DANSK DS/EN ISO 105-Z06 PDF

This standard describes a test method to compare the migration propensity of dyes and the effect on migration of different types of migration inhibitors, thickeners and electrolyte. The method may also be used to evaluate a pad liquor with which migration has been found on a continuous dye range. Fabric impregnated with dye alone, or with test dye and migration inhibitor, is dried while partially covered with a watch glass, permitting differential drying and therefore, migration to occur. The degree of migration is evaluated by visual examination or by reflectance measurements of the covered and uncovered areas.
