Just like the effect of people washing the sheets (cotton fabric used to make cotton quilts) in the past, the cotton cloth is clean and tidy without wrinkles after pulp washing. Using cotton stalks and cotton linters as raw materials, it is made by heating with a proper amount of alkaline water at high temperature, and contains pure cellulose. The fiber is slender and elastic, tough and resistant to bending, and has good absorbency. The paper produced is fine, soft, and highly opaque. Cotton linters are coarse cotton wool that is used for weaving and filtering through the first process of rolling the fine cotton wool part of cotton. For example, cotton stalks are rich in grass and wood fibers, and there are some short fibers remaining on cotton seeds (wool seeds). These short fibers are peeled off with a fleece machine, which is called "cotton linters." Cotton linters are composed of three parts; the first part comes from the longer fibers of the "hair"; the second part comes from the fibers on the wool seeds that are crushed by the gin; the third part is a layer of short and natural growth on the epidermis of the cotton seed. Dense fiber, which is the main component of cotton linters.
