Abstract: The cross-linking between the cell wall structures of cotton fiber can be damaged by NaOH solution.The cotton fibers were treated by different concentrations of NaOH,which was from 0.5 mol/L to 4 mol/L.And the morphological changes were observed under the microscope camera.The results showed that 3 mol/L NaOH distorted the natural cotton fibers,and the natural distortion of cotton fiber disappeared when the concentration of NaOH reached 4 mol/L.When the cotton fibers were treated by 1,2 or 3 mol/L NaOH,the natural cotton fiber distortion only disappeared in 4 mol/L NaOH.When dealed directly with 4 mol/L NaOH,the natural cotton fiber distortion also did not exist.

Key words: Cotton fiber, External morphology, Natural distortion, NaOH
