After the forage harvesting team set off again, Wang Tiancai found that on the right side of the pavilion canteen, a tall pile of thatch had been piled up, and it seemed that the thatch collection group had come back once, but he didn't find it.

He found two people to spread the thatch flat on the ground to dry, although the thatch at this time has been completely dry, but the dried sleep is more comfortable, a smell of hay mixed with a smell of sunshine, Wang Tian feels that there is a function to promote sleep.

Wang Tian looked at the two baskets of red berry dye collected by Slender Toutuo, found two large dustpans, dried one of them, and left it for later use.

Then find a large water tank, pour the remaining basket of berries into it, mash it with a wooden stick, add the right amount of water and stir well.

In this way, a small half jar of red dye was made, and all the hands that were cut out yesterday were soaked in it, and one less stone was used to press it.

It's still too troublesome to make red paper in this way, so let Zhou directly add the dried fruits of this dye when making paper, and make a direct and excellent red paper, saving trouble.

Then he found Ling'er and asked her for a set of linen clothes suitable for Xiaoli's size and put them in the dye vat, which was to make a big red bridal dress.

After it was determined that the wedding was going to be held, Wang Tian asked Xiaoli and Ling'er to make it together, and at the same time, one of Huzi's clothes was made.

But Wang Tian didn't plan to dye men's clothes, because he didn't find a suitable dye, and the vegetable dye now only had red, which was suitable for dyeing directly on linen.

The other colors are too light, and Wang Tian has no way to bleach the linen now, and the dyes of other colors are basically ineffective on the dark linen.

The use of these light-colored plant dyes was only possible when the cotton in the tribe was able to be measured and then woven into white cotton cloth.

As for the color fastness of the dyes of these plants, it is not known now, but fortunately, they are all plant dyes, even if they are decolorized, they have no effect on the body, and this is the reason why Wang Tian does not use mineral dyes.

In order to create an atmosphere for the wedding, Wang Tian decided to dye a set of bridal clothes to try the effect, Wang Tian estimated that the decolorization is certain, after all, this is a water-based dye, at least it will be dissolved in water when cleaning, but the plant dyeing is safe, even if the color fades, it will not cause harm

In this regard, he decided to try dyeing technology, and when he was in college, in order to improve his ability to draw manually, he once audited the design course of the textile college, and learned about ancient Chinese dyeing technology.

As for the dyeing techniques of later generations, they are not discussed here because they are completely not operable.

The materials used for coloring in ancient China can be divided into mineral pigments and vegetable dyes, just like the materials available to Wang Tian now.

Among them, plant dyes are the main dyes in ancient China, and mineral dyes involve chemical knowledge, so it is not surprising that plant dyes were first applied to people's lives as a natural active dye.

The ancient ancestors mastered the properties of a variety of plant dyes very early, and invented a variety of dyeing techniques and anti-dyeing printing techniques known as "Valerian".

Dyes of various materials have their different coloring principles, although mineral pigments and vegetable dyes are pigments, their coloring principles are different.

Mineral pigments are colored by chemical adhesives to adhere to the surface of the fabric, but the color is easy to fall off when exposed to water.

Vegetable dyes are different, when dyeing, their pigment molecules change the color of the fibers by affinity with the fabric fibers, which is a process of osmosis.

The color used for printing and dyeing will be integrated with the fabric fiber, and the color will completely become the natural color of the fiber after the penetration is completed, although it is not easy to fall off or rarely fall off after being washed in the sun.

There are countless mineral plant dyes commonly used in ancient China, and the working people have created different dyeing processes according to the characteristics of different dyes.

For example, there are: direct dyeing, mordant dyeing, vat dyeing, anti-dyeing, color dyeing, etc., to what extent does the complexity of the process reach"", can clearly distinguish a hue, such as red, can be clearly divided into dozens of similar colors, this number has no difference with the modern 256-color color spectrum, and may even be more detailed.

The various plant dyes that the tribe has obtained now can be used for direct dyeing, only this red berry, and the other pigments are too elegant to be used directly.

And natural plant dyes, Wang Tian also knows two kinds, one of which is woad, woad is a kind of blue grass, blue grass refers to a variety of plants that can make indigo dye and be used to dye cloth, and is one of the earliest natural plant dyes used in China.

Many people have never heard of the name woad, but if there is another name - Banlan root, basically everyone is familiar with it, like thunder.

The root of woad is called Banlan root, which is the famous traditional Chinese medicine formula Banlan root that can treat SARS, when SARS was raging, it was once sold out of stock.

The part that can be used for dyeing is the leaves of woad, and the main production area of woad is the Yellow River valley in China, so there is no reason why it cannot be found around the tribe.

For woad, because of SARS, it is estimated that people all over the country know it, and there are few people who will not use Banlan root when various media introduced it overwhelmingly.

And Wang Tian knew in later TV dramas that the method of making blue pigment is very simple: pick the leaves of woad and stir it with lime to get blue indigo, and the ratio of leaf pieces to lime is 6:4. Because this mixture is shaped like silt, it is also called "soil indigo".

As a universal elixir, this Tianlong tribe must have, as a natural plant dye, Wang Tian will certainly not let go of its use.

Another plant that can be used as a natural dye is humulus, which is a kind of vine weed, which is widely distributed in the land of China, and therefore the names are different in various places, Lala Seedling, Lala Vine, Five-clawed Dragon, Grass, Big-leaved Five-clawed Dragon, Pulling Dog Egg, Cutting Vine, Black Grass, Ma Kudzu Vine, Kudzu Vine, Gele Vine, Poison Weed, Kudzu Grass, Astringent Radius Vine, Bitter Melon Vine, Saw Saw Vine, Snake Trunk Vine, Snake Cutting Vine, Raka Vine, Lara Vine, Astringent, Astringent, Baler Seedling, Astringent Seedling and so on

In the use of humulus, it has been used as a medicine in history, and there is no record of making dyes, and the use of humulus as a dye has benefited from the environmental trend of later generations.

At the same time, the grass has the advantage of antibacterial effect, because of this function, Wang Tian feels that it can be used as medical gauze.

This kind of weed tribe is everywhere, Wang Tian didn't pay attention to dyeing this piece before, so he has never taken care of it, the cloth dyed with humulus is yellow, and the difference in color will be very different from batch to batch.

Sometimes it is bright yellow like a yellow potion, and sometimes it is grayish-brown.

With these three natural plant dyes, the Tianlong tribe has enough of the three primary colors of red, yellow and blue, so the other colors will not be a problem.

However, the color of humulus is extremely unstable, and it is necessary to replace it with other ones in the future.

In terms of color matching, the brightness of the monochrome is the highest, and the brighter the color, and the brightness of the tricolor is the darkest.

Wang Tian took out the red paper that had been soaked for a period of time from the dye vat, and saw that there were still some pulp ingredients attached to the paper, which seemed to need to be filtered before being used in the future.

He hung the paper on a rope hanging in Hall 5 of the pavilion one by one, and found a pig brush to remove the flesh attached to the paper.

The reason why it is not dried directly in the sun is to reduce the deformation of the paper, and the paper that is dried in a cool place is not much different from new paper.

The soaked bridal dress was taken out by Wang Tian before noon, and the fuel was filtered by the dress, the residual dye in the clothes was wrung out and squeezed out, and then soaked and cleaned in the creek before being dried in the sun.

After the clothes are dried, they will continue to be put into the dye vat for a second printing and dyeing, this time Wang Tian added salt and alkaline water soaked in plant ash to the dye to strengthen its color fastness.

After the completion of the second printing and dyeing, the time unconsciously came to the afternoon, the clothes were cleaned again, and dried, and the third printing and dyeing and cleaning were carried out tomorrow, and the printing and dyeing of the entire garment was completed.
