Title:
PREPARATION METHOD FOR CELLULOSE SPINNING SOLUTION, PRODUCT PREPARED THEREFROM, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/066728
Kind Code:
A1
Abstract:
A preparation method for a regenerated cellulose fiber, the preparation method specifically comprising: dissolving a cellulose raw material by using a cellulose solvent system to obtain a dissolved solution; adding a stabilizer into the dissolved solution, uniformly mixing, and filtering to obtain a cellulose spinning solution, wherein the stabilizer is a metal sulfate; defoaming and spinning the cellulose spinning solution to obtain a regenerated cellulose fiber. In the preparation method, the addition of the stabilizer can prevent cellulose macromolecules in the cellulose spinning solution from being excessively degraded, thus effectively protecting cellulose macromolecules in the spinning solution, improving the strength and toughness of the regenerated cellulose fiber prepared from the cellulose spinning solution, and the prepared regenerated cellulose fiber filament has high strength, good toughness and high quality.
