Abstract

Based on the history of cellulose fiber development

the progress of three kinds of fibers

. viscous fiber

Lyocell fiber and ionic liquid fiber (Ioncell) with natural cellulose as raw materials are summarized. Firstly

the development history of regenerated cellulose fiber manufacturing technology is summarized

and the development status of viscose fiber

Lyocell fiber and ionic liquid fiber (Ioncell) with natural cellulose as raw material is summarized. In this work

the performance

application field

and market prospect are mainly introduced

and their technologies including spinning technology

the preparation of spinning solution

and the methods of solvent recovery are compared. In comparison with viscous fiber

both the dissolution of cellulose and the dry-jet wet spinning for the other two fibers show unique advantages. But their key points lie in the continuous preparation of spinning solution and efficient recovery of solvent. Compared to the NMMO solvent used by Lyocell fiber

ionic liquids (ILs) used by Ioncell fiber have the advantages of negligible volatility and properties tunable. Therefore

this kind of ILs with high solubility but without degradation ability of cellulose

high thermal stability to water and metal ions

and little environmental impact can be designed

which provide a new approach for the development of green spinning technology. In addition

the existing problems of Ioncell fiber are analyzed

and some research direction for the two kinds of fibers produce

d by solvent method are pointed out.
