Chapter 1169 Transaction
"Theoretically, this is the case." Yang Dequan said: "However, computer jacquard generally uses simple colors, mostly single or two-color, while ancient brocade often comes in five or six colors, ah, by the way. Modern jacquard silk fabrics are also called 'satin jacquard'. It seems that Shu Brocade has always been a tribute product as you said. It doesn't matter."
"To put it bluntly, jacquard is a kind of program, but in the past this program was recorded in the flower book." Zhou Zhi was very confident about this: "Now that we have computer technology, As long as there are ready-made fabrics, through the relationship between their color, warp and weft arrangement, we can definitely use the computer to The algorithm was copied, then deduced from the original version, and finally restored using the Dahualou machine. "
"We are now able to use the Dahualou machine," Yang Dequan said with excitement. " There is no problem in weaving simple horizontal and vertical stripes, which is what was called 'Tiaojin' in ancient times."
“The technique of weaving Sichuan brocade on the Dahualou loom actually involves the process of pattern design, cross-stitching and weaving, and the cooperation between weavers and weavers.” Yang Dequan said: “The so-called embroidery refers to the longitude and latitude lines marked according to the flower book. Color, arrange the silk threads on the flower floor machine, and the rest of the weaving is the simplest.”
"Therefore, to restore the real Shu brocade, the most important thing is to create a flower original based on the existing Shu brocade cultural relics and give it to the flower puller. Elbow, do you mean that this guy can do it with a computer?"
“In fact, I want the computer to cut the line data in multiple rows and columns into horizontal and vertical cutting methods. into a pile of pixels, and then select one pixel at the same position and lift it to the surface. Finally, all the pixels on the surface form a desired pattern. This is the essence of jacquard." Zhou Zhi asked Yang Dequan: "Master Yang, Is my understanding correct?"
"Absolutely," Yang Dequan said. Said: "And there are actually not many dots in one position. When the warp was used as the starting point in the Tang Dynasty, there were at most three longitudes and one weft. That is to say, there were at most three colors of silk threads passing through the same position, which is what you said. A little bit optional."
"In the Song and Ming Dynasties, it developed into a weft-like flower, which doubled and became a position. Up to six threads of different colors can pass through at the same time, which means you have six options to choose from. "
Zhou Zhi was so confident about this, he smiled and said: "This trip was not in vain, at least it was a success. As for the graduate student’s thesis topic, I will report it to the department when I get back, and we will set up the topic.”
Then another question arose: "Oh, no, look at this lion brocade. It has many colors. There are far more than six kinds!"
"Look carefully again!" Yang Dequan said with a smile: "We What I just said is the upper limit of the colors that can be accommodated at a longitude and latitude intersection, but it does not say that all positions in the entire picture must be the same six colors! "< br>
“Hey, you’re stupid!” Zhou Zhi slapped his forehead: “Now I understand what you emphasized, why the flower book of ancient brocade is so important! This kind of weaving method can be almost ever-changing, it is too complicated, just rely on It’s almost impossible for the human brain to remember!”
“Can we recover?” Yang Dequan became worried again.
Zhou Zhi smiled and said: "Don't worry, computers are best at doing this kind of thing. However, you may need to take your collection of ancient brocades to Shu University to scan the high-definition images of both sides. Only with the drawings can we organize the research.”
"And when the time comes, I will definitely need you to teach the recovery team so that everyone can understand the principles of Sichuan brocade weaving so that they can write algorithms."
"That's no problem, we'll be here on call!" Yang Dequan Said: "If the lion in the green pond can be restored, it will be a happy man and a hundred flowers." , we are not inferior to our ancestors!”
After viewing the display, Yang Dequan took everyone to see the apprentices working. There are two areas here. Now everyone is displaying in the embroidery area and the brocade area. With two huge wooden looms, this is the famous Dahualou loom.
It took Yang Dequan and his apprentices a lot of effort to forge the two Dahualou looms from the remnants of cultural relics and records in classics, and to figure out the working principles.
The reason why it is called Dahualou is that it has one more heddle jacquard device than the ordinary loom. This device is located three feet above the loom and becomes the "Flower Building". Sitting on it, pulling flowers and lifting the heddle, he decides the pattern of the brocade.
At the same time, there is another person under the loom, sitting at the head of the machine, shuttling and beating up. The two of them work together to weave beautiful brocade.
The loom is six meters long and four meters high. The entire loom is composed of almost two thousand parts.
The most important data is the width, because the width of the loom determines the width of the final product. The width of the Dahualou loom is 1.4 meters, which is almost the maximum width for ancient people to stretch their arms to shuttle.
This is the highest achievement of ancient Chinese weaving technology. On this basis, the Frenchman Jacquard developed a perforated pattern board, using perforated cardboard and steel needles to control the jacquard pattern, which is equivalent to The flower book is divided into pages in order, and one cardboard is used in one step, which greatly saves labor and training time. The flower-winding worker's work becomes no longer important. He only needs to know how to operate and replace the cardboard in order.
Later, the action of replacing cardboard was programmed, and the up and down of the needle could be controlled by a computer. This is the working principle of modern computerized automatic jacquard machines.
After listening to Master Yang’s explanation, Zhou Zhi became more confident in the work of restoring ancient flower books based on ancient brocade patterns.
After seeing ancient brocade, looms, and understanding the production process, when you return to the reception room and look at Adelais silk, you will find that it is full of ingenious "lazy" ideas.
The process of segmented dyeing is actually to dye the pattern onto the warp in advance. After arranging the warp, the silk pattern is actually fixed, and the remaining process is shuttle weaving.
Of course, the patterns weaved using this method cannot be as diverse and complex as Shu brocade, but it also has a great advantage, that is, it is light and thin.
This is because there is no "jacquard warp skipping" when weaving, and durability is also taken into account.
In the oasis next door to Northern Xinjiang, such a piece of silk may be more practical than the thick and dense Sichuan brocade.
High-end clothing customization is also the business of the workshop. Especially after the "Hometown" hit, there has been an endless stream of orders for custom-made clothing from the workshop. Now that my mother Tang Qi and the others are buying clothes, Master Yang no longer has time to personally To do it, you can only cut it yourself and then arrange for an apprentice to sew it.
Fortunately, everyone already had an idea of the general design. Chi Xueli is now considered half an expert, and Zhou Zhi’s freehand painting skills are barely usable. Under Chi Xueli’s guidance, Zhou Zhi worked in Yang It is still possible to convey everyone's intention by adding a few strokes to the sketch drawn by the master's disciples.
When the matter was settled and the wages were discussed, Yang Dequan smiled and said: "There is no need for wages, but I have a request."
"What request?"
Yang Dequan pulled Jiang Shuyi out: "I would like to trouble Shuyi to take a set of promotional photos for the few sets of clothes we have made. Her temperament is very charming, and she has a classic charm. , combined with the beauty of the West."
"Huh?" Jiang Shuyi used to help her grandmother draw embroidery books, and she was also very interested in the art of embroidery. Today she followed Zhou Zhi and was eye-opening. Learned a lot.
However, she did not expect that she would be involved in the final matter, and she couldn't help but be surprised.
“We can’t use Tingting’s current image indiscriminately, but it’s okay if Shu Yi helps us take a set?” Yang Dequan added with a smile: “If you agree, Shu Yi, I will give you a set of ancient costumes after the filming. I’ll give it to you!”
"Deal!" Before Jiang Shuyi could say anything, Zhou Zhi had already clapped his hands and agreed: "But I have to take the shot!"
