If it is placed in normal times, the straight man Ning Bei will definitely not be able to say anything good in his mouth.

It's good-looking, beautiful or something.

Although it is also a compliment to Qin Yangyue, it will definitely not make Qin Yangyue very happy.

These words of praise are too simple!

But this time, Ningbei has learned well!

Looking at the good words in the live broadcast room, Ningbei will boast about anything!

Qin Yangyue giggled, and those who didn't know thought it was Brother Kun Chengjing!

Qin Yangyue, who was in a good mood, went to the fitting room to change into another dress, and Ning Bei also took the time to ask the audience a question that he thought was very profound.

"What is a Jacquard Machine?"

Although only one person mentioned this machine, Ningbei, who had never forgotten it, still wrote it down.

Although he is also a graduate of a prestigious university, he has a specialization in the so-called art industry, and he didn't study these things in college, so he really didn't know what this thing was.

But just by listening to the name, Ning Bei can also guess that this is a machine that can print on clothes.

Ning Bei vaguely felt that this machine was of great use!

"What the hell?"

"I can't do it!"

"It's familiar, I think I've heard of it somewhere, but I forgot."

"Looks like it's supposed to be a color or a pattern on the cloth, right?"

When hearing about the Jacquard machine, most of the audience was also confused.

Of course, none of this is a problem.

There are tens of thousands of viewers in the live broadcast room, even if only one percent of the audience knows, it is enough.

Soon, knowledgeable viewers began to introduce this machine to Ningbei.

"The Jacquard machine, which uses pre-punched cards to control the weaving pattern of the fabric, is faster than the old handmade jacquard machine, I don't know how many times!"

"That's not the point, the point is that the Jacquard machine can print patterns!"

"Didn't the ancients like bells and whistles? Let's not use the color, just the pattern! Isn't that just crushing them completely? Isn't this a big sum of money! ”

"The speed of Jenny's spinning machine is already several times that of ordinary spinning machines, plus a Jacquard machine, the anchor directly monopolizes the cloth business of the Tang Dynasty, okay!"

“……”

Looking at everyone's explanations, Ning Bei probably understood the meaning of the existence of the Jacquard machine!

Before that, I would like to mention the principle of weaving.

First of all, the yarn of weaving is divided into warp and weft, the vertical is the warp, and the horizontal is the weft.

The principle of weaving cloth is to interweave the warp and weft threads with each other to finally form the cloth.

The warp yarns are divided into two rows, and the number of warp threads is sorted according to the size of the cloth to be weaved, while the weft yarn has only one.

Lift a row of warp yarns, after the weft yarn passes through the first row of warp yarns, lift another row of warp yarns and lift it, and the weft yarn passes through this row of warp yarns again!

This back and forth is a process of weaving.

By repeating this action repeatedly, you can make a strong and durable cloth.

If you want to weave only one solid color cloth, then you can use a shuttle loom to weave it.

Just choose threads of the same color for warp and weft.

However, if you want to weave different colors of cloth, then you can't do without a jacquard machine.

If you want black cloth with a white pattern, the black cloth can be directly used with the warp, and when it comes to the area where the white pattern is to be woven, then a person needs to stand on the jacquard machine, carry the white warp yarns by hand, and when you want to weave the white pattern, you can lift the red warp yarn with your hand so that the weft can pass through.

In Wang Yi's "Machine Woman Fu" of the Eastern Han Dynasty, he used "a slender and quiet woman, the meridians, shaking and multi-ronged, and pitching and living" to describe the scene of the weaver and the jacquard worker cooperating to manipulate the jacquard machine.

The result is a white pattern.

This is the earliest manual jacquard machine, but this manual operation method is too troublesome, and you have to find the white warp one by one, which is time-consuming and laborious.

Moreover, it is easy to cause the appearance of the same pattern on the cloth, which is not quite the same.

There will inevitably be some errors in manual operation.

In addition to this method, the ancient people also wanted to add patterns to the king's clothes, so they could also use embroidery.

For example, the five-clawed golden dragon on the emperor's dragon robe, the python on the prince's purple robe, and the birds on the courtier's official uniform.

This is something that can't be done manually!

Although this will be more three-dimensional, it will also take a long time and be more expensive!

Naturally, the rich didn't care, and the common people couldn't afford to buy cloth with patterns.

Therefore, the common people in ancient times wore solid clothes, especially white clothes.

Because there is no need to dye any color, white clothes are the cheapest.

There is a sentence in "The Burrow", "There is a great deal of Confucianism in talking and laughing, and there is no white in communication." ’

Among them, Bai Ding is the common people.

Ordinary people can only afford white cloth.

The really poor can't even afford white cloth......

As for the working principle of the Jacquard machine, the pre-punched cards are used to control the color and pattern of the fabric!

In layman's terms, it is to prepare a card, and then punch holes on it according to the pattern you want to weave, and a weaving process corresponds to a punched card.

In the process of weaving, how many black lines and how many white lines need to be lifted, and the steel pairs of these black and white lines need to be punched.

In this way, the punched cards will replace manual search and screening, and the required threads will be lifted accurately and quickly.

In addition, the punched card can be used repeatedly, and if you use a steel plate as a card, the punched card will not be broken, and you can always weave the cloth with this pattern.

As long as you don't feel that this pattern is outdated.

Moreover, the patterns woven by the Jacquard machine are also relatively uniform.

The main thing is that the Jacquard machine can take advantage of the steam engine!

When used in conjunction with a steam engine, it is more than a thousand times faster than an ordinary jacquard machine!

This...... It's all white silver!

For a while, Ningbei fell into fantasy.

If this is the logo of the entire Lv Lemon, and then popularize the copyright fee, then he will have to earn to death!

At this moment, the audience asked new questions.

"Brother Bei, you can't just have a machine! We still have to start with the raw materials! ”

"If you want to say that the best textile material for natural fibers, it has to be cotton! The production is not small, and it is very versatile! Otherwise, you can make clothes, and you can also make quilts and jackets. ”

"In the Tang Dynasty, there were already merchants importing cotton from the Western Regions to the Central Plains, and Brother Bei, you only need to contract a large piece of land and plant cotton."

"I remember that cotton was only widely used in the Song Dynasty, right? Let's directly advance a few hundred years in advance, so that the people of the Tang Dynasty can understand what warmth is! ”

"It is indeed necessary to plant more cotton and make a quilt to keep warm and invincible!"

Ning Bei nodded, and then wrote down the cotton on his clothes.

"Liangshu Gaochang Biography" records: its land has "grass, really like a cocoon, the cocoon silk like fine silk, named white stacks." ”

'White stacks' are cotton.

Although cotton can keep warm, many people will not choose to grow it because it has no edible value.

It was not until the Song Dynasty that far-sighted merchants cultivated cotton and used it.

Cotton is very warm and can be converted into a lot of money as long as it can withstand time.

Of course, there are two prerequisites for this.

One is that there is a lot of land, and the other is to find cotton seeds.

As long as you can do both, you don't have to worry about anything else.

At this point, the audience came up with another natural material.

"Have you forgotten your wool? Wool is also an excellent raw material! ”
