Patent number: 11231408Abstract: Disclosed are fibers which contain identification fibers. The identification fibers can comprise one or more chemical markers, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The disclosure also relates to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and correlating the chemical markers and a taggant chemical marker amounts of at least one of the chemical markers to manufacturer-specific taggants to determine supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer.Type: GrantFiled: November 8, 2017Date of Patent: January 25, 2022Assignee: Eastman Chemical CompanyInventors: Scott Gregory Gaynor, Andrew Ervin McLeod, Michael John Rodig, Jeremy Kenneth Steach, Humberto Collazo, Steven Anthony Wilson, Lydia J.

Publication number: 20200299882Abstract: Nonwoven fabrics and textiles containing cellulose ester fibers particularly cellulose acetate fibers are thermally bonded. An aqueous plasticizing solution is applied to the surface of a nonwoven web and thereafter the web is thermally bonded to create a thermally bonded nonwoven textile. Alternatively, water can be applied to the dry surface of a nonwoven web containing organic plasticizer treated cellulose ester fibers to create the moistened nonwoven web and thereafter thermally bonding the moistened nonwoven web to make a thermally bonded nonwoven textile. The fabrics exhibit an increase in tensile strength and toughness greater than the individual contributions of water and plasticizer alone and greater than the additive contributions of water and plasticizer alone.Type: ApplicationFiled: March 10, 2020Publication date: September 24, 2020Applicant: Eastman Chemical CompanyInventors: Samuel Charles Baer, Jeremy Kenneth Steach

Patent number: 10717029Abstract: Disclosed are fibers comprising identification fibers which can be used for tracking and tracing fibers, yarns, fiber bands, and/or articles comprising the fibers through at least part of the supply chain. Each identification fiber exhibits at least one distinct feature. Each group of distinguishable identification fibers can exhibit a taggant cross-section shape, a taggant cross-section size, or combination of the same taggant cross-section shape and same taggant cross-section size. The distinct features and the number of fibers in each group of distinguishable identification fibers can represent at least one supply chain component of the fibers. The distinct features can be detectable in an article comprising the fibers.Type: GrantFiled: November 28, 2017Date of Patent: July 21, 2020Assignee: Eastman Chemical CompanyInventors: Andrew Ervin McLeod, Scott Gregory Gaynor, Steven Anthony Wilson, Lydia J.

Publication number: 20200071882Abstract: A fiber blend comprising a staple fiber formed from cellulose acetate and a binder fiber. The staple fiber has a crimp frequency of 10 to 30 crimps per inch (CPI), a cut length of 55 mm or less, and a non-round cross-sectional shape. The blend can be made into nonwoven webs for heat-bonding and subsequent use as thermal insulation in, e.g., outerwear, bedding, etc. The cellulose acetate fibers provide superior thermal insulation clo value relative to at equivalent loft.Type: ApplicationFiled: August 14, 2019Publication date: March 5, 2020Applicant: Eastman Chemical CompanyInventors: Loren William Chambers, Charles Stuart Everett, Jeremy Kenneth Steach, Brian Tyndall Edwards
