Abstract: A high population density of closed C shaped cellulose acetate filament can now be reliably produced. The closed C filaments are made from a spinneret having a. substantially D shaped orifice under particular processing conditions depending on the dpf of the filament, the theta angle of the D shaped orifice, and dope temperature. The process can make a high population count of closed C shaped fibers in a. tow band, and article are not provided having the high population density of closed C shaped fibers.

Abstract: 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.

Abstract: 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.

Abstract: A fiber delivery system capable of providing cut fiber segments for use in treating an oil and/or gas well. The fiber delivery system can utilize bales of a continuous filamentary tow that are transported to the well site from a remote manufacturing location. At the well site, a multifilament strand can be pulled off the bale, opened, and cut to provide cut fiber segments. The cut fiber segments can be mixed with other well treatment components to create a well treatment medium that is introduced into the well as part of a drilling, stimulation, or cementing process.
