TRANSETIC TF-220F is a mixture of organic acids that are used as acid buffer to keep the pH value constant during the whole dyeing process of synthetic fibres like polyester, nylon and acrylic. It is suitable as an neutralizing agent after alkaline processes. Since TRANSETIC TF-220F is not volatile, it is recommended to be used in/after the last process step before drying the fabric on the stenter to guarantee a stable pH of 5.5 – 6.4 in the fabric during storing.
