摘要： NaOH溶液可以破坏棉花纤维细胞壁间的交联结构。本试验采用不同浓度的NaOH溶液处理棉花纤维,显微镜下拍照观察棉花纤维外部形态的变化。结果显示,NaOH浓度从0.5 mol/L开始依次处理棉花纤维时,在NaOH浓度为3 mol/L时棉花纤维的天然扭曲变形,NaOH浓度达到4 mol/L时棉花纤维的天然扭曲消失。当NaOH浓度分别从1,2或3 mol/L处理时,棉花纤维的天然扭曲也只有在NaOH达到4 mol/L时消失,直接用4 mol/L NaOH处理时棉花纤维的天然扭曲也不存在。

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
