Patent number: 6029274Abstract: A protective garment without front facing seams. The protective garment contains a body piece composed of a single seamless sheet of material. The body piece has a right body side and a left body side. Each body side includes a first and second leg edge, a torso edge and a top body side edge extending approximately half-way across each body side from the respective torso edge. The body piece also includes a right sleeve portion and a left sleeve portion. Each sleeve portion has a first and second sleeve edge, and a top sleeve portion edge. Generally speaking, the garment's construction includes approximately five seams and a closure. The closure joins the torso edge of right body side to the torso edge of the left body side to form a resealable opening at a rear face of the garment. Sleeve seams join the first sleeve edges to the second sleeve edges on each sleeve portion and inseams join the first leg edges to the second leg edges on each body side.Type: GrantFiled: July 7, 1998Date of Patent: February 29, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Debra Nell Welchel, Alan Edward Wright, Jay Amedee Poppe, Vivian Gray

Patent number: 6022818Abstract: Disclosed herein is an entangled nonwoven composite made from absorbent fibers such as wood pulp fibers and matrix fibers such as polyolefin staple fibers. The absorbent fibers are entangled with the matrix fibers in such a manner so that the composite has an absorbent-rich side and a matrix-rich side. Intermediate the two exterior sides there is an entangled interior portion made from a mixture of the absorbent and matrix fibers. The composite is particularly well-suited for use in multifunctional handling of fluids such as, for example, body fluids which are absorbed by personal care absorbent articles. The matrix fiber portion of the composite acts as a fluid intake region while the absorbent fiber portion acts as a fluid retention region and the portion of the composite intermediate the two exterior surfaces acts as a fluid transfer region.Type: GrantFiled: April 2, 1996Date of Patent: February 8, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Debra Nell Welchel, Eric Scott Kepner, Crystal Sutphin Leach
