Background

The cotton linters are cotton seeds (wool seeds) which are embossed with short fibers left thereon, and the short fibers are stripped off by a delinter. The cotton linters are composed of three parts, the first part is from the longer fibers of the "wool heads", the second part is from the fibers on the wool seeds that are broken by the cotton tying machine, and the third part is a layer of short and dense fibers naturally grown and developed on the cotton seed skin, which is the main component of the cotton linters. The cotton yield of China accounts for about 24% of the total cotton yield in the world, the world is the first, the corresponding cotton linter is large in amount, the cellulose content of the cotton linter is over 90%, and the cotton linter also contains a small amount of pectin (about 1%), wax (about 2%), lignin (2-3%), ash (1%) and the like, and is a high-quality fiber raw material for artificial fibers and the paper industry. The cotton linter fiber is shorter than the lint fiber, but has the same maturity, so the cellulose content is high, and the cotton linter fiber is an important raw material for light and chemical industries such as national defense, textile, chemical fiber, papermaking and the like, and is an important strategic material for the light industry, military industry, chemical industry and medical industry.
