Technical Parameter

Product performance

1. Polyester and its blended fabrics dyed with dispersed dyes were reduced and cleaned to remove float color.

2. Compared with the alkaline reduction cleaning method with sodium dithionite and caustic soda, there is no need to drain the liquid after dyeing, and the product is directly added. After the reduction and refreshing, the cleaning solution is slightly acidic, without neutralization. Shorten process time and save water.

3. It has a good chelating effect on metal ions, and the fabric is bright after cleaning.

4. It has a strong reduction effect in the acid bath, and basically does not produce the color yellow in the traditional reduction cleaning process, and will not affect the post-process because of the cleaning sodium dithionite and caustic soda.

5. Safety and environmental protection, relative to the reduction cleaning method of sodium dithionite + caustic soda can greatly reduce COD, and relieve the pressure of sewage treatment.
