Abstract
A post mill or post manufacturing process for reducing wrinkle and crease problems in fabric articles is provided. The process involves the domestic or commercial laundry application of a phosphonate- and phosphinate-containing polycarboxylate cross-linking agent followed by at least partial curing of the cross-linking agent via the application of heat to the article. The present invention also includes an article of manufacture or product comprising the treatment composition, at least one container for the treatment composition and accompanying text instructing the user of the product on application of the treatment.
Claims12
