Patent number: 4906503Abstract: A banner including a bonded nonwoven polyolefin film-fibril sheet having front and back surfaces and having two side edges intersecting top and bottom edges to define four corners. The side edges are generally linear and are folded-over onto the back surface of the sheet and secured with double-faced adhesive tape to form a laminated edgefold with the double-faced adhesive tape sandwiched between two layers of the sheet. The front surface of the sheet has at least a first coating of surface-sealing polymer and means are provided adjacent each corner for attaching cords to the edgefold for hanging the banner.Type: GrantFiled: August 30, 1988Date of Patent: March 6, 1990Assignee: E. I. DuPont de Nemours and CompanyInventors: Danilo O. De La Cruz, Harold M. McCabe, Jeffrey P. Shawcross

Patent number: 4880879Abstract: The present invention is a composite material and a process for making the same. The composite material comprises a thermoset or condensation polymeric material into which has been dispersed high molecular weight polyethylene particles which have been surface treated to have a surface tension of at least 40 dyne/cm at 20.degree. C. The polyethylene particles are dispersed into the thermoset or condensation polymeric material in a concentration range of 2-80 wt % and preferably from 4-66 wt % of the total composite. The resultant composite material exhibits high abrasion resistance and can easily be molded into end products.Type: GrantFiled: February 18, 1988Date of Patent: November 14, 1989Assignee: Air Products and Chemicals, Inc.Inventor: Bernard D. Bauman

Patent number: 4861652Abstract: The present invention provides a distinctive absorbent article which includes a backsheet layer which delimits at least one waistband portion of the article. A substantially liquid-permeable topsheet layer is located in facing relation with an inner surface of the backsheet layer, and an absorbent body is located between the topsheet layer and the backsheet layer. An elastic member, which is connected to the waistband portion, is composed of an elastomeric, nonwoven fibrous web material, and is constructed and arranged to shirr the waistband portion.Type: GrantFiled: October 13, 1987Date of Patent: August 29, 1989Assignee: Kimberly-Clark CorporationInventors: Mary E. Lippert, Kenneth M. Enloe, Debra J. Koch, Thomas H. Roessler, Patrick A. Pazdernik
