Cotton linter was then chosen as a sample of cotton textiles to
study the effect of temperature and NaOH concentration on the
enzymatic digestibility of the material. The material was treated
at 0 C, 23 C and 100 C with 0–20% NaOH for 3 h. The treated
materials remained solid in the solution, but swelled, where more
than 95% of the initial materials were recovered after the washing.
