Title:
RECYCLED CELLULOSE FIBER, METHOD FOR MANUFACTURING SAME, AND FIBER STRUCTURE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2022/124305
Kind Code:
A1
Abstract:
The present invention pertains to a recycled cellulose fiber that includes recycled natural cellulose microparticles, the median diameter of the recycled natural cellulose microparticles being 0.5-10 µm, inclusive. The recycled cellulose fiber including the recycled natural cellulose microparticles can be produced, for example, by extruding in a spinning bath, using a nozzle, a spinning solution obtained by adding an aqueous dispersion of the recycled natural cellulose microparticles having a median diameter of 0.5-10 µm, inclusive, to a spinning raw solution including cellulose, spinning and coagulating the solution, and generating the fiber. It is thereby possible to conserve resources and provide a recycled cellulose fiber including recycled natural cellulose that has good spinning properties, a method for manufacturing same, and a fiber structure including said fiber.
