What are the raw materials for papermaking?

There are two kinds of raw materials: plant fiber and non-plant fiber (inorganic fiber, chemical fiber and metal fiber). Can be divided into the following categories: plant fiber (wood, bamboo, grass, etc. ), mineral fiber (asbestos, glass fiber, etc. ) and other fibers (nylon, metal wire, etc. ), and polymer materials obtained by petroleum cracking. At present, the paper used for writing, printing and packaging is still mainly made of plant fibers.

The world's paper-making raw materials are mainly plant fibers, and coniferous or hardwood wood used in some economically developed countries accounts for more than 95% of the total consumption.

In fact, there are six kinds of raw materials for plant fiber papermaking: 1. Conifer wood, such as larch, Korean pine, masson pine, Yunnan pine and Mongolian Gu Song; 2. It is hardwood, such as poplar, birch and eucalyptus. 3. Herbs: such as reed, bamboo, awn stalk, wheat straw, rice straw, Chinese alpine rush, sorghum stalk, bagasse, etc. 4. It is bast fiber, such as flax, jute, kenaf, sandalwood bark, mulberry bark, cotton stalk bark, etc. 5. It is a kind of wool fiber, such as cotton, cotton linter and cotton rag; 6. It is a kind of waste paper fiber, which is divided into first-class waste paper (unprinted white paper edges and scraps from factories or relevant units), second-class waste paper (printed waste books and newspapers) and third-class waste paper (all waste paper, old cardboard and broken cartons except the above two). _
