Disperse/reactive dye modification one-bath dyeing technology for polyester-cotton/viscose fabric

The invention belongs to the technical field of textile printing and dyeing and in particular relates to a disperse/reactive dye modification one-bath dyeing technology for polyester-cotton/viscose fabric. The fabric is modified through color media or other modifiers, environment-friendly carriers are added into two disperse/reactive dye solutions, and a salt-free alkali-free or salt-free low-alkali normal temperature dyeing technology is implemented by using a one-bath two-step method. The technology has the advantages of simple process, convenience for operation and short dyeing time, a great amount of salt and alkali can be saved, energy sources are saved, and cost is reduced. By respectively adding a cross bond agent or a pH slippage agent or a small quantity of alkali agents into a dye bath, requirements for high fixation rate and high color fastness are met, and the technology is substantively changed and improved obviously by employing dye bath. Therefore, the technology has high social and economic be
