Cellulose exists in all plants, but the content is different. The cellulose content in plants is high, and cotton is the most valuable one. Therefore, cotton linter, which can't be directly spun, was first used to make viscose fiber. The cellulose content in trees is also high, so Europe has always used trees as raw materials for viscose fibers. Bamboo also contains cellulose, but the content is relatively low compared with cotton and trees. Therefore, for a long time, bamboo has not been used as the raw material of viscose fiber, mainly because of its economic value. Due to the development of modern economy, people pursue the freshness of products. The price of bamboo fiber made of bamboo is much higher than that of ordinary viscose fiber made of cotton pulp, which makes up for the defect of bamboo fiber's economic value. At the same time, with the development of modern media, bamboo fiber is packaged as a symbol of environmental protection, making it popular in the market.
In fact, bamboo fiber is a kind of viscose fiber, which belongs to a kind of chemical fiber. In its production process, the early pulp production is the same as the previous paper-making process, which has great pollution to the environment and water resources. Later sulfonation will also cause great pollution to the atmosphere. Therefore, the production of viscose fiber is strictly controlled in Europe.
The performance of bamboo fiber is basically the same as that of ordinary viscose fiber. At present, the bamboo fiber on the market has the so-called breathing function, which is only the performance obtained by a hollowing-out process in the gluing process, not the function of bamboo. Therefore, the so-called bamboo fiber that can release negative ions is even more nonsense!
