Patent number: 6793309Abstract: A process for coloring substrates, using the application of liquid colorants, in which the assignment of color is done on a pixel-by-pixel basis, and corresponding products. Relatively large areas of a substrate may be given the appearance of being uniformly colored by successively replicating or tiling a group of individually colored pixels comprising a repeating unit (i.e., a superpixel) across the substrate surface. The repeating unit is constructed in such a way that if a colorant application error develops, causing one or more pixels within the repeating unit to be colored incorrectly or incompletely, the overall arrangement of the pixels within the repeating unit will render such error less visually apparent when viewed on the substrate.Type: GrantFiled: May 3, 2002Date of Patent: September 21, 2004Assignee: Milliken & CompanyInventors: Jonathan C. McCay, Lisa Bailey, Richard Stoyles, Lou Herring Webster, John K. Gurr

Patent number: 6792329Abstract: A computer-assisted process for the design and placement of multi-colored patterns on absorbent substrates using a limited number of transparent process colorants is described. Through use of this system, a designer, working with a computer-aided design system, can generate and accurately represent on a computer monitor or similar display a multi-colored pattern, as that pattern would appear on a specified absorbent substrate, using coloring elements comprised of groups of multiple pixels in which process colors have been mixed in a controlled manner to expand the range of available colors, and to compensate for colorant delivery limitations that prevent the application of small, accurately metered quantities of colorant. Actuation instructions for a specific dye injection machine capable of patterning a moving textile substrate may be generated.Type: GrantFiled: August 22, 2001Date of Patent: September 14, 2004Assignee: Milliken & CompanyInventors: Louis W.

Patent number: 6695346Abstract: A polygon-shaped air bag for use in vehicle restraint system is constructed from two panels of different sizes, each of which is in the form of an n-sided equiangular polygon, where n may be five or greater but is preferably six or eight. The panels are cut from a blank which is comprised of fabric or other suitable material, then superimposed in concentric relation onto one another with the perimeter portions of the larger panel folded and adhesively secured to the corresponding perimeter portions of the smaller panel for the purpose of distributing the stresses of inflation and impact across an area wider than the conventional equatorial seam and transferring such stresses into shearing, rather than tensile forces. In a preferred embodiment, the width of the overlapping panel portion is equal to the distance between an edge of the smaller panel and a corresponding parallel edge of the larger panel, where the panels are superimposed in concentric relation to one another.Type: GrantFiled: April 23, 1999Date of Patent: February 24, 2004Assignee: Milliken & CompanyInventor: Ramesh Keshavaraj

Patent number: 6546605Abstract: A fabric having at least one hydraulically napped surface comprised of tangled fibers is disclosed. Because the fiber tangles are created from intact, undamaged fibers, fabric strength is not adversely affected by treatment. In addition, laundering enhances entanglement and the aesthetic qualities attributed to this fabric property: surface texture (hand), resistance to pilling, drapeability, and the like. These subjective characteristics have been quantified using values from the Kawabata Evaluation System. A process for creating such fabrics has also been disclosed. The fabric passes through one or two treatment zones in which high pressure fluids (e.g., water) are directed at the fabric surface as the fabric moves away from a support member. In the case of dual treatment zones, a substantially lower pressure is used in the second treatment zone.Type: GrantFiled: July 10, 2001Date of Patent: April 15, 2003Assignee: Milliken & CompanyInventors: Nathan B. Emery, Franklin S. Love, III, Mathias B. Richardson, Joseph E. Rumler, Karen H. Stavrakas

Patent number: 6120560Abstract: A method and apparatus for pattern dyeing of textile substrates in which the dyeing is done in two stages. In the first stage, a dye is uniformly applied in a manner that allows the dye to fix on contact. The uniformly dyed substrate is then moved under a series of spaced arrays, each array being associated with a separate color and being comprised of a plurality of individually controlled liquid dye applicators. Liquid dye of a given color is selectively applied through one or more dye applicators as the substrate passes under the array associated with that color. The applied dye remains unfixed until the substrate passes under all the arrays and the patterning is complete, whereupon all dye applied by the dye applicators is fixed by steaming or other appropriate application of energy to the substrate.Type: GrantFiled: March 8, 1999Date of Patent: September 19, 2000Assignee: Milliken & CompanyInventors: Scott C. Miller, Frank W. Teaster, Matthew R. Walker

Patent number: 5865933Abstract: An apparatus and method for creation of a textile fabric that has been patterned with a selective application of heat, which provides a carved portion in registry with a color change. The textile fabric includes a blend of fibers of a first polymer having a first color with fibers of a second polymer having fibers of a second color. The melting point of the first fibers exceeds that of the second fibers. When patterned with a selective application of heat that exceeds that of the second fibers but is less than that of the first fibers, the second fibers melt away leaving the first fibers with the first color dominating. In the uncarved areas, the resulting color is a blend of the first color and the second color.Type: GrantFiled: November 12, 1996Date of Patent: February 2, 1999Assignee: Milliken Research CorporationInventors: Brian Gerald Morin, Paul William Eschenbach, Howard Christy Willauer

Patent number: 5861044Abstract: An apparatus and method for selectively carving textile fabric by selectively applying chemicals containing a liquid repellent either alone or with other chemicals such as dye to a textile fabric and subsequently finishing said fabric. The textile fabric is then rewetted by the application of liquid. The printed areas containing liquid repellant remain dry and the areas without liquid repellent are selectively wetted out. The textile fabric is then subjected to pressurized heated gas which selectively carves the dry areas printed with liquid repellent leaving the wetted areas protected and uncarved. As an alternative embodiment, the yarns that make up a textile fabric can be individually treated with a liquid repellent prior to being formed into a textile fabric.Type: GrantFiled: December 5, 1996Date of Patent: January 19, 1999Assignee: Milliken Research CorporationInventor: Edward Leland Crenshaw
