Method for producing high denier multi-lobal filament of thermotropic liquid crystal polymer and composition thereof |
| abstract |
PROBLEM TO BE SOLVED: To provide a method for producing a high denier multi-lobal filament of a thermotropic liquid crystal polymer as spun and heat-treated. SOLUTION: An extrusion chamber with an extrusion capillary having a multi-lobal cross section for forming a multi-lobal filament is formed by a) heating the thermotropic liquid crystal polymer to a temperature above its melt transition temperature. And c) winding the filament at the appropriate draw-down ratio. The filaments formed are of at least about 50 dpf and have an essentially uniform molecular orientation throughout the cross section. In a final step, the filaments are heat-treated in stages to form filaments that exhibit excellent tensile properties. Both as-spun filaments and heat-treated filaments exhibit significantly better tensile properties comparable to round filaments. The multi-lobal filaments of the present invention exhibit better adhesion than round filaments. |
