Abstract (en)

[origin: EP2009087A2] A method for inhibiting or minimizing dye redeposition in decolorization of a dyed fabric containing cotton fibers involves contacting the fabric during the process with a redeposition inhibitor consisting of a polyester (I), obtained from (a) dicarboxylic acids, (b) 2-6C diols and (c) polyether alcohols containing 1 or 2 OH groups and at least 6 O atoms, were (a), (b) and (c) form more than 80 wt. % of the monomers incorporated in (I).
