Patent number: 10219953Abstract: A binder layer for a laminated wound dressing is brought into contact with a sheet coated with a pattern-coated adhesive sheet. As the binder layer is in contact with the pattern-coated adhesive sheet, a series of closed-loop cuts are made in the binder layer.

Publication number: 20110070420Abstract: A nonwoven is formed from one or more performance enhancing fibers together with one or more cellulosic fibers. The nonwoven could include low melting fibers for holding the nonwoven together on melting, and could include one or more optional fibers which impart a characteristic of interest to the nonwoven. The cellulosic fiber in the nonwoven is treated with fire resistant chemicals. The nonwoven has enhanced fire barrier performance, such as char elongation and char strength.Type: ApplicationFiled: October 18, 2010Publication date: March 24, 2011Applicant: TINTORIA PIANA US, INC.Inventors: Sang-Hoon Lim, Andrea Piana

Patent number: 7786032Abstract: The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) is used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive.Type: GrantFiled: September 16, 2008Date of Patent: August 31, 2010Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Peiguang Zhou, Timothy James Blenke
