Renminbi paper is made of 95% cotton, 3% wood and 2% other chemical materials. Among them, cotton is mainly high-quality short fiber cotton, and the main producing area is from Xinjiang.
In fact, there are still many materials for making RMB. Although those chemical materials only account for 2%, they are indispensable and important materials. These materials can greatly improve the waterproof, rigidity and anti-theft functions of RMB.
As for choosing cotton as the main material, it is because the characteristics of cotton are much stronger than ordinary paper, which can make the RMB less fragile and stronger.
First, ink.
Ink is the main component of printed banknotes. All our printing industries actually need ink, but RMB is a different kind of ink.
The fourth set of RMB uses a variety of anti-counterfeiting inks, such as colorless fluorescent ink, metameric ink and magnetic ink. ?
In fact, in life, we will also find a small amount of counterfeit money in the market. Although the technology of these counterfeit money looks similar to real money, the biggest difference between counterfeit money and real money lies in the different materials used. The use of a variety of anti-counterfeiting inks is a technology that counterfeit money does not have, so it is easy for us to identify the authenticity of RMB.
Second, synthetic fibers.
There is also an important link in RMB anti-counterfeiting, that is, inserting it on paper? Ribbon? . ?
This so-called? Ribbon? It is made of synthetic fiber, and ordinary counterfeit money can't copy this material. Moreover, the embedding technology of RMB is very special, and counterfeit money is difficult to imitate.
Many people think that RMB is this? Ribbon? It's gold, but it's not. This kind of fiber is very special, not entirely metal.
Third, short cotton wool.
Why is it that ordinary paper is destroyed when it is washed in water, and most of it is rotten into a pile of paste, while RMB can remain intact even if it is washed in the washing machine several times?
The key lies in raw materials. The main component of RMB is short cotton wool, and the paper is smooth and tough, water-resistant and corrosion-resistant. Renminbi paper can be used for a long time without being damaged, and it also has certain chemical corrosion resistance.
The reason why our RMB can circulate for such a long time has a lot to do with its main component being short cotton wool.
The manufacturing process of RMB is very complicated. It takes a month to make a RMB, and you can imagine how complicated the manufacturing process is.
Therefore, there are many kinds of RMB materials, but short cotton wool accounts for the largest proportion.
