Application of Defoaming Agent in Textile Printing and Dyeing
?
During the processing of textiles, various dyes and printing, and dyeing auxiliaries are exposed. These auxiliaries, including surfactants such as detergents, penetrants, emulsifiers, and?leveling agents, tend to generate foam after mechanical vibration. The foam is the dispersion of air in the liquid. These foams will reduce the contact surface between the fabric and the liquid during the printing and dyeing process of the textile, resulting in uneven processing, which seriously affects the quality of the textile.
After adding a defoaming agent to the printing and dyeing auxiliaries solution, the defoaming agent can become a solution, an emulsion, or a dispersion, which is adsorbed on the surface of the foam. The defoamer chemical?will attract the good foaming substances of the surfactant so that the surface viscosity of the foam liquid film will be reduced, thinned, and broken.
I will introduce the application of defoaming agent in textile printing and dyeing in next artile.
