What fruit did the ancients use to dye cloth in autumn?

In ancient times, people dyed cloth with various natural materials. Autumn is the harvest season, and many fruits and plants can be used to make dyes. Persimmon is a common fruit used for dyeing cloth. The relevant knowledge is as follows:

Persimmon has a long history in China. It was planted and eaten as early as the Tang Dynasty. Persimmon is bright red after ripening, and its color is bright and lasting, so the ancients used it to dye cloth.

2. The method of dyeing persimmon cloth is to mash persimmon, add water and lime, and then boil it to make the pigment in persimmon dissolve in water. Next, soak the cloth in this solution, and after a period of soaking and drying, the cloth will appear bright red like persimmon.

3. However, with the development of chemical synthetic dyes, natural dyes are gradually replaced. Modern people prefer to use chemical synthetic dyes, because their colors are richer and more diverse, and the dyeing effect is more stable. In addition, the production and use of chemically synthesized dyes are more convenient and economical.

The step of dyeing cloth usually includes the following steps:

1. Preparation of dyes: First of all, you need to prepare an appropriate amount of dyes, and choose different dyes according to the required colors and effects. Cloth preparation: wash and dry the cloth to be dyed to ensure no residue and impurities. Preparation of solution: put a proper amount of dye into water and stir evenly to make dye solution.

2. Soak the cloth: soak the cloth in the dye solution for a period of time to make the dye penetrate into the fiber. Boiling and dyeing: put the soaked cloth into a pot to cook, and the cooking time and temperature should be determined according to the nature and effect of the dye. Cleaning cloth: clean the cooked cloth to remove excess dyes and impurities.

3. Air-drying: Air-dry the cleaned cloth to avoid direct sunlight to avoid fading. In addition to the basic steps, you can also add some special treatment methods as needed, such as adding additives such as salt and vinegar to increase the depth and brightness of the color. At the same time, we need to pay attention to safety issues in the process of dyeing cloth, such as avoiding skin contact with dyes and inhaling harmful gases.
