Luo Xingchen is not stupid. As soon as Su Tang said, she understood and nodded, "I understand. I followed what you said. This morning I ran to the largest cloth shop in the capital and bought all the fabrics. You Take a look."

Seeing Su Tang speaking like this, Luo Xingchen knew that he could feel relieved now, so he took out a thick wad of cloth like a handkerchief.

Yesterday Su Tang and Luo Xingchen talked about investigating the market. Is there always a start? After Su Tang reached level 30 this time, the supermarket opened. She unlocked an essential oil processing machine in the processing workshop, and then she searched in the supermarket. After a while, a lot of dyes were found.

Essential oils are good things. You can make a lot of things, including essential oil soaps, essential oil candles, and even sell essential oils directly. They can also be sold as skin care products. However, because essential oils require a lot of flowers and so on, threose does not buy a flower garden at the moment. It is inconvenient to directly make the product, you can put it first.

Dyes are much simpler, and they are not expensive to sell in space. If they can dye colors that are not available in this country, it will be a huge profit.

Because of this idea, Su Tang asked Luo Xingchen to get to know the cloth market in Beijing first. Luo Xingchen was indeed a career person. Su Tang only said yesterday. She got up and went to work early this morning. The materials are cut into similar pieces, which are convenient for Su Tang to see.

As soon as Su Tang saw that the materials in her hand were different, there were silk satin, cotton and linen, but the colors were rather monotonous.

The current dyes are all taken from nature, and the colors are mostly red. In addition to positive red, there are also silver red and light red.

Except for the red color, which is the yellow color, because some of this color is used exclusively by the royal family, the folks don't use it much. There is only a very light color of yellow, and materials that tend to be yellow are more common.

Then there is the cyan series. The different shades of cyan and blue are considered to be in this series, and the final is black, white and brown.

The dyeing technology at this time is still relatively traditional, unlike modern dyes that can be divided into countless different color numbers just by red, and the contrast of light and dark can also evolve countless differences.

"Just these colors?" Su Tang first glanced at the fabric Luo Xingchen gave her hastily, and said.

Luo Xingchen nodded, "I have also learned that the materials used for making clothes at the moment, depending on the raw materials, include cotton cloth and satin cloth, but there are only so many colors on the market, at most because of the difference in the different shades of materials. "

Hearing Luo Xingchen's words like this, Su Tang also brightened up, looking at her, "Which is the most expensive thing here?"

Luo Xingchen pointed to a thin gauze to give Su Tang, "That should be the material of this Tianshui green yarn. It is said that this color is very troublesome to dye, and the output is very low, so one foot is close to 100 taels, although it is not as good as Kesi. But it is also expensive, which is rare in the material."

Luo Xingchen is cautious, knowing that this is a market survey, so even if the Luo family does not do the fabric business, but Su Tang asked, she can clearly explain it.

Su Tang looks at this so-called Tianshui Bi material, it is actually a kind of tulle that is close to light blue and light green. It looks good, but Su Tang doesn’t feel so much when he looks at it. It is seen a lot in modern times. Up.

"Is this color difficult to dye?" Su Tang asked Luo Xingchen. From Su Tang's point of view, it was not difficult at all.
