Process For Drawing Acrylic Fibrous Materials To Form A Product Which Particularly Is Suited For Thermal Stabilization And Carbonization
US Patent:
3975482, Aug 17, 1976
Filed:
Jun 10, 1974
Appl. No.:
5/477971
Inventors:
Richard N. Rulison - Medfield MA
Assignee:
Celanese Corporation - New York NY
International Classification:
B29C 2500
B28B 1106
B28B 1106
US Classification:
264131
Abstract:
An improved process for drawing a continuous length of an acrylic multifilament fibrous material is provided. Prior to drawing at an elevated temperature by continuous passage through a suitable drawing zone the surface of the fibrous material is coated with powdered graphite (e. g. colloidal graphite) via contact with a dipersion containing the graphite paticles which serve to improve the drawing properties of the same. The process is suited for the hot drawing of a continuous length of an acrylic multifilament fibrous material (e. g. a substantially untwisted tow) which is intended for subsequent thermal stabilization, and cabonization to form a carbonaceous fibrous material.
