Splitting tendency of cellulosic fibers. Part 2: Effects of fiber swelling in alkali solutions

摘要

The splitting tendency of lyocell fiber in aqueous alkali solutions like KOH, NaOH, LiOH and TMAH was investigated. Up to 5 M concentration of alkali solutions, cation type is important on splitting of lyocell. Above 5 M concentration, cation type is no more relevant to splitting of lyocell. At 1 M of alkali solutions, alkali retention value (ARV) and split number increase in the order of KOH
