Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to compositions and methods for inhibiting dye transfer between fabrics during washing.

[0002]

BACKGROUND OF THE INVENTION One of the longest and unsolved complications that arise during modern laundry washing operations is that some dyes are susceptible to release of dyes into the wash liquor. The released dye then transfers to other fabrics that are being laundered together.

One way to counteract this problem would be to complex or adsorb the diffused dye washed off the dyed cloth before it adheres to other articles in the wash liquor.

The use of polymers in detergent compositions to control dye transfer has been practiced.
