What is the specific use of textile printing and defoaming agent?

Answer:

Which jet cylinder overflow tank because the liquid in the tank in the high-speed cycle, so defoamers to withstand high shear.
Different printing and dyeing defoamers used in different printing and dyeing process
Defoamer can be used directly or added 1-10 times the water dilution, and then use, the dispersion effect is better. The specific method of operation is: first water added to the defoamer, and then quickly stir well, when used in the dilution of the system by the amount of 0.5-1 or so plus amount, you can defoamate.
Printing and dyeing is a wet treatment process, such as the production of a large number of foam, foam broken in the fabric, it is easy to cause printing and dyeing products. Defoamer is generally silicone products, the use of the process to ensure its stability, once the demulsification, easy to form silicon spots.
Long car, printing process, the general PH is high, so defoamer to high alkali. In addition to waterproofing and other finishing processing, to consider the defoamer and finishing agent compatibility, to ensure the safety can be used.
