    High Conductivity Is The Main Factor Affecting The Reuse Of Printing And Dyeing Wastewater
    Jun 08, 2018

    In the problem whether the bleaching and dyeing wastewater can be reused for production。In addition to focusing on several key indicators such as chroma, hardness, turbidity and pH value of wastewater, the conductivity of water is also an important indicator that can not be ignored. Electrical conductivity is the embodiment of metal ions in water. The water quality with high conductivity has little effect on the dyeing of chemical fiber products. But it has great influence on the dyeing of pure cotton products, especially the dyeing of reactive dyes. It will speed up the rate of dyeing. Causing problems such as tintage uneven,  color stain and so on.
