Lyocell纤维在NaOH溶液中膨胀规律的研究

A study on the swelling regular pattern of Lyocell staple fiber in NaOH solution

研究了 Lyocell纤维在 Na OH溶液中膨胀的规律 .发现在 1 1 %左右浓度的Na OH溶液中 ,Lyocell纤维的径向膨胀率最大 .揭示了 Lyocell纤维经 Na OH溶液反复膨胀处理后呈现的一些特点 ,并结合 Lyocell纤维的结构特点对这一现象给以初步的解释 .

The regular pattern of swelling of Lyocell staple fiber in NaOH aqueous solution is studied in this paper.It is put forward in this paper there is a maximum value of swelling ratio of Lyocell staple fiber along radial direction in NaOH solution when the consistency is 11% for the first time .Some other characteristics revealed when Lyocell staple fibers were soaked in NaOH solution were also presented in this paper.A preliminary explanation of the phenomenon is given on the basis of the structural characteristics of Lyocell staple fiber.
