Abstract
Alkali absorption method was used for reactivity measurement, in mechanical (ultrasonic) and oxidation (selective and non-selective and also by H2O2) treatments of alpha cellulose fibers made from cotton Linter. Evaluation of oxidation process and mechanical treatment of fibers by measuring of viscosity, cellulose molecular weight, carboxyl groups’ substitution in methylene blue methods and also fiber alkali absorption were shown that the mechanical treatment before chemical one was led to high accessibility and reactivity of fibers. Alkali absorption depends to fiber oxidation method and mechanical treatment before that. Results show that un-selective oxidized fiber with mechanical treatment compared to untreated samples increases reactivity and carboxyl groups’ substitution 2.49% and 51.45 mmol/kg, respectively.
