Chapter 129 Two-tailed scorpion makes straw cotton

Sun Xin looked at the sulfuric acid and caustic soda made by the father and son. He couldn't help patting Li Zhi and his two sons on the shoulders and said, "You have worked really hard."

Jie Bao also stood forward with a smile. Li Zhi and the other three had done a great job in making sulfuric acid and caustic soda, and a series of preparations and coordination were also entrusted to him by Sun Xin.

Sun Xin gently pushed Jie Bao's shoulder and said, "You're not bad either."

Jie Bao touched his shoulders and laughed. Although he had a lively mind, he was still just a kid in his early teens, so he took the Master's praise very seriously.

Today, several leaders and stewards of Sunjiazhuang held a temporary meeting at Sun Xin's invitation, and at this time they all came to Sunjiazhuang's pharmaceutical workshop.

The sulfuric acid and caustic soda made by Sun Xin had repeatedly warned about the danger, and Li Zhi and his two adopted sons were injured. Everyone present knew how powerful this thing was, so there was no rush to get involved.

When Sun Xin opened those things, Zou Run was a little confused and said: "Master, can you make the cotton you mentioned with just these two things?"

The other leaders were also at a loss, unable to imagine how the cotton should be made.

Sun Xin smiled and said to Jie Bao: "I will try it myself."

In the past few days, Li Zhi has also devoted himself to the production of straw cotton. He has done it with his own hands and understood the principles, so he also took the initiative: "Master, I will also come to help."

"Two and eight cents per catty."

Because the strains were cultivated at the foot of Dengyun Mountain, whatever was collected was used, so the mushrooms cultivated in that batch were actually chanterelles that were sold at a very low price in the previous life. The yield of that thing was the lowest at the foot of Dengyun Mountain. As for the former market

The main cultivated mushrooms are shiitake mushrooms and Agaricus bisporus, which are wild mushrooms that are not found in the south. In those days, anyone who wanted to find Jiebao could find them.

Then throw the thing back into a small bamboo basket, lift it into a retting pond, soak it, use a wooden spoon to stir up running water to wash away the residual acid on the surface, and then put it in an oven to dry.

That set of operations are all methods we have figured out. According to Li Zhi's experience, when the water in the copper basin is cooled to that extent, the temperature of the liquid in the porcelain jar is about 40 degrees as the master said.

Zou Run picked up a wooden stick and stood nearby, carefully stirring the straw in the porcelain vat.

Jie Bao used that method to produce wheat straw fiber in his previous life. Because the cost of cotton in the previous life was too high, coupled with the cost of processing the industrial waste used to produce wheat straw fiber, the wheat straw fiber was completely uncompetitive in the market in the previous life. However,

I would have thought that in those days, the development cost of wheat straw fiber was actually higher than that of spinning yarn.

Zhiqiao nodded and asked us to continue. Several pharmacists added more fire to the porcelain vat. At the same time, Li Zhi and Li Zi slowly poured a few dustpan-broken straws into the porcelain vat.

Everyone's eyes lit up when they heard this. It was even higher than the price of reed flowers in the market. As long as seven or eight kilograms were bought, it would be enough to fill a very warm piece of clothing. Even the poor outside Dengzhou City spent more than half of it.

I can afford it with a month’s salary.

For more than half a month, Sun Xin and Xie Zhen were busy in the greenhouse.

The instant the dilute sulfuric acid is poured up, the acid-base neutralization produces a small amount of cold, and the column of straw slowly becomes smoky.

When all the straws were stirred out of the water and fully soaked, Li Zhi and Zou Run breathed a sigh of relief.

Zou Yuan clicked his tongue and exclaimed: "We can always produce eight hundred kilograms of wheat straw per acre of ground every year. If we all do this, wouldn't it be like a cornucopia?"

As soon as the straw encounters strong alkaline water, it will stop ablation and become soft.

The strains they used were wild strains collected from the foot of Dengyun Mountain, and the survival rate was not very low. However, within half a month, Xie Zhen and her nephew successfully grew a plant under the wheat straw bacteria bag.

Qiaolang’s first batch of artificially cultivated bacteria.

Before Li Zhi and Zou Run started, Jie Bao took Xiaojia to see the research results of Jie Zhen and Sun Xin. Today, Jie Bao took all the village leaders to see the wheat straw cotton product.

Production technology.

On one side, the liquid in the cooling cylinder was added, and a large copper basin was placed on the surface of the liquid, with half a basin filled with hot water.

When Tao Zongwang touched the soft fiber wadding, he was pleasantly surprised and said: "Master, what a bad thing. It feels softer than linen yarn. As long as you find a few women to spin it on a spinning wheel, it can't be sold as linen thread, nor can it be woven into linen cloth."

Okay, even if it’s hammered like that, it can’t be used as a filler for winter clothes. How much does it cost to produce that thing?”

Seeing that we were in danger of reaching that step, Jie Bao breathed a sigh of relief and asked Xiaojia to go aside to rest first. The soaking process would take half an hour. Before half an hour of tea, the straw in the porcelain jar was gone.

After being soaked by caustic soda, Zhi Qiao and Li Zhi took the straw out of the porcelain jar, and then added prepared dilute sulfuric acid to the straw to neutralize it.

Just like growing greenhouse vegetables requires light-transmitting glass, growing edible fungi does not require sunlight. It only needs to provide enough nutrients, temperature and humidity, so it was impossible to grow edible fungi in those days.

It took two hours, and when the first scale was put down, seventy kilograms of straw fiber came out of eighty kilograms of straw.

The fiber length of the straw fiber produced is generally eight to eight centimeters, which is very different from the fiber length of linen yarn. The barley straw fiber was not smooth in previous generations, so it must be blended with cotton or chemical fiber to form fiber threads.

But in those days

It was not considered a very soft material, and it needed such simple processing. Jie Bao asked two dealers to beat the wheat straw fibers together. Very slowly, the wet wheat straw fibers became entangled together and turned into one.

The cotton wool has a special look.

We all know the power of the caustic soda water before operating it several times. The thing is cooled to about 40 degrees, and big bubbles bubble up. During the operation, if the caustic soda water splashes under the skin, it can cause a lot of damage.

The entire skin was burned alive.

After pouring all the dilute sulfuric acid and stirring it for a while, the acid and alkali have been neutralized. This column of straw is not completely broken into rotten fibers.

White smoke quickly rose from the alkaline water in the porcelain vat, and the temperature gradually rose and lowered until the surface of the liquid boiled slightly. Then the two of them brought up the copper basin Daxin from under the water. Li Zhi took a piece of vermicelli with bubbles and put it on it.

He stepped out of the copper basin, then took off his gloves and pinched his pulse to count. The pulse beat a hundred or so, and the vermicelli was slightly softened. So Li Zhi nodded, looked at Zhiqiao and said, "Master, the temperature is enough."

Already."

The main reason is that the wheat straw fiber burned with a weak alkali is softer than the linen yarn. Since the weak alkali step is to select raw materials, it also requires money to treat the wastewater.

Zhiqiao and Li Zhi carelessly put on their suede leather gloves and aprons, put on a mask that could not prevent liquid from splashing down their faces, and then carefully poured the prepared soda ash into the

It is diluted in a small porcelain vat, and there is no dealer to light the fire and cool it on the porcelain vat.

The pharmacist brought the prepared straw.

All these straws had been cut into two-inch-long pieces, and each straw was broken into seven parts. Li Zhi went to Tang Long to get a sleeve knife, stuffed the straw from one end, and cut it from the other side.

The straw can be broken into seven pieces by pulling it.
