If Bai Wutong hadn't ascended the throne as the Empress, Southern Border was still the territory of Ling State, and they could purchase a large amount of cotton from Ling State.

But now, it is obviously impossible to do business with Ling country.

They planted a lot of kudzu, but the linen or clothes made of kudzu are far less comfortable and breathable than cotton, and the rough craftsmanship is even abrasive.

The increase in the price of wool when the supply exceeds demand is caused by the market. Forcibly suppressing the price will cause dissatisfaction among the Syrian people.

But blindly accommodating their prices will also keep the price of cotton cloth high, and the common people can no longer afford cheap and comfortable cloth.

Now it is necessary not only to regulate the market price, but also to fully adjust the market demand.

In fact, the cloth made of cotton, wool, and silk is not cheap compared to the price of linen. In modern times, a short sleeve marked with 99% pure cotton is often very expensive.

Everyone is used to it, and synthetic materials such as chemical fibers are prevalent in the city.

Chemical fiber is the most common man-made clothing material. It is extracted from petroleum, and is named nylon, acrylic, etc. according to different materials.

It is a chemical compound in which petroleum is converted into a liquid through refinery processing, and then extruded to form chemical fibers. These fibers have many advantages, such as anti-ultraviolet, anti-pilling, abrasion resistance, etc., which just make up for the lack of natural fibers. place.

Therefore, many modern clothes, labeled pure cotton, actually add a lot of chemical fibers.

The supply of cotton was insufficient, and Bai Wutong immediately thought of oil as a raw material substitute.

A batch of oil was shipped last time, some fuel oil was extracted, and the waste was made into asphalt, and there are still some left.

Bai Wutong thought about it for a long time, anyway, he has already got this job, and it is not too surprising to use oil to make clothes.

She asked people to burn the oil waste at high temperature and tear it into filaments, and called in Hai Dongli, another big boss in the scientific research room.

Hai Dongli is a mute, before Bai Wutong discovered his talent, he always liked to tinker with some weird things that would go to heaven.

Everyone thought he was a lunatic, only Bai Wutong said he was a genius after seeing the flying mold he made, and recruited him into the research institute.

Hai Dongli is very grateful to Bai Wutong for his recognition, and is also very satisfied with the environment of the research institute. He stays in the research room every day and often forgets to eat.

People give it a nickname, Big Bee, the kind that wants to go to heaven all day long.

After Bai Wutong knew about it, he specifically asked someone to be his assistant.

Take care of his diet.

He is even more grateful to Bai Wutong, but he will do his best to research everything that Bai Wutong needs, and even explore the prototype of the engine according to Bai Wutong's guidance, which can directly skip the steam age.

Bai Wutong came looking for him suddenly, Hai Dongli's scruffy beard could be used as a broom, fearing that it would smoke Bai Wutong, he hurriedly washed and tidied up before coming to see Bai Wutong.

Hai Dongli can't speak, but his eyes are very bright and full of wisdom.

Bai Wutong shot straight in, and put the oil waste torn into silk in front of him, "I think its material can replace cotton and become the main daily fabric, what do you think?"

Bai Wutong has extraordinary courage, extraordinary intelligence, and mysterious aura that is unpredictable. Before Hai Dongli picked up the piece of petroleum waste, he felt that what Bai Wutong said was not a question, but a question. Affirmative.

He tugged at the silky oil waste, sniffed it under his nose again, and felt that his consciousness just now was wrong.

Such a black mass of petroleum waste with such a strong smell is still hard, how can it be made into a soft material that can replace cotton.

Hai Dongli couldn't guarantee it, and gestured with his hands, "I can try."

It is also impossible for Bai Wutong to let him study like a chicken without a head. If he does not have a general direction and does not know how long it will take to detour, he can master the real technology.

Bai Wutong handed the old drawings made in advance to him, "This is the metal casting purification method I read in an ancient book, I think you should be able to use it."

Although it is just a rough and simplified reminder, Bai Wutong believes that given him a little time, chemical fiber will not be too far away from entering thousands of households.

Hai Dongli took a look at the blueprint of Bai Wutong, and it was a process of transforming oil into some kind of substance, and then condensing it into a kind of resin-like high-grade compound, and extruding silk threads through extrusion. A form is drawn.

This process looks quite simple, but I don't know if it is as simple to operate.

Hai Dongli connected the drawings, and gestured to Bai Wutong again, "I will do my best."

Bai Wutong nodded, "I'm waiting for your good news."

Hai Dongli kowtowed and left the study.

Bai Wutong looked at the falling leaves outside the window. The process of making chemical fiber is actually not difficult. What is difficult is the mass production and operation of chemical fiber equipment.

This needs to overcome a lot of principles, I hope he can go well, otherwise, when the child is born, I will still be tired.

Hai Dongli returned to the research room, and many people brought him a lot of oil.

Others in the research room thought that he came up with something, which was appreciated by Bai Wutong and rewarded him.

They came over to watch the fun, but the whole room smelled like a lot of oil. They wanted to ask him what he was doing with the oil, but remembering that he couldn't speak, he held back the words.

Petroleum is flammable and explosive

For dangerous goods, Bai Wutong opened up a separate space for Hai Dongli in the backyard of the scientific research room for him to conduct experiments.

Haidong already has many experimental areas by himself, and now there is another one, which everyone is very envious of.

Haidongli didn't care about other people's curiosity, and devoted himself to the experiment of refining chemical fiber.

He repeatedly operated according to the steps on the drawing, and soon produced the spinning fluid, but the color and feel of the spinning fluid were not satisfactory, and even the bark clothing was softer than it.

Haidongli also did a lot of research on spinning fluids, and recruited female textile workers to get inspiration from them.

He also looked through various possible related books, and finally, in the teaching plan given by Bai Wutong to everyone to make white paper, he found the relevant mixing, filtering, defoaming and other processes to overcome the spinning fluid.

After a while, he finally got the snow-white spinning.

During this period, he also made a self-made spinning machine to quickly collect all the spinning, which is convenient for female workers to use directly.

When the female worker produced the first piece of chemical fiber fabric overnight, Hai Dongli could not help shaking his hands as he touched the soft and silky fabric like satin.

He succeeded, and he used the black oil to develop the cloth that the Empress wanted to replace cotton.

Hai Dongli danced excitedly, and other people in the scientific research room walked in, didn't look at the fabric he was holding in his hand, but walked towards several dark containers in the field, and asked, "Is this a new product you're researching?"
