Lac + Dye is a chemical agent and the like. Its main components are mostly composed of pigments (Dye) and a substance with a specific function (Lac involved).
Pigments are the ingredients that can make the object show a specific color. There are many kinds of them, and according to the chemical structure, they can be azo, anthraquinone, triarylmethane, etc. The characteristics of pigments are related to the brightness and durability of colors, as well as their affinity for different substrates. In many processes such as fabric dyeing and printing, the quality of pigments directly determines the color phase and fastness of the finished product.
And Lac refers to a substance that has the functions of medium and fixation. In the dyeing process, it may enhance the combination of the pigment and the substrate, making the dyeing more uniform and firm. Or it can adjust the dissolution and dispersion state of the pigment, so that it can play a role more smoothly when applied.
If the ancient saying is, "Lac + Dye, the color material is compatible with the dyeing aid. The color material is essential for color rendering, its variety and different properties, and it is related to the beauty and firmness of the color. And Lac's division, or the role of matchmaking and color fixing, helps the color material and the object to be in harmony, so that the dyeing is smooth and beautiful, and the color is solid and not easy to fade. The two help each other, and they are very powerful in dyeing, weaving, and printing. "

Lac + Dye is a clever thing, and the scene of its application is quite involved. In the realm of "Tiangong Kaiwu", as the ancient saying goes, this medicine has a unique use.
In the field of weaving and dyeing, Lac + Dye is very useful. In the past, weavers often relied on this agent to obtain fabrics with bright colors and long-lasting non-fading. For example, when dyeing silk, the silk is immersed in a liquid containing Lac + Dye, and after the right time and heat, the silk will be gorgeous. It can make the color firmly adhere to the fabric, and it is not easy to peel off when the wind blows and the sun blows. In this way, the silk dyed can be made into luxurious clothes for the nobles to wear, showing elegance and luxury.
In the field of painting, Lac + Dye is also indispensable. Artists want to paint paintings with fresh and lasting colors, so they often use them to adjust colors. On rice paper or silk, use paint containing this agent to paint landscapes, figures, flowers and birds. Their colors are vivid and vivid, and the years pass without losing their charm. Whether it is court paintings or folk Danqing, they are all enhanced by Lac + Dye.
Furthermore, in the realm of utensils decoration, Lac + Dye can also play a wonderful role. Craftsmen want to beautify ceramics, wood and other utensils, often use them as color decorations. Apply Lac + Dye glaze on the surface of ceramics, and after kiln tempering, the colorful patterns jump on them, making the value of ceramics double. Painting on the wood can also make the wood elegant in color and add a touch of quaint charm.
From this perspective, Lac + Dye has an extraordinary performance in many scenes such as weaving and dyeing, painting, and utensil decoration, adding luster to the craftsmanship of the past and helping craftsmen achieve many exquisite works.

Lac + Dye is a craftsmanship made by workers. Compared with his similar products, there are three advantages.
One is the freshness of the color. The ancient dyeing, relying on plants and trees, although the color is natural, but the freshness is insufficient. It has been exposed to the sun for a long time, and the color is easy to darken. The color made by Lac + Dye, such as the dawn of the morning and the dawn, the beauty of the sunset, does not fade over the years, such as Qi is embroidered, and the viewer is pleasing to the eye. For example, in the past, silk was dyed with Su Mu as the color, and it was fashionable at the beginning, but not a few colors were light. Dyed with Lac + Dye, its color will stay for a long time, which can be the splendor of clothing or the splendor of the painting wall.
Second, it is very convenient to use. In the past, dyeing was a cumbersome process, requiring soaking, boiling, drying, and all kinds of operations, which was time-consuming and laborious. Lac + Dye is not the same. Its formulations are excellent, and it only needs to be prepared according to the recipe when used. When applied to the object, it will be colored in an instant without much effort. I still remember the dyeing of cloth in the past. It took ten months from the collection of materials to the completion. Today, Lac + Dye is used, but it takes a few days, saving a lot of manpower and time, and the workers are all right.
Third, the stability of sex is increased. Other dyes, when exposed to water or heat, change color easily, and even turn into nothing. Lac + Dye dyes things, water and fire do not invade their color, and wind and rain cannot erode their brilliance. In the past, there were dyed paintings, and the color flowed through the rain. If Lac + Dye was used for it, even when the rain poured down, the color could be preserved as before, and it could be a treasure handed down from generation to generation, and it could be new after a long time.
From this perspective, Lac + Dye is more similar to his production, with beautiful color, convenient use, and stable sex. It is actually a good product of dyeing and a good material for workers.

Lac + Dye is a wonderful method that is practical for dyeing and weaving. The method of its use is quite exquisite, and it needs to be carried out according to specific regulations.
If you want to use Lac + Dye, you should first prepare all the things used. Choose a clean utensil, hold an appropriate amount of water, and add Lac + Dye agent according to the amount of dye. Make sure that the agent dissolves evenly in the water. This is the key. If the dissolution is uneven, the color of the dye will not be uniform.
Then, gently place the thing to be dyed in the dye. At the beginning, you must turn it frequently so that the dye can touch the whole body, so that the coloring can be even. However, the flipping should also be moderate, not too violent, so as not to damage the dye.
The dyeing time is also fixed. The duration is dark, and the duration is light. It can be controlled in a timely manner according to the good chromaticity. During this period, when paying attention to the color change of the dye, you can also observe the color progress of the dye to determine whether it has reached the expected color.
And the temperature at the time of dyeing also has a great impact. It is appropriate to maintain a moderate temperature, not too high. If it is too high, the color will fail easily; if it is too low, it will be slow to color. Often use a warm fire to heat the dye slowly, so that the temperature is moderate and constant.
After dyeing, take out the dye from the dye, and gently rinse it with water to remove its floating color. When rinsing, be careful not to let the color of the dye fade due to vigorous scrubbing. After rinsing, dry it in a ventilated place, and do not expose it to the hot sun to avoid color change.
In this way, using Lac + Dye according to these methods can obtain a uniform color, make the dye shine differently, and increase its beauty and value.

For Lac + Dye, hide it in a dry, cool and dark place, away from direct sunlight, and away from heat sources. These two are delicate in nature. If the temperature is high, the quality is changeable, and the light exposure will gradually lose its effect.
Ancient treasures know the importance of dry, wet and light. If the treasure is placed in a box, choose a secluded and dry place, afraid that it will be invaded by moisture and damaged by light. The same is true for Lac + Dye. In dry places, it can prevent it from being damp and mildew, and prevent its quality from being damaged. Cool places avoid the disturbance of heat, and high heat can easily make them differentiate and lose their original effect.
Also, avoiding direct sunlight is the most important. Sunlight contains all kinds of rays, and long-term exposure to Lac + Dye can cause its color to fade and its structure to change. Like an ancient picture scroll, exposed to light, the color fades, and so does Lac + Dye. The heat source is close, and there is also a big problem. High temperature can promote its chemical reaction, making the performance unusual.
is to hide Lac + Dye, and it must follow the rules of cool and dark places, protected from light and heat, in order to ensure its quality and stability, so as to be safe for future use.
