Abstract
The present invention provides a combined dyeing method that includes: a scouring process (S12) of scouring a dyeing target material which is chemically dyed with a chemical dye to remove impurities remaining in the dyeing target material; an eco-friendly dyeing process (S13) of dyeing the dyeing target material with an natural dye; a mordanting process (S14) of adding a mordant to the dyeing target material to fix the natural dye to the dyeing target material; a cleaning process (S15) of removing the mordant remaining in the dyeing target material; and a drying process (S16) of drying the dyeing target material.
