Method for continuously dyeing cotton fabric by using reduced dye to enhance oxidation and omit soaping

The invention specifically relates to a method for continuously dyeing a cotton fabric by using a reduced dye to enhance oxidation and omit soaping and belongs to the technical fields of printing anddyeing. The technical problem to be solved is to provide a method for dyeing a cotton fabric by using a reduced dye, by which the use amount of an oxidant is increased and soaping is replaced with hotwashing. The adopted technical scheme is that the method for continuously dyeing the cotton fabric by using the reduced dye to enhance oxidation and omit soaping comprises the specific dyeing steps:mercerizing the cotton fabric, then, padding a dried fabric into a suspensoid dye; drying the fabric; padding a reducing liquid; steaming the fabric, namely washing the fabric for three standards; carrying out leuco body oxidation and ventilation; carrying out hot washing for two standards; carrying out washing and neutralization; and drying the fabric. Due to the regulation of an oxidation parameter, the reduced dye is suf
