Publication number: 20210348316Abstract: Fabrics are provided that include mono-component staple fibers, a first group of split staple fibers comprising a first polymeric material, and a second group of split staple fibers comprising a second polymeric material that is different than the first polymeric material. The mono-component staple fibers, the first group of split staple fibers, and the second group of split staple fibers are physically entangled together to define a consolidated nonwoven. The fabrics may be physically entangled by hydroentanglement.Type: ApplicationFiled: July 23, 2021Publication date: November 11, 2021Inventors: Herbert P. Hartgrove, Sayanti Basu, Jerry Snider

Patent number: 9051514Abstract: A liquid crystalline polymer composition that contains a liquid crystalline polymer and an aromatic amide oligomer is provided. The oligomer can serve as a flow aid by altering intermolecular polymer chain interactions, thereby lowering the overall viscosity of the polymer matrix under shear. The oligomer is also not easily volatized or decomposed during compounding, molding, and/or use, which minimizes off-gassing and the formation of blisters that would otherwise impact the final mechanical properties of a part made from the polymer composition. While providing the benefits noted, the aromatic amide oligomer does not generally react with the polymer backbone of the liquid crystalline polymer to any appreciable extent so that the mechanical properties of the polymer are not adversely impacted.Type: GrantFiled: August 27, 2012Date of Patent: June 9, 2015Assignee: Ticona LLCInventors: Kamlesh P. Nair, Joseph J. Grenci, Sayanti Basu, Steven D. Gray

Publication number: 20140076340Abstract: High-throughput production apparatuses, systems, and associated methods may include pneumatic dense phase feeding. For example, a method may involve feeding via pneumatic dense phase feeding a matrix material into a mold cavity to form a desired cross-sectional shape, the matrix material comprising a binder particle and an active particle; heating (e.g., via microwave irradiation) at least a portion of the matrix material so as to bind the matrix material at a plurality of contact points thereby forming a porous mass length; cooling the porous mass length; and cutting the porous mass length radially thereby producing a porous mass. In some instances, the matrix material may include a plurality of active particles, a plurality of binder particles (optionally having a hydrophilic surface modification), and optionally a microwave enhancement additive.Type: ApplicationFiled: November 20, 2013Publication date: March 20, 2014Applicant: Celanese Acetate LLCInventors: Lawton E. Kizer, Raymond M. Robertson, William S. Sanderson, David G. Hunt, Zeming Gou, Christopher D. McGrady, Sayanti Basu, Christian Meermann
