Abstract
An aqueous fabric treating composition for improving the particulate redeposition properties, as well as the soil release properties, of a polyester textile material during a laundering process is provided in which the aqueous fabric treating composition contains, as essential ingredients, from about 0.0001 to about 10 weight percent of a cellulose ether soil release agent and an effective amount of an anti-redeposition agent selected from the group consisting of citric acid and acidic acrylic copolymers containing from about 10 weight percent to about 90 weight percent of the acid constituent, such being calculated as acrylic acid. The effective amount of the anti-redeposition agent is that amount sufficient to provide a ratio of the anti-redeposition agent to the cellulose ether soil release agent of from about 1.5:1 to about 10:1. A method for improving the particulate redeposition properties of polyester textile materials during the laundering process, while providing desirable soil release properties to such materials, as well as the products so produced, is also provided.
