Publication number: 20140272362Abstract: The present invention provides multicomponent thermoplastic fibers that are biodegradable and that are capable of forming strong bonds in air bonding processes. In various embodiments, the multicomponent fibers can include a first polymer component that includes a first aliphatic polyester, and a second polymer component also including an aliphatic polyester, wherein the first polymer component comprises at least a portion of an exposed surface of the multicomponent fiber. The first polymer component can be a fully amorphous polylactic acid and the second polymer component can be a semicrystalline polylactic acid. The multicomponent fiber can have cross-sectional area comprising the first polymer component and the second polymer component in about a 1:1 ratio, wherein the first polymer component and the second polymer component are configured in a sheath/core arrangement.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Applicant: Fiber Innovation Technology, Inc.Inventors: Jeffrey S.

Patent number: 8137811Abstract: Taggant fibers and methods of use provide for enhanced protection and security when the fibers are used in documents such as land titles, currency, passports and other documents of value. The taggant fibers consist of a minimum of two separate zones with each zone containing a different taggant to emit different wave lengths when excited. The taggants may consist of organic or inorganic compounds as are conventionally known and can be manufactured using for example polymeric materials which can be extruded during the fiber manufacturing process. Authentication of the fibers or documents containing such fibers can be readily viewed using conventional techniques.Type: GrantFiled: September 8, 2008Date of Patent: March 20, 2012Assignees: Intellectual Product Protection, LLC, Fiber Innovation Technology, Inc.Inventors: Timothy P. Merchant, Jeffrey S. Dugan
