The dyeing mill is located next to the drying field, covering a large area, the building materials are mainly bamboo, in addition to the four dyeing ponds, there is also the shelf composed of bamboo poles, the main line is used for drying cloth.

It is worth mentioning that a new material is used in the dyeing pool, which is a limestone fired adhesive taken by Lin Haoran from the edge of the village, followed by sarsafrost and pebbles to form a square pool.

The most developed textile industry in the whole Ming Dynasty is undoubtedly in Jiangsu and Zhejiang, where the textile flourishes, becoming the richest region in the country, and it is also the most serious area now.

It's just that the dyeing process is a cherished thing that each family cherishes, and it won't spread at all. Not to mention a backward place like western Guangdong, even Guangzhou Prefecture does not have a few dyeing workshops, and even if there is, it cannot be compared with Jiangsu and Zhejiang.

Lin Haoran is now announcing to everyone that he can dye cloth, which is indeed a word that many people will not believe, Gu Qingfeng directly put his suspicion on his face, after all, it is not illegal to say big things in this era, and this dare to bet on five cents is bragging.

"Get things in, I'll open the eyes of these two brothers today!"

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

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

Da Biao led a few people to move the dye and white cotton cloth into it, and began the pre-work of dyeing the cloth.

"What is this fire for?"

Zhao Dongcheng watched Ah Niu put the firewood into the stove under the dyeing pond, and asked suspiciously.

He had always thought that the dyeing pool was just a pool, but he did not expect that there would be a stove underneath, and that he would have to make a fire underneath, which surprised him.

"Is your family really in the cloth business?" Gu Qingfeng glanced at him suspiciously.

"That's right!" Zhao Dongcheng nodded very seriously, as if he didn't hear the irony in his words.

Gu Qingfeng patted his head helplessly, and explained, this is used to boil water.

"It's not called boiling water, it's about controlling the water temperature!"

Lin Haoran was mixing the dye, and he glanced at him angrily.

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

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

For this reason, Lin Haoran found purple cabbage, squeezed its juice on paper, and then dried him to get a PH reagent that should not appear in this era. In this alone, he has defeated many dyers of this era.

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

It's just that as a modern person, he still has some advantages, and life has given him the concept of Celsius. The water in the bathing room is about 30 degrees Celsius, the water in the hot springs reaches 50 degrees Celsius, the sauna is above 70 degrees Celsius, and the woman is 180 degrees Celsius.

Of course, there is also an indispensable formula for dyeing cloth, which has been successfully solved by the memory in his mind and the experiments of some time ago.

While Ah Niu slowly raised the temperature of the water, Lin Haoran began to put down the dye. Due to the masking effect of the color and the chemical reaction, the addition of different dyes should be carried out according to the law.

"The dye can be green first and then black, but not black and then green!"

This is a simple record from "Huainanzi", which talks about the color to be in order, if you put black material first and then green material, then this is a wrong method.

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

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

The temperature control is relatively simple, add water if it is too hot, and continue to add firewood if it is too cold.

"Put the cloth!"

With his order, a piece of cotton cloth was soaked into the dye pool, and the originally plain white cotton cloth was slowly dyed blue.

Have you ever been infected?

Everyone looked at the cotton cloth in the pool, but they couldn't see it, after all, anything they put in the dye pool now will look black.

"Lift!"

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

I got it!

Zhao Dongcheng looked at the cloth that was scooped up, and his eyes burst out with joy, because the white cotton cloth turned blue.

Really stained?

Gu Qingfeng looked at the cloth that was scooped up, but his eyes were stunned, he didn't expect this person to really succeed.

To the surprise of both of them, the cotton cloth 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 of this dyeing cloth is undoubtedly to be dried, and it is definitely not washed now, then it is still dyed a fart!

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

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

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

Is that okay?

Gu Qingfeng once went to the dyeing workshop for reference, but he didn't have this one.

Just seeing this, he was already shocked. Fang Cai's cloth was really dyed with color, and when it was thrown into this salt water pool, the pool was still clear, proving that this color was really dyed, and it was dyed very firmly.

"Hanging cloth!"

With Lin Haoran's order, a sturdy 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, and the cloth was hung high on the bamboo frame.

"Huh? Dyeed so quickly? ”

Gu Qingfeng watched the cloth hang up and looked at him incredulously.

He saw others dyeing cloth in Guangzhou Mansion, and they still lacked this salt water pool, but it took almost an hour to dye a piece of cloth, and it turned out that this person had less than one-third of the time.

"The little brother has really seen the eye!"

Zhao Dongcheng made another long gesture towards him, and he was so impressed that he threw himself to the ground.

Lin Haoran threw the melon peel away, and then said proudly: "It's a trivial matter, how difficult do you think!" ”

How can it be!

Gu Qingfeng stepped forward and reached out and touched the hanging cloth again, and was immediately shocked again, and found that this was actually a top grade. Even if he is as arrogant as him, he has to be impressed at this moment.

"Alright, let's discuss some business, please here!" Lin Haoran beckoned to them and led them towards the door.

"What's the matter?" When the two of them heard him say solemnly, they couldn't help but follow and ask.

"Tiger girl, where are you playing again, come here!" Lin Haoran beckoned to the little girl who came back from the entrance of the village, and then turned back to the two of them and said seriously: "My sister's birthday has arrived, should you give her a gift?" ”
