The invention provides a fabric water-saving and emission-reducing dyeing and finishing process, comprising the following steps: plasma treatment, using a plasma treatment device to etch and modify the fabric to be dyed; desizing and bleaching, adding desizing enzyme, chelating Dispersant, dewaxing agent and scouring agent for desizing treatment, and then add hydrogen peroxide, sodium silicate, scouring agent and chelating agent for bleaching treatment; cellulase treatment, add cellulase to the bleached fabric for enzyme treatment; For pre-setting, use hot air to heat pre-setting with pin stenter; for dyeing, add water according to the bath ratio of 1: (1-2), add leveling agent, reactive dyes, sodium sulfate and acetic acid in sequence, and adjust the pH value to 4 ‑6, then increase the temperature at 1°C/min to 60°C, and keep it warm for 15-60 minutes. |
