At dinner in the evening, Yun Xi saw that Song Jie was in a lot of spirits, so he discussed the start of the printing and dyeing workshop tomorrow, and the printing and dyeing workshop and the garment workshop were stopped in the few days that Yun Xi was away, because the printing and dyeing workshop would not print colorful patterns, and the garment workshop had nothing to do. Yunxi decided to start the printing and dyeing workshop first, while Song Jie was printing a piece of cloth first, and the garment workshop stopped first.

After discussing and going to sleep, Yun Xi slept unsteadily one night, dreamed that his garment factory was booming, and dreamed that his garment factory could not be run for a while, crying and laughing for a night, and finally fell asleep, and his brother knocked on the door again and shouted for dinner.

When Yunxi freshened up and sat down at the table slowly, he saw that everyone was looking at him, yawned and said, "Look at what you don't eat."

The mother asked with concern: "Niuniu, didn't you sleep well last night?" ”

Wondering, "Mother, how do you know?" ”

"I've all put on my glasses," Jia Chen said with a smile.

Song Jie said: "You go to sleep, I'll do it myself." ”

Yun Xi said with a smile: "That's so embarrassing, it's nothing, it's just a nightmare."

After eating, Jiachen and his brother went to private school, and his mother and father went to their own business. Yun Xi and Song Jie moved the printing and dyeing materials of a jar from his house to the workshop, Song Jie pointed to the five altars on the right and said: "These are all natural plant dyes, like cyan is made of dye from the juice extracted from blue grass, red is made of madder, yellow is Zhehuang......

There are many benefits of using plants as dyes: 1. Plant dyes are durable and do not fade.

2 Sources are widely like woody plants: bark, leaves, roots, branches. Herbaceous plants: humulus, horsegrass, airplane grass, etc. There are also teas, medicinal herbs, fruits, vegetables, etc.

3. Green and environmental protection: natural plant dyes are non-toxic and harmless, non-allergenic and carcinogenic to the skin. It has good biodegradability and environmental compatibility.

Then he pointed to the one on the right, and the jars were animal dyes, and there were lac carmine

There is also the most marginal fossil fuel, mineral dyes are a variety of inorganic metal salts and metal oxides, mainly brown-red, light green, yellow, white, after crushing and mixing can obtain more than 20 chromatographs; Such as cinnabar, etc. However, mineral dyes are rarely used now due to the fact that some of them contain heavy metals or too many harmful components, and the color fixation is not ideal.

Ancient Chinese dyeing techniques are divided into two types: thread dyeing (dyeing thread) and pi dyeing (dyeing cloth), but they both use two methods: flat dyeing (dyeing into one color) and flower dyeing.

Flower dyeing is the use of a certain method to make some parts of the silk thread, yarn or cloth dye and leave the pattern. The easiest way to dye flowers is to tie-dye or stun valerian.

The method of making zuò is to set the flower position on the silk first, pick up the flower position with a needle and fold it in a cross shape, and tie it twice with a thread, and after the flower position is all tied, it is dyed, dried, and dismantled by the knot.

Another widely used flower dyeing method in ancient China was batik, in which flowers were painted on cloth with a mixture of beeswax, insect wax, pine wax or gum and fat, and then dye and color in a dye solution at room temperature. After dyeing, the wax and grease are boiled and eluted to show the pattern. Batik will appear with ice patterns, adding beauty to the pattern.

After he finished speaking, Yun Xi looked at him in disbelief.

He smiled and said, "Don't be surprised, none of us are from this era, we are all from another world."

Yun Xi said, 'I want to ask you how do you know that I am from another world?' ”

Song Jie said: "With your lame reason, what kind of dream is guided by a master', the child's reason is only believed by ancient people, and then said that the child I am from China in the 22nd century, I am a biologist who studies paleontology, during a field expedition. encountered a landslide, rolled down the mountain stream and died, and later crossed to the body of a printing and dyeing master, and was unwilling to be ordinary, so he traveled to many places to learn the printing and dyeing techniques of various places, and said to Yunxi The little girl will talk about you! ”。

Yun Xi said; I'm also from China in twenty-two, and I'm excited that we're all Chinese, and in the twenty-second century I have two

I am a graduate of Harvard University. Once again, a plane crash in cross-border trade. Traveled into the body of an eight-year-old girl. is also unwilling, and wants to make a name for himself in another world, so he made up such a reason. ”

Song Jie said with emotion: "I said why the little girl opened a garment shop at the age of eight, it turned out to be a strong woman!" ”

Yun Xi said; "To each other, Mr. Song is actually a biologist. I admire it so much. I was dissatisfied with Mr. Song, when I was in school, I liked to study paleontology like dinosaurs and trilobites......"

The two men complimented each other for a while, and then began to look at the dye.
