Patent number: 7931957Abstract: Described are fiber materials having improved malodor scavenger properties and a process for the manufacture of said materials. In particular, described are fiber materials usable in the manufacture of disposable or washable diapers, incontinent products, sanitary napkins and other such hygiene and personal care articles with improved malodor scavenger properties, and to methods of manufacturing such materials. It has been found that the incorporation of, especially nanosized, metal particles and/or a cyclodextrin material into fibers creates a “reactive” material having excellent malodor scavenging properties. More specifically, it has been found that the presence of nanosized metal or metal alloy particles and/or a cyclodextrin material in a fiber material, preferably a synthetic polymer material and more preferably a synthetic thermoplastic polymer fiber material leads to fiber materials or nonwovens having odor-controlling properties.Type: GrantFiled: November 21, 2008Date of Patent: April 26, 2011Assignee: Cellresin Technologies, LLCInventors: Will Wood, Neil Beaverson

Publication number: 20050182234Abstract: Volatile organic compound or other materials are produced in the thermoplastic manufacture of thermoplastic polyester beverage containers. Such materials can be eluted into beverages such as carbonated beverages, sparkling or still water from the polyester. Such thermoplastic polyester resins can be manufactured with a material that can prevent the formation of, or react with, and absorb volatile by-products during the formation of thermoplastic preforms or containers from the thermoplastic pellet or chip. Further, as the preform is blown into a polyester container, the active materials of the invention prevent the generation of additional undesirable volatile materials. Lastly, the scavenger material can act as a barrier that prevents transport of materials from the exterior of the container into the container contents.Type: ApplicationFiled: March 2, 2005Publication date: August 18, 2005Applicant: Cellresin Technologies, LLCInventors: Willard Wood, Neil Beaverson, Phillip Lawonn, Xiaoyan Huang
