The Effect of The Fiber Temperature During Fiber Drawing On The Properties of Primary Coatings

摘要

The high productivity of optical fibers is one of the strong demands in optical fiber manufacturing. One of the solutions to obtain the high productivity is to increase the speed of fiber drawing. However, our previous investigation indicated that the speed of fiber drawing affected mechanical properties of UV curable polyurethane acrylate coatings for optical fiber [1], [2]. The speed of fiber drawing, temperature of fiber glass and coating properties of primary coatings during fiber drawing, and mechanical properties of primary coatings after curing were measured and investigated in this report to design the primary coatings for high speed fiber drawing.
