Patent number: 6398910Abstract: Tissue products such as facial tissue, bath tissue, paper towels and the like are wet molded and dried using a through-air-drying fabric which has a three dimensional, sculptured, textured background accentuated with decorative signature patterns. The textured background is woven into the fabric. The decorative patterns are created by using a smooth polymeric substance or by yarn stitches. The decorative patterns on the through air drying fabric provide enhanced aesthetics, while the textured background provides improved properties such as absorbent capacity, absorbent rate, stretch, flexibility, drape, bulk, and hand feel when used in tissue making.Type: GrantFiled: December 22, 2000Date of Patent: June 4, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Mark Alan Burazin, Kai F.

Patent number: 6017417Abstract: Throughdried tissue products such as facial tissue, bath tissue, and paper towels are made using a throughdrying fabric having from about 5 to about 300 machine direction impression knuckles per square inch (per 6.45 square centimeters) which are raised above the plane of the fabric. These impression knuckles create corresponding protrusions in the throughdried sheet which impart a significant amount of cross-machine direction stretch to the sheet. In addition, other properties such as bulk, absorbent capacity, absorbent rate and flexibility are also improved.Type: GrantFiled: October 7, 1997Date of Patent: January 25, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Greg Arthur Wendt, Kai F.

Patent number: 5429686Abstract: A throughdrying fabric for the drying section of a papermaking machine is disclosed in several embodiments. In each embodiment, the fabric has a load-bearing layer and a sculpture layer. The sculpture layer is characterized by impression MD knuckles, in the present instance formed as warp knuckles floating over a plurality of shutes but positioned substantially above the tops of the lowest shute knuckles in the load-bearing layer so as to provide machine direction knuckles projecting in the sculpture layer. Methods of weaving the fabric are disclosed using a standard fourdrinier loom. The loom may embody an auxiliary jacquard mechanism which is effective to control the impression warps in the sculpture level to produce a wide variety of patterns of impression knuckles which, in turn, produce an image on the pulp web which the throughdrying fabric carries through the machine.Type: GrantFiled: April 12, 1994Date of Patent: July 4, 1995Assignee: Lindsay Wire, Inc.Inventors: Kai F. Chiu, David T. Evans, Antonius F. Rietvelt, Greg A. Wendt

Patent number: 5379808Abstract: A multi-ply forming fabric for use at the wet end of a papermaking machine for receiving wet pup having a substantial portion of recycled paper fibers. The forming fabric cannot be characterized as either a conventional double-layer or triple-layer fabric. The fabric has an independent top ply comprising a self-sustaining weave of warp yarns and shute yarns, and a bottom side comprising a series of dependent shute yarns interwoven with the top ply by binder warp yarns. The binder warp yarns are illustrated as single and double round yarns, and single ovate yarns. The fabric has a reduced caliper, larger internal fiber interstices and substantial projected open areas which trap fewer contaminants and allow the fabric to be more easily cleaned.Type: GrantFiled: September 8, 1993Date of Patent: January 10, 1995Assignee: Lindsay Wire, Inc.Inventor: Kai F. Chiu

The forming fabric cannot be characterized as either a conventional double-layer or triple-layer fabric. The fabric has an independent top ply comprising a self-sustaining weave of warp yarns and shute yarns, and a bottom side comprising a series of dependent shute yarns interwoven with the top ply by binder warp yarns. The fabric has a reduced caliper, larger internal fiber interstices and substantial projected open areas which trap fewer contaminants and allow the fabric to be more easily cleaned than conventional fabrics.Type: GrantFiled: February 6, 1992Date of Patent: June 15, 1993Assignee: Lindsay Wire, Inc.Inventor: Kai F. Chiu

Patent number: 4967805Abstract: A forming fabric for use in papermaking machines for making tissue products in which the fabric is a three-ply fabric. The upper ply has its machine direction (MD) filaments arranged in groups so that wide channels are provided through the ply between the groups and narrow channels are provided through the ply within the groups. Cross direction (CD) filaments in the upper ply provide CD knuckles spanning across the channels to provide a gridwork for supporting fibers separated from the water of the slurry deposited on the forming fabric, the fibers having a greater density in bands overlying the wide channels than in the intermediate bands overlying the narrow channels. The lower ply is a porous fabric which further controls the flow of the water discharged from the pulp through the upper ply. The two plies are interconnected by integrated binder filaments which cooperate to maintain the groupings of the MD filaments in the upper ply.Type: GrantFiled: May 23, 1989Date of Patent: November 6, 1990Assignee: B.I. Industries, Inc.Inventors: Kai F. Chiu, Antonius F. Rietvelt, James S. Rugowski, Greg A. Wendt

Patent number: 4942077Abstract: Creped tissues having improved perceived softness and appearance are made from tissue webs having at least a machine direction broken line pattern of individual densified areas containing higher mass concentrations of fibers. The broken line pattern of densified areas creates a pleasing appearance and influences the creping to provide a more uniform crepe and hence improved tissue softness.Type: GrantFiled: May 23, 1989Date of Patent: July 17, 1990Assignee: Kimberly-Clark CorporationInventors: Greg A. Wendt, Kimberly K. Underhill, James S. Rugowski, Bernhardt E. Kressner, Kai F. Chiu

Patent number: 4705601Abstract: A wire former comprising a structural framework, a headbox for holding and dispensing the pulp slurry, a breast roll, a couch roll, a forming fabric belt extending endless between the breast roll and the couch roll in a straight run, and drainage elements and suction devices underlying said straight run for extracting liquid from the slurry. The forming fabric is a multi-ply fabric, the uppermost ply being a self-sustaining weave with monofilament warp yarns of a given diameter interwoven with shute yarns, the lowermost ply being a weave with a series of generally ovate warp yarns having a vertical dimension generally equal to the diameter of the warp yarns of the uppermost ply, interwoven with shute yarns. The ovate warp yarns have a horizontal width in the shute direction substantially greater than their vertical dimension. Binder shute yarns interconnect the upper and lower plies by being interwoven with the upper and lower plies so as to be contained within the body of the multi-ply fabric.Type: GrantFiled: February 5, 1987Date of Patent: November 10, 1987Assignee: B.I. Industries, Inc.Inventor: Kai F. Chiu
