Patent number: 6686303Abstract: An improved nonwoven web composite is formed by combining splittable bicomponent thermoplastic filaments with a component selected from other fibers and particles. The bicomponent filaments include distinct regions of first and second incompatible polymers extending the length of the filaments. After the bicomponent filaments are combined with the other fibers and/or particles, the bicomponent filaments are caused to split lengthwise along boundaries between the regions of different polymers, resulting in a web or matrix of finer filaments which entrap, ensnare and contain the other fibers and/or particles within the web or matrix. The nonwoven web composite is particularly useful for making absorbent articles, which require durability and optimum levels of absorbent fibers and/or particles.Type: GrantFiled: November 13, 1998Date of Patent: February 3, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Bryan David Haynes, Billy Dean Arnold, Justin Max Duellman, Ryan Clinton Frank, Jeffrey Lawrence McManus, Charles Allen Smith, Ty Jackson Stokes, Kevin Edward Smith, Darryl Franklin Clark, Debra Jean McDowall, Samuel Edward Marmon, Christopher Cosgrove Creagan, Xin Ning, David Lewis Myers

Patent number: 5935512Abstract: Improved equipment and method for spinning filaments for nonwovens using an integral spinbank including one or more spinplates producing filament bundles separated by one or more central conduits for quench air. Embodiments include high velocity quench air driven into the central conduit or quench air blown or drawn in from outside the filaments into the central conduit. Means may also be provided for removal of undesired waxes and/or other condensates through a central exhaust removal using the central conduit. As quench air velocity is increased through the central conduit, the streams tend to improve total quench flow by deflecting opposing flows into a uniform stream. Other variations include division of quench air into flow zones that may be independently controlled and varying the angle of quench air flow and/or the spinplates to maintain separation distance between quench air and filament bundles.Type: GrantFiled: December 18, 1997Date of Patent: August 10, 1999Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Bryan David Haynes, Kevin James Kastner, Jark Chong Lau, Samuel Edward Marmon, Charles John Morell, Stephen Harding Primm, Thomas Gregory Triebes
