AATCC Test Method 170-2011

Dusting Propensity of Powder Dyes:  Evaluation of

Developed in 1987 by AATCC Committee RA87

1.  Purpose and Scope

1.1  This test method provides a standard method for the evaluation of dusting properties of powder dyes.
1.2  The method of assessment permits the assignment of a numerical rating describing the degree of dusting; or, conversely, the degree of non-dusting of powder dyes
1.3  This test method is not intended for a quantitative determination of dusting.   Water soluble dyes may give an inferior rating than an equal amount of dusting caused by disperse dyes.  Further studies indicated that not all factors; i.e., humidity, are fully controlled.  Also the method does not distinguish between slow and fast settling dust.
