Patent number: 6777056Abstract: Composite nonwoven webs are provided having two distinct regions extending adjacent one another in the machine direction of the web; the first region is formed from first continuous filaments and the second region is formed from second continuous filaments. The interface of the first and second region is formed from a mixture the first and second continuous filaments in a confluent relationship with one another and such that the two distinct regions form a unitary nonwoven web. The respective first and second regions can have distinct physical attributes as a result of utilizing first and second filaments which are different from one another. The first and second continuous filaments can vary with respect to average fiber denier, cross-sectional shape, cross-sectional configuration, polymer composition, crimp level, and additive composition.Type: GrantFiled: October 12, 2000Date of Patent: August 17, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Lavada Campbell Boggs, Kevin George Hetzler, Glen Thomas Mildenhall, Michael Tod Morman, Dan Kenneth Schiffer, Susan Elaine Shawver, Sandy Chi-Ching Tan

Patent number: 6348258Abstract: A breathable film having improved processing properties and reduced cost includes a breathable film-forming layer composition including a matrix polymer, a particulate organic filler, and a compatibilizer. The particulate organic filler is incompatible with the matrix polymer and tends to agglomerate when mixed with the matrix polymer alone. The compatibilizer achieves thermodynamic equilibrium between the matrix polymer and filler within a defined filler particle size range suitable for producing stretched breathable film. The film processes more easily than breathable films containing inorganic fillers, and is less expensive to manufacture.Type: GrantFiled: March 12, 1999Date of Patent: February 19, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Vasily Aramovich Topolkaraev, Kevin Matthew Harrington, Glynis Allicia Walton, Sandy Chi-Ching Ying, Kevin George Hetzler
