Problems solved by technology

[0002] The usual printing and dyeing process includes degreasing, rinsing, water washing, pickling, water washing, dyeing, water washing, pickling, water washing, soaping, water washing, color fixing, oversoftening and other printing and dyeing processes and finishing processes. The printing and dyeing industry is not only a large water user , is also a large sewage discharger. It is reported that more than 4 million tons of sewage are discharged into rivers, lakes and seas every day in the printing and dyeing industry. The composition of printing and dyeing wastewater is complex and changeable, with large chroma, high alkalinity, large changes in COD and extremely high BOD, and the treatment is difficult. It is so large that the recycling rate of printing and dyeing wastewater is less than 10%. At the same time, the discharged sewage will pollute 20 times the amount of water. Therefore, there is an urgent need for an efficient and green dyeing method.

Embodiment 1

[0018] Embodiment 1, a kind of efficient green environmental protection printing and dyeing method of the present invention, comprises the following steps:

[0019] (1) Rinsing: Put the fabric to be printed and dyed into a container filled with clear water at 35°C, add biological enzyme and clear water with a mass ratio of 1:20 into the container to immerse the fabric, and stir with a stirring rod. The biological enzyme is relatively mild Under certain conditions, high-efficiency reactions can occur, using biological enzymes to remove impurities on the fabric to be dyed, and complete the degradation of impurities at a faster speed;

[0020] (2) Cleaning: Take out the cloth after rinsing in step (1) and put it into the clear water pool, and add salt granules with a mass ratio of 1:25 into the clear water pool to form brine, heat the brine to 40°C, and Soak the rinsed cloth in a salt water pool for 4 hours;

[0021] (3) Drying: Take out the cloth after cleaning and soaking in s...

Embodiment 2

[0025] Embodiment 2, a kind of efficient green environmental protection printing and dyeing method of the present invention, comprises the following steps:

[0026] (1) Rinsing: Put the fabric to be printed and dyed into a container filled with clear water at 40°C, add biological enzymes and clear water with a mass ratio of 1:20 into the container to immerse the fabric, and stir with a stirring rod. The biological enzyme is relatively mild Under certain conditions, high-efficiency reactions can occur, using biological enzymes to remove impurities on the fabric to be dyed, and complete the degradation of impurities at a faster speed;

[0027] (2) Cleaning: Take out the cloth after rinsing in step (1) and put it into the clear water pool, and add salt granules with a mass ratio of 1:30 into the clear water pool to form brine, heat the brine to 45°C, and Soak the rinsed cloth in a salt water pool for 3 hours;

[0028] (3) Drying: Take out the cloth after cleaning and soaking in ...
