Textilien. Farbechtheitspruefungen. Dispergierverhalten von Dispersionsfarbstoffen Textiles-Tests for Colour Fastness-Part Z04:Disperse Dyes Textiles. Essais de solidite des teintures. Dispersibilite des colorants de dispersion ISO 105-Z04:1995;
适用范围:This part of ISO 105 describes a method for deter-mining the dispersibility, as evaluated by filtering time and filter residue, of disperse dyes. This test method is used for determining the degree of dispersion under specified conditions in aqueous media only. NOTES 1 The results of this test method can vary widely unless all tests are run under exactly the conditions outlined. Any variation in the conditions can cause a test to be invalid. Results have been shown to be reproducible in several laboratories when the specified conditions are met. 2 Variations in results can be caused by differences in the diameter of the filter funnel, due to the differences in sur-face area which result, and to variations in the size and density of the holes in the filter funnel.
