Seeing that even the dean had spoken, Chief Shi Yiyi finally believed that he really stinks, saluted Li Yin hurriedly, and left in a hurry.Looking at the back of the other party, Yuan Tiangang explained with a smile: "Your Highness, although this Shi Yi is sloppy, he is extremely talented in alchemy and chemistry. Now in the School of Chemistry, his accomplishments are the only ones." He is the highest, and he is also the main focus of this textile material substitution research."

Yuan Tiangang was afraid that Li Yin would blame him, so he hurriedly explained to Master Shi, but Li Yin laughed and said, "You don't need to explain, Master Shi concentrates on research and forgets to take care of himself, which makes me very admired." !"

Seeing that Li Yin's tone of voice was sincere, Yuan Tiangang felt relieved, and immediately led Li Yin into the teaching building.As soon as he entered, Li Yin found that the smell inside was even more unpleasant, but it was still worse than the smell of that long Shi Yiyi.

This is obviously not an ordinary teaching building, and there are no teaching facilities such as podiums. For example, in the classrooms on the first floor, piles of wool are stored. Although these wools seem to be similar, But if you observe carefully, you can find the difference in color and fiber thickness.

Going up the stairs to the second floor, Li Yin was taken aback by the sight here. In the large classroom on the second floor, there was a large cement pool in the middle, which was filled with a kind of off-white liquid, and there was a pungent smell coming out of the liquid, now Li Yin finally understood the source of that stench on the body of Shi Yiyi.Capital Datang 279

Around this big cement pool, there are more than a dozen small cement pools. Beside each cement pool, there are some people dressed as students busy, some of them are holding thick wooden sticks, standing in the cement pool. They stopped stirring, and some people picked out some wool on the ground, and then threw them into various cement pools, and at the same time recorded something in the notebook next to it.

Seeing the impact in front of them, Li Yin and the others didn't go in to disturb them. In fact, the main reason was that the second floor was really smelly, especially when the apprentices were stirring in the cement pool, the pungent smell was even more irritating. vomit.

"Your Highness, now the textile mills use cotton as raw material for weaving, but due to time constraints, the cotton output is insufficient. Therefore, we want to use other materials instead of cotton. High wool "wool" instead, but I want to use wool "wool" for weaving, but I have to solve the first problem, which is the problem of cleaning wool "wool!" Yuan Tiangang pointed to the busy students inside and introduced.

"Cleaning, what's so difficult about it?" Li Min was taken aback when he heard this. He knew that wool "wool" weaving was very common in later generations, but in the era of Tang Dynasty, wool "wool" could only be made into thick and heavy fabrics at best. Wool felt, no one regards wool as a textile material at all, but he never came and asked about the key reason.

"Your Highness does not know that the most important step is to clean the wool that cannot be made into a cotton-like textile material. Because the wool grows on the sheep, it is contaminated with a lot of sand. Sweat stains, grease, etc., especially the grease in it, will stick a lot of sediment to the wool, making the wool hard into lumps. If you don't want to remove the grease from the wool, it will be impossible There is no way to weave." Yuan Tiangang explained.

"Oh, so that's the case. No wonder the barbarians on the grassland can only use wool to make thick wool felt." Li Yin said to himself after hearing this.In fact, the nomads on the grassland mainly use a large amount of sheepskins for commercial exchange with the Central Plains. Things like wool are like garbage. Except for a small amount that will be made into wool felt, others can only be used. Discard.

While talking, the chief Shi Yiyi who went to clean up just now finally came back, but when Li Yin saw this chief Shi Yiyi again, he was immediately taken aback, and saw that the freshly washed Shi Yiyi was about 30 years old The one with a face as white as jade, and three strands of long beard fluttering under his jaw, looks extremely chic. Although the Taoist robe he is wearing is still very worn out, at least it is much cleaner. From a distance, he does look like a Taoist immortal. The scruffy image before is simply a world of difference.

After paying respects to Li Yin again, Chief Shi Yidao began to explain the whole process of washing "hair" to Li Yin in detail.In fact, Li Yin doesn't care much about the process. After all, he doesn't know much about these things. What he values ​​most is the result, which is whether the washed wool can meet the requirements of textiles, and what is the cost of this cleaning? No commercial value?These are what he cares most about.

However, although Li Yin is not interested, he still pretends to be listening seriously. Although most of them don't understand, he can understand the basic principles. It is nothing more than controlling the temperature and stirring speed in alkaline water. Let the grease off the wool, and there are different ways to deal with different types of wool.However, these detailed processing procedures made a mess in his mind.

After finally suppressing the stench, Master Shi Yiyi finished the detailed procedure, and finally they came to the third floor, where the stench was much weaker.I saw Shi Yiyi pointed at a row of shelves next to the wall and said: "Your Highness, please look, this is our experimental sample storage room. We will store the samples of each experiment here!"

As Shi Yidao said, he walked over to pick up a small glass bottle from the shelf, and there was a ball of soft yellowish wool in the bottle.And on the shelf behind Shi Yi, there are probably hundreds of such bottles.

And Li Yin and the others looked at the glass bottles one by one, and they were also very shocked. They didn't expect that a small "hair washing" process would make Shi Yi and others conduct hundreds of experiments. It's unbelievable, but fortunately, they finally succeeded.

At this time, I saw Shi Yiyi walked to the end of the shelf, picked up the bottom bottle, walked to Li Yin, pointed to the soft and white wool in the bottle and said with a smile: "Your Highness, please look, this is the bottle. The wool samples we got from the final process, although not perfect, can be used as textile materials!"

Li Yin 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, and found that the fibers of wool were thicker than cotton fibers, but There is no problem as a spinning material.

"Okay, Shi Yidao is long. Wool is indeed an excellent textile material, but how about the cost of washing wool? If it is too expensive, it may not be cost-effective!" Li Yin praised first, and then continued He couldn't wait to ask the question he was most concerned about.

"Don't worry, Your Highness, the various materials used in the wool-washing process are very common, and the student union below is also optimizing the wool-washing process, striving to use the least amount of materials to wash out the most wool, so the cost It is extremely low, but this cost does not include the purchase price of wool. After all, although the current wool is worthless, if it is purchased in large quantities, the grassland tribes that are rich in wool will definitely increase the price Yes." Chief Shi Yiyi is indeed a talent, and he even thought of future commercial applications.

"Hehe, you don't have to worry about this bit of stone. This king will take care of it. You just need to figure out the whole washing process." Li Yin said excitedly, but then he thought of something again, and asked hastily: " By the way, have you applied for the patent for washing "hair"?"

"His Royal Highness, we have already applied for it!" Shi Yi said with a smile, patent rights are a good thing, and their chemistry college will all rely on patent rights in the future.

"Okay, now I will give you two choices. The first is that I will pay you 20 coins to buy out your patent at one time. The second is that you retain the patent right, and those who use the patent for washing hair will pay you." Patent fee, which one do you choose?" Li Yin said proudly, 20 guan is not a small amount even if it is placed now, it is almost enough to build another Taoist academy.Capital Datang 279

Upon hearing that Li Yin was willing to spend 20 yuan to buy this patent, Yuan Tiangang and Shi Yiyi expressed joy on their faces. Again, their Taoist academy is still in its infancy, although Li Yin He paid for the construction of the Dao Academy, and there is still a year of maintenance costs, but these expenses are only enough to maintain, and if the academy wants to do other things, it simply cannot be squeezed out.

For example, the research on cleaning wool done by Mr. Shi Yidao, although the money needed is not a lot, but it is still difficult for Yuan Tiangang to get it out. They've all been sold, and it's not even worth replacing the Taoist robe on their body if it's torn. This shows the extent of the embarrassment.

"Your Highness, we will choose the first one and sell the patent to you in one go!" Shi Yiyichang discussed with Yuan Tiangang for a while, and immediately made a decision, although they also knew that collecting patent fees would get more benefits. Profit, but under the current situation, they need money to do various researches.

"Okay, happy, I will order someone to deliver the Datang Bank's check in the afternoon, and you can exchange it at any time!" Li Yin also said happily, he had long known that Yuan Tiangang would choose to pay in one lump sum first.

After acquiring the patent right for wool washing, Li Yin then visited several projects under research, such as a new method of tanning sheepskin related to washing wool, and collecting wool after washing Some of these projects have been successfully researched, such as the utilization of fat, etc., and Li Yin also gave corresponding purchase prices according to the size of the commercial prospects. However, the commercial prospects of these projects cannot be compared with woolen textiles, so the price Neither is too high.

After visiting the College of Chemistry, Yuan Tiangang took Li Min to his residence in the college. Apart from him, he was accompanied by Li Chunfeng. As for that Chief Shi Yiyi, he had already gone back to take the students to perfect the washing process. .

However, just after Li Yin sat down and had a sip of tea, he suddenly turned to Li Chunfeng and said with a smile: "Brother Chunfeng, Daoist Yuan's chemistry school is over, should it be time to take a look at the new things you have researched?" continued)
