These are related to the PH value news, in which you can learn about the latest trends in PH value and related information industry, to help you better understand and expand PH value market.
The Effect Of Water Quality On Textile Printing And Dyeing1.HARDNESSIt is generally accepted that a hardness of less than 500ppm has no effect on textile dyeing, and 200ppm is already very good quality water.The key is the content of metal ions, especially iron ions, which can lead to changes in col Read More
When dyeing nylon fiber, when the pH value of the dyeing solution is relatively high, the dye is rarely dyed; when the pH value of the dyeing solution drops to a certain value, the dye starts to be dyed, and soon reaches saturation. Continue to reduce the pH value of the dyeing night , The dye uptak Read More
Unreasonable formulation of the process or improper operation produces color fretting;The process is unreasonable (for example, the temperature rises and falls too fast)Poor operation, knotting during dyeing, and power outage during dyeing;The temperature rises too fast and the heat preservation tim Read More
The representative product of the substitute alkali for the phosphate system is Alkaflo developed by Sybron. The Morran patent provides a specific method for the substitute alkali for this system, and different raw materials can be used to prepare lye with different pH values. The main components of Read More
For reactive dyeing, when the pH value is 7-9, the color difference of the product is normal, indicating that the pH range has little effect on the color difference of the product, and the presence of a small amount of alkali will not change or destroy the chromogenic group of the reactive dye molec Read More
