Something he had never heard of before.
However, according to this person, this thing called the Jacquard Machine could be said to be a divine weapon in the textile industry!
Li Ke naturally wouldn't let go of this important information. He immediately opened Baidu Encyclopedia and began to search.
Soon, the information about the Jacquard loom appeared in front of him.
It turned out that the Jacquard was a type of loom, or rather, a very important device in a loom!
The weaving yarn was divided into warp and filling. The vertical was the warp, and the horizontal was the filling.
Actually, it was the same as Earth's geographical latitude and longitude.
The principle of weaving was to divide the warp threads into two rows. Each row had a number of warp threads according to the size of the fabric to be woven, while there was only one filling thread.
When a row of warp threads was lifted, the filling thread would pass through the two rows of warp threads. After passing through, the row of warp threads would be put down, and the other row of warp threads would be lifted. At this time, the filling thread would pass through again!
This was the process of weaving. As long as this step was repeated, the yarn that would break with a pull could be woven into a strong cloth.
If one only wanted to weave cloth of pure color, such as pure white or pure black, or other cloth with only one color, then ordinary shuttle looms could weave it.
He only needed to choose the color of the warp and the filling to be the same.
However, if one wanted to weave different colors on the same piece of cloth, or if one wanted to weave patterns, it was absolutely inseparable from the Jacquard machine!
For example, he wanted to weave a piece of black cloth, but he also wanted to weave a red pattern on the black cloth.
Then, when weaving, the black areas could be woven normally with black warp.
However, what should he do when he reached the red pattern area?
Then he would have to use a Jacquard!
A person sat on the top of the loom and held the red warp threads in his hand. When it was time to weave the red pattern, he would lift the red warp threads with his hand so that the filling thread could pass through.
This way, the red pattern was woven.
This was also the earliest hand-made Jacquards, manually operated.
However, this manual operation was too troublesome. He had to find the red warp threads one by one, which was time-consuming and laborious.
He could not weave much cloth in a day.
Therefore, in ancient times, there were clothes of different colors and patterns. Only high officials and nobles could afford to wear them.
Ordinary people could only wear pure colored clothes because this kind of cloth was cheap and did not need to be hand-woven.
In order to change this backward and inefficient method of weaving, Jacquard invented the Jacquard Jacquard machine in 1804.
It was to use pre-punched cards to control the color and pattern of the fabric!
To put it simply, it was to prepare a card and then punch holes according to the pattern that he wanted to weave.
Then, he replaced the manual thread with steel needles that carried the warp.
Some of the steel needles were carrying black yarn, while some were carrying red yarn.
The pre-punched card was right above these steel needles. If there was a hole on the card right above the steel needles, then the card could be passed through and the yarn could be lifted.
If there were no holes on the card directly above the steel needle, then the steel needle would not move after it hit the card, and the warp thread on the steel needle would naturally not be lifted.
For example, at this moment, there was no need to weave patterns, so he only needed to pick up the black yarn.
What would the corresponding hole on the card look like?
That was, only the steel needle holding the black yarn had a hole right above it. The steel needle holding the red yarn had no hole right above it!
As a result, all that was lifted up was naturally black yarn.
Because the cards on the loom moved with the weaving process.
When it was time to weave the red pattern, the card holes on the steel needles became the exclusive holes for the red pattern.
In other places where there were no patterns, the steel needles of the black yarn could pass through the holes and lift the black yarn up.
Where there was a pattern, only the steel needle of the red yarn could pass through the hole and lift the red.
This way, the pattern could be successfully woven.
It looked quite complicated, but in fact, it was to replace the previous manual thread lifting with punching cards instead of manual work.
Artificial thread lifting was to use the eyes and hands to find the colored thread one by one.
The card punching process was set in advance, and each weaving process corresponded to a punched card.
In the process of weaving, I need to lift as many red threads as I need to and punch holes in the corresponding places of the steel needles of these red threads and black threads.
In this way, during the weaving process, the punched cards would replace the manual search and screening, and the required thread would be lifted accurately and quickly.
Moreover, this kind of card with holes could be used repeatedly. If he used a steel plate as a card, as long as he didn't feel that the pattern was outdated, he could use it forever!
Just like engraving printing, a card with holes was like a printed engraving. As long as the engraving wasn't broken, it could keep printing the contents of this page.
As long as the punched card was not damaged, it could be used to weave cloth with this pattern.
It was unlike artificial embroidery, where even if the pattern was the same every time, it still had to be lifted up one by one.
"Although it looks complicated, it's actually much simpler to understand the principle.”
Li Ke understood the principle of the Jacquard Jacquard after a while. The design was indeed ingenious.
According to his search results, the Jacquard machine was 25 times faster than the old handmade Jacquards!
It was equivalent to a leap from a bicycle to a car!
Furthermore, this was not counting the steam engine. Hand-made jacquards could not use the power of a steam engine.
However, the Jacquard Jacquard machine could use a steam engine. In this way, the speed of weaving was not only 25 times faster than the old-fashioned handmade Jacquard machine, but it was estimated to be more than 100 times faster!
"No wonder that person called the Jacquard Jacquard machine a divine artifact in the textile industry.”
Li Ke was very glad that he saw this person's reply. Otherwise, he might have missed out on such a magical weapon in the textile industry!
