摘要

Ionic liquid (IL)-made regenerated cellulose fibers show smooth surface

circular cross-section

highest tensile strength

moderate dyeing/fibrillation

good spinning/weaving

guiding their commercial use.

Abstract

As the global textile industry has accelerated its transition to a circular economy

iterative innovation in regenerated cellulose fibers has become a key industry focus. With viscose fiber having been industrialized for over a century and lyocell fiber gaining market recognition because of its environmentally friendly process

which is the next regenerated cellulose fiber. Herein

ionic liquids with low vapor pressure

nonflammability

relatively simple recovery

and high dissolution efficiency were used to fabricate regenerated cellulose fibers. The viscose and lyocell properties of the fibers were systematically compared

including microscopic morphology

dyeing behavior

fibrillation resistance

mechanical properties

yarn-forming capacity

and fabric performance. The ionic liquid (IL) fiber exhibited a smooth surface and circular cross-section

with the highest tensile strength

moderate dyeing and fibrillation properties

and similar spinning and weaving performance. This work can provide a reference for the commercial application of regenerated cellulose fibers fabricated from ionic liquid.
