Abstract
To find a more efficient and practically feasible cationization process for cellulose, periodate oxidation followed by a reaction with choline chloride was carried out in cotton. FTIR spectra revealed the presence of aldehyde carbonyl groups in periodate-oxidized cotton. The cationized cotton fabrics were dyed by acid dye to confirm the presence of cationic groups. Elemental analyses also indicated the presence of cationic groups. In general, oxidation temperature is an important factor in determining the oxidation effectiveness and, consequently, cationization. This oxidation cationization process proved to be practically feasible and environmentally desirable as an alternative cationization of cotton.
