Solvent dissolving cellulose is mainly achieved by breaking hydrogen bonds. According to the different dissolution conditions or the reaction medium and mechanism of cellulose dissolution, the solvent system for dissolving cellulose can be divided into two ways: one is solvent A derivatization solvent that chemically reacts with cellulose to form derivatives to break the hydrogen bond of cellulose to achieve the purpose of dissolution; the other is a direct solvent, that is, a non-derivatized solvent, which does not chemically change with cellulose and directly dissolves cellulose . Among them, according to the difference of the solvent phase, the direct solvent of cellulose, that is, the non-derivatized solvent system, can be divided into water-phase direct-soluble system and non-aqueous direct-soluble system. The following will specifically describe the research progress of various dissolution systems of cellulose fibers.

Solvent dissolved cellulose is mainly achieved by destroying the hydrogen bond, according to the different dissolving conditions or according to cellulose dissolved reaction medium and mechanism, the solvent system of dissolved cellulose can be divided into two ways: one is the solvent and cellulose chemical reaction to form derivatives to break the cellulose hydrogen bond to achieve the purpose of dissolution of the derivative solvent; Among them, according to the difference of solvent phase, cellulose direct solvent, i.e. non-derivative solvent system can be divided into water phase straight solubility system and non-water phase straight solution system. The research progress of various dissolving systems of cellulose fibers is described below.

Solvent dissolving cellulose is mainly achieved by breaking the hydrogen bond. According to the different dissolving conditions or the reaction medium and mechanism of cellulose dissolution, the solvent system for dissolving cellulose can be divided into two ways: one is the derivative solvent formed by the chemical reaction between the solvent and cellulose to form derivative, and the other is the derivative solvent that breaks the hydrogen bond of cellulose to achieve the purpose of dissolution They are direct solvents, i.e. non derivatized solvents, which do not chemically change cellulose but directly dissolve cellulose. According to the different solvent phases, cellulose direct solvents, namely non derivative solvents, can be divided into aqueous and nonaqueous systems.
