CONSTITUTION:This method for dyeing comprises dyeing cellulosic fibers with a reactive dye having a structure in which copper can be coordinated and then treating the dyed fibers with copper. Furthermore, the characteristic of this method for post-treating a dyed material comprises treating the dyed cellulosic fibers with a treating liquid containing a copper salt and a fixing agent together in the treatment thereof with the copper. |
