If Bai Wutong hadn't been enthroned as the Empress, the Southern Border would still be the territory of Ling Country, and they could have purchased a lot of cotton from Ling Country.

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

They have 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 price increase of wool when the supply is in short supply is caused by the market. Forcibly suppressing the price will lead to dissatisfaction among Syrians.

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

Now we must not only regulate market prices, but also fully regulate 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 fabrics such as chemical fibers are prevalent in the market.

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

It is a compound that oil is converted into a liquid through refinery processing, and then extruded to form chemical fibers. These fibers have many advantages, such as UV protection, clothing pilling resistance, abrasion resistance, etc., which just make up for the lack of natural fibers. place.

Therefore, many modern clothes, products marked with pure cotton, actually add a lot of chemical fibers.

Insufficient supply of cotton, Bai Wutong immediately thought of oil as a raw material alternative.

A batch of oil was shipped last time, some of which were extracted for fuel oil, and the waste was made into asphalt, and now there is still some left.

Bai Wutong has thought about it for a long time, and it is not too surprising to use petroleum to make clothes anyway.

She asked people to burn the oil waste into filaments at high temperature, and found another big man in the research room, Hai Dongli.

Hai Dongli is a mute. Before Bai Wutong discovered his talent, he always liked to fiddle with some strange things that were going to heaven.

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

Hai Dongli was very grateful to Bai Wutong for his recognition of him, and he was very satisfied with the environment of the research institute. He spent every day in the research room and often forgot to eat.

People give the nickname, the big bee, the kind that wants to go to the sky all day.

After Bai Wutong found out, he specially instructed someone to be his assistant and take care of his diet and daily life.

He is even more grateful to Bai Wutong, but he will study everything Bai Wutong needs, and even according to the guidance of Bai Wutong, he has explored the prototype of the engine, and can skip the steam era directly.

Bai Wutong suddenly looked for him, Hai Dongli's scruffy beard could be used as a broom, and he was afraid that Bai Wutong would be smoked, so he quickly washed and sorted out Bai Wutong before he came to see Bai Wutong.

Haidongli can't speak, and his eyes are very bright and full of wisdom.

Bai Wutong went 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 an unpredictable mysterious atmosphere. Haidongli has not picked up the piece of oil waste, so he feels that Bai Wutong is not saying a question, but a question. Affirmative.

He tugged at the silky substance of the oil waste, sniffed under his nose again, and felt that his previous consciousness was wrong.

How could such a dark mass of oil waste with such a strong smell be made into a soft material that can replace cotton?

Haidongli couldn't guarantee it, and gestured with his hand, "I can try."

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

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

Although it is only a rough and simplified prompt, Bai Wutong believes that if he gives him a little time, chemical fiber will not be too far into thousands of households.

Haidongli took over the blueprint of Bai Wutong and saw that it was a process of converting oil into a certain substance, and then condensing it into a high-grade resin-like substance, and squeezing out silk threads. drawn in a form.

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

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

Bai Wutong nodded, "Waiting for your good news."

Hai Dongli bowed and left the study.

Bai Wutong looked out the window at the falling leaves. The process of making chemical fiber is not difficult, but the difficulty is the mass production of chemical fiber equipment.

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

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

Others in the research room thought that he had come up with something again, and they were appreciated by Bai Wutong and rewarded him.

They came over to watch the fun, but the whole room smelled of oil. They wanted to ask him what he did with the oil, but remembered that he couldn't speak, and the words came back in his mouth.

Oil is flammable and explosive

The 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.

Haidongli has already owned many experimental areas by himself, and now he has another one, and everyone is very envious.

Haidongli was indifferent to other people's curiosity, and devoted himself to the experiment of refining chemical fiber~www.wuxiamtl.com~ He repeated the operation according to the steps on the drawing, and soon produced spinning fluid, but the spinning fluid's The color and feel are unsatisfactory, and even bark clothing is softer than it.

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

He also flipped through various related books, and finally, in the lesson plan that Bai Wutong gave you to make white paper, he found the relevant mixing, filtration, defoaming and other processes to conquer the spinning fluid.

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

During this period, he also made a self-made spinning machine to collect all the spinning threads quickly, so that the female workers could use them directly.

When the female worker produced the first piece of chemical fiber fabric overnight, Hai Dongli touched the soft, silky, satin-like fabric, and his hands trembled uncontrollably.

He succeeded, using black oil to develop the cloth the Empress wanted to replace cotton.

Hai Dongli danced with excitement. Others in the research room walked in. They didn't look at the fabric he was holding, but walked to several dark containers in the venue and asked, "Is this a new product you're researching?"
