Title: Preparation of plastic optical fiber
Inventor: MATSUMIYA NORIBUMI
IPC: G02B6/44
Filed: 1987-01-09
Abstract: PURPOSE:To improve the tensile strength of a high molecular liquid crystal and the whole body of plastic optical fiber by adjusting the feeding speed of the strand of the plastic optical fiber to the speed coinciding the speed of extrusion and coating of the high molecular liquid crystal while it is drawn in the feeding direction of the plastic fiber strand. CONSTITUTION:The feeding speed of the plastic fiber strand is adjusted to coincide to the speed of extrusion and coating of the high molecular liquid crystal while it is drawn in the direction of feeding of the plastic fiber. This condition is necessary for obtaining sufficient tensile strength at the same time when the high molecular liquid crystal is extruded on the plastic fiber strand and coated thereon. The drawing of the high molecular liquid crystal is performed most desirably when a value called by the term of drawing ratio, i.e. (sectional area of the high molecular liquid crystal in the stage of drawing)/(sectional area of the high molecular liquid crystal after coating) is 20-200. Furthermore, since the tensile strength of plastic optical fiber is remarkably improved by this method even if an undrawn plastic fiber strand is used, crystalline material such as copolymer of vinylidene fluoride and tetrafluoroethylene, may be used as the clad material. By this constitution, plastic optical fiber having high tensile strength and heat resistance is obtd.
