Publication number: 20100092719Abstract: A flocked transfer is produced by applying a release agent to a release sheet, and then applying the flocking to a release agent. Unlike the traditional method, a binder and thermoplastic hot melt film is applied to the back of the flock. The transfer, which is essentially release sheet, is then applied to a substrate, such as item of clothing, a rubber pad, etc., by positioning a sheet of thermoplastic hot melt film on the substrate; placing the transfer on the hot melt with the flock in contact with the hot melt film, and applying heat and pressure. The heat melts the thermoplastic hot melt film to bind the flock to the substrate and binds the flocking together. This method reduces the cost involved in producing flocked articles, especially for articles produced on a continuous basis.Type: ApplicationFiled: December 11, 2009Publication date: April 15, 2010Applicant: HIGH VOLTAGE GRAPHICS, INC.Inventor: Louis Brown Abrams

Patent number: 7464510Abstract: Connectors for joining adjacent modular floor covering units. The connectors include a film and an adhesive layer coated on one side of the film. To install tiles using the connectors, a first tile is placed on the floor and a connector is positioned so that the adhesive layer faces upward and does not contact the floor. The connector is typically positioned so that only a portion of the adhesive layer adheres to the underside of the tile, leaving the remainder of the connector extending from the underside of the tile. Tiles are then positioned adjacent the first tile so that a portion of the connector adheres to the adjacent tiles. In this way, the connectors span adjacent tile edges. The tiles are assembled on a underlying flooring surface without the need to attach them to the floor surface. Rather, the tiles are linked to each other with the connectors, so that the tiles create a floor covering that “floats” on the under lying floor surface.Type: GrantFiled: December 21, 2004Date of Patent: December 16, 2008Assignee: Interface, Inc.Inventors: Graham A.

Patent number: 7462385Abstract: The present invention relates to an improved disposable cleaning sheet for removing debris, especially hair from a non-smooth or rough surface, especially fibrous type surfaces such as carpeting or upholstery. The cleaning sheets comprise a fibrous substrate and a plurality of protrusions extending from strand elements embedded within fibrous substrate. The cleaning sheets use the protrusions to dislodge the debris from the surface being cleaned, and the fibrous substrate captures the dislodged debris without a backing for the protrusions interfering with the particle capture of the fibrous substrate. Further, the protrusions are firmly embedded within the fibrous substrate such that they cannot be dislodged from the substrate in use.Type: GrantFiled: October 14, 2003Date of Patent: December 9, 2008Assignee: 3M Innovative Properties CompanyInventors: Jayshree Seth, Ronald W. Ausen, Kim C. Sachs

Publication number: 20080220701Abstract: A method for making a polishing pad includes providing a non-woven fabric made of a plurality of fibers. The non-woven fabric is submerged with a polymer resin solution. The polymer resin submerged in non-woven fabric is cured to form a porous polymer having an outer face adapted for polishing a workpiece. The outer face of the porous polymer is finished to form a polishing pad with a plurality of naps on the outer face. The plurality of naps on the outer face have a density ranging from 1.0 to 2.0 g/cm3, and the plurality of naps on the outer face have a length ranging from 50 to 600 ?m.Type: ApplicationFiled: May 20, 2008Publication date: September 11, 2008Inventors: Chung-Ching Feng, Chen-Hsiang Chao, I-Peng Yao, Yung-Chang Hung

Patent number: 7393576Abstract: The articles of the present invention are directed to flocked articles having a plurality of conductively coated concentric multi-component flock fibers. The flock fibers are: adhered between a release adhesive layer and a permanent adhesive layer; orientated substantially perpendicular to the release adhesive and permanent adhesive layers; and maintained substantially parallel to one another along their entire length. In one embodiment the multi-component flock fibers are bi-component fibers having an outer polymer composition of poly(cyclohexylene-dimethylene terephthalate).Type: GrantFiled: January 14, 2005Date of Patent: July 1, 2008Assignee: High Voltage Graphics, Inc.Inventor: Louis Brown Abrams

Patent number: 7390552Abstract: A flocked transfer is produced by applying a release agent to a release sheet and then applying the flocking to the release agent. Unlike the traditional method, a binder and hot melt film is not applied to the back of the flock. The transfer (which is essentially a flocked release sheet) is then applied to a substrate (i.e., an item of clothing, a rubber pad, etc.) by positioning a sheet of thermosetting hot melt film on the substrate; placing the transfer on the hot melt film with the flock in contact with the hot melt film; and applying heat and pressure. The heat melts the thermosetting hot melt film to bind the flock to the substrate and binds the flocking together. This method reduces the costs involved in producing flocked articles, especially for articles produced on a continuous basis.Type: GrantFiled: September 23, 2003Date of Patent: June 24, 2008Assignee: High Voltage Graphics, Inc.Inventor: Louis Brown Abrams

Publication number: 20080116129Abstract: A tufted nonwoven includes a face material which tufts a bonded nonwoven having a mixture of a plurality of bicomponent filaments 1 with a plurality of bicomponent filaments 2. At least bicomponent filaments 1 have component 11 and component 12. Component 11 exhibits a melting temperature Tm(11), and component 22 of the bicomponent filaments 2 exhibits a melting temperature Tm(22). Component 12 exhibits a melting temperature Tm(12), and component 21 of the second bicomponent filaments exhibits a melting temperature Tm(21), and Tm(12) is higher than Tm(21). The melting temperatures of components 11 and 22 and the melting temperatures of components 12 and 21 obey a relationship in which Tm(11) and Tm(22)>Tm(12)>first Tm(21) and optionally wherein the face material is bonded to bicomponent filaments 2 by a solidified melt of component 21. Also described are a bonded nonwoven and methods for their manufacture.Type: ApplicationFiled: January 25, 2006Publication date: May 22, 2008Applicant: Colbond B.V.Inventors: Maarten Oosterbroek, Jan Dijkema, Edze Jan Visscher
