Chapter 279 Wool Cleaning

Seeing that even the dean had spoken, Shi Yidao finally believed that he was really smelly, hurriedly gave Li Yan a gift, and then hurriedly left. Looking at the other person's back, Yuan Tianzhang smiled and explained: "

His Royal Highness is in a hurry. Although this stone is stingy, it is very talented on the alchemy and chemistry. Now in the chemical school, he has the highest accomplishment in the chemical school, and this time the textile material replacement research is also based on him.

Mainly. "

Yuan Tianzheng was afraid of Li Yan's sin, so he hurriedly opened a long solution for the stone, but Li Yan said with a smile: "Yuan Daochang does not have to explain, Shi Yidao concentrated on research, and forgot to take care of himself, which made the king very much admire.

! ""

Yuan Tianzhang's tone of Li Yan's tone was indeed sincerely, so he let go of it. At the moment, Li Yan came into the teaching building. As soon as he entered, Li Yan found that the smell in it was even more unpleasant, but compared to the one

The smell on Shi Dao is still worse.

It is obviously not an ordinary teaching building, and there are no teaching facilities such as podium. For example, in the classroom on the first floor, a pile of wool is stored. Although these wool seems to be similar, if you look closely, if you look closely, you can observe it, but if you look closely, you can observe it carefully, but if you look closely, you can observe it.

But the difference can be found in terms of color and fiber thickness.

Along the stairs to the second floor, the scene here surprised Li Yan. I saw a large cement pool in the middle of the big classroom on the second floor.

There was a pungent odor in it. Now Li Yan finally understands the source of the smell of the stone.

Around the large cement pond, there are more than a dozen small cement pools. Next to each cement pool, some students are dressed up. Some of them hold rude wooden sticks in their hands.

Stir stirring, and some people pick out some wool on the ground, then throw them into various cement pools, and at the same time, what is recorded on the book next to the book.

Looking at the influence in front of them, Li Yan did not go in to disturb. In fact, the main two -floor was too stinky, especially when those apprentices stirred in the cement pool, the pungent smell was even more likely

vomit.

"His Royal Highness, now the textile factory uses cotton as a raw material for textile, but because of the limited time, the cotton output is insufficient. To this end, we want to use other materials instead of cotton. After many screening

High wool instead, but if you want to use wool textile, you have to solve the first problem, that is, the problem of cleaning of wool! "Yuan Tianzhang pointed at the busy students inside introduced.

"Cleaning, what's the difficulty?" Li Yan stunned after hearing it. He knew that the wool textiles of later generations were very common, but in the era of Datang, the wool can only be made at most, thick and heavy wool felt.

Taking wool as a textile material, the key reasons in which he had not come and asked.

"His Royal Highness knows what the reason why wool cannot become cotton -like textile materials is cleaning. Because the wool is long on the sheep, it is contaminated with a large amount of sediment.

In particular, the oil in it, stick a large amount of sediment to the wool, and make the wool into hard pieces. If you do not find a way to remove the fat on the wool, there is no way to textile at all. "Yuan Tianzhang opened the way.

"Oh, so that's it. No wonder the barbarians on the grassland can only use wool to make heavy wool felt." Li Min said to himself after hearing this. In fact, the nomads on the grassland mainly use a large amount of sheepskin to make war with the Central Plains.

In commercial exchange, things like wool are just like garbage. Except for a small amount that is made into wool felt, the rest can only be thrown away.

While they were talking, the First Chief Shi who had gone to clean up just now finally came back. However, when Li Min saw the First Chief Shi again, he was immediately stunned. He saw the clean and groomed First Chief Shi, who was about thirty years old.

, the one with a face as white as jade,

Three strands of long beard fluttered under his chin, and he looked extremely handsome. Although the Taoist robe he was wearing was still very shabby, it was at least much cleaner. From a distance, he did look a bit like a Taoist immortal, which was completely different from the sloppy image before.

A world of difference.

After Shi Daochang greeted Li Min again, he began to explain the whole process of hair washing to Li Min in detail. In fact, Li Min didn't care much about the process. After all, he didn't know much about these things. What he valued most was the result.

, is whether the cleaned wool can meet the textile requirements, and what is the cost of such cleaning, and whether it has commercial value? These are what he is most concerned about.

However, although Li Min was not interested, he still pretended to be listening attentively. Although he couldn't understand most of them, he could understand some of the basic principles. It was nothing more than controlling the temperature and stirring speed in alkaline water.

To remove the grease from the wool, and there are different processing methods for different types of wool. However, these detailed processing procedures made his mind confused.

Finally, they endured the stench and listened to Shi Yiyi Chang explain the detailed process. Finally, they arrived at the third floor, where the stench was much lighter. Shi Yiyi Long pointed at a row of shelves placed against the wall and said: "

Your Highness, please see, this is our experimental sample display room, we will store the samples from each experiment here!"

As Chief Shi Yi spoke, he walked over and picked up a small glass bottle from the shelf. There was a ball of soft and yellowish wool in the bottle. On the shelf behind Shi Yi, there were probably hundreds of such bottles in total.

And Li Min and others were very shocked when they looked at the glass bottles. They didn't expect that a small washing process would require people like Shi Yi to conduct hundreds of experiments. This sounds amazing.

I can't believe it, but fortunately, they finally succeeded.

At this time, I saw Shi Yiyi walked to the end of the shelf, picked up the bottom bottle, then walked to Li Min, pointed at the soft and white wool in the bottle and said with a smile: "Your Highness, please look, this is our final process

Although the wool sample obtained is not perfect yet, it can be used as textile material!"

Li Min also took the glass bottle with some excitement, gently opened the lid and took out the wool inside, then took out a strand and rubbed it on his hands. He found that the fiber of wool was thicker than cotton fiber, but it was used as a spinning material.

Still no problem.

"Okay, Stone Road is long. Wool is indeed an excellent textile material, but what about the cost of washing wool? If it is too expensive, it may not be cost-effective!" Li Min praised first, and then impatiently said

Ask him the question he cares about most.

"His Royal Highness is relieved. The various materials used in this hair washing process are very ordinary, and the students below are also optimizing the hair washing process to strive to use the least materials to wash the most wool, so the cost is extremely low, but the cost is the cost, but this cost, but this cost is

The price of the acquisition of wool is not calculated. After all, although the wool is not valuable, if it is a large number of acquisitions, the grassland tribe of the wool will definitely raise the price. "

Think of it.

"Oh, don't worry about this long time, this king will handle it, you just need to make the entire hair washing process." Li Yan said excitedly, but then he thought of it and hurriedly asked: "By the way

Can you already apply for this patent of hair washing? "

"His Royal Highness, we have already applied for!" Shi said with a smile, patent rights are a good thing. They can live with patents in the future.

"Okay, now I give you the two choices. The first is that I will get 200,000, buy out your patent at one time.

Which one do you choose? "Li Yan said very well, even if it was placed in the present, it was not a decimal. It was almost enough to build another college.

When I heard that Li Yan was willing to come up with 200,000 to buy this patent, Yuan Tianzhang and Shi Yidao were all exposed, or that sentence, their Taoist college is still in the start -up stage, although Li Yan pays for construction to build

The college of Taoism, and there is still a year of maintenance costs, but these costs are only enough to maintain. If you want to do something else in the college, you can't squeeze it at all.

For example, the study of this cleaning wool made by Shi Tao is not a lot of money, but Yuan Tianzhang is still difficult to take out. To this end, Shi Yizheng almost tried to do everything, and even his own private property has become sold.

Even the robe on the body is not worth changing, which shows to what extent the distress.

"His Royal Highness, we choose the first one, sell the patent to you at one time!" Shi Yidao discussed with Yuan Tianzhang for a moment, and immediately made a decision. Although they also knew that the patent fee could get greater profits,

But in this kind of love, they need laughing money for research in various aspects.

"Okay, happy. In the afternoon, I ordered someone to send the checks of Datang Bank. You can go to exchange at any time!" Li Yan was also happy. He had known that Yuan Tianzhang would choose to pay at one time.

After acquiring the patent right of wool cleaning, Li Yan then visited several research projects, such as a new type of pine leather -related pine leather nitrogen, and the use of wool fat after washing.

The research is successful, and Li Yan also gives the corresponding acquisition price according to the size of the business prospects. However, the business prospects of these projects cannot be compared with wool textiles, so the price is not too high.

After visiting the college, Yuan Tianzhang took Li Yan to his residence in the college. In addition to him, Li Chunfeng sat with him. As for the long stone, he went back to bring the students to improve the hair washing technology.

However, after Li Yan just sat down and made tea, he suddenly turned to Li Chunfeng and laughed: "Brother Chunfeng, Yuan Daochang's chemical school has finished the visit. Now should you take it out of the new thing you have studied?"
