After the cotton seed (hair seed) after ginning, there are still short fibers, with the stripping machine to strip these short fibers, it is called cotton short lint. Cotton fleece consists of three parts; The first part comes from the longer fibers of the "hair head"; The second part comes from the fiber of the hair seed which is cut by the gin. The third part is a layer of short and dense fiber which grows naturally on the epidermis of cottonseed, which is the main component of cotton lint.
Grade I Cotton Linter
It is generally the first road velvet, the hand pull length of cotton fiber is 13 mm above (including 13 mm). A kind of wool according to its appearance form, the comparison material standard to determine the level. The Grade I cotton linter is mainly used for weaving cotton blanket, fleece and so on.
Grade II Cotton Linter
Generally for two, cotton fiber length of more than 12 mm (including 12 mm) fiber weight, the percentage of the total weight of the fiber is not more than 25%; The fiber weight of 3 mm or less shall not exceed 60% of the total fiber weight. According to its maturity, sulfuric acid insoluble matter, ash three indicators to determine the level. The Grade II cotton linter is mainly used as smokeless gunpowder, film, advanced paper, biological plastics and so on.
Grade III Cotton Linter
Generally three lines of velvet, cotton fiber length of more than 12 mm (including 12 mm) fiber weight, the percentage of the total weight of the fiber is not more than 5%; The fiber weight of 3 mm or less shall not exceed 80% of the total fiber weight. According to its maturity, sulfuric acid insoluble matter, ash three indicators to determine the level. The Grade III lint is mainly used to make high grade paper of chemical fibers.
Grade I Cotton Linter, because the length is long, and the maturity is not as good as, and, and the type of cotton short lint, therefore, generally used as textile raw materials, cotton, cotton, manufacturing high grade paper raw materials.
Grade II Cotton Linter, although the length is short, but the maturity is high, so it is the main raw material of the industrial extraction of cellulose, can also be used for the manufacture of smokeless gunpowder, celluloid and man-made fiber.
