  • Process for polyester fine hollow filaments
    Patent number: 5585182
    Abstract: A post-coalescence melt-spinning process for preparing fine undrawn hollow polyester filaments having excellent mechanical quality and uniformity at high speeds (2-5 km/min) involving selection of polymer viscosity and spinning conditions, whereby the void content of the resulting new undrawn filaments is essentially maintained or increased on cold-drawing or hot-drawing with or without post heat treatment, and the new fine hollow polyester filaments obtained thereby.
    Type: Grant
    Filed: March 1, 1995
    Date of Patent: December 17, 1996
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Arun P. Aneja, David G. Bennie, Robert J. Collins, Hans Rudolf E. Frankfort, Stephen B. Johnson, Benjamin H. Knox, Elmer E. Most, Jr.

  • Process for increasing void volume of hollow filaments
    Patent number: 4444710
    Abstract: A process for increasing the percent void of hollow filaments by contacting the filaments with water at a temperature of at least about 92.degree. C. for at least about 3 seconds. It is necessary that the treatment be carried out while the filaments are in an amorphous condition. Preferred filaments are polyesters.

  • Splittable hollow polyester filament
    Patent number: 4407889
    Abstract: Hollow filaments having longitudinal grooves and ridges that are readily split along the grooves and are especially adapted for use in a flocking process to form flocked products with a surface similar to suede. The hollow filaments have a denier of about 0.8 to about 3.35 and have a void area of 15 to 30% of the total area of the cross section of the fiber.
