Abstract
This invention provides a process for preventing dye from depositing onto fabric, and fabric finishing compositions useful in the dye deposition inhibiting process of this invention. Specifically, a process is provided where 1) an aqueous bath is formed comprising a) water, b) dyed fabric, and c) a dye deposition inhibiting agent, 2) the dyed fabric is treated in the aqueous bath and the fabric releases a portion of the dye from the dyed fabric into the bath, and 3) the dye inhibiting agent is maintained in contact with the dyed fabric for the duration of the treating step. The dye deposition inhibiting agent is added to the process as a fabric finishing composition comprised of at least 0.1 wt % dye deposition inhibiting agent.
