  • Patent number: 9695525
    Abstract: The present invention relates to a method for the continuous production of low thermal conductivity endless filament yarns with a compact, homogeneous structural morphology. The presently disclosed methods utilize safe and recyclable ionic liquids (IL) to produce carbon fiber precursors from cellulose. The fibers are produced by the carbonization of cellulose carbon fiber precursors. The precursor fiber filaments have an increased tear resistance with simultaneously sufficient elongation, a round or crenulated cross-section, and homogeneous fiber morphology. The filament yarns exhibit performance characteristics similar to those produced from traditional viscous rayon. The resulting fibers are especially suited for aerospace applications in composite materials used at the limits of high temperatures, for instance in structures found in rocket nozzles or atmospheric reentry heat shields on spacecraft.

  • Patent number: 9433539
    Abstract: A disposable absorbent article has front and back panels, each having an elastic film layer and each having first and second zones. The first zone of each panel is extensible and retractable and the second zone of each panel is non-extensible and non-retractable. Each of the front and back panels has first and second side edges. An absorbent assembly is secured to the front and back panels. The absorbent assembly has a first end secured to the second zone of the front panel and a second end secured to the second zone of the back panel. A pair of seams join the front and back panels together at the first and second side edges to form a disposable absorbent article having a waist opening and a pair of leg openings.
