Abstract
Textile materials comprising polyester fibers having improved durable soil release characteristics are provided by padding the textile material with an effective amount of polymer solution comprising from about 0.05 to about 5 weight percent based on the weight of the solution of a sulfonated polyester polymer, and at least about 10 percent based upon the weight of the sulfonated polyester polymer of a water-soluble salt in which the cation moiety of the salt is a polyvalent metal ion of magnesium, zinc, or calcium. The aqueous solution is padded onto the textile material in an amount sufficient to provide at least about 0.05 weight percent solids on the textile material, such solids being a combination of the sulfonated polyester and the salt constituent. The resulting wet textile material may thereafter be dried to remove substantially all of the water and thereafter the dry textile material may be heated to a temperature sufficient to heat set the fabric and cure the polymer containing the salt constituent.
