DEFINATION
The resistance of the color of textiles of all kind and in all forms to Chlorine and non chlorine bleaches.
Since the powdered non-chlorine bleaches currently available contain ingredients other than the powdered
non-chlorine bleach; such as fluorescent whitening agents, bluing, etc., it is the total effect of these chemicals
on the color change that is being evaluated.

BLEACHED USED IN TEXTILES
• Regular bleach is not safe for some dyes and fabric types, including
spandex, wool, silk, mohair and leather. However, it is safe for cotton,
linen, rayon, polyester, nylon and acrylic fibers, unless a dye or finish on
the fabric is not compatible with bleach.
• Next came oxygen bleaches (hydrogen peroxide, sodium perborate,
sodium carbonate) that are safe for virtually all machine washable
fabrics. Peroxide bleach doesn’t contain chlorine, and is referred to on
garment care labels as “non-chlorine bleach”.
• Oxygen bleaches are also referred to as color-safe or all-fabric bleaches.
These products are also ideal for washing white items with spandex that
can’t be washed with regular bleach.

AATCC TS 001
PROCEDURE
Take 250 ml distill water
• Weight 4.7 gm CLOROX2 powder
bleach and it in the water and make
the solution.
• Pour this solution in the open dish.
• Place the specimen into the dish
filled with bleach solution.
• Dip the specimen in the solution
for 1 min.
• After 1 min take out the specimen
and rinse wash
• Dry the specimen in the air.
