Patent number: 6299965Abstract: The invention relates to inflatable fabrics which comprise two separated and distinct fabric layers in discrete areas of such fabrics as well as C-shaped seam-producing materials to which such fabric layers are attached. The resultant inflatable fabric composite this includes inflatable areas separated, at least partially, by seamed barrier areas. This configuration will form “pillowed” structures within the target fabric upon inflation. Such seam-producing materials are incorporated within the two-layer structure as C-shaped peel seams in relation with the individual fabric layers. Upon inflation, the seams then act as shear seams which greatly increases the overall strength of the two-layer inflatable fabric. These shear seams thus provide a relatively effective manner of reducing air permeability within the entire fabric article. Such a fabric may be utilized in numerous and various applications wherein fabric inflation is desired or necessary.Type: GrantFiled: November 17, 1999Date of Patent: October 9, 2001Assignee: Milliken & CompanyInventor: Ramesh Keshavaraj

Patent number: 6296919Abstract: This invention relates to a cushioned floor covering article wherein the mat includes a tufted carpet placed on the top side of a foam rubber sheet and at least one foam rubber protrusion integrated within at least a portion of the bottom side of the foam rubber sheet. Such an article provides effective removal of moisture, dirt, and debris from the footwear of pedestrians through the utilization of a carpet pile component. Furthermore, the utilization of a foam rubber backing also allows for either periodic heavy duty industrial-scale laundering in such standard washing machines or periodic washing and drying in standard in-home machines, both without appreciably damaging the inventive floor covering article, such as a floor mat. Additionally, the presence of integrated foam rubber protrusions within the mat structure provides an effective cushioning effect for pedestrian comfort as well as a means to prevent slippage of the article from its contacted surface.Type: GrantFiled: August 13, 1999Date of Patent: October 2, 2001Assignee: Milliken & CompanyInventors: James N. Rockwell, Jr., Robert C. Kerr, William O. Burke, III

Patent number: 6294487Abstract: The present invention relates to an airbag fabric which is woven in such a manner as to possess a cover factor of less than about 1900 but which simultaneously, through the presence of a film (laminate) or coating, possesses an extremely low air permeability. The utilization of such a loosely constructed fabric within airbag cushions has heretofore not been possible, even with the application of standard airbag coatings (such as silicones) over the fabric surface since such coatings with not easily remain in contact over the loosely constructed fabric surface (i.e., the coating would leak through the fabric). The coupling of a low cover factor fabric with a laminate film (or with a coating wherein the cover factor is at least 1600), however, solves such a problem and permits the utilization of inexpensively produced woven fabrics within airbag applications.Type: GrantFiled: September 24, 1999Date of Patent: September 25, 2001Assignee: Milliken & CompanyInventor: Ramesh Keshavaraj
