Patent number: 6779330Abstract: An antimicrobial, cut-resistant composite yarn which has a core member including at least one cut-resistant strand, a cover member including at least one strand wrapped around and enclosing the core member, wherein at least one strand in either the core member or the cover member is treated with and incorporates an antimicrobial compound. The yarn can be used to fabricate cut-resistant garments, such as gloves, worn by meat cutters and others who work with knives, saws and other sharp implements. The antimicrobial effect reduces bacteria, mold and fungi growth on the garments between washings.Type: GrantFiled: October 31, 2000Date of Patent: August 24, 2004Assignee: World Fibers, Inc.Inventors: Dean Riley Andrews, Gregory V. Andrews, John D. Simmons

Publication number: 20040157520Abstract: A fabric material includes one or more non-fluorescent or non-illuminative fibers and one or more fluorescent or illuminative fibers engaged or woven or entangled or intermingled with each other, to solidly engage the fluorescent fibers in the non-fluorescent fibers, and to prevent the fluorescent fibers from being disengaged from the non-fluorescent fibers. The fluorescent fibers may reflect the lights, or may absorb the lights in the day time, and to generate fluorescence or illuminative lights in the night or in the dark environment, and thus for allowing the users to be seen in the dark environment, to prevent accidents.Type: ApplicationFiled: February 10, 2003Publication date: August 12, 2004Inventors: Chin Chuan Huang, Chi Yuan Chang, Poen Chen

Publication number: 20030159768Abstract: The present invention is directed to a hybrid cabled cord comprising: at least two yarns having different properties and an unbalanced configuration wherein the hybrid cabled cord has improved tensile strength retention. In a preferred embodiment one of the two yarns comprises polyethylene terephthalate and the second of at least two yarns comprises polyethylene naphthalate and the coring level is between about 3% to about 15%. The present invention is also directed to a process for making a hybrid cabled cord comprising the steps of supplying at least two yarns having different properties to a direct cabler, and cabling the at least two yarns using the direct cabler to achieve a hybrid cabled cord having a coring level which is not zero. The present hybrid cabled cord may be used in tire cord for rubber reinforcement in passenger car tires, van tires, light truck tires, or motorcycle tires.Type: ApplicationFiled: March 25, 2003Publication date: August 28, 2003Inventors: Jean-Francois Fritsch, Paul Rugraff, Jeffrey Allen Funderburk
