Heya user!!

Cotton ➖cellulose (95%)
rayon ➖cellulose (starting material)

Cotton, like rayon and wood pulp fibers, is made of cellulose. Cellulose is a macromolecule made up of anhydroglucose unit connected by 1, 4 oxygen bridges with the polymer repeating unit being anhydro-beta-cellulose.

Cotton cellulose differs from wood and rayon cellulose by having higher degrees of polymerization and crystallinity. The degree of polymerization is the number of repeating units that are linked together to form a molecule of cellulose. Crystallinity indicates that the fiber’s cellulose molecules are closely packed and parallel to one another. Higher degrees of polymerization and crystallinity of polymers are associated with higher strengths.
