said unintentionally, the listener was intentional, after Yang Yuanzhao heard this sentence, his eyes suddenly lit up, before, he was hesitating, what is the use of these fine count fabrics, whether to sell them directly with grey fabrics, or to print and dye them into colors, what kind of color is good.

The words of the shopkeeper of the Qu family, as if opening a piece of the sky, like fine cotton, in the field of printing and dyeing, there has always been a distinction between monochrome and multi-color, a multi-dyeing technology, and even able to support a family, to obtain a hundred years, or even hundreds of years of income, in ancient times, has been secret, even in this era, foreign printing and dyeing factories, can do a good job of multi-color dyeing, there are few.

Color, not necessarily the more the better, the later generations pay attention to the harmonious matching, but in this era, even multiple colors can not be dyed along the lì, the multiplicity, in a certain case, has become the key to measure the price of cotton, at present, the most expensive cotton, is 120 yuan a horse, he is only two-color, to be exact, is two-color double-sided, one side of a color, such a dyeing method, is used as a secret technique, secret, but in front of chemical dyeing and scientific reality, there is no secret.

Countless inspirations erupted in Yang Yuanzhao's heart, and he quietly instructed Liu Shu a few words, and then hurried away, so that the eight masters who had always paid attention to him looked at each other, and no one knew what was going on.

Originally, there was an open and secret fight, after Yang Yuanzhao quietly left, the eight masters, none of them left, all lived in the Jin Chamber of Commerce, nothing is more important than muslin, got the largest share of muslin, for the sales of ordinary cloth they harvested, it is definitely a huge promotion, ordinary cotton cloth, the profit is at most one or two yuan, dismantling and selling, it will not exceed three yuan, but high-count cotton cloth, even the simplest, can get a profit of thirty yuan when dismantled and sold, the most important thing is that They are the best gift for an official. Lightweight, precious and practical, muslin almost has a bit of a high-end gift.

Leaving the venue, Yang Yuanzhao plunged into the real room, found 7 engineers who had studied the best dyeing, and began to try multiple dyeing. On the second day after he entered the real yàn room, the news that Yang Yuanzhao was doing multiple dyeing real yàn spread all over the eight Jin merchants, and all the family heads were a little unable to sit still.

High-count cotton cloth is the king of cotton cloth, multi-dyed cloth, but also the king of dyed cloth, the combination of these two kings, isn't it the supreme throne, no one has ever equated the two before, after all, the British mostly sell some calico, or flower cloth, multiple dyeing does not seem to be involved, ordinary dyeing workshops, even if there is a secret recipe, who is willing to use ten times the ordinary cotton high-count cotton cloth to make a real yàn.

In the real yàn room, there is Yang Yuanzhao's open thinking, coupled with the background of the previous dyeing research, so that he has taken a lot of detours, the secret of multiple dyeing was soon learned, and then the rendering of colors, Yang Yuanzhao didn't know how to think of the principle of the three primary colors, after experimenting with dyes and finding dyes that can be mixed and dyed, multiple dyeing suddenly changed from imagination to actual operation.

The real yàn building, the largest room on the second floor, seven or eight engineers, more assistants, are all surrounded in front of a steam dyeing machine, this is Yang Yuanzhao led by multiple dyeing, three-color printing and dyeing method, the three colors will be combined together to form a colorful pattern, a certain Cheng dù above, this is a pioneering achievement, this era, double-sided printing and dyeing have been amazing times, not to mention the colorful pattern of the three primary color overprints, once made, it will cause a great sensation.

Colorful dyeing, can not use the dyeing pool, the pool to solve the double-sided, is already difficult, the three colors are simply going to die, similar to the real yàn, four or five times before, in the summary of a series of experience, the use of steam dyeing, different formats of cloth, through guò different methods, through the steam printing and dyeing machine, in which the control zhì must be extremely accurate, this can complete the process.

It has been tested several times in the real yàn room, and this printing and dyeing machine has also been passed through three or four rounds of different printing and dyeing processes of Yang Yuanzhao, and basically completed the adjustment of the machine qì, which is the seventh real yàn, and it is also the one with the highest success rate.

7 engineers, several times the assistant, and the sister printing and dyeing master, staring at the strange machine in front of them, 80 pieces of fine cloth, even if it is just white cloth, in the eyes of the master who is familiar with printing and dyeing, it can't be so bad, double-layer overprinting, is it so easy, that is the craftsmanship of the palace, even if there is a miracle of dyeing cloth before, their hearts are still bottomless, seven up and down.

On the contrary, Yang Yuanzhao calmed down a lot, the place of study has been thoroughly studied, and the adjustment of the machine has also been completed in the fine-tuning again and again, waiting only to see if it can reach the expected height.

Under the fixation and control of the machine, the first layer of successful past, just like on the white canvas, echoing a regular figure, the steam has been specially adjusted, and it can be in accordance with a regular shape**, this is the most intuitive solution he can think of, just like the spray paint of later generations, when the temperature of the steam decreases, an engineer stepped forward, carefully observed the white cloth, used a ruler, calculated the graphics printed and dyed on it, and then made a comparison with the notebook, As expected, there is hardly much difference. The Engineer nodded, signaling that the step was successful.

Crowd around, a burst of suppressed sound of pumping, this step, is the most difficult step, the previous several failures, are ** not controlled zhì good, either more spray, or less spray, the color of the printing and dyeing is not very uniform, now this problem has passed, next, is the problem of accurate control, that is a small problem.

Several engineers stepped forward and made a series of adjustments to the steam dyeing machine, on the machine, control it, and then under the impetus of the power, this white cloth changed its direction and passed through the machine again, this time, between the colors, there are overlapping places, and after overlapping, relying on the mutual fusion of the three primary colors, a new color was formed.

This time, all the engineers came forward to check, almost all the Cheng Shi saw that the color is not uniform, that is, it did not achieve the predetermined effect, the color itself is mixed with the cotton cloth, and then added, some are not uniform, which will cause some places to be a little deeper, some places are a little shallower, in the previous real yàn, there has always been a problem, fortunately, after dozens of rounds of real yàn, with the efforts of many researchers, this problem has been almost solved, take this piece of white cloth as an exampleThe problem is not obvious, only at the edges, there is a slight color difference, which will make people feel uncomfortable.

This color difference, in the eyes of professionals, is very clear, is an obvious flaw, in the eyes of those masters, but full of magic, this printing and dyeing machine, has not yet completed the entire printing and dyeing process, can be printed and dyed twice, but there are three colors, three colors, warp and weft are distinct, there are obvious boundaries, bright and beautiful, as for the color difference, in their opinion, there is no zài at all.

The third printing and dyeing, but also the most important printing and dyeing began, not only need to complete the printing of the third color, but also 4 more colors, this is the most important step, less any kind of color, colorful cloth, can not be called colorful, it can not achieve the goal, can not produce a sensational effect.

Several engineers stepped forward, controlled the machine as usual, operated it, and made the final adjustments, all the onlookers held their breath, waiting for the arrival of the final step, and the atmosphere did not dare to gasp, for fear that they would affect the birth of this perfect work of art.

At the critical moment, Yang Yuanzhao is very calm, he has always believed that the reality of science can reduce losses, increase fixed control and standardization, and is conducive to the improvement of product quality, which has been verified by later generations.

In the choice of the machine, Yang Yuanzhao has always chosen, with the machine to replace the role of people, with standardization, stylization, instead of a single individual subjective control of the above, the current steam dyeing machine is like this, the machine is under the control of a fixed program, will perfectly execute the next round of printing and dyeing process.

The sound of clicking, the machine slowly moved, and the white cloth once again entered the steam dyeing machine, the last color, like the last corner, is a fine product if it succeeds, and it is not successful, at most it is flawed, of course, this muslin, even if it is dyed in this color, it is also very good, compared to one or two colors of the British, I don't know how much to improve.

In fact, this process did not fail, under the precise scientific calculation, the cloth still completed the entire printing and dyeing process, the last color of the perfect printing down, very beautiful, the three primary colors occupy one-third of the space, followed by the other three colors combined with the two, the middle is the black mixed with the three colors, different colors, perfectly unified on a pattern, a total of seven.

It's not the color of the rainbow, but it's a perfect transition, I really want to say it in detail, those shades of color changes, it's also very perfect, a dyeing master, looking at this cotton, blurted out directly in surprise: "It's really ingenious!" ”

Yes, double-sided printing and dyeing is already ingenious, and it is known as a secret technique, not to mention the color, which is not dyed casually, but dyed by different combinations, which is even more exquisite.

If Yang Yuanzhao knew the idea of this master, he would definitely scoff at this, not to mention seven colors, 17 kinds, or even more, can be realized, the difference is to weave the cloth first and then print and dye, or first print and dye and then weave, the latter, can do more colors, but in order to achieve a good visual effect, you need to study it slowly.
