The reactions of most chemicals used to treat cotton cellulose are with the 2,3, and 6 hydroxyl groups, which are easily accessible and available. Hydrogen bonding in the crystalline microstructure restricts hydroxyl accessibility and avilability. Hydrogen bonding patterns on the accessible surfaces therefore control the degree and location of the chemical reactions. A method based on the reactio of cellulose with diethylaminoethyl chloride under very mild basic conditions evaluates changes i the availability of the hydroxyls. Any change in availability reflects changes in hydrogen bonding patterns, which has improtant implications for both wet and dry processing of cotton cellulose. Abstract.
