The Business Line Industrial Specialties of Evonik Goldschmidt GmbH has its base in all kinds of organic specialty surfactants and organomodified siloxanes. hydrophobing and wetting agents. dispersing aids. technological background and application know-how addresses several industries like plastics. softeners and radiation curable release coatings. Our strengths are creativity. scouring agents. entering spreading rupture escaping gas 1 2 3 4 5 Figure 1.Product Range The textile industry is facing many conflicting challenges. the jet fills with foam and the production cannot proceed at optimum speed. Aside from the beneficial characteristics of surfactants (leveling agents. such as the need for higher efficiency. Care has to be taken that the applied antifoam does not negatively impact the fabric quality by staining the fabric. wetting agents etc. reducing cost through shorter product cycles while maintaining a high quality standard and continuously providing innovation. or added as an external antifoam. Our antifoam/defoamer product range comprises: • Concentrates • Emulsion concentrates • Ready to use emulsions Depending on the antifoam / defoamer. they are also responsible for the formation of foam during almost all stages of production. it can be either added as an internal antifoam – thus being incorporated into the textile auxiliary to prevent foam formation. Mechanism of defoaming = defoamer 3 . whereby being added at the occurrence of the foam to destroy it. or does not disturb the machine runnability.). For instance. excellent stability as concentrate. we offer silica and silicone oil free defoamers. Antifoam for jet dyeing. Antifoam for jet dyeing. In aqueous media. Predilutions have to be used immediately after preparation. the use of pre-dilutions (1:3 to 1:10 in water) is recommended. Pre-defoaming of surfactant concentrates. No silicone spotting. High stability as well as high efficiency during various textile application processes merge the advantanges of both organic and silicone antifoams. In addition. Emulsion concentrate with excellent jet stability and good electrolyte tolerance. for white water in nonwoven production using water entanglement. Predilutions have to be used immediately after preparation.
