Patent number: 12377001Abstract: A hollow fiber that extending along at least a portion of the fiber along a longitudinal axis thereof and is defined by an interior wall is provided. Through selective control over the manner in which it is formed, the present inventors have discovered that the hollow fiber can exhibit a unique combination of a high void fraction and small fiber size that makes it particularly suitable for use in certain applications, such as in nonwoven webs for absorbent articles.Type: GrantFiled: December 14, 2021Date of Patent: August 5, 2025Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Eric E. Lennon, John H. Conrad, Douglas J. Hulslander, David W. Hall

Patent number: 11083816Abstract: A nonwoven web that contains a plurality of fibers formed from a polyolefin composition is provided. The polyolefin composition contains a rigid propylene polymer that has a relatively high melting temperature and modulus of elasticity, which can provide good strength and durability to the nonwoven web. The polyolefin composition also contains a ductile propylene polymer that has a relatively high melt flow index, which can help achieve relatively fine fibers that minimize the stiffness of the web. In addition to a rigid and ductile polymer, the polyolefin composition also contains a slip additive (e.g., fatty acid derivative). Among other things, such an additive can even further enhance the overall softness of the composition.Type: GrantFiled: November 18, 2014Date of Patent: August 10, 2021Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Mark G. Kupelian, Lei Huang, John H. Conrad, Jeffrey J. Krueger, Ray A. Sterling
