AATCC Test Method 188-2010
to Sodium Hypochlorite Bleach in
in 2000 by AATCC Committee RA60.
Purpose and Scope
1.1 This test method is used to determine the colorfastness to sodium
hypochlorite bleach, commonly called "chlorine bleach," in home laundering
of textiles which are expected to withstand frequent laundering.
1.2 Results of this test method may be used in combination
with other testing for establishing care instructions.
If a chlorine bleach contains ingredients other than the sodium hypochlorite,
it is the total effect of these chemicals on the color change that is being evaluated.
1.4 This test method is designed
for home laundering devices. An accelerated colorfastness test simulating multiple
home laundering (including those with sodium hypochlorite) is described in Test
Method 61, Colorfastness to Laundering: Accelerated. There
is no known correlation between those sections of Method 61 and this method.
2.1 Specimens are laundered under appropriate conditions of temperature, detergent
solution, chlorine bleach solution and abrasive action for five home laundering
cycles. The laundered specimens are evaluated for color change.
