The technological empire begins with polymer materials

Xu Qingzhou and a dozen of his students gathered around Gao Yuan, each moved a chair and sat down, forming a small circle.

Looking across the crowd, Gao Yuan said with a smile: "Currently, there are five development routes in the field of heating fibers around the world."

"The first is far-infrared fiber. By incorporating alumina, magnesium oxide, zirconia, titanium dioxide, silica, etc. into the fiber material, it improves the absorption of external infrared rays such as sunlight, thereby achieving a heat storage and insulation effect. To put it simply, In other words, it absorbs heat from nature.”

"In this field, our Japanese counterparts are in an absolute leading position. Ceramino technology of Japan's Zhongbo Synthetic Fiber, DynaLive of Komatsu Seiko, INSERARED of Fujibo, and LONWAVE of Kuraray have occupied almost all market shares in the world."

"The second is near-infrared fiber, which also absorbs light and heat from nature. The dominant players are also Japanese companies, Unitika's Thermotron, Mitsubishi Rayon's Thermocatch, and Toray's Torayheat."

“Because the three major near-infrared fibers all start with the letter T, they are also called 3T. All products in the world with the name of far-infrared or near-infrared, whether they are Chinese brands or French brands, will eventually be purchased by consumers. Actually it’s all Japanese fiber.”

When Gao Yuan said this, a sigh came from the room.

People only know about ordinary chemical fiber products such as acrylic and spandex. Yes, our country can make these ordinary chemical fibers and the output is huge.

But those products at the top of the pyramid, which are the most profitable and have the highest technological content, are dominated by Japan, South Korea, Europe and the United States. The large number and high quality of their products simply make domestic students engaged in chemical fiber despair.

"The third one is electric heating, which generates heat through conductive fibers and built-in energy. The upper limit of this technology is very high. In the future, it may challenge ultra-low temperatures of about minus 100 degrees."

"However, it is a pity that it has a front-end technology tree that has not been lit up yet, and that is large-scale graphene preparation technology. Without graphene technology for electric heating, the efficiency is too low, so it is not within the scope of our consideration. .”

To this, the students nodded in agreement.

In fact, if large-scale graphene preparation technology is really developed, it will not only solve the problem of heating fibers, but also most of the current problems in the field of materials science can be solved overnight!

This is the powerful magic of basic subjects!

As long as a basic research is done, the whole world will benefit!

"The fourth is phase change temperature regulation technology." Gao Yuan spoke quickly and continued: "Using the principle of absorbing or releasing heat when the phase state of matter changes, it absorbs heat when the ambient temperature is high, and then when the ambient temperature is low It releases heat.”

"This technical difficulty and cost are relatively high. Currently, there is only one company leading the way. Outlast fiber is registered and produced in North America by the German Otterheim Group. I have carefully studied it and found that phase change temperature regulation technology should not be feasible. Everyone Just know it and don’t pay attention to it.”

"The next point is coming. The fifth major technological route in the field of heating fibers is moisture absorption and heating fiber technology. It is the technology closest to nature. For example, the well-known wool fiber is a typical moisture absorption and heating. When wool encounters moisture, , fiber molecules and water molecules attract and combine with each other, and the kinetic energy of the water molecules is rapidly reduced and converted into heat energy and released."

"Every winter, we like to wear sweaters. We think sweaters are warmer. Why?"

"It is because of the hygroscopic and heating properties of wool fiber that it can magically absorb body moisture and convert it into heat energy."

"Unfortunately, in the field of moisture-absorbing and heating fibers, the leader is still a Japanese company. The eks fiber developed by Japan's Toyobo absorbs moisture at a temperature of 20 degrees Celsius and a relative humidity of 65%. The capacity can reach three and a half times that of pure cotton, and it can absorb and release twice as much heat as wool!"

"In addition to eks fiber, Japan's Toyobo also has a higher-end N38 product line, Japan's Toray's Softwarm fiber, Warmsensor fiber, Japan's Asahi Kasei's Thermogear fiber, Japan's Mitsubishi Chemical's Renaissance α fiber, are also among the top in the world."

What the hell!

Why are there little Japans everywhere! ?

This is everyone's biggest feeling after listening to Gao Yuan's words.

Putting aside the unlit front skill trees and the two routes that are considered to have little development potential, there are three major technical routes left. No matter which direction you go, you will encounter strong competitors from Japan.

Moreover, these Japanese opponents are not one or two, but groups, piles, and huge numbers.

There is no way, just like the North American DuPont Group cannot be bypassed in the field of quick-drying fibers, in the field of self-heating fibers, it is impossible to bypass the Japanese Group. They have already formed a de facto monopoly in this field.

"As the old saying goes, good steel should be used on the blade. Even if X fiber has strong plasticity and great potential, we can't blindly pursue big and comprehensive." Gao Yuan said with emotion, "Let X2 fiber have both Far-infrared heating, near-infrared heating, phase change temperature regulation, plus moisture absorption and heating, is this good?"

"Of course it's great, but I'm afraid I'll bite off more than I can chew."

Gao Yuan's words were actually meant for himself.

When the subsystem started Task 3 a while ago, it also supplemented his knowledge.

So Gao Yuan relied on the knowledge provided by the system and began to plan a super all-round thermal fiber. As time passed by, he was still unable to succeed.

Now Gao Yuan finally understands that even if he has a system in his head, he can't do whatever he wants. He still has to eat his food one bite at a time.

Today's meeting is a meeting to determine the final technical route. From now on, we should concentrate on attacking the most critical point. We can no longer pursue the big and comprehensive.

Swish swish swish~

Gao Yuan wrote the English CLO on the blackboard, which means Crow value.

The Crow value is an international standard. Simply put, the higher the Crow value, the better the thermal insulation performance.

For example, the Cro value of cotton is 0.4, merino wool is 0.84, down with a fill power of 500 can have a Cro value of 1.7, and top down products with a fill power of 850 can reach an astonishing 2.53 Cro value!

Gao Yuan's pen tip continued non-stop, and soon, a blackboard was filled with material properties and the derivation route of the chemical fiber manufacturing process.

"It's very simple. Our goal is one fiber, two forms." Gao Yuan said solemnly: "In terms of chemical ratio, we want to make the X2 fiber have the characteristics of moisture absorption and heat generation, and in terms of technology, we want to improve the super The honeycomb structure turns the originally straight fiber filaments into fluffy fiber velvet.”

"In the end, we will use X2 fiber to compete with Toray, Asahi Kasei, Mitsubishi Chemical, Toyobo, etc. to form the Japanese chemical fiber group."

"Use X2 type fiber down to change the ecology of the entire clothing industry! Replace expensive duck down and goose down!"

As soon as Gao Yuan finished speaking, everyone applauded.

Many times, what people who engage in scientific research fear most is not the hard work, but the fear that they are unclear about the general direction, that laymen will lead experts, and that in the end they will waste their time and work in vain.

Plateau did take some detours before. It became systematic, its self-confidence expanded, and it blindly pursued high-end and comprehensive pursuits.

But fortunately, he corrected his mistakes when he knew they were wrong. When he realized that the situation was wrong, he returned to the right direction in time.

No matter how many research and development routes there are for heating fibers, the one that absorbs moisture and generates heat is enough for Plateau.

As for X2 fiber velvet, it is just a process improvement.

As we all know, the biggest highlight of X1 fiber is the super honeycomb structure.

As long as you carry out excessive puffing on this basis and let the super honeycomb structure pop like popcorn, you will get split fiber velvet.

Naturally, the fiber fleece body cannot be used to make fabrics, as it will fall apart when the wind blows. However, it can be stuffed into fabrics as a sandwich layer, or re-spun to make fleece, which can be used to knit fleece or sweaters.

All in all, materials science is the cornerstone of all industries.

Once the problem of basic materials is solved, there is not much that can be done.

Well, it’s over 50,000 words, and I feel like I’m getting into the zone.
