Patent number: 9972224Abstract: Disclosed are fibers which contains identification fibers. The identification fibers can contain a plurality of distinct features, or taggants, which vary among the fibers and/or along the length of the identification fibers of the fibers, a fiber band, or. The disclosed embodiments also relate to the method for making and characterizing the fibers. Characterization of the fibers can include identifying distinct features, combinations of distinct features, and number of fibers with various combinations of distinct features to supply chain information. The supply chain information can be used to track the fibers, fiber band, or yarn from manufacturing through intermediaries, conversion to final product, and/or the consumer.Type: GrantFiled: June 24, 2015Date of Patent: May 15, 2018Assignee: Eastman Chemical CompanyInventors: Larry Wayne Renfro, Andrew Ervin McLeod, Humberto Collazo, Ernest Phillip Smith

Patent number: 9617685Abstract: A process of making a paper or nonwoven article is provide. The process comprising: a) providing a fiber furnish comprising a plurality of fibers and a plurality of binder microfibers, wherein the binder microfibers comprise a water non-dispersible, synthetic polymer; wherein the binder microfibers have a length of less than 25 millimeters and a fineness of less than 0.5 d/f; and wherein the binder microfibers have a melting temperature that is less than the melting temperature of the fibers; b) routing the fiber furnish to a wet-laid nonwoven process to produce at least one wet-laid nonwoven web layer; c) removing water from the wet-laid nonwoven web layer; and d) thermally bonding the wet-laid nonwoven web layer after step (c); wherein the thermal bonding is conducted at a temperature such that the surfaces of the binder microfibers at least partially melt without causing the fibers to melt thereby bonding the binder microfibers to the fibers to produce the paper or nonwoven article.Type: GrantFiled: April 10, 2014Date of Patent: April 11, 2017Assignee: Eastman Chemical CompanyInventors: Mark Dwight Clark, Keh Dema, Sungkyun Sohn, Ernest Phillip Smith, Chris Delbert Anderson, Charles Stuart Everett

Publication number: 20150252122Abstract: A process for making an infusible polyolefin includes the steps of: a) contacting the polyolefin in a sulfonation reactor with a sulfonation mixture comprising sulfur trioxide to produce the infusible polyolefin; b) recovering from the sulfonation reactor a recovery stream having sulfur dioxide; c) oxidizing at least a portion of the recovered sulfur dioxide to produce a recycle stream; and d) combining at least a portion of the recycle stream with the sulfonation mixture of step (a). Another aspect of the invention is for making a carbonized fiber from an infusible polyolefin of the present invention and further includes the step of carbonizing the infusible polyolefin to produce a carbon fiber. Another aspect of the invention is an apparatus for preparing an infusible polyolefin. The apparatus includes a plurality of compartments in fluid communication wherein at least one compartment is adapted for contacting a polyolefin with sulfur trioxide.Type: ApplicationFiled: March 10, 2014Publication date: September 10, 2015Applicant: Eastman Chemical CompanyInventors: Chester Wayne Sink, Ernest Phillip Smith, Robert Thomas Hembre, Jasper Clarkson, Ping Peter Shang

Patent number: 5667575Abstract: Disclosed herein is a method for reducing the color of an emulsion of functionalized polyolefin wax by treating an emulsion with a water soluble oxidizing agent at a temperature above the freezing point and below the boiling point of the emulsion and below the softening point of the wax. Disclosed herein, also, is the essentially colorless emulsion produced according to the disclosed method which is useful as an additive to floor polishes and other coating products.Type: GrantFiled: September 21, 1995Date of Patent: September 16, 1997Assignee: Eastman Chemical CompanyInventors: Paul Andrew Rundquist, Ernest Phillip Smith, Stephen Louis Poteat, Dante Joseph Rutstrom, Richard Kingsley Stuart, Jr.
