Abstract
An improved process for the purification of raw cotton linters includes the cutting of a first, second, third or mill run cut raw cotton linters to a particle size that passes through a 2,500 micrometer screen and then mechanically separating the linters into clean and unclean fractions. The clean fraction contains purified cut raw cotton linters and the unclean fraction contains the impurities.
