  • Method of making viscose rayon
    Patent number: 4388260
    Abstract: A crimped, high wet modulus viscose rayon fiber having a multilobular, skin core cross-section wherein the core is surrounded by a discontinuous broken skin that imparts to fabrics an improved cover and hand properties. The fibers are formed from a modifier-free viscose. The elimination of the modifier reduces manufacturing costs and eliminates an environmental pollution problem created in the discharge of spinning baths containing modifiers.
    Type: Grant
    Filed: January 8, 1981
    Date of Patent: June 14, 1983
    Assignee: Avtex Fibers Inc.

  • Viscose rayon and method of making same
    Patent number: 4242405
    Abstract: High wet modulus viscose rayon fiber having a skin core structure and having a multi-lobular cross-section that imparts to fabrics an improved cover and hand properties similar to those of cotton. The fibers are formed from a modifier-free viscose. The elimination of the modifier reduces manufacturing costs and eliminates an environmental pollution problem created in the discharge of spinning baths containing modifiers.

  • Crimped, high-strength rayon yarn and method for its preparation
    Patent number: 4121012
    Abstract: A crimped, high-strength regenerated cellulose yarn of filaments having a broken skin-core cross-sectional structure of which the skin comprises at least about 20 up to about 40% of the cross-sectional area, the peripheral skin surface is substantially smooth and the core section is "blown-out;" and a method of preparing the yarn from a specified viscose and spinning bath wherein the formed yarn is highly stretched and then crimped in the relaxed state in a plasticizing medium.
