  • Self crimpable nylon 66 carpet yarn
    Patent number: 4975325
    Abstract: A melt-spinning process for producing self-crimping, nylon 66 carpet yarn at spinning speeds of, for example 4000 meters per minute is provided. The process utilizes polymer having a relative viscosity (RV) of at least 50 and containing a sufficient amount of a chain branching agent to prevent broken filaments and to provide yarn having good luster.
    Type: Grant
    Filed: June 29, 1988
    Date of Patent: December 4, 1990
    Assignee: Monsanto Company
    Inventors: Stanley E. McKinney, Frank Stutz, Chester C. Wu, Jing-peir Yu
  • Polyamide feed yarn for air-jet texturing
    Patent number: 4816550
    Abstract: Improved feed yarns for air-jet texturing are provided by using high molecular weight polyamide polymer spun through non-round capillaries at high spinning speeds to give filament modification ratios greater than 1.5.
    Type: Grant
    Filed: January 11, 1988
    Date of Patent: March 28, 1989
    Assignee: Monsanto Company
    Inventors: Frank Stutz, Jing-peir Yu, Stanley E. McKinney
  • Process for low-torque textured yarn
    Patent number: 4287713
    Abstract: Spun yarn having torqueless latent crimp is draw-textured, producing a drawn textured yarn which is substantially torque-free.
    Type: Grant
    Filed: July 19, 1979
    Date of Patent: September 8, 1981
    Assignee: Monsanto Company
    Inventors: James E. Bromley, Frank Stutz
  • Deep-dyeing polyester spinning process
    Patent number: 4128989
    Abstract: Polyester yarn is spun at a sufficiently high speed to produce substantial stress-induced crystallinity and low shrinkage. The resulting feed yarn is textured, yielding a textured yarn which dyes considerably deeper than conventional polyester yarns.
