Publication number: 20120165770Abstract: A stimulation material is partially bonded to a pressure-sensitive adhesive to form a stimulation blend. The stimulation blend, with or without pressure-sensitive adhesive, may be juxtaposed between two substrates to form a stimulation composite. When the pressure-sensitive adhesive is present within the stimulation composite, there are regions of the adhesive that do not contain a significant amount of stimulation material. By arranging regions of stimulation blend with respect to the pressure-sensitive adhesive regions, a pattern defined by the stimulation blend is formed. This pattern may deliver a stimulation effect that is at least as effective as using one-hundred percent stimulation blend within the stimulation composite, it not more effective. The stimulation composite may be cut into countless varieties of pledget shapes for use in personal-care absorbent articles.Type: ApplicationFiled: December 28, 2010Publication date: June 28, 2012Inventors: Peiguang Zhou, Kenneth B.

Publication number: 20120040185Abstract: Polylactic acid fibers formed from a thermoplastic composition that contains polylactic acid and a polymeric toughening additive are provided. The present inventors have discovered that the specific nature of the components and process by which they are blended may be carefully controlled to achieve a composition having desirable morphological features. More particularly, the toughening additive can be dispersed as discrete physical domains within a continuous phase of the polylactic acid. These domains have a particular size, shape, and distribution such that upon fiber drawing, they absorb energy and become elongated. This allows the resulting composition to exhibit a more pliable and softer behavior than the otherwise rigid polylactic acid. Through selective control over the components and method employed, the present inventors have discovered that the resulting fibers may thus exhibit good mechanical properties, both during and after melt spinning.Type: ApplicationFiled: August 13, 2010Publication date: February 16, 2012Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Vasily A. Topolkaraev, Peiguang Zhou, Gregory J. Wideman, Tom Eby, Ryan J. McEneany

Patent number: 7833369Abstract: The present invention is generally directed to webs, components, composites, and strands comprising re-activatable adhesive compositions, as well as health-and-hygiene products employing such webs, components, composites, and strands. By inputting energy to the web, component, composite, or strand (including, for example, an elastic web, component, composite, or strand) comprising a re-activatable adhesive composition, the adhesive is activated (i.e., rendered tacky) so that it can be used to join or adhere the web, component, composite, or strand to another material (or another location on the same web, component, composite, or strand). Generally, energy will be inputted to the adhesive in the form of infrared heat, heat, or ultrasonic energy, although any energy form may be used, so long as the energy is capable of activating the adhesive. Prior to activation, webs, components, composites, and strands comprising such re-activatable adhesives are convenient to handle because the adhesive is not yet tacky.Type: GrantFiled: December 14, 2005Date of Patent: November 16, 2010Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Peiguang Zhou, Gregory K.
