AATCC TM146-2011(2022)e, Dispersibility of Disperse Dyes: Filter Test

Related to ISO 105-Z04

1. Purpose and Scope

1.1 This test determines the dispersibility as evaluated by filtering time and filter residue of disperse dyes under standard conditions in aqueous media. Additional information such as variables which affect accuracy and repeatability of the test are specified.

1.2 This test method is to be used for determining the degree of dispersion at the specified conditions in aqueous media only.

2. Principle

2.1 A quantity of disperse dye is diluted, heated and passed through filter papers of specified micron size. The time needed for the dye dispersion to pass through the filter is then recorded.

2.2 Three tests are outlined according to intended dye application.
