Polymer system of cotton

The cotton polymer is a linear, cellulose polymer. The repeating unit in the cotton polymer is cellobiose which consists of two glucose units. The cotton polymer system consists of about 5000 cellobiose units, that is its degree of polymerisation is about 5000. It is a very long, linear polymer, about 5000 nm in length and about 0.8 nm thick. Cotton is a crystalline fiber. Its polymer system is about 65 to 70 per cent crystalline and, correspondingly, about 35-30 per cent amorphous. Therefore, the cotton polymers are, in the main, well oriented and probably no further apart than 0.5 nm, in the crystalline regions.
