Patent number: 5614296Abstract: A method of producing self-texturing filaments that exhibit a desirable tendency to coil rather than to bend sharply or zig zag. The method includes directing a quenching fluid at extruded hollow filaments of a liquid polymer predominantly from one side of the hollow filaments to thereby produce hollow filaments with different orientations on each side. Thereafter the temperature of the hollow filaments is raised to a temperature sufficient for the filaments to relax, but less than the temperature at which the filaments would shrink. When the relaxed filaments are cut into staple lengths, they tend to assume a form that provides a favorable degree of mechanical entanglement that is useful in forming resilient solid structures.Type: GrantFiled: September 26, 1995Date of Patent: March 25, 1997Assignee: Wellman, Inc.Inventors: Fred L.
