Fällmitteln
Fällmitteln, also known as Fällmittel, are chemical substances used in the textile industry to set or fix dyes onto fabrics. They play a crucial role in the dyeing process by precipitating the dye molecules onto the fiber, thereby achieving the desired color. Fällmitteln are typically metal salts, such as aluminum sulfate, chromium sulfate, or iron sulfate, which react with the dye molecules to form insoluble complexes. This reaction is often facilitated by heat and specific pH conditions. The choice of Fällmittel depends on the type of fiber, the dye being used, and the desired color properties. Proper selection and application of Fällmitteln are essential for achieving consistent and vibrant colors in textiles.
