THE EFFECT OF PREPARED SAMPLES OF SEQUESTRATE AGENTS AND CHELATING SURFACTANTS ON THE MODEL WASHING

Abstract

In this work presents the results of model washing with addition of prepared samples of sequestering agents and chelating surfactants. After 20× repeated washing in hard water of 22 °dH (given in German degrees of hardness) were determined the content of ash and Ca2+ ion. The image of fabric after the model washing was evaluated by means of images from a scanning electron microscope.
