Since Zhang Ran sent Li Chong to Canguan before, no one in charge of the workshop garden, and other assistants lacked enough prestige to coordinate the matters, Zhang Ran could only take care of this matter himself.

First, Zhang Ran ordered the assistant officials to bring this group of new weavers to the southeast of the workshop garden. This is the living and residential area designated by Zhang Ran, and most of the houses and other buildings have been built recently.

Moreover, almost every row of houses has more than two flue channels connected, so even in winter, these houses are very warm and their living conditions are much better than other places.

In fact, Zhang Ran planned the layout of the workshop garden very early. He basically built it according to the industrial park common in later generations. Therefore, work areas, living areas, office areas, canteens, etc. are basically available, and even the toilets were repaired a lot early. There was no need to worry that the craftsmen who settled here would have no place to live.

However, what Zhang Ran did not expect was that most of these new weavers were female workers, and they were also younger women... For this reason, Zhang Ran had to set up an area for these female weavers as their living and working areas, and strictly prohibited other male workers from entering to avoid causing chaos.

Then, Zhang Ran asked the strong men to transport all the batch of wool brought by Zheng Jin to the newly built warehouse for temporary storage to avoid stacking in the open air and affecting the quality of the wool under the wind and sun.

He has been busy for nearly an hour. When Zhang Ran handled these matters almost the same, the chief clerk Li Chong also brought someone back from Canguan.

So, Zhang Ran ordered Li Chong to take over the work of the workshop garden, and he took the twenty weavers and dyers selected by Zheng Jin and the twenty craftsmen who were proficient in refining and silk reeling craftsmen brought back from the Cannabis Temple to rush to the Science and Technology Park of Jianzhang Palace to prepare for experimenting with wool garments.

...

If you want to make wool into a wool, the first thing you need to do is to clean the wool and remove its odor, then spun it into wool, and then knit the wool into wool or sweater.

Most of the wool sent by Zhao Yu to Zhang Ran were newly cut after the winter, and the newly cut wool has not been treated at all. Therefore, these wool not only smelled fishy and unpleasant, but also contained a lot of dirt such as lanolin, sheep sweat, sand, grass seeds and even sheep manure, which made it difficult to get close to.

Looking at the pile of dirty and smelly wool piled in the corner of the house, Zhang Ranqing couldn't help but stop, and covered his mouth and nose with his hands, frowned and turned to Zheng Jin and asked: "Zheng Lushi, how did you deal with these wools before? Wash them directly with clean water? Can this be washed clean?"

Hearing Zhang Ran’s inquiry, Zheng Jin bowed and replied, “Reporting to Zuo Cheng, this is exactly the case. The newly sheared wool contains a lot of dirt and grease, which needs to be washed repeatedly with water to remove impurities and odors. Generally speaking, if you want to clean the wool, it takes at least four or five times!”

"Well~" Zhang Ran nodded slightly and pondered: "Then try it according to your method first! Go and have someone get a few more basins of clean well water and wash the wool before talking about it!"

"Here~" Zheng Jin bowed to accept the order, and then took the people in person to prepare the well water as Zhang Ran told him.

Although Zhang Ran knew that lime water has the effect of removing dirt and grease, it can be used to clean the grease and odor in wool, he really didn't have a deep understanding of the specific steps and details of washing wool.

Therefore, Zhang Ran thought it would be better to take a look at how Zheng Jin and the others had originally cleaned the wool, and try to use this as a reference to improve it after fully understanding the steps of wool cleaning.

About five minutes later, Zheng Jin brought more than a dozen craftsmen, each carrying a large basin of clear water back into the house.

Then, under Zhang Ran's gaze, Zheng Jin rolled up his sleeves and took out a large ball of dirty wool from the pile of wool, put it in a wooden basin to wash, and rub it... After changing three basins of water in a row, Zheng Jin barely cleaned the wool.

A few minutes later, when Zhang Ran saw that Zheng Jin washed the wool and took it out and put it in a clean wooden basin next to him, he couldn't help but frown and asked, "Have you washed?"

"Yes!" Zheng Jin nodded, looking at Zhang Ran with some anxiety, "According to the previous treatment method in the weaving room, it will be almost done to wash to this level."

"Let me see!" Zhang Ran walked forward directly, grabbed a handful of wet wool from the wooden basin and looked carefully and observed it.

On the surface, these wools were washed very clean, and the grass seeds, sheep manure and other things were not visible at all. However, their color still looked dull, and even gave people a feeling of being gray.

Moreover, there seemed to be a lot of grease attached to the wool. It felt greasy when grasped in the hand, and it also had a smell of mutton.

"No use at all!" After checking the wool that Zheng Jin cleaned, Zhang Ran quickly came to his own conclusion.

In Zhang Ran's opinion, Zheng Jin's method of cleaning the wool completely flows to the surface, and only cleanses the impurities attached to the wool. It looks a little "clean", but in fact it is useless!

Since Zheng Jin's method was not very useful, Zhang Ran had to think of other ways. While recalling the method of wool treatment in his memory, he said to Zheng Jin and others: "Give me some hot water and get some lime powder by the way... By the way, there is also salt, take some of it!"

...

After Zheng Jin and others prepared everything as Zhang Ran told him, Zhang Ran asked someone to make some warm water and soak the washed wool in... Then, they asked everyone to pour hot water and salt into the wooden basin, melt it into salt water, and stir it evenly.

Then, according to the method of getting salt water just now, I prepared several basins of lime water as usual. I prepared to try it separately.

After soaking the wool in warm water for about ten minutes, Zhang Ran obviously saw that a layer of dirty things gradually floated in the wooden basin.

Zhang Ran ordered people to take out the wool from the wooden basin, put it in another wooden basin to clean it, and then picked up some wool again and checked it carefully.

The wool after being soaked and cleaned in warm water does not feel as oily as before, and the taste is much smaller than before, but the color does not change much, and it still looks the same.

At this time, Zheng Jin, who was standing beside him, also picked up a little wool from the wooden basin and observed it carefully... After a while, Zheng Jin couldn't help but exclaimed: "Zuo Cheng, this wool seems to be much cleaner than before, and the taste has become lighter! This is too incredible. Could it be that soaking it in warm water can remove the odor of the wool?"

Zhang Ran smiled faintly, shook his head and said, "Actually, it is not. Soaking in warm water, what is removed is the oil attached to the wool and the solidified sheep sweat salt crystal. Most of the smell of the wool comes from sheep sweat. After washing off the sheep sweat, the smell of the wool naturally becomes lighter. However, it is only a little lighter. To eliminate most of its odor, other methods are needed!"

Zheng Jin was almost out of his words when he heard the shocked expression, and he couldn't help but clasp his fists to someone with great admiration and said, "Zuo Cheng, a great talent, has really opened his eyes to his subordinates! Who would have thought that a mere basin of warm water would have such a magical effect!"

Upon hearing this, Zhang Ran couldn't help but shake his head and laughed: "This method is not as magical as you said. The principle is rather simple... Don't you think that the method of washing dishes or washing clothes with warm water is very similar to the current method of washing wool?"

"Uh!" Zheng Jin was confused, then he thought about it and suddenly realized!

After Zhang Ran reminded him, Zheng Jin realized that these two things that were originally irrelevant were actually somewhat similar.

For example, everyone knows that if you wash dishes with warm water, you can clean the greasy and greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greasy greas

So, since warm water can melt away the sweat stains on the bowls, chopsticks and clothes, it is natural to agree that it can melt away some of the sheep oil and sheep sweat on the wool... The difference is nothing more than the difficulty and the length of soaking required is different.
