue to improve and the output will increase.
However, due to these environmental restrictions, carbon emission problems, environmental pollution problems, etc.
, this area will become more and more Restricted by society, it must be transformed and developed, and it must be developed with high quality
.
The next step is to take technological innovation as the focus of development.
As a cutting-edge technology, it must be transferred to this direction as soon as possible
.
I have just given an example.
The industrialization of bio-based fibers should be said to be in an advanced or even leading position in the world
.
For example, the polylactic acid just mentioned, used to be made of grain and corn, but corn is a feed, and the stock is also limited.
It is far from enough to really meet the needs of chemical industry
.
However, the straw in rural areas is 600 to 700 million tons a year, which is a very large and precious resource.
Of course, it can be used in many ways, but it is a very important direction to be able to make it into chemical raw materials
.
It turns out that straw has cellulose, hemicellulose and lignin in it
.
It has to be separated separately, and then processed and utilized, which is relatively difficult and the conversion efficiency is relatively low
.
After pulverizing the whole straw, through high-throughput screening, a fermenting bacteria was found, which can be converted into sugars at a relatively high concentration, and then the sugars are used to make the following energy products, including chemical products
.
Of course, there is a lot of help provided by the government.
How to recycle straw and how to distribute it is very likely to embark on a path of Chineseization
.
It is definitely a direction to be able to turn rural waste into valuable and high-quality chemical products that are acceptable in terms of cost
.
