1. Coarse cotton (cotton that has been eliminated)
Also called Asian cotton, it refers to cotton of various varieties of cotton and grass cotton. The fiber is thick and short, and it is full of elasticity. Because of the short length, thick and hard fibers, white or dull white color, less mercerization, low use value and unit output of this kind of cotton fiber, it has been basically eliminated in China, and there is no production of cotton in the world.

It is also called sea-island cotton. It refers to cotton and land-sea hybrid cotton of various varieties of sea-island cotton.

The main production bases of long-staple cotton in my country are in some areas such as Xinjiang. Long-staple cotton can be divided into extra-long-staple cotton and medium-long-staple cotton.
