Vegetable tanned leather is a relatively popular leather material, mainly used on wallets. I believe many people have bought it, and the texture is still very good. The following editor on No. 5 will tell you what oil is used for vegetable tanning?

What kind of oil is used for vegetable tanned leather maintenance?

Generally, vegetable tanned leather is recommended to use mink oil for maintenance. A protective film is added to make the leather more moisturized, and the discoloration effect is not as obvious as that of cow horn oil, except for mink oil. I always recommend German leather care oil to my friends. The main ingredients are natural beeswax and jojoba oil. Its advantage is that it is not easy to cause leather discoloration, has a good smell, and the leather is also moisturized. Mink oil is like a natural protective barrier to prevent high temperature damage to the leather, but it is best to avoid the strong light period at noon; choosing mild sunlight can also make the surface oil better absorbed. There is another important reason for sunlight, because the plant tannins in vegetable tanned leather will be emitted out when encountering high temperature, which will directly cause the color of the leather to change. Mink oil also has a certain color change effect. You can choose to 'sunbathe' on sunny days for several consecutive days. .

Introduction of vegetable tanned leather material

What is vegetable tanned leather? It is different from chrome tanned leather. Chrome tanned leather is our common leather material for handbags, clothing, and shoes. It is made of chrome-containing tanning agents. The leather is soft, light, stretchable and colorful. Vegetable tanning is another leather processing technology that uses plant-derived tannins to tan leather. Compared with common chrome tanning, vegetable tanning is less malleable and elastic, but its texture is very strong ( Therefore, the ductility is poor) and the water absorption is very strong.

Because vegetable tanned leather is generally of primary color, the coating is almost invisible, so the pores are more clearly displayed on the surface. It is precisely because of this that it is easier to absorb water. Vegetable tanned leather has the effect of dripping and discoloration. The dark color may not be obvious, but the light color and white color are obvious. After the dripping water penetrates quickly, the leather surface will turn red. After a while, the color of the leather will change. Go deeper. With the increase of the use time, the leather surface will gradually become brownish yellow. After a while, the color will stabilize. After maintenance, the gloss of the leather surface is very good, and it becomes the color of old beeswax that many people like to say.

How to clean vegetable tanned leather

For the cleaning of leather, I recommend using saddle soap. Dip a soft cloth with water and draw a circle on the saddle soap, then continue to draw circles on the leather. Wipe, it is easy to wipe off the stains, and then use a dry soft cloth to absorb the moisture. I also used this method to erase the silver pen marks when I made leather goods. I have also bought a rubber for vegetable tanned leather. I personally feel that it is not easy to control, and it is easy to cause the rubbing part to be white. After cleaning with water, apply maintenance oil to replenish the oil in the leather.

Going back to this question, the leather was stained with water. In principle, the traces will disappear after drying. But it is also possible that the water penetrates too deeply, and the material in the leather comes out and causes discoloration. I also encountered After being in this situation, it was all wetted decisively, but it was just a leather strip at the time. You are not recommended to do this as a finished product. It is risky. If you are pursuing perfection, you can try to wet the strip with a wet sponge. Look at the picture. The leather is still very new. You can also rub some maintenance oil to speed up the discoloration.
