  • A PROCESS FOR PRODUCING POLYMER FIBER AND POLYMER FIBER MADE THEREFROM
    Publication number: 20240117529
    Abstract: The present disclosure relates generally to a process for producing polymer fibers, typically polyacrylonitrile-based fibers, the properties of which are controlled by certain parameters of the process, such as the amount of jet stretch, the amount of wet stretch, and the amount of hot stretch employed. The present disclosure also relates to a process for producing carbon fiber from such polymer fibers.
    Type: Application
    Filed: January 27, 2022
    Publication date: April 11, 2024
    Applicant: Cytec Industries, Inc.
    Inventors: Jeremy Moskowitz, Amy Tucker, Matthew Jackson, Thomas Taylor, Suzanne Crawford, Janos Olah, John Desmond Cook
  • Manufacture of intermediate modulus carbon fiber
    Patent number: 11479881
    Abstract: The present disclosure relates generally to carbon fibers having high tensile strength and modulus of elasticity, as well as a process for the manufacture of such carbon fiber. The process comprises spinning a polymer/solvent solution into a solvent/water bath in the range of 78%-85% solvent, thereby producing a dense fiber structure, and subsequently carbonizing the polymer precursor fiber at a lower than typical carbonization temperature to form carbon fibers.
    Type: Grant
    Filed: February 15, 2016
    Date of Patent: October 25, 2022
    Assignee: Cytec Industries Inc.
    Inventors: John Desmond Cook, Thomas Taylor, Girish Vishnukant Deshpande, Longgui Tang, Barry DeWayne Meece, Suzanne Crawford, Shao C. Chiu, Billy D. Harmon, Alan Thomas
  • CONTROLLING THE DEGREE OF SWELLING OF POLYMER FIBERS DURING COAGULATION
    Publication number: 20210348304
    Abstract: The present disclosure relates to the control of the degree of swelling of polymer fiber, such as polymer fiber used in the manufacturing of composite materials, by control of the pH of the coagulation bath during spinning.
