Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling.Type: ApplicationFiled: January 5, 2004Publication date: July 15, 2004Inventors: Brian G.

The extensible nonwoven material is further selectively attached to the clastomeric film by a plurality of thermal point bonds. The intermittent adhesive bonds cover a greater percentage of an interfacial plane between the extensible nonwoven material and the elastomeric film material than the thermal point bonds. A process for making the extensible laminate is also disclosed.Type: ApplicationFiled: November 27, 2002Publication date: May 27, 2004Inventors: Michael Tod Morman, Prasad Shrikrishna Potnis, Gregory Todd Sudduth, Leslie Warren Collier, David Michael Matela, Randall James Palmer, Sjon-Paul Lee Conyer, Charles John Morell, Rasha Wafik Zaki Guirguis

Patent number: 6720063Abstract: An elastically stretchable composite sheet includes an elastically stretchable first web and an inelastically stretchable second web of thermoplastic synthetic resin fiber which is intermittently bonded to the first web in a y-direction. Component fiber of the second web has its cress-section cut in a direction orthogonal to the y-direction defined by a width w and a height h dimensioned to be at a ratio h/w less than 0.5. The composite sheet having such a structure improve its flexibility.Type: GrantFiled: August 30, 2001Date of Patent: April 13, 2004Assignee: Uni-Charm CorporationInventors: Toshio Kobayashi, Hiroki Goda

Patent number: 6663737Abstract: A core crush resistant prepreg for use in making a fiber reinforced composite panel structure is provided. The prepreg comprises a woven fabric consisting essentially of carbon fiber tow strands impregnated with a hardenable polymeric resin composition. Typically the fabric has an areal weight of from about 180 to about 205 grams per square meter. The prepreg has an average fiber tow aspect ratio of less than about 15.4, a prepreg thickness of at least about 0.245 mm, and a prepreg openness of at least about 1.2 percent but less than about 6.0 percent. Preferably, the resin composition is predominantly viscous in nature and has a tan &dgr; value of between 0.9 and 2.0 at an elevated temperature between 70° C. and 140° C., and an average epoxy functionality of greater than 2.0. A method for evaluating core crush resistance properties of a prepreg is also provided.Type: GrantFiled: June 7, 2001Date of Patent: December 16, 2003Assignee: Hexcel CorporationInventors: Hao-Ming Hsiao, Shaw Ming Lee, Robert Albert Buyny, Cary Joseph Martin

Publication number: 20030096114Abstract: Fibers or filaments made by using a spinneret orifice having a regular polygonal cross-section. Melt-spinnable thermoplastic polymer is melted and extruded through a spinneret orifice having a regular polygonal cross-section to form molten filaments. The molten filaments are then solidified, and optionally are subsequently subjected to stretching and false twisting processes.Type: ApplicationFiled: October 29, 2002Publication date: May 22, 2003Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Lien-Tai Chen, Ting-Tsiu Chen, Wei Hu

Publication number: 20030068948Abstract: An industrial fabric used in the form of an endless fabric belt to form and convey a nonwoven fiber web during the manufacture of a nonwoven fabric has a web-supporting surface which includes rough-surface yarns which inhibit movement, namely, slippage, of the nonwoven fiber web relative to the web-supporting surface. Preferably, the rough-surface yarns make long floats in one or both directions, that is, lengthwise and/or crosswise, on the web-supporting surface.Type: ApplicationFiled: October 5, 2001Publication date: April 10, 2003Inventors: Scott Sheldon Smith, Paul Allen Zimmerman, Mark Joseph Levine
