Patent number: 7012033Abstract: Wash-durable fluorochemical-containing textile and/or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided. Such treatments surprisingly impart these two simultaneous effects to target fabrics and/or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release/moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release/moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release/moisture wicking properties.Type: GrantFiled: January 24, 2003Date of Patent: March 14, 2006Assignee: Milliken and CompanyInventors: Heather J. Hayes, Xinggao Fang, Sidney S. Locke, Jr.

Publication number: 20040253410Abstract: A surface covering element adapted for disposition in covering relation to a support surface. The surface covering element includes a show surface adapted to project away from the support surface when the surface covering element is disposed across the support surface and an underside adapted to project towards the support surface when the surface covering element is disposed across the support surface. A friction enhancing coating composition is disposed in coated relation across the underside at an effective level to enhance sliding friction of the surface covering element such that the surface covering element exhibits a degree of lateral grip cross across the support surface. The friction enhancing coating composition does not permanently stick to the support surface.Type: ApplicationFiled: April 19, 2004Publication date: December 16, 2004Inventors: Kenneth B.

Patent number: 6812172Abstract: In a preferred embodiment, the present process involves subjecting a fabric comprised of conjugate yarns to an acidic treatment, which degrades a portion of one component of the conjugate yarns and to dyeing. The acid treatment, given certain reaction kinetics, removes a portion of the polyamide element of the conjugate filament. The at least partial removal of the polyamide component results in a fabric has enhanced dyed appearance, especially when dyed a dark shade. In an alternate embodiment, the fabric may also be treated with a basic solution to improve its moisture transport properties.Type: GrantFiled: February 12, 2002Date of Patent: November 2, 2004Assignee: Milliken & CompanyInventors: Heather J.
