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.

Publication number: 20040022994Abstract: An improved cushioned carpet fabric is provided. The cushioned carpet comprises a primary carpet having a primary base and a plurality of pile-forming yarns projecting outwardly from one side. A layer of reinforcement material is bonded to the primary base on the side opposite the pile forming yarns. The reinforcement layer is adjacent to and embedded in, a cushion layer of a polymer such as a polyurethane. There is preferably no additional adhesive between the cushion layer and the layer of reinforcement material. An apparatus and process for forming the cushioned carpet fabric are also provided.Type: ApplicationFiled: August 5, 2002Publication date: February 5, 2004Inventors: Kenneth B. Higgins, N.

Patent number: 6544621Abstract: Floor covering products, such as carpets, carpet tiles, floor mats, and the like, which comprise very specific antimicrobial adhesive latex formulations therein are provided. Such formulations comprise, as the only antimicrobial active ingredients, certain inorganic antimicrobial compounds, such as, preferably, silver-containing ion-exchange, glass, and/or zeolite compounds. Such latexes exhibit excellent adhesive and antimicrobial qualities and, since they do not contain any added organic bactericides (and thus no bactericide VOCs), do not release any such organic bactericides upon exposure to high processing temperatures.Type: GrantFiled: September 1, 2000Date of Patent: April 8, 2003Assignee: Milliken & CompanyInventors: Robert L. Schuette, John G. Lever, N. David Sellman, Jr.

Patent number: 6342212Abstract: Broadly defined adhesive latex formula s exhibiting antimicrobial properties. Such formulations comprise certain antimicrobial compounds, such as, preferably, metal-containing ion-exchange and/or zeolite compounds, are provided. The inventive latex formulations must also exhibit substantially uniform characteristics (such a similar viscosity and/or appearance throughout) in order to provide a functionally and aestheticially pleasing formulation for utilization within any number of applications. In order to provide such an inventive latex formulation, it has been found that compounding of all the base ingredients (polymer, antimicrobial agent, fillers) must be undertaken prior to the final thickening step, which ultimately produces the desired latex. The specific method of producing such formulations is also encompassed within this invention.Type: GrantFiled: September 1, 2000Date of Patent: January 29, 2002Assignee: Milliken & CompanyInventors: Robert L. Schuette, John G. Lever, N. David Sellman, Jr.
