  • Process for collection of continuous fibers as a uniform batt
    Patent number: 8206640
    Abstract: A process and apparatus for collecting continuous fibers or filaments as a uniform batt comprises a filament emitter in the form of a spinning die, a venturi, a diffuser, and a fiber collection bed. The filaments move downward after being created by the emitter, and exhaust ports create in the diffuser an airflow having a direction against the flow of the filaments so that the filaments are decelerated before contacting the fiber collection bed.

  • Using counter-bore and capillary geometry to control mesophase pitch-based carbon fiber filament micro and macro structure
    Publication number: 20020163107
    Abstract: A spinning die for spinning mesophase pitch into carbon fibers. The die includes a central cavity having a bottom and at least one side wall which intersects the bottom. At least one capillary for forming a fiber is in fluid communication with the cavity, the capillary having a first open end, a second open end, an axis and a diameter (d). A flow disruption shoulder is positioned at the juncture of the bottom of the central cavity and the first open end of the capillary to create turbulence at the capillary entrance.
