    The use of polyether defoamer is more common, mainly under the catalytic action of potassium hydroxide, propylene glycol or glycerol and propylene oxide, ethylene oxide, etc. polymerization to produce a powerful defoamer. Features are no color spots, etc., suitable for most of the silicon-free defoamer industry as defoaming and foam inhibition are needed. However, in contrast to the characteristics, it also has certain shortcomings. So we have long put the top priority on some creative design level so that some new type of polyether molecular formula is enough to be developed out of the product so that it can make polyether defoamer has more excellent characteristics.

    The application of polyether defoamer in the textile industry:

    Polyether type defoamer added in bleaching and washing can improve the treatment effect, so the requirements of good penetration of defoamer, high temperature resistance, uniform dispersion, can make the desizing agent, practice bleaching agent, and cleaning agent, and so on consistent penetration into the fabric and can not form a silicon spot.

    Add in the dyeing slurry, eliminate foam, and avoid the formation of color spots, color spots, and color unevenness on the fabric due to foam, and other undesirable phenomena. The process requires an antifoam agent that is resistant to high temperatures and does not affect the beauty of the product. Excessive addition of silicone defoamer is likely to cause uneven dyeing, the phenomenon of silicon spots, and the formation of color spots. And the use of polyether type defoamer will not have this phenomenon.

    Textile printing with polyether defoamer in the textile printing process, to avoid foam leading to white spots, spots, or making the fabric pattern color uneven, blurred, and so on, so the added defoamer must ensure product quality, can not affect the viscosity of the paste, color appearance, etc., can quickly disperse, strong self-emulsification, low and high viscosity system can maintain a lasting anti-foaming effect.
    Notes on the use of polyether defoamer:

    Add polyether defoamer, you need to pay attention to the addition of the amount added. By adding the amount of measurement, so as to determine the specific amount of use, generally will be controlled at one ten-thousandth to one thousandth. In adding such a polyether defoamer, you must first add it according to the specific situation. You can directly add to the use of the media environment, in addition, you can first dilute a specific ratio of water and then directly add to use.
