The use of polyether hydroxycarboxylate copolymers in textile manufacturing and treating processes. The polyether hydroxycarboxylate copolymer has the structure (see formula I) wherein M+ is a cation wherein M is independently selected from the group consisting of hydrogen, ammonia, alkali metals, alkaline earth metals, zinc, copper, organic amines, amino acids, and amino saccharides; R1 is the residue of an ethylenically unsaturated comonomer having at least one functional group which is selected from the group consisting of carboxylic acid, sulfonic acid and phosphonic acid; R2 and R3 are independently selected from the group consisting of hydrogen, and a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms; n is from about 2 to about 100; x1 and x2 are independently 0 or 1; a is from 0 to 100 mole percent; and b is from 100 to 0 mole percent, provided that (a + b) is 100 mole percent. The copolymers chelate heavy metal ions forming soluble complexes which help stabilize bleach, reduce scale, prevent redeposition of particulate soils, prevent deposition of metals, and disperse dyes.
