Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for manufacturing a regenerated cellulose fiber using a natural dye. Specifically, a natural dye sol-gel prepared by a sol-gel process is prepared into a dispersion liquid, and then mixed with a viscose spinning liquid for wet spinning to obtain a regenerated cellulose fiber.
