Abstract:
A processing aid for use in a textile manufacturing or treating process, said processing aid comprises a polyether hydroxycarboxylate polymer or copolymer having the structure wherein M+ is a cation having a +1 charge, or M+ and M+ together are a single cation having a +2 charge 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, with the proviso that the sum of x1 and x2 is at least 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, wherein said processing aid is present in an amount of from about 0.001 to about 50 weight percent, based on the weight of the solution or dispersion used in the textile process.
