Publication number: 20150056461Abstract: A film formed from a water-soluble polymer matrix containing a fragrance is provided. The film is water-sensitive so that upon contact with a sufficient amount of water, the matrix loses its integrity to increasingly expose the fragrance to the ambient environment for releasing its odor. The ability to incorporate a fragrance into the matrix is achieved by controlling the nature of the fragrance and polymer, the manner in which the matrix and fragrance are melt processed, etc. For example, the fragrance may be injected directly into the extruder and melt blended with the polymer to avoid the costly, time-consuming steps of pre-encapsulation or pre-compounding of the fragrance into a masterbatch. Furthermore, to balance the fragrance's ability to release the desired odor during use while minimizing the premature exhaustion of the odor during processing, the fragrance has a boiling point (at atmospheric pressure) of from about 125° C. to about 350° C.Type: ApplicationFiled: October 30, 2014Publication date: February 26, 2015Inventors: Sarah A. Funk, James Hongxue Wang

Publication number: 20150037524Abstract: A sustainable thermoplastic composition made by forming a mixture of virgin polypropylene and post-industrial-recycled material (PIR). The PIR may include a thermoplastic, elastomeric-polymer and a spunbond component. The mixture is melt-blended in an extruder. Extruded materials made from the mixture demonstrate little variance in the results of the IZOD Impact Test of materials containing 30 to 70 percent PIR, and a material containing 100 percent virgin polypropylene. In addition, the extruded materials containing 30 to 70 percent PIR demonstrate a substantially constant strain at yield, that strain at yield being substantially equal to that demonstrated by a material containing 100 percent virgin polypropylene.Type: ApplicationFiled: December 23, 2013Publication date: February 5, 2015Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Brent Merrik Thompson, James Hongxue Wang, Gregory James Wideman

Patent number: 7189888Abstract: This invention is a surge material having permanent storage properties that results in faster intake and greater saturation capacity and reduced fluid flowback. More specifically the invention is a surge material with a superabsorbent material printed on in a pattern of discrete regions. The objective of the invention is obtained by printing, or other known application process, a liquid superabsorbent precursor solution containing a crosslinkable composition onto a surge material and then curing the printed surge material to crosslink the polymers to get a surge material having discrete regions of superabsorbent material in the surge material. This invention is also useful in making an absorbent core of an absorbent article with improved strength, increased absorbency, and decreased shedding of superabsorbent material.Type: GrantFiled: December 21, 2001Date of Patent: March 13, 2007Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James Hongxue Wang, Jian Qin, Jayant Chakravarty, Fu-Jya Daniel Tsai, Roland Columbus Smith, Jr., Christopher Dale Fenwick, Palani Raj Ramaswami Wallajapet, D.

Patent number: 6958371Abstract: The present invention discloses water-soluble compositions comprising a blend of poly(ethylene oxide) and poly(vinyl alcohol) that have improved ductility over water-soluble compositions comprising poly(vinyl alcohol) alone. In one desirable embodiment of the present invention, the poly(ethylene oxide) component of the blend is grafted. Grafted poly(ethylene oxide) resins have improved processability and improved blend compatibility with poly(vinyl alcohol). Films comprising a melt blend of poly(vinyl alcohol) and grafted poly(ethylene oxide) have improved melt processability as well as other improved properties. Films comprising compositions of the present invention have improved ductility over films comprising poly(vinyl alcohol) alone while retaining much of the high strength and water solubility exhibited by such poly(vinyl alcohol) films.Type: GrantFiled: June 19, 2000Date of Patent: October 25, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James Hongxue Wang, David Michael Schertz
