| titleOfInvention | Manufacturing method of carboxylated cellulose fabric and manufacturing method of facial mask using the same |
| abstract | The present invention is a first padding step of immersing the cellulose fiber in a mixed aqueous solution of sodium hydroxide and sodium chloroacetate and padding; A secondary padding step of immersing the first padded cellulose fiber in an aqueous solution in which carboxymethyl cellulose is dissolved and secondary padding; Aging step of aging the secondary padded cellulose fiber; And it provides a method for producing carboxylated cellulose fibers comprising a drying step of drying the aged cellulose fibers. According to the manufacturing method of the carboxylated cellulose fiber of the present invention, it is possible to manufacture a carboxylated cellulose fiber with improved transparency when impregnated with moisture only by one aging process. |
