Abstract: | The splitting tendency of viscose and modal fibers in aqueous alkali solutions of LiOH, NaOH, KOH and TMAH was investigated.
The viscose fibers splitted up to 5–7 fibrils, whereas modal fibers splitted up to 2–4 fibrils depending on alkali type and
concentration. The fibrillar structure of lyocell enables it to split more (15–20 fibrils) than viscose and modal fibers.
Splitting occurs where internal stress of fiber is high due to different alkali or void distribution inside fiber. The splitting
test couldn’t be achieved for viscose and modal fibers between 1 and 5 M concentration of NaOH and TMAH solutions due to breakage
of fibers during test. Above 5 M concentration, no split can be observed due to even distribution of alkali inside fiber.
