The invention discloses a polyester-cotton dispersion reactive one-bath dyeing process and dye liquor components. The dye liquor includes the following components: reactive dye, sodium sulfate, disodium hydrogen phosphate-citric acid buffer, disperse dye micelle, A nonionic high temperature leveling agent; the disperse dye micelle is prepared by mixing a pH-responsive block copolymer and disperse dyes in a certain proportion. The one-bath short-flow dyeing process provided by the invention has no requirements on the types of disperse dyes and reactive dyes, and the release of disperse dyes is regulated by adjusting the pH value during dyeing, which overcomes the easy hydrolysis of disperse dyes in alkaline dye liquor. question. |
