The present invention provides a cellulose dyed product formed by spin dyeing with a heavy metal-containing dye by an amine oxide process, particularly a cellulose dyed product in the color range of yellow, orange, red, and brown. (I) cellulose is dissolved in a water-soluble tertiary amine oxide to form a cellulose solution, wherein the cellulose solution is partially substituted with titanium by one or more heavy metals; and There is further provided a dye comprising, as a main component, titanium oxide or spinel (MgAl2O4), in which magnesium is partially or completely replaced with one or more heavy metals, respectively, and lowering the rising temperature of the cellulose solution to a maximum of 10 ° C according to a temperature stability test. A cellulose dyed product which is added and (ii) formed by forming the cellulose solution with a molding tool and (iii) precipitating cellulose from the formed cellulose solution.
