The dyeing workshop is located next to the grain drying field. It occupies a large area and the building materials are mainly bamboo. In addition to the four dyeing pools, there is also a shelf made of bamboo poles. The main line is used for drying cloth.

It is worth mentioning that the dyeing pool uses a new material, which is limestone that Lin Haoran took from the village and fired adhesive, followed by root beer and pebbles to form a square pool.

The most developed textile industry in the entire Ming Dynasty was undoubtedly in Jiangsu and Zhejiang, which prospered from textiles and became the richest region in the country. It is also the area where the Japanese invasion is most serious.

It's just that the dyeing technology is something that each family treasures, and it will not spread at all. Let alone a backward place like western Guangdong, even Guangzhou Prefecture does not have a few dyeing houses, and even if it does, it cannot compare with Jiangsu and Zhejiang.

Lin Haoran is now claiming to everyone that he can dye cloth. This is indeed something that many people will not believe. Gu Qingfeng directly puts his doubts on his face. After all, it is not illegal to tell lies in this era. I dare to bet five cents on it.

Money is bragging about the New Year.

"Get the things in, and I will open the eyes of these two brothers today!"

Lin Haoran waved confidently, and then led the two of them into the newly built dyeing workshop.

The layout inside the dyeing workshop is very simple, with four rectangular dyeing pools, a cloth drying rack and a warehouse.

Dabiao led a few people to move the dye and white cotton cloth inside, and then began the preliminary work of dyeing the cloth.

"What's the fire for?"

Zhao Dongcheng asked in confusion as he watched A Niu put the firewood into the stove under the dye pond.

He always thought that the Dyeing Pond was just a pond, but he did not expect that there would be a stove underneath and a fire would have to be lit underneath, which surprised him deeply.

"Your family is really in the cloth business?" Gu Qingfeng looked at him suspiciously.

"Yes!" Zhao Dongcheng nodded seriously, as if he didn't hear the sarcasm in his words.

Gu Qingfeng patted his head helplessly and explained that it was used to boil water.

"This isn't called boiling water, it's called controlling the water temperature, okay?"

Lin Haoran was mixing the dye and rolled his eyes at him angrily.

In the entire dyeing process, there are actually only two most important events: one is to control the acidity and alkalinity, and the other is to control the temperature of the dye bath.

As long as these two tasks are done well, the color fastness of the dyed fabric can reach level 2-3. Naturally, this color fastness cannot be compared with modern fabrics, but it is still no problem to become the top product of this era.

.

To this end, Lin Haoran found purple cabbage, squeezed its juice onto paper, and then dried it in the sun to obtain a pH reagent that should not appear in this era. With this alone, he has defeated many dyes in this era.

Master cloth.

As for the temperature issue, he didn't have the ability to make a mercury thermometer.

But as a modern man, he still has some advantages. He has the concept of degrees Celsius in life. The water in the bath room is about 30 degrees Celsius, the water in the hot spring will reach 50 degrees Celsius, and the sauna will be above 70 degrees Celsius. It takes a long time to find a woman.

One hundred and eighty degrees.

Of course, there is also an indispensable dyeing formula. After remembering this in his mind and doing experiments some time ago, he has successfully solved this problem.

While A Niu slowly raised the temperature of the water, Lin Haoran began to put down the dye. Due to the masking effect of color and chemical reactions, the addition of different dyes must be carried out according to rules.

"It's OK to dye it green first and then black, but it's not allowed to be black first and then green!"

This is a simple record from "Huainanzi". It talks about colors in order. If you put the black material first and then the green material, then this is a wrong method.

Of course, the actual situation is more complicated than here, otherwise Lin Haoran would not have experimented for so long to get the formula.

After putting down the dyes one after another, Lin Haoran began to pay attention to controlling the acidity, alkalinity and temperature in the dye pool.

The temperature control is relatively simple. If it is too hot, add water; if it is too cool, continue to add firewood.

"Release the cloth!"

Following his order, a piece of cotton cloth was soaked in the dyeing pool, and the originally white cotton cloth was slowly dyed blue.

Have you ever contracted it?

When everyone looks at the cotton cloth in the pool, they can't actually see it. After all, whatever is put into the dye pool now will look dark.

"Close the cloth!"

Lin Haoran was standing nearby eating melon, as if everything had nothing to do with him.

Infected!

Zhao Dongcheng looked at the picked up cloth, his eyes bursting with joy because the white cotton turned blue.

Really infected?

Gu Qingfeng looked at the cloth that was picked up, but his eyes were stunned for a while. He didn't expect that this man really succeeded.

What surprised the two of them was that the cotton cloth they picked up was not hung up, but was thrown into a pool.

What's going on?

Gu Qingfeng and Zhao Dongcheng were both slightly stunned for a moment, and looked at Lin Haoran in confusion. The next step for dyeing the cloth is undoubtedly to dry it in the sun. If you don't wash it now, it will still be dyed!

"This is a salt water pool, used to fix the color!"

Lin Haoran took a bite of the melon meat and explained vaguely.

Salt water pool, this is the last step in dyeing. The color of the cotton cloth will be completely fixed here, and there will be no problems such as fading in the future. This is also one of the modulus standards of good cloth.

Is this okay?

Gu Qingfeng once went to the dyeing workshop to refer to it, but there was no such item.

Just seeing this, he was already shocked. The cloth just now was really dyed, and when he was thrown into the salt water pool, the water was still clear and clear, which proved that the cloth was really dyed, and it was also dyed.

Very strong.

"Hanging cloth!"

Following Lin Haoran's order, a strong young man tied one end of the rope to the cloth, and then asked the person at the other end to pull the other end of the rope. The cloth was hung high on the bamboo shelf.

"Ah? You dyed it so quickly?"

Gu Qingfeng watched the cloth hanging and looked at him in disbelief.

He had seen others dyeing cloth in Guangzhou Prefecture. They still lacked the salt water pool, but it took almost an hour to dye a piece of cloth. As a result, this person's time was less than one-third.

"My little brother has indeed seen something new!"

Zhao Dongcheng bowed to him again, admiring him with admiration.

Lin Haoran threw the melon rind away and said proudly: "It's such a small thing, how difficult do you think it is!"

How is that possible!

Gu Qingfeng stepped forward and reached out to touch the hanging cloth again. He was immediately surprised to find that it was actually a top grade cloth. Even someone as arrogant as him had to be convinced at this moment.

"Okay, let's discuss some business, please come this way!" Lin Haoran waved to them and led them towards the door.

"What's the matter?" After hearing his serious words, the two of them couldn't help but follow him and ask.

"Hu Niu, where are you playing again? Come here quickly!" Lin Haoran waved to the little girl who came back from the village entrance, then turned back to the two of them and said seriously: "My sister's birthday is here, shouldn't you give me some gifts?"
