Xu Qingzhou and his dozen of his students surrounded the plateau, each bringing chairs to sit down, forming a small circle.

With his eyes swept across everyone, Gao Yuan smiled and said, "At present, there are five development routes in the field of heating fibers in the world."

"First of all, far-infrared fibers, by incorporating alumina, magnesium oxide, zirconium oxide, titanium dioxide, silica, etc. into the fiber materials, improve the absorption of external infrared rays such as sunlight, thereby achieving a heat storage and insulation effect. In short, it is to absorb heat from nature."

"In this field, our Japanese peers are in an absolute leading position. The Ceramine technology of Japan's Bellstone Fiber, the DynaLive of Komatsu, the INSERARED of Fujimoto, and the LONWAVE of Colari have already occupied almost all the global market share."

"The second is near-infrared fiber, which also absorbs the light and heat of nature in principle. The dominant Japanese companies are also Japanese companies, Thermotron of Unigiko, Thermocatch of Mitsubishi Rayon, and Toray's Toray."

"Because the three near-infrared fibers all start with the letter T, they are also called 3T. All products in the world that are in the name of far-infrared or near-infrared, whether they are Chinese or French brands, consumers finally buy them, are actually all Japanese fibers."

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

People only know ordinary chemical fiber products such as acrylic and spandex. They are not bad. These ordinary chemical fibers can be made in my country and have huge output.

But those products that are located at the top of the pyramid, with the most profitable and technological content are among the worlds of Japan, South Korea, Europe and the United States. Their products are so numerous and high-quality that they simply make students working in chemical fibers in China feel desperate.

"The third is electrical heating, which generates heat through conductive fibers and built-in energy. This technology limit is very high and may challenge ultra-low temperatures around minus one hundred degrees in the future."

"However, unfortunately, it has a pre-tech tree that has not been lit yet, that is, large-scale graphene preparation technology. The efficiency without graphene technology is too low, so it is not within our consideration."

In response, 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 achieved overnight!

This is the powerful magic of basic disciplines!

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

"The fourth is the phase change temperature regulation technology." Gao Yuan said quickly and continued: "Using the principle of absorbing or releasing heat when the phase state of a matter changes, it absorbs heat when the ambient temperature is higher, and then releases heat when the ambient temperature is lower."

"This technology is relatively difficult and costly. Currently, there is only one company leading the way. The Outlast fiber registered and produced by the German Ottheim Group in North America. I have carefully studied it. The path of phase change temperature regulation technology should not be possible. Just know it, don't care about it."

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

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

"It is because of the moisture absorption and heat-generating properties of wool fibers that can magically absorb body moisture and convert it into heat energy."

"However, unfortunately, in the field of hygroscopic heating fiber, the leading position is still the Japanese company. The eks fiber developed by Japan Toyo Strings has a hygroscopic absorption capacity of 3.5 times that of cotton pure cotton under the conditions of temperature of 20 degrees Celsius and relative humidity of 65% and a full twice that of wool!"

"In addition to eks fiber, Japan Toyo Stylus also has a higher-end N38 product line, Japan Toray's Softwarm fiber, Warmsensor fiber, Japan Asahi Kasei's Thermogear fiber, and Japan Mitsubishi Chemical's Renaiss alpha fiber are also ranked among the top in the world."

What the hell!

Why are there little Japan everywhere!?

This is everyone’s biggest feeling after hearing what Gao Yuan said.

Putting aside the two routes that were not lit up in the front skill tree and 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 a group of people, a lot of people.

There is no way, just like the fast-drying fiber field cannot avoid the North American DuPont Group, in the field of spontaneous heating fiber, it is impossible to bypass the Japanese group in any case. They have already formed a factual monopoly in this field.

"The old saying goes, good steel should be used on the blade. Even if X fiber has strong plasticity and great potential, we cannot blindly pursue large and completeness." Gao Yuan said with emotion, "Is it good to let X2 fibers have far-infrared heating, near-infrared heating, phase change and temperature adjustment, plus moisture absorption and heating, is it good?"

"Of course it's great, but I'm afraid I won't be able to chew too much."

Gao Yuan said this to himself.

A while ago, the system started Mission 3 and also supplemented his knowledge.

So the plateau relied on the knowledge provided by the system and began to plan a super all-round warm fiber. As a result, time passed day by day, but he was still unable to succeed.

Now Gao Yuan finally understood that even if he had a system in his head, he could not do whatever he wanted, and he still had to eat it one by one.

Today's meeting is a meeting to determine the final technical route. From now on, we will concentrate our energy and attack the most critical point. We can no longer pursue the big and completeness.

Plateau writes down English CLO on the blackboard, which means Crow value.

The Crow value is an international general standard. Simply put, the higher the Crow value, the better the warmth performance.

For example, the Cro value of cotton is 0.4, Merino wool is 0.84, and down with a fluffy degree of 500 can reach 1.7, while the top down products with a fluffy degree of 850 can reach an astonishing 2.53 Cro!

The pen tip of the plateau is still constantly, and soon, a blackboard is full of material characteristics and deduction routes for chemical fiber manufacturing processes.

"It's very simple. Our goal is one fiber, two forms." Plateau said in a deep voice: "In terms of chemical ratio, we need to make X2 fibers absorb and heat, and in terms of technology, we need to improve the super honeycomb structure so that the originally straight fiber filaments can become fluffy fiber velvet."

"In the end, we will use X2 fiber wire to fight against Toray, Asahi Kasei, Mitsubishi Chemical, Toyoshi, etc. to form the Japan Chemical Fiber Group."

"Use X2 fiber velvet 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, people who do scientific research are most afraid of not working hard, but rather that they are not clear about the general direction, and that they are afraid that they will waste their efforts and work hard in the end.

The plateau did take some detours before, and it was systematic, and its self-confidence expanded. It blindly pursues high-end and pursues big and complete.

Fortunately, he corrected the mistake when he knew it. After finding that the situation was wrong, he returned to the right direction in time.

No matter how many routes are used for the development of heating fibers, it is enough to absorb moisture and heat the 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 over-expand on this basis, let the super honeycomb structure explode like popcorn, you will get split fiber velvet.

Naturally, the fiber velvet cannot be used as fabric. The thing dissipates when the wind blows, but it can be stuffed into the fabric as a sandwich, or re-spun to make velvet thread, which can be used to knit velvet coats or sweaters.

In short, materials science is the cornerstone of all industries.

Once the problem of basic materials is solved, there are not too many things that can be done.
