  • Technique for forming porous fibers
    Patent number: 11724002
    Abstract: A method for forming a fiber is provided. The method comprises extruding a matrix polymer and a nanoinclusion additive to form a thermoplastic composition in which the nanoinclusion additive is dispersed within a continuous phase of the matrix polymer. The extruded thermoplastic composition is thereafter passed through a spinneret to form a fiber having a porous network containing a plurality of nanopores, wherein the average percent volume occupied by the nanopores within a given unit volume of the fiber is from about 3% to about 15% per cm3.
    Type: Grant
    Filed: January 19, 2018
    Date of Patent: August 15, 2023
    Assignee: Kimberly-Clark Worldwide, Inc.
    Inventors: Ryan J. McEneany, Vasily A. Topolkaraev, Yuewen Xu
  • Porous polyester material
    Patent number: 11154635
    Abstract: A polymeric material that includes a thermoplastic composition containing a continuous phase that includes a polyester and a copolyetherester elastomer is provided. The copolyetherester elastomer is dispersed within the continuous phase in the form of discrete domains. A porous network is defined within the thermoplastic composition that includes a plurality of nanopores.
