Abstract:

AATCC Test Method 101 is used to determine the colorfastness to bleaching. This method is

used to determine the fastness of colored textiles to the effects of bleach containing H 2O2. It isapplicable to dyed, printed or other colored fabric and to the testing of dyestuffs as applied to

textiles. This test method is intended for evaluating the resistance of the color of textile of all

kinds except polyamide, in all forms to the action of bleach baths containing hydrogen peroxide

at concentrations employed in textile processing. These tests are very important from quality

control aspect. As customers demand the specific fastness and one should meet the requirements

of customers.

3. Procedure:i. Bleach solution was taken in the test tube.

ii. A specimen of the textile in contact with white cloth was immersed in bleachsolution.

iii. Fabric was remained in solution for 2 Hrs. at 880C.iv. The composite specimen was removed from test tube and rinsed with cold water for

10mins.

v. The white specimen was dried and was compared with Gray scale for staining.4. Results:

The Gray Scale rating is from 4.

5. Discussion:The rating of 4 showed that no staining or a very little staining was produced.

6. Conclusion:The good rating of the sample showed that the dye used, was of good quality and compatible

with the fabric, resulted in very little bleeding.
