Abstract:
The disclosure relates to a method for decolorization of a dye-colored synthetic polymer, which includes the steps of treating a dye-colored synthetic polymer, such as polyester, with a treatment composition at pH 6 or less, the treatment composition comprising sodium formaldehyde sulfoxylate, water, and a ketone. The resulting decolorized synthetic polymer is then separated from the treatment composition.

Claim (Index 1):
A method for decolorizing a dye-colored synthetic polymer, comprising:\n treating a dye-colored synthetic polymer with a treatment composition, the treatment composition comprising\n (a) sodium formaldehyde sulfoxylate, \n (b) water, and \n (d) a ketone dissolved in the treatment composition; \n wherein the treatment composition has a pH of 6 or less, and the treating is carried out at a temperature of at least 50\u00b0 C. and for a duration of time sufficient to at least partially decolorize the synthetic polymer; and \n following the treating, separating at least partially decolorized synthetic polymer from the treatment composition.
