Abstract

This invention discloses a method for preparing hydrophilic lyocell fiber, belonging to the field of functional cellulose fiber technology. The steps include: dissolving carboxymethyl cellulose, premixing cellulose pulp raw materials, preparing spinning solution, and preparing hydrophilic lyocell fiber. By introducing the hydrophilic cellulose derivative carboxymethyl cellulose, this invention not only enhances the hydrophilicity of the lyocell fiber itself but also strengthens its water retention capacity, expanding the application areas of lyocell fiber, without affecting the dissolution of cellulose itself. Furthermore, this invention can reduce the fibrillation degree of lyocell fiber to a certain extent, improving the fiber's antifibrillation effect.
