After the group returned to Yangguan, Huo Gang asked Lu Ji to come over, and then soon a spinning wheel was also taken out, seeing this spinning wheel, Huo Gang couldn't help but nodded, this is the most widely spread spinning machine in ancient China, a spinning machine that can be operated by one person.

"General, this is the spinning machine, may I ask the general what he commands." Lu Ji was also invited, and after the spinning wheel was arranged, he asked respectfully.

"That's right, you should be able to spin yarn, have you ever tried to spin wool?" Huo Gang asked with a smile.

"Of course, in fact, we didn't find out about the wool first, as early as the Xiongnu period, the people on the grassland began to weave wool, and it seems that the time was earlier on the side of the Great Eclipse." Anno next to him immediately spoke.

Hearing this answer, Huo Gang was no longer surprised, because after coming here, Huo Gang encountered too many things that he originally thought he didn't have, but in fact he had already had, and now that he heard that there was now a textile wool, Huo Gang didn't have any special expression.

"Have you ever tried to make wool into clothes?" Huo Gang asked again.

"Yes, wool is good for clothes, and it can be warm, but because it's too rough, we can only wear it ourselves." Anno nodded.

Huo Gang immediately understood why woolen products and clothes were not popular on a large scale. The reason is also very simple, or the ancient Chinese textile industry is too powerful, although the nomads on the grassland have made them into simple clothes or blankets, but there is nowhere to sell them!

There is no place to sell it, they can only use it themselves, so this thing has not become popular at all, it cannot form a trend, and there is too much wool on the grassland, if it is not sold, these things will naturally not be popular.

There is also the problem of cost, if the cost of wool cloth is not reduced to lower than ordinary silk silk, it will not be marketable at all, only so that ordinary people can easily afford it, it can completely open up the market.

This is how the famous sheep eating man in later generations was formed, but in this era...... China can be said to be the core of the world, the Western aristocracy, especially the people in these places, are pursuing the silk of the East, how rare are your wool products, your cost is high, and not as beautiful as others, naturally there is no place to sell.

If there is no place to sell it, there will naturally be no one to improve its technology.

To put it bluntly, it is still a problem of textile machinery.

"Then let's talk about the problem of the spinning machine, everyone Lu, you have seen such a spinning wheel many times, have you ever thought about adding spindles on such a spinning wheel, such as this rope wheel to drive many spindles at the same time, so that you can spin several threads at the same time, then the efficiency is naturally increased several times." Huo Gang doesn't understand the Jenny machine, but he understands the general principle, isn't it just to increase the spindle!

And it seems that Jenny is the inventor of the machine, and Jenny's husband can see that the spinning wheel is upside down, and the spindles can still continue to work when they are upright, so he thinks of adding several spindles at the same time.

"Well, what the general said makes sense, but I have heard that in the south of the Central Plains, there seems to be a kind of pedal spinning machine, which has three spindles for spinning, and can spin three yarns at the same time." Lu Ji thought seriously for a moment, then nodded and spoke.

Huo Gang: "......"

Although Huo Gang was prepared, this time Huo Gang was still a little confused, this thing is also there? This...... Should this be said that the Chinese are too good, or that the British are too special, and the eighteenth century is inferior to the textile technology of China during the Tang Dynasty?

However, this three-spindle pedal loom, Lu Ji said this, Huo Gang seems to have really remembered, China has it, but it is definitely not in the Tang Dynasty, if Huo Gang is not mistaken, it seems to be Yuan or Song?

That's not right, is there something wrong with the historical record of that thing?

"Have you seen everyone Lu?" Huo Gang originally wanted to ask if you had heard of it? Later, he stopped alive, because it would be too stupid to ask, if people hadn't heard of it, how could they say it.

"No, but this shouldn't be difficult, and if there are three spindles at the same time, it's nothing more than the transmission of the rope pulley, and you can add one more wire here." Lu Ji nodded.

Huo Gang: "......" He thinks that the way he, a traverser, opens up differently from other traversers?

"Then have you ever thought of erecting this spindle, so that it can be simply made into a rectangular shape, where there is a row of spindles side by side, and the transmission wheels are placed next to it, so that the spindles can be increased to eight, ten, or even two or three rows of spindles, at the same time, so that the spindles can even be increased to dozens, or even more than a hundred, of course, in that case, manpower will definitely not work, but animal power can be used!"

Huo Gang was a little unwilling, I didn't believe it anymore, he simply directly described the finished structure of Jenny's spinning machine.

Huo Gang really doesn't know the principle of spinning, but he has seen the video of the operation of the Jenny loom on station B in his last life, so he probably knows the general shape of the finished Jenny machine. It is a rectangular frame, with the transmission wheel next to it, and a row of spindles in front of it, which can spin a dozen or even dozens of yarns at the same time.

This time, Huo Gang's words finally made everyone else stunned.

"Stand side by side?" Lu Ji's cloudy eyes began to shine, he walked to the side of the spinning wheel, and directly began to gesticulate, Lu Mu immediately walked over and began to help, seeing them like this, Huo Gang finally breathed a sigh of relief.

If this doesn't shock you, I really can't help it, you can't just let me build a nuclear bomb.

It's not just Lu Ji himself, he even started a discussion with Lu Mu next to him, Yang Lao Wu once told Huo Gang that these craftsmen are all at the level of everyone, to be honest, Huo Gang felt it for the first time, and in ancient times, these craftsmen and craftsmen were also different.

Lu Ji is already very old, but as Huo Gang described it a few times just now, Lu Ji has already given some plans.

“…… If it's shaped like a long table, there are more than a dozen spindles side by side...... These spindles can be rotated by multiple belts, one wheel can drive one belt, you can drive two, ten belts. ”

“…… But master, if that's the case, one person's hands can't operate so much. Lu Mu said.

"Use the big and small gears, turn the rope wheel next to it, and the spindle will rotate dozens of times, so that more than a dozen spindles can pull more than a dozen yarns at the same time, tighten them once, and sort out the yarn once, so the efficiency can not reach more than ten times that of a single spindle, but seven or eight times is okay." Lu Ji said affirmatively.

"Moreover, I also have an idea, if it is a dozen spindles, it is difficult for simple people to operate, then the supply of raw materials can also be replaced by spindles, so that the following two groups of spindles, the upper group of spindles, and the lower two groups of spindles are extracted and then wound with each other, and finally form the finished silk of the upper spindles, what do you think?" Lu Ji asked.

Huo Gang: "......"
