THE EVALUATION OF NEW TYPES SEQUESTERING AGENTS AND THEIR INFLUENCE ON THE MODEL WASHING

Popis výsledku v původním jazyce

A sequestering agent or a chelating agent is a substance that removes a metal ion from a solution system by forming a complex ion that does not have the chemical reaction of the ion that is removed. These are used to eliminate water hardness and heavy metals, such as iron. The sequestration capacity was measured at 20oC and 90oC at different pH-values by precipitating opacity titration - so called Hampshire test. The prepared samples were tested at model washing conditions. After twenty times repeated washing in hard water 22odH, 30 min at 90oC was determined the contain of ash and calcium ion. The image of fabric after the model washing was evaluated by scanning electron microscope. This sequestrate agents may have a wide application for the textile industry.
